background and aims: the indiscriminate use of antibiotics can lead to antibiotic resistance in the treatment of infections caused by bacteria such as pseudomonas aeruginosa. the presence of integrons in pseudomonas is clearly associated with multidrug resistances. therefore, this study aimed at tracking class i, ii and iii integrons of antibiotic-resistant isolates of pseudomonas aeruginosa th...

background: infection with non-typhoid salmonella (nts) is one of the most important health problems all over the world. antimicrobial drug resistance is increasing among salmonella infantis species. objectives: the aim of this study was to investigate the frequency of presence of class 1 integrons in s. infantis species as well as its association with drug resistance. materials and methods: th...

BACKGROUND/AIM Pseudomonas aeruginosa is the cause of 10% of hospital-acquired infections. The organisms are often multidrug- resistant, mediated mostly by antibiotic-resistant integrons. The aim of this research was to study integron carriage and its association with multidrug resistance in burn and nonburn clinical isolates of P. aeruginosa. MATERIALS AND METHODS A total of 112 P. aeruginos...

Phenotyping and genotyping have been carried out on 64 epidemic and sporadic isolates of Shigella sonnei identified in Italy in the years 2001 to 2003. Class 2 integron carriage has been also investigated. Isolates from four of the five outbreaks and four of six sporadic cases were biotype g, pulsed-field gel electrophoresis type B, and class 2 integron positive, suggesting emergence and spread...

Integrons are associated with a variety of gene cassettes, which confer resistance to multiple classes of antibacterial drugs. In this study we tested the frequency of class 1 and 2 integrons among multidrug-resistant Acinetobacter baumannii (MDRAB) clinical isolates. One hundred clinical isolates of A. baumannii were screened for carriage of class 1 and 2 integrons by PCR method. Results showe...

BACKGROUND Shigella spp. are major cause of diarrhoeal disease in both developing and developed countries. Shigella sonnei is the serogroup of Shigella most frequently responsible for sporadic and epidemic enteritis in developed countries. In recent years the emergence and spread of S. sonnei biotype g carrying class 2 integron have been frequently reported in many countries. Recently, S. sonne...

background: infections caused by pseudomonas aeruginosa or acinetobacter baumannii are of greatest concern for hospitalized patients, particularly those in intensive care units (icus). the aims of this study were to investigate the prevalence of integrons and biofilm formation among p. aeruginosa and a. baumannii isolates collected from icu and non-icu inpatients. materials and methods: a total...

Extensive use of antibacterials in clinical practice has been associated with increasing frequency of multi-resistant E. coli strains. Genetic elements such as Class 1 integrons have an important role in resistance development. In the current study, a total of 84 E. coli clinical isolates from Mansoura hospitals patients in Egypt were screened for antibacterial susceptibility against 12 differe...

Integrons by means of horizontal gene transfer carry multidrug resistance genes (MDR) among bacteria, including E. coli. The aim of this study was to determine the antibiotic resistance profiles and the genes associated with them, to gain insights in the distribution of phylogroups, prevalence, and characterization of class 1, 2 and 3 integrons among Enteropathogenic E. coli (EPEC) isolates, fr...

background: integrons are the major reasons of multidrug resistance (mdr) among enteropathogenic bacteria. occurrence of horizontal gene transfer between integron-carrying microorganisms and other enteric bacteria may increase the rate of emergence of integron-associated antibiotic resistance. objectives: the objective of this study was to investigate class 1 integrons among members of enteropa...
