Chlamydophila abortus is one of the most important causative agents of enzootic abortion and other chlamydial infections of sheep and goats. The presence of specifi c serum antibodies to Chlamydophila abortus was studied in sheep and goats breeding in the Slovak Republic by the complement fi xation test. 22,040 sheep and goats were examined during 5 years. Specifi c anti-Ch. abortus antibodies were found in 2,360 out of 20,878 sheep sera examined (11.7%), and in 85 out of 1,162 examined goats (7.7%). The occurrence of antichlamydial antibodies indicates the importance of performing screening examinations in commercial breeding with the aim of reducing the spread of this disease between animals, and also interrupting the spread and transmission from animals to human.
The presence of antibodies against Chlamydophila (Chlamydia) psittaci in small mammals (Insectivora, Rodentia) in the region of East Slovakia are presented. The hosts were caught in several areas of Slovakia in habitats with different levels of anthropogenic disturbance. Research was carried out during 2000-2002. The authors examined 1,947 sera coming from 4 insectivore and 10 rodent species. Each serum was examined by micromethod of complement binding reactions using antigen Chlamydophila (Chlamydia) psittaci. Chlamydial infections were found in 251 individuals (prevalence 12.9%) of 8 mammal species. The antichlamydial antibodies were proved at levels ranging from 1:32-1:1024. The highest prevalence of antibodies was detected in the most abundant rodent species Apodemus microps (14.8%), Apodemus agrarius (13.9%), Apodemus flavicolis (12.4%), Microtus arvalis (12%), and Clethrionomys glareolus (10.9%). Positive hosts were registered in all studied localities. Testing of prevalence values in the individual research years confirmed significant changes. Our results showed that small mammals probably play an important role in the circulation of chlamydiae in nature.
