Multiplication of Coagulase-Positive Staphylococci in Grade a Raw Milk Samples

摘要: Abstract Coagulase-positive staphylococci could be recovered from all samples of raw milk examined. The initial counts ranged 25 to 3,300 per milliliter. did not multiply in naturally infected held at 4°C. for seven days. In 10°C. days, these organisms multiply. extent multiplication varied sample and was 1,000-fold the where greatest percentage increase occurred. staphylococcus count obtained 360,000 At 4 holding temperatures, Standard plate increased much more than coagulase-positive staphylococci. Particularly 10°C, usually became unpalatable because microbial activity before population high enough positive concern as a cause food poisoning.
