              Abstract
              
                              
                              
                              In this study, a total 28 Listeria monocytogenes 
                              field isolates obtained from different animal 
                              species were characterized phenotypically by CAMP 
                              test. Characterization by CAMP test on all the 28 
                              field isolates revealed positive reaction, of 
                              which twenty-three isolates showed characteristics 
                              enhancement of haemolytic zone with S. aureus on 5 
                              % Sheep Blood Agar (SBA) and five isolates showed 
                              weak haemolytic zone.
