“…and three new lineages of Plasmodium spp. were reported by molecular technique using cytb gene [ 16 ]. Very high overall infection prevalence of 83.6% was registered for two sympatric sand hill crane populations seized in Texas [ 79 ].…”

“…Infected birds can rarely be captured by mist net due to their lessened mobility and activity and also due to the variation in vector abundance [ 1 ]. Additionally, several factors such as temporal and spatial influence, gender, age, immunological system, distinctive study approaches and various collected taxa may influence the prevalence rate in hematozoan parasites [ 15 , 16 , 81 ]. As the collection of samples for potential vectors in this study were performed near aquatic localities and rivers, the infection rate by Plasmodium and Leucocytozoon parasites were recorded as very low in contrast with Haemoproteus sampled throughout Iran, which may be attributed to the lack of available vectors in these regions.…”

“…Findings of similar studies also demonstrated the effectiveness of more sensitive PCR-based methods in comparison with the morphological detection of apicomplexan blood parasites [ 19 , 78 ].

“…Various haematophagous arthropods comprising mosquitoes (Culicidae), biting midges (Ceratopogonidae), Louse Flies (Hippoboscidae), and Black Flies (Simuliidae) are regarded as the main vectors of avian blood parasites [ 12 ]. Preceding studies have illustrated various infection rates between 0–100 percent in bird species around the world, based upon sampling area and detection procedures [ 13 – 16 ]. Previous morphological studies have proposed that the species of Haemoproteus are seemingly more host-specific than Plasmodium .…”

BackgroundThe mobility of birds across or between continents exposes them to numerous vectors that have the potential to transmit pathogens and spread them into new regions. A combination of rich species diversity of birds along with the small amount of molecular studies in Iran makes observing the blood parasite distribution in wild avian populations indispensable for further estimation and administration of blood parasites.Methodology/Principal findingsIn order to evaluate the infection rate and molecular context of avian blood parasites, bird samples were collected (passerine = 316 and non-passerine = 14) in eight provinces of northern Iran between June to September 2015 and 2016. All bird samples were examined for haematoprotozoan infections by morphological screening using light microscope and mtDNA cytb gene amplification. A total of 115 birds were positive for blood parasites by molecular approach (34.84% overall infection). The infection rate of Haemoproteus, Plasmodium, and Leucocytozoon were 33.03%, 1.21%, and 0.6%, respectively. Sequences analysis has detected 43 lineages in Iranian birds’ hosts. Lineages were attributed to three genera Haemoproteus (n = 37), Plasmodium (n = 4), and Leucocytozoon (n = 2), of which 23 lineages fully matched previously recorded sequences in GenBank and MalAvi data reciprocities. Five lineages of ACDUM1, ACDUM2, PARUS1, PYERY01, and SISKIN1 were detected in multiple hosts’ species from dissimilar families. In Bayesian tree, all sequences were clustered in three main monophyletic clades as Haemoproteus, Plasmodium, and Leucocytozoon genera.Conclusions/SignificanceAs the first study outlining the molecular detection of hematozoa of passerines from Iran, the current study has recorded 20 new lineages for three genera of Haemoproteus, Plasmodium, and Leucocytozoon. Additional investigations into these taxa in the avifauna for the other parts of Iran may provide extra information on blood parasites, hosts relationships and distribution patterns.

Pathogens can influence the success of invaders. The Enemy Release Hypothesis predicts invaders encounter reduced pathogen abundance and diversity, while the Novel Weapons Hypothesis predicts invaders carry novel pathogens that spill over to competitors. We tested these hypotheses using avian malaria (haemosporidian) infections in the invasive myna (Acridotheres tristis), which was introduced to southeastern Australia from India and was secondarily expanded to the eastern Australian coast. Mynas and native Australian birds were screened in the secondary introduction range for haemosporidians (Plasmodium and Haemoproteus spp.) and results were combined with published data from the myna's primary introduction and native ranges. We compared malaria prevalence and diversity across myna populations to test for Enemy Release and used phylogeographic analyses to test for exotic strains acting as Novel Weapons. Introduced mynas carried significantly lower parasite diversity than native mynas and significantly lower Haemoproteus prevalence than native Australian birds. Despite commonly infecting native species that directly co-occur with mynas, Haemoproteus spp. were only recorded in introduced mynas in the primary introduction range and were apparently lost during secondary expansion. In contrast, Plasmodium infections were common in all ranges and prevalence was significantly higher in both introduced and native mynas than in native Australian birds. Introduced mynas carried several exotic Plasmodium lineages that were shared with native mynas, some of which also infected native Australian birds and two of which are highly invasive in other bioregions. Our results suggest that introduced mynas may benefit through escape from Haemoproteus spp. while acting as important reservoirs for Plasmodium spp., some of which are known exotic lineages.
