Abstract_ Background The occurrence of Mannheimia species in healthy sheep has only been investigated to a very limited extend since the genus and its five named species were established.

Methods Typical -haemolytic Pasteurellaceae were isolated from nasal swabs and subsequently subjected to bacteriological examination. A total of 57 Mannheimia isolates were obtained
