title: Retrospective diagnosis of Q fever ina  country abattoir by the use of specific IgM globulin estimations.
abstract: Twenty-two cases of pyrexial illness which occurred amongst workers in a country abattoir were investigated retrospectively for Q fever, brucellosis, and leptospirosis. In 18, the illness was shown to be Q fever. No diagnoses were established for the other four. The demonstration of circulating Q-fever-specific IgM globulin was instrumental in establishing the diagnosis in many of the cases.
