摘　　要：本文报道了患脑炎原虫病的病兔继发化脓性脑膜脑炎的病理变化。患脑炎原虫病的病兔由于脑组织的抵抗力低,故遭受葡萄球菌感染后,极易发生化脓性脑膜脑炎病变,此时,机体其他器官和组织的化脓性病变还不明显。临床上病兔常呈急性脓毒败血症表现,病情很快恶化。病理组织学上见脑软膜、脉络丛和脑室中均有大量嗜中性白细胞浸润,并且大部分嗜中性白细胞已发生变性和坏死,形成脓细胞。另见脑组织中有脓肿形成,在脑膜的小动脉分支发现有化脓性血栓或栓子。Pathological changes of rabbit with encephalitozoonosis and secondary suppurative meningoenceph-alitis were reported in this article. Rabbit with encephalitozoonosis was infected by staphlococcus very easilyand happened suppurative meningoencephalitis because of low resistance of its brain tissues. At the time, thepyogenic changes were not obvious in organs and tissues. Clinically, sick rabbit presented acute pyoseptice-mia and the condition deteriorated quickly. Histopathologically, there werea lot of neutrophils within cerebralpia mater, choroid plexus and encephalocoele. The great mass of neutrophils had occurred the degenerationand necrosis forming pyocyte. In addition, there was an abscess in brain tissue and purulent thrombus or em-bolus showed in arteriole.
