    Bacteria called group A streptococcus (GAS) causes common infections such as strep throat and skin infections. GAS produces a toxic enzyme known as streptolysin O. Your immune system produces antibodies to fight this toxic enzyme. One of these antibodies is called antistreptolysin O (ASO).

    An antistreptolysin O titer measures how much ASO is in your blood. The ASO antibodies start increasing about a week after you experience a strep infection.

    Species of Streptococcus are classified based on their hemolytic properties. Hemolysis refers to the ability of the bacteria to break down red blood cells.

    Species of Streptococcus are classified based on their hemolytic properties. Hemolysis refers to the ability of the bacteria to break down red blood cells. There are three types of hemolysis: alpha, beta, and gamma. Alpha-hemolytic species cause oxidization of iron in hemoglobin molecules within red blood cells, giving it a greenish color on blood agar. Beta-hemolytic species cause complete rupture of red blood cells. Gamma-hemolytic species do not cause hemolysis at all.

    Streptococcus is a genus of gram-positive coccus or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. In the medical setting, the most important groups are the alpha-hemolytic streptococci S. pneumoniae and Streptococcus viridans group, and the beta-hemolytic streptococci of Lancefield groups A and B (also known as “group A strep” and “group B strep”).

    Streptococci infections are divided into several groups: Group A streptococcus, Group B streptococcus, Group C streptococcus, and Group G streptococcus. Group A strep, sometimes called GAS, tends to affect the throat and the skin. People may carry GAS in these areas yet not show any symptoms of illness. Most group A strep infections cause relatively mild illness, but on rare occasions, these bacteria can lead to severe and even life-threatening diseases.

    Staphylococcus is a genus of Gram-positive bacteria in the family Staphylococcaceae from the order Bacillales. Under the microscope, they appear spherical, and form in grape-like clusters. Staphylococcus species are facultative anaerobic organisms.

    The genus Staphylococcus consists of Gram-positive, non-spore-forming cocci that are often found as normal human microbiota of the skin and nasal cavity.

    The genus Staphylococcus consists of Gram-positive, non-spore-forming cocci that are often found as normal human microbiota of the skin and nasal cavity. There are five organisms to consider as potential human pathogens in this genus:
    1. S. aureus
    2. S. epidermidis
    3. S. saprophiticus
    4. S. haemolyticus, and
    5. S. hominis.

    The major test reaction to use in Staphylococcus identification is the coagulase test reaction, which divides the genus Staphylococcus into 2 groups:
    1. Coagulase-negative species, and
    2. Coagulase-positive species.
    The test media that you will run for identification depends on which category your organism falls in.

    1. Microscopic morphology:
    S. aureus cells are Gram-positive and appear in a spherical shape. They are often in clusters resembling a bunch of grapes when observed under a light microscope after Gram staining. The name ‘Staphylococcus’ was derived from Greek, meaning a bunch of grapes (staphyle) and berry (kokkos). The scanning electron microscopic observation reveals roughly spherical-shaped cells with smooth surfaces. The diameter of the cells ranges from 0.5 to 1.0 μM. The transmission electron microscopy of cells shows a thick cell wall, distinctive cytoplasmic membrane, and amorphous cytoplasm.

    2. General cultural and biochemical characteristics:
    S. aureus is an aerobic and facultative anaerobic organism that forms fairly large yellow or white colonies on nutrient-rich agar media. The yellow colour of the colonies is imparted by carotenoids produced by the organism. The term ‘aureus’ is derived from Latin, which refers to the colour of gold. The organism is often haemolytic in blood agar due to the production of four types of haemolysins (alpha, beta, gamma, and delta). Nearly all isolates of S. aureus produce coagulase enzyme, a virulence factor that also helps in the identification of the organism. The organism is salt tolerant and is able to grow in a mannitol-salt agar medium containing 7.5% sodium chloride. The organism is catalase-positive and oxidase negative.

    Medical laboratory diagnosis:
    The primary objective in laboratory diagnosis is to identify whether the diagnosed S. aureus isolate is methicillin-resistant. Since MRSA emerged as a problematic pathogen, a systematic diagnostic approach is necessary for early diagnosis so that treatment with appropriate antibiotics can be initiated as early as possible. For species identification, slide and tube coagulase tests, latex agglutination tests, and PCR-based tests are used. For detection of MRSA, determination of minimum inhibitory concentration (MIC) of methicillin or oxacillin or cefoxitin using broth micro-dilution method, cefoxitin disk screen, oxacillin agar screen and latex agglutination test for PBP2a and molecular methods for detection of mecA are employed.

    6. Skin infections,
    7. Pneumonia,
    8. Endocarditis, and
    9. Osteomyelitis.

    Symptoms of a staph infection vary depending on the location and severity of the infection. For example, a localized staph infection may cause a collection of pus, such as a boil or abscess. The area may be tender or painful and may be reddened and swollen.
