Longitudinal-Survival Models for Case-Based Tuberculosis Progression.

Tuberculosis (TB) disease continues to be responsible for a high global burden with an estimated 10 million people falling ill each year and an estimated 1.45 million deaths. Widely carried out analyses to utilize routine data coming from this disease, and well-established in literature, have paid attention to time-to-event with sputum smear results being considered only at baseline or even ignored.

Methane and Nitrous Oxide Emissions from Cattle Excreta on an East African Grassland.

Greenhouse gas (GHG) emission measurements from livestock excreta in Africa are limited. We measured CH and NO emissions from excreta of six Boran () and six Friesian () steers near Nairobi, Kenya. The steers were fed one of three diets (T1 [chaffed wheat straw], T2 [T1 + Meissner - 0.

Taenia saginata cysticercosis: a comparison of routine meat inspection and carcase dissection results in calves.

Seventy-nine calves aged between two and 12 months, originating from a known Taenia saginata endemic area, were slaughtered and the carcases subjected to routine meat inspection and afterwards dissected and sliced. At dissection 75.9 per cent were found infected.

The efficacy of praziquantel against Taenia saginata cysticercosis in naturally infected calves.

The effect of Praziquantel on Taenia saginata cysticerci was investigated in a trial involving 80 calves from an endemic area in East Africa. When administered subcutaneously at a dose rate of 100 mg per kg of body weight Praziquantel killed all cysterci in all treated calves. A few cysticerci remained viable after a single subcutaneous infection at 50 mg/kg.
