Host-parasite relationship ofTrypanosoma corvi inOrnithomyia avicularia

Parasitology Research, 1989
The first description of an electron microscopic study of Trypanosoma corvi in the vector Ornithomyia avicularia is reported. There is a close association between vector and parasite in the midgut, ileum and rectum of the vector. The midgut distribution of parasites is determined by the peritrophic membrane, which confines the early infection to the ...

Comparison between Goldmann, Icare Pro and Corvis ST tonometry

Archivos de la Sociedad Española de Oftalmología (English Edition), 2014
To compare intraocular pressure (IOP) between the new non-contact tonometer Corvis ST (CST), the Goldmann applanation tonometry (GAT) and Icare Pro rebound tonometer (PRO).A total of 178 eyes of 178 healthy subjects were selected for the study. Measurements of IOP were made in a random order with GAT, PRO and CST.
