Epizootic pneumonia in nutria.

This report highlights current knowledge regarding the aetiology, diagnosis and management of nutria (Myocastor coypus Molina 1792) with spontaneous infectious pneumonia. Bacteriological evidence supports the view that Streptococcus zooepidemicus could be the specific pathogen, although other bacteria were also isolated. Attempts at virus isolation were unsuccessful. Pneumonia has rapidly become established as one of the major, life-threatening bacterial diseases, ranking in importance with gastroenteritis infections.
