Phenotypic and molecular typing of Salmonella strains reveals different contamination sources in two commercial pig slaughterhouses36726
slaughterhouse, 70% of the carcasses were contaminated, and only in 4% was the same genotype or serotype detected as in the feces of the corresponding pigs. The other positive carcasses in both slaughterhouses were ...
Evaluation of tests for antibodies against bovine herpesvirus 1 performed in national reference laboratories in Europe.
the virus neutralisation test and the gB-specific ELISA s were most sensitive for the detection of antibodies in serum, whereas for assaying milk samples the indirect ELISA s were the tests of choice. ...
Analytical performance of several classical swine fever laboratory diagnostic techniques on live animals for detection of infection.
evaluated. The RT-nPCR detected the highest proportion of infected pigs (98.9%), whereas the Antigen ELISA gave the worst detection results (74.7%). Within the group of test positive animals, infection was ...
Immuno-quantitative polymerase chain reaction for detection and quantitation of prion protein.
Immunosorbent Assay Humans polymerase chain reaction Prions Sensitivity and Specificity Abstract: Immuno-polymerase chain reaction (PCR) is an extremely sensitive detection method, combining the specificity of ...

Induction of in vivo functional Db-restricted cytolytic T cell activity against a putative phosphate transport receptor of Mycobacterium tuberculosis.
IFN-gamma ELISPOT responses to this epitope were also detected in tuberculosis-infected mice. The CD4 (+) and CD8 (+) T cell epitopes defined for PstS-3 were completely specific and not recognized in mice ...
Assessment of the cell-mediated immune response in chickens by detection of chicken interferon-gamma in response to mitogen and recall Newcastle disease viral antigen stimulation.
with the inactivated vaccine showed a specific response 4 weeks after vaccination. No significant proliferative responses to either NDV vaccine were detectable during the 4 weeks of the study. From our ...
Antimicrobial drug resistance in nontyphoid human Salmonella in Belgium: trends for the period 2000-200236738
detected in three S. Typhimurium isolates and sequencing of the gyrA gene revealed for each isolate two mutations at codons corresponding to Ser-83 and Asp-87. Multiresistance was also common in S. Virchow ...
Effect of challenge dose and age in experimental infection of pigs with encephalomyocarditis virus.
20-day-old pigs. Viraemia, and nasal and faecal excretions were detected in all groups and lasted 1-3 days, except for the 105-day-old pigs whose symptoms lasted for an additional day. Health Topics: Animal ...
