Abstract:
The severity of a transfusion reaction depends on alloantibody titres within the recipients' blood. Determination of an agglutination titre of naturally occurring alloantibody may help to assess the risk of transfusion reactions following an unmatched transfusion in a cat population. In this group of 312 cats 227 had blood type A, 78 had blood type B, and seven had type AB blood. All type B cats tested showed gross evidence of agglutinating anti-A antibody with plasma titres ranging from 2 to 256. Among the 227 type A domestic cats tested for plasma anti-B alloantibody titres, 70% had gross agglutination with titres ranging from 2 to 16, while 17.6% had microscopic agglutination. The remaining 12.4% of the type A cats were negative for both gross and microscopic agglutination. Based on agglutinating titres, the relative risk of a transfusion reaction when type A or AB blood was given to a type B cat was 6.4% with acute severe reaction, acute mild reactions in 85.9% and premature red cell destruction in 7.7%. On the other hand, transfusion of type AB blood or type B blood to type A cats carries a potential risk of acute mild transfusion reaction in 4.4% and premature red cell destruction in 83.3%. Transfusion of type A or B blood to type AB cats results in no apparent clinical transfusion reactions.

Abstract:
B3 is the most common subtype of blood group B in the Taiwanese population, and most of the B3 individuals in the Taiwanese population have the IVS3 + 5 G > A (rs55852701) gene variation. Additionally, a typical mixed field agglutination is observed when the B3 subtype is tested with anti-B antibody or anti-AB antibody. The molecular biology of the gene variation in the B3 subtype has been identified, however, the mechanism of the mixed field agglutination caused by the type B3 blood samples is still unclear. Therefore, the purpose of this study was to understand the reason for the mixed field agglutination caused by B3. A micro-droplet platform was used to observe the agglutination of type B and type B3 blood samples in different blood sample concentrations, antibody concentrations, and at reaction times. We found that the agglutination reaction in every droplet slowed down with an increase in the dilution ratio of blood sample and antibody, whether type B blood or type B3 blood was used. However, as the reaction time increased, the complete agglutination in the droplet was seen in type B blood, while the mixed field agglutination still occurred in B3 within 1 min. In addition, the degree of agglutination was similar in each droplet, which showed high reproducibility. As a result, we inferred that there are two types of cells in the B3 subtype that simultaneously create a mixed field agglutination, rather than each red blood cell carrying a small amount of antigen, resulting in less agglutination.

Abstract:
Background: Widal tube agglutination test is a widely used laboratory test for diagnosis of enteric fever especially in resource limited countries where blood culture are not routinely available. We studied the titres from different groups including febrile and healthy populations in order to identify the significant agglutination titre. Materials and Methods: This was a hospital based cross-sectional study. Subjects were divided into three groups: 1) 60 healthy blood samples from volunteer students, 2) 60 febrile non-typhoidal cases and 3) 58 culture positive patient for enteric fever. Results: Among 60 apparently healthy volunteers, agglutination of ≥ 1:20 for anti O and anti-H titres against serotype Typhi were seen in 40 and 46 samples respectively. A significant proportion of sample had a titre of ≥1:80 (n=19) and 1:160 (n=14) for anti O and anti-H titres against serotype Typhi respectively among healthy individuals. Similar observations were seen in febrile non typhoidal cases except for one which had a titre of ≥1:320 for anti O and anti-H titres against serotype Typhi. In blood culture positive typhoid cases, 56 samples showed agglutinations of ≥1:80 for both anti O and anti-H titres against serotype Typhi. However two of the total sample tested showed no agglutinations. In all cases from three groups, anti-H titre for S. enterica serotype Paratyphi A and B were below 1:80. Conclusions: Widal test can be used as presumptive diagnostic tool in all the suspected cases of enteric fever if the titres are specifically raised.Keywords: enteric fever; titre; widal aggultination test.

Abstract:
Abstract Background: Despite transfusion of Rh matched red cells for patients with sickle cell disease, Rh alloimmunization remains a persistent challenge. Rh specificities can be complex, resulting from RH genetic diversity found in patients and donors. Antibody identification is hampered by the lack of appropriate reagent red cells, especially those that can identify antibodies against high prevalence or low prevalence Rh antigens. We used human induced pluripotent stem cells (iPSCs) with the goal of producing renewable red cell reagents to both screen for Rh alloimmunization and to aid complex antibody identification. Methods: We generated a panel of iPSCs that include Rh null, D--, lack the high prevalence antigens hr S or hr B, or express uncommon Rh antigens such as V, VS, Go a, or DAK. For the Rh null line, we used CRISPR/Cas9 genetic engineering to disrupt RHCE via a large deletion in a D- iPSC. For D--, RHD was inserted into the AAVS1 safe harbor locus of an Rh null iPSC line using zinc finger nucleases resulting in a line that constitutively expresses RhD but no RhCE. iPSCs with uncommon variants were reprogrammed from RH genotyped donors or engineered similar to the generation of the D-- line. Hematopoietic differentiation by embryoid body formation was used to generate hematopoietic progenitors that were subsequently cultured towards the erythroid lineage. Mature iRBCs were ficin treated and tested with patient plasma with previously identified Rh antibodies using gel agglutination assays. Results: Rh null iPSC-derived RBCs (iRBCs) showed complete absence of cell surface Rh protein by flow cytometry, while D-- iRBCs showed Rh protein expression levels comparable to D-ce+ iRBCs using an anti-D/CE antibody. We assessed RBC agglutination of Rh null, D--, hr S-, hr B-, VVS+, Go a+, and DAK+ iRBCs using standard Rh typing reagents (Ortho). The reprogrammed uncommon donor iRBCs agglutinated with monoclonal anti-Rh antibodies as predicted by RH genotype, while the Rh null iRBCs showed no agglutination with all 5 common Rh antibodies and D-- iRBCs showed agglutination with anti-D reagents only. Rh null iRBCs showed no agglutination against patient plasma containing anti-D, while D-- iRBCs agglutinated. While D- RHCE*ce homozygous iRBCs showed strong agglutination against patient plasma containing anti-hr S, Rh null, D--, and hr S- iRBCs did not agglutinate. No iRBCs showed agglutination by plasma containing anti-V/VS while VVS+ iRBCs showed strong agglutination. Similarly, no iRBCs showed agglutination by plasma containing anti-Go a while Go a+ iRBCs showed strong agglutination. Detection of most antibodies against Rhce on iRBCs was enhanced by ficin treatment whereas antibodies with D specificity did not require ficin treated cells for detection. Conclusion: We suggest that genetically engineered iPSCs expressing uncommon Rh antigen phenotypes that are difficult or impossible to obtain from red cell donors can expedite antibody identification. Rh null and D-- iRBCs could be useful to discriminate antibodies against RhD versus RhCE. Customized iPSCs that lack high prevalence or express low prevalence Rh antigens could potentially standardize antibody evaluation in patients with complex Rh specificities.

Abstract:
AbstractBinding of von Willebrand factor (VWF) to the platelet membrane glycoprotein (GP) Ib-IX-V complex initiates a signaling cascade that causes αIIbβ3 activation and platelet aggregation. Previous work demonstrated that botrocetin (bt)/VWF–mediated agglutination activates αIIbβ3 and elicits adenosine triphosphate (ATP) secretion in a thromboxane A2 (TxA2)– and Ca2+-dependent manner. This agglutination-elicited TxA2 production occurs in the absence of ATP secretion. However, the signaling components and signaling network or pathway activated by GPIb-mediated agglutination to cause TxA2 production have not been identified. Therefore, the focus of this study was to elucidate at least part of the signal transduction network or pathway activated by GPIb-mediated agglutination to cause TxA2 production. The phosphatidylinositol 3-kinase (PI3K) selective inhibitor wortmannin, and mouse platelets deficient in Lyn, Src, Syk, Src homology 2 (SH2) domain–containing leukocyte protein 76 (SLP-76), phospholipase Cγ2 (PLCγ2), linker for activation of T cells (LAT), or Fc receptor γ-chain (FcRγ-chain) were used for these studies. LAT and FcRγ-chain were found not to be required for agglutination-driven TxA2 production or activation of αIIbβ3, but were required for granule secretion and aggregation. The results also clearly demonstrate that bt/VWF-mediated agglutination-induced TxA2 production is dependent on signaling apparently initiated by Lyn, enhanced by Src, and propagated through Syk, SLP-76, PI3K, PLCγ2, and protein kinase C (PKC).

Abstract:
An investigation into the genetic differences in the humoral immune response of swine following vaccination with a sheep red blood cell solution (SRBC) and a commercially prepared Pasteurella multocida (serotype A) bacterin (PmA) was conducted on a total of 268 pigs from two individual trials. This study was also conducted to evaluate the humoral immune response of pigs to a non-pathogen (SPEC) and a known pathogen to swine (PmA). The pigs used in the first trial were from 22 litters born between January 1991 and July 1991. The pigs consisted of Hampshire x Yorkshire (n=114), purebred Yorkshire (n=70) and Hampshire (n=17). Individual pigs were vaccinated at five and eight weeks of age with 2 ml of a 5% SRBC solution and 1 ml of a killed PmA bacterin. AL 11 weeks of age 8 uE of blood was collected frun each animal and serum prepared to determine antibody titer levels against the two antigens by agglutination methods. Pigs utilized in the second study consisted of purebred Duroc (n=11), Haupshire (n= 10), Landrace (n=12) and Yorkshire (n=11) and crossbred Hampshire X Durcc (n= 12) and Yorkshire X Landxace (n=12). Results of trial 1 indicate that breed of pig affected the immune response against both PmA (P<.01) and SRBC (P<.01), with the Hampshire x Yorkshire crossbred pigs having higher titer levels against the PmA than either Hampshire or Yorkshire purebred pigs. The purebred Hampshire were not statistically different from either the purebred Yorkshire or the Hampshire x Yorkshire crossbred pigs in their antibody response to SRBC; however, the Hampshire x Yorkshire crossbred pigs were statistically higher than the Yorkshire pigs. Results from trial 2 indicate highly significant (P<.01) breed differences in the humoral immune response to PmA. Purebred Landrace pigs were superior to both Duroc and Hampshire purebred pigs in their immune response to PmA. Purebred Yorkshire and crossbred Yorkshire X Landrace pigs were superior to purebred Durtcs in their immune response to PmA. NO other significant differences among breeds of pigs occurred in trial 2. A low positive correlation of .22 was found between the pigs' antibody responses to PmA and SRBC in trial 1. Correlation differences among breeds were found between average daily gain while an test and the humoral immune response to both PmA and SRBC. Results suggest that further studies into breed differences of the immune response in swine are warranted. Results also suggest that further studies are needed to evaluate sheep /Ed blood cells as a suitable antigen When conducting research to analyze the humoral immune response in swine.

Abstract:
La détection ou la quantification dans le sang de biomarqueurs peut apporter une précieuse information sur la santé humaine. Cette analyse peut être réalisée directement auprès du patient, on parle alors de POC (point-of-care). L’agglutination de globules rouges par un réactif bispécifique, ciblant d’une part un globule rouge et d’autre part le biomarqueur à doser ou détecter, est proposée comme principe de base d’un test POC autonome et quantitatif. L’automatisation du protocole d’agglutination en microfluidique, ainsi que la mesure optique de la cinétique de l’agglutination sont explorées selon trois questions. La première concerne la possibilité de produire de manière autonome et reproductible l’agglutination en microfluidique passive, c’est-à-dire sans apport d’énergie ni de matière autre que l’échantillon. Les deuxième et troisième questions concernent la mesure de la cinétique d’agglutination et l’existence d’un lien entre cette mesure et la concentration du biomarqueur. La formulation et l’embarquement du réactif se sont révélés indispensables pour effectuer une réaction d’agglutination de manière reproductible en microfluidique passive et répondre à la première question. Trois stratégies de mesure de l’agglutination basées sur les propriétés optiques des globules rouges ont été proposées. Deux d’entre elles ont pu être implémentées avec succès. La mesure cinétique de l’agglutination a été mise en place pour un modèle de typage sanguin et a permis la discrimination entre positif et négatif dans 100 % des cas d’agglutinations testés. L’effet de la concentration du biomarqueur sur la mesure de l’agglutination avec un réactif bispécifique a été démontré avec le modèle du biomarqueur D-dimère, répondant à la dernière question posée en début de thèse
The detection or quantification of biomarkers in the blood can provide valuable information on human health. An analysis directly performed at the patient bedside is called a Point-of-care test (POC). The agglutination of red blood cells by a bispecific reagent combining a biomarker binding part and an erythrocyte binding part is proposed as a basis for an autonomous and quantitative POC test. The integration and automation of the protocol in a microfluidic chip and the optical measurement of the kinetics of agglutination are investigated. The first question concerns the possibility of producing agglutination in passive microfluidic device that is to say without any energy nor any material supply other than the sample. The second and third questions respectively relate to the measurement of the kinetics of aggregation and the existence of a link between this measure and the concentration of the biomarker. The formulation and embedding of the reagents has proved essential to perform a reproducible agglutination reaction in passive microfluidics and thus answer the first question. Three measurement strategies based on the optical properties of the red blood cells have been proposed. Two of them have been successfully implemented. The kinetic measurement of agglutination has been performed for a blood typing model and allowed the discrimination between positive and negative agglutination reaction in 100 % of the experiments. The effect of biomarker concentration on the agglutination measurement has been demonstrated with the model of the biomarker D-dimer, answering the last question

Abstract:
För att undvika komplikationer vid blodtransfusioner fenotypas blodgivarens blod med avseende på kliniskt relevanta blodgruppsantigen. Fenotypning innebär att erytrocytantigen påvisas, vilket kan utföras med bland annat rör- eller gelkortsteknik. Dessa tekniker bygger på antigen-antikroppsreaktioner, agglutination. Agglutinat kan uppstå direkt när antikroppar binder samman erytrocyter eller uppstå sekundärt när antihumanglobulin reagerar med antikroppar bundna till erytrocyter. Syftet med studien var att jämföra rörteknik och gelkortsteknik för fenotypning avantigenerna RhC, -c, -E, -e inom Rh-systemet samt antigenerna inom Kell- (K), Duffy-(Fya)och Kidd-systemen (Jka). Detta med avseende på säkerhet, tid, ekonomi samt att utföra en validering av fenotypning med gelkortsteknik. Blod från 80 blodgivare fenotypades manuellt (direkt agglutination och indirekt antihumanglobulinteknik) med rör- och gelkortsteknik.Resultaten visade ingen skillnad mellan rör- och gelkortsteknik avseende de i studien fenotypade erytrocytantigen. Resultaten visade att rörtekniken är ett kostnadseffektivt verktyg för fenotypning. Totalkostnaden för fenotypning av 20 blodprover var 1157,06 SEK med rörteknik respektive 1337,11 SEK med gelkortsteknik. Men tack vare högre säkerhet, ökad effektivitet och bättre prestanda är gelkortsteknik att föredra även om den medför endast en ringa merkostnad. Gelkortstekniken ger en ökad säkerhet för både den som utför analysen genom minskad smittrisk samt för patienten eftersom tolkningsosäkerheten och tolkningsdifferensen minskar. Ett byte från rörteknik till gelkortsteknik är därför att rekommendera för blodcentralen vid länssjukhuset i Kalmar.

Blood typing assay is a critical test to ensure the serological compatibility of a donor and an intended recipient prior to a blood transfusion. Mistyping of blood group in transfusion might result in intravascular hemolysis, renal failure and shock. This thesis presents a microfluidic blood typing system using a small quantity of blood sample to determine the degree of RBC agglutination. This microfludic blood typing chip comprises five injection inlets and a detection chamber. An interdigitated electrode (IDE) array, acting as a sensor for the measurement of blood agglutination, exists inside the detection chamber. Moreover, two measuring methods were proposed: impedimetric measurement and electroanalytical measurement. The charge transfer resistance in the impedimetric measurement and the power parameter in the electroanalytical measurement were used for the analysis of agglutination level. From the experimental results, both measuring methods provide quantitative results and the parameters are linearly and monotonically related with the degree of RBC agglutination. However, the electroanalytical measurement is more reliable than the impedimetric technique because the impedimetric measurement may suffer from many influence factors, such as chip conditions. Five levels from non-agglutination (level 0) to strong agglutination (level 4+) can be discriminated, conforming to the clinical requirement to prevent any risks in transfusion. This proposed approach provides unambiguous quantitative identification of agglutination level for blood typing.

Abstract:
Leptospirosis is a zoonosis caused by spirochetes of the genus Leptospira. It has a worldwide distribution with greater occurrence in tropical and subtropical countries. It is endemic in Brazil. It affects domestic, wild and production animals. The goal of this study was to assess dairy herd productive and reproductive indexes on a monthly basis by serologically monitoring the infection dynamics on two experimental groups: one with animals with negative results at study onset (G-1) and another with animals tested positive for at least one leptospira serovar (G-2). The serum microscopic agglutination test (MAT) was employed. Animals with titer equal to or greater than 100 IU were considered reactive. Animals were evaluated for productive and reproductive indexes based on data provided by the dairy’s IT system. Blood was collected from all animals in both groups once a month for nine months. Analysis showed interference between animals seroreactive to leptospirosis and both milk production and number of pregnancies for G-2 at collection moments 3, 4, 5, 6, 7 and 9 whereas for G-1 the same indexes showed decrease only in the 5th and 9th study months. The most prevalent serovars were Hardjoprajitino 59.5%, Pyrogenes 21.04%, Pomona 11.07%, Wollfi 11.07%, Hardjo 8.78%, Guaricura 6.55%, Copenhageni 5.09%, Icterohaemorrhagiae 1.11%, and Ctg 0.83%. Serovar Hardjoprajitino showed a relationship with herd milk production decrease.

Abstract:
Many bacterial infections can cause multisystem or metastatic infection, commonly through haematogenous spread, with preferred sites or tropism depending upon specific organism. For example, Staphylococcus aureus is a well-recognized cause of infective endocarditis, joint infection, and vertebral osteomyelitis. Klebsiella pneumoniae can cause endogenous endophthalmitis in association with a pyogenic liver abscess, a syndrome well described in East Asia. Streptococcus pneumoniae typically causes lower respiratory tract infections or bacterial meningitis. The combination of meningitis, pneumonia, and endocarditis is called ‘Austrian syndrome’ and is strongly associated with hyposplenism or alcohol abuse. Other examples of bacteria that disseminate and cause multisystem infection are covered elsewhere. C. albicans or non-albicans species in the blood can metastasize to the eye (causing chorioretinitis or endophthalmitis) or to the heart (causing infective endocarditis). The primary sites of infection are commonly the GI tract or intravascular catheters, and high-risk groups include patients who have recently undergone abdominal surgery, received multiple courses of intravenous antibiotics, and are receiving total parenteral nutrition. Empirical treatment is with either IV liposomal amphotericin or an echinocandin before stepping down to an oral azole, commonly fluconazole at a dose of 400mg od. Because of the risk of metastatic spread, minimum duration is normally two weeks after the first negative blood culture. Cryptococcosis is caused by one of two species: Cryptococcus neoformans or Cryptococcus gattii. Unlike C. neoformans, C. gattii can cause infection in immunocompetent people. The clinical syndrome, Cryptococcosis, is an opportunistic infection for AIDS, but other conditions that predispose to infection are lymphoma, sarcoidosis, liver cirrhosis, and corticosteroids. Following inhalation, cryptococci can disseminate to the cerebrospinal fluid (CSF) and cause meningitis. Occasionally, Cryptococcoma—umbilicated papules on the skin— can occur. Symptoms are often subacute and include fever and dry cough. Following dissemination to the CSF, headache and confusion can occur. Diagnosis is based upon detection of capsular antigen by latex particle agglutination or culture, typically from blood or CSF. For meningitis, treatment consists of three phases. The induction phase is two weeks of IV liposomal amphotericin and flucytosine, followed by consolidation with eight weeks of oral fluconazole 800mg once daily, then finally secondary prophylaxis, 200mg orally once daily.

Abstract:
An original observation of platelet agglutination was found in a 63 y.o. man during 5 years following, without spontaneous bleeding. Low platelet counts (10 × 109/liter) and large agglutinates were observed on blood specimens collected into EDTA (1 to 15 mg/ml whole blood WB), citrate (1/10 volume citrate 0.11 M), sodium heparin (100 units/ml WB), citrate plus acetyl salicylic acid (5 to 100 mg/ml WB), citrate plus prostacyclin (Upjohn 10−5 to 10−6 M)? and buffering anticoagulant (0.8 M citrate, pH 4.65). Low platelet count and large agglutinates were also observed in capillary blood obtained by finger puncture kept at 22° or 37°C. All techniques revealed significant clumping making assessment of overall platelet number impossible. Bleeding time Ivy horizontal incision is longer than 20 minutes.Patient's serum induced normal platelets agglutination up to a 1/512 dilution at 22°and 37°C temperature. Lack of agglutination after treatment of the serum by IgM and indirect immunofluorescence tests identified the IgM nature of the agglutinating factor. This antibody reacted with Glanzmann thrombasthenia platelets ruling out the IIb/IIIa complex as the target of this agglutinin.There was no evidence of platelet activation following agglutination of autologous or alldgenic platelets : electronic microscopy of native blood platelets clumps did not show any sign of activation, and plasma level of B-thromboglobulin was normal in this patient. Normal platelets agglutination by patient's serum was not accompanied with ATP secretion (luciferin-luciferase).This IgM agglutinin was associated with elevation of IgM (700 mg/dl) without clinical or biological signs of auto-immune disease.No similar case with irreversible platelet agglutination in both capillary or venous blood has been reported before. The significance of the observation remains obscure.

Abstract:
Effects on filamentous proteins appear to be a central phenomenon in the neuronal toxic effects of organic solvents. We have therefore compared the effects of some organic solvents (particularly isopropylalcohol, IPA) to the previously observed effects of dibucaine (DBC) on platelet cytoskeletal proteins. Incubation of platelets with 6% IPA at 37° C, like DBC, initiates a degradation of actin-binding protein (ABP) as substrate for a calcium activated protease (CAP), shown by SDS-PAGE. IPA leads to an increase followed by a decrease in bovine von Willebrand factor-induced agglutination. The decrease is accompanied by a release of glycocali-cin from the GP lb α-chain. The process was also studied using CIE of Triton X-100 extracts of platelets against antiserum to glycocalicin. Incubation of platelets with IPA before extraction in the presence of 4.2 mM leupeptin leads to a time-dependent transformation of GP Ib-related immunoprecipitates from that of the slow-migrating peak III complex (probably between ABP and GP lb) to the faster migrating GP Ib-precipitate. Our working hypothesis is that IPA induces an activation of the CAP by mobilizing calcium. This leads to degradation of ABP and liberation of GP lb from the cytoskeleton accompanied by an increased tendency for agglutination. The following decrease is explained by degradation of the glycocalicin part of the GP lb enchain which contains the binding-site for von Willebrand factor. We conclude that IPA has a similar effect on GP lb and ABP as DBC. Preliminary studies with 1% DMSO and 0,005% toluene at 37° C revealed that these organic solvents have some similar effects on platelets as described for IPA. Possibly the described effects are characteristic of certain cells at an early stage in a process ultimately leading to cell lysis.
