LEISHMANIA ANTIBODIES IN CHILDREN'S SERUM SAMPLES IN CORRELATION WITH THE DISEASE IN DOGS

Sera of 489 children from Northern Greece aged between 6 months and 15 years of age and aflicted with different clinical entities, were tested for anti – Leishmania infantum specific IgG and IgM antibodies, using an ELISA (enzyme linked immunosorbent assay) technique. In this survey, a remarkably high percentage (8.5%) of hospitalized children reacted positively to this method. Twenty three out of 489 children (4.7%) had IgG antibodies, seventeen (3.5%) IgM, while two (0.4%) had both IgG and IgM antibodies against soluble antigen of L. infantum promastigotes. Females had a higher seropositivity than males. The highest prevalence was observed in males aged between 6 months and 5 years old (10 out of 19), while the lowest was observed also in males aged between 11 and 15 years old (5 out of 11). Seropositivity rate was higher in children below 5 years of age. Some epidemiologic, as well as clinical data of canine Leishmaniosis from Northern Greece are discussed.
