A VIRUS family that causes INFECTION of mucous membrane tissues throughout the body. Adenoviruses are responsible for a wide range of illness including upper respiratory infection, viral CONJUNCTIVITIS, GASTROENTERITIS, and URINARY TRACT INFECTION (UTI). These infections primarily affect children age 10 and younger. Infection with one adenovirus confers immunity to that strain of virus; vulnerability to infection with other strains of adenovirus remains.
A parasitic INFECTION of the gastrointestinal tract. The PARASITE responsible is Entamoeba histolytica, a single-cell organism (an ameba) that enters the body by drinking water or eating food that contains E. histolytica in cyst form. The cyst is a protective encasing within which the ameba may sustain itself in a dormant stage for weeks to months outside a host (organism that provides NUTRIENTS for a parasite). Once within the SMALL INTESTINE the cyst
Antibiotic medications - Drugs that kill BACTERIA and certain other microorganisms. Antibiotic medications are the mainstay of treatment for bacterial INFECTION. Broad-spectrum antibiotics are capable of killing numerous types of bacteria; narrowspectrum antibiotics kill specific types or strains of bacteria. There are seven primary classifications of antibiotic medications-aminoglycosides, cephalosporins, macrolides, quinolones (fluorquinolones),
Drugs that kill fungi (yeast). Antifungal medications are available for topical or systemic treatment. Some fungal infections require both. Antifungal medications work through various mechanisms to interfere with the ability of fungi to survive or reproduce. Broadspectrum antifungal medications are effective for treating a variety of fungal infections; narrow-spectrum antifungals are effective in treating specific fungal infections. Topical preparations
Antiviral medications - medications to shorten the course and lessen the severity of illness due to viral INFECTION as well as reduce viral shedding to minimize contagiousness. Some antiviral medications are able to prevent viral infection from developing after exposure to the VIRUS. Antiviral medications mark a fine line because they must destroy viruses without damaging the cells that host them. Most antiviral medications accomplish such a task by
An illness that results from INFECTION with the parasitic protozoan Babesia microti. Most people who have babesiosis do not have symptoms; the infection causes illness primarily in people who are IMMUNOCOMPROMISED or who have had SPLENECTOMY (surgical removal of the SPLEEN). The bite of the Ixodes tick, found in the northeastern United States, is the mode of transmission. Babesiosis is rare in other parts of the United States.
What is bacteria and definition of bacteria Bacteria - single-cell microorganisms (microbes). Bacteria are the most ancient and primitive life forms known, with fossils dating back more than 3 billion years. A bacterium’s structure is very simple, consisting of a rigid cell wall that supports and contains the cytoplasm, fragments of RNA, and a single strand of DNA within a nonencapsulated (unbordered) nucleus. Though bacteria are capable of
What is Campylobacteriosis and Campylobacter jejuni An illness that results from INFECTION with the bacterium Campylobacter jejuni. The BACTERIA are commonly present in domestic birds such as chickens and turkeys without causing illness in the birds; the typical source of infection in people is undercooked poultry (especially chicken) or cross-contamination that occurs from improper handling and preparation of poultry. Health experts estimate that half
