Clinical Cases of Contagious Bovine Pleuropneumonia (CBPP) among Calves in Vaccinated Cattle Herds in Zambia: A Case Study

An observational study was conducted to ascertain the clinical manifestation of Contagious Bovine Pleuropneumonia (CBPP) in the Western Province of Zambia following an outbreak in an endemic region. It was observed that both calves and adult cattle in 9 herds that were not vaccinated with CBPP T1/44 vaccine reported mortality while 24 herds that had consistently been vaccinated against CBPP only reported mortalities in calves between 2 months and 8 months of age. This observation indicates that in CBPP endemic areas, calves may acquire the disease from the carriers in the infected herds.
