Adult Amblyomma hebraeum ticks, the principle vector of heartwater (cowdriosis) of domestic ruminants in southern Africa, were collected in pheromone traps placed in Kruger National Park, an exclusively wildlife sanctuary in South Africa. These ticks transmitted Cowdria ruminantium, the rickettsi...

The relationship between prevalence of trypanosomal infections (Trypanosoma congolense) and average packed cell volume (PCV) in herds of communally managed adult Angoni breed cattle was investigated in four districts of eastern Zambia. In all areas, regression analyses showed that the herd averag...

Analysis of the transmission dynamics of Cowdria ruminantium, the tick-borne rickettsial agent of heartwater in ruminants, requires accurate measures of infection in vector populations. To obtain these, Amblyomma hebraeum ticks were collected at two heartwater-endemic locations in the lowveld and...

From November 2003 to October 2004, the prevalence rate of ovine fasciolosis in small-scale irrigation schemes found in three different agro-ecologic zones of the Upper Awash River Basin was assessed. An overall fasciolosis infection prevalence rate of 56.3% (729/1296) was recorded in examined sh...

Contagious bovine pleuropneumonia (CBPP) is a respiratory disease of cattle caused by Mycoplasma mycoides subsmycoides small colony. CBPP has been and is still a major cause for concern for African countries (due to mortality, animal-production losses and cost of monitoring and control). A cross ...

Aetiological investigation was made into an outbreak of skin disease (alopecia) in 216 Menz weaner lambs in Ethiopia, through clinical, laboratory and post mortem examinations. Morbidity, mortality and case fatality rates were 84.7%, 50.5% and 59.6%, respectively. The clinical signs included symm...

In this paper, available data on the distribution, economic importance and efforts made so far towards the control of Newcastle Disease (ND) in Ethiopia were presented. ND is the single major health constraint, which causes heavy mortality and morbidity to village chicken and affects productivity...

A serological survey was carried out in the central highlands of Ethiopia to investigate the significance of maedi-visna on sheep reared in two types of management, on-station and on-farm. A total of 349 serum samples were collected in January 1996 from ILRI Debre Berhan station (n=203) and adjac...

Presents a study carried out on farms and on-station at Debre Berhan from July 1989 to December 1990 to determine the causes of morbidity and mortality of lambs up to 6 months of age. It showed pneumonia (bacterial and/or verminous), starvation-mismothering exposure (SME) complex, gastrointestina...
