Аннотация: Avian haemosporidians are globally distributed protozoan parasites transmitted to birds by dipteran vectors. The effects of haemosporidian infections are wide-ranging and generally manifest as negative impacts on avian survival and fitness. The study of avian haemosporidians has grown considerably over the past 20 years, such that inter-regional and global effects can be explored. However, considerable gaps in intra-regional studies remain; such studies are critical to broader assessments. In this study, we conducted a community survey of avian haemosporidians found in birds in Cát Tiên National Park, Vietnam. We quantified relative parasite abundance and host associations, and compared our results to data from nearby countries. We also assessed the broader geographic distributions of previously described haemosporidian lineages that we identified in our sample. We screened 320 birds and detected infections in just 28 (8.8%). Infections were either Haemoproteus (12, 3.8%) or Plasmodium (16, 5.0%); we detected no Leucocytozoon infections. We recovered 23 haemosporidian lineages, of which 19 are new, suggesting a high degree of parasite endemism. While our positive detection rate is considerably lower than expected, the high proportion of new versus previously described lineages highlights the need for a continued focus on localized studies to broaden our knowledge of intra- and inter-regional distributions as the field seeks the mechanisms underlying generalized patterns of parasite distribution.
