Staphylococcus Pyogenes

Human beings are hosts for many bacterial species that colonize our skin as their natural flora. The skin acts as a superior barrier and first line of defense against bacterial infections. When they do occur, these infections are mild and easily treatable; however some can become very serious and even life-threatening. Staphylococcus aureus and Streptococcus pyogenes are uncommon bacteria, but they are responsible for a wide variety of bacterial pyodermas [1]. In some cases, the host for bacterial infections can become contagious to others. In this paper, 40 patients were presented with a visible skin infection, and all have similar manifestations of symptoms. These patients do not seem to be responding to the current antimicrobial therapy. …show more content…

They can cause diseases from direct contact (infection) or production of toxins by the bacteria. Examples of a Staphylococcus disease are boils, impetigo, food poisoning, cellulitis, and toxic shock syndrome [2]. MRSA is a form of bacterial infection that is resistant to many antibiotics including methicillin, amoxicillin, penicillin, and oxacillin, which makes it challenging to treat this infection [3]. When patients are suspected of a bacterial infection, the primary step would be to see if they have been in the same area. If they have, have they shared any personal items or attended activities or been to places that involved in crowding, skin-to-skin contact, and shared equipments or supplies. This might include athletes, students and staff in the school, military personnel, and people who recently received inpatient hospital care [4]. Although the information was not given in a great detail, some common skin infections can be eliminated because of the fact that they did not respond to microbial therapy and type of symptoms. One of the examples is the recent discovery of Propionibacterium acnes. In the studies, there are "good" and "bad" strains of the bacteria. The bacteria can aggravate an immune response which causes redness, swollen bumps to develop on the skin (acne), or pus. Acnes have been treated the same over the past few decades, raising the concerns for long-term antibiotic use that cause bacterial resistance …show more content…

The sample of the organism is to isolate visible colonies in pure culture (e.g. on agar plates). The identification is based on taxonomic principles applied to the clinical microbiological situation. These classical methods for speciation of bacteria are based on morphological and metabolic characteristics. Susceptibility testing of isolates (i.e. establishing the minimal inhibitory concentration or MIC) can help in selection of antibiotics for therapy [6]. Additionally, molecular methodology (for characterization of specific genes or gene segments) is now common
