Abstract

Mycoplasma hyopharyngis is a seldom isolated porcine species. It was found, adequately described, and named by [3]. In that study 7 strains were isolated from the upper respiratory tract of pigs in 2 different herds, one of which was an institutional herd. All the strains fulfilled the usual criteria put up for characterization of mycoplasmas. They could degrade the amino acid arginine, but pathogenic capabilities were not reported. They were found antigenically distinct from all other mycoplasmas, inclusive the recognised porcine species. A later report on the isolation of M. hyopharyngis was done by [2] who in a single swine herd on 2 occasions found the microorganism in inflamed joints and adjacent subcutaneous abcesses of some animals. In a later phylogenetic study [6] found that the mycoplasma belongs to the Mycoplasma lipophilum cluster within the Mollicutes.

Summary

Introduction

A zone of inhibition in mm. b distinct FITC colour of stained colonies mhu04652) but deviating by 10 bases from another M. hyopharyngis 16S rDNA sequence published in GenBank (Blank et al 1996, accession number: mhu58997). Mycoplasma hyopharyngis is a seldom isolated porcine species. Adequately described, and named by Erickson et al. In that study 7 strains were isolated from the upper respiratory tract of pigs in 2 different herds, one of which was an institutional herd.
