Peptone salt agar

We studied the microbiological quality and prevalence of Vibrio parahaemolyticus in finfish and shellfish sold in the domestic markets of West Bengal, India following enrichment in alkaline peptone water and further plating on to thiosulfate citrate bile salt sucrose agar.

Aglaonema, also called Chinese evergreen, is a popular and low-maintenance houseplant, which not only beautifies our home but also promotes healthier lives by cleaning pollutants from the air. Taking into consideration all these points, the demand for ornamental plants is increasing gradually.

In this study systematic bacteriological examination of aseptically collected 150 shrimp samples, 27 samples of hand swabs from fish handlers were collected from retail fish outlets, and 23 stool samples from patients suffered with digestive disturbances after consumption of seafood reported to private clinics, all from Navsari city were investigated. The samples were enriched in Alkaline Peptone Water followed by direct plating on selective media viz. Thiosulfate Citrate Bile Salt Sucrose agar and Vibrio parahaemolyticus sucrose agar.

 In the present work we have extended these experiments by the use of the plate count in an effort to throw more light on the mechbanism of the salt action. Since our previous experiments have shown that the salt effect is magnified on the acid side of the region of optimum growth (Sherman and Holm, 1922), we have used in the present work media adjusted to a reaction of pH 5.4. All of the counts here reported represent the average of triplicate plates on extract-pepton agar incubated for three days at 33°C. Further details of the experiments are given in the appendix.
