To investigate the transition in concentration of porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) and antibody for these viruses in serum, serum samples were collected from 29 pigs on weaning day and at 7, 14, 21, 28, 53, 84, and 120 days after weaning.

Biochemical and multiplex-PCR analyses were used to identify Campylobacter spp. The minimal inhibitory concentrations of erythromycin, azithromycin, ciprofloxacin, nalidixic acid, gentamicin, and tetracycline for these organisms were determined

Quantitative analysis of the duration of foot-and-mouth disease virus (FMDV) RNA in tissues was carried out in pigs experimentally infected with FMDV O UKG 34/2001 and O SKR 1/2000.

An experiment was performed to investigate the effects of seaweed extracts, laminarin (derived ß-glucans) and fucoidan (sulphated polysaccharides) independently or in combination on post-weaning piglet performance and selected microbial populations.

Results of this study suggest for the first time occurrence of PPV and coinfection with PCV2 in crossbred Indian pigs affected with reproductive problem and neonatal mortality.

The extent to which early-life environment impacts on microbial diversity of the adult gut and subsequent immune processes has not been comprehensively investigated thus far. We addressed this important question using the pig as a model to evaluate the impact of early-life environment on microbe/host gut interactions during development.

The purpose of this study was to study the use of saliva samples as alternative to serum for acute phase protein (APP) quantifications in pigs at field conditions.

Invasion of endothelial cells is a virulence mechanism of H. parasuis that may be related to the ability of some strains to cause meningitis.

This study provides the first proof of concept for the prophylaxis/treatment of CSFV infection in pigs.

The cause of PWCS is unknown. Clinically, PWCS waxes and wanes in affected farms, and is not predictable. The majority of pigs with PWCS die, increasing mortality in 3 to 9 week old pigs from 1-2% to 6-10% on most affected farms.

A stochastic, mathematical model of a farrow-finish pig herd was developed and used to investigate the within-herd transmission dynamics of PRRSV, and to examine patterns of on-farm persistence and fade-out.

Twenty four pigs, weaned on the 28th day of life, were divided into4 groups. The control group was given feed without any acidifier preparation and the experimental groups were fed the same feed to which 10 g/kg of sodium formate, benzoic acid or fumaric acid was added.

Escherichia coli was isolated from the feces of 122 piglets with diarrhea on 55 farms in Korea. The virulence genes of each isolate were characterized by polymerase chain reaction (PCR).

To evaluate the bactericidal activity of seven commercial disinfectants against Lawsonia intracellularis using a tissue culture system.

The use of non-starch polysaccharides hydrolysis products in combination with egg yolk antibodies may reduce the effects of enterotoxigenic Escherichia coli K88

It has been demonstrated that PCV2 DNA can be detected in boar semen by PCR; however, the biological relevance of this is unknown.
