“…Elevation of the cutoff avoids or diminishes the possibility of detecting cross-reactions (false positives), given that because of phylogenetic proximity, species of the genus Sarcocystis may present the same or similar surface proteins (SAVILLE et al, 2004). A serological study developed by Antonello et al (2015) on 189 samples from mares demonstrated that 64 (33.6%) of the animals were positive for antigens against S. neurona in IFAT. When these same samples were subjected to IFAT with Sarcocystis cruzi antigen (cattle-canids life cycle), 57 samples were positive, i.e.…”

“…IFAT has been conducted with cutoffs between 1:20 and 1:80. Even in some studies using low cutoffs (1:25 or 1:50), the frequencies of antibodies in horses were below 50% (Antonello et al, 2015;Cazarotto et al, 2016;Koch et al, 2019;Portella et al, 2017;Spohr et al, 2018). It is noteworthy that serological studies conducted using SnSAG4 ELISA reported higher antibody frequencies (higher than 60% in most regions) than studies conducted using IFAT (Table 2).…”
