Macrophage engulfment percentage and phagocytic index
were evaluated by the formulas (Tatarczuch et al.
Mean [+ or -] SE, n: 3 in each group, phagocytic rate (Rp), phagocytic index
Determination of phagocytic activity and phagocytic index
Phagocytic activity was determined according to Kawahara et al.
(a) showed significantly higher response in all three polysaccharides administered groups.
2% humic acids on some parameters of innate immunity (serum bactericidal activity, phagocytic index
, bacterial agglutination, respiratory burst, lysozyme activity) in commercial laying hens in the post-molt phase.
The results were expressed as percentage of heterophils with bacteria and phagocytic index
(PI), where PI = (the percentage of heterophils containing bacteria) x (the average number of bacteria per ingesting heterophil).
Nevertheless, in marine bivalves, the phagocytic index
grows lower and lower from autumn (September) to the spawning period (June-July) (Duchemin et al.
The phagocytic index
of the extract and fractions was determined using carbon clearance test.
