Behavior modulation of rats to a robotic rat in multi-rat interaction

Bioinspiration & Biomimetics, 2015
In this paper, we study the behavioral response of rats to a robotic rat during multi-rat interaction. Experiments are conducted in an open-field where a robotic rat called WR-5 is put together with three laboratory rats. WR-5 is following one rat (target), while avoiding the other two rats (outside observers) during interaction.

Transmission of Rat Virus in Milk of Rats

Journal of Infectious Diseases, 1974
blood, mammary glands, and milk removed from the stomachs of sucklings all had infectivity titers of approximately 10-3-10-4/0.1 ml when tested in rat embryo tissue cultures. Rat virus continued to be recoverable for a number of days after the appearance of circulating (HAI) antibodies.

Persistence of rat parvovirus in athymic rats

Archives of Virology, 1989
Euthymic (SD or outbred rnu/+) and athymic (rnu/rnu) rats were inoculated oronasally or intraperitoneally with the RV-Y strain of rat virus when they were 2 days or 4 weeks old. Clinical signs of infection in athymic infants were similar to those in euthymic infants, but significantly more athymic infants died.

Megacolon in Rats

Digestion, 2009
Four months of sigmoid colon intrinsic denervation of young male Wistar rats resulted in typical megacolon. Average 46.0% denervation of the Auerbach plexus was obtained by serosal application of benzalkonium chloride (0.2% v/v). Denervation was assessed by ganglion cell counts in a 480-nm extension of the treated segment.
