Abstract
Aim: Chicken infectious
anemia virus (CIAV) causes immunosuppression leading to serious
losses in chickens. Though CIAV has been reported in commercial
chickens from many countries of the world, no information is
available on CIAV from Grenada. This paper reports the result of a
serological survey of CIAV in layer and broiler chickens in
Grenada.
Materials and Methods: A total of 226 serum samples from
layers and 233 from broiler chickens were tested for CIAV
antibodies using CIAV/ELISA (IDEXX, West brook, Maine, USA).
Results: The results showed seroprevalence for CIAV in
layers at 92.9% (95% confidence interval, 89.55% to 96.25%) with a
parish seropositivity in the range 89.28% - 100%, whereas in
broilers overall seroprevalence was 58.3% (95% confidence
interval, 51.97% to 64.63%) with a range of 2.85%-92.85%,
according to parish.
Conclusion: A high prevalence of antibodies to CIAV in
commercial chickens indicates a CIAV contaminated environment in
Grenada. This in turn emphasizes the need for vaccination of
chickens against CIAV and further research on the impact of this
disease in Grenada.
Keywords: antibodies, Chicken infectious anemia virus,
chicken, ELISA, Grenada.
