Abstract

The development of Besnoitia wallacei was studied in 13 cats fed on tissues of mice and rats previously infected with B. wallacei. The cats were serially killed between Day 1 and Day 16 of infection, and histological sections from the liver and intestines were examined. Asexual stages were seen in both the small intestines and the liver between Day 6 and Day 16 post-infection. Mature microschizonts in intestinal epithelial cells measured 22.6 microns x 14.7 microns (n = 15). Macroschizonts in intestinal lamina propria measured 66.6 microns x 50.3 microns (n = 25). Those in the liver measured 70.9 microns x 55.0 microns (n = 5). Sexual stages were seen in epithelial cells of the small intestines only.

摘要

在13只以先前感染了华莱士贝斯诺孢子虫（Besnoitia wallacei）的小鼠和大鼠组织为食的猫身上，对华莱士贝斯诺孢子虫的发育情况进行了研究。在感染后的第1天至第16天期间，这些猫被相继处死，并检查了肝脏和肠道的组织切片。感染后第6天至第16天期间，在小肠和肝脏中均观察到无性阶段。肠道上皮细胞中的成熟微裂殖体大小为22.6微米×14.7微米（n = 15）。肠道固有层中的大裂殖体大小为66.6微米×50.3微米（n = 25）。肝脏中的大裂殖体大小为70.9微米×55.0微米（n = 5）。仅在小肠上皮细胞中观察到有性阶段。
