Clinical Borrelia theileri infection was reported for the first time in cattle from Botswana concurrent with Babesia bovis and Theileria mutans infections. Two animals, an ox and a cow of the Tswana breed demonstrated clinical signs of fever, haemoglobinuria, inappetance, diarrhoea, pallor of mucous membranes, enlarged superficial lymph nodes and rough hair coats. Examination of the blood smears from the affected animals revealed numerous B. theileri, and very few B. bovis and T. mutans organisms. Oxytetracycline was administered parenterally to all the animals in the herd. The ox, being extremely weak and recumbent for the previous 4-5 days, succumbed to death the day after the examination. The clearance of spirochaetes from the blood circulation and recovery of the cow three days after treatment with oxytetracycline suggest an involvement of B. theileri in producing clinical disease. 相似文献

A cross-sectional serological survey of the prevalence of brucellosis in ruminants in the Region of Republican Subordination and Khatlon oblasts (provinces) in Tajikistan was conducted in May 2003. Sera from 13,625 ruminants involving 3513 households in 172 kishlaks (villages) were collected and screened by the rose bengal test. Doubtful and positive results were further tested with competitive and indirect elisas. The overall serological prevalences (95 per cent confidence intervals [cis]) were 5.8 per cent (5.2 to 6.4 per cent) for sheep, 5.5 per cent (5.0 to 6.0 per cent) for goats and 2.1 per cent (1.0 to 3.2 per cent) for cattle. The results show that brucellosis was a common disease of ruminants that was widely but unevenly distributed throughout the two oblasts. Seropositive animals were found in 119 of the 172 kishlaks (69.2 per cent [95 per cent ci 61.9 to 75.6 per cent]) and 14.4 per cent (95 per cent ci 13.3 to 15.6 per cent) of the 3513 households. Evidence of infection was also found in cattle kept for milk production in urban kishlaks in two major cities and in state-owned dairy farms. 相似文献

Bovine farcy is described for the first time in Ghana in herds kept in the Aveyime area of the Accra Plains. Reasons why the disease seems confined to a small geographical area are not yet clear. Different breeds of cattle are equally affected. Mineral deficiencies were not observed in the samples taken for analysis (Ca, Mg, P, Na, K, Cl). Limited examination of tick population on cattle showed a predominance of A. variegatum. Factors enhancing the pathogenicity and persistence of the Mycobacterium are still not clear. A study is soon to start. 相似文献

No sleeping sickness or nagana cases have been reported in Botswana since 1985. In view of several confirmed clinical cases of nagana and reports of heavy bovine mortality, a parasitological survey was conducted to determine the prevalence of trypanosome infection in cattle in Maun and Shakawe areas of Ngamiland district. Wet blood films, buffy coat and Giemsa-stained thick and thin blood smears were used to detect trypanosomes in animals. Overall,trypanosome infection rate was 15.98%, with 5.94% and 27.29% in Maun and Shakawe respectively. The urgent need to combat trypanosomosis in Ngamiland, particularly in the Shakawe area, is highlighted, and a 3-phase integrated tsetse control strategy for this disease problem is discussed. 相似文献

Ischaemia and terminal tissue dry gangrene are among the sequels of Salmonella infection. Up to now, these lesions had been described in Europe and in Chile, on calf exclusively. This time, the syndrome was observed on adult cattle reared in the Accra Plains (Ghana) and infected by S. typhimurium. This case give evidence of the spreading of salmonellosis on the African continent and should foster the search of adequate control measures. 相似文献
