Bovine borreliosis in Botswana
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.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

The resurgence of trypanosomosis in Botswana : short communication
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
