conclusions the clinical klebsiella strains isolated from lahore region, pakistan exhibited resistance to most commonly used antibiotics, which can be a serious threat to public health. the study reported some potential actinomycetes strains, which exhibit promising activity against multidrug resistant klebsiella strains. results the isolated klebsiella strains showed resistance against most of...
background: acinetobacter baumannii is an important opportunistic pathogen which causes complications in hospitalized patients, especially those in icu. the aim of this study was to determine the frequency of class 1 and 2 integrons in multi-drug resistance a. baumannii and to investigate the association between the presence of integrons and antibiotic resistance patterns. methods: a total of 4...
background and objectives: there is increasing emergence of multidrug resistant pseudomonas aeruginosa (mdrpa) strains and drug resistance is positively-correlated with biofilm-forming ability. since about 10% of p. aeruginosa genome is controlled by quorum sensing (qs), alteration in its antibiotic susceptibility by targeting qs was the focus of the present study. materials and methods : one d...
The nature of the broad substrate specificity phenomenon, as manifested by multidrug resistance proteins, is not yet understood. In the Escherichia coli multidrug transporter, MdfA, the hydrophobicity profile and PhoA fusion analysis have so far identified only one membrane-embedded charged amino acid residue (E26). In order to determine whether this negatively charged residue may play a role i...
Multidrug resistance is a serious obstacle encountered in cancer treatment. Since drug resistance in human cancer is mainly associated with overexpression of the multidrug resistance gene 1 (MDR1), the promoter of the human MDR1 gene may be a target for multidrug resistance reversion drug screening. In the present study, HEK293T cells were transfected with pGL3 reporter plasmids containing the ...
A critical risk to the continued success of antifungal chemotherapy is the acquisition of resistance; a risk exacerbated by the few classes of effective antifungal drugs. Predictably, as the use of these drugs increases in the clinic, more resistant organisms can be isolated from patients. A particularly problematic form of drug resistance that routinely emerges in the major fungal pathogens is...
Background and Aims: Acinetobacter baumannii (A. baumannii) is an important multidrug-resistant opportunistic pathogen frequently causing various nosocomial infections and is a serious threat to burn patients. These infections are usually caused by the outbreak strains. The aim of this study was to show antibiotic resistance pattern and molecular typing of A. baumannii genes isolates collected ...
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 ...
