Resumo

Background: Leishmaniosis are anthropozoonosis caused by protozoa of the genus Leishmania, representing a complex of diseases with significant diversity epidemiological and clinical spectrum and can affect 40% of the canine population. Infected dogs may be asymptomatic or may develop canine leishmaniasis (CL), a severe and progressive disease associated with the appearance of clinical signs. Serological tests are frequently used for screening of dogs, however, these techniques present limitations in terms of reproducibility and specificity. In this way, information on the geographical distribution and prevalence of CL is essential to the implementation of appropriate control measures. Therefore, the aim of this study was to determine geographical variations in clinical signs and prevalence of Leishmania sp. infections from dogs in Fortaleza, Ceará state, Brazil. Materials, Methods & Results: Bone marrow samples of 2829 domestic dogs were collected by puncture for parasitological diagnosis of canine leishmaniasis (CL), being considered positive by the presence of Leishmania sp. All dogs were examined and clinical signs were classified as score 0: no clinical signs, score 1: skin lesions, score 2: visceral signs and score 3: skin lesions + visceral signs. Kruskal-Wallis (P <0.05) was used to compare the scores and parasitological diagnosis among the seven regions of Fortaleza. So, it was observed that 72% of dogs were positive and the regions I and V had the highest prevalence (78.3% and 80% respectively), no significant differences among the seven regions. Asymptomatic dogs represented 55% of infected dogs, and the main clinical sign, among symptomatic dogs (45%), was skin lesion, visualized in 43% of dogs. Furthermore, 70% of all dogs had ectoparasites(...)(AU)
