Effects and Diseases of the Bacterium Streptococcus Pyogenes The bacteria Streptococcus pyogenes has been infecting people for more than a century. Once a deadly bacterium‚ now only an antibiotic from curing the diseases it causes. Streptococcus pyogenes has been responsible for excruciating throat pains and even in some cases a horrendous rash included. This paper will talk about the history of this organism‚ how it acts as a pathogen‚ how people attract it‚ the symptoms that come with the disease

Gram Positive Enterics: 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

IDENTIFYING GRAM POSITIVE COCCI As mentioned in Exercise 8‚ “Identifying Gram Negative Rods”‚ identifying bacteria is a common activity in the microbiology lab. Like the game Clue™‚ each time you gather a piece of information to solve the mystery‚ you gather some information that supports some identities and eliminates others from contention. In the lab‚ the process continues as you gather more information until only one microbe remains and all others have been eliminated as possibilities. Thus

My unknown turned out to be gram positive bacteria cocci shaped with long chain cell arrangement. The unknown was gram positive because the cells stained blue-violet ‚this indicate that my unknown has ability to retain crystal violet-iodine after alcohol application on the cells which is a gram
