Genotyping of Mycobacterium avium subsp. paratuberculosis (Map) is an indispensable tool for surveillance of this significant veterinary pathogen. For Map, multi-locus variable number tandem repeat analysis (MLVA) targeting mycobacterial interspersed repetitive units (MIRUs) and other variable number variable-number tandem repeats (VNTRs) was estab...
Rotaviruses are the most common infectious agents causing severe diarrheal diseases in young children globally. Three rare human rotavirus strains, two G3P[9] and one G3P[6], were detected in stool samples of children under 5 years of age hospitalized for gastroenteritis in Lebanon during the course of a surveillance study. Complete genomes of thes...
Visceral leishmaniasis (VL), the most severe form of the disease, is caused by Leishmania donovani in the Indian sub-continent (ISC). Whole genome sequencing studies revealed that two parasite populations exist in the ISC: a main population named the Core Group (CG) found mostly in the lowlands, and a new, genetically different subpopulation called...
The human mastadenovirus C (HAdV-C) cause respiratory infections in children. Homologous recombination was clearly involved in the molecular evolution of HAdV-A, B, and D, but little is known about the molecular evolution of HAdV-C. From 2000 to 2016, 201 HAdV-C strains were collected from nine provinces covering six administrative regions of mainl...
Chagas disease, caused by the parasite Trypanosoma cruzi, is one of the most neglected diseases in Latin America, being currently a global health problem. Its immunopathogenesis is still quite unknown. Moreover, there are important differences in pathogenicity between some different T. cruzi strains. For example, in mice, Y strain produces a high a...
Sheeppox and goatpox are two of the most important diseases associated with significant economic loss and impact on animal trade. In spite of the use of vaccines, outbreaks are being reported on several occasions. Therefore, deciphering the host specificity and virulence of sheeppox virus (SPPV) and goatpox virus (GTPV) is important in developing e...
Sensitive diagnostic techniques are needed for timely detection of malaria parasite and disease control. Molecular diagnostic techniques involving Polymerase chain reaction (PCR) with 18 s rRNA as a known diagnostic target with an overall sensitivity of 10 parasites per microliter is used as a gold standard. Till date, no attempt has been undertake...
Most human cases of cryptosporidiosis are caused by Cryptosporidium parvum or Cryptosporidium hominis. However, the number of recognised Cryptosporidium species, some of which are capable of infecting humans, is continuously increasing. Here we present three human cases infected with Cryptosporidium ditrichi, a recently described species in Apodemu...
Island bird populations and their obligate blood parasites are of interest for understanding the accumulation of biodiversity and the evolutionary relationship with their mainland congeners. We examined avian Haemosporidia cytochrome b gene among terrestrial birds on Gorgona Island National Park, Colombia. Three Haemoproteus haplotype groups found ...
Ancylostoma ceylanicum is a zoonotic hookworm, which mainly causes iron deficiency anemia (IDA) in humans and animals. Hookworm platelet inhibitor (HPI) has been isolated from adult Ancylostoma caninum and linked to the pathogenesis of hookworm associated intestinal hemorrhage and IDA. However, there is no available data about HPI from A. ceylanicu...
