Streptococcus faecalis Streptococcus faecalis also known as strep D‚ is now known as Enterococcus faecalis. Enterococcus faecalis is part of the Enterococcaceae family. This organism is a gram positive and usually occurs in pairs called diplococci. It is facultative anaerobic‚ and is nonmotile. This organism is a lactose fermenter and can be grown in 6.5% NaCL. Enterococcus faecalis is considered non-hemolytic‚ meaning it does not break down blood cells. Enterococcus faecalis is part of normal

Enterococcus By Richard Guilford Enterococcus Enterococcus‚ or more appropriately enterococci‚ are a family of bacteria in the division firmicutes (meaning strong skin and referring to the cell wall) and the class bacilli (which refers to its rod like shape). They look just like streptococcus bacteria from physical characteristics alone. In fact‚ members of the genus Enterococcus were classified as Group D Streptococcus until 1984 when genomic DNA analysis showed that a separate genus classification

Enterococcus faecalis is a gram positive‚ commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals [1].E. faecalis can cause life-threatening infections in humans. Moreover‚ the antibiotic resistance exhibited at high levels by E. faecalis contributes to its pathogenicity [2]. Several reports state that enterococcal species possess the property of causing a variety of diseases in humans [3‚ 4]. It is known from previous studies that Enterococcus faecalis can cause endocarditis

CHAPTER I INTRODUCTION 1. ENTEROCOCCUS FAECALIS AND STAPHYLOCOCCUS AUREUS OUTLINE The Human indigenous micro flora consists of opportunistic pathogens along with other nonpathogenic bacterial strains. Two eloquent members of the category of gram- positive bacteria‚ Enterococcus faecalis and Staphylococcus aureus belong to this category. Being a facultative anaerobe‚ aero tolerant anaerobe respectively‚ both of these organisms inhabited the human body for centuries. Ability to thrive in extreme condition

Antibacterial activity of allopathic medicine versus phytomedicine against Enterococcus faecalis: An in-vitro study. Abstract Background: A successful endodontic treatment depends on appropriate instrumentation‚ irrigation‚ decontamination and obturation. Decontamination of root canal plays a crucial role in the success of endodontic treatment. Therefore‚ a suitable medicament is essential which can effectively eliminate bacterial contamination. Aim and objectives: To investigate and compare the

Enterococcus Faecalis Sensitivity Towards Ampicillin‚ Penicillin‚ and Tetracycline Introduction Enterococci are bacteria that are included in the intestinal flora of humans and are relatively harmless. One method Enterococci maintain a symbiotic relationship is by hydrolyzing esculin in the presence of bile (Susan L. Fraser‚ 2012). However Enterococci are in the top three-nosocomial infections. When infected‚ enterococci can cause numerous infections such as urinary tract infection coupled with

Antibacterial action of the irrigants against Enterococcus faecalis in the root canal The overall percentage reduction of E. faecalis inside the root canal after biomechanical procedures was presented in table1. All the irrigants significantly reduced bacteria in comparison with positive control group (P< 0.01). The average reduction of bacteria in the presence of E.galbie did not have any significant difference with 2.5% NaOCl‚ CHX 2%‚ CHX 0.2% and M.communis L. (P > 0.05). The average reduction

Vancomycin-resistant enterococci are enterococcus strains‚ such as Staphylococcus faecalis‚ now called Enterococcus faecalis that are resistant to the antibiotic vancomycin. Enterococci infections are the most common type acquired by hospitalised patients. Vancomycin was the last-line antibiotic for hospital treatment of serious

In the experiment involving varying pH levels‚ E. faecalis‚ S. epidermidis‚ L. lactis‚ and L. casei were subjected to different pH levels and then were allowed to incubate in order to determine the minimum‚ maximum‚ and optimum pH levels for growth of specific bacterial species. It was found that lower pH levels between 2 and 4 inhibited or promoted little to no growth for E. faecalis‚ S. epidermidis‚ and L. casei. It is evident that these bacteria were resistant to alkaline environments‚ however
