Asthma associated with a circulating IgG antibody to Calliphora maggots

Abstract
Summary: The case report of an angler with delayed onset asthma, following fishing with Calliphora (Blue Bottle) maggots, is presented. The investigations showed that the symptoms were associated with the presence of a circulating IgG antibody to a crude water soluble maggot extract. The patient progressed to develop symptoms suggestive of immune complex disease.
