In addition, four T. spiralis proteins were found both 4 and 8 weeks after infection, namely hypothetical protein T01_16145 (KRY36525.1), conserved hypothetical protein (XP_003366234.1), calcium-dependent secretion activator 1 (XP_003375206.1) and protein CLEC16A (KRY38014.1). This evidence concerns the gene PROS1 and infection.
