The polymerase chain reaction and oligonucleotide probing were used to detect Theileria and Cowdria species in DNA extracted from blood and ticks recovered from 24 African buffalo during a gamecapture operation in the Kruger National Park, South Africa. Species-specific probing indicated that all but one of the buffalo were carrying at least one Theileria species. Indirect fluorescent antibody ...

Received: Revised: Accepted: Published online: June 18, 2016 October 13, 2016 October 14, 2016 November 17, 2016 The word-wildly spread Theileria, is an economical important parasite to sheep and goats production. However, a little is known about whether goats in Hubei province are exposed to Theileriosis. Therefore, a survey was conducted to investigate the prevalence of Theileria infection in...

Theileria parasites infect and transform cells of the ruminant immune system. Continuous proliferation and survival of Theileria-transformed cells involves the well-orchestrated activation of several host-cell signalling pathways. Constitutive NF-kappa B (nuclear factor kappa B) activation is accomplished by recruiting the IKK (I kappa B kinase) complex, a central regulator of NF-kappa B pathwa...

This study was carried out in order to detect antibodies to Babesia (Theileria) equi in the local breed of horses in the province of Kars, Turkey. A total of 108 serum samples from apparently healthy horses in eight villages were examined for B. equi antibodies by an indirect immunofluorescent antibody test (IFAT). Of the 108 samples tested, 27 (25%) were found to be seropositive. The horses sa...

The prevalence of Theileria lestoquardi antibodies in Sudanese sheep from nine geographical areas in Sudan was determined using indirect fluorescent antibody "IFA" test. Out of 315 samples examined, 51 (16.2%) were found positive and ranged between 23.4% in River Nile State and 10% in Kasala and Darfour Provinces with an overall prevalence of 16.2% indicating widespread distribution of the infe...

Four hand-reared, naïve roan antelope, 4 months of age, were exposed to naturally infected pasture on a game farm in Mpumalanga Province, South Africa, where roan are known to die from theileriosis. Various clinical parameters were recorded during this period. The predominant ticks parasitising these animals at the time (January to February), were Rhipicephalus appendiculatus and Rhipiceph...

The development of sensitive surveillance technologies using PCR-based detection of microbial DNA, such as the reverse line blot assay, can facilitate the gathering of epidemiological information on tick-borne diseases, which continue to hamper the productivity of livestock in many parts of Africa and elsewhere. We have employed a reverse line blot assay to detect the prevalence of tick-borne p...

In this preliminary study, a novel DNA microarray system was tested for the diagnosis of bovine piroplasmosis and anaplasmosis in comparison with microscopy and PCR assay results. In the Dakahlia Governorate, Egypt, 164 cattle were investigated for the presence of piroplasms and Anaplasma species. All investigated cattle were clinically examined. Blood samples were screened for the presence of ...

We report the detection of Theileria annulata, the causative agent of tropical theileriosis, by PCR in blood samples obtained from carrier cattle. The assay employs primers specific for the gene encoding the 30-kDa major merozoite surface antigen of T. annulata. A 721-bp fragment was amplified from blood samples taken monthly from calves experimentally infected with one of four different stocks...

Little is known about tick-borne diseases in Saudi Arabia, particularly regarding the prevalence of theileriosis in small ruminants. This survey studied the potential vectors of malignant theileriosis in Saudi Arabian sheep. Blood, lymph node and tick samples were collected from animals being treated or necropsied at the Veterinary Diagnostic Laboratory in Jeddah, Makkah (western region), and B...
