b a ckground: babesiosis is a haemoparasitic disease of domestic and wild animals caused by species of the genus bab esia . bab esia bigemina , b . bovis and b . divergens are known to be pathogenic in cattle. the disease is transmit- ted during blood feeding by infected ticks and is the most economically important tick-borne disease in tropical and subtropical areas. ixodid ticks are vectors i...

Sets of four kudus were shot and examined for arthropod parasites at approximately monthly intervals from April 1981 to March 1983 in the southern part of the Kruger National Park, eastern Transvaal Lowveld. These animals harboured 10 ixodid tick species of which Boophilus decoloratus followed by Amblyomma hebraeum were the most abundant. The seasonal abundances of these ticks and of Amblyomma ...

background : boophilus annulatus is an obligate blood feeder tick that can cause great losses in animals due to anemia and its ability to injure its host skin directly. the aim of this study was identification of cattle humoral immune response to some tick proteins during experimental infestation. methods : immune sera against tick were collected from experimentally infested cattle with ticks. ...

this study was conducted during 3 years period (2002-2004). tick sampling was carried out randomly from domestic animals during seasonal activity of ticks from different parts of iran. 2170 ticks from 151 cattle, 629 sheep, 336 goats and 33 camels were collected. the occurance of tick infestation in cattle, sheep, goats and camels was 60%, 71.4%, 53% and 46 % respectively. sampled ticks of rhip...

Four new species of the genus Hemicriconemoides (H. californianus n.sp., H. taiwanensis n.sp., H. annulatus n. sp., and H. nitida n.sp.) are described. The range of total length of H. mangiferae is increased on the basis of specimens collected in Israel, Observations on H. mangiferae and H. litchi support the validity of H. litchi as distinct from H. mangiferae.

The epizootiology of the microsporidium Amblyospora albifasciati was studied in natural populations of its definitive host, a multivoltine, neotropical, floodwater mosquito, Aedes albifasciatus, and its intermediate copepod host, Mesocyclops annulatus, in an ephemeral floodwater habitat during a 12-month period. A. albifasciati was enzootic in mosquitoes. Vertically (transovarially) transmitted...
