Sažetak
In addition to zoonotic potential, Chlamydia (C.) abortus is a very important bacterium causing serious disease in small ruminants. The main outcome of the disease is abortion in the late stages of pregnancy and the economic impact for farms is significant. During a three-year period (2015–2017), 191 vaginal swabs, 24 placentas, 210 foetal organs and 2 milk samples from small ruminant abortion cases were tested for C. abortus by real-time PCR. Positive samples were detected on eight sheep farms and two goat farms, with 8.4% of total samples testing positive samples. These samples were characterised using the
MLVA method, and a single MLVA genotype (genotype [2]) was identified from sheep and goat samples, suggesting highly conserved C. abortus strains among the national flock. This study is the first description of C. abortus as a causative agent of abortion in goats in Croatia. More detailed study is required to recognize the epidemiological relevance of the abortion chlamydiosis. An open register of farms with defined health status should be established for each farm at the national level for better disease(s) control.
