Abstract
The aim of the present study was to assess the occurrence of antibodies to Toxoplasma gondii and to detect genomic DNA of the parasite in the reproductive organs, fetuses and fetal membranes of sheep in slaughterhouses in the state of Pernambuco, Brazil. The Indirect Immunofluorescence technique (IFA) was used for screening. The Polymerase Chain Reaction (PCR) was used to detect DNA of T. gondii in the animals that were positive in the serology. In the serology, 13/50 samples were positive and genomic DNA of T. gondii was detected in one uterus, tube, ovary, placenta and fetus (heart, brain and umbilical cord) sample from a sheep that was positive in the serology. The present study provides evidence of the occurrence of T. gondii DNA in the organs of the reproductive system, placenta and fetus of a naturally infected sheep.
