The spread of antibiotic resistant bacteria throughout the food chain constitutes a public health concern. To understand the contribution of fresh produce in shaping antibiotic resistance bacteria and integron prevalence in the food chain, 333 antibiotic resistance Gram negative isolates were collected from organic and conventionally produced fruits (pears, apples, and strawberries) and vegetab...

The presence of integrons was assessed in gut bacteria isolated from wild-caught prawns. A pseudomonad was recovered that contained a Tn402-like class 1 integron with a complete transposition module and two gene cassettes. One cassette was identical to a previously described cassette from a chromosomal class 3 integron in Delftia tsuruhatensis.

OBJECTIVES VIM-type enzymes are among the most widespread acquired metallo-β-lactamases among Gram-negative pathogens. Integron In70 is a class 1 integron that has emerged as a successful genetic support for blaVIM-1 (one of the most prevalent blaVIM allelic variants) in Gram-negative non-fermenters, and is usually chromosome borne. The objective of this study was to characterize plasmid pAX22 ...

background and objectives: klebsiella species are of the most common bacteria involved in nosocomial and urinary tract infections. genetic elements such as class 1 integrons have an important role in the resistance development. in this study, the share of class 1 integrons, the genetic characterization of the integron cassettes and pfge profiles of the clinical klebsiella isolates are evaluated...

The present study was aimed to determine the prevalence and characteristics of Salmonella isolated from meat samples of commercial broilers (CB) and spent hens (SH). Between March and June 2016, 200 retail raw chicken carcasses (100 from CB and 100 from SH) were obtained from local supermarkets in Tai'an city of China, and Salmonella isolates were then analyzed for antibiotic resistance, seroty...

OBJECTIVES We analysed the architecture and probable origin of a class 1 integron from cefotaxime-resistant Morganella morganii isolates. METHODS bla genes and class 1 integron elements were detected by PCR and DNA-DNA hybridization in a M. morganii strain isolated in 1996. PCR-mapping and sequencing of different fragments were carried out to determine the integron's architecture. RESULTS A...

OBJECTIVES Vibrio cholerae O1 from a 2006 outbreak in Accra were commonly resistant to multiple antimicrobials and, in particular, to trimethoprim/sulfamethoxazole, drugs commonly used in the treatment of cholera. We sought to determine the genetic basis for trimethoprim/sulfamethoxazole resistance in outbreak isolates. METHODS Twenty-seven isolates from the outbreak were screened by PCR and ...

BACKGROUND Acinetobacter baumannii (A. baumannii) has emerged globally as a significant pathogen in hospitals. It is also present in soil and water. In a previous study, we discovered that the A. baumannii class 2 integron occurred most frequently. Here, we determined whether the A. baumannii class 2 integron is in the soil around our hospital, and if the soil is the cause for increasing number...
