"Parasitoses intestinales en Guinée : Epidemilologie moléculaire des Protozoaires Blastocystis et Cryptosporidium et Implication de ces microorganismes dans les modifications du microbiote intestinal."

Повний текст джерелаIntestinal parasitic infections have a major impact on public health, particularly in developing countries where these infections are endemic and remain one of the primary causes of morbidity and mortality in the population. Sub-Saharan African countries are the most affected, due to poor sanitation conditions and inadequate drinking water sanitation systems, combined with poverty and crowded living conditions that facilitate the transmission and spread of these parasitic infections. Yet, these infections remain largely underestimated in many African countries, such as Guinea. An initial review helped assess the situation regarding neglected tropical diseases, which are a priority for the Guinean Ministry of Health. However, this overview did not include intestinal parasitic infections, focusing instead on helminthiases. Therefore, a systematic review and meta-analysis were conducted to evaluate the prevalence of these infections in Guinea. However, data on the potential impact of intestinal protozoa like Blastocystis sp. and Cryptosporidium spp. were almost non-existent. Consequently, large-scale field epidemiological surveys were conducted in the Conakry region to obtain, using molecular methods, the first prevalence rates and subtyping data for these two protozoa. A very high prevalence (78%) of Blastocystis sp. was observed in a cohort of 500 individuals, highlighting an active circulation of this parasite within the Guinean population. Additionally, subtyping of the isolates revealed a marked predominance of anthroponotic subtypes (ST1-ST4) of Blastocystis sp., indicative of extensive human-to-human transmission. In parallel, the identification of a significant number of ST14 isolates, which are adapted to cattle, suggested notable zoonotic transmission. Concerning Cryptosporidium spp., its prevalence in a group of over 800 participants was only 0.12%, with a single C. hominis isolate identified. However, this frequency aligns with those reported in other African countries when examining general populations rather than young children, who are more susceptible to this infection. In relation to the high prevalence of Blastocystis sp., the first study in Guinea was conducted on the impact of colonization by this protozoan on the intestinal microbiota. This colonization significantly impacts the bacterial gut microbiota, with a much less pronounced effect on the eukaryotic microbiota. This study thus provided new evidence of the beneficial impact of anthroponotic STs of Blastocystis sp. on the gut microbiota, as colonization by the protozoan was associated with positive effects on the diversity and bacterial composition of this ecosystem. All these epidemiological data will be available to Guinean health authorities to raise public awareness on this public health issue and implement control and prevention measures to limit the impact of intestinal parasitic infections

Повний текст джерелаDigestive protozoan infections are a major cause of morbidity, malnutrition and mortality worldwide. However, the biology of some enteric protozoa as Blastocystis is not well known and these microorganisms remain still neglected by the health authorities. Briefly, this parasite colonizes the intestinal tract of humans and various animals. Its main mode of transmission is the fecal-oral route and its prevalence can exceed 50% in developing countries. It exhibits a large genetic diversity with 17 subtypes (STs) identified to date. Recent data suggest that infection with Blastocystis is associated with a variety of gastrointestinal disorders and urticaria. As part of my thesis, epidemiological studies have been conducted in different countries (Lebanon, Senegal, France) to determine the prevalence of this parasite in the human population and identify risk factors for infection. In parallel, through a survey in French zoos, animal reservoirs of zoonotic transmission of Blastocystis have been proposed. Moreover, mechanisms involved in the colonization of the host by the parasite were studied.As part of, epidemiological, the parasite was identified in faecal samples by real-time PCR and the resulting amplicon was sequenced for subtyping. The first study conducted in Lebanon in the Tripoli area showed a prevalence of 19% in the general population but this prevalence reached 60% in a population of school children living in the same region. A prevalence of 100% was obtained in a cohort of Senegalese children. The high prevalence observed in these countries can be explained by poor hygiene conditions in connection with the faecal peril. In terms of distribution of STs, the ST3 was predominant in both countries followed by ST1 and ST2. In a multicenter study conducted in France, an overall prevalence of 18.3% was obtained with a predominance of ST3, followed by ST1, ST2 and ST4. This distribution is quite similar to that observed in most European countries. In the French study, parasite prevalence was significantly higher in summer than in winter. Other variables such as a recent trip and age have been identified as risk factors for transmission of the parasite. The contact with animals may represent another risk factor because of the zoonotic potential of the parasite. In a large epidemiological study conducted in two French zoos and including over 160 animal species, the overall prevalence of Blastocystis exceeds 30% with significant variations between animal groups. By comparing the distribution of STs between humans and different groups of animals, primates, artiodactyls (cattle and pigs) and birds represent major potential reservoirs of infection for humans.An association between infection with Blastocystis and appendicitis was demonstrated in a child in Morocco confirming the pathogenicity and invasive and inflammatory potential of the parasite. In addition, 26 other family members presented digestive symptoms suggesting waterborne outbreak of blastocystosis. The hypothesis of a relationship between Blastocystis ST and pathogenicity was suggested hence the interest of a comparative genomics study to identify virulence factors that may be present or absent for some STs. No difference was found between the ST4 genome sequenced during my thesis and the ST7 genome available in the database while these STs have different virulence in vitro. Finally, the unknown impact of colonization by Blastocystis on the composition of the human intestinal microbiota was evaluated. The compositions of the bacterial microbiota of 96 patients infected or not by Blastocystis were obtained by high-throughput sequencing and compared. A higher bacterial diversity was found in colonized patients compared to non-infected patients. These data suggest that colonization by Blastocystis would not be associated with dysbiosis generally observed in intestinal infectious diseases but rather to a healthy intestinal microbiota

Повний текст джерелаBlastocystis sp. is an anaerobic parasitic protozoa found in the digestive tract of humans and numerous animals. To date, it is the most common intestinal parasite found in human feces with worldwide distribution. Seventeen subtypes (ST1-ST17) have been described based on the comparison of SSU rRNA gene sequences. Blastocystis infection is associated with various gastrointestinal disorders and many studies suggest a correlation between Blastocystis STs and pathogenicity. My work was developed on three different topics. The first concerned the prevalence and the genetic biodiversity of the parasite in human populations. Epidemiological studies were conducted in France and Lebanon but also in Africa by performing the first survey of this parasite in Senegal. Subtyping of the isolates was performed by real-time PCR targeting a domain of the SSU rRNA gene followed by direct sequencing of the PCR product. In Lebanon, the prevalence of Blastocystis reached 20% in the general population and we demonstrated a correlation between ST1 infection and the presence of symptoms. In the same country, this prevalence was 60% in schoolchildren and patients presenting gastrointestinal symptoms. Strikingly, the prevalence of Blastocystis in a population of one hundred children living in a rural area reached 100% in Senegal and more than half of the infected children by the parasite presented gastrointestinal disorders. These latter studies highlighted the socioeconomic impact of blastocystosis in developing countries with poor hygiene sanitation. In France, a large-scale molecular epidemiological study was performed including patients presenting or not gastrointestinal symptoms. Stool samples were collected during winter and summer in 11 hospitals spread all over the French territory. We observed a high prevalence of Blastocystis in the french population with an average of 18.2% and the predominance of ST3 followed by ST1, ST4 and ST2 as in numerous countries. We also identified seasonal variations since the average prevalence of the parasite is 13.6% in winter and 23.1% in summer. The second topic focused on the identification of the risk factors of Blastocystis transmission to humans. We searched this parasite in bovid and human stools as well as in drinking water samples consumed by bovids and breeders in a limited geographic area of North-Lebanon. 30% of human samples, 69% of water samples and 80% of bovid samples were positive for the parasite. Interestingly ST3 is predominant in human and water samples followed by ST1, ST2 and ST4. ST10 and ST14 were predominant in bovid but both STs are lacking in human and water samples. To explain the lack of ST10 and ST14 in human and water samples, we suggested a transmission of these STs occurring through direct contact between bovid and / or the absence of transmissible cystic forms of these STs. Furthermore, this parasite was searched in the stools of numerous animal groups in the zoo of La Palmyre in France. We showed that nearly 40% of the analyzed stools were positive for Blastocystis and identified new reservoirs of human infections in carnivores. The prevalence of the parasite reached 60% in primates in which the identified ST1 to ST5 are identical to those observed in humans confirming the limited host specificity of these STs. In another study, we showed that the prevalence of Blastocystis was of only 3.5% in a population of one hundred dogs in France suggesting that this pet is not a natural host of Blastocystis. Finally, to clarify the pathogenicity of this parasite, the third topic highlighted the invasive character of Blastocystis observed in a case of appendicular peritonitis in a 9-year old girl returning from Morocco. Only Blastocystis was detected in stools, appendix, peritoneal liquid and Douglas pouch of the patient. Interestingly, simultaneous gastroenteritis occurred in 26 members of the child’s family suggested an outbreak with contaminated water as probable origin

Повний текст джерелаThe diagnosis of deep-seated Candida infections is difficult because bloodstream cultures are often negative. The sensitivity of other diagnostic methods such as mannan (Mn) antigenemia, IgM, total anti-Candida antibodies, procalcitonin and PCR were evaluated. Mn and IgM have a specificity of 100% and detect infected patients but lack sensitivity. Mn would be more sensitive than the serum PCR, but these results warrant confirmation. Procalcitonin >0,75 ng/ml differentiate fungal and bacterial infections from viral ones. During a 2-year study of the patients of the intensive care unit of the Versailles hospital, index of colonization (IC), defined as the ratio of Candida sp. Colonized anatomical sites / tested sites, and the serological tests mentioned above were performed. Only IC had a 100% sensitivity in surgical patients. Then, we explored the epidemiology of C. Albicans among these patients using 3 polymorphic microsatellite markers and we compared the results with a study already performed at Créteil hospital. If the C. Albicans genotype's distribution had been different, that could have resulted from a nosocomial transmission or to the fact that the populations of patients were different. The patients harboured their own isolate whatever the anatomical site sampled and kept it over the study period. This confirms that there was no crossed transmission. Some genotypes were more frequent due to the fact that C. Albicans is clonal. The populations of the 2 hospitals are similar using 3 statistical tests : " genic differentiation ", " genotypic differentiation " and factorial correspondence analysis. To study the epidemiology of C. Glabrata, the second leading yeast species in intensive care units, three polymorphic microsatellite markers were characterized
