Response of Domestic Pigeons (Columba livia) to Experimental Infection with Chicken Isolate of Infectious Bursal Disease (IBD) Virus
The susceptibility of pigeons (Columba livia) to chicken isolate of infectious bursal disease (IBD) virus was investigated under arid zone condition. Thirty pigeons, 15 adults and 15 young ones were acquired from the Maiduguri Monday Market and some households in Maiduguri. The pigeons were divided into two groups thus: Group A, which is the experimental group and consisted of ten (10) adults and ten (10) young pigeons. Group B that served as the control group was made up of five (5) adults and five (5) young pigeons. Pigeons in group A were infected with 3 drops of IBD virus inoculum orally while those in group B were given same quantity of normal saline per os. All the pigeons in groups A and B did not manifest any clinical sign throughout the period of the study. However, some of the serum samples from the infected group were positive for presence of precipitin antibody on day 7 and 14 PI, while all the samples became negative on 21 days PI. The study revealed that pigeons (young and adults) are resistant to experimental infection with chicken isolate of IBD virus. However, the birds seroconverted following exposure to the virus despite the absence of clinical signs. This showed that there was “virus take” following exposure of the species to IBD virus. The possible role of pigeons in the epidemiology of IBD in Nigeria need to be further investigated.
