Özet
Many reports have been published on the suspected vertical transmission of Encephalitozoon cuniculi; however, prior to 2003, these reports were based on circumstantial evidence, such as histopathological, immunohistochemical, or serological diagnosis of the infection. In 2003, vertical transmission of the parasite was confirmed by detection of E. cuniculi DNA in fetuses with the nested polymerase chain reaction (PCR) technique. However, the passage of the parasite to eyes of fetus during the intrauterine stage still requires verification. In the current study, natively infected with parasite spores female rabbits were mated with non-infected males. All resulting offspring that died before ten postpartum days were investigated using molecular techniques to confirm the intrauterine transmission of the parasite to the offspring' eyes. In total, 119 DNA samples from rabbit offspring tissues were collected from blood, kidney, brain, eye (both eyes were used as single samples), lung, placenta, liver and heart were used for PCR. Parasitic DNA in the eyes of offspring was detected (54%) 6 of 11 naturally seropositive mother rabbits. PCR results were found to be positive for the eyes of 63% (19/30) of the offsprings from seropositive rabbits. Therefore, mother rabbits naturally infected with E. cuniculi showed the molecular presence of the parasite in their offspring' eyes. Sequence analysis confirmed the partial DNA sequence data of E. cuniculi and blast analysis identified the agent as genotype I. These results confirm transmission of E. cuniculi to rabbit offspring' eyes in the intrauterine period. This is the first molecular evidence to show ocular transmission of the infection via an intrauterine route in rabbits.
