    Pneumococcal pneumonia is caused by the bacterium Streptococcus pneumoniae. Laboratory diagnosis of pneumococcal pneumonia can be done through several methods, including blood tests, chest X-rays, pulse oximetry, sputum test, and urine test. Blood tests can confirm an infection and try to identify the type of organism causing the infection. A chest X-ray can help diagnose pneumonia and determine the extent and location of the infection. Pulse oximetry measures the oxygen level in your blood. A sputum test can confirm the cause of infection. A urine test can identify bacterial infection of Streptococcus pneumoniae.

    Pneumococcal pneumonia is caused by the bacterium Streptococcus pneumoniae. This bacterium can cause contagious and potentially severe illness, including pneumonia, meningitis, and sepsis, so early diagnosis and treatment is important. Pneumococcal disease can affect many different systems in your body. It may result in conditions with mild symptoms like a sinus infection (sinusitis). But it can also lead to pneumonia, blood infection (sepsis), or bacterial meningitis — and may be life-threatening at any age.

    Dr Md shahriar kabir B H M S; MPH Enlightened dr.basuriwala

    Streptococcus pyogenes is a species of Gram-positive, aerotolerant bacteria in the genus Streptococcus. These bacteria are extracellular and made up of non-motile and non-sporing cocci (round cells) that tend to link in chains. They are clinically important for humans, as they are an infrequent, butRead more

    Streptococcus pyogenes is a species of Gram-positive, aerotolerant bacteria in the genus Streptococcus. These bacteria are extracellular and made up of non-motile and non-sporing cocci (round cells) that tend to link in chains. They are clinically important for humans, as they are an infrequent, but usually pathogenic, part of the skin microbiota that can cause Group A streptococcal infection. S. pyogenes can cause a variety of diseases such as streptococcal:
    1. Pharyngitis,
    2. Rheumatic fever,
    3. Rheumatic heart disease, and
    4. Scarlet fever.

    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. 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.
