Staphylococcus aureus, also known as "staph," is a type of bacteria that is commonly found on the skin and in the nasal passages of humans. While it is often harmless, it can also cause a range of infections, including skin infections, respiratory infections, and food poisoning. As such, it is important to understand the potential risks associated with staph infections and how to prevent them.

One of the primary reasons why staphylococcus aureus is important is that it can cause a wide range of infections. These infections can range from mild to severe, and can affect various parts of the body, including the skin, respiratory system, and digestive system. Some of the more common types of infections caused by staph include folliculitis (an infection of the hair follicles), abscesses, and impetigo (a contagious skin infection). In rare cases, staph infections can also lead to more serious conditions, such as sepsis (a potentially life-threatening condition that occurs when the body's response to infection damages its own tissues and organs) and toxic shock syndrome (a rare, life-threatening condition that is often associated with tampon use).

Another reason why staphylococcus aureus is important is that it is one of the leading causes of food poisoning. Staph can produce toxins that can contaminate food and cause food poisoning, which is characterized by symptoms such as nausea, vomiting, diarrhea, and abdominal cramps. In severe cases, food poisoning caused by staph can lead to dehydration and other complications.

It is also important to be aware of the potential for staph infections to become antibiotic-resistant. This means that certain strains of staph have developed the ability to survive exposure to antibiotics, which can make them more difficult to treat. Antibiotic-resistant staph infections are more common in healthcare settings, where patients may be more susceptible to infection due to their weakened immune systems.

To prevent staph infections, it is important to practice good hygiene, such as washing your hands frequently and keeping cuts and scrapes clean and covered. It is also important to avoid sharing personal items, such as towels and razors, and to properly cook and handle food to prevent food poisoning. In healthcare settings, it is important for healthcare workers to follow proper infection control protocols, such as wearing gloves and washing their hands, to prevent the spread of staph and other infectious diseases.

In conclusion, staphylococcus aureus is a type of bacteria that can cause a range of infections, including skin infections, respiratory infections, and food poisoning. It is important to be aware of the potential risks associated with staph infections and to take steps to prevent them, such as practicing good hygiene and following infection control protocols in healthcare settings.

Evaluation of an outbreak. It has been proposed that one possible reason for the great deal of heterogeneity within the species could be due to its reliance on heterogeneous infections.

Longitudinal studies of SAB can provide valuable insights into the variability in strain virulence characteristics and changes in strain types over time. Excellent technical aid was furnished by Eleanor Ford, R. Therefore colourless gas bubbles can be observed when H2O2 is added to a colony of Staphylococcus aureus. It is expected that bubbling is observed as a positive result in the catalase test. Moreover, the salty environment along skin surface due to the production of sweat may also account for the abundance of Staphylococcus in humans, since its enzymatic activity is optimal at more alkaline pH 17.

The organism from the clinical specimen from blood culture or pus is then streaked over solid media such as blood agar, tryptic soy agar or heart infusion agar. Gram-negative infections include salmonella, pneumonia, urinary tract infections, and gonorrhea. Difference in structure of Gram positive vs Gram negative bacteria. Find Out How UKEssays. All these macromolecules form complex networks that allow S. In both cases, these give rise to medical implications.

Neonatal infection may be associated with recent or current maternal infection, such as mastitis, cellulitis, abscess, or cesarean wound infection. Växjö, Sweden: European Society of Clinical Microbiology and Infectious Diseases. Morphology The morphology of Staphylococcus can be described as cocci gram positive bacteria arranged in a cluster, which can be readily observed under microscope with the application of gram stain. Vancomycin is the preferred therapy for MRSA infections in neonates. This genus has been chosen for the reason of its abundance on the skin of mammals and the pathogenic nature of one of its member, Staphylococcus aureus.

This ensures that the Staphylococcus isolated can have sufficient time to grow at its optimum temperature. Protein A in various recombinant forms has been used for decades to bind and purify a wide range of antibodies by S. The former acts as a positive control, while the latter acts as a negative control. The Cochrane Database of Systematic Reviews 4 : CD006289. To date, none of these candidates provides protection against a S. The organisms express a plethora of secreted and surface proteins that promote colonization and evasion of immune responses. This enhances the growth of this microbe on skin.

The development of Nabi's StaphVax was stopped in 2005 after phase III trials failed. Despite this, MRSA generally remained an uncommon finding, even in hospital settings, until the 1990s, when the MRSA prevalence in hospitals exploded, and it is now Staphylococcus aureus MRSA is not only a human pathogen causing a variety of infections, such as skin and soft tissue infection SSTI , pneumonia, and sepsis, but it also can cause disease in animals, known as livestock-associated MRSA LA-MRSA. The two protein complex RexAB encoded by S. This genus has been chosen to review because of its abundance on the skin of mammals and the pathogenic nature of one of its member, Staphylococcus aureus. Among carriers, the homologous strain was recovered from the majority of wound colonizations and from all instances of wound sepsis. On the other hand, it is worthwhile to note that Staphylococcus does not have flagella and spores 16. The colonization of Staphylococcus aureus is principally achieved by fibrinogen-binding proteins adhering to the epithelial cells of the humans and thus this may outline a host-parasitic relationship between Staphylococcus and humans 10.

It is expected that bubbling is observed as a positive result with the catalase test. Staphylococcus aureus in the 21st century endures worldwide as a common cause of nosocomial and community bloodstream infections, with high risks of metastatic complications and death. The mechanism of the tests is outlined below. As for oxygen requirement, Staphylococcus is facultative anaerobic 21.
