Pasteurella multocida is an opportunistic pathogen responsible for pneumonia of lambs and goats, respiratory atrophic rhinitis of swine. Although the molecular basis of the pathogenicity and host specificity of P. multocida is not well understood, several studies have reported that a number of proteins are correlated with the pathogenic mechanisms. Adhesins have a crucial role in mediating colo...
Background & Objectives: Escherichia coli is the most common agent of urinary tract infections, with P fimbriae as the most important virulence factor. Uropathogenic Escherichia coli expresses various types of adhesive genes such as P fimbriae and pyelonephritis-associated pili (PAP), which mediate the binding to the surface of epithelial cells in the urinary tract. This study aimed to iden...
the prevalence of icaadbc genes among clindamycin inducible resistant staphylococcus aureus isolates
background: clindamycin inducible resistant staphylococcus aureus (s.aureus) isolates can cause failure in treatment with this antibiotic. biofilm production via polysaccharide intercellular adhesion (pia) contributes in the colonization of s. aureus, resulting in the initiation of different diseases. the aim of this study was to detect icaadbc genes among isolates of s.aureus with inducible re...
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 katg gene. the rpob a...
background: quaternary ammonium compounds (qac), which contain benzalkonium chloride as the most widely used agent, are employed as wound and skin antiseptics, as well as disinfectants in hospitals. the resistance mechanism to disinfectants is usually determine by genes which are related to resistance to quaternary ammonium compounds, namely, qace, qacδe1, qacδe1 that are found in gram-negative...
The emergence of multidrug resistance (MDR) and extensively drug resistance (XDR) in Acinetobacter baumannii has made an important challenge in the treatment of infections caused by this organism. The ability of carbapenemase production is one of the main mechanisms for the emergence of MDR and/or XDR in A. baumannii. The aim of this study was to detect carbapenemase producer A. baumannii. In t...
Background: Klebsiella pneumoniae is an opportunistic microorganism causing nosocomial infection all over the world .This study aimed to investigate the prevalence of biofilm formation in K. pneumoniae isolated from patients and its correlation with the virulence factors. Materials and Methods: Biochemical tests were used for the identification of K. pneumonia isolated from patients referred to...
Background: Listeriosis can be fatal for vulnerable groups of society. The disease has been widespread in recent years due to the large consumption of dairy and meat products. There is little information about the susceptibility of antibiotics and the pattern of Listeria monostigenesis gene resistance in Iranian society. Accordingly, the present study was conducted to investigate the antibiotic...
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....
Background and Purpose: Candida albicans (C. albicans) is an opportunistic fungus that can colonize women’s mucosal epithelial cell surfaces, causing vulvovaginitis in specific circumstances. The major genes contributing to drug resistance in C. albicans are the candida drug resistance (CDR) and multi drug resistance (MDR) genes. The purpose of this study was to evaluate the CDR-2 and MDR...
