Background & Objective: Klebsiella pneumoniae has received attention due to a wide range of diseases and antibiotic resistance.The resistance to fluoroquinolones in gram-negative bacteria is often due to chromosomal mutations in the gyr and par genes. This research aimed at investigating the pattern of fluoroquinolone resistance and its relation with a mutation in the parC gene among clinical i...
Industrial effluents consist many pollutant and heavy metals. Bacteria isolated from industrial west water ground may have potential to tolerate heavy metal. In this study we isolate a Citrobacter sp. which can resist heavy metal like Cu and Pb. Slurry from industrial west water ground was collected from 22.0663 N, 88.1041 E. The heavy metal content and other parameters of soil were estimated. ...
In this study, the antibiotic resistance (AR) of lactic acid bacteria (LAB) isolated from traditional Turkish fermented dairy products was investigated. Yogurt, white cheese, tulum cheese, cokelek, camız cream and kefir as dairy products were collected from various supermarkets. Lactic acid bacteria such as Lactobacillus spp., Streptococcus spp., Bifidobacterium spp., and Enterecoccus spp. were...
Abstract Background and objective: The periodic evaluation of antimicrobial activity of different antibiotic is essential because antibiotic sensitivity pattern may also changed during short courses. The aim of this study was to assess the frequency of Multi-drug Resistance (MDR) in Gram negative uropathogens. Material and Methods: This study was conducted on 111 gram negative uropatho...
Background and Aims: Microbial biofilms are responsible for 65% of human infections and antibiotic resistance. Therefore, finding appropriate ways to prevent infection and biofilm formation is essential. Medicinal plants are one of the suitable candidates to inhibit the antibiotics resistance particularly in biofilm forms. In this study, antimicrobial effects of T.C.P combined extracts (methano...
background: in this study, we determine the vector competence of musca domestica with reference to the transmission of susceptible and resistance bacterial strains in hospitals and slaughter house in sanandaj city, west iran. methods: totally 908 houseflies were collected to isolate bacteria from their external body based on standard procedures.antibiotic susceptibility testing was performed ...
The metal ion chemistry of macrocyclic ligands has now become a major subdivision of inorganic chemistry and is a growing area of research in inorganic and bioinorganic chemistry. The field of macrocylic chemistry of metals is developing very fast because of its applications and importance in the area of coordination chemistry. Macrocyclic ligands and their transition metal complexes have recei...
The aim of the present study was to evaluate the imipenem-resistant mechanism via the outer membrane protein (OMP) OprD2 and metal β-lactamase expression in the cell wall of Pseudomonas aeruginosa. The Pseudomonas aeruginosa was clinically separated and validated by VITEK-2 full-automatic bacteria analyzer. Drug resistance, sensitive antibiotics and minimum inhibitory concentration (MIC) were t...
Background: Multidrug-resistant (MDR) enterococci cause many problems for physicians and infection control specialists in the recent years. Hence, by the identification of antibiotic resistance patterns of enterococci in different geographical regions an appropriate strategy can be developed to prevent bacterial antibiotic resistance and provide effective treatment. The current study aimed at i...
