Porcine circovirus type 2 viremia and seroconversion in pigs from a farm affected by postweaning multisystemic wasting syndrome.
نویسندگان
چکیده
The aim of the study was to assess the usefulness of real-time PCR and serological methods as indicators of postweaning multisystemic wasting syndrome (PMWS) occurrence. Significantly higher level of porcine circovirus type 2 (PCV2) viral load in serum and significantly lower titre of specific antibodies in PMWS-affected pigs indicated that combination of quantitative PCR and serological methods may support diagnosis of PMWS.

Detection of porcine circovirus types 1 and 2 in serum and tissue samples of pigs with and without postweaning multisystemic wasting syndrome.
Presence of porcine circovirus type 1 (PCV1) and PCV2 was studied in sera and superficial inguinal lymph nodes from postweaning multisystemic wasting syndrome (PMWS)-affected and non-PMWS-affected pigs by using in situ hybridization and PCR. PCV1 and PCV2 were found in less than 3% and more than 50% of the samples, respectively. The most sensitive technique and site was PCR in superficial ingui...

Materials and methods: In 2007, a PCV2 vaccine recommended for use in piglets ≥ 4 weeks of age was made available in New Zealand for control of porcine circovirus associated disease (PCVAD). The effectiveness of vaccination in reducing mortality attributed to the disease was determined on nine farms that met the New Zealand case definition for postweaning multisystemic wasting syndrome (PMWS), ...
متن کاملUpdate on Porcine Circovirus Related Diseases
Introduction Porcine circovirus type 2 (PCV2) is thought to be the cause of PMWS (postweaning multisystemic wasting syndrome), a condition affecting mainly pigs between 6 and 18 weeks of age. It is usually characterized by pigs that are wasting, do not respond well to conventional treatments and the mortality in those that get sick is high. Other clinical signs like thumping and diarrhea vary i...
متن کاملEar necrosis syndrome in weaning pigs associated with PCV2 infection: A case report
Porcine necrotic ear syndrome (PNES) in pigs has been reported as an increasing health problem in many countries with intensive pig farming. The etiology of this disease is complex and the presumed triggering factors can be divided into infectious and non-infectious agents. The present report describes a case of Porcine Circovirus type 2 (PCV2), infection associated with lesions of PNES at the ...
