The aim of this study was to characterize Erysipelothrix sp. isolates from clinically affected pigs and their environment and compare them to the Erysipelothrix sp. vaccines used at the sites. Samples were collected during swine erysipelas outbreaks in vaccinated pigs in six Midwest United States swine operations from 2007 to 2009. Pig tissue samples were collected from 1 to 3 pigs from each si...

Inoculation of 200 mean egg infectious doses (EID(50)) of lentogenic Newcastle disease virus strain B1 (NDV-B1) into the air sac of 4-day-old specific-pathogen-free chicks provided significant protection against challenge of the air sac with 100 chicken mean lethal doses (LD(50)) of velogenic NDV-H but no protection against reinfection when the challenge was by the eye. Conversely, inoculation ...

Abstract Plasmodium vivax is the most common human malaria parasite in Asian countries including Pakistan. Present study was designed to explore genetic diversity of plasmodium genotypes based on Pvmsp-3α and Pvmsp-3βgenes using allelic specific nested PCR RFLP assays markers from field isolates district Mardan, Blood samples 200 P. malarial patients were collected after taking their written in...

Respiratory syncytial virus (RSV) is a major cause of respiratory tract infection in infants and young children worldwide, but currently no safe and effective vaccine is available. The RSV G glycoprotein (RSVG), a major attachment protein, is an important target for the induction of protective immune responses during RSV infection. However, it has been thought that a CD4+ T cell epitope (a.a. 1...

Strains of Newcastle disease virus (NDV) can be separated into genotypes based on genome differences even though they are antigenically considered to be of a single serotype. It is widely recognized that an efficacious Newcastle disease (ND) vaccine made with any NDV does induce protection against morbidity and mortality from a virulent NDV challenge. However, those ND vaccines do not protect v...

During June and July 1977 5 junior boys in a boarding school for 800 pupils became ill with a mild infection caused by Coxsackie B1. The school had been taking part in a vaccine trial, and paired blood samples had been taken from new entrants in October 1976 and October 1977. 18% of the boys susceptible to the infection developed antibodies. The results suggest that dormitories are more importa...

Zataria multiflora essential oil possesses immunomodulatory effects and the present study investigatesits effect on immune responses to live Newcastle disease (ND) vaccines and faecal shedding period ofvaccine strain virus in chickens. One hundred and eighty chickens from both sexes were divided into 6 equalgroups: group 1: unvaccinated, group 2: vaccinated (B1 vaccine followed by La Sota 10 da...

Newcastle disease virus (NDV) is an economically important poultry pathogen with a worldwide distribution that may infect a wide range of domestic and wild avian species. The identification of different pathotypes of NDVs plays an important role in the diagnosis and development of vaccines to control and eradicate NDV infections. In our previous study, we showed that mono-specific antibodies ca...

The genus Aeromona8 was established by Kluyver & van Niel (1936) for pseudomonads fermenting carbohydrates with the production ofcarbon dioxide and hydrogen. Since von Wolzogen Kiihr (1932) had previously shown that a xnember of this group, Pseudomonas fermentan8, gave a positive VogesProskauer reaction, the existence of a butylene glycol fermentation in the genus was suspected, although the ab...
