Phenotypic characterisation of Australian sheep and cattle isolates of Mannheimia haemolytica, Mannheimia granulomatis and Mannheimia varigena.
OBJECTIVE To perform a comprehensive phenotypic characterisation of 35 isolates of bacteria previously identified as haemolytic Pasteurella-Actinobacillus and obtained from cattle and sheep. DESIGN The 35 isolates that had been obtained from Australian animals, 30 from cattle and five from sheep, were compared with reference strains of the five recognised species of the genus Mannheimia--M. h...
متن کاملRapid detection of Mannheimia haemolytica in lung tissues of sheep and from bacterial culture
AIM This study was aimed to detect Mannheimia haemolytica in lung tissues of sheep and from a bacterial culture. INTRODUCTION M. haemolytica is one of the most important and well-established etiological agents of pneumonia in sheep and other ruminants throughout the world. Accurate diagnosis of M. haemolytica primarily relies on bacteriological examination, biochemical characteristics and, bi...
متن کاملComplete Genome Sequence of Mannheimia haemolytica Strain Mh10517, Isolated from Sheep in South Africa
Respiratory disease caused by Mannheimia haemolytica is a major concern in the cattle and small stock industry worldwide. This problem arises due to the interaction of numerous contributing factors, including physical stresses associated with weaning, shipment, inclement weather, and overcrowding coupled with viral and bacterial infections. The whole genome of M. haemolytica strain Mh10517 was ...
متن کاملMycoplasma ovipneumoniae can predispose bighorn sheep to fatal Mannheimia haemolytica pneumonia.
Mycoplasma ovipneumoniae has been isolated from the lungs of pneumonic bighorn sheep (BHS). However experimental reproduction of fatal pneumonia in BHS with M. ovipneumoniae was not successful. Therefore the specific role, if any, of M. ovipneumoniae in BHS pneumonia is unclear. The objective of this study was to determine whether M. ovipneumoniae alone causes fatal pneumonia in BHS, or predisp...
متن کاملAnalysis of in vivo expressed genes in Mannheimia haemolytica A1.
The expression of Mannheimia haemolytica A1 genes during in vivo growth was examined by reverse transcriptase-polymerase chain reaction (RT-PCR) using total RNA extracted directly from M. haemolytica A1 recovered from pneumonic lungs of cattle. Primers specific for three groups of genes were used. Group 1 includes virulence-related genes: lktC, tbpB, ahs, nmaA, gs60 and gcp. Group 2 includes ge...
