| screw worm infection | Infection with larvae of the blow fly cochliomyia hominivorax (callitroga americanum), a common cause of disease in livestock in the southern and southwestern u.s.a. (12 Dec 1998) |
|---|---|
| secondary infection | An infection, usually septic, occurring in a person or animal already suffering from an infection of another nature. (05 Mar 2000) |
| puerperal infection | An infection occurring in the puerperium or postpartum period. (12 Dec 1998) |
| self-infection | 1. Reinfection by microbes or parasitic organisms on or within the body that have already passed through an infective cycle, such as a succession of boils, or a new infective cycle with production of a new generation of larvae and adults, as by the nematode Strongyloides stercoralis or the cestode Hymenolepsis nana. 2. Self-infection by direct contagion as with parasite eggs passed in the infectious state transmitted by fingernails (anal-oral route), as with the pinworm, Enterobius vermicularis. Synonym: autoreinfection, self-infection. (05 Mar 2000) |
| pyogenic infection | Infection characterised by severe local inflammation, usually with pus formation, generally caused by one of the pyogenic bacteria. (05 Mar 2000) |
| nail infection, fungal | The most common fungus infection of the nails is onychomycosis. Onychomycosis makes the nails look white and opaque, thickened, and brittle. Older women (perhaps because oestrogen deficiency may increase the risk of infection). And men and women with diabetes or disease of the small blood vessels (peripheral vacscular disease) are at increased risk. Artificial nails (acrylic or wraps ) increase the risk because when an artificial nail is applied, the nail surface is usually abraded with an emery board damaging it, emery boards can carry infection, and. Water can collect under the nail creating a moist, warm environment for fungal growth. Alternative names include tinea unguium and ringworm of the nails. (12 Dec 1998) |
| natural focus of infection | An ecosystem in which an infectious agent normally persists in nature; e.g., yellow fever virus in a jungle monkey-Haemagogus mosquito ecosystem. (05 Mar 2000) |
| subclinical infection | <epidemiology> An infection in which symptoms are sufficiently mild or inapparent to escape diagnosis other than by positive confirmation of the ability to transmit the infection or serologically. (05 Dec 1998) |
| nosocomial infection | <microbiology> Hospital acquired infection: commonest are due to Staphylococcus aureus, Pseudomonas aeruginosa, E. Coli, Klebsiella pneumoniae, Serratia marcescens and Proteus mirabilis. (18 Nov 1997) |
| surgical wound infection | Infection occurring at the site of a surgical incision. (12 Dec 1998) |
| disseminated gonococcal infection | Infection from Neisseria gonorrhoea which is spread to distant parts of the body beyond the original portal of entry (usually the lower genital tract). Usually manifest by rash and arthritis. (05 Mar 2000) |
| droplet infection | Infection acquired through the inhalation of droplets or aerosols of saliva or sputum containing virus or other microorganisms expelled by another person during sneezing, coughing, laughing, or talking. (05 Mar 2000) |
| inapparent infection | Presence of infection in a host without the occurrence of recognizable symptoms or signs. (05 Mar 2000) |
| infection | 1. <microbiology> Invasion and multiplication of microorganisms in body tissues, which may be clinically unapparent or result in local cellular injury due to competitive metabolism, toxins, intracellular replication or antigen antibody response. The infection may remain localised, subclinical and temporary if the bodys defensive mechanisms are effective. A local infection may persist and spread by extension to become an acute, subacute or chronic clinical infection or disease state. A local infection may also become systemic when the microorganisms gain access to the lymphatic or vascular system. 2. An infectious disease. (18 Nov 1997) |
| infection calculus | A calculus associated with infection and/or obstruction, usually composed of struvite (magnesium ammonium phosphate). Synonym: infection calculus. (05 Mar 2000) |
