Schizogony and Gametocyte Development of <i>Leucocytozoon berestneffi</i> in the Yellow‐Billed Magpie, <i>Pica nuttalli</i>*

Abstract

SYNOPSIS. Histological examination of organs from 72 infected birds exhibited schizogonic stages in hepatic, spleen and, to a lesser extent, kidney cells; little or no distortion of the host cell was noted. Feulgen‐positive schizonts were small and occurred abundantly in scattered sections of the infected organs. No megaloschizonts were found. Evidence is presented that gametocytes found in the circulating blood develop exclusively in lymphocytes.
