ABSTRACT
To explore the possibility to type the Brucella strains isolated in Guangdong province with analytical method to detect the fatty acid components and to collect the basic data of fatty acid components of Brucella strains, 29 strains of Brucella were selected for analysis on the bacterial fatty acid components and the cluster analysis on the collected data was performed with Sherlock analysis soft-ware (MIDI). It was demonstrated that the main fatty acid components of Brucella strains isolated in Guangdong province were 19∶0 cycloω8c acid, 16∶0 acid and 18∶0 acid. The content of 19∶0cycloω8c acid was highest in B.abortus, followed by B.melitensis and lowest in B.suis.-In addition, the content differences of 19∶0cycloω8c and 18∶0 acid between B. melitensis and Brucella suis were statistically significant; and that of 19∶0cycloω8c and 18∶0 acid between strains isolated in 1965 and those isolated in recent 3 years was statistically significant. It was also shown that the fatty acid components of Brucella strains were stable, but the contents of fatty acid components were different in different species.-It is evident that at certain euclidean distance, 3 species of Brucella can be differentiated in species level.
