What microorganisms could be found in the upper respiratory tract?
The upper respiratory tract microbiome of infants Moraxella, Staphylococcus, Streptococcus, Haemophilus, Dolosigranulum, and Corynebacterium are the six most common genera, of which one or two usually dominate the nares and nasopharyngeal microbiome of infants [11, 90, 91].
Does the lower respiratory tract have normal flora?
The upper respiratory tract is colonized by an extensive and diverse normal microbiota, many of which are potential pathogens. Few microbial inhabitants have been found in the lower respiratory tract, and these may be transients.
What is the normal flora of the throat?
Normal results would include finding organisms that grow in healthy throat tissues (normal flora). These organisms include non-hemolytic and alpha-hemolytic streptococci, some Neisseria species, staphylococci, diphtheria and hemophilus organisms, pneumococci, yeasts, and Gram-negative rods.
What does normal respiratory 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 normal flora is found on the skin?
Enterobacter, Klebsiella, Escherichia coli, and Proteus spp. are the predominant Gram-negative organisms found on the skin. Acinetobacter spp also occurs on the skin of normal individuals and, like other Gram-negative bacteria, is more common in the moist intertriginous areas.
What bacteria are commonly found in the mouth?
Some bacteria like Streptococcus, Granulicatella, Gemella, and Veillonella are amongst the predominant microorganisms of the oral cavity; however, the majority of bacteria are explicit to certain sites.
What does many normal respiratory flora mean?
What is normal flora and why is it important?
The normal flora prevent colonization by pathogens by competing for attachment sites or for essential nutrients. This is thought to be their most important beneficial effect, which has been demonstrated in the oral cavity, the intestine, the skin, and the vaginal epithelium.
What is a bacterial respiratory infection?
A bacterial respiratory tract infection is an infection of the sinuses, throat, airway, or lungs. Bacterial infections may develop after having a viral illness like a cold or the flu. Symptoms tend to localize to one particular area.
What are normal flora How do normal flora affect human health?
