Pullets of the Brazilian poultry industry are susceptible to outbreaks of infectious diseases with economic losses, mainly caused by Mycoplasma, Avibacterium paragallinarum and viruses affecting the respiratory tract. The objective of this study was to verify the involvement of A. paragallinarum in an outbreak of avian respiratory disease. Eighteen swabs from the infra-orbital sinuses were collected, six samples from broilers and twelve from hens with clinical signs. The samples were cultured in specific media for the agent and also tested with the molecular technique of Polymerase Chain Reaction (PCR). All samples cultured in specific media were negative; PCR revealed two samples (16.66%) as positive. The detection of A. paragallinarum by PCR in laying hens with clinical respiratory signs indicates that this bacterium is associated with the etiology of respiratory syndrome in poultry farms in the state of Pernambuco. |
