Abstract

In the present study 44 brucella strains were isolated from different animals (20 from cows, 2 from buffaloes and 22 from sheep) at different localities in Egypt. Typing of these isolates revealed 5 strains (11.4%) Brucella abortus biotype 3, 2 strains (4.6%) Brucella abortus biotype 7 and 37 strains (84%) Brucella melitensis biotype 3. Brucella abortus biotype 3 was recovered from cows & buffaloes, Brucella abortus biotype 7 was isolated from cows, whereas Brucella melitensis biotype 3 was isolated from sheep & cows.
The results revealed that Brucella melitensis biotype 3 is the prevalent type among sheep & cows. Isolation of Brucella abortus biotype 7 is con sidered thefirst record for this biotype in Egypt indicating the danger of importation of animals from infected localities.
