Diagnosis of PRRS Virus
نویسندگان
چکیده
• Additional tests are available to actually determine the presence of the virus. These tests include immunohistochemistry staining (IHC), fluorescent antibody staining (FA), polymerase chain reaction (PCR), and virus isolation (VI). While a positive result on these tests indicates the virus is present in the sample, a negative test does not necessarily indicate that the pig is free of the virus. Correct sample selection, sample handling, and the sensitivity of the test all interact to provide a reliable result.

Review on the transmission porcine reproductive and respiratory syndrome virus between pigs and farms and impact on vaccination
Porcine reproductive and respiratory syndrome (PRRS) is considered to be one of the most costly diseases affecting intensive pig production worldwide. Control of PRRS is a complex issue and involves a combination of measures including monitoring, diagnosis, biosecurity, herd management, and immunization. In spite of the numerous studies dealing with PRRS virus epidemiology, transmission of the ...
متن کاملPorcine reproductive and respiratory syndrome (PRRS): a review, with emphasis on pathological, virological and diagnostic aspects.
Despite early attempts to control the spread of the disease, porcine reproductive and respiratory syndrome (PRRS) has now become endemic in many countries including Britain. The occurrence of subclinical herd infections, the prolonged circulation of virus within herds and probable aerogenic virus spread all mitigated against the success of control measures. The origin of the disease is unknown ...
متن کاملA brief review of procedures and potential problems associated with the diagnosis of porcine reproductive and respiratory syndrome.
Experience has shown that, for a number of reasons, a diagnosis of porcine reproductive and respiratory syndrome (PRRS) is sometimes difficult. In this review we discuss: (1) field observations and laboratory tests that are useful in arriving at a definitive diagnosis; (2) the impact of so-called atypical PRRS on diagnostic procedures in North America; (3) the means by which diagnostic problems...
متن کاملLaboratory diagnosis of porcine reproductive and respiratory syndrome (PRRS) virus infection
The Committee thanks Dr. Sagar Goyal for editorial assistance. Summary: Porcine reproductive and respiratory syndrome (PRRS) is a relatively new, economically important disease of pigs and is characterized by reproductive failure in sows and gilts, pneumonia in young growing pigs, and an increase in preweaning mortality. The PRRS virus (PRRSV) was initially isolated in the Netherlands and the U...
متن کاملEvaluation of contact exposure as a method for acclimatizing growing pigs to porcine reproductive and respiratory syndrome virus.
OBJECTIVE To determine whether 6.5-week-old gilts that have not previously been exposed to porcine reproductive and respiratory syndrome (PRRS) virus can be acclimatized to an endemic strain of the virus by commingling with age-matched gilts inoculated with the endemic PRRS virus strain and whether 10.5-week-old gilts can be acclimatized by commingling with age-matched inoculated or contact-exp...
متن کاملA retrospective study of risk factors for porcine reproductive and respiratory syndrome virus infection and clinical disease in swine herds in Illinois during the early years of the pandemic
Results: Larger herd size was associated with an increased risk, and isolation of purchased gilts with a decreased risk, of both PRRS virus infection and clinical PRRS. Purchase of semen for AI was associated with an increased risk of PRRS virus infection. Implications: Swine producers should certify that purchased semen is free of PRRS virus, gilts should be isolated prior to introduction to t...
