Abstract EN
Toxoplasma gondii is the causative agent of a major zoonosis with cosmopolitan distribution and is known to be transmitted mainly by the ingestion of undercooked or raw animal products.
Drinking unpasteurized goat’s milk is a risk factor associated with human toxoplasmosis.
However, very little is known about the excretion of DNA in goat milk.
Aim of the present study was to determine the seroprevalence of T.
gondii infection using a modified agglutination test (MAT), to detect T.
gondii DNA by nested-PCR (n-PCR) in samples of blood and milk from seropositive goats, and to genotype DNA isolates using 11 molecular markers in 127 adult lactating goats from 6 farms in Italy.
Positive MAT results were found in 60.6% of goats while 13% of blood and milk samples from seropositive goats were positive to n-PCR.
A kappa coefficient of 1 indicated a perfect agreement between blood and milk n-PCR.
Genetic characterization of isolates revealed the occurrence of genotype III (n=7), genotype I (n=1), and atypical genotypes with hints for genotype I (n=2).
Our results suggest that the risk of excretion of Toxoplasma tachyzoites might frequently occur in milk of seropositive goats testing positive to n-PCR on blood.
