METHOD FOR PREDICTING SECONDARY IMMUNODEFICIENCY IN CATTLE Russian patent published in 2006 - IPC G01N33/53 G01N33/49 

FIELD: veterinary science.

SUBSTANCE: the present innovation deals with applying reaction of agglutination inhibiting including dilution of test-sera and tested sera with sodium chloride physiological solution followed by their incubation at 37° C, performing reaction of hemagglutination due to double serial dilutions, mixing tested serumal dilutions with a diagnostic kit. Then comes repeated incubation at 37° C to detect the index of inhibition, moreover, reaction of hemagglutination due to the method of double serial dilutions should be fulfilled on a plot and at the index of inhibition being either above or equal to 1.1 it is possible to diagnose secondary immunodeficiency. The innovation enables to decrease labor capacity of the method described, enables to detect all immunodeficient animals and adapt this method to mass trials of blood sera in the field of veterinary science.

EFFECT: increased sensitivity of the method.
