| infection, urinary tract | An infection in the urinary system that begins when microorganisms cling to the opening of the urethra (the canal from the bladder) and begin to multiply. most utis are due to one type of bacteria, e. (escherichia) coli, a normal denisen of the colon. An infection in the urethra leads to inflammation called urethritis. From there bacteria may move up, causing a bladder infection (cystitis) and if the infection is not treated promptly, bacteria may go up the ureters to infect the kidneys (pyelonephritis). Factors leading to uti include any abnormality of the urinary tract (such as a urinary tract malformation or a kidney stone) that obstructs the flow of urine, an enlarged prostate gland that slows the flow of urine, catheters (tubes) in the bladder, diabetes (due to changes of the immune system), and any disorder that suppresses the immune system. Women have more uti than men, probably because a woman's urethra is shorter (allowing bacteria quick access to the bladder) and nearer sources of bacteria from the anus and vagina. For many women, sexual intercourse seems to trigger an infection, as may the use of a diaphragm. Not everyone with a uti has symptoms but symptoms commonly include a frequent urge to urinate and a painful, burning when urinating (dysuria). The urine may look milky or cloudy, even reddish if blood is present. Kidney infection can cause pain in the back or side below the ribs. In children, symptoms may be easily missed or misunderstood. A child with a uti may be irritable, not eat normally, have an unexplained fever, have incontinence or loose bowels, or just not thrive. (12 Dec 1998) |
|---|---|
| terminal infection | An acute infection, commonly pneumonic or septic, occurring toward the end of any disease and often the cause of death. Synonym: agonal infection. (05 Mar 2000) |
| endogenous infection | Infection caused by an infectious agent already present in the body, the previous infection having been inapparent. (05 Mar 2000) |
| endosymbiotic infection | A situation where a cell that has been infected by a virus is prevented from dividing but is not immediately killed. (09 Oct 1997) |
| yeast infection | <gastroenterology, microbiology, oncology> Infection with a fungus of the genus Candida. It is usually a superficial infection of the moist cutaneous areas of the body and is generally caused by Candida albicans, it most commonly involves the skin (dermatocandidiasis), oral mucous membranes (oral candidiasis), respiratory tract (bronchocandidiasis) and vagina (vaginal candidiasis or thrush). Rarely there is a systemic infection or endocarditis. Oral candidiasis: describes a fungal (yeast) infection of the oral cavity due to Candida. It is common in infants, diabetics or those on chemotherapy and is well recognised in patients with HIV infection and AIDS. Oesophageal candidiasis: Infection of the oesophagus by the yeast-like fungus Candidal albicans. Usually occurs in the immunocompromised individual (AIDS or following chemotherapy). Oral candidiasis is a predisposing factor but oesophageal involvement can occur without evidence of infection in the oral cavity. Symptoms include difficulty swallowing, pain on swallowing and oral lesions. Diagnosis is made using endoscopy. Treatment is with antifungal agents such as ketoconazole or fluconazole. Synonym: moniliasis, candidosis, oidiomycosis, blastodendriosis. (16 Dec 1997) |
| zoonotic infection | An infection shared in nature by man with other species of vertebrate animals. (05 Mar 2000) |
| urinary tract infection | A bacterial infection of the urethra, bladder, ureters or kidneys (part of the urinary tract). Common symptoms of a urinary tract infection include pain with urination, urinary urgency and increased frequency of urination. Acronym: UTI (15 Nov 1997) |
| fish tapeworm infection | An infection caused by the fish tapeworm, Diphyllobothrium latum, one of the giant tapeworm species. Humans may get infected after eating undercooked fish that contain tapeworm larvae. Fish tapeworms are more common in cold, fresh water lakes such as the Great Lakes area. The adult worm grows in the intestine to lengths up to 30 feet. Segments of the worm and blood may occasionally be passed in the stools. Infection can also lead to vitamin B12 deficiency. Diagnosis is via microscopic examination of the stools. Treatment is with single dose niclosamide. (27 Sep 1997) |
| laboratory infection | Accidentally acquired infection in laboratory workers. (12 Dec 1998) |
| focal infection | An old term which distinguishes local infection's (focal) from generalised infection's (sepsis). (05 Mar 2000) |
| focal infection, dental | Secondary or systemic infections due to dissemination throughout the body of microorganisms whose primary focus of infection lies in the periodontal tissues. (12 Dec 1998) |
| food infection | Microbial infection resulting from ingestion of contaminated food. (09 Oct 1997) |
| force of infection | <epidemiology> The per capita rate at which susceptibles are infected. (05 Dec 1998) |
| latent infection | An asymptomatic infection capable of manifesting symptoms under particular circumstances or if activated. (05 Mar 2000) |
| fungal infection | 1. (groin) Tinea cruris is a fungal infection of the perineum, better known as jock itch. This condition is often treated with clotrimazole or miconazole cream. Good general hygiene is vital in the prevention of tinea cruris. Keep the groin area clean and dry and avoid chafing. Launder athletic supporters frequently. Use an antifungal or drying powder after showering. 2. (nail) A fungal infection that involves the fingernails. Nails generally split, flake and grow too thick. 3. (scalp): A fungal scalp infection also known as tinea capitis. A crusting and scaly lesion of the scalp that can also be associated with localised hair loss. Treatment requires oral (systemic) antifungal medications. (05 Jan 1998) |
