Mycobacterial Infections in Cats

Oct 29, 2009
Horne KS, Kunkle GA: Clinical outcome of cutaneous rapidly growing mycobacterial infections in cats in the south-eastern United States: a review of 10 cases (1996-2006), J Feline Med Surg 11:627, 2009.

In the United States, there have been very few case reports of cutaneous mycobacterial infections in cats. This study reviews 10 cases of cats with rapidly growing mycobacterial infections from the south-eastern United States. This condition is fairly uncommon and is a challenging condition to treat in cats due to a variable response rate to surgical debulking and aggressive antibiotic therapy. The majority of these cases were spayed female cats with the median age of 8 years. The majority of the cats presented with characteristic lesions in multiple locations that were subsequent to trauma. The most frequently cultured organism was Mycobacterium fortuitum. The cats were treated with a variety of antibiotics for a median of 12 months, and half of this number also underwent surgical debulking. Five out of the 10 cats treated reached clinical resolution and 5 cases did not. Those cases that achieved resolution required a median of 7 months of antibiotic treatment after diagnosis. With only half of the cases reaching resolution, one must consider a guarded prognosis in cases of feline rapidly growing mycobacterial infection in the south-eastern portion of the United States.
