Ultra-structure of blood cells and molecular characteristics of Haemoproteus sp. in Blyth’s hawk eagle

Abstract Haemoproteus was detected in the blood smear of an adult female Blyth’s hawk eagle which was submitted to the Kasetsart University Raptor Rehabilitation Unit. The morphology and ultra-structure of leukocytes and gamonts of Haemoproteus were described. The gamont’s cytoplasm contained scattered brown to black pigment granules with a mean of 12 granules per parasite. Monocytes played a major role in the elimination of the gamonts. According to the annotated checklist of the avian Haemoproteidae, the Haemoproteus in this eagle was closely related to Haemoproteus buteonis. The phylogeny of mitochondrial cytochrome b genes of Haemoproteus revealed 96.5 and 97.6 % similarity in identity with the Haemoproteus from two collared scops owls and seven barn owls (99.3 to 99.8 % similarity) from Thailand, and they were also similar to the Haemoproteus isolated from other reported avian species in Southeast Asia. The eagle was clinically healthy without any treatment. It was free from Haemoproteus by light microscopy and molecular technique 8 months later and was released in Krungching Waterfall, Khao Luang National Park, southern Thailand.

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 ...

ABSTRACTMosquito vectors play a crucial role in the distribution of avianPlasmodium parasites worldwide. At northern latitudes, where climate warming is most pronounced, there are questions about possible changes in the abundance and distribution ofPlasmodium parasites, their vectors, and their impacts to avian hosts. To better understand the transmission ofPlasmodium among local birds and to gather baseline data on potential vectors, we sampled a total of 3,909 mosquitoes from three locations in south ‐central Alaska during the summer of 2016. We screened mosquitoes for the presence ofPlasmodium parasites using molecula...

Conclusion: Age and sampling localities do not influence the infection rate of Haemoproteus spp. from the eastern provinces of Iran. The relative high infection of avian haematozoa revealed this region might provide suitable sites for future studies on these parasites and the relationship with their hosts and vectors.

Abstract A molecular surveillance of haemosporidian parasites from 19,521 Culex pipiens (L.) (Diptera: Culicidae) from Kuwait detected 2 pools with a unique Haemoproteus (Haemoproteus) sp. (Haemospororida: Haemoproteidae) most likely parasitizing columbiform birds and probably represented contaminated blood meals or aborted infections in mosquitoes. Haemoproteus spp. have been previously reported in Kuwait based on microscopic examination of avian blood smears. I report on molecular detection and subgenus level identification of a novel Haemoproteus (Haemoproteus) sp. Mosquitoes are not known as vectors of Haemopr...

The objectives of this study were to determine the prevalence of pigeon fly, identify its possible phoretic association with mites, and determine the prevalence of hemoproteid parasites in domestic pigeons (Columba livia domestica) in Kermanshah province, west of Iran. From May 2015 to May 2016, 16 colonies of domestic pigeons were investigated. In case of infestation, the flies were fixed in ethanol containing glycerin and then placed in potassium hydroxide. The flies were identified based on morphological characteristics. The masses suspected to contain mites were removed from the body surfaces of flies by centrifugation...

Outlaw, Gabriel L. Hamer The unicellular blood parasites in the order Haemosporida are highly diverse, infect many vertebrates, are responsible for a large disease burden among humans and animals, and have reemerged as an important model system to understand the evolutionary and ecological dynamics of host-parasite interactions. The phylogenetics and systematics of Haemosporida are limited by poor sampling of different vertebra...

Mepron, a thick liquid antimicrobial drug used to treat Babesia and malaria, as well as a fungal infection called Pneumocystitis carinii. In 2011, the United Kingdom stopped requiring that dogs brought into the country be inspected for ticks. Earlier this year, several dogs tested positive for babesia, a malaria-like disease transmitted to ticks that previously had only been found in foreign. These dogs had never left the U.K. While babesiosis is a new worry to U.K. dog owners, it's been a threat to human beings for years -- it just hasn't become a health-scare-of-the-week like Zika, West Nile, avian and swine flu.
