background: tuberculosis is one of the infectious diseases worldwide that has resurgence by the aids epidemic and led to the rise of drug-resistant tuberculosis patients. thus, it seems essential to monitor the drug susceptibility in tuberculosis patients. the new high resolution melting (hrm) method is simple, rapid and inexpensive for detection of the mutations responsible for drug resistance...
Introdution: Adiponectin is a peptide secreted from fat cells that plays an important role in the development of insulin resistance and type 2 diabetes. A number of single nucleotide polymorphisms in the adiponectin gene are associated with lower adiponectin expression and T2DM. The aim of this study was to determination the frequency of rs 2241766 polymorphism in adiponectin gene and its relat...
Background and Objective: Quorum sensing (QS) phenomenon, promoters involved in this pathway and the effect of these promoters on the expression of some structural genes, such as agrA and PII, could reveal the proper activity and gene expression of antibiotic resistance in S. aureus. The aim of this study was defining the relationship between promoter-dependent Quorum Sensing induced genes and ...
Background :Nowadays beta lactamase-producing multiple-drug resistance Klebsiella pneumoniae is as an important factor in nosocomial infections which has produced therapeutic difficulties in worldwide. The purpose of this study was to identify KPC-producing K. pneumoniae (blakpc) in clinical samples in Iran. Materials and Methods: After identification of isolates in species level using cultura...
conclusions methicillin resistance is a specialized concern in clinical studies, and it is mandatory to detect this mechanism by an accurate method that is updated periodically. increasing the resistance of s. aureus to multiple antibiotics underlines the need for intermittent resistance surveillance. results methicillin resistance was detected in 38% of s. aureus isolates, confirmed by the aga...
Background & Objective: Gastroenteritis is one of the most common Salmonella infections in human which is caused by Salmonella serotypes especially S.enteritidis and S.typhimurium. The spread of multi-drug resistant (MDR) Salmonella strains is a serious global issue. Obtaining integrons is considered as one of the most important factors in multi-drug resistance among gram-negative microorganism...
conclusions the result of this study showed a high prevalence of class 1 integron gene in most p. aeruginosa strains isolated from different parts of the environment and equipment used in icu. the role of these transferable genetic agents has been proven in the creation of resistance. so, the environmental bacteria represent a reservoir for dissemination of clinically relevant multidrug-resista...
tuberculosis is an infectious disease caused by mycobacterium tuberculosis and is the primary cause of mortality in the world. m. tuberculosis strains are important intracellular pathogens causing infection in oxygen-rich macrophages in the lungs. the emergence of aids, declined socioeconomic standards and a lessened emphasis on tb control programs have contributed to the disease resurgence. re...
background: nowadays, nosocomial infection with multidrug-resistant acinetobacter is an important problem in the world, which is facing wide spectrum antibiotics and hence has become resistant. m aterials and methods: in this study, positive cultures of acinetobacter from one hundred clinical samples in seven hospitals from tehran during 2012-2013 were collected for checking antibiotic suscepti...
