Visceral hemangiosarcoma were analyzed at the Department of Veterinary Pathology Faculty Medicine, University Zagreb, over a 5-year period. From total 52 tumor masses in 31 dogs, histological growth patterns (cavernous, capillary or solid) and amount supporting stroma evaluated. Additionally, sections stained with toluidine blue for purpose mast cell detection their number was determined parenc...

In this paper, we present spatial analysis of the association between all incidents cases of human Visceral Leishmaniasis and seropositive dogs, from 1994 to 1997 in Belo Horizonte, a large Brazilian city. We geocoded 158 human cases and 11,048 seropositive dogs and compared canine prevalence rates with Human Bayesian Incidence rates in the same areas. We also used Knox's test to evaluate the h...

Canine infections with Leishmania infantum are important as a cause of serious disease in the dog and as a reservoir for human visceral leishmaniasis (VL). Accurate diagnosis of canine infections is essential to the veterinary community and for VL surveillance programs. A standardized ELISA using a purified recombinant antigen (rK39) specific to VL was compared to the immunofluorescent antibody...

This study aimed to analyse the spatial distribution of human (2007-2013) and canine (2013) visceral leishmaniasis (VL) in the city of Araçuaí, Minas Gerais, Brazil, and identify the socio-environmental factors related to their occurrence. The spatial distribution of human and canine cases was analysed by kernel density estimation (KDE) and the K function. The KDE values were analysed for corre...

The mathematical model described by Dye (1996) condemned the epidemiological canine visceral leishmaniasis control campaign, considering it non-efficient. Using this model, we mathematically demonstrate that the control is not efficient, only at low kappa values (rate at which latent and infectious dogs are lost by the destruction program) which match the canine seropositivity observed in the f...

et al. Quantitative nucleic acid sequence-based assay as a new molecular tool for the detection and quantifi cation of Leish-mania parasites in skin biopsies.ther observations on clinical, histopatho-logical, and immunological features of borderline disseminated cutaneous leish-maniasis caused by Leishmania (Leish-mania) amazonensis. leishmaniasis due to Leishmania (Leish-mania) amazonensis in ...

Leishmaniasis is not a single disease; rather, it is a collection of diseases caused by several different species of Leishmania, each of which has its own potential to cause a characteristic set of symptoms in man. No reliable estimates of the incidence and prevalence of leishmaniasis exist. It has been estimated that there are 400 000 new cases of leishmaniasis every year,' but the importance ...

Leishmaniases, caused by the intracellular protozoan Leishmania infantum, are an endemic zoonosis in the Mediterranean basin. Dogs are considered the major host for these parasites, and the main reservoir for human visceral infection. Parasites are transmitted by the bite of phlebotomine sand flies, being Phlebotomus perniciosus and P. ariasi the proven vectors in Portugal. The global climate c...

In this work, we investigated the association between the disruption of splenic lymphoid tissue and the severity of visceral leishmaniasis in dogs. Clinical and laboratory data from 206 dogs were reviewed. Spleen sections collected during the euthanasia of these animals were analyzed, and the splenic lymphoid tissue samples were classified as well organized (spleen type 1), slightly disorganize...
