Staphylococcus, Enterococcus and Streptococcus is considered as a leading cause of many diseases.

Methicillin Staphylococcus aureus is defined as strains of bacteria that are resistant to beta-lactam agents, including the synthetic penicillins (eg, methicillin, oxacillin) and the cephalosporins. MRSA can resist the effects of many common antibiotics, so it is difficult to treat. If the infection spreads to the blood stream and becomes systemic may increases risk for life threatening complications. First sign of MRSA are small red bumps that resemble pimples, boils or spider bites. Next they may mature into deep and painful abscesses that require surgical draining. If the bacteria is not confined to the skin and infect the blood stream, causing potentially fatal infections in bones, joints, surgical wounds, the bloodstream, heart valves and lungs.

Methicillin-resistant Staphylococcus aureus, or MRSA, is a bacterium that is resistant to many available high- level beta-lactam antibiotics, which include penicillins, “antistaphylococcal” penicillins and cephalosporins. Staphyloccoci are the most important bacteria that cause disease in humans. MRSA is sometimes branded as a nosocomial infection as it usually plagues patients that are receiving treatment in a hospital. The skin is the most common site of infection, where MRSA can cause cellulitis, folliculitis, or boils in the skin, but can also commonly be found in the nose, underarm, groin, upper respiratory tract, intestine, vagina and rectal areas of the body. MRSA infections occur with there is a break in the skin that allows the Methicillin resistant

MRSA (Methicillin Resistant Staphylococcus Aureus) is one of the most recent superbugs to become a health problem. MRSA is a species of Staphylococcus Aureus that is resistant to the antibiotic methicillin and antibiotics like it. Doctors are struggling to find proper treatment because of its resistance to the beta-lactam ring, the core of most antibiotics. The most lethal strain is the CC398 strain, most commonly found on livestock. There are approximately 80,000 invasive MRSA infections and 11,000 deaths every year. (CNN.com)

Staphylococcus aureus is a cluster bacterium that can be found on the skin of around 25% of healthy adults. This bacterium is growing everyday all over the world and many people have no idea they are even carriers. “Staphylococcus aureus is present in the nose of adults (temporarily in 60% and permanently in 20 to 30%) and sometimes on the skin” (Levison). This bacterium has the ability to cause skin infection and sometimes may lead to severe life threatening diseases. There are several different strains of staphylococcus and depending on the severity of the infection is how a health care provider decides the treatment most efficient. Impetigo is more common in children, but adults still have the chance of getting this skin condition. Toxic Shock Syndrome is also associated with S. aureus and is found in at least 50% of the cases to date. S. aureus can display a variety of symptoms and all vary with the disease at hand. Symptoms can range from a boil on the skin or in the nose to skin rashes. More severe symptoms can be carbuncles and infection of the blood (sepsis).Staphylococcus aureus is an ugly bacterium; that can lead to several diseases, such as Toxic Shock Syndrome and Impetigo. S. aureus has multiple symptoms and is treated with a variety of antibiotics.

HA-MRSA which is healing center procured mrsa that spreads through restorative offices. HA-MRSA spreads through direct contact with human services experts who convey the ailment or things like swathes or covers that are contaminated with mrsa disease. A patient with a clinic gained disease is around seven times more inclined to bite the dust than a uninfected patient. The following mrsa is CA-MRSA which is group gained mrsa, this can spread anyplace outside of the human services world. CA-MRSA will in all probability spread because of sterile conditions that are awful. The vast majority regularly confuse this contamination for skin break out, pimples, bug chomps, or rashes. Another mrsa is a Urinary Tract Infection which is a MRSA that causes torment and weight in the lower stomach area or pelvic locale. The forward sort is Pulmonary MRSA, Pulmonary MRSA can be created from intubation of a man amid the time they stay at a healing center overnight or even from only a visit. Aspiratory mrsa sometimes has been being contracted in the group. It tends to present itself as pneumonia ( a respiratory condition there is contamination of the lung ) however can exacerbate rapidly and cause other life debilitating conditions, for example, sepsis. The last mrsa will be MRSA in Blood, or Sepsis which is a medicinal condition where the blood gets to be tainted or defiled by microbes. This can make the contaminated

Staph infection comes in different types and may cause disease due to direct infection or production of toxins by the bacteria. Boils, impetigo, food poisoning, cellulitis, and toxic shock syndrome are all examples of diseases that can be caused by Staphylococcus [2]. MRSA is a form of bacterial infection that is resistant to numerous antibiotics including methicillin, amoxicillin, penicillin and oxacillin, thus making it challenging to treat the infection [3].

Problem: An unknown bacteria in test tube #13 needs to be identified out of the list of bacteria provided as possible. Hypothesis: If different tests were carried out to identify the bacteria’s characteristics, then the bacteria could be identified, because a dichotomous key can be used to eliminate all other bacteria in the list Procedure: 1. Obtain an inoculating loop, Bunsen burner, test tube #13 and a test tube rack. 2.

Before the turn of the 21st century, physicians across the country were realizing that the possibility of being able to treat and cure virtually any microbial infection with the use of a single or a combination of antimicrobial medications was becoming more and more of a challenge. In the late 1960s and early 1970s, reports of pathogenic resistance to even the most potent antimicrobial medications of the time were being sent to the Centers for Disease Control. Among even the most dangerous pathogens that have developed and are developing drug resistance to one or many antimicrobials, Staphylococcus aureus (S. aureus) is perhaps a case in which the world is most familiar and of the greatest concern within the medical community due to its natural virulence-its ability to cause a multitude of life-threatening infections, and its above average ability to combat and adapt to a vast array of environmental conditions.

CA-MRSA is more prevalent in healthy children and younger adults without healthcare exposure. It has microbiologic and genetic properties similar to health care-associated MRSA, thus enabling these bacteria to spread much more easily, and cause more skin infections. (2) It is also able to penetrate intact skin, thus reaching the deeper tissues, making it the predominant bacterium for skin and soft tissue infections in both outpatient and emergency department patients.

The most pervasive anti-toxin safe disease that must be considered and comprehend in the current world is the "Methicillin-safe Staphylococcus aureus (MRSA) contamination". It is caused by a strain of Staphylococcus microbes that have created impervious to the basic anti-microbial for treating ordinary staphylococcic aureus disease. This anti-microbial safe contamination happened in patients living in doctor's facilities. The MRSA disease in the healing centers is caused by utilizing obtrusive gadgets or strategies, for example, intravenous tubing and surgeries.

Methicillin-resistant Staphylococcus Aureus also known as MRSA a bacterial staph infection. MRSA causes skin infections that can be painful, swollen and very contagious. There are two types of MRSA, Community-acquired MRSA (CA - MRSA) and Healthcare-associated MRSA (HA-MRSA).

Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that causes infections in different parts of the body. It is tougher to treat than to prevent from most strains of S. aureus because of its resistant to some commonly used antibiotics. Arguments on

The release of two exotoxins from certain strains of S. aureus can lead to Staphylococcal scaled skin syndrome (SSSS), which is characterized by blistering skin. Invasion into the body can lead to more serious health problems including pneumonia (a frequent complication of influenza), mastitis, phlebitis (inflammation of the veins), meningitis, and urinary tract infections. If the bacterium is allowed to colonize even deeper tissues more serious conditions such as osteomyelitis and endocarditis may result. The most serious consequences of these deeper tissue infections occur when the bacterium invades the bloodstream leading to septic shock and possibly death.

Gram positive cocci are responsible for the most infections in humans. According to Lindahl, Carlehalm and Areschoug, “During the last three decades, S. agalactiae has also emerged as an important cause of human disease and is now the most common cause of life-threatening invasive bacterial infections (septicemia,
