Genome Sequence of Pasteurella multocida Razi 0002 of Avian Origin

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...

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...

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

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...

Virulence of Avian Serotype A1 Pasteurella multocida for Chickens and Mice.

The virulence of Pasteurella multocida (P. multocida) serotype A1 for chickens and mice was determined. Groups of chicken and mice were exposed intramuscularly and intraperitoneally to various concentration of P. multocida broth culture, respectively. This strain was highly virulent for chickens so that those exposed to only 7 c.f.u. of the organism died in less than 24 hours. Groups of mice ex...
