. California fish and game. Fisheries -- California; Game and game-birds -- California; Fishes -- California; Animal Population Groups; Pêches; Gibier; Poissons. b Fig. 44. Oocysts of coccidia from California valley quail. forms of the oocysts are the agents of infection when ingested by the birds. Under the favorable conditions supplied by the intestinal tract, the life cycle of the coccidia continues for a time, with immature oocysts eventually being passed in the fecal droppings. The mature, infective forms of the oocysts remain viable over an extended period, and in pens upon the ground a serious source of infection is built up. When sus- ceptible birds are exposed to large numbers of mature oocysts they may become very ill and mortalities will probably occur. Birds raised on the ground, having ready access to their droppings, are reinfected easily. 1 Assistance in the preparation of this paper was given by the Work Projects Administration Official Project No. 65-2-07-344.
