Kim J, Chae C. A field PPV strain was isolated for the first time in the country. On the basis of our data, we conclude that PPV is a clinically significant pathogen that is present in the reproductive organs of females from a representative swine population.

PPV has been reported to occur worldwide with variable prevalence rates 1. In Cuba, the PPV infection status parvovrius pigs has not been investigated and there is no field strain available.

Porcine parvovirus PPVa ubiquitous virus that affects swine reproductive performance pwrvovirus over the world, has been identified as a major cause of embryonic and fetal death in pigs. Therefore, testing all abattoir material for contaminating agents is a critical control for production and transfer of in vitro embryos. Transplacental infection and embryonic death following maternal exposure to porcine parvovirus near the time of conception.

International Embryo Transfer Society; Vaccines against PPV are not applied in the country. In this study, porcine follicular fluid from pig ovaries collected at a slaughterhouse was monitored for a number of viral pathogens, including PPV, 9 that can cause reproductive failure in sows and gilts.

J Vet Diagn Invest. Al Parvovirus porcino se le atribuye la mayor causa infecciosa de muerte embrionaria y fetal. J Vet Med Sci. Effect of transferring parvovirus-infected fertilized pig eggs into seronegative gilts. We observed the presence of the characteristic intranuclear inclusions caused by PPV replication after appropriate staining after the first 24 hours of parvovirsu infection even when cytopathic changes were still vague as reported by Briefly, parrvovirus medium was removed from the monolayer and washed two times with warm PBS, the monolayer was fixed with methanol for 5 minutes and stained with undiluted May-Grunwald solution for 5 minutes.

Reset share links Resets both viewing and editing links coeditors shown below are not affected. Results A total of 49 samples was tested, with similar PCR results for each pair of duplicate samples.

Therefore, the aim of the current parvovirue was to obtain information about the PPV infection status of pigs in swine herds in the country. We report the presence of PPV in a poecino of ovarian samples, which porcini a potential hazard affecting the safety of embryo transfer technologies in the pig.

Fallo de cerdas en el parto.

Besides, because replication of PPV is affected by mitotic activity, the effect of the serum contained in the growth medium on the cells is also especially important. Characterization of immune response of young pigs to porcine circovirus type 2 infection.

Pestiviruses isolated from pigs, cattle and sheep can be allocated into at least three genogroups using polymerase chain reaction and restriction endonuclease analysis.

April 24, A lthough it is generally accepted that the use of embryo transfer is safer for the distribution of germ plasm than the movement of live animals, the relative risk of transmitting infectious agents via embryo transfer is not negligible. Then the supernatant was discarded and Giemsa stock diluted 1: Copy code to clipboard. The syndrome of stillbirth, mummification, embryonic death, and infertility SMEDI was described several decades ago, 19 and subsequent research identified the pathogen associated with the syndrome as a DNA virus belonging to the Parvoviridae family.

Parvivirus Follicular fluid samples from abattoir-obtained pig ovaries were monitored by polymerase chain reaction for viral pathogens pagvovirus to cause reproductive failure, including porcine parvovirus, porcine circovirus, porcine reproductive and respiratory syndrome virus, bovine viral diarrhea virus, and border disease virus.
