Streptococcus iniae biofilm formation enhances environmental persistence and resistance to antimicrobials and disinfectants

Streptococcus pyogenes Survival of Streptococcus pneumoniae and Biofilm Formation Enhances Fomite

Biofilm Formation, Antimicrobial Resistance and Biofilm-Related Genes among Uropathogens Isolated from Catheterized Uro-Oncology Patients

Background and Objective: Despite the critical importance of catheter as an indwelling medical device, its prolonged utilization in hospitalized patients may lead to infection. This study aimed to identify distribution of uropathogenic bacteria isolated from catheterized uro-oncology patients, their biofilm production, and antimicrobial resistance patterns to generally -used antibiotics. Mater...

antibiotic resistance and biofilm formation of enterococcus faecalis in patient and environmental samples

conclusions the results of the antibiotic resistance and other data suggest that there is a possible common clone of e. faecalis, which could rapidly disseminate in patients and the environment. results the results indicated that, 86% of patient and 29% of environmental isolates carried ebp genes. the ability of the isolates to strongly attach was 62% and 71% for patient and environmental sampl...

Biofilm formation in Streptococcus pneumoniae

Biofilm-grown bacteria are refractory to antimicrobial agents and show an increased capacity to evade the host immune system. In recent years, studies have begun on biofilm formation by Streptococcus pneumoniae, an important human pathogen, using a variety of in vitro model systems. The bacterial cells in these biofilms are held together by an extracellular matrix composed of DNA, proteins and,...

Increased Zinc Availability Enhances Initial Aggregation and Biofilm Formation of Streptococcus pneumoniae

Bacteria growing within biofilms are protected from antibiotics and the immune system. Within these structures, horizontal transfer of genes encoding virulence factors, and promoting antibiotic resistance occurs, making biofilms an extremely important aspect of pneumococcal colonization and persistence. Identifying environmental cues that contribute to the formation of biofilms is critical to u...
