A case of necrotizing fasciitis with septic shock in a cat caused by Acinetobacter baumannii.
A 4-year-old, neutered female, domestic shorthair cat admitted to the animal hospital for recurrent constipation presumed to be due to post-traumatic injuries, went into shock with signs including fever and ataxia followed by stupor. On the fifth day of hospitalization, the cat developed severe, diffuse oedema of the ventral abdomen with multifocal to coalescing erythematous areas and small vesicle formation. The results of bacteriological cultures of liver, spleen and kidney specimens led to the diagnosis of Acinetobacter baumannii sepsis. Histopathological findings of skin samples taken during necropsy showed an extensive epidermal and dermal necrosis with septic vasculitis and numerous intralesional gram-negative bacteria. Detection of the bla(OXA-51-like) gene specific for A. baumannii by PCR, performed retrospectively on samples of the deep layers of the skin, confirmed the presence of A. baumannii also in the cutaneous lesions. To our knowledge this is the first report of a necrotizing fasciitis with septic shock in a cat caused by A. baumannii.
