The Staphylococcus genus includes at least 40 species. Of these, nine have two subspecies, one has three subspecies, and one has four subspecies. Most of the species are harmless and reside normally on the skin and mucous membranes of humans and other organisms. Found worldwide, they are a small component of soil microbial flora.

Staphylococci are typical Gram-positive bacteria forming irregular clusters of cocci. Thus, coagulase is described as a virulence factor( disease-causing factor) of Staphylococcus aureus Staphylococci: cells remain in clusters and divide in multiple planes. Staphylococcus aureus bacteria are cocci shaped bacteria The main criterion for differentiation between Staphylococcus and Streptococcus genera is the catalase test. Staphylococci are catalase positive whereas Streptococci are Catalase negative. Catalase is an enzyme used by bacteria to induce the reaction of reduction of hydrogen peroxide into water and oxygen. The main coagulase-positive staphylococcus is S. aureus, although not all strains of S. aureus are coagulase positive. These bacteria can survive on dry surfaces, increasing the chance of transmission. S. aureus is also implicated in toxic shock syndrome; during the 1980s some tampons allowed the rapid growth of S. aureus, which released toxins that were absorbed into the bloodstream. Any S. aureus infection can cause the scalded skin syndrome, a cutaneous reaction to exotoxin absorbed into the bloodstream. It can also cause a type of septicemia called pyaemia. The infection can be life-threatening. Problematically, MRSA has become a major cause of hospital-acquired infections, and is being, MRSA has also been recognized with increasing frequency in community-acquired infections. The symptoms of a Staph Infection include a collection of pus, such as a boil or furuncle, or abscess. The area is typically tender or painful and may be reddened or swollen.

Coagulase productionEdit

Meaning of coagulase-positive staphylococcus medical term. Coagulase-positive strains produce a variety of toxins and are therefore potentially pathogenic and may cause food poisoning Several different types of CoNS bacteria fall within this category. Often, each bacteria type may cause a different infection. Examples of these types include the following: Coagulase-positive staphylococci include not only Staphylococcus aureus but also S. intermedius and S. hyicus; some strains from each of these species are known to produce enterotoxin S. aureus is coagulase-positive, meaning it produces coagulase. However, while the majority of S. aureus strains are coagulase-positive, some may be atypical in that they do not produce coagulase. S. aureus is catalase-positive (meaning that it can produce the enzyme catalase) and able to convert hydrogen peroxide to water and oxygen, which makes the catalase test useful to distinguish staphylococci from enterococci and streptococci.

Staphylococcus aureus is coagulase positive. Staphylococcus argenteus and the non-human primate-associated Staphylococcus schweitzeri sp. nov are part of the S. aureus complex S. saprophyticus, another coagulase-negative species that is part of the normal vaginal flora, is predominantly implicated in urinary tract infections in sexually active young women. This bacteria species can cause infectious endocarditis. This is a serious infection on the heart valves, which can affect heart function and vessels away from the heart. The infection itself closely resembles endocarditis caused by S. aureus.

  6. Doctors often initially prescribe a very strong antibiotic called vancomycin to treat CoNS infections. They usually give this medication through an IV. Then, based on the antibiotic data, they can choose a better antibiotic.
  7. Growth can also occur in a 6.5% sodium chloride (table salt) solution. On Baird-Parker agar, Staphylococcus species grow fermentatively (without oxygen), except for S. saprophyticus, which grows oxidatively. Staphylococcus species are resistant to bacitracin and susceptible to furazolidone. Further biochemical testing is needed to identify to the species level.

Most of the species are remarkably hardy and can survive dry environments, hot environments and salty conditions that would kill most baceteria and even some viruses. As such, when a patient develops a staph infection, it is usually from bacteria that they have been carrying around for a considerable period of time on their skin, clothing or inside their nose. Several species are a common cause of infections of the skin, blood and stomach of humans. The immune system, in most cases, can easily deal with staph infections. It is easily killed outside the body by antiseptics or even soap and water. However, it can be remarkably opportunistic even in an otherwise healthy individual. It can infect even the smallest puncture or scratch in the skin and, when established, can multiply rapidly. It is a common hospital acquired infection particuarly among the immunocompromised, individuals who have had surgery or people with an intravenous line. Hospital acquired infections are more common than those acquired outside hospitals. Good hygiene practices can effectively reduce the chance of hospital infection. Transmission of staph infections from person to person is a healthy population is rare and it cannot be considered contagious. However, it can spread from an infected person to other patients in a hospital environment through health care workers, visitors or contaminated surfaces (including clothing such as ties and lab coats).

Staphylococcus Albus / Staphylococcus Epidermidis

Doctors often divide staph bacteria into coagulase-positive and coagulase-negative types. Coagulase is an enzyme needed to make blood clot. This enzyme is present in Staphylococcus aureus (S. aureus) bacteria. Doctors typically associate this type with causing more serious infections. Note: All coagulase negative slides must be confirmed using a tube coagulase test as the definitive test for S. aureus. 

1 ways to abbreviate Coagulase-positive Staphylococcus updated 2020. The most popular abbreviation for Coagulase-positive Staphylococcus is: CPS The first S. aureus genomes to be sequenced were those of N315 and Mu50, in 2001. Many more complete S. aureus genomes have been submitted to the public databases, making it one of the most extensively sequenced bacteria. The use of genomic data is now widespread and provides a valuable resource for researchers working with S. aureus. Whole genome technologies, such as sequencing projects and microarrays, have shown an enormous variety of S. aureus strains. Each contains different combinations of surface proteins and different toxins. Relating this information to pathogenic behavior (etiology) is one of the major areas of staphylococcal research. The development of molecular typing methods has enabled the tracking of different strains of S. aureus. This may lead to better control of outbreak strains. A greater understanding of how the staphylococci evolve, especially due to the acquisition of mobile genetic elements encoding resistance and virulence genes is helping to identify new outbreak strains and may even prevent their emergence. Most staph species are named after the source from where they were isolated, although some are named to honor people or places as well. A few are named after their physical characteristics. The taxonomy (species classification) is based on 16s rRNA sequences,and most of the staphylococcal species fall into 11 clusters: Other gram positive cocci include Streptococci and Micrococci Differences between Staphylococci , Micrococci and Streptococci. Character Staphylococci Streptococci Slideshow 618177 by trilby 1.Differentiation between Staphylococcus aureus and other Staphylococci: - COAGULASE test which is positive for Staphylococcus aureus (generally accepted criterion for the identification) and negative for all other Staphylococci. Coagulase is an enzyme used by S.aureus to induce coagulation and convert soluble fibrinogen into fibrin which will protect bacteria from the immune system. It is also a clumping factor for bacterias coalescence. All other staphylococcus species can be collectively referred to as coagulase-negative staphylococci. - STAPHYLOSLIDE test that will determine if bacteria has two types of proteins: Fibrinogen receptor and Protein A. With this test S. aureus will cause notable agglutination. Agglutination will not be seen if the isolate is S. epidermidis or S. saprophyticus. - Presence of HEMOLYSIS. While others dont have any, Staphylococcus aureus has Beta hemolysis. 2.Differentiation between Staphylococcus epidermis and Staphylococcus saprophyticus can be made with reaction to NOVOBIOCIN (antibiotic produced by the actinomycete Streptomyces nivens and used to treat infections by gram-positive bacteria). S. saprophyticus is resistant to novobiocin (at a concentration of 5 mg), and this is used to differentiate the organism from S. epidermidis which is susceptible to novobiocin.

This CoNS bacteria type commonly live on the skin and don’t usually cause infections. A person who has a condition that compromises the immune system, such as lupus, is more likely to experience this infection type. Higher risk is also seen in people who have a foreign body implant, such as: When these bacteria divide, they do so along two axes, so form clumps of bacteria. This is as opposed to streptococci, which divide along one axis, so form chains (strep meaning twisted or pliant). If a person has a CoNS infection, a doctor may perform what’s called a culture. They’ll take a sample of blood, tissue, body fluid, or all of these and send it to a laboratory.

Staphylococcal infections are usually caused by the organism Staphylococcus aureus. S aureus is a gram-positive coccus that is both catalase- and coagulase-positive The widespread incidence of antibiotic resistance across various strains of S. aureus, or across different species of Staphylococcus has been attributed to horizontal gene transfer of genes encoding antibiotic/metal resistance and virulence. A recent study demonstrated the extent of horizontal gene transfer among Staphylococcus to be much greater than previously expected, and encompasses genes with functions beyond antibiotic resistance and virulence, and beyond genes residing within the mobile genetic elements. Both coagulase-negative and coagulase-positive Staphylococcus showed resistance to multiple drugs. Staphylococcus was isolated alone from 48% of cases (out of which coagulase-positive..
