Chlamydophila abortus in a brown skua (Catharacta antarctica lonnbergi) from a subantarctic island
On Bird Island, South Georgia, a new strain of Chlamydophila abortus was detected in one Brown skua out of 37 specimens from six different seabird species. Phylogenetic analysis of thernpB and omp1 genes indicated the strain to be more closely related to

Reinfection withChlamydophila abortusby Uterine and Indirect Cohort Routes Reduces Fertility in Cattle Preexposed toChlamydophila [PDF]
ABSTRACTThis study investigated the effects of controlled reinfection on fertility of cattle naturally preexposed toChlamydophila abortus. All animals had high prechallenge levels of immunoglobulin M (IgM), IgG, IgG1, and IgG2 serum antibodies against ruminantC. abortusin a chemiluminescent enzyme-linked immunosorbent assay.

Parachlamydia spp. and Related Chlamydia-like Organisms and Bovine Abortion
Chlamydophila abortus and Waddlia chondrophila cause abortion in ruminants. We investigated the role of Parachlamydia acanthamoebae in bovine abortion. Results of immunohistochemical analyses were positive in 30 (70%) of 43 placentas from which Chlamydia-

Experimental infection of pregnant ewes with enteric and abortion-source Chlamydophila abortus
Two groups of pregnant ewes were experimentally infected oronasally in midpregnancy. A faecal and an abortion-source isolate of Chlamydophila abortus were used. They were derived from a healthy ewe from a flock with no history of abortion, and from an aborted foetus in a farm with enzootic abortion. As assessed by modified Ziehl-Neelsen (MZN) staining,

Validation of a PCR Assay for Chlamydophila abortus rRNA gene detection in a murine model
Chlamydophila abortus (C. abortus) is associated with reproductive problems in cattle, sheep, and goats. Diagnosis of C. abortus using embryonated chicken eggs or immortalized cell lines has a very low sensitivity.
