Intranasal Infection with Chlamydia abortus Induces Dose-Dependent Latency and Abortion in Sheep

Intranasal Infection with Chlamydia abortus Induces Dose-Dependent Latency and Abortion in Sheep

BACKGROUND Latency is a key feature of the animal pathogen Chlamydia abortus, where infection remains inapparent in the non-pregnant animal and only becomes evident during a subsequent pregnancy. Often the first sign that an animal is infected is abortion occurring late in gestation. Despite this, little is understood of the underlying mechanisms that control latency or the recrudescence of inf...

Seroprevalence of Chlamydia abortus infection in sheep and goats in Iran

BACKGROUND: Chlamydia abortus is a zoonotic bacteriumthat commonly causes abortions in ruminants. This microorganismis one of the most important infectious agents causingabortion and major economic losses in sheep and goats worldwide.OBJECTIVES: The objective of this study was investigatingthe status of C. abortus infection among small ruminantflocks of some regions in Iran. METHODS: A total of...

Abortion due to Brucella abortus in Sheep in Iran

Pathogenic outcome following experimental infection of sheep with Chlamydia abortus variant strains LLG and POS

This study investigated the pathogenesis of two variant strains (LLG and POS) of Chlamydia abortus, in comparison to a typical wild-type strain (S26/3) which is known to be responsible for late term abortion in small ruminants. Challenge with the three strains at mid-gestation resulted in similar pregnancy outcomes, with abortion occurring in approximately 50-60% of ewes with the mean gestation...
