Abstract
Background: Hepatitis E virus (HEV) is transmitted by the fecal route, usually through contaminated water in humans and/or infected animals, especially pigs. The objective of this study was to evaluate the level of anti-HEV antibodies in a panel of pig sera and to identify HEV in pig feces in farms. Methodology: The presence of HEV antibodies was tested by an in-house ELISA and a commercial ELISA IDvet. HEV genome was assessed by nested RT-PCR, and then, genotype was identified by sequencing (MinION Nanopore technology). Results: In 2017-2019, the 43% seroprevalence found in Forest Guinea was significantly higher than the 7% found in the Lower region (p < 0.01). Presence of HEV genotype 3c was demonstrated during a secondary study in the Lower region (Conakry) in 2022. Conclusion: The presence of HEV-3c in pigs calls for an evaluation of seroprevalence in human populations and for a HEV genotype human circulation check. Contribution Heading: This study is the first report, to our knowledge, of seroprevalence and characterization of HEV infection in pigs in Guinea.
期刊介绍：
Vector-Borne and Zoonotic Diseases is an authoritative, peer-reviewed journal providing basic and applied research on diseases transmitted to humans by invertebrate vectors or non-human vertebrates. The Journal examines geographic, seasonal, and other risk factors that influence the transmission, diagnosis, management, and prevention of this group of infectious diseases, and identifies global trends that have the potential to result in major epidemics.
Vector-Borne and Zoonotic Diseases coverage includes:
-Ecology
-Entomology
-Epidemiology
-Infectious diseases
-Microbiology
-Parasitology
-Pathology
-Public health
-Tropical medicine
-Wildlife biology
-Bacterial, rickettsial, viral, and parasitic zoonoses
