Rats genetically resistant to dextran and other agents producing the anaphylactoid reaction (NR rats), have a higher polymorph count than do rats which react to these agents (R rats).

NR rats do not develop polyarthritis when a hind paw is injected intradermally with Freund's adjuvant.

The polyarthritis produced by an intravenous injection of Mycoplasma arthritidis culture develops more slowly in NR rats than in R rats.

It is not clear whether the higher polymorph count in NR rats is a main factor in determining their resistance to adjuvant‐induced arthritis.
