conclusions the results showed that e. coli isolated from patients with uti had eight virulence factors with high frequencies. moreover, these results alleged a direct connection between virulence factors and antimicrobial resistance in e. coli. results the frequency of virulence factors papc, afa, sfa/foc, fimh, hly, neuc, ibea, and iucc were 53.3%, 51.7%, 53.3%, 56.7%, 23.3%, 31.7%, 20%, and ...
The present study was done to evaluate the presence of antibiotic resistance genes in Lactococcus garvieae isolated from cultured rainbow trout, West Iran.The isolates were examined for antimicrobial resistance using disc diffusion method. Of the 24 strains tested, 21 were resistant to ampicillin (87.5%), 9 to erythromycin (37.5%) and 19 to tetracycline (79.1%). Fourteen strains were resistant ...
background: poultry and poultry products are among the major sources of salmonella infections for humans. increasing occurrence of antimicrobial resistance among salmonellae has become a serious public health concern. the detection of extended spectrum b-lactamase (esbl) producers among salmonella spp. has increased in recent years. objectives: the purpose of this study was to investigate the a...
results the number of s. pneumoniae isolates resistant to benzylpenicillin, imipenem, oxacillin and ceftazidime were 94.5%, 100%, 100%, and 21.8%, respectively. analysis of mutation in the genes for pbp showed that 85% of isolates had mutations in pbp2x, pbp2b and pbp1a. susceptibility to benzylpenicillin was decreased once the number of mutated pbp genes in s. pneumonia increased. according to...
Background Acinetobacter baumannii is an important agent of nosocomial infections. There are several reports on the presence of disinfectants-resistant Acinetobacter baumannii developed by qacE and qacEΔ1 genes in medical centers. Objective The current study aimed to assess the relevant antimicrobial susceptibility and to determine the frequency of genes encoding resistance to disinfectants i...
BACKGROUND Antimicrobial resistance remains a growing and significant concern in human and veterinary medicine. Current laboratory methods for the detection and surveillance of antimicrobial resistant bacteria are limited in their effectiveness and scope. With the rapidly developing field of whole genome sequencing beginning to be utilised in clinical practice, the ability to interrogate sequen...
BACKGROUND: Poultry and poultry products are among the major sources of Salmonella infections for humans. Increasing occurrence of antimicrobial resistance among Salmonellae has become a serious public health concern. The detection of extended spectrum b-lactamase (ESBL) producers among Salmonella spp. has increased in recent years. OBJECTIVES: The purpose of this study was to investigate the a...
background: in order to select a better antibiotic choice for treatment of pseudomonas aeruginosa infections, this study was conducted to determine the frequency of resistance to some antipseudomonal β-lactams in p. aeruginosa isolates from patients in tehran, iran. in addition, the relation between presence of genes known to be responsible for resistance to β-lactams (ampc, mexc1,2,and mexc3,4...
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...
Introduction: Acinetobacter baumannii is one of the most important nosocomial and community-acquired pathogens that is resistant to many antibiotics. Toxin-antitoxin systems are regulatory systems that maintain bacteria and serve as new targets for Antimicrobial therapies are considered. The prevalence and transcription of these systems in clinical isolates is still unknown. The aim of this stu...
