title: Isolation and characterization of Mycoplasma arginini from camels (Camelus dromedarius) with pneumonia.
abstract: Post-mortem examinations of 100 camels with pneumonic lesions were made at a local abattoir for Mycoplasma species. Sixteen isolates with indistinguishable biochemical and immunological characters were identified. The biochemical profile of these isolates showed that they were sensitive to digitonin, negative for urease production, glucose fermentation, and phosphatase activity but were positive for arginine hydrolysis. The identity of these isolates was further confirmed by disk growth inhibition test using a panel of specific antisera against selected reference Mycoplasma spp. Based on the biochemical profile and growth inhibition results, the camel isolates were identified as M. arginini. The pathological findings associated with M. arginini isolation consisted mostly of chronic interstitial pneumonia. The isolation rate of M. arginini from these specimens was 8.8%. These results suggest that the role of M. arginini in pneumonia in camels should be explored in greater detail.
