چکیده

Tetracycline-resistant isolates of Pasteurella multocida and Pasteurella haemolytica obtained from various locations in the United States and Canada were studied to determine the distribution of the tet(H) gene. Of the 31 isolates examined, 25 were found to contain the tet(H) gene. Chromosomal or plasmid DNA obtained from those that did not contain the tet(H) gene did not hybridize with probes specific for classes A through G, though chromosomal DNA from one isolate lacking tet(H) hybridized with a probe specific for class M. The tet(H) gene was found on plasmid as well as on chromosomal DNA, suggesting that it is carried on a transposable element.

Molecular analysis of tetracycline resistance in Pasteurella aerogenes.

Tetracycline-resistant Pasteurella aerogenes isolates obtained from the intestinal tract of swine were investigated for their tet genes by PCR analysis and hybridization experiments. In contrast to Pasteurella isolates from the respiratory tract, tet(H) genes were detected in the chromosomal DNA of only 2 of the 24 isolates, one of which also carried two copies of a tet(B) gene. All other P. ae...

Diversity of tetracycline resistance genes in bacteria from Chilean salmon farms.

Twenty-five distinct tetracycline-resistant gram-negative bacteria recovered from four Chilean fish farms with no history of recent antibiotic use were examined for the presence of tetracycline resistance (tet) genes. Sixty percent of the isolates carried 1 of the 22 known tet genes examined. The distribution was as follows. The tet(A) gene was found in six isolates. The tet(B) gene was found i...

Phenotypic and genotypic characteristics of tetracycline resistant Acinetobacter baumannii isolates from nosocomial infections at Tehran hospitals

Objective(s):To date, the most important genes responsible for tetracycline resistance among Acinetobacter baumannii isolates have been identified as tet A and tet B. This study was carried out to determine the rate of resistance to tetracycline and related antibiotics, and mechanisms of resistance.  Materials and Methods: During the years 2010 and 2011, a total of 100 A. baumannii isolates we...

Distribution of virulence adhesion associated genes and antimicrobial susceptibility in Pasteurella multocida from ovine pasteurellosis in Iran

Pasteurella multocida is an opportunistic pathogen responsible for pneumonia of lambs and goats, respiratory atrophic rhinitis of swine. Although the molecular basis of the pathogenicity and host specificity of P. multocida is not well understood, several studies have reported that a number of proteins are correlated with the pathogenic mechanisms. Adhesins have a crucial role in mediating colo...
