Study Of Enterotoxigenicity Of B. Cereus Emetic Strain By Skin Vasopermeability Reaction In Rabbits And Poultry
The present study pertains to the toxigenicity of lessThan i greaterThan Bacillus cereus lessThan /i greaterThan emetic strain isolated from raw milk and milk products in Kashmir valley. The study was conducted during October 2009 lessThan b greaterThan - lessThan /b greaterThan June 2010. A total No. of 175 samples comprising of 50 raw milk and 125 of different milk products were tested. lessThan i greaterThan Bacillus cereus lessThan /i greaterThan emetic strains were isolated from 8 of the raw milk and 20 of the milk product samples, (6, 5, 4, 3 and 2 samples out of 25 each of rasgulla, burfi, ice-cream, rasmalai and cheese/paneer, respectively). lessThan i greaterThan B. cereus lessThan /i greaterThan emetic strains were isolated from 16 percent of the raw milk. Among the different milk products analysed lessThan i greaterThan B. cereus lessThan /i greaterThan emetic strains could be isolated from 20, 24, 12, 16 and 8 percent of burfi, rasgulla, rasmalai, ice-cream and cheese/paneer, respectively. The field isolates and the standard strain of lessThan i greaterThan Bacillus cereus lessThan /i greaterThan had similar cultural, morphological and biochemical characteristics. Raw milk, burfi and ice-cream revealed biotypes 2, 5 and 7, whereas, rasmalai and cheese/paneer revealed only biotype 5. Biotypes 2 and 5 were recovered from rasgulla. lessThan i greaterThan Bacillus cereus lessThan /i greaterThan emetic enterotoxin (BCEET) produced by field isolates and the standard strain produced comparable vascular permeability reaction on intradermal inoculation. The development of moderate to severe VPR was observed in rabbit skin, where as there was mild VPR in poultry skin.
