A second infection which affects the treatment of the first infection, because it is resistant to the drug used to treat the first.
Infection occurring during treatment with antimicrobials for another infection; it usually is caused by a change in the normal microscopic inhabitants of tissue (e.g., a vaginal yeast infection occurring during antibiotic treatment for a bacterial infection); secondary infection caused by an opportunistic pathogen (e.g., fungus- caused pneumonia occurring in a person debilitated or immunosuppressed because of another illness or treatment).
Growth of certain harmful organisms normally kept in check by other organisms that are temporarily destroyed by an antibiotic medication.
A second infection that occurs in addition to a previous infection. Superinfections are often caused by a different microbial agent than the one that caused the first infection. This new infectious agent may have originated from a source outside the body or from within the body. If the initial infection was treated with antibiotics, the microorganism causing the superinfection may be resistant to the treatment used.
An infection arising during the course of another infection and caused by a different microorganism, which is usually resistant to the drugs used to treat the primary infection. The infective agent may be a normally harmless inhabitant of the body that becomes pathogenic when other harmless types are removed by the drugs or it may be a resistant variety of the primary infective agent.
A new infection caused by an organism different from that which caused the initial infection. The microbe responsible is usually resistant to the treatment given for the initial infection.
The occurrence of a subsequent viral infection following the establishment of a previous infection caused by a distinct virus.
A secondary infection that emerges while an ongoing infection is still present. Typically, this term denotes an infection caused by a microorganism that has developed resistance to the drugs employed against the initial infection. An instance of this is candidiasis (thrush) arising due to the use of antibiotic medications. These antibiotics eradicate the body’s usual flora (microorganisms naturally present in the body without causing harm), which usually regulate the growth of candida yeast, preventing its excessive multiplication.
A secondary or subsequent infection caused by the same microorganism, as observed in conditions such as tuberculosis, for example.
