Many illnesses are associated with an alteration of the immune system
homeostasis
due to a combination of factors, including exogenous bacterial insult, endogenous breakdown (e.g. development of a disease that results in immuno suppression), or an exogenous hit like surgery that simultaneously alters immune ...
What is an example of endogenous infection?
Disease can occur when microbes included in normal bacteria flora enter a sterile area of the body such as the brain or muscle. This is considered an endogenous infection. A prime example of this is when the
residential bacterium E. coli of the GI tract enters the urinary tract
.
What are endogenous infections?
Endogenous infections are
caused by an overgrowth of organisms that are normally present in the genital tract
. One example of an endogenous infection is bacterial vaginosis. Iatrogenic infections may be introduced into the reproductive tract by medical procedures.
What is exogenous infection?
Exogenous Infections | exo- “
outside”
; -genous “born from”
Exogenous infections, in contrast, involve a pathogen entering a patient’s body from their environment. These pathogens can be introduced through a contaminated device, healthcare worker, surface, or other vector.
What is endogenous and exogenous sources?
The primary exogenous sources of energy for GIT bacteria are undigested carbohydrates and proteins provided via the host diet. Endogenous energy sources include
mucin, bile acids, digestive enzymes, and epithelial cells
.
Is an endogenous infection?
n.
An infection caused by an infectious agent that is already present in the body
, but has previously been inapparent or dormant.
How can endogenous infections be prevented?
To prevent endogenous infection,
selective gastrointestinal decontamination (SD) that requires bacteriological surveillance of the patient’s intestinal microflora and the environment
, as well as the use of eubiotics.
What are 3 common examples of nosocomial infections?
Some of the common nosocomial infections are
urinary tract infections
, respiratory pneumonia, surgical site wound infections, bacteremia, gastrointestinal and skin infections.
Which source is a vehicle for infection transmission?
Common vehicle transmission: Common vehicle transmission refers to transmission through
a contaminated source
. Examples include food, medication, intravenous fluid, or equipment that transmits infection to multiple hosts. This transmission may result in a large-scale outbreak.
What does exogenous mean in medical terms?
Exogenous:
Originating from outside the organism
.
What are exogenous causes?
When you’re identifying causes of disease,
toxins in your environment
would be exogenous causes (they come from outside you), while genetic predisposition (something inside you) would be considered an endogenous cause.
Which infectious oral disease is exogenous?
By definition,
dental caries
is an infectious and transmissible disease because it is caused by bacteria colonizing the tooth surfaces. Unlike most infectious diseases affecting humans, caries is the result of an imbalance of the indigenous oral biota rather than a nonindigenous, exogenous pathogen.
Which microorganism is associated with exogenous infection?
The infection can be caused by the normal flora of the skin but may also be caused by exogenous bacteria, most commonly,
group A Streptococcus or Staphylococcus
.
What is a endogenous source?
Endogenous sources include
errors of metabolism that lead to large accumulations of elements
such as copper or iron, which are normally only found in trace quantities.
What are exogenous agents?
An exogenous factor is
any material that is present and active in an individual organism or living cell but that originated outside that organism
, as opposed to an endogenous factor. Exogenous factors in medicine include both pathogens and therapeutics.
What is endogenous protein?
The human gut endogenous proteins (GEP) include
mucins
, serum albumin, digestive enzymes, hormones, and proteins from sloughed off epithelial cells and gut microbiota, and numerous other secreted proteins.
