Abstract The risk of pathogen transmission continues to increase significantly in the presence tick vectors due trade livestock across countries. In Ghana, there is a lack data on incidence tick-borne pathogens that are zoonotic and veterinary importance. This study, therefore, aimed determine prevalence such using molecular approaches. A total 276 dry blood spots were collected from cattle (10...
A quantitative real-time PCR (qPCR) assay based on the cox III gene was evaluated for the simultaneous detection and discrimination of Theileria species in buffalo and cattle blood samples from South Africa and Mozambique using melting curve analysis. The results obtained were compared to those of the reverse line blot (RLB) hybridization assay for the simultaneous detection and differentiation...
Theileria spp. are tick-transmitted, intracellular apicomplexan protozoan parasites infecting a wide range of animals. As there is very limited information on the prevalence of Theileria spp. in the Caribbean we used the recently described genus-specific pan-Theileria FRET-qPCR to identify infected animals in the region and a standard 18S rRNA gene PCR and sequencing to determine the species in...
Tick-borne diseases (TBDs) caused by pathogens belonging to the genera Anaplasma, Ehrlichia, Babesia and Theileria in small ruminants are widespread tropical sub-tropical countries. The epidemiology of tick-borne (TBPs) is less understood compared those infecting cattle general. This study was carried out investigate characterize TBPs sheep goats using molecular tools. A total 107 blood samples...
The genus Theileria includes tick-transmitted apicomplexan parasites of ruminants with substantial economic impact in endemic countries. Some species, including Theileria parva and Theileria annulata, infect leukocytes where they induce phenotypes that are shared with some cancers, most notably immortalization, hyperproliferation, and dissemination. Despite considerable research into the affect...
BURRIDGE, M. J., BROWN, C. G. D., AND KIMBER, C. D. 1974. Theileria anndata: Cross-reactions between a Cell Culture Schizont Antigen and Antigens of .East African Species in the Indirect Fluorescent Antibody Test. Experimental Parasitology 35, 374380. A schizont antigen for the indirect fluorescent antibody test was prepared from an in &TO culture suspension of lymphoid cells infected with Thei...
Blood samples were collected from 71 tsessebes relocated from the deproclaimed Vaalbos National Park to Mokala National Park, South Africa. DNA was extracted from the samples and the reverse line blot (RLB) hybridization technique was used to detect and identify any haemoparasites present. Six samples hybridized to the Theileria/Babesia genus-specific probe, the Theileria genus-specific probe a...
This study aimed to evaluate protection induced by the vaccine candidate B. ovis ΔabcBA against experimental challenge with wild type B. ovis in rams. Rams were subcutaneously immunized with B. ovis ΔabcBA encapsulated with sterile alginate or with the non encapsulated vaccine strain. Serum, urine, and semen samples were collected during two months after immunization. The rams were then challen...
