Haemagglutinin And Chitinase Activities Of Virulent Aeromonas Hydrophila Islolated From Cyprinus Carpio

Abstract

 In the present study the Hemeagglutination and Chitinolytic activity of extracellular products (ECP) secreted from Aeromonas hydrophila were examined. The present study showed infectivity experiments, incomplete creation of extracellular products and chitinase activity of the A. hydrophila. In haemagglutination assay in the present experiment, bacterial agglutination takes place in 1:1, 1:2, 1:4, 1:8,1:16,1:32 dilutions in the E.S-2 treated O blood groups and in 1:1,1:4 where as the ES -1and ES-3 failed to agglutinate. Generally, whole cells showed a wider range of enzymic activities than ECP. The results showed that extra cellular product chitin could be a promising source for pathogenic factor in microorganisms.
