* Chlamydia in catlle, a cause for concern?

During the year 1996 farmers and vets alike were puzzled by a change in disease pattern in cattle that couldn’t be readily explained. Although, at this time, it looked as only single animals in a herd were affected, with hindsight it turned out to be far more widespread than previously diagnosed. The symptoms of the condition I refer to as Chlamydiosis are varying, Chlamydia infection may lead to different diseases in a given host species which are difficult to distinguish from diseases with similar symptoms but caused by other infectious agents.

The genus Chlamydia comprises a unique class of bacteria that cause infection in men and animals. This intracellular pathogen develops within a vacuole inside the host cell, termed an inclusion. Like a virus, the organism replicates only within the host cell, hence Chlamydia are described as obligate intracellular parasites.

* Quantitative Detection of Chlamydia psittaci and C. pecorum by High-Sensitivity Real-Time PCR Reveals High Prevalence of Vaginal Infection in Cattle

Over the last 40 years, evidence has accumulated to suggest the ubiquitous presence of infections with intracellular bacteria of the genus Chlamydia in cattle and other livestock species. Despite some improvement in diagnostic techniques, our understanding about the prevalence and pathogenetic significance of these infections, succinctly reviewed by Shewen (11) in 1980, has not substantially changed since that time.
