Abstract:
Goat farming is getting momentum in uplifting socio-economic status of livestock farmers. However, they face the challenging respiratory affections quite often leading to economic losses. The present study places on record the association of pneumonia caused by Proteus mirabilis in goats of Chhattisgarh in central India. An overall 398 goats were screened for respiratory diseases in the three agroclimatic zones of Chhattisgarh through stratified random sampling and 212 samples including nasal swabs (85), tracheal swabs (15) lung swabs (56) and lung tissues (56) were collected from September 2019 to July 2022 from goats showing some signs of respiratory ailment/lesions. Out of 212 samples 92 bacterial isolates were obtained. Two (2.17%) isolate of Proteus mirabilis were identified using conventional, MALDI-TOF MS analysis and 16s rRNA gene sequencing. Phylogenetic analysis was done. Pathomorphology of pneumonic lungs revealed varying degrees of cranio-ventral consolidation, oedema and abscess formation. Histopathology of affected lungs showed areas of atelectasis, emphysema together with accumulation of polymorphonuclear cells delimited by a pyogenic membrane. This study shows that the opportunistic Proteus mirabilis could also result in respiratory infections of goats.
