Research data from D.A. Salih and colleagues update understanding of borne disease
2007 NOV 21 -- According to a study from Borstel, Germany, "A herd-based study was carried out in Central Equatoria State, Southern Sudan, to study epidemiological aspects of tick-borne diseases. Six herds of cattle situated in three different locations were selected and investigated every 3 months during the year 2005." "Blood smears for Giemsa staining and blood spots on filter paper for deoxyribonucleic acid extraction were collected from 600 apparently healthy indigenous cattle. A total of 69 (11.5%) samples showed the presence of piroplasms in Giemsastained blood smears, and polymerase chain reaction increased the detection limit to 297 (49.5%). Using reverse line blot, it was possible to detect and differentiate eight different piroplasms namely, Theileria parva (71.2%), Theileria mutans (73%), Theileria velifera (45.3%), Theileria taurotragi (2.7%), Theileria buffeli (0.5%), Theileria annulata (0.2%), Babesia bovis (1.7%), and Babesia bigemina (0.3%). Mixed infections were detected in 406 samples (67.7%) accounting for 17 different combinations. High infection of Theileria parva was reported among young calves compared to older cattle. The highest prevalence of Theileria parva was reported in the rainy season (October)," wrote D.A. Salih and colleagues. The researchers concluded: "The implications of these results on the epidemiology of tick-borne diseases are discussed with emphasis on East Coast fever." Salih and colleagues published their study in Parasitology Research (Epidemiological studies on tick-borne diseases of cattle in Central Equatoria State, Southern Sudan. Parasitology Research, 2007;101(4):1035-1044). For more information, contact J.S. Ahmed, Research Center Borstel, Division Vet. Infection Biology & Immunology, Parkallee 22, D-23845 Borstel, Germany.
