Virulence and susceptibility to phagocytosis of Pseudomonas pseudomallei R- and S-forms for ground squirrels (Citellus citellus L.).

Abstract

Virulence and susceptibility to phagocytosis of Pseudomonas pseudomallei R- and S-forms for ground squirrels were studied. The alveolar macrophages and blood leucocytes (polymorphonuclear and mononuclear) was used. S-forms survived and multiplied intracellularly more actively in alveolar macrophages than R-forms and their virulence was considerably higher.
