It is known that Aeromonas spp. possess different chromosomal β-lactamase genes. Presence and phenotypic expression of bla TEM, bla SHV, and bla CTX-M ESBL-encoding genes were investigated in environmental water isolates of Aeromonas hydrophila and Aeromonas jandaei. Presence of bla SHV and bla CTX-M genes was not observed, and bla TEM gene was verified in 91% of the isolates. Sequencing of 10 ...
Rapid identification of specific TEM-type β-lactamase genes in bacterial infections is important for determining appropriate clinical treatment. We report here the design and initial testing of a molecular diagnostic assay capable of amplifying a large segment of the blaTEM gene, as well as detecting widely spaced extended-spectrum β-lactamase (ESBL) mutations and inhibitor-resistant TEM (IRT) ...
Abstract Introduction and objective: Urinary tract infections (UTIs) is one of common infections in children which rapidly acquiring more resistance to antimicrobial drugs in the worldwide. The aim of this study was to evaluate the frequency of SHV, TEM and CTX-M genes in Escherichia Coli and Klebsiella Pneumoniae strains isolated from UTI in children in 17 Shahrivar hospital from Rasht city....
Ceftazidime-resistant Klebsiella pneumoniae strains began to appear when ceftazidime usage was increased in two unrelated Chicago hospitals. These strains produced a beta-lactamase with an isoelectric point of 5.6 (RP-5.6) and strong hydrolyzing activity against ceftazidime. Two different restriction digest profiles were associated with the ceftazidime resistance plasmids. A second beta-lactama...
The aim of this study was to investigate the existence of a β-lactamase gene in a group of multi-drug resistant Acinetobacter baumannii. Twenty strains of multi-drug resistant A. baumannii were isolated. Thirty-four β-lactamase genes and the ISaba1-OXA-23 linkage were analyzed in these strains by polymerase chain reaction (PCR) and verified by DNA sequencing. Three kinds of β-lactamase genes (T...
Background: Escherichia coli (E.coli) bacteria are member of Enterobacteriaceae which are one of the common causes of urinary tract infections. Beta-lactamase enzymes are important factors for antibiotic resistance of beta-lactam family in gram-negative bacteria. According to increasing rate of urinary tract infections due to antibiotic resistant E. coli, the aim of this study was to study the ...
Angiogenesis plays a key role in tumor growth and cancer progression. TIE-2-expressing monocytes (TEM) have been reported to critically account for tumor vascularization and growth in mouse tumor experimental models, but the molecular basis of their pro-angiogenic activity are largely unknown. Moreover, differences in the pro-angiogenic activity between blood circulating and tumor infiltrated T...
conclusions the alcoholic extract of p. harmala was very effective against the selected esbl-producing e. coli isolates harboring the tem gene. therefore, it could be suggested as an antibacterial agent in the future. more researches are necessary for detecting the mechanism of this plant’s behavior and its pharmacological effects. results results of this study showed that in disk diffusion met...
beta-Lactamase production was investigated in cultures of 25 Klebsiella pneumoniae isolates isolated at a hospital in Durban, South Africa, in 1994 and 1996. Twenty of these isolates gave ceftazidime MIC/ceftazidime plus clavulanate MIC ratios of >/=8, implying production of extended-spectrum beta-lactamases (ESBLs), and DNA sequencing identified an ESBL gene (bla(TEM-53)) in a further two isol...
Isoelectric focusing and molecular hybridization with a TEM DNA probe were used to screen for TEM beta-lactamase in 328 bacterial isolates representing 11 gram-negative genera. The TEM enzyme was detected in 50% of isolates, and nine additional types of beta-lactamase could be identified in 36.9% of isolates. The TEM gene was detected in 53.6% of isolates. The results obtained by both methods w...
