sulfur (S)

[sul′fər]

Etymology: L

a nonmetallic, polyvalent, tasteless, odorless chemical element that occurs abundantly in yellow crystalline form or in masses, especially in volcanic areas. Its atomic number is 16, and its atomic mass is 32.07. It is used in the production of sulfuric acid and used in metallurgy, rubber vulcanization, petroleum refining, and many other industrial processes. Sulfur has been used in the treatment of gout, rheumatism, and bronchitis and as a mild laxative. The sulfonamides, or sulfa drugs, are used in the treatment of various bacterial infections. Also spelled sulphur.

sulfur

a chemical element, atomic number 16, atomic weight 32.064, symbol S. See Table 6. Elemental sulfur is fed to animals to reduce their volume of feed intake, for example in a feedlot using self-feeders. It is also fed as an oldfashioned worm prophylaxis and coccidiostat.

Overfeeding of elemental sulfur causes enteritis characterized by black, evil smelling diarrhea. See also hydrogen sulfide poisoning.

sulfur dioxide

a poisonous gas liberated by some industrial enterprises, e.g. copper smelting, from silage to which sodium metabisulfite has been added as a preservative and in oldfashioned treatments for mange. The gas causes irritation of the upper respiratory tract and pneumonia in severe cases. Commonly used as a meat preservative where it selectively destroys thiamin and has been incriminated as a cause of thiamin deficiency, particularly in dogs and cats.

sulfur granule

small, soft to mineralized bodies in the pus of lesions of actinomycosis. Called also drusen.

lime-sulfur

see lime-sulfur.

sulfur myopathy

skeletal and myocardial degeneration caused by the feeding of toxic levels of sulfur.

sulfur nutritional deficiency

ruminants may need supplemental inorganic sulfur if the bulk of their nitrogen is not in the form of protein but as urea or ammonium phosphate. A deficiency in these circumstances causes anorexia, weight loss, poor digestion and fall in milk yield.

precipitated sulfur

a scabicide, antiparasitic, antifungal and keratolytic. Called also milk of sulfur.

sulfur stinker

a can of preserved meat contaminated by Clostridium nigrificans causing the formation of hydrogen sulfide, and black or purple staining of the inside of the can.

sulfur sublimatum, sublimed sulfur

a parasiticide and scabicide. Called also flowers of sulfur.

technetium coated sulfur colloid

used in scintigraphy of the liver and reticuloendothelial systems. Called also ^99mTc sulfur colloid.
