U radu je opisan jedan sluèaj pravog hermafroditizma kod svinje Sus scrofa domestica<br />
gajene na Fakultetu veterinarske medicine. Opservacija spoljašnje morfologije navela<br />
nas je na pretpostavku da je reè o pravom hermafroditizmu obzirom da je konstantovano<br />
prisustvo muških i enskih polnih organa (vulva sa hipertrofiranim klitorisom, testisi i<br />
penis). Patomorfološkim analizama takoðe je potvrðen dualizam muških i enskih polnih<br />
organa, pa je odluèeno da se pristupi hromozomskim analizama ove ivotinje primenom<br />
modifikovane metode Evans-a i O’Riordan-a (1975). Analizom kariotipa limfocita<br />
periferne krvi svinje utvrðen je mozaicizam polnih hromozoma tipa 2n=38,XY/XX uz<br />
otkriæe odreðenog procenta aneuploidnih æelija. S obzirom na izgled spoljašnjih<br />
genitalnih organa (prisutni su vulva sa hipertrofiranim klitorisom, testisi i penis) i<br />
unutrašnjih genitalnih organa (smanjeni testisi, prisutni ovarijumi i uterus) i hromozomske<br />
analize moemo pretpostaviti da postoje dva moguæa uzroka hermafroditizma<br />
kod ove ivotinje: mozaicizam i himerizam.<br />
KARYOTYPE ANALYSIS OF HERMAPHRODITE SWINE<br />
A case of hermaphrodite swine Sus scrofa domestica housed in the Faculty of Veterinary<br />
Medicine was described. After observation of outer morphology we supposed that it is a<br />
question of true hermaphroditism because the swine had male and female reproductive<br />
organs (vulvae with hypertrophed clitoris, testes and penis). Pathomorphologic analyses<br />
also affirmed dualism of male and female reproductive organs, so we decided to perform<br />
chromosome analyses using modificated method of Evans-a i O’Riordan-a (1975).<br />
Karyotype analyses of lympocytes from peripheral blood revelaled mosaicism of<br />
gonosomes 2n = 38,XY/XX and certain presence of aneuploid cells. Having in mind the<br />
view of outer genital organs (vulvae with hypertrophed clitoris, testes and penis) and internal<br />
genital organs (reduced testes, appearance of ovaries and uterus) we can assumed<br />
that there are two possible causes of hermaphroditism in this animal: mosaicism and<br />
chimerism.
