Haemolysis was determined by cultivation on Blood Agar supplemented with 5% sheep blood …
AK investigated the study. Later, other streptococci having the characteristics of the enterococcus group were transferred to the genus Enterococcus. Enterococci can be found in soil food, water animals and birds. Enterococcus faecalis (E. faecalis) is one of the most common species.
Although they are generally considered to be of low pathogenic potential, it is now well recognized that these organisms can cause serious invasive infections, including endocarditis, bacteremia, urinary tract infection, and pelvic infection [1–5]. AK, RB, and BK provided methodology.
Clonality was established by PFGE and MLST. The reliability of the key has been evaluated with collection type strains and clinical and environmental isolates. 1.

Enterococcus species are gram-positive, facultative anaerobic cocci that are morphologically similar to streptococci on Gram stain . On solid media, Biochemical characters. In view of the fever, blood and, later, urine cultures were taken. Murray, P.R., et al. Further speciation was done on the basis of pigment production, motility test, and biochemical reactions as per standard microbiological guidelines [Antimicrobial susceptibility testing of enterococcal isolates was performed by the disc diffusion technique (DDT) according to Clinical and Laboratory Standards Institute (CLSI) guidelines against penicillin (10 units), ampicillin (10 Minimum inhibitory concentration (MIC) of vancomycin was determined according to the agar dilution method.
Any author submitting a COVID-19 paper should notify us at Nature of specimens recovered from different age groups.Antimicrobial resistance patterns among enterococcal species (N (%)).R3 = resistant to 3 antimicrobial classes, R4 = resistant to 4 antimicrobial classes, R5 = resistant to 5 antimicrobial classes, and MDR = multidrug resistance.B.P. Prevalence of MDR was highest in In the current study, 91 enterococcal isolates were recovered from 5652 clinical specimens within the study period of four months. Further speciation was done on the basis of pigment production, motility test, and biochemical reactions as per standard microbiological guidelines [ 15 , 16 ].
The ratio of male to female in the study participants was 1 : 1. E. raffinosus grew after 24 h on blood agar with 5% sheep blood in smooth, small, grey, non-haemolytic colonies of 1 mm in diameter. During the preceding 4 weeks, she had experienced midthoracic back pain requiring increasing amounts of analgesia but had no difficulty walking and no altered sensation in the legs.
E. faecalis are non-hemolytic on sheep blood agars but are beta-hemolytic on media containing rabbit, horse and human blood. Colonies are small, nonpigmented. While there are 17 or more species of Enterococcus, only two are commonly found in humans: E. faecalis and E. faecium. Enterococci are gram-positive cocci that often occur in pairs (diplococci) or short chains, and are difficult to distinguish from streptococci on physical characteristics alone.
