Chlamydial abortion
The enzootic abortion is a by Chlamydia abortus (= Chlamydophila abortus induced) infectious disease in sheep and goats , with Verlammen associated. It belongs to the chlamydiosis and is a reportable animal disease in these animal species in Germany . In addition, cattle and, albeit to a lesser extent, humans are susceptible, which is why chlamydial abortion should be regarded as a zoonosis .
Pathogen
The pathogen, Chlamydophila abortus (formerly: Chlamydia psittaci ) is an immobile, gram-negative bacterium that lives within cells . It has a two-phase intracellular development cycle. The pathogen has little resistance ( tenacity ) to external chemical and physical influences .
The infection occurs orally through food, water and bedding. Droplet infection is also possible with intensive animal contact .
Clinical picture
The incubation period is about 8 weeks. Typical of the disease are miscarriages in the second half of pregnancy , with an emphasis shortly before lambing, as well as the birth of dead or weak lambs. Often one is retained placenta and uterine infection found. Colick- like pain and vaginal discharge may appear shortly before the sore .
The diagnosis is made by antibodies - or the pathogen detection from abortion material. In terms of differential diagnosis , Campylobacter abortion , toxoplasmosis , Q fever , salmonellosis , brucellosis and neosporosis must be considered.
therapy
The treatment is carried out with antibiotics ( macrolide antibioca ). The prospect of recovery and the prognosis for future pregnancies are good.
