Rabbit antibodies against Toxoplasma Hsp20 are able to reduce parasite invasion and gliding motility in Toxoplasma gondii and parasite invasion in Neospora caninum

► Hsp20 shows a high degree of conservation among Apicomplexas. ► Rabbit anti-Toxoplasma gondii Hsp20 serum was able to recognize the Neospora caninum counterpart. ► N. caninum Hsp20 is localized at the parasite's pellicle. ► Anti-TgHsp20 serum reduced T. gondii invasion and gliding and N. caninum invasion. ► TgHsp20 showed to localize at the plasma membrane, IMC and basal complex.
