Population structure and diversity of avian isolates of Pasteurella multocida from Australia.

Genetic variations of avian Pasteurella multocida as demonstrated by 16S-23S rRNA gene sequences comparison

Pasteurella multocida is known as an important heterogenic bacterial agent causes some severe diseases such as fowl cholera in poultry and haemorrhagic septicaemia in cattle and buffalo. A polymerase chain reaction (PCR) assay was developed using primers derived from conserved part of 16S-23S rRNA gene. The PCR amplified a fragment size of 0.7 kb using DNA from nine avian P. multocida  isolates...

Prevalence of adhesion Virulence factor genes, antibiogram, and pathogenicity of avian Pasteurella multocida isolate from Iran

Pasteurella multocida possesses various virulence factors, including capsule, lipopolysaccharide, fimbriae, toxins, outer membrane proteins, and adhesions. Adhesins have a crucial role in mediating colonization and invasion of the host. The aim of the present study was to identify the prevalence of adhesion factor genes and resistance/sensitivity patterns among the avian P. multocida isolates f...

Characterization of Avian Pasteurella multocida Isolates by Protein Profiles and Restriction Enzyme Analysis of Chromosomal DNA

Characterization, ribotyping and capsular PCR typing of Pasteurella multocida isolated from Iranian sheep and goats

Pasteurella multocida is considered to be an important cause of ovine pneumonia and results causes considerable economic losses in Iran. Ribotyping PCR (Ribo-PCR) was used for investigating the diversity of ovine and caprine P.multocida. A total of 120 swab tonsil and nasal samples were obtained from sheep and goats. They were analyzed by biochemical tests and Ribo-PCR 16S-23S ribosomal RNA gen...

Polymerase chain reaction typing of Pasteurella multocida capsules isolated in Iran

Capsules from a range of pathogenic bacteria are the key determinants of virulency. The capsule hasbeen implicated in virulence of Pasteurella multocida. In this study a type-specific polymerase chain reaction(PCR) assay was used for capsular typing of 39 avian P. multocida isolates from Iran. The PCR amplified afragment of 1044 bp from all of tested isolates. It was found that all avian P. mul...
