| a retrospective study of the prevalence and seasonal variation of fasciola gigantica in cattle slaughtered in the major abattoirs of zimbabwe between 1990 and 1999. | a retrospective study covering a period of 10 years (1990--1999) was conducted using post mortem meat inspection records of the veterinary department information management unit at harare to determine the prevalence and seasonal variation of bovine fasciolosis in zimbabwe. records of monthly and annual returns from five major abattoirs were examined in regard to total cattle slaughtered and the corresponding number of livers condemned due to fasciola gigantica infection. prevalence of fasciolosi ... | 2004 | 15580766 |
| History and critical review of Theileria parva (Boleni), the vaccine stock against Zimbabwean cattle theileriosis. | The paper reviews the infectivity, cross-immunization experiments, and cattle vaccination of Zimbabwean cattle-derived Theileria parva (Boleni) sporozoite stabilates produced at the Central Veterinary Laboratory (CVL) in Harare between 1980 and 2003. The Boleni stock was first isolated in July 1978 during a theileriosis outbreak and was shown to be virulent in susceptible cattle. Thereafter, the reactions observed in susceptible cattle produced by different tick stabilates derived from the origi ... | 2011 | 21890071 |
