Gastropod molluscs are used as intermediate hosts and rats of various species are definitive hosts of this parasite. In this study, we identified several environmental factors associated with the presence and abundance of terrestrial gastropods in an impoverished urban region in Brazil. We also found that body condition, age and presence of co-infection with other parasite species in urban<jats:italic>Rattus norvegicus<\/jats:italic>, as well as environmental factors were associated with the probability and intensity of<jats:italic>A. cantonensis<\/jats:italic>infection. The study area was also found to have a moderate prevalence of the nematode in rodents (33% of 168 individuals).
