title: Biochemical characterization of staphylococci isolated from goats.
abstract: Caprine strains of staphylococci show strong and early results in carbohydrate fermentation tests. Their ability to produce DNase and acetoin is weak but they possess a reasonably high degree of phosphatase activity. All the 82 isolates of Staphylococcus aureus isolated from clinically healthy and sick goats produced acid from D-(+)-glucose aerobically at 37 degrees C within 24 h, 98.8% fermented both D-mannitol and maltose, 98.7% fermented sucrose, and 81.7% fermented D-(+)-xylose with acid production, but none fermented L-sorbose. Of the ten coagulase-negative staphylococci characterized to be of animal origin, three produced DNase, but none fermented dulcitol and L-sorbose. All fermented D-(+)-glucose, maltose and D-mannitol, eight fermented D-(+)-xylose and D-sorbitol with acid production. Whilst other coagulase-positive and coagulase-negative staphylococci showed different antibiotic susceptibility patterns, the ten coagulase-negative staphylococci characterized to be of animal origin showed similar antibiotic susceptibility patterns.
