Due to the growing popularity of reptiles as a household animals and the development of numerous reptile farms, they have become a common sight in veterinary clinics. As parasitic infections represent a serious problem among pet reptiles obtained by captive breeding and from pet shops, the purpose of the present study was to determine the species composition of parasites present in reptiles bred privately or in Cracow Zoological Garden, and those obtained from pet shops. Fecal samples collected from 91 reptiles (30 turtles, 40 lizards, and 21 snakes) were examined using the quantitative McMaster method. Parasite eggs or protozoan oocysts were identified in 59.3% of samples. These included the eggs of the Pharyngodonidae, Ascarididae and Rhabditoidea (Nematoda), and Trematoda, as well as oocysts of Isospora and Eimeria. In addition, pseudoparasites belonging to the Mesostigmata, Demodecidae and Myobiidae were found.
