Bilateral ovarian cysts originating from rete ovarii in an African green monkey (Cercopithecus aethiops).

Experimental Poliomyelitis in Cercopithecus Aethiops Sabaeus (the Green African Monkey) by Oral and Other Routes

The green African monkey, Cercopithecus aethiops sabaeus, has been infected with experimental poliomyelitis after feeding artificially contaminated food. This species is also highly susceptible to intracerebral, intranasal, and intraabdominal inoculations. In one experiment with a human stool from a case of poliomyelitis, Cercopithecus was more susceptible to intranasal and to intraabdominal in...

Ovarian cysts in MRL / MpJ mice are derived from the extraovarian rete: a developmental study.

MRL/MpJ (MRL) mice, commonly used as a model for autoimmune disease, have a high frequency of ovarian cysts originating from the rete ovarii. In the present study, to clarify how the rete ovarii, which are remnants of mesonephric tubules during embryogenesis, progress to cystic formation with aging, the morphology of MRL rete ovarii was analyzed and compared with that of normal C57BL/6N (B6) mi...

Yersinia enterocolitica Infection in a Vervet Monkey (Cercopithecus aethiops) in Iran

  A vervet monkey (Cercopithecus aethiops) housed at quarantine of Razi vaccine and serum research institute died following a few days of sickness. Multiple abscesses on the surface and inside the liver and enlargement of spleen with pinpoint white spot were the most prominent macroscopic features. We examined the organs of the dead monkey and Yersinia enterocolitica was isolated. In histopatho...

A Case of a Spontaneous Lumbar Disc Prolapse in an African Green Monkey ( Chlorocebus aethiops )

Squamous metaplasia of the rete ovarii in a Zebu cow

BACKGROUND Stratified keratinizing squamous epithelium in the ovary has been associated with the diagnosis of ovarian teratoma in cows. Recently, the diagnosis of "epidermoid cyst" has been proposed. A case of squamous metaplasia of the rete ovarii in a Zebu cow is described in this report. CASE PRESENTATION A crossbreed Zebu cow had both ovaries enlarged with multiple cysts. Most cysts were ...
