genotyping of pasteurella multocida ovine and bovine isolates from iran based on pcr-rflp of omph gene

چکیده
pasteurella multocida (p. multocida), a gram-negative facultative anaerobic bacterium, is a causative animal pathogen in porcine atrophic rhinitis and avian fowl cholera. the outer membrane of gram-negative bacteria contains of many different protein in very high copy numbers. one of the major outer membrane, the h proteins have functional as high immunogenicity and antigenicity. in this study to increase information about epidemiology of ovine and bovine p. multocida, the 24 isolates from sheep and nine isolates from cattle were investigated by pcr-rflp analysis of the omph gene. in all 33 isolates, digestion of the amplified fragment of omph gene by using ecori, cfoi and hindiii produced 3, 5 and 3 different restriction patterns respectively. sixteen rflp patterns were found among 33 investigated p.multocida isolates. this study showed that, the pcr rflp based on omph gene is potentially a useful method for typing of p. multocida isolates from sheep and cattle. the rflp patterns of this gene exhibited extensive restriction site heterogeneity, which may be particularly suitable for fingerprinting of p. multocida isolates. considering omph protein as a protective immunogenic moiety of p. multocida, the results of this study showed a heterogenic bacteria and this means the possibility to produce a multivalent vaccine to be protective against diseases caused by this organism in sheep and cattle in iran.

متن کاملMolecular typing of avian Pasteurella multocida isolates from Iran by PCR-RFLP of OmpH gene
Molecular typing of twenty-five Pasteurella multocida isolates has been assessed by restriction fragment length polymorphism (RFLP) of a species-specific PCR assay. All of the P.multocida isolates were recovered from fowl cholera outbreaks in Northern provinces of Iran. Amplification was based on the gene ompH, encoding a major outer membrane protein (protein H). PCR with ompH primers amplified...

In this study, to increase information about the relationship between caprine and ovine isolates of Pasteurella multocida, 16S rRNA gene sequencing of 9 goats (5) and sheep (4) isolates were investigated. Also, capsular type and toxAgene presentation was studied in this paper. All isolates, except one, belong to capsular type A, and toxA+ strain distributed among strains were isolated from both...

The 16 somatic serotype type strains and 60 field isolates of Pasteurella multocida, representing various avian species and geographic regions in Hungary, were characterised by PCR-restriction fragment length polymorphism (PCR-RFLP) analysis of the ompH gene with DraI restriction endonuclease. The type strains yielded eight different (I-VIII) profiles. Strains whose PCR fragment was uncut by Dr...
متن کاملLPS-PCR typing of ovine Pasteurella multocida isolates from Iran based on (L1 to L8) outer core biosynthesis loci
Pasteurella multocida isa gram-negative bacterial pathogen that is causative agent of a wide range of diseases in many animal species and humans. Lipopolysaccharides (LPS) are an important virulence factor, minor changes to structure of which can exert dramatic effects on pathogenicity of P. multocida in its host. LPS can be used for the identification and classification of strains with somatic...
