Mycobacterium avium subsp. hominissuis menigoencephalitis in a cat

Vet Microbiol. 2017 May;204:43-45. doi: 10.1016/j.vetmic.2017.04.008. Epub 2017 Apr 15.


A 33-month old, neutered female Abyssinian cat died. The cat had sudden onset of widespread neurologic signs about half a year after birth. Mycobacterium avium subsp. hominissuis (MAH) group was isolated and identified from the brain of a cat affected with pyogranulomatous meningoencephalitis. The central nervous system (CNS) was involved in the disseminated MAH infection. MAH infection should be considered in cats with neurologic signs in regard to zoonotic aspects. Comparatively, this is a first case of MAH infection observed in the brain in either humans or animals.
