Systems for genetically standardizing inbred strains of rodents have been well documented. With the internationalization of biomedical research, it has become necessary for multi-national laboratory animal suppliers to globally standardize more commonly used non-inbred toxicology models such as the Sprague Dawley and Hanover Wistar rat stocks. This paper describes one such breeding system, the ...

The present work investigated whether the number of rats housed in a cage affects exploration of an elevated plus-maze. Male Wistar-derived rats were kept 1, 2, 3, 4, 6, 8, 12, 16, or 24 to same size cages either for 1 or 14 days and tested in the elevated plus-maze. Rats kept 6 to a cage were arbitrarily considered controls because this is the housing condition adopted in many laboratories, ou...

We pref ered a square type rat-trap to a round type one according to the knowledge of the last survey. Traps were set in the afternoon and were inspected in the next morning. The traps which captured a rat were transported in canvas bags to the laboratory for a further examination. The team used to work for a week in each theater. The rats, in the laboratory, were compulsed to urinate. The urin...

Purpose: The purpose of this study is to model Cryptosporidiosis in laboratory animals. The parasites were inoculated into animalsand thenmultiplied. The process of proliferation was compared to controlCryptosporidiosis in humans. Materials and Methods: Twenty-five laboratory mice (4-7 days of age) and twenty-five laboratory rats (5 days of age) were assigned to the category I while the cat...
