Redesign and Validation of a Real-Time RT-PCR to Improve Surveillance for Avian Influenza Viruses of the H9 Subtype.
for molecular-based diagnostic methods and was the cause for suboptimal detection and false negatives during routine diagnostic monitoring. Starting from a dataset of sequences related to viruses of ...
Evaluation of mycobacteria-specific gamma interferon and antibody responses before and after a single intradermal skin test in cattle naturally exposed to M. avium subsp. paratuberculosis and experimentally infected with M. bovis.
resulted in a false positive M. bovis specific IFN-γ and antibody response after SIT in one of the two control animals (which remained negative in skin-test). Service: Veterinary bacteriology Bactériologie ...
Discrimination of three genetically close Aspergillus species by using high resolution melting analysis applied to indoor air as case study.
nor false negatives were observed during the performance assessment including 20 strains of Aspergillus. The limit of detection was determined for each species i.e., 0.5 pg of gDNA for A. creber and A. ...
Detection and characterization of Brucella spp. in bovine milk in small-scale urban and peri-urban farming in Tajikistan.
real-time PCR results highlight the need to further investigate whether there is a need for implementing complementary diagnostic strategies to detect false serological negative individuals in Brucella ...
Clinical problems due to encephalomyocarditis virus infections in two pig herds.
conventional gel-based polymerase chain reaction tests. The real-time PCR test that gave initially negative result was further optimized to avoid false negative results. CONCLUSIONS: Typical lesions are not ...
Evaluation of 3 rapid influenza diagnostic tests during the 2012-2013 epidemic: influences of subtype and viral load.
for A(H3N2), and only the bioNexia test had 1 false-negative result. Lowest sensitivities were observed for influenza B/Yamagata, (56.86% for BinaxNOW and Directigen and 39.21% for bioNexia). The ...

Simultaneous detection of bluetongue virus RNA, internal control GAPDH mRNA, and external control synthetic RNA by multiplex real-time PCR.
become the method of choice for routine viral diagnosis. As false-negative test results can have serious implications; an internal/external control system should be incorporated in each analysis to detect ...
