Genetic quality control of experimental animals used in laboratory animal centers must be priority, to ensure that studies have reproducibility and also scientific validity. This research aimed to evaluate the genetic purity of the Wistar Kyoto rats at bioterio of the Faculty of Chemistry Sciences and Pharmacy at the University of San Carlos of Guatemala, “Dr. Amarillis Saravia Gómez”, which never had been genetically characterized. The D1Mgh6 and D17Mit3 microsatellites were analyzed because they have a high grade of polymorphism and allows to have a general vision of genetic characteristics of the strain, the analysis was performed by the polymerase chain reaction technique (PCR). The results of the genetic analysis showed that the colony of Wistar Kyoto rats corresponds to the estimated size for the microsatellite D17Mit3 (201 bp) as the genomic database rat and reported by Charles River Laboratories and the NIH. However, It doesn’t correspond to the estimated size of the microsatellite D1Mgh6 (147 bp). The WKY strain has been manage with an inbreeding method, that was confirmed by the results because D17Mit3 and D1Mg6 showed an homogenic and homoallelic condition, so these experimental animals can be used in trials as a inbreed model, because do not have the genetic characteristics expected for the WKY breed.
