“…neoformanns in the faecal matter of all the species of avians except pigeons to establish the ecology of the pathogen. Nevertheless, the credit goes to Emmons (1955) (Pal and Baxter, 1985;Pal et al, 1990 andSasaki et al, 1999). Furthermore, Pal's medium has shown excellent results for studying the genetic crossing experiment.…”

This is the first report of a disseminated mycobacteriosis caused by Mycobacterium kansasii in a reindeer (Rangifer tarandus). A two-year-old female reindeer with a history of lethargy and dyspnea was diagnosed with multiple pulmonary abscesses radiographically. At necropsy the animal had severe diffuse granulomatous pneumonia and pleuritis with severe multifocal granulomatous m yocarditis, lymphadenitis, nephritis, esophagitis, enteritis, and thyroiditis. Impression smears of necrotic debris from granulomas contained numerous acid-fast bacilli. M. kansasii was cultured from pulmonary, renal, hepatic, and lymph node sections. M. kansasii is a slow-growing photochromogenic non-tuberculous mycobacterial species that causes disease in severely immunocompromised individuals (3,4,9). Due to the popularity of reindeer as animals for exhibition in children's zoos, petting zoos, and holiday exhibitions, diagnosis of Mycobacterium kansasii in a reindeer is a significant public health concern.

A total of 887 pellets of different avifauna were screened for the presence of Cryptococcus neoformans. One hundred and six of 887 samples (12%) yielded Cr. neoformans in culture. The report on the isolation of Cr. neoformans from the pellets of the crow appears to be new and of greater significance because of the ubiquitous prevalence of this bird in India. The prevalence of both MAT a and MAT alpha mating types were recorded. The serotype D was predominant over serotype A. The findings of the present study reveal the growing diverse ecological niche of Cr. neoformans in a the pellets of various avifauna in India.
