Pathological and immunohistochemical studies on pneumonia/arthritis outbreak in a group of feedlot calves associated with infection by mycoplasma bovis [electronic reource].

Includes references.

Mycoplasma bovis (M.bovis) has been associated with many disease -entities in cattle including pneumonia arthritis syndrome of calves. Lately, there is an increase concern about the increasing prevalence of this pathogen in feedlot industry around the world. In this study, approximately five percent (11 calves) of 220 recently purchased feedlot calves (5-6 month of age) developed pneumonia that was associated with polyarthritis in 6 calves shortly after arrival. M.bovis was identified from the joint fluid swabs and/or serum of these calves using PCR and/or ELISA. A diagnosis of M.bovis associated pneumonia-arthritis disease had been made and the calves were treated with specific antibiotics.
