Seroprevalence of antibodies to astrovirus in chickens in Grenada, West Indies
2. Department of Preclinical Studies, Ecole Nationale Veterinaire De Toulouse, France (DVM students, on Internship Program at St. George's University Grenada).
Background and Aim: Chicken astroviruses (CAstV) are known to cause mild gastroenteritis, growth depression, and even mortality in poultry, especially in chickens, turkeys, and ducks. To the best our knowledge, there is no published information on CAstV in Grenada. This study was conducted to determine the prevalence of astrovirus in chickens in Grenada.
Materials and Methods: Blood samples from 366 indigenous chickens and 92 commercial chicken layers were collected from all parishes of the island and tested for antibodies against CAstV using commercial enzyme-linked immunosorbent assay.
Results: The seroprevalence of antibodies against astrovirus was 57.6% (95%, Confidence interval [CI]: 47.4-67.2) in commercial layers and 61.5% (95%, CI: 56.4-66.3) in indigenous chickens. The results show the presence of infection throughout the island.
Conclusion: The results show the infection with CAstV in approximately half of the chicken population in Grenada. This is the first report on the prevalence of CAstV in chickens in Grenada and the Caribbean region. Keywords: Astrovirus, chicken astroviruses, chickens, Grenada, seroprevalence.
