Natural intestinal parasite infection in synanthropic migratory Barn Swallow, Hirundo rustica, in central Peninsular Malaysia.

Migratory birds are potential vectors transmitting zoonotic parasites, bacteria, and viruses that can significantly affect human health. Over 60 diseases have been identified to be associated with these birds. Given their close proximity to human habitation, the potential transmission of zoonotic diseases is a major concern for the public. In this study, we aimed to assess the prevalence of intestinal parasites in the droppings of the Barn Swallow, Hirundo rustica, a bird species that annually migrates to Malaysia. Eighty droppings from H. rustica were collected; 13.75% of the samples were found to be positive for various parasites, including Ascaridia galli (8.75%), Eimeria sp. (2.5%), Hymenolepis spp. (1.25%), and Toxocara spp. (1.25%). These findings offer valuable insights into the current prevalence of bird parasitic infections. They can serve as a crucial resource for implementing effective control measures, devising prevention strategies, and predicting future outbreaks of parasite infections transmitted by birds.
