What is induction of sputum?
What is induction of sputum?
Introduction. Sputum induction is a procedure used for patients who have trouble producing sputum spontaneously. The patient inhales nebulised hypertonic saline solution, which liquefies airway secretions, promotes coughing and allows expectoration of respiratory secretions.
What are gram positive cocci in lungs?
Gram-positive bacteria that can cause pneumonia include the following: Streptococcus pneumoniae: This organism is a facultative anaerobe identified by its chainlike staining pattern. Pneumococcosis is by far the most common cause of typical bacterial pneumonia.
What is gram-positive pneumonia?
Gram-positive pneumonia is a leading cause of morbidity and mortality throughout the world. Of the gram-positive pathogens that cause pneumonia, Streptococcus pneumoniae and Staphylococcus aureus are the most common.
How do you perform a sputum induction?
Sputum induction is conducted by inhalation of nebulised sterile saline solution (isotonic or hypertonic) followed by coughing and expectoration of airway secretions.
How long does sputum induction take?
The full test takes between 30 to 60 minutes. Why do I need this test? Your doctor has requested this test to analyse your sputum for different cells that are found in your lungs. The main cell we look for is the eosinophil.
Is AFB gram positive?
Acid-fast bacteria are gram-positive, but in addition to peptidoglycan, the outer membrane or envelope of the acid-fast cell wall of contains large amounts of glycolipids, especially mycolic acids that in the genus Mycobacterium, make up approximately 60% of the acid-fast cell wall (Figure 2.3C.
Is pneumonia Gram positive or negative?
What is moderate Gram positive cocci?
Gram positive cocci are a group of microorganisms responsible for a variety of infections, including staphylococcal, or staph infections; streptococcal infections, such as strep throat; and pneumococcal infections, such as bacterial pneumonia. Gram positive cocci tend to cause infections only when they invade otherwise sterile or healthy areas.
What are anaerobic Gram positive rods?
Gram negative enteric rods are rod-shaped bacteria that usually are found as single individual cells. This group is facultatively anaerobic, and includes the common enteric bacteria including many pathogens.
What is Gram positive bacillus?
The bacteria that are Gram-positive contain peptidoglycan and techoic acids in their cell walls. These bacteria retain a crystal violet color upon staining. Bacilli and cocci are important forms of Gram-positive bacteria. Some of the examples of Gram-positive cocci are Micrococcus spp., Streptococcus spp., and Staphylococcus spp.
What bacteria are Gram positive cocci in Chains?
Both staphylococci and streptococci are gram-positive cocci, but they are distinguished by two main criteria. Microscopically, staphylococci appear in grapelike clusters, whereas streptococci are in chains. Biochemically, staphylococci produce catalase (i.e., they degrade hydrogen peroxide), whereas streptococci do not.
