An epidemiological survey on the leishmaniosis in the Campo de Nijar' s area (Almeria)
Abstract
We have realised an epidemiological study on the Leishmaniosis in the Southem area from Subdesertic Mediterranean bioclimatic zone, of the Almeria' s province (Campo de Níjar, Southeast Spain). The Montenegro Skin test (IDR) was applied to a sample of human population: of 1.370 individuals inoculated, only 33 (2'4 %) were positives (induration >= 5 mm). The canine population was analysed by Immunofluorescent Antibody test (IFI): of 286 sample of serum analysed, 174 were negatives (60'9%) and 112 were with antibody titles >= 20 (39'2 % seropositivites); of these only 13 were with title >= 160 (seroprevalence of 4'5 %).
The study was completed with the capture of vectors: 1) with sticky traps we capture 216 specimens belonging to the species S. minuta (62 %), P. perniciosus, (34'3 %), and P. ariasi and P. papatasi (3 '7 %). 2) With CDC traps we capture 790 specimens to the species P. perniciosus (73 %), P. papatas; (22'2), P. ariasi, P. longicuspis, P. sergenti, P. alexandri and S. minuta (4' 8 %). Although we have diseccionate 530 specimens female none of them was parasitized by Leishmania.
