Macroscopic Examination: Stools resembles "rice water", contains mucus, epithelial cells, and large number of Vibrios. Microscopic Examination: Dark field Microscopic examination of stool sample shows rapidly motile Vibrio bacteria. Cultural Characters: Enrichment is done in Alkaline Peptone water at pH 8.7 for 6-8 hours incubation. Typical yellow color colonies appear in Thiosulfate-Citrate-Bile salts-Sucrose (TCBS) agar after 18 hours incubation. Organisms can be confirmed from culture by staining and examining under microscope. Specific Tests: Vibrio cholerae are further identified by slide agglutination tests using anti-O group 1 antiserum and by biochemical reactions. |

Posted on: 11/18/2008 In Zimbabwe the National Water Authority is failing to supply water to large parts of the urban areas. This has resulted in residences drawing on Boerhole Water and others purchasing from borehole owners. My question is what is the risk of being infected by the Cholera Bacteria especially in schools who use the water to wash with but not to drink? |
