Product code CBHNU
Strain Description Mutant inbred
Coat Colour Black hooded (a, B, C, h)
MHC Haplotype RT1c
  • Good breeding performance.
  • Homozygotes have little or no hair and are athymic.
  • Heterozygotes have hair and functioning thymus.
  • Prone to dust in their eyes as no eyelashes.
  • Similar dysgenesis to nude mutation in mice.
  • Cell mediated immunity greatly reduced or absent with a marked reduction of T-lymphocyte function.
  • Extremely susceptible to infection with Clostridium piliformie.

Product code PKD
Strain Description Inbred
Coat Colour Albino (a, B, c, h)
MHC Haplotype RT1l
  • Poor breeding performance; docile.
  • Lewis (LEW/SsNArc) rat is the background strain.
  • Lewis polycystic kidney (LPK) model of autosomal-recessive polycystic kidney disease (ARPKD).
  • Lewis rats (LEW/SsNArc) with PKD arose as a spontaneous mutation of Nek8 (McCooke, et al., A novel mutation causing Nephronophthisis in the Lewis Polycystic Kidney rat localises to a conserved RCC1 domain in Nek8. BMC Genomics, 2012, 13: 393).
  • Bilateral PKD starts as early as 3 weeks and progresses with age in homozygous animals (Kidney Blood Pressure Research 2007; 30: 129-144).
  • Develop hypertension in homozygous animals and susceptible to induction of experimental allergic encephalomyelitis.
