Environmental and anthropogenic changes are expected to promote emergence spread of pathogens worldwide. Since 2013, human urogenital schistosomiasis is established in Corsica island (France). Schistosomiasis a parasitic disease affecting both humans animals. The parasite involved the Corsican outbreak hybrid form between Schistosoma haematobium, parasite, bovis, livestock parasite. S. bovis has been detected few decades ago raising questions whether hybridization occurred if animals could...

Giardia duodenalis (syn. G. lamblia, intestinalis) is the protozoan parasite responsible for giardiasis, most common and widely spread intestinal parasitic disease worldwide, affecting both humans animals. After cysts ingestion (through either contaminated food or water), excysts in upper tract to release replicating trophozoites that are production of symptoms. In gut, cohabits with host's microbiota, several studies have revealed importance this gut ecosystem and/or some probiotic bacteria...

ABSTRACT Primates are regularly infected by fungal organisms identified as Pneumocystis carinii . They constitute a valuable population for the confirmation of P. host specificity. In this study, presence was assessed direct examination and nested PCR at mitochondrial large subunit (mtLSU) rRNA dihydropteroate synthetase (DHPS) genes in 98 lung tissue samples from captive or wild nonhuman primates. Fifty-nine air corresponding to environment different primate species zoological parks were...

Bovine leukemia virus (BLV), an oncovirus related to human T-cell type I, causes a B-cell lymphoproliferative syndrome in cattle, leading inversion of the T-cell/B-cell ratio and, more rarely, lymphosarcoma. Sheep are highly sensitive BLV experimental infection and develop pathologies similar those cattle 90% cases. tropism for B cells has been well documented, but other cell populations may also be involved BLV-induced syndrome. We thus looked provirus leukocyte sheep by using PCR. found...

Methods Faecal samples were collected from 414 pet 425 at 20 sites during 2017–2018 analysed by coproscopy. included specimens animals both genders various breeds ages a...

Giardiasis, a widespread intestinal parasitosis affecting humans and animals, is growing concern due to the emergence of drug-resistant strains G. intestinalis. Probiotics offer promising alternative for preventing treating giardiasis. Recent studies have shown that probiotic Lactobacillus johnsonii CNCM I-4884 inhibits intestinalis growth both in vitro vivo. This protective effect largely mediated by bile salt hydrolase (BSH) enzymes, which convert conjugated acids (BAs) into free forms are...

Contexte : Le pigeon (Columba livia) est une espèce d’oiseau domestique qui entre fréquemment en contact avec les humains. Les pigeons hébergent et disséminent de nombreux pathogènes zoonotiques, notamment des parasites apicomplexes du genre Cryptosporidium, un parasite protiste commun vertébrés. Ces dernières années, populations ont augmenté dans zones urbaines périurbaines, ce peut constituer risque pour la santé publique. Objectif Une revue systématique a été réalisée examiner présence...

Giardia duodenalis is a protozoan parasite responsible for giardiasis, disease characterized by intestinal malabsorption, diarrhea and abdominal pain in large number of mammal species. Giardiasis one the most common parasitic diseases world thus high veterinary, public health concern. It well-established that some probiotic bacteria may confer protection against this vitro vivo we recently documented implication bile-salt hydrolase (BSH)-like activities from strain La1 Lactobacillus...

Cryptosporidium is an obligate intracellular protist parasite infecting a wide range of vertebrate hosts and causes significant intestinal disease in both animals humans, as some species are zoonotic. Cattle especially calves have been identified one the most common reservoirs this protist. However, little known about genetics regions France. The aim study was to detect isolate spp. faecal samples from naturally infected pre-weaned (≤45 days-old) A total 35 diarrhoeic calf were collected 26...

The probiotic strain Lactobacillus johnsonii CNCM I-4884 exhibits anti-Giardia activity in vitro and vivo a murine model of giardiasis. aim this study was the identification characterization potential L. I-4884, as well its safety assessment. This originally classified gasseri based on 16S gene sequence analysis. Whole genome sequencing led to reclassification johnsonii. A genome-wide search for biosynthetic pathways revealed high degree auxotrophy, balanced by large transport catabolic...

Abstract Cryptosporidium spp. remain a major cause of waterborne diarrhea and illness in developing countries represent significant burden to farmers worldwide. parvum virus 1 (CSpV1), the genus Cryspovirus , was first reported be present cytoplasm C. 1997. Full-length genome sequences have been obtained from Iowa (Iowa), Kansas (KSU) China. We aimed at characterizing CSpV1 France used sequence analysis isolates explore whether diversity varies over time, with geographical sampling location,...

We are currently witnessing the endemization of urogenital schistosomiasis in southern Europe. The incriminated parasite is a hybrid between human and livestock parasite. Using an experimental evolutionary protocol, we created lines from pure strains both species. showed that host spectrum enlarged to after genomic introgression. also evidenced tropism parasites within changes some more virulent than parental strains. These results engage paradigm shift zoonotic transmission schistosomiasis.

Cryptosporidium parvum is an important apicomplexan parasite infecting ruminants and humans. We characterised the impact of C. infection on goat kid microbiome. was orally administered to parasite-naïve goats monitored for 26 days in faeces samples using IFA qPCR tests. Age-matched served as uninfected controls. A reduction bodyweight gain, diarrhoea, dehydration were observed infected compared Infection decreased bacterial diversity 5 post (dpi), but this parameter recovered at 15 dpi. The...

Gastrointestinal parasites are frequently encountered in captive non-human primates and infestation may have severe consequences on the animal's health status. Most of these also transmissible to humans. Nevertheless, little is known about prevalence monitoring modalities gastrointestinal parasitoses housed zoological institutions there currently no guidelines available for their detection identification. The objective this study was identify main that be observed France, as well develop a...
