he nursing behavior of 5 female and 3 baby golden monkeyswas observed continuously with all occurrence method. The results showed that:(1)The baby monkey was nursed after being born about 3.1 hours;(2)The nursingperied can be classified as early middle,later and final stages;(3)The nursingcan be typed as physiological, transitional and psychological. The pathogenicity of Y. enterocolitic is closely related tospecific outer membrane proteins, which is associated with tissue invasion,coded by a virulent plasmid and dependent on temperature. Antiserum againstvirulent factors was produced by immunizing rabbits with the specific outermembrane proteins virulent strain absorbed with corresponding avirulent strain.26 strians of different serotype of Y. enterocolitica were detected withagglutination test.The results were comparable with that of VW-antigensdetermination,virulent plasmid examination and autogglutination test.
