Plain-English summary

An 11-month-old Egyptian Mau-cross cat was brought to the vet for painful joints and skin issues. After tests, the vet found that the cat had erosive polyarthritis, which is inflammation of the joints that can be caused by infections. They discovered Mycoplasma gateae bacteria in the joint fluid and treated the cat with Enrofloxacin, which quickly improved his condition. Unfortunately, two months later, the cat had to be euthanized due to severe kidney disease and anemia, likely linked to the mycoplasma infection.

Abstract

Erosive polyarthritis was diagnosed in an 11-month-old neutered male Egyptian Mau-cross cat with concurrent glucocorticoid-responsive dermatitis. Clinical signs, synovial fluid analysis, serological tests and radiographic appearance could not differentiate between immune-mediated and infective arthritis. Mycoplasma gateae was isolated by strictly anaerobic culture of the synovial fluid. Treatment with Enrofloxacin led to a rapid improvement of the cat's condition. Two months later the cat was euthanased because of severe glomerulonephritis and direct Coombs' test positive anaemia, possibly caused by mycoplasma infection. M gateae could not be isolated at post-mortem examination.
