Texto completoToxoplasmosis, caused by Toxoplasma gondii and highly prevalent protozoan disease in Brazil, is mainly transmitted by ingestion of contaminated food and water, both by oocysts, excreted in cat feces, or cysts from undercooked meat from warm-blooded animals. Usually asymptomatic, it is extremely severe in the fetus or immunosuppressed patients. In this work, we studied the serological prevalence of toxoplasmosis in animals from several regions of the São Paulo State, both free living, as dogs (ABC) as environmental contamination index, and cats (São Paulo, as definitive hosts, or livestock as cattle (Taquarituba), swine (Osasco), goats (Botucatu), sheep (São Manuel) and fowls (São Paulo), with parasitological studies in cats and suspicious drinking water. We standardized ELISA for each species, using reproducible and adequate indexes, with Western blot confirmation and avidity assays in positive samples. Toxoplasmosis prevalence was increasing in swine (8.5%), cattle (11%), goats (17%), sheep (31%), cats (40%) and dogs (50.5%), without positive sample in fowls. Goats, pigs, dogs and cats presented 5-20% low avidity antibody samples, suggesting sustained transmission during animal life, but cattle and sheep presented only high avidity samples, suggesting an seasonal or early in life infection. Due to the high recent infection rate in cats, it is possible to preview a significant oocyst excreting cat frequency, despite parasitological evidence. Antibody determination must be carefully evaluated, as human hemagglutination reagents give erratic information. Oocyst detection in drinking water presented very low sensitivity and must be performed only in water collected at the period of the infection. In São Paulo, almost all of tested sources are able of toxoplasmosis transmission, reinforcing the need of better management of livestock, adequate water treatment and elimination of free living cats.

Texto completoRecombinant proteins from Toxoplasma gondii have been used in several experimental models, as well as for serodiagnosis of human toxoplasmosis, particularly to differentiate acute from chronic phases of the infection. In the present study, we evaluated the kinetics of IgM, IgA, and IgG isotypes, in addition to IgG1 and IgG3 subclasses, by testing sequential serum samples from patients with acute toxoplasmosis. It was carried out immunoassays by using SAG2A recombinant antigen and soluble antigen of Toxoplasma (STAg). The avidity of IgG1 antibody was assessed using slot blot assay. Additionally, a ratio between IgG1 and IgG3 subclasses (IgG3:IgG1) was determined and evaluated its degree of association with levels of IgM and IgA specific for STAg and the avidity index of IgG1 specific for SAG2A. The results showed a decreasing kinetic profile for SAG2A and STAg for IgM and IgA. The kinetic profile for the IgG antibody was increasing for both antigens. Compared to the avidity for IgG1, it was observed that sera from an early stage showed a low average avidity of IgG1 for SAG2A while the same samples showed intermediate mean avidity of IgG1 when STAg was used as antigen. In a later phase, the average avidity observed was high for STAg and intermediate for SAG2A in the same tested sera suggesting that SAG2A may be a promising tool for the detection of avidity. Associations between IgG3/IgG1 and specific IgM and IgA levels for STAg and the avidity index of specific IgG1 for SAG2A were found, and together these parameters could be used as valuable tools in the diagnosis of human toxoplasmosis, especially in situations when the determination of different phases is critical.
Proteínas recombinantes de Toxoplasma gondii têm sido utilizadas em diversos modelos experimentais, assim como para o diagnóstico sorológico da infecção humana por este parasito, principalmente com o intuito de diferenciar as fases aguda e crônica da toxoplasmose. Neste estudo, foi avaliada a cinética dos anticorpos IgM, IgA ,IgG e subclasses (IgG1 e IgG3) através de imunoensaios realizados em amostras seqüenciais de soros humanos, provenientes de pacientes com toxoplasmose aguda. Estas amostras foram testadas frennte ao antígeno recombinante SAG2A, utilizando-se como paradigma de comparação o antígeno solúvel total de Toxoplasma (STAg). A avidez do anticorpo IgG1 foi avaliada utilizando a metodologia slot-blot. Adicionalmente, a razão entre as subclasses IgG3 e IgG1 (IgG3:IgG1) foi determinada e avaliada quanto ao grau de associação com os níveis de IgM e IgA específicos para STAg e aos índices avidez de IgG1 específicos para SAG2A. Os resultados demonstraram a presença de níveis decrescentes de IgM e IgA para ambos os antígenos utilizados, enquanto que para o isotipo IgG o perfil cinético demonstrou níveis crescentes para ambas preparações antígênicas. Em relação aos índices de avidez para IgG1, foi observado que amostras de soros de uma fase inicial apresentaram baixa avidez média de anticorpos IgG1 dirigidos para SAG2A, enquanto que as mesmas amostras demonstraram avidez média intermediária de IgG1 quando STAg foi utilizado como antígeno. Já em uma fase mais tardia, a avidez média observada foi alta para STAg e intermediária com SAG2A. A razão entre IgG3:IgG1 obtida no primeiro bimestre foi significantemente maior para SAG2A em comparação com STAg. Tomados em conjunto, os resultados obtidos no presente estudo indicam que a proteína recombinantes SAG2A pode se constituir em uma ferramenta efetiva na diferenciação das fases da infecção humana por T. gondii.

Unfortunately, these tests gave no information about the Xga protein because the position of the Xga band was masked by the antibody light chain which became labelled. However, a 32 kD band was seen in the Xga-immunoprecipitate from Xg(a+) but not from Xg(a-) cells [50]. It has not yet been proved that this is the CD99 protein because this band was not stained by immunoblotting Xga-immunoprecipitates with 12E7. The luciferin-enhanced luminescent proceedure to detect the avidin-biotin label is very much more sensitive than immunoblotting. Our results support the theory that Xga and CD99 may be associated in the membrane. Cloning of the XG gene will increase our understanding of this relationship. The important blood group genes have been cloned but two big problems remain, regulation on antigen expression and the function of blood group polymorphisms. Rare phenotypes should still be studied because they will contribute to unravelling the mechanisms responsible for the polymorphisms. The wealth of serological information which continues to increase includes many examples of variable expression of red cell antigens. Some antigens do not show the same variation on other cells suggesting that some modes of regulation may be limited to red cells. Association of blood group antigens with proteins of known function and identification of red cell antigens on cells other than red cells will contibute to understanding the functions of the blood group polymorphisms.

CD99 was first detected by 12E7, a monoclonal antibody made in response to a T-cell line, and was initially thought to be a ‘thymus-leukaemia’ marker antigen [41]. Many similar antibodies were made which reacted with different epitopes of the same molecule [see 42]. Independently, CD99 was identified as E2, a T-cell adhesion molecule, and as a marker antigen for Ewing’s tumours [see 40]. CD99 is expressed on many tissues including red cells. By somatic cell hybridization and biochemical studies, Goodfellow and his colleagues have shown that MIC2, the structural locus encoding the 12E7 antigen, is located on the short arm of the X chromosome and on the short arm of the Y chromosome within the pairing regions [43]. MIC2 has been cloned [44]. XG is X-borne. On red cells, CD99 expression is a quantitative polymorphism [45]. Family studies proved that this polymorphism is also caused by regulator genes on X and Y chromosomes. XG appears to be the regulator on the X [46]. There is variation in CD99 expression on cells other than red cells. In a recent publication, CD99 was found on all haemopoeitic cells but was variably expressed during leucocyte differentiation [40]. Use of different monoclonal antibodies and variability of expression during maturation offered an explanation for the previous apparently contradictory findings by different laboratories. Both Xga and CD99 are sialoglycoproteins [47,48,49]. These glycoproteins differ in Mr and in their sialic acid content [49]. Immunostaining of separated membrane components with 12E7 and similar antibodies had demonstated that the MIC2 gene product was a 30-32 kD protein. 12E7 also bound to an intracellular band of 28 kD which was found in mouse cell lines in addition to human cell lines, platelets, lymphocytes and red cells but it was not encoded by the MIC2 gene [47]. Immunoblotting assays have shown that Xga was associated with two diffuse bands of 22-25 kD and 26.5-29 kD [49]. These findings supported the evidence that Xga and CD99 were products of different structural loci. However, XG appears to regulate CD99 expression on red cells and Latron and colleagues found that purified CD99 protein inhibited binding of 12E7 and of anti-Xga to red cells [48]. We have studied the immunochemical relationship of Xga and CD99 [50]. One approach was immunoprecipitation of membrane components from biotin labelled cells. Bands are detected by chemiluminescence via peroxidase-conjugated avidin. The 32 kD protein of CD99 was visualised by this technique and the quantitative polymorphism was also demonstrated since the 32 kD band is seen on X-ray film after 2 minutes in membranes".
