“…The present finding is in agreement with the findings of various researchers who also recorded co-infection of PCV2 and PPV in various combinations in both pigs and wild boars (Sliz et al 2015;Saekhow et al 2016). Co-infections with all these targeted viruses (PCV2, PPV and CSFV) have recently been reported from India (Deka et al 2021).…”

Significance and Impact of the Study: The study reports the development and evaluation of a novel one-step triplex-PCR assay for simultaneous detection of three important viruses namely porcine circovirus type 2 (PCV2), porcine parvovirus (PPV) and classical swine fever virus (CSFV) involved in reproductive problems in pigs. As reproductive diseases cause significant economic losses in pig industry and under typical conditions of intensive pig production, it is common for pigs to be simultaneously infected with two or more viral pathogens, there is an urgent need for the development of diagnostic for simultaneous detection of several pathogens in a single reaction which will not only save time but also help in better management of diseases. The assay developed in this study will be very useful for identifying viruses in specimens from pigs with multiple infections.

“…The seroprevalence value found around the world varies greatly. An extensive study conducted in Asia (India) discovered that 1.24% of feral pigs are bred in the northeastern regions, while 39.1% are bred in Punjab state [ 39 ]. In Uganda, the seroprevalence varies depending on the district studied.…”

Porcine parvovirus (PPV) disease is a worldwide spread animal disease with high infection rate and serious impact on meat economy causing significant losses in livestock production. The purpose of this paper is to investigate and analyze the regional seroprevalence of PPV in Tibetan pigs in Tibet and evaluate risk factors related to the disease. A total of 356 serum samples of Tibetan pigs were collected from four counties and districts in Tibet, and anti-PPV antibodies were detected by using a commercial competitive ELISA. Our results show a seroprevalence of 91.01% (324 serum samples were found to be positive for anti-PPV antibodies). The positive rate among different district was 100%, 96.55%, 93.68% and 72.83%, respectively in the Mainling County, in Bayi district, Nang County and Bomê County. We found significant differences between different age and gender groups; particularly female animals show a seroprevalence of 96.03% while the males only 83.46%. From the perspective of the growth stage, our results indicate that subadults show a seroprevalence significative higher than other age groups (100%). This study describes for the first time the PPV seroprevalence among Tibetan pigs characterizing risk factors involved in its transmission and providing information to be taken into account for eventual surveillance or eradication plans.

Background: Postweaning multisystemic wasting syndrome (PMWS) is caused by porcine circovirus type 2 (PCV2). It is a globally emerging clinical condition which affects nursing piglets and growing pigs. PCV2 requires various cofactors for fully development of PMWS. The present report describes the pathology of PMWS associated with classical swine fever virus (CSFV), porcine parvo virus (PPV) and multidrug resistant enteric Escherichia coli infections in an organized swine farm, Rajasthan. In India, this is the first report on pathology of PMWS associated with all the three viruses and multidrug resistant enteric colibacillosis. Methods: Detailed necropsy was conducted on pig carcass submitted to Post-mortem Facility, Division of Pathology, ICAR-Indian Veterinary Research Institute (IVRI), Izatnagar in the year 2017 from an organized swine farm, Rajasthan, India. Heart blood and diarrhoeic intestinal contents were collected aseptically and stored separately at 4°C for bacteriological examination and antibiotic sensitivity test. Tissue samples were collected in sterile container and stored at -40°C for DNA and RNA extraction and polymerase chain reaction (PCR) and also collected in 10% neutral buffered saline for histopathological processing. Result: The organized farm was having history of 33% (200/600) of mortality among 2 months to 6 months old piglets. Gross lesions were wasting, lymphadenopathy, non-collapsed lungs, hydropericardium, hepatomegaly, icterus, enteritis and pale kidneys, button shaped ulcers in the caecum and colon etc. Histopathologically, lymphoid depletion, reticuloendothelial cell proliferation in lymphoid tissue, fibrin thrombi in spleen, severe hepatitis, interstitial pneumonia, interstitial nephritis, severe necrosis in large intestine, meningitis, perivascular cuffing (PVC), gliosis, neuronal degeneration in cerebrum etc were observed. Molecular diagnosis and bacteriological examination confirmed presence of PCV2, PPV, CSFV and multidrug resistant Escherichia coli.
