Emergence of neural angiostrongyliasis in eastern Australia

Abstract

Despite an apparent increase in cases of angiostrongyliasis in humans and animals in Australia, the epidemiology of infection with the two species of Angiostrongylus that co-exist in this country, namely A. cantonensis and A. mackerrasae, is poorly understood. This knowledge gap is particularly important with respect to A. mackerrasae, a species evidently native to Australia, as its ability to cause disease in humans is unknown. Likewise, there is little information on the roles of native and introduced species of rodents and molluscs as hosts of Angiostrongylus species in Australia. This review focuses on the gaps in the knowledge about the two species, highlighting the need for epidemiological and pathogenesis studies on the native lungworm A. mackerrasae.
