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 ...

anti-adhesion therapy represents a potentially promising avenue for the treatment and prevention of tuberculosis in a post-antibiotic era. adhesins are surface-exposed microbial structures or molecules that enable pathogenic organisms to adhere to host surfaces, a fundamental step towards host infection. although several mycobacterium tuberculosis adhesins have been identified, it is predicted ...

background and objectives: this study was designed to evaluate the activity of quercus infectoria galls extract (qifge) on virulence factor production and inhibition of quorum sensing (qs) in pseudomonas aeruginosa. materials and methods: minimum inhibitory concentration (mic) of qifge against 5 strains of p. aeruginosa was determined. the extract at sub-mic was used to determine biofilm format...

materials and methods fifty mrsa isolates were collected from 200 clinical samples from three different educational hospitals in ahvaz, iran, and identified by biochemical tests including catalase, oxidase, tube coagulase, mannitol fermentation, and sensitivity to furazolidone, resistance to bacitracin, pyr test and voges-proskauer test. their resistance to methicillin was evaluated using the d...

background and objectives: brucella, causative of brucellosis, has some potential virulence factors involved in brucella replication and its strategies to circumvent the immune response. one of them is the virb gene that encodes the type іv secretion system proteins (t4ss) involved in intracellular replication of organism. brucella virulence factor a ( bvf a), and urease ( ure ) has also been d...

Pasteurella multocida possesses various virulence factors, including capsule, lipopolysaccharide, fimbriae, toxins, outer membrane proteins, and adhesions. Adhesins have a crucial role in mediating colonization and invasion of the host. The aim of the present study was to identify the prevalence of adhesion factor genes and resistance/sensitivity patterns among the avian P. multocida isolates f...
