Abstract

SUMMARY The variation of the anti-Leishmania antibodies titres in a cohort of 46 dogs were studied in two areas in northern Morocco during the period (from July 1996 to July1997) by using the immunofluorescence test (IFAT) and counter-immunoelectrophoresis (CIEP). The 46 dogs had titres ≥ 100 and showed specific anti-L.infantum bands by CIEP. Dogs were divided in three groups : group 1 included 20 dogs which produced high antibody titres (titre ≥ 800) and developed clinical and fatal canine leishmaniasis. Group 2 had 16 dogs with low titres following infection and which remained asymptomatic during the period of follow up. In group 3, the titres ≥ 100 of 10 animals decreased to 50 and became negative by the end of the study. The disease was more prevalent in older dogs than in younger ones.
