Summary

An outbreak of haemorrhagic septicaemia caused byPasteurella multocida in beef cattle in Zimbabwe grazing effluent-irrigated pastures, is described. The outbreak occurred during the wet summer months and predisposing stress factors included excessive rainfall and unusual cold weather during the preceeding month. History, clinical features and post-mortem findings were consistent with reports of the disease from other countries, except that meningitis was also a constant feature. Morbidity approached 77% and mortality 5 per cent. Prophylactic treatment and vaccination with a killed bacterin together with a return of warmer and drier weather were probably important in halting the outbreak.

Résumé

Les auteurs décrivent un début de septicémie hémorragique àPasteurella multocida dans un troupeau de boeufs, au Zimbabwé, pâturant sur des prairies irriguées par des affluents. Le foyer s'est déclaré pendant les mois humides de l'été. Parmi les facteurs prédisposants et stressants, on a noté des chutes de pluies excessivement abondantes et un temps froid inhabituel durant le mois précédent. L'anamnèse, les aspects cliniques et les résultats des autopsies se sont révélés cohérents avec la relation de la maladie dans d'autres pays, à l'exception de la méningite qui s'est constamment manifestée. La morbidité a approché 77 p. 100 et la mortalité 5 p. 100. Un traitement prophylactique et une vaccination avec des bactéries tuées en même temps que le retour d'un temps plus chaud et plus sec ont probablement contribué à enrayer le foyer.

Resumen

Se describe un brote de septicemia hemorrágica en ganado bovino, causada porPasteurella multocida, en Zimbabwe El brote ocurrió durante los meses lluvisos de verano, los que se caracterizaron por precipitación pluvial excesiva y frío. La historia, síntomas clínicos y hallazgos posmortem, concuerdan con los descritos en otros países, excepto por la menigitis encontrada. La morbilidad fue de aproximadamente 77% y la mortalidad cinco por ciento. El tratamiento profiláctico instituído, la vacunación con bacterina y el retorno a la normalidad climática, fueron factores probablemente importantes para detener el brote.
