babesia crassa n.sp. (sporozoa, babesiidae) of domestic sheep in iran.a large babesia sp., isolated from a sheep in iran, provided to be serologically and morphologically different from b, motasi and b. ovis. the parasite, designated b. crassa n. sp., is characterized by the frequent occurrence of four organisms in one erythrocyte, which is the result of quadruple division and, in other cases, of two successive binary divisions. parasited resulting from the first of two successive binary divisions are exceptionally broad. b. crassa appears to be of low pathogenici ...19817209943
piroplasms of domestic animals in the macedonia region of greece. 3. piroplasms of small ruminants.a study was carried out on piroplasms of small ruminants in the macedonia region of greece. during 1984-1985, 721 serum samples were collected from sheep in 49 localities and 487 from goats in 43 localities. blood smears were also prepared from 26 sheep and eight goats in 16 localities. the prevalence of positive ifa titres for sheep and goat sera, respectively, was: 24.6% and 0.6% for theileria ovis, 52.1% and 36.4% for babesia ovis, 10.5% and 4.2% for babesia motasi, 12.6% and 6.6% for babesia ...19968792581
determination of rhipicephalus spp. as vectors for babesia ovis in iran.the tick-borne diseases of livestock constitute a complex of several diseases with different etiological agents, such as protozoa, rickettsia, bacteria, and viruses. one problem discussed in protozoan infection is the determination and characterization of the transmitter agent. because many analyses were performed with the salivary gland smears using the methyl-green-pyronin staining method or the feulgen staining method, the transfer vector remains unanswered in some cases. the aim of this stud ...200717554562
[detection of babesia spp. dna in small mammals and ixodic ticks on the territory of north ural, west siberia and far east of russia].totally, 932 small mammals and 458 questing adult ixodes persulcatus from sverdlovsk and novosibirsk regions and khabarovsk territory, as well as 128 haemaphysalis japonica, 34 h. concinna and 29 dermacentor silvarum from khabarovsk territory were examined for the presence of babesia by nested pcr based on the 18s rrna gene. babesia microti dna was found in samples of small mammals from all the studied regions--in 36.2% of samples from sverdlovsk region, 5.3% of samples from novosibirsk region, ...201020886686
Babesia ovis as the main causative agent of sheep babesiosis in Iran.Babesiosis is a haemoparasitic disease with high economical losses in livestock industry worldwide. The early diagnosis and successful therapy of babesiosis belong to the key steps of control and health management of livestock. Ethanol-fixed blood samples of 400 sheep were analyzed for Babesia infection. Reverse line blot (RLB) was established specifically for Theileria lestoquardi, Theileria (China 1), Theileria (China 2), Theileria ovis, Theileria separata, Babesia ovis, Babesia motasi, Babesi ...201121975684
a study on ovine tick-borne hemoprotozoan parasites (theileria and babesia) in the east black sea region of this study, the frequency of theileria and babesia species was assessed via reverse line blotting and blood smear-based diagnostic methods in small ruminants. a total of 201 apparently healthy animals from 26 randomly selected herds located in 4 locations (artvin, giresun, gumushane, and tokat) of east black sea region of turkey were investigated for the blood protozoans. in a polymerase chain reaction (pcr), the hypervariable v4 region of the 18s ribosomal rna gene was amplified with a set o ...201222231266
diversity of haemaphysalis-associated piroplasms of ruminants in central-eastern europe, hungary.increasing numbers of genetic variants are being recognized among piroplasms, but the precise taxonomical status, the tick vector and the geographical range of several species or genotypes are still unknown. bovine piroplasmosis was reported to re-emerge in north-east hungary. because theileria-infection was newly diagnosed in one cattle herd in the same region of the country, the aim of this study was to molecularly identify the relevant agent, to find its local vector tick species, and to exam ...201526652614
a survey of ixodid tick species and molecular identification of tick-borne pathogens.this study was undertaken in two different climatic areas of turkey to determine the presence of tick-borne pathogens of medical and veterinary importance. the ticks were removed from humans, pooled according to species and developmental stages, and analyzed by pcr, reverse line blot (rlb) and sequencing. of the 2333 removed ticks from 10 species, 1238 (53.06%) were obtained from the arid cold zone, and the remaining 1095 (46.93%) were obtained from the humid zone. the removed ticks were identif ...201424424312
genetic variability of babesia parasites in haemaphysalis spp. and ixodes persulcatus ticks in the baikal region and far east of study babesia diversity in ixodid ticks in russia, ixodes persulcatus, haemaphysalis japonica, haemaphysalisconcinna, dermacentor silvarum, and dermacentor nuttalli ticks collected in the far east and baikal region were assayed for the presence of babesia spp. using nested pcr. in total, babesia dna was detected in 30 of the 1125 (2.7%) i. persulcatus, 17 of the 573 (3.0%) h. concinna, and 12 of the 543 (2.2%) h. japonica but was undetectable in any of the 294 analyzed dermacentor spp. partia ...201425460820
