Background and Objective: Klebsiella pneumoniae is one of the three pathogens that has become a global disease control and treatment problem due to its resistance to common antibiotics. For this reason, it is crucial to study the genes that cause antibiotic resistance in it. Therefore, the aim of this study was to investigate the phenotypic and genotypic frequency of tetracycline resistance in ...

Background: The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and patter...

Introduction: Acinetobacter baumannii, a known causative agent of nosocomial infections, is one of the highly antibiotic-resistant gram-negative bacilli. Carbapenem-resistant Acinetobacter isolates are increasingly reported worldwide. Carbapenems such as imipenem and meropenem are efficient antimicrobial agents commonly used for the treatment of infections caused by multi- resistant A. baumanni...

Candida albicans has the ability to change between yeast and hyphal cells and is known to be a virulence property. Efg1gene of C.albicans is as a main transcription factor that plays pivotal roles in biofilm formation The aim of the current study is to investigate the presence of Efg1 gene in Candida albicans isolates from women with vaginal candidiasis and its impact on biofilm formation.We us...

BACKGROUND: Salmonellosis is one of the most importantzoonotic diseases throughout the world. OBJECTIVES: Thepurpose of this study was to characterize a large collection ofSalmonella isolates from different poultry sources in Iran.METHODS: A total of 123 Salmonella isolates from differentpoultry sources were subjected to drug susceptibility test,hemolysin production, motility test, and plasmid ...

Background and Objective: Biofilm formation plays a crucial role in wound infections and increases the bacteria resistance to treatment. The present study investigated the relationship between the biofilm formation, ESBL, AmpC, and KPC enzymes in Acinetobacter baumannii isolated from the wound specimens. Materials and Methods: Eighty- nine A. baumannii isolates were collected from wound specim...

Background: Stenotrophomonas maltophilia is an opportunistic bacterium, contributing to different hospital-acquired infections and can be acquired from different hospital setting sources. Epidemiological study of S. maltophilia in the hospital also demonstrates the intrahospital distribution of certain strains of bacteria in healthcare facilities. The aim of the current study was to identify th...
