First isolation of XXXX iowae in grey partridge flocks.

@entity9463 iowae, an occasional pathogen of @entity233 , was isolated for the first time from captive grey partridges (Perdix perdix). Clinical signs including respiratory and @entity1944 were seen in birds of all ages but mainly in those kept housed during rearing. Mortality rates averaged over 20% during the year. Treatment with antibiotics and antiparasitic drugs produced only a transient improvement in condition. The gross pathology findings included poor body growth, lack of development of the breast muscles, abnormalities in the keel development, and @entity79 . Some birds showed infraorbital @entity1244 with serous or fibrinous exudates and @entity6062 , while others presented serofibrinous airsacculitis and @entity381 . Laboratory investigations revealed pure cultures of M. iowae in the gut as well as sinus and air sacs. While other organisms such as coccidia, Trichomonas, @entity526 , @entity3168 , and Aspergillus spp. were detected, the similarity of the disease with that seen in @entity233 infected with M. iowae strongly suggests that this @entity9463 may be the primary pathogen here. The presence of M. iowae in game birds commonly released into the wild could have serious implications particularly in areas where industrial poultry farms are concentrated.
