Staph infections are caused by a staphylococcus bacterium‚ Staphylococcus aureus. S. aureus is a purple‚ cocci shaped cell with its morphological arrangements in grape-like clusters‚ it is determined by a bacteriological stain‚ known as the Gram stain. This determines it to be a gram positive bacterium. When grown on bacteriological media‚ S. aureus appears as a large white to golden colony. It is not very fastidious but it grows well‚ either aerobically or under anaerobic conditions and produces

Staphylococcus aureus (S. aureus) is a gram positive bacterium that when looked at under a microscope it appears to be a cluster of what looks like purple circles. This shape is known as cocci. When grown on a TSA plate‚ Staphylococcus aureus appears to be yellow to opaque in color. S. aureus is known as one of the most resistant bacterium to multiple antibiotics and considered the most pathogenic. Everyone is susceptible to S. aureus with one way of transmission being from foods such as chicken

The problems that arise regarding the antibiotic resistance of certain bacteria has continue to worry the health industries. One of these bacteria is the Staphylococcus aureus. It has been one of the major causes of hospital-acquired infections which has resulted to a lot of deaths each year. Description Staphylococcus aureus is a gram-positive bacteria which indicates that it has a cell wall structure with a thick layer of peptidoglycan. It is a facultative anaerobe which allows it to perform

Methicillin Resistant Staphylococcus Aureus Staphylococcus aureus bacteria‚ commonly known as staph‚ are very common. It is "a spherical gram-positive parasitic bacterium of the genus Staphylococcus‚ usually occurring in grapelike clusters and causing boils‚ septicemia‚ and other infections." In fact‚ many people have some living on their skin all of the time and it can cause infection anywhere in the body. There are antibiotics that have been known to kill this bacterium. Unfortunately

Staphylococcus Aureus (Staph Aureus) is a gram-positive coccal bacterium and is a member of the Firmicutes phylum. It is most commonly found in the respiratory tract or in skin infections and can sometimes occur from food poisoning. This bacterium is very common and can be found in almost all parts of the world. Every year around 500‚000 people in the USA go to the hospital to get treated (National Institutes of Health‚ 1999). Staph Aureus has genetically developed to resist many antibiotics (Larsen

The Staphylococcus aureus‚ a bacteria that is found in the nose‚ has been a leading cause of infection in hospitals around the world. This is an antibiotic-resistant‚ nosocomial pathogen‚ meaning that it’s acquired at hospitals. To test the idea that these infections have increased‚ eight hospitals participated in a study within the New York Area. The following are hospitals participated in this study: VA hospital‚ Kings County Hospital‚ Columbia University Medical Center‚ New York-Presbyterian Queens
