Occasionally the occurrence of isolates of the genus Bordetella has be
en reported, with unclear assignment to one of the known species in sh
eep from New Zealand and Great Britain. In this study we describe the
isolation of strains belonging to the genus Bordetella in a flock of s
heep from Germany. These isolates were characterized biochemically by
serological tests and whole cell fatty acid analysis. Our isolates cou
ld be divided into three subgroups by their differential growth on Mac
Concey- and Tyrosine agar. A clear assignment to one of the known Bord
etella species was not possible.
