Following domestication of the hamster its primary usefulness in human society was not that of a childhood pet, but as a laboratory research animal. In recent years rats and mice have become the laboratory animal of choice to the near exclusion of other viable rodent species.

Spermatogenesis in the Chinese hamster
The Anatomical Record, 1977AbstractIn this article a description of the process of spermatogenesis in the Chinese hamster is given.Spermiogenesis could be divided into 16 steps. The cycle of the seminiferous epithelium was divided into 12 stages, coinciding with the first 12 steps of spermiogenesis. The relative and absolute duration of the stages was determined. The duration of

The generally observed threshold type of response of the lethal effect of x rays on cultured mammaliam cells means that damage must be accumulated before a lethal response is prcduced. Surviving cells are, therefore, damaged cells. A study was undertaken,

Transmission of Scrapie in Hamsters
Journal of Infectious Diseases, 1985Hamsters developed scrapie 100-160 days after eating either scrapie-infected hamsters or infected brain. The clinical signs and neuropathology of scrapie transmitted by cannibalism were identical to those observed after intracerebral or intraperitoneal inoculation of the agent.

The hamster polyomavirus (HaPV) was originally described in 1967 by Graffi et al. as a virus associated with skin epithelioma of the Syrian hamster.(1–4) The tumors appear spontaneously in animals at about 3 months to more than 1 year of age in a laboratory colony bred in Berlin Buch, Germany (HaB).

Clostridial Enteropathies, Hamster [PDF]
, 1985 The cecum is usually distended with gas and a fetid watery or semiliquid content (Figs. 357, 358). Occasionally, the cecum is not distended and contains only a small amount of fluid. The cecal content may be cream, tan, or red (bloody) in appearance. Infrequently, pseudomembranous plaques are adhered to focal areas of the cecal mucosa.

Luteotropic Complex of the Hamster
Endocrinology, 1967Hypophysectomy, at any stage of pregnancy, interrupted gestation in the hamster. Pituitary removal at day 1, 4 or 8 of pregnancy resulted in rapid regression of the corpus luteum (CL), whereas after day 12, when the placenta has been established, the histologic integrity of the CL was maintained.
