Mell What terminology is used for resident flora?
The microorganisms that usually live on or in a particular body site are called the resident flora (or microbiota).
Which is a characteristic of resident flora?
Resident flora has two main protective functions: microbial antagonism and the competition for nutrients in the ecosystem. In general, resident flora is less likely to be associated with infections, but may cause infections in sterile body cavities, the eyes, or on non-intact skin.
Which one of the following is not the normal flora of the skin?
A major non-human skin flora is Batrachochytrium dendrobatidis, a chytrid and non-hyphal zoosporic fungus that causes chytridiomycosis, an infectious disease thought to be responsible for the decline in amphibian populations.
Is resident flora pathogenic or nonpathogenic?
It comprises bacteria such as Staphylococcus epidermidis, propioni and corynebacteria, which do not have a pathogenic effect on the skin. The microorganisms have important functions: their metabolism inhibits the growth of non-resident bacteria and fungi, and maintain the balance between the colonising microorganisms.
Is resident flora easily removed?
Transient flora are found on the outer layers of skin and are fairly easily removed by handwashing. They are the organisms most likely to result in hospital-acquired infections. The resident flora are more deeply attached to the skin and are harder to remove.
Is resident flora harmless?
Even though most elements of the normal microbial flora inhabiting the human skin, nails, eyes, oropharynx, genitalia, and gastrointestinal tract are harmless in healthy individuals, these organisms frequently cause disease in compromised hosts.
What is another word for normal flora?
The mixture of organisms regularly found at any anatomical site is referred to as the normal flora, except by researchers in the field who prefer the term “indigenous microbiota”.
What is the function of normal flora?
The functions of the normal flora include digestion of substrates, production of vitamins, stimulation of cell maturation, stimulation of the immune system, aid in intestinal transit and colonization resistance.
Is resident flora bad?
Members of the normal flora may cause endogenous disease if they reach a site or tissue where they cannot be restricted or tolerated by the host defenses. Many of the normal flora are potential pathogens, and if they gain access to a compromised tissue from which they can invade, disease may result.
Is normal flora and resident flora the same?
How do residential flora affect human health?
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.
Does resident flora grow inside the epidermis?
Resident microorganisms Resident microbiota are found in the upper parts of the epidermis and congregated in and around the hair follicles. They include: Staphylococcus (see coagulase negative staphylococci)
Which is not the terminology used for resident flora?
C. are caused by microorganisms or their products. D. are caused by vectors. E. involve viruses as the pathogen. Which is not the terminology used for resident flora? E. all of these choices are correct. A. in food. B. the patient’s own normal flora. C. on fomites. D. in the air. E. transmitted from one person to another.
What makes up the flora of a site?
The resident flora at each site includes several different types of microorganisms. Some sites are normally colonized by several hundred different types of microorganisms. Environmental factors, such as diet, antibiotic use, sanitary conditions, air pollution, and hygienic habits, influence what species make up a person’s resident flora.
Can a person get an infection from their resident flora?
However, under certain conditions, microorganisms that are part of a person’s resident flora may cause disease. Such conditions include When antibiotics used to treat an infection kill a large proportion of certain types of bacteria of the resident flora, other resident bacteria or fungi can grow unchecked.
What makes up the transient flora of the body?
The transient flora consists of nonpathogenic or potentially pathogenic microorganisms that inhabit the skin or mucous membranes for hours, days, or weeks; it is derived from the environment, does not produce disease, and
