Cloacal adenocarcinoma and mycobacteriosis in a White’s Tree Frog - case description

Mycobacterium fortuitum infection and adenocarcinoma were associated with cloacal prolapse in a White’s tree frog (Litoria caerulea). The disease was characterized by the presence of nodules in a cloacal mucous membrane. Bacteriological examination of the cloacal tissue revealed the presence of Enterococcus sp., E. coli and numerous acid-fast bacteria (AFB). The presence of AFB was confirmed by a Ziehl-Neelsen stain of the cloacal tissue and culture on the Löwenstein-Jensen medium. Post-mortem examination showed no changes typical of mycobacteriosis or neoplasia in other organs.
