Parasitic


Definition:

  • (a.) Alt. of Parasitical

Example Sentences:

  • (20) Pretreatment of G6PD(+) cells with ascorbate caused a slight enhancement in parasite development, while in G6PD(-) cells a suppressive effect on the plasmodia was demonstrated.

Saprophytic


Definition:

  • (a.) Feeding or growing upon decaying animal or vegetable matter; pertaining to a saprophyte or the saprophytes.

Example Sentences:

  • (1) Aspergillomas generally arise from saprophytic colonization of a pre-existing pulmonary cavity with Aspergillus, and may be complicated by life-threatening hemoptosis.

  • (8) Proliferation of the saprophytic strains G-45, K-1028 (serovar not identified) and of the pathogenic strain VGNKI-3 (serovar canicola) of Leptospirae was obtained on a serum-free medium with the addition of saturated fatty acids.
