What does growth of normal oropharyngeal flora mean?
That means that when a person has a bacterial respiratory infection, there will typically be harmless bacteria that are normally present in the mouth, throat, etc. ( normal flora) as well as disease-causing (pathogenic) bacteria present.
What is the normal flora in the mouth?
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.
Is E coli a normal flora?
Escherichia coli (E. coli) are very common bacteria in the gastrointestinal tract, and part of the normal bacterial flora. However, some E. coli strains are able to produce a toxin that could produce serious infection.
What are the benefits of flora?
These normal flora provide us with many benefits, which include:
- They prevent colonization by pathogens by competing for attachment & nutrients.
- Some synthesize vitamins that are absorbed as nutrients by the host (e.g. K & B12).
- Some produce substances that inhibit pathogenic species.
Does normal flora cause disease?
Although the normal flora can inhibit pathogens, many of its members can produce disease in humans. Anaerobes in the intestinal tract are the primary agents of intra-abdominal abscesses and peritonitis.
What is the normal flora of the oropharynge?
Normal oropharyngeal flora include anaerobic (eg, Peptostreptococcus) and aerobic species (eg, viridans streptococci). These organisms are rarely pathogenic. 8Staphylococcus, Streptococcus, and Haemophilus species may also be part of the normal oropharyngeal flora,…
What kind of bacteria is in the oropharynx?
The bacteria involved belonged to the patients oropharyngeal flora: S. aureus, Enterobacteriaceae and Pseudomonadaceae. As a result of this study showing the oropharynx to be the source of lower airway colonization/infection, a policy for infection prevention has been outlined.

What is normal bacterial flora?
The normal flora is a bacteria found in or on ones’ bodies on a temporary basis without causing disease. In that respect are larger numbers of bacteria than cells present in ones’ body. The human body contains around 1013 cells, whereas the human physical structure is home to around 1014 bacteria. One-fourth of fecal weight consists of bacteria.
What is normal flora in throat culture?

What is normal flora in the throat?
Normal findings. Normal throat flora include nonhemolytic and alpha-hemolytic streptococci, Neisseria species, staphylococci, diphtheroids, some hemophilus , pneumococci, yeasts, and enteric gram-negative rods.
What is bacterial flora?
Bacterial flora is a community of bacteria that exists on or in the body, and possesses a unique ecological relationship with the host. Bacterial flora encompasses a wide variety microorganisms, and the interactions between microbes and host creates a mutualistic relationship that both entities benefit from.
