It causes the hydrolysis of a beta-lactam (as penicillin to penicilloic acid); found in most strains of staphylococcus bacteria that are naturally resistant to penicillin.

pointer (sh)




Dog breed, of hound, spaniel, and setter ancestry, first recorded งใ 1650 in Great Britain and named for the dog's rigid posture in the direction of quarry.

Pointers were originally used to point out hares and were later trained as bird dogs. The pointer stands 23-28 in. (58-71 cm) tall and weighs 50-75 lb (23-34 kg); it has a long muzzle, hanging ears, tapered tail, and a short, smooth coat, usually white with dark markings. The German short-haired pointer, another sporting breed, tracks, points, and retrieves; it is about the size of a pointer and has a short coat of solid liver colour or liver and gray-white.
