Mycoplasma gallisepticum (MG) causes infectious sinusitis in turkeys, and is commonly associated with Escherichia coli. The objective of this study was to develop in turkeys an experimental model for infectious sinusitis. Two hundred and fifty male turkeys of Nicholas breed (Aviagen®) were divided into negative control group and challenged, animals were housed until 42 days old. The birds were inoculated in the first day of age with the MG vaccine (F-VAX ® Schering Plough) and on day 21 with E. coli. We analyzed the mortality, clinical signs and lesions in air sacs, liver and heart. The results showed that the vaccine against Mycoplasma gallisepticum (MG-F) is pathogenic for turkeys and that the experiment was able to simulate natural infection with MG and E. coli. |
