The experimental study on susceptibility of common European songbirds to Plasmodium elongatum (lineage pGRW6), a widespread avian malaria parasite

Plasmodium elongatum (cytochrome b lineage pGRW6) is a widespread avian malaria parasite, often causing severe disease in non-adapted hosts. This parasite lineage is of global distribution however, its virulence ...

We examined avian Haemosporidia cytochrome b gene among terrestrial birds on Gorgona Island National Park, Colombia. Three Haemoproteus haplotype groups found on Gorgona Island have a higher genetic similarity to Haemoproteus found in the eastern tropical Pacific than those documented in Africa, Asia, Europe and Oceania. Two of the haplotype groups on the island are generalists in terms of infecting multiple hosts and their wide geographical distribution within the eastern tropical Pacific region, a third Haemoproteus haplogroup appears endemic to Gorgona Island. The overall prevalence of haemosporidian parasites is 57,9% ...

Abstract Avian malaria is a mosquito-borne parasitic disease of birds caused by protists of the genera Plasmodium, most notably Plasmodium relictum. This disease has been identified as a primary cause of the drastic decline and extinctions of birds, in particular Hawaiian honeycreepers (Drepanidinae), where rates of mortality may exceed 90%. We formulate an epizootiological model of the transmission dynamics of avian malaria between populations of bird hosts and mosquito vectors using a system of compartmental ordinary differential equations. We derive the basic reproduction number as well as criteria for the exis...

ute;M Abstract Avian malaria is a widespread infection caused by parasites from the Order Haemosporida. Indeed, Neotropical swifts are interesting models for host-parasite coevolution studies due to their unique life history that may allow them to escape parasitism. Considering this, we evaluated haemosporidians from Neotropical swifts. We collected blood and prepared smears from 277 individuals from waterfalls in Brazil. Despite low parasitemia or absence of parasites detected by microscopy haemosporidian infection was detected in 44 swifts (15.8%) using a screening PCR that amplifies a 154-nucleotide segment of ...

sch S Abstract Avian haemosporidian parasites are particularly diverse and widespread. To date, more than 3,000 distinct cytochrome b lineages have been recorded, of which some present extremely wide geographical distributions, even including multiple continents. Whether these isolates represent one or several cryptic species remains unknown. Here we carried out a case study of SISKIN1, a common haemosporidian parasite lineage belonging to the morphologically described species Haemoproteus tartakovskyi. To shed light on its evolutionary origin, we investigated the divergence between SISKIN1 isolates obtained from ...

Abstract Mosquitoes (Diptera: Culicidae) are the most significant arthropods of medical importance because of the burden of diseases, such as malaria, encephalitis and filariasis, which are caused by pathogens and parasites they transmit to humans. In 2007, the most recently published checklist of Iranian mosquitoes included 64 species representing seven genera. Public databases were searched to the end of August 2018 for publications concerning the diseases in Iran caused by mosquito-borne pathogens. Pertinent information was extracted and analyzed, and the checklist of Iranian mosquitoes was updated. Six arbovir...
