Field evaluation of a quantitative polymerase chain reaction assay for Mycoplasma hyorhinis

A novel polymerase chain reaction assay to detect Mycoplasma genitalium.

AIMS To design and validate a polymerase chain reaction (PCR) assay targeting the 16S rRNA gene of Mycoplasma genitalium. METHODS Primers were designed that were complementary to the 16S rRNA gene sequence of M genitalium. After optimisation of the reaction conditions, the PCR was tested against nine M genitalium strains, a dilution series of M genitalium DNA, and a panel of common microorgan...

Polymerase Chain Reaction of Mgc2 and 16S rRNA Genes for Detection of Mycoplasma gallisepticum

Mycoplasmas are very small bacteria lacking cell walls that belong to various genera within the class Mollicutes, and also the smallest organisms that can live independently. They are able to cause serious and chronic disease because of some unique characteristics. Mycoplasma gallisepticum (MG) is an important avian pathogen causing significant economical losses within the poultry industry. The...

Field evaluation of a polymerase chain reaction-based nonisotopic liquid hybridization assay for malaria diagnosis.

In a blind field evaluation of a nonisotopic liquid hybridization assay for detection of malaria parasites, 100 blood samples were tested from an area in which malaria is endemic; light microscopy was used as the reference test. Sensitivity, specificity, and positive and negative predictive values of the hybridization assay were 100%. One sample that was microscopy-negative and hybridization-po...

A Diagnostic Multiplex Polymerase Chain Reaction Assay for Ocular Herpetic Infections.

Quantitative real-time polymerase chain reaction for detecting Mycoplasma hyosynoviae and Mycoplasma hyorhinis in pen-based oral, tonsillar, and nasal fluids

Mycoplasma (M.) hyorhinis and M. hyosynoviae are pathogens known to cause disease in pigs post-weaning. Due to their fastidious nature, there is increased need for culture-independent diagnostic platforms to detect these microorganisms. Therefore, this study was performed to develop and optimize quantitative real-time PCR (qPCR) assays to rapidly detect M. hyorhinis and M. hyosynoviae in pen-ba...
