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....
conclusions this study demonstrated the co-existence of rmtc and blandm-1 genes for the first time in turkey. the spread of this resistant type should be monitored and limited through molecular surveillance. results twenty k. pneumoniae strains showed resistance to amikacin, and 40 were resistant to gentamicin. the mic value was found to be > 512 µg/ml in five amikacin-resistant strains and > 1...
Background and Objective: Staphylococcus aureus is one of the most important human pathogens and common causes of nosocomial and acquired infections in the world. The aim of this study was to investigate antibiotic resistance in methicillin-resistant S. aureus (MRSA) strains and the molecular properties of S. aureus strains. Materials and Methods: For this purpose, a descriptive study was perf...
Aims and Background: E. coli is a normal flora of the human and animal intestine that sometimes causes pathogenesis in the intestine and urinary tract. The aim of this study is to investigate resistance genes in E. coli isolated from toilets in the Islamic Azad University of Mashhad and perform genome sequencing in tetracycline-resistant strains. Methods: This cross-sectional study was perform...
Background and Objectives: Skeletal muscle mass depends on the balance between synthesis and degradation of muscle protein, which changes with aging and disease. The aim of the present reserch was to examine the effects of two exercise training protocols on alterations of some genes involved in pathways of protein synthesis and degradation in order to achieve a more effective training program i...
Background and purpose: Pseudomonas aeruginosa is an opportunistic pathogen in patients with chronic respiratory disease or in immunocompromised hosts. This bacterium shows intrinsic and acquired resistance to diverse antimicrobial agents. An important mechanism of resistance to fluoroquinolones in P. aeruginosa is the mutation in gyrA, a subunit of topoisomerases II. The aim of this study was ...
Background and purpose: High Resolution Melting curve analysis DNA (HRM) is one of the most sensitive and precise methods for detecting Staphylococcus aureus and resistance to Methicillin. The aim of this study was to analyze the HRM for detection of methicillin-resistant S. aureus strains. Materials and methods: In this experimental study, standard strains of S.aureus ATCC25923 and ATCC 33592...
Objective: The Rifampicin resistance and susceptibility of Mycobacterium tuberculosis are caused by mutations in the 81-base pair region of the rpoB gene encoding the b-subunit of RNA polymerase. Methods: Isoniazid resistance of M. tuberculosis is related to mutations in inha , oxyR and ahpC genes which 30 to 90 percent of Isoniazid resistance is occurred in 3015 codons of kat...
conclusions all the bacterial isolates were associated with a high resistance to various antibiotics and this resistant pattern could be confirmed by detection of a particular gene for each bacterium. objectives this study examined bacteremia in cancer patients from two medical centers regarding isolates and spectrum of antibiotic resistance pattern. patients and methods this was a prospective ...
