The objective of this work was to determine nucleoprotein gene sequences and genetically characterise the rabies virus (RABV) isolates in order to know which virus group (biotype) is circulating in the raccoon dog population in Lithuania. For rabies virus phylogenetic characterisation, 16 RABV isolates from raccoon dogs were used. The isolates were selected according to different geographical location. A 400 bp region of the nucleoprotein gene was sequenced and analysed together with reference raccoon dog sequences of the RABV isolates from Estonia, Latvia, Russia, Poland, and other West European countries available in the GenBank. Phylogenetic analysis revealed that the isolates from different parts of Lithuania were closely related and belonged to RABV genotype 1 and showed significant bootstrap support inside North-Eastern Europe group of raccoon dog RABV. The phylogenetic relationships between Lithuanian raccoon dogs RABV isolates and those from neighbouring countries showed 97.7%- 99.5% identity. A close genetic relationship between the raccoon dog and fox rabies isolates from different regions of Lithuania (99.5%) was identified, suggesting that rabies viruses circulating in raccoon dogs and foxes in this region might have the same origin.

The aim of the present study was to detect canine parvovirus (CPV) from faecal samples of clinically ill domestic dogs by polymerase chain reaction (PCR) followed by VP2 gene partial sequencing and molecular characterization of circulating strains in Lithuania. Eleven clinically and antigen-tested positive dog faecal samples, collected during the period of 2014-2015, were investigated by using PCR. The phylogenetic investigations indicated that the Lithuanian CPV VP2 partial sequences (3025-3706 cds) were closely related and showed 99.0-99.9% identity. All Lithuanian sequences were associated with one phylogroup, but grouped in different clusters. Ten of investigated Lithuanian CPV VP2 sequences were closely associated with CPV 2a antigenic variant (99.4% nt identity). Five CPV VP2 sequences from Lithuania were related to CPV-2a, but were rather divergent (6.8 nt differences). Only one CPV VP2 sequence from Lithuania was associated (99.3% nt identity) with CPV-2b VP2 sequences from France, Italy, USA and Korea. The four of eleven investigated Lithuanian dogs with CPV infection symptoms were vaccinated with CPV-2 vaccine, but their VP2 sequences were phylogenetically distantly associated with CPV vaccine strains VP2 sequences (11.5-15.8 nt differences). Ten Lithuanian CPV VP2 sequences had monophyletic relations among the close geographically associated samples, but five of them were rather divergent (1.0% less sequence similarity). The one Lithuanian CPV VP2 sequence was closely related with CPV-2b antigenic variant. All the Lithuanian CPV VP2 partial sequences were conservative and phylogenetically low associated with most commonly used CPV vaccine strains.

The objective of this study was to evaluate the diversity and persistence of porcine reproductive and respiratory syndrome virus (PRRSV) in a swine herd where American type of modified live vaccine (MLV) was used. The study was carried out on the farrow-to-finish farm with 2 500 sows, which had a history of endemic PRRSV manifested as periodic mini-outbreaks of PRRS. The farm has been endemically infected with PRRSV-EU since 1998. The vaccination programme with the MLV was first applied in 2001 and consisted of vaccinating all sows every six months and all gilts 60 d before farrowing. All incoming gilts were also vaccinated twice with a two-week interval. During the monitoring period, PRRSV-EU type was detected in 28 of 63 samples collected from two to three-month-old piglets. PRRSV-US type was detected in 20 samples. Nineteen samples were positive for both EU and US types of PRRSV at the same time. The results of RT-PCR testing serum samples from 58 sows were negative. ORF5 RT-PCR products from samples containing both PRRSV-EU and PRRSV-US types were sequenced. Phylogenetic analyses, showed a close relationship to the American genotype of PRRSV strains from the monitored farm to the known vaccine strain V2332 present in the American type PRRS MLV. The presence of the PRRSV-US in the two-three-month-old piglets indicates that the American type of vaccine virus has spread from vaccinated sows to the non-vaccinated piglets. Simultaneous presence of both PRRSV-EU and US strains in 19 samples suggests very low cross protection between the American type PRRS MLV and very diverse Lithuanian EU type field strains. In this situation an increased chance for inter-genotypic recombination can be a threat.

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).
