Origin: Set of nine parallel inbred strains designated IIMa to IIMi from a single outbred colony of albino rats in Buenos Aires, Argentina in 1947. The ancestors came from Europe in 1917. All strains were selected for large body weight and high fertility with each colony consisting of one male and 4-6 females, with inbreeding due to full and half-sib mating. One strain designated IIMß becomes obese with mild glucose intolerance and glycosurea in older obese rats (Calderari et al 1987).
