| molecular epidemiological survey of theileria orientalis in thua thien hue province, vietnam. | theileria orientalis is a benign bovine protozoan parasite that occasionally causes serious economic loss in the livestock industry. we report the findings of a molecular epidemiological survey of t. orientalis in 94 vietnamese yellow cattle, 43 water buffaloes, 21 sheep, 21 goats and 85 blood-sucking ticks of cattle in the thua thien hue province of vietnam. the major piroplasm surface protein (mpsp) gene of t. orientalis was detected using polymerase chain reaction from 13 cattle (13.8%), 11 w ... | 2010 | 21187678 |
| phylogenetic analysis of theileria species transmitted by haemaphysalis qinghaiensis. | the phylogenetic relationships between six isolates of theileria spp. infective to small ruminants, and two isolates of theileria spp. infective to yak, all transmitted by haemaphysalis qinghaiensis, together with the theileria orientalis/sergenti/buffeli group and t. sinensis, were analyzed using the 18s ssrrna gene sequence. the target dna segment was amplified by polymerase chain reaction (pcr). the pcr product was used either for direct sequencing or was ligated to the pcr ii vector for sequ ... | 2004 | 14598167 |
| cattle and small ruminant piroplasmosis in macedonia, greece. | macedonia is an endemic region of cattle as well as of sheep and goat piroplasmosis in cattle, theileria orientalis (=t. buffeli?), the agent of eurasian benign theileriosis, is the most common and widespread piroplasm species. t. annulata, the agent of tropical theileriosis, seems to be rare and limited to few foci, but causes very severe clinical cases, especially in imported pure-bred or cross-bred animals. babesia bovis and b. bigemina are present in several localities, and often coexist. ca ... | 1999 | 11071550 |
| theileria orientalis, a cosmopolitan blood parasite of cattle: demonstration of the schizont stage. | serological and morphological comparison of theileria orientalis stocks from australia, britain, iran, japan and the usa with a more pathogenic stock from korea, corresponding to t sergenti of russian literature, showed that they all belong to one species, for which the name t orientalis is recommended. t orientalis is now known to occur on all continents. macroschizonts and microschizonts, found in some of the calves infected with the korean stock, are described and illustrated. infections with ... | 1985 | 3925510 |
| piroplasms of domestic animals in the macedonia region of greece. 1. serological cross-reactions. | during a serological survey on haemoparasites in macedonia, serum samples were collected from cattle, sheep and goats. all sera were tested by the indirect immunofluorescence test (ifat); the cattle sera against theileria orientalis, t. annulata, babesia bigemina, b. bovis, b. divergens and b. major antigens; the sheep and goat sera against t. ovis, b. ovis, b. motasi and b. crassa antigens. parallel tests of negative and positive control sera against all the antigens showed the existence of cro ... | 1996 | 8792579 |
