In order to prove the reason-able and scientificalness of water standards of thallium,the relationships between genotoxicity of thallium andtime on Misgurnus anguillicaudatus peripheral red blood cells are studied.

In order to set found-ations to perfect the water quality indexes and ecological risk assessment,genotoxicity of thallium on Misgurnus anguillicaudatus peripheral red blood cells is studied.

Studies on mechanisms of silver biosorption by Aeromonas SH10;

Multiple resistant genes identified in Aeromonas spp;

Detection of various drug-resistant genes from Aeromonas;

Analysis of Drug Resistance and Detection of Major Virulence Factors of 3 Pathogenic Aeromonas sp. from Fish

Using the method of sensitivity paper disc, the sensitivity of three bacteria (Aeromonas sp.

According to its biochemical behaviours and shapes,Z_(4-2)isone pathogen of this disease that belongs to Aeromonas sp.

Using coding technique,12 species of Vibrio,Aeromonas and Plesiomonas which are common in medicine have been codinged,A7 digit coding identify method has been made up and 208 strains of standard funguses have been determined.

Based on the principles of bacterial taxonomy and Bergey’s manual ofsystematic bacteriology,Identification Keys were established for rapid and simple biochemicalidentification of Vibrto and Aeromonas isolated from the prawn samples.

Analysing more than one hundred phenotypic characters and mol％G+C of the bacterial deoxyribonucleic acids, these isolates were assigned either to motile mesophilic aeromonad in the genus Aeromonas or to Vibrio fluvialis in the genus Vibrio.
