First report of extended-spectrum-beta-lactamase-producing Salmonella enterica serovar Kentucky isolated from poultry in Ireland.

Detection of Extended Spectrum Beta Lactamase Producing Salmonella spp. and Multidrug Resistance Pattern

  Background: and Objectives: Salmonella infections are endemic in many developing countries with poor sanitary conditions, but emerge sporadically as a serious public health threat in developed countries. Infections with multidrug resistant (MDR) strains of Salmonella have been associated with treatment failures. Salmonella spp. resistant to extended spectrum cephal...

Characterization of extended-spectrum beta-lactamase (TEM-52)-producing strains of Salmonella enterica serovar typhimurium with diverse resistance phenotypes.

Two Salmonella enterica serovar Typhimurium strains from different clonal origins, both producing an extended-spectrum beta-lactamase (TEM-52), were isolated from a patient. This enzyme was encoded on a single plasmid and was found at very low levels in one strain, while being encoded on multiple plasmids and in multiple different EcoRI fragments in the other strain.

CMY-2 beta-lactamase-producing Salmonella enterica serovar infantis isolated from poultry in Japan.

Salmonella enterica: Serotyping, Drug Resistance & Extended Spectrum of β-Lactamase (ESBLs)

Background & Objective: Genus Salmonella has more than 2400 serotypes. The two major groups are S.enterica and S.bongori. Important serotypes are situated in S.enterica group. Antibiotic therapy in salmonellosis is restricted to typhoid fever and acute infections. After the first reporting of resistance in S.Typhimurium DT 104, nowadays, developing of resistance in Salmonella, specially, ESBL p...

Two different extended-spectrum beta-lactamases (ESBLs) in one of the first ESBL-producing salmonella isolates in Poland.

Two extended-spectrum beta-lactamase (ESBL)-producing salmonella isolates, Salmonella enterica serovar Enteritidis and Salmonella enterica serovar Typhimurium, were analyzed. Both isolates produced the CTX-M-3 ESBL; however, their bla(CTX-M-3) genes were located on different plasmids. The serovar Typhimurium isolate also expressed another ESBL, SHV-2a, and probably the two ESBL genes had been a...
