Molecular analysis of OXA-48-carrying conjugative IncL/M-like plasmids in clinical isolates of Klebsiella pneumoniae in Ireland.

This study characterized an IncL/M-like plasmid containing a bla(OXA-48)-encoding gene from a clinical isolate of Klebsiella pneumoniae, denoted as E71T. Investigation of this plasmid sequence identified unique regions of interest along with conserved regions detected in eight other clinical carbapenem-resistant isolates. A 63-kb plasmid (pE71T) from K.

Further characterization of three Yersinia enterocolitica strains with a nalidixic acid-resistant phenotype isolated from humans with diarrhea.

Antimicrobial-resistant bacteria pose a threat to public health. Three Yersinia enterocolitica strains cultured from patients presenting with diarrhea and resistant to nalidixic acid were studied. Target gene mutations in gyrA alone were identified as part of the genetic basis for this phenotype.

Susceptibility of Campylobacter to high intensity near ultraviolet/visible 395±5nm light and its effectiveness for the decontamination of raw chicken and contact surfaces.

Campylobacter is an important cause of human gastroenteritis worldwide. Chicken meat is frequently contaminated with this organism and is considered to be a significant source of infection. It has been predicted that lowering the numbers of Campylobacter on chicken meat can reduce the risk to public health.

Effect of crust freezing applied alone and in combination with ultraviolet light on the survival of Campylobacter on raw chicken.

The application of crust freezing (CF) applied as a stand-alone treatment or in combination with ultraviolet (UV) light for reducing the level of artificially inoculated Campylobacter jejuni on raw chicken was investigated. CF air temperatures of -5, -15 and -27 °C (±3 °C) with freezing times of 70, 15 and 6 min, respectively, were used. The level of C.

Efficacy of high-intensity pulsed light for the microbiological decontamination of chicken, associated packaging, and contact surfaces.

The efficacy of high-intensity light pulse (HILP) technology (3 Hz, maximum of 505 J/pulse, and a pulse duration of 360 μs) for the decontamination of raw chicken and associated packaging and surface materials was investigated. Its ability to reduce microbial counts on raw chicken through plastic films was also examined. Complete inactivation of Campylobacter spp.
