Two of three dogs shed oocysts when they were re-exposed 18–20 months after the first challenge; two other dogs re-exposed earlier, only 8 months after the primary exposure, did not produce oocysts. These results suggest that dogs may become refractory to shedding N. caninum oocysts for a period approximately between 8 and 18 months after a primary infection; however, this possibility requires statistical validation by testing of more dogs. The development of a high antibody titer did not ensure that a dog would completely resist shedding oocysts after consuming an infected meal. Oocyst production was also compared between puppies and adult dogs with primary infections. Twelve puppies (three from the present study and nine from a previous study) shed significantly more oocysts (mean: 166,400) compared with five adult dogs following primary exposure (mean: 2900), indicating that a dog's age can influence N. caninum oocyst production (P = 0.02).Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2013-10-29T14:31:17Z No. of bitstreams: 1 L.F.P.
