title: Leishmania infantum in a Central Italy dog shelter: retrospective study of serologic reactivity during a 4-year period in a confined dog population subjected to preventive and therapeutic treatment.
abstract: Leishmaniasis from Leishmania infantum is a parasitary zoonotic disease and a serious problem to public health. Guidelines from Italian Health Authority (Istituto Superiore di Sanità) suggest to control the zoonotic visceral leishmaniasis canine reservoir in endemic areas using an association of preventive and therapeutic tools. Moreover, in literature there are no studies about the long term effects on the disease seroprevalence and incidence in relation to this "holistic" approach. Past research has considered the effects of the alternative employment of preventive or therapeutic treatment, usually for limited periods. In this retrospective study the patterns of seroprevalence and incidence of leishmaniasis in a dog shelter sited in an endemic area of Central Italy are described throughout a 4-year period. Both preventive spot-on tools (imidacloprid/permetrin) and therapeutic protocols based on antimonials and allopurinol were administered. The results showed a progressive reduction of prevalence and incidence of serological reactivity to L. infantum, corroborating the effectiveness of the treatment administered to the animals. Significant improvements from the beginning to the end of the 4-year period were reported, considering both prevalence and incidence. A very low rate of relapses (8% in a pool of 67 subjects positive since 2004; 10.2% among all subjects enrolled in the study) was achieved.
