superinfection

 [soo″per-in-fek´shun]
a new infection occurring in a patient having a preexisting infection; for example, bacterial infection may occur in patients with viral respiratory disease, or a chronic hepatitis B carrier may become infected with hepatitis D virus. Superinfection can complicate the course of antimicrobial therapy when the organisms causing the new infection are resistant to the drugs being used to treat the first infection.

su·per·in·fec·tion

(sū'pĕr-in-fek'shŭn),
A new infection in addition to one already present.

superinfection

/su·per·in·fec·tion/ (-in-fek´shun) a new infection occurring in a patient having a preexisting infection, such as bacterial superinfection in viral respiratory disease or infection of a chronic hepatitis B carrier with hepatitis D virus.

superinfection

(so͞o′pər-ĭn-fĕk′shən)
n.
1. The act or process of superinfecting a cell or organism.
2. An infection following a previous infection, especially when caused by microorganisms that have become resistant to the antibiotics used earlier.

superinfection

[-infek′shən]
Etymology: L, super + inficere, to stain
an infection occurring during antimicrobial treatment for another infection. It is usually a result of change in the normal tissue flora favoring replication of some organisms by diminishing the vitality and then the number of competing organisms, as yeast microbes flourish during penicillin therapy prescribed to cure a bacterial infection.

superinfection

Infectious disease An infection that follows a prior infection, which occurs when native regional flora are substantially reduced, often by antibiotics, allowing invasion by opportunistic organisms, as in pseudomembranous colitis or esophageal candidiasis

su·per·in·fec·tion

(sū'pĕr-in-fek'shŭn)
A new infection in addition to one already present.

superinfection

A second infection, often with a fungus or virus, complicating an existing infection. The superinfecting organism is usually one which is resistant to the drugs being used in the treatment of the original infection.

superinfection

an infection added to one already present.

Superinfection

A condition in which a patient with a contagious disease acquires a second infection, as when a patient with granuloma inguinale is also infected with syphilis.

superinfection

secondary infection, i.e. in addition to an existing infection

su·per·in·fec·tion

(sū'pĕr-in-fek'shŭn)
A new infection in addition to one already present.

superinfection,

n an infection occurring during antimicrobial treatment for another infection.

superinfection

a new infection complicating the course of antimicrobial therapy of an existing infection, due to proliferation of bacteria or fungi resistant to the drug(s) in use.
