Normal Flora of the Oral Cavity The presence of nutrients, epithelial debris, and secretions makes the mouth a favorable habitat for a great variety of bacteria. Oral bacteria include streptococci, lactobacilli, staphylococci and corynebacteria, with a great number of anaerobes, especially bacteroides.
What is the normal flora of the upper respiratory tract?
The presence of normal upper respiratory tract flora should be expected in sputum culture. Normal respiratory flora include Neisseria catarrhalis, Candida albicans, diphtheroids, alpha-hemolytic streptococci, and some staphylococci.
What does mixed oropharyngeal flora mean?
“Mixed flora” is a commonly returned result yielding not in either indication for therapy or identification of potential causative organisms. We sought to determine whether mixed flora (MF) was in fact a harbinger of impending pneumonia or a benign result that could be therapeutically ignored.
What are the most predominant aerobic organisms in the throat?
Most common aerobic microorganism isolated was S. viridans (47%) among Gram-positive followed by S. aureus (16%).
What is your oropharyngeal?
The oropharynx is the middle part of the pharynx (throat), behind the mouth. The pharynx is a hollow tube about 5 inches long that starts behind the nose and ends where the trachea (windpipe) and esophagus (tube from the throat to the stomach) begin.
