background: parasites affect the health and productivity of birds. haemoproteus columbae occurs in pigeons widely in tropical and subtropical regions. the present investigation was concentrated on the prevalence of h. columbae and rate of para-sitemia in domestic pigeons in southwest of iran. methods: pigeons regimented in three groups, less than six months old, between six and twenty four mont...

Several health problems can affect pigeons but parasitic infections play a major role. The genus Haemoproteus includes a large number of intracellular protozoan parasites. A total of 103 pigeons were captured from different localities of Qena Governorate from March 2013 to April 2014, blood films were obtained, fixed, stained and examined microscopically. Lungs and liver were also examined hist...

A cross-sectional survey was performed on domestic pigeons (Columba liviadomestica) to evaluate the prevalence of Haemoproteus columbae and Trichomonas gallinae in West Azerbaijan Province, northwest of Iran between July 2015 and September 2016. Five hundred and sixty oropharyngeal swab smears were examined, 297 (53%) of which were identified to be positive for T. gallinae. Also, the results ob...

BACKGROUND Parasites affect the health and productivity of birds. Haemoproteus columbae occurs in pigeons widely in tropical and subtropical regions. The present investigation was concentrated on the prevalence of H. columbae and rate of parasitemia in domestic pigeons in southwest of Iran. METHODS Pigeons regimented in three groups, less than six months old, between six and twenty four month...

Mature and immature stages of Haemoproteus columbae gametocytes, an avian haemosporidian protozoan parasite were found in 75% of blood smears prepared from 30 healthy domestic pigeons in Sebele location, Gaborone, Botswana. Parenteral administration of an immuno-suppressive dose of dexamethasone, lowered the level of parasitaemia, the packed cell volume and the heterophil:lymphocyte ratio in th...

as there is no data available on parasite infection of pigeons (columba livia) in the region, the present study was carried out on domestic pigeons in mashhad city in the north-east of iran. three hundred specimens were examined for the presence of ecto and endoparasites. a total of 300 pigeons, %21.6(n=65) and %15.3(n=46) were infected with nematodes and cestodes respectively whereas no tremat...

The prevalence and intensity of blood parasites in three species of wild doves were studied in the municipality of Junqueirópolis, in the western region of the State of São Paulo, Brazil. Three species of doves were surveyed: 331 specimens of Zenaida auriculata Des Murs, 1847, 62 specimens of Columbina talpacoti Temminck, 1811 and 57 specimens of Scardafella squammata Lesson, 1831. Haemoproteus...

Background: Haemoproteus columbae is widely distributed in tropical and subtropical regions, causing pseudomalaria in pigeons. Aims: The current study aimed to characterize the phylogenetic position of H. columbae in pigeons in Sharkia province, Egypt, based on partial sequencing of the cytb gene as the conserved regions. The “DNA barcode” of the cytb gene helps in designing primers that can be...
