INFLUENCES OF VARIOUS FACTORS ON BACTERIAL COUNT RECOVERED FROM MOIST TISSUE BACTERIAL CARRIER

In order to study the influences of various factors on bacterial count recovered from moist tissue bacterial carrier,living bacterial count method was used to observe experimentally the factors such as the time of bacterial contamination of the moist tissue,degree of driness of bacterial carrier and slant culture condition.Results: With prolonging the shelving time of the bacterial carrier,the bacterial count recovered tended to decrease. The bacterial count recovered from completely dried bacterial carrier was significantly lower than the initial bacterial count.The bacterial count recovered from the bacterial carrier prepared from the slant culture of Staphylococcus aureus after shelving at 4℃ for 18～24 h was significantly different from that recovered from the bacterial carrier prepared from the culture without shelving.Conclusion: The factors such as shelving time of bacterial carrier,degree of driness of bacterial carrier and storing of fresh slant culture at 4℃ can influence the recovery of bacteria from bacterial carrier.
