“…Buxon et al (2007) reported that 2% of neonatal lamb mortality was due to toxoplasmosis (Buxon et al, 2007). Reif et al (1989) determined T. gondii seropositivity at the rate of 27% in 211 sheep blood sera in Peru and by comparing the difference between seropositivity and seronegativity, they revealed the relationship between toxoplasmosis and lamb mortality as well as sheep infertility. In seropositive sheep, the rate of neonatal lamb mortality was determined as 30.7% and in seronegative sheep, the rate was determined as 13.6% in the USA (Huffman et al, 1985).…”

In this study, it was aimed to reveal the relationship between neonatal lamb mortality and toxoplasmosis. The study was carried out in a sheep farm that declared the death of lambs. Brood ewes (N= 50) were included into the study and they were divided into 2 groups. The first group consisted of 25 sheep whose lambs had died, and the second group consisted of 25 sheep whose lambs were alive. Blood samples were collected from the two groups and the blood sera were obtained. The sera were examined with the Sabin-Feldman Dye Test for the antibodies against Toxoplasma gondii (T. gondii). Of the 50 blood sera examined, 29 (58%) were positive for T. gondii, 20 (80%) of which were from the sheep whose lambs had died. On the other hand, only 9 (36%) of 25 blood sera from the sheep with healthy lambs were found to be positive. The frequency of T. gondii infestation was statistically evaluated by chi-square test and the difference between the two groups was found to be significant. (p<0.05). The results of the study showed that toxoplasmosis can play an important role in lamb mortality.

“…Furthermore, contaminated sheep meat is a source of T. gondii infection for humans (Soulsby, 1986). There are several studies showing relationship between antibody titers against T. gondii in the ewes and neonatal mortality of lambs (Buxon et al, 2007, Reif et al, 1989.…”
