Serological study of porcine reproductive and respiratory syndrome virus (PRRSV) infection in pigs and wild boars was conducted in Lithuania between 2009 and 2013. Antibody level was measured using a commercial ELISA. The 4.32% (95% CI 3.92-4.72) out of 9856 examined porcine sera were positive for the PRRSV antibodies. The antibodies were detected in 11.82% (95% CI 10.28-13.36) of all investigated serum samples of sows and gilts. As much as 8.2% of serologically positive samples (95% CI 6.83-9.57) were determined in the piglets under three months of age. Considerably smaller (P < 0.05) seroprevalence was detected in boars (0.62%) and fattening pigs (1.84%). From 1357 examined sera of wild boar, collected between 2009 and 2013 hunting seasons, 5.38% (95% CI 4.52-8.2) of samples were positive for PRRSV antibodies in 23 locations out of 50 investigated. The analysis of seroprevalence in different age groups of wild boars showed that PRRSV antibodies were detected in all age groups; however, it was significantly higher in adults than in juveniles or subadults and reached up to 10.02% (95% CI 7.39-12.65).

The aim of this study was to investigate the influence of long-term building construction noise from refurbishment, which including vibration, on some physiological parameters and histopathological changes of organs of Wistar rats. Twenty 12 month old female rats were divided into two groups: rats group I (n = 10) were exposed to long-term construction noise and rats group II (n = 10) were kept under normal noise level. Study results revealed that long-term construction noise from building refurbishment has an influence on body weight, haematological and some serum biochemical parameters affects caecal microbiota, and causes histopathological changes in the organs of adult female Wistar rats. It was noticed that rats in group I exihibited significantly higher mean values for total protein, albumin and lower values for glucose, AST, ALT, blood urea nitrogen, haematological and caecal microbiota parameters than rats in group II. The most common pathologies were determined in the kidney, liver and lungs. Other observed pathologies were lymphadenopathy, catarrhal inflammation of the intestines, spleen hyperplasia and mammary gland adenofibroma. Single cases were subcutaneous fibroma in the thoracic region, abortus with uterine inflammation and thymus hyperplasia with formation of cysts were found.
