The objective of this study was to establish dermatological diseases etiology in laboratory animals. Were examined clinically and dermatologically a number of 403 rodents of different ages and sexes, respectively 173 guinea pigs (Cavia porcellus), 120 rabbits (Orytolagus cuniculus), 80 rats (Rattus norvegicus) and 30 mice (Mus musculus). Dermatological diseases identified in guinea pigs were represented by malophagosis (Gliricola porcelli in 111/173 - 64,16%), listrophorosis (Chirodiscoides caviae in 111/173 - 64,16%), demodicosis (Demodex caviae in 2/173 - 1,15%) and tricophytosis (Trichophyton mentagrophytes in 3/173 – 1,73%). Rats were infected only with Notoedres muris (56/80 respectively 70%). In rabbits was diagnosed (Psoroptes cuniculi in 7/120 – 5,83%), listrophorosis (Listrophorus gibbus in 2/120 – 1,66%) and cheyletiellosis (Cheiletiella parasitovorax in 2/120 – 1,66% ). In mice have evolved associated infestations with Mycoptes musculinus (20/30 - 66,66%), Myobia musculi (12/30 - 40%) and Chirodiscoides caviae (3/30 - 10%). Chirodiscoides caviae, mite with specific parasitism in guinea pig, has been isolated from mice with skin lesions. Were recorded two zoonotic diseases: tricophytosis and cheyletiellosis
