Abstract. Fecal indicator bacteria, including total and fecal coliforms, Escherichia coli, and enterococci have been used to indicate the presence of fecal contamination in water used for drinking, shellfishing, and assumptions behind the concept of using fecal indicator bacteria (total coliforms, fecal coliforms, E. coli, and enterococci) are that these Cited by: Evaluation of enterococcal surface protein genes as markers of sewage contamination in tropical recreational waters.

The most widespread systems used to grow biofilms in laboratories are flow cells, drip flow reactors, spinning-disk and tube biofilm reactors. These models have several advantages in common, including growth of biofilms to high population densities, high biomass yields, continuous culture conditions and controlled fluid dynamics.

SUMMARY Human oral bacteria interact with their environment by attaching to surfaces and establishing mixed-species communities. As each bacterial cell attaches, it forms a new surface to which other cells can adhere. Adherence and community development are spatiotemporal; such order requires communication.

Epidemiology of Biofilm-Related Enterococcal Infections. The earliest reports of enterococci in association with infection-related biofilms were probably from the studies that identified Enterococcus faecalis in infected vascular ports from patients (Reed, Moody, Newman, Light, & Costerton, ) and in a urinary stone (Nickel, Reid, Bruce, & Costerton, ).Cited by: 4.

Many hospital-acquired infections (HAIs) are due to biofilms. Characterizing and identifying biofilm infections are the first steps toward their eradication.
This will enable novel strategies to be devised aimed toward the management and control of biofilms. The main nosocomial infections caused by biofilms are bacteremia, urinary tract infections (UTI), and by: ENTEROCOCCI AND THE GENUS ENTEROCOCCUS.
Previously classified in the genus Streptococcus, the enterococci were proposed to be a division comprised of bacteria that generally grow at temperatures of between 10°C and 45°C in % NaCl at pH and to survive at 60°C for 30 min (66, 68,).This classification scheme, proposed previously by Cited by: This chapter reviews many commonly used organisms, experimental approaches, and techniques used for the growth and study of biofilms.
Here, the authors focus on commonly used approaches with a greater emphasis on currently used techniques. They have summarized several diverse techniques for growing and evaluating biofilms below. These include examples of biofilm Cited by: Microb Ecol 44 49 Nayak, B.S., Levine, A.D., Cardoso, A.

Even in single species biofilms, the bacterial population is heterogeneous with respect to growth states, which cover the spectrum from rapidly growing to metabolically inactive. Bacteria in nongrowing zones of a biofilm are uniquely well positioned to survive antimicrobial challenge and are less susceptible than a biofilm in which all of the Cited by: 2.
Horizontal gene transfer (HGT) is an important means to obtain and maintain plasticity of microbial genomes. Basically, bacteria apply three different modes to horizontally exchange genetic material: (1) conjugative transfer mediated by mobile genetic elements (MGE), (2) DNA uptake via transformation, and (3) by: 5.
Bacterial biofilms are intrinsically resistant to antimicrobial treatment, which contributes to microbial persistence in clinical infections. Enterococcus faecalis is an opportunistic pathogen that readily forms biofilms and is the most prevalent enterococcal species identified in healthcare-associated infections.

The influence of microorganisms growing as sessile communities in a large number of human infections has been extensively studied and recognized for 30–40 years, therefore warranting intense scientific and medical research.
