Staphylococcus epidermidis and Staphylococcus aureus are important causative agents of hospital-acquired infections and bacteremia, likely due to their ability to form biofilms. The production of a dense exopolysaccharide (EPS) matrix enclosing the cells slows the penetration of antibiotic down, resulting in therapy failure. The EPS depolymerase (Dpo7) derived from bacteriophage vB_SepiS-phiIPL...

Abstract Background Klebsiella pneumoniae is a common cause of nosocomial infections. Antibiotic resistance and ability to form biofilm, as two key virulence factors K. , are involved in the persistence The purpose this study was investigate correlation between antimicrobial biofilm formation capability among strains isolated from hospitalized patients Iran. Methods Over 10-month period, total ...

Riemerella anatipestifer causes epizootics of infectious disease in poultry that result in serious economic losses to the duck industry. Our previous studies have shown that some strains of R. anatipestifer can form a biofilm, and this may explain the intriguing persistence of R. anatipestifer on duck farms post infection. In this study we used strain CH3, a strong producer of biofilm, to const...

OBJECTIVES To study biofilm production and to detect icaAD, atlE and aap genes in 137 isolates of methicillin-resistant Staphylococcus epidermidis (MRSE) obtained from healthy individuals from the community (35 isolates), from hospitalized patients at the Antônio Pedro University Hospital (25 isolates) and from individuals from a home-care system (HCS; 77 isolates). METHODS Biofilm production...

Background and Aims: Pseudomonas aeruginosa is an opportunistic pathogen. The appearance of the Metallo-β-Lactamases genes and their spread among bacterial pathogens is a matter of concern with regard to the future of antimicrobial therapy.Antimicrobial resistance is an innate feature of bacterial biofilms. Biofilm formation is higher in MDR strains. The present study was undertaken with the ai...

conclusions sphingomonas paucimobilis can cause serious infections, especially in immunocompromised patients with determined risk factors such as indwelling catheters and diabetes mellitus, due to the effects of multiple virulence factors, together with biofilm formation. results all the clinical isolates of s. paucimobilis produced biofilms. primary bacteraemia (n = 16) was the most common cli...

OBJECTIVES We aimed to characterise the staphylococcal cassette chromosome mec (SCCmec) type, genetic relatedness, biofilm formation and composition, icaADBC genes detection, icaD expression, and antibiotic susceptibility of planktonic and biofilm cells of Staphylococcus hominis isolates from blood. METHODS The study included 67 S. hominis blood isolates. Methicillin resistance was evaluated ...

Biofilms are microbial communities characterized by their adhesion to solid surfaces and the production of a matrix of exopolymeric substances, consisting of polysaccharides, proteins, DNA and lipids, which surround the microorganisms lending structural integrity and a unique biochemical profile to the biofilm. Biofilm formation enhances the ability of the producer/s to persist in a given envir...

BACKGROUND Previous studies showed that Staphylococcus aureus and Candida albicans interact synergistically in dual species biofilms resulting in enhanced mortality in animal models. METHODOLOGY/PRINCIPAL FINDINGS The aim of the current study was to test possible candidate molecules which might mediate this synergistic interaction in an in vitro model of mixed biofilms, such as farnesol, tyro...

The objective of this study was to characterize the clonal profile, virulence factors and antimicrobial resistance, particularly oxacillin resistance, of Staphylococcus aureus isolated from sheep milk. Milk samples were collected from all teats for the California Mastitis Test (CMT), somatic cell count, identification of S. aureus, investigation in these strains of genes encoding toxins (sea, s...
