Leishmaniosis caused by Leishmania infantum is an endemic zoonosis present in the Mediterranean area. Canidae (dog and fox) constitute the main reservoir hosts for the parasite, whilst wild rodents or the cat can be carriers of the protozoan and are considered as secondary potential reservoirs. This paper describes a case of disseminated feline leishmaniosis with cutaneous (ulcerative), viscera...

CASE SUMMARY This is the first clinical report of feline viscerocutaneous leishmaniosis caused by Leishmania infantum genotype E associated with an invasive squamous cell carcinoma (SCC) in a domestic cat from Portugal. Initially, the cat presented a single cutaneous lesion in the right nostril. A fine-needle aspiration was performed and Leishmania amastigotes were observed without the presence...

Introduction The visceral leishmaniosis (VL), or Calazar, is a chronic severe systemic disease, potentially fatal to humans. Currently, VL is the prototype of a specific immune dysfunction resulting from parasitism of leishmania donovani in macrophages, producing a broad spectrum of clinical and immunological reversible only with specific treatment. Serum Analysis from infected adult patients d...

The southern habitats of Croatia's gray wolf (Canis lupus) population are found in central and southern parts of Dalmatia. This region is recognized as an endemic region for canine visceral leishmaniosis, caused by Leishmania infantum. In November 2003, a 4-yr-old male gray wolf was found dead in the northwestern border of this endemic region. Pathologic and parasitologic analysis, confirmed by...

A case is reported of a 19-year-old woman, at week 24 of gestation, with visceral leishmaniosis. She was treated with meglumine antimoniate at a dose of 850 mg/day for 20 days. There occurred premature birth on day five of treatment and the neonate died one day after birth. Considering the importance of protozoiasis in our population and the rarity of the association with pregnancy, we resolved...

The increasing awareness that control of zoonotic visceral leishmaniosis (ZVL) depends on effective control of canine leishmaniosis has promoted research into leishmanial infection in dogs, but has also encouraged the indiscriminate elimination of seropositive dogs. Public health campaigns in various parts of the world (e.g. in Brazil and China) are designed to reduce the incidence of human ZVL...

We recently re-examined a case of Visceral Leishmaniasis, in a 36-year-old caucasian immune-competent men with an unusual clinical presentation. Together with symptoms and signs of a severe acute liver involvement, he presented weight loss, huge spleen enlargement, pancytopenia and increased ?-globulin serum level with a high polyclonal peak. He had no fever, but over-abundant night sweats were...
