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.

Although there was no significant difference in the rate of superinfection and microbiological eradication between participants in the continuous and intermittent groups, the former tended to show more favorable results.
These results were surprising but may result in an opportunity to further our knowledge of the mechanisms involved in resistance to viral superinfection.

The study's authors also said their findings point to a need for post-test counseling for individuals newly diagnosed with HIV infection to emphasize the risk of superinfection and the possible health implications of continuing high-risk behaviors.
The first cases of superinfection were detected because in individual cases something clinical did happen, usually a jump in viral load or drug failure because the second virus was a drug-resistant strain, and for a while such cases were used as a warning to HIV-positive people not to stop using condoms with HIV-positive partners.
Another study in the United States revealed that HIV-positive MSM who believed that superinfection damaged their health were less likely to practise unprotected anal sex than those who did not believe it (16).
Background: HCV infection with concurrent or superinfection with HAV or HBV has the potential to worsen the liver status of HCV-infected individuals.
In severe cases, oral corticosteroids may be needed and, in cases of bacterial superinfection, oral antibiotic therapy may also be necessary.
Organisms may reach the liver either from the biliary tree (ie, secondary to ascending cholangitis), hematogenously, or because of superinfection of necrotic tissue.
This trial used pleasant smelling oils on 30 patients with inoperable squamous cell carcinoma of the head and neck suffering from the offensive smells resulting from superinfection.
On this basis, we have begun small trials of these pleasant smelling oils in patients with inoperable squamous cell carcinoma of the head and neck who also suffer from the offensive smells that result from superinfection with anaerobic bacteria.
Superinfection may occur in as many as 40% of people (particularly those who have multiple partners), and could result in faster progression of the disease since the newly acquired virus may be more dangerous.
