Changes in serum concentration of phagocytosis-stimulating factor in experimentally induced bovine anaplasmosis:
American Journal of Veterinary Research
|May 1, 1976
Abstract:
To determine whether correlation exists between serum concentration of phagocytosis-stimulating factor (PSF) and in vivo phagocytic activity, 2 splenectomized steers were inoculated with Anaplasma marginale, and their serum PSF concentrations were monitored. At the time of the anemic crisis, serum PSF concentrations were elevated five to tenfold.
