Prevalence of porcine circovirus 2 infection in pig population in Slovakia

This study describe the seroprevalence of porcine circovirus type 2 (PCV2) in north eastern hill (NEH) states of India. Information on PCV2 from NEH states is lacking. Serum samples (306) were collected from the pigs and different epidemiological parameters like age, sex, and litter size of drift or sounder, system of rearing and different clinical symptoms from November 2017 to May 2018. Samples were screened for PCV2 infection by commercially available ELISA kit (INGEZIM PCV IgG and INGEZIM PCV IgM, Ingenasa, Madrid, Spain). Out of 306 serum samples tested, 151 samples were positive for PCV2 infection. An overall PCV2 prevalence of 49.35% was recorded in NEH states of India. Highest prevalence was found in Sikkim (94%) and lowest prevalence in Nagaland (4%). This study revealed that PCV2 is prevalent in all the north eastern states of India which necessitates the need for implementation of prevention and control measures.

“…In our study, specific PCV2 antibodies were found in 74.8% of tested animals, and this result is very similar to the results from some other European countries, such as Spain, with seroprevalence of 72.7% (Rodriguez-Arrioja et al, 2003) and France with 80.2% (Blanchard et al, 2003). Seroprevalence determined in our study is lower compared to the results from Belgium with seroprevalence of 100% (Lefebvre et al, 2008), and higher than the results from Austria with seroprevalence of 60.0% (Schmoll et al, 2008) and Slovakia with 54.0% of animals tested positive (Csank et al, 2011). Seroprevalence determined in this study, however, is lower than in Canada with 82.4% (Liu et al, 2002) and the USA with 80.0% of specimens tested positive (Nawagitgul et al, 2002).…”

The aim of this research was to determine seroprevalence of infection caused by PCV2 in different categories of pigs on the territory of Vojvodina. The research was conducted on 6 pig farms placed in different locations on the territory of Vojvodina (two farms from the territory of Bačka, Banat and Srem, respectively), with the capacity from 500 to 2,500 sows with intensive management, closed type. Blood samples from brachiocephalic plexus were collected from 540 pigs in three different categories, in suckling piglets between 3 and 4 weeks of age, in weaned piglets from 8 to 9 weeks of age, and in fattening pigs between 20 and 22 weeks of age. Specific anti-PCV2 antibodies are determined by using indirect ELISA. Based on our results, we conclude that PCV2 infections are widely spread on the territory of Vojvodina, with total seroprevalence of 74.8%. The highest value of seroprevalence is determined in category of fattening pigs 86%, in suckling piglets this was 74.5%, while in weaned piglets seroprevalence was 65.3%.

AbstractPorcine circovirus type 2 (PCV2) associated diseases are a group of emerging devastating pig diseases worldwide. Due to a dearth of information on the virus in Nigeria, this study was carried out on 12 farms in Abeokuta Ogun State, Nigeria. Key production problems were identified through a questionnaire survey and direct field observations. The prevalence of the PCV2 was determined by the Polymerase Chain Reaction (PCR); 207 sera of pigs were obtained from the farms, DNAs extracted and amplified by the PCR. Based on gel results, the prevalence of PCV2 types were recorded and the effects of age, sex and geographic area determined. The observed production problems (and the percentage of farms suffering from such problems) were: runting (91.7 %), high piglet mortality (83.3 %), late term abortion (50 %), stillbirth (50 %) and anoestrous (41.7 %). The overall prevalence of 8.7 % of the PCV2 viral DNA was obtained. A single infection of PCV2b and PCV2a accounted for a prevalence of 5.3 % and 2.4 %, respectively, while a concurrent infection of both was found in only 1 % of the pigs. The prevalence of PCV2 was not significantly (P > 0.05) influenced by age or sex; with the rates in adults, growers and piglets being 9.9 %, 8.1 % and 8.1 %, respectively, while in males and females, the rates were 9.4 % and 9.0 %, respectively. The prevalence of PCV2 in high-density areas (13.2 %) was significantly (P < 0.05) higher than in low-density areas (4.0 %). It was concluded that PCV2a and PCV2b were present in pigs in Abeokuta, Nigeria and PCV2b was more prevalent. It was recommended that large-scale epidemiological studies covering all geographical regions be carried out with sequencing and phylogenetic analysis to characterize the PCV2 genotypes present in Nigeria.
