The veterinary chlamydiae comprise all currently known organisms of the family Chlamydiaceae, except Chlamydia trachomatis. C. abortus is an economically important infection in sheep and goats causing abortion, stillbirths and weak neonates. Moreover, it is a zoonotic pathogen, i.e. well known for being transmissible from animals to humans and posing a risk for pregnant women. C. psittaci, which causes avian chlamydiosis in birds, is the most important veterinary chlamydial agent in terms of economic impact and human health. Avian chlamydiosis has been recently extended by addition of the novel species C. avium, C. gallinacea and Candidatus C. ibidis. In addition, C. felis, causing conjunctivitis in cats, and C. caviae, a guinea pig pathogen, can both be zoonotic. The latter has been extensively used in experimental animal models. Similarly, C. muridarum infection models in mice have been in use for decades to investigate human genital chlamydial disease. C. pecorum has a broad host range, including livestock and wild ruminants, but also marsupials such as the koala in Australia. C. pneumoniae, originally thought to occur only in humans, has a broad host range, including horses, koalas, reptiles and amphibians. C. suis, a pathogen of pigs, is the only chlamydial species to date that can maintain stable tetracycline resistance read more ...
