Chlamydophila pecorum: Typing
Jones et al., (1997) have described
subtypes of C. pecorum
have been described which vary in their ability to cause disease. Rodolakis et al.,
(1989) reported that C. pecorum isolated from the faeces of sheep were antigenically heterogeneous.
Variations in the major outer membrane protein (MOMP) of C. pecorum strains
from various conditions have been
observed by immunoblotting
(Fukushi and Hirai, 1992). However C. pecorum strains from several different
immunotypes have been shown to possess identical MOMP sequences (Kaltenboeck et al.,
1993). A key challenge is to identify for C. pecorum strains the relationships between immunotype, MOMP sequence, biological variation,
host tropism and
disease (Anderson et al., 1996).
