Characterization of extended-spectrum -lactamase-producing isolates of Haemophilus parainfluenzae

Isolation and molecular characterization of beta-lactamase-producing Haemophilus parainfluenzae from the genital tract.

Three Haemophilus parainfluenzae strains isolated from the urogenital tract harbored a beta-lactamase-coding 3.2-megadalton plasmid identical, by restriction endonuclease digestion and hybridization with radioactive and biotin-labeled probes specific for the TEM-1 beta-lactamase and TnA sequences, to the 3.2-megadalton "African-type" plasmid found in Neisseria gonorrhoeae.

Extended – Spectrum β-Lactamase Producing Klebsiella Species among Clinical Isolates

Extended – Spectrum Βeta-Lactamase producing strains among clinical isolates has been steadily increasing over the past years. Microorganisms responsible for UTIs such as Escherichia coli and klebsiella 5pp have the ability to produce ESBLs in large quantities. All the strains of klebsiella species in this study were collected from routine clinical samples confirmed by biochemical and other tes...

Further confirmation was done by slide agglutination using specific antisera (Denka-Seiken, Tokyo, Japan). Antibiotic susceptibility testing was done...

Prevalence of Multiple Drug Resistant Clinical Isolates of Extended-Spectrum Beta-Lactamase Producing Enterobacteriaceae in Southeast Iran

Background: Multidrug resistance and production of extended spectrum β-lactamases (ESBLs) by enteric gram-negative rods in hospitals and community continue to be worsened. We aimed to characterize the multidrug resistance and determine the prevalence of ESBL production by clinical isolates of Enterobacteriaceae in southeast Iran. Methods: Gram-negative bacteria isolated from clinical samples of...
