Detection of a bla(SHV) extended-spectrum {beta}-lactamase in Salmonella enterica serovar Newport MDR-AmpC.
Salmonella enterica serovar Newport MDR-AmpC expressing TEM-1b and extended-spectrum beta-lactamase SHV-12 was isolated from affected animals during an outbreak of salmonellosis that led to a 3-month closure of one of the largest equine hospitals in the United States.
متن کاملSalmonella 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...
متن کاملExtended-spectrum β-lactamase- and AmpC β-lactamase-producing D-tartrate-positive Salmonella enterica serovar Paratyphi B from broilers and human patients in Belgium, 2008-10.
OBJECTIVES To characterize the genetic determinants responsible for extended-spectrum cephalosporin (ESC) resistance of d-tartrate-positive Salmonella enterica subsp. enterica serovar Paratyphi B (serovar Paratyphi B dT+) strains that have emerged in poultry and humans in Belgium during 2008-10. METHODS The ESC resistance genes among non-redundant serovar Paratyphi B dT+ strains were determin...
متن کاملACC-1 β-Lactamase–producing Salmonella enterica Serovar Typhi, India
To the Editor: Typhoid fever, caused by Salmonella enterica sero-var Typhi, is a serious form of enteric fever. In 2000, the worldwide number of typhoid cases was estimated to be >21,000,000, and there were >200,000 deaths from this disease (1). Ciprofl oxacin is the fi rst-line drug of choice for treatment of patients with typhoid fever, but there has been an increase in strains resistant to c...
متن کاملA novel extended-spectrum TEM-type beta-lactamase, TEM-138, from Salmonella enterica serovar Infantis.
A novel natural TEM beta-lactamase with extended-spectrum activity, TEM-138, was identified in a ceftazidime-resistant clinical isolate of Salmonella enterica serovar Infantis. Compared to TEM-1, TEM-138 contains the following mutations: E104K, N175I, and G238S. The bla(TEM-138) gene was located on a 50-kb transferable plasmid. Expression studies with Escherichia coli revealed efficient ceftazi...
