Background and purpose: Pseudomonas aeruginosa is one of the most important pathogens of burn infections in hospitals. It causes infection by producing some virulence factors such as exoS and exoT cytotoxins. The aim of this study was to evaluate the frequency of exoS and exoT genes among P.aeruginosa isolated from wound infections in burn patients and the relationship between the presences of ...
Background: By acquiring resistance and through new mechanisms, Acinetobacter baumannii has turned into a global problem in nosocomial infections. The present study was conducted to determine the frequency of resistant strains and resistance genes and also molecular typing of hospital strains in the city of Zanjan. Materials and Methods: A total of 250 clinical samples isolated from hospitaliz...
Background and Objective: Acinetobacter baumannii is considered as an important agent in nosocomial infections. The problem facing the tratment of these bacteria is increasing resistance to antimicrobial agents such as carbapenems. The main mechanism of resistance to carbapenems in these bacteria is the presence of oxacillinases genes, which belong to class D betalactamases. The aim of this st...
Background: Pseudomonas aeruginosa is a leading cause of Hospital-acquired infection worldwide. A major problem in the treatment of bacterial infections is the emergence of strains with multiple resistances (MDR). The aim of this study was to identify virulence genes lasB, toxA, algD, exos in Pseudomonas aeruginosa isolates from human and animal by Multiplex-PCR method and determination of anti...
this study aims at molecular identification of salmonella infantis isolated from backyard chickens and the detection of their antibiotic resistance genes. a total of 46 salmonella-suspected samples isolated from backyard chickens of northern iran were collected. serotyping was done by the traditional method and then confirmed by pcr. antimicrobial susceptibility of the isolates against 13 antim...
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: Klebsiella species are common causes of nosocomial, ulcers, blood and urinary tract infections, and also acquired pneumonia from the hospital and various intra-abdominal infections. Bacterial resistance mechanisms against antibiotics are different, but one of these resistance mechanisms, which is very problematic, is the production of β-lactamase enzymes in bacteria. The aim of this...
Background and Aims: The aim of this study was to determine the virulence and antibiotic resistance properties of Streptococcus agalactiae (S. agalactiae) and Streptococcus uberis (S. uberis) isolated from the ruminant’s sub-clinical mastitic milk in Iran. Materials and Methods: Positive samples in the CMT test were cultured and S. agalactiae and S. uberis have been identified using bi...
Background and Aims: The indiscriminate use of antibiotics can lead to antibiotic resistance in the treatment of infections caused by bacteria such as Pseudomonas aeruginosa. The presence of integrons in Pseudomonas is clearly associated with multidrug resistances. Therefore, this study aimed at tracking class I, II and III integrons of antibiotic-resistant isolates of Pseudomonas aeruginosa th...
