STAPHYLOCOCCUS AUREUS SEM
Methicillin-resistant golden staph (Staphylococcus aureus) (MRSA), scanning electron micrograph (colorized SEM, x 9560, the line represents two microns). These bacteria are gram-positive cocci and facultative anaerobes that typically gather in clusters, as we see it here. Golden staph is responsible for food poisoning, cutaneous infections, pneumonia, toxic shock syndrome, ... The MRSA is one of the most frequent multiresistant bacterial strains in healthcare facilities (hospital-acquired infections). Golden staph (Staphylococcus aureus) > Staphylococcus > Staphylococcaceae > Bacillales > Firmicutes > Bacterium. This 2005 scanning electron micrograph (SEM) depicted numerous clumps of methicillin-resistant Staphylococcus aureus bacteria, commonly referred to by the acronym, MRSA; Magnified 9560x. Recently recognized outbreaks, or clusters of MRSA in community settings have been associated with strains that have some unique microbiologic and genetic properties, compared with the traditional hospital-based MRSA strains, which suggests some biologic properties, , virulence factors like toxins, may allow the community strains to spread more easily, or cause more skin disease. A common strain named USA300-0114 has caused many such outbreaks in the United States. Methicillin-resistant Staphylococcus aureus infections, , bloodstream, pneumonia, bone infections, occur most frequently among persons in hospitals and healthcare facilities, including nursing homes, and dialysis centers. Those who acquire a MRSA infection usually have a weakened immune system, however, the manifestation of MRSA infections that are acquired by otherwise healthy individuals, who have not been recently hospitalized, or had a medical procedure such as dialysis, or surgery, first began to emerged in the mid- to late-1990's. These infections in the community are usually manifested as minor skin infections such as pimples and boils. Transmission of MRSA has been reported most frequently in
