| Summary: | Bats (Chiroptera) are one of the most successful and diverse of mammalian orders, with an estimated 1100 species worldwide. Due to protected species legislation, studies that focus upon bat endoparasites are limited. As such, many fundamental questions concerning bat-parasite relationships remain unanswered, including evolutionary aspects of such associations, hostparasite interactions and factors that may influence the composition of bat parasite communities. To further knowledge of bat parasitology, one hundred bats, that had either died of natural causes, or had been euthanized due to severity of injury, were acquired across Greater Manchester and Lancashire between September 2005 and September 2008. Molecular typing methods confirmed 93 specimens to be common pipistrelle (Pipistrellus pipistrellus), six to be soprano pipistrelle (P. pygmaeus) and one to be a whiskered bat (Myotis mystacinus). Development of PCR-based methodologies, coupled when possible with morphological analyses, confirmed the presence of the following microparasites (prevalence data in parenthesis): Babesia vesperuginis (23%), Trypanosoma spp (36%), Bartonella sp. (2%) and Eimeria sp. (20%), and the following macroparasites: Lecithodendrium linstowi (80.4%), Lecithodendrium spathulatum (19.6%), Prosthodendrium sp. (35.3%), Plagiorchis koreanus (29.4%) and Pycnoporus heteroporus (9.8%). Potential factors affecting the parasite community composition including host sex and age, season, year, geographic location and parasite co-infection are explored. The detection of Eimeria sp. would appear to be the first record of coccidia in British bats, and also the first global record of Eimeria sp. from the common pipistrelle. Phylogenetic analysis of bat-associated Bartonella sp. ITS region, clusters the isolate in a well supported clade with B. grahamii, B. elizabethae and B. queenslandensis, all known to infect rodents, in addition to B. grahamii and B. elizabethae being recognised human pathogens. The first molecular sequence data for L. ... |
