THRUSH


Meaning of THRUSH in English

also called Oral Candidiasis, Mycotic Stomatitis, or White Mouth, fungus infection characterized by raised white patches on the tongue that resemble milk curds. When gently scraped off, these patches reveal inflamed tissue that tends to bleed easily. Beginning on the tongue, the creamy white spots can spread to the gums, palate, tonsils, throat, and elsewhere. The causative organism, the yeastlike fungus Candida albicans, is ubiquitous and needs only favourable conditions in the mouth and a weakened host to flourish. Although most common among infants, thrush sometimes occurs in the elderly, immune-suppressed patients, or others in whom the normal balance of microorganisms in the mouth has been upset. The spread of the infection in the oral cavity usually produces only slight symptoms of fever and gastrointestinal irritation, however. Thrush is generally cured by the antibiotics nystatin or clotrimazole taken as mouthwashes. any of about 300 members of the songbird family Turdidae, treated by many modern authorities as a subfamily of the Old World insect eaters, family Muscicapidae. The thrushes are sometimes divided into two groups, the chat-thrushes (subfamily Saxicolinae) and the true, or typical, thrushes (Turdinae). Thrushes are widely considered closely related to the Old World warblers (Sylviidae) and flycatchers (Muscicapidae), with which they intergrade through several genera. Generally, thrushes are slender-billed songbirds with the tarsus (lower leg) booted; i.e., covered in front with a single long scale instead of many short ones. The young are usually spotted in the first plumage, and there is a single annual molt. The chat-thrushes, e.g., the western bluebird (Sialia mexicanus), are generally smaller, with slenderer legs, thinner bill with fewer bristles at its base, and more colourful plumage (see chat-thrush). Thrushes vary from 13 to 30 centimetres (5 to 12 inches) in length. They are usually not brightly coloured; but many have patches of bright yellow, red, or blue on otherwise plain plumage. Thrushes occur virtually worldwide but are most diverse in the Old World, especially in Africa. The northern species are strong migrants. Occupying a wide range of arboreal and terrestrial habitats, thrushes eat insects and fruit; a few take snails or earthworms. They build open cup-shaped nests (or, in the case of a few of the chat-thrushes, occupy cavities), in which they lay three to six pale, often bluish eggs. Representative true thrushes are species of the genus Turdus, which include the blackbird, fieldfare, ouzel, and redwing of Europe, as well as the American robin. Other true thrush groups are called ground thrush and nightingale thrush. A number of unrelated birds are called thrushes by reason of resemblance to turdids, including the antthrush (see antbird); babbling thrush (see babbler); jay thrush and Chinese thrush (see laughing thrush); jewelthrush (see pitta); and wrenthrush (q.v.).
