Bacteria that cause pus are called pyogenic. Although pus is normally of a whitish-yellow hue, changes in the color can be observed under certain circumstances. Pus is sometimes green because of the presence of myeloperoxidase, an intensely green antibacterial protein produced by some types of white blood cells.
Chestnut Mare. Chestnut Mare is a song by the American rock band The Byrds, written by Roger McGuinn and Jacques Levy during 1969 for a planned country rock musical named Gene Tryp. The musical was never staged and the song was instead released in September 1970 as part of The Byrds' (Untitled) album.
In Thoroughbred horse racing, a mare is defined as a female horse more than four years old. The word can also be used for other female equine animals, particularly mules and zebras, but a female donkey is usually called a jenny. A broodmare is a mare used for breeding. A horse's female parent is known as its dam. An uncastrated adult male horse is called a stallion and a castrated male is a gelding. Occasionally, the term horse is used to designate only a male horse.
