网页2019年6月1日 · We established Cryptosporidium avian genotype III as a new species, C. proventriculi. • Cryptosporidium proventriculi was not infectious for budgerigars, chickens and mice. • Infection caused by C. proventriculi is localized in the proventriculus and ventriculus. • Oocysts of C. proventriculi are smaller than C. galli.
Proventriculus - an overview | ScienceDirect Topics
网页The proventriculus is a valve-like structure equipped with rearward-facing spines, which aids in rupture of the blood cells. The gelatinous dark brown masses eventually completely block the proventriculus. Fleas in this condition are said to be “blocked” because they are unable to pump blood into their stomachs [7–9].
