Persistence of porcine rubulavirus in experimentally infected boars

Veterinary Microbiology, 2013
Porcine rubulavirus is the etiological agent of blue eye disease in pigs. In boars, this virus causes orchitis and epididymitis and reduces seminal quality. The objective of this study was to determine the persistence of porcine rubulavirus in experimentally infected boars.

Immunity to porcine rubulavirus infection in adult swine

Veterinary Immunology and Immunopathology, 1998
The immune response against the porcine rubulavirus was analyzed in experimentally infected adult pigs. High titers of virus neutralizing and hemagglutinating inhibitory antibodies were identified in infected animals. The antibody specificity was directed towards HN, M, and NP rubula virion proteins; immunodominance of HN proteins was demonstrated ...

Experimental Porcine Rubulavirus (La Piedad-Michoacan virus) Infection in Pregnant Gilts

Journal of Comparative Pathology, 2004
Porcine rubulavirus (La Piedad-Michoacan virus) (PoRV-LPMV) is a member of the Paramyxoviridae family that causes encephalitis in young piglets and infertility in adult sows and boars. Infertility in sows naturally infected by PoRV-LPMV is characterized by an increased number of returns to oestrus, stillbirths and mummified fetuses. In this study, nine

NeuAcα2,3Gal-Glycoconjugate Expression Determines Cell Susceptibility to the Porcine Rubulavirus LPMV

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1997
Relevance of membrane sialoglycoconjugates as receptors for infection by the porcine rubulavirus has been determined in vitro by sugar and lectin competition assays and by inhibition of glycosylation. Our results show that NeuAc alpha 2,3Gal but not NeuAc alpha 2,6Gal inhibits the virus infectivity of Vero cells, and the virus was effectively blocked ...

Lesions in the reproductive tract of boars experimentally infected with porcine rubulavirus

Journal of Comparative Pathology, 1997
"Blue eye" disease of pigs in Mexico is caused by porcine rubulavirus and characterized by infertility in sows and boars, nervous signs in young pigs, and corneal opacity in pigs of all ages. The pathogenesis of reproductive tract lesions in rubulavirus-infected boars has not previously been investigated.

Molecular characterisation of Porcine rubulavirus (PorPV) isolates from different outbreaks in Mexico

Virus Genes, 2016
Since the report of the initial outbreak of Porcine rubulavirus (PorPV) infection in pigs, only one full-length genome from 1984 (PorPV-LPMV/1984) has been characterised. To investigate the overall genetic variation, full-length gene nucleotide sequences of current PorPV isolates were obtained from different clinical cases of infected swine.

Comparative evaluation of the CD4+CD8+ and CD4+CD8− lymphocytes in the immune response to porcine rubulavirus

Veterinary Immunology and Immunopathology, 2001
The porcine immune system is unique in the expression of CD4+CD8+ (double-positive, DP) lymphocytes. These cells have been associated with immunological memory due to their gradual increase with age, the expression of memory phenotype and their ability to respond to recall viral antigen.

Semen alterations in porcine rubulavirus-infected boars are related to viral excretion and have implications for artificial insemination

Research in Veterinary Science, 2007
Porcine rubulavirus (PoRV), also known as blue eye disease (BED) of swine, causes respiratory and reproductive problems in pigs at several developmental stages. To study the effect of PoRV infection on semen production, five boars were infected with 1 x 10(6) TCID(50)/ml of PoRV strain PAC-3 and evaluated for 59 days post inoculation (DPI).

Porcine Rubulavirus Lpmv Rna Persists in the Central Nervous System of Pigs After Recovery from Acute Infection

Journal of Neurovirology, 1998
In order to study persistence of the porcine rubulavirus LPMV, we examined tissue samples collected from pigs 53 days after experimental infection. These pigs survived the initial infection and could clinically be considered to have recovered from the infection.

Investigation of T-cell responses and viral mRNA persistence in lymph nodes of pigs infected with porcine rubulavirus

Veterinary Immunology and Immunopathology, 2009
Selected lymphocyte subpopulations were studied and the distribution of viral mRNA were investigated during acute and persistent porcine rubulavirus (PoRV-LPMV) infection in Vietnamese pot-bellied pigs. Six pigs infected with PoRV-LPMV at 17 days of age exhibited clinical signs 7-10 days post-inoculation (pi).
