Giardia-infected domestic dogs from the field experiment were vaccinated with the entire repertoire of VSPs purified from DAS trophozoites or control PBS. The following clinical manifestations were analysed over a 4-month period: diarrhoea (Θ), weight loss (θ), anorexia (ϕ), lethargy (‡), high temperature (■), allergies (●) or no symptom (=).
