What is the difference between an endogenous disease and an exogenous disease?

There are three basic patterns of infection in the ICU: primary endogenous, secondary endogenous, and exogenous. In exogenous infection, no microbial carriage precedes colonization and infection. In endogenous infection, infection is preceded by oropharyngeal or GI carriage.

What is endogenous infection?

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.

Is gonorrhea endogenous or exogenous?

Bacteria that are part of normal internal ecosystems, also known as bacterial flora, are called Endogenous Bacteria. A significant amount of prominent diseases are induced by exogenous bacteria such as gonorrhea, meningitis, tetanus, and syphilis.

Are endogenous infections of internal organs considered nosocomial?

Our data show that the subset of patients with overgrowth on admission is at risk of primary endogenous infection of internal organs. Finally, some decisions voice a more general reluctance to qualify endogenous infections as nosocomial.

What are some examples of Exogenous infections?

These are the typical bacteria and viruses that we get from hospitals and from other infected persons in our community. Pneumonia, measles, herpes, and chickenpox maybe some of the things we can consider as exogenous infections.

What is the pathophysiology of extracellular infectious agents?

Extracellular infectious agents live outside the cell; these include species of Streptococcus and Haemophilus. These microorganisms have a carbohydrate capsule that acts as an antigen to stimulate the production of antibody, an essential component of humoral immunity. Infection may be transmitted by direct contact, indirect contact, or vectors.
