Validation of an Easy Handling Sample Preparation and Triplex Real Time PCR for Rapid Detection of T. equigenitalis and Other Organisms Associated with Endometritis in Mares.

Isolation and identification of Taylorella equigenitalis, the causative agent of contagious equine metritis, by bacteriology is laborious and does not permit differentiation from the other member of the genus, Taylorella asinigenitalis. Moreover, other organisms such as Klebsiella pneumoniae and Pseudomonas aeruginosa can also cause endometritis in mares and warrant diagnostic detection. Our objectives were to develop a rapid preparation method for field swab samples and to validate this protocol using new multiplex real-time polymerase chain reaction (rtPCR) detection tools for identification of these four pathogens.

Influenza A Virus Infection in Cats and Dogs: A Literature Review in the Light of the "One Health" Concept.

Influenza A viruses are amongst the most challenging viruses that threaten both human and animal health. Constantly evolving and crossing species barrier, the emergence of novel zoonotic pathogens is one of the greatest challenges to global health security. During the last decade, considerable attention has been paid to influenza virus infections in dogs, as two canine H3N8 and H3N2 subtypes caused several outbreaks through the United States and Southern Asia, becoming endemic.

The impact of porcine reproductive and respiratory syndrome virus genetic heterogeneity on molecular assay performances.

The remarkable economic losses due to porcine reproductive and respiratory syndrome (PRRS) have stated the control and eradication of this disease is one of the main issues of swine modern farming. The limited cross-protection of vaccine-induced immunity compelled the adoption of strict biosecurity measures that must be associated with the prompt diagnosis of infection. In our study four RT-PCR methods, a RT-PCR, a SYBR Green I and two hydrolysis probes, were compared to evaluate their respective benefits and disadvantages.

Distribution of Porphyromonas gingivalis fimA genotypes in isolates from subgingival plaque and blood sample during bacteremia.

Introduction: Porphyromonas gingivalis is considered as a major etiological agent in the onset and progression of chronic destructive periodontitis. Porphyromonus gingivalis fimA type has been correlated to the virulence potential of the strain; therefore this gene could be involved in the ability of P. gingivalis to reach blood stream.

Genotypic characterization of Porphyromonas gingivalis isolated from subgingival plaque and blood sample in positive bacteremia subjects with periodontitis.

Aim: The objective of this study was to investigate clonal relationship among Porphyromonas gingivalis isolated from subgingival plaque and blood samples in positive transient bacteremia subjects with periodontitis.

Material And Methods: Unrelated patients with general chronic periodontitis or general aggressive periodontitis requiring scaling and root planing (SRP) were included in the study. Genotyping of each isolate was performed using pulsed field gel electrophoresis technique.

Hypovirulent Listeria monocytogenes strains are less frequently recovered than virulent strains on PALCAM and Rapid' L. mono media.

Several selective media have been developed to detect Listeria monocytogenes contaminated foodstuffs. Polymyxin-acriflavine-LiCl-ceftazidime-aesculin-mannitol (PALCAM) and Oxford media, required for the EN ISO method 11 290-1, are used for the detection of Listeria spp. in 2 days based on the expression of esculinase activity.

Reliable ELISAs showing differences between resistant and susceptible lines in hens orally inoculated with Salmonella Enteritidis.

Reliable ELISAs were investigated with the aim to select hen lines resistant to Salmonella Enteritidis and producing high levels of antibodies. In the first experiment, the relation between the humoral response and the bacteriological results was assessed on hens from the Y11 resistant line and the L2 susceptible line, orally inoculated with 10(8) CFU S. Enteritidis per animal.
