The aim of performed study was to determine the level of enzootic abortion (EA) in sheep breeding farms in different districts of Lithuania, to determine differences in clinical signs and infection frequency between various age groups, and to evaluate the sensitivity and specificity of complement fixation test for antibodies detection and indirect immunofluorescence for antigen detection in sheep chlamydiosis. The clinical, serological and immunological tests in sheep farms were performed in 2004 and 2005. Comparing different age groups of sheep revealed that the lowest number of infected sheep was registered in animals younger than 18 months (23.1%, antibodies titre 3.191 log2, P<0.05) and highest in animals aged 18 to 24 months (53.8%, antibodies titre 4.224 log2, P<0.001). In sheep aged more than 3 years, titre of antibodies was significantly reduced. The majority of infected sheep which aborted (86.4%) was registered in 18-24 month age group. Furthermore, in sheep which aborted the infection level was 2.5-fold higher as compared to sheep which didn’t abort. Analysis of smears from patological material by indirect FAT revealed that 54.5% of animals were positive to Chlamydophila abortus infection. The highest prevalence of chlamydia (66.7%) was registered in placentas of sheep which aborted.

A serological study of BoHV-1 distribution was conducted in Lithuania from 2005 to 2009. Antibody level was measured using a commercial ELISA. For serological examination, 15,368 random blood samples from cattle of different age, gender, and size of herd, which was unvaccinated against IBR, were collected in 37 districts. It was registered that 11.97% of BoHV-1 were seropositive samples. It was also shown that BOHV-1 is most widespread in cattle herds with population >200 individuals (14.79%). Comparison of different sex groups of cattle revealed that the highest number of infected animals was identified in cows (34.64%) and the lowest in bulls (2.01%). In heifers the number of infected animals was 10.01% and in calves - 4.41%. It was shown that seroprevalence of BoHV-1 infection in Lithuania increased with age of animals. The highest prevalence of BoHV-1 (53.98%) was registered in cattle aged more than 7 years.
