This word was used in a championship spellingbee for highschool kids. Seems rough to me.
" Our goal is to
increase our knowledge and understanding of risks associated with
cryptosporidiosis. To achieve this, we will utilize a gnotobiotic pig model and
pursue three objectives: 1) Assess and compare the pathogenesis (infectivity
and virulence) of C.parvum in neonatal versus older gnotobiotic pigs; 2)
Evaluate the susceptibility and clinical responses of immunosuppressed
gnotobiotic pigs to C.parvum; and 3) Characterize the humoral (B cell),
cellular (T cell), and cytokine immune responses in gnotobiotic pigs with
cryptosporidiosis.

Definition:gnotobiotics:
The science of rearing laboratory animals the microfauna and microflora of which are
specifally known in their entirety.
