A 12‐year‐old neutered male domestic short‐haired cat was presented for rapid breathing, lethargy of two weeks duration and chronic weight loss. A diagnosis of toxoplasma‐induced pneumonia was made based on clinical signs, laboratory data, radiology, immunoglobulin M (IgM) serology and isolation of the organism from a lung aspirate. A passive haemagglutination test to measure immunoglobulin G (IgG) levels against toxoplasma was negative. The reliability of agglutination tests, to accurately diagnose an acute toxoplasma infection is questioned. In acute infections the use of an enzyme‐linked immunosorbent assay for IgM may be more specific.
