“…Among resident species sampled, Zosterops palpebrosus (Oriental white‐eye) was the most infected species with an assemblage of Haemoproteus lineages which appears to have diversified within the Zosteropidae family. Among migrants, Acrocephalus dumetorum was the most infected species with a diverse assemblage of Haemoproteus belopolskyi , which have a relatively low genetic distance from prevalent and widespread parasites of migrant Acrocephalids and Sylvids in Europe and African (Ishtiaq, ). This appears to be polymorphism within H. belopolyskyi clade.…”

We examined seasonal prevalence in avian haemosporidians (Plasmodium and Haemoproteus) in migrant and resident birds in western Himalaya, India. We investigated how infection with haemosporidians in avian hosts is associated with temporal changes in temperature and mosquito abundance along with host abundance and life‐history traits (body mass). Using molecular methods for parasite detection and sequencing partial cytochrome b gene, 12 Plasmodium and 27 Haemoproteus lineages were isolated. Our 1‐year study from December 2008 to December 2009 in tropical Himalayan foothills revealed a lack of seasonal variation in Plasmodium spp. prevalence in birds despite a strong correlation between mosquito abundance and temperature. The probability of infection with Plasmodium decreased with increase in temperature. Total parasite prevalence and specifically Plasmodium prevalence showed an increase with average avian body mass. In addition, total prevalence exhibited a U‐shaped relationship with avian host abundance. There was no difference in prevalence of Plasmodium spp. or Haemoproteus spp. across altitudes; parasite prevalence in high‐altitude locations was mainly driven by the seasonal migrants. One Haemoproteus lineage showed cross‐species infections between migrant and resident birds. This is the first molecular study in the tropical Himalayan bird community that emphasizes the importance of studying seasonal variation in parasite prevalence. Our study provides a basis for further evolutionary study on the epidemiology of avian malaria and spread of disease across Himalayan bird communities, which may not have been exposed to vectors and parasites throughout the year, with consequential implications to the risk of infection to naïve resident birds in high altitude.

“…Migratory behaviors are accompanied by the risk of spreading infectious diseases to new areas ( Altizer et al, 2011 ; Rappole et al, 2000 ; Satterfield et al, 2018 ). Many studies have suggested that migratory birds have an important role in the transmission of haemosporidian parasites among resident species by carrying new pathogens to a certain area ( de Angeli Dutra et al, 2021 ; Ishtiaq, 2017 ; Ishtiaq and Renner, 2020 ; Murata, 2007 ; Ramey et al, 2015 ; Waldenström et al, 2002 ). Meanwhile, some studies suggest a reduced introduction of new pathogens due to migratory species because of limitations in local host assemblage of co-transported parasites (e.g.…”

“…There is also a trade-off between the risk of infection and risk of migration which may ultimately lead to modifications and adaptations of migratory routes ( Clark et al, 2016 ; Mendes et al, 2005 ; Sorensen et al, 2019 ; Waldenström et al, 2002 ). Such global patterns in parasite distribution can be used to reveal possible locations of transmission ( Inumaru et al, 2017 ; Ishtiaq, 2017 ; Ishtiaq et al, 2007 ; Valkiūnas, 2005 ; Waldenström et al, 2002 ).…”

Migratory birds are important carriers of pathogens such as viruses, bacteria and protozoa. Avian haemosporidia have been detected from many wild birds of Japan, but the infection status of migratory birds and transmission area are still largely unknown. Gallinago snipes are long-distance migratory shorebirds, and five species migrate to or through Japan, including Latham's snipe which is near threatened. Haemosporidian parasites in four snipe species were investigated to understand the role of migratory birds in the transmission of avian haemosporidia. Namely, this study aimed: i) to investigate differences in parasite prevalence and related factors explaining infection likelihood among these migratory species, ii) to explore the diversity in haemosporidian lineages and possible transmission areas, and iii) to assess the possibility of morphological effects of infection. Blood samples were collected from snipes caught in central and southwest Japan during migration. Parasites cyt b gene DNA were detected via PCR-based testing, and detected lineages were phylogenetically analyzed. Additionally, factors related to prevalence and morphological effects of infection were statistically tested. 383 birds from four Gallinago snipe species were caught, showing higher overall prevalence of avian haemosporidia (17.8 %) than reported in other wader species in previous studies. This high infection rate is presumably due to increased contact with vector insects, resultant of environmental preferences. The prevalence of Plasmodium spp. Was higher in Swinhoe's snipes, while Haemoproteus spp. Was higher in Latham's snipes. These differences are thought to be related to ecological factors including habitat use, distribution and migratory route. Six lineages detected from juveniles indicate transmission between the breeding and sampling area. Contrary to expectations, a direct link between morphological features and haemosporidian parasite infection were not detected. These findings provide valuable information for conservation of this endangered migratory bird group. Further studies linking biological and parasitological research are anticipated to contribute to conservational actions.

“…Thus, removing the above problems in the present study. Very few studies on avian haemosporidians have been performed in India utilizing the MalAvi database that were not either confined to a single bird species (Ishtiaq 2017) or particular mountain ranges (Gupta et al 2019).…”

We examined the Avian haemosporidians (Plasmodium and Haemoproteus) status in selected bird groups (Old world Flycatchers, Warblers, Babblers, and Thrushes) of India and their phylogenetic relationships with other known lineages of the world. The use of common genetic markers with information on the geographic distribution of parasite and host samples makes the data of avian haemosporidians genetic studies more comparable and infection source surveillance ready. The prevalence of Avian haemosporidians, in above bird groups from northern, eastern, and southern parts of India and the phylogenetic genetic analysis of genetic lineages was carried out at world level to know the possible source of infection. The MCC tree revealed six Haemosporidian lineages in which one was common (H_MSP01) and five were unique (H_CYOPOL01, H_CHD01, H_CYORUB01, H_EUMTHA01, and P_GEOCIT01). The avian host richness Index was 2.0852. 9.9%, prevalence of Haemosporidian infection was found in 111 DNA samples belonging to 6 host species. The Haemoproteus prevalence was found to be 90.9% across five host species (Phylloscopus trochiloides, Cyornis poliogenys, C. hainanus dialilaemus, C. rubeculoides, Eumiyas thalassinus) and Plasmodium prevalence was 9.0% in Geokichla citrina. The spatial phylogeny map showed possible source populations of hosts having H. pallidus lineages COLL2 and PFC1 infections in parts of Africa, Europe, North America, Malaysia, and Philippines. The Plasmodium lineage (P_GEOCIT01) showed a weak (93.89%) similarity with PADOM16 in Egypt. The statistical analysis suggested that the haemosporidians host species distribution range was directly and significantly associated with the altitude, minimum temperature, and relative humidity. H_MSP01 distribution was in accordance with H. pallidus having a wide geographic and host range.
