Abstract
Leishmania infantum infection including treatment and follow up in domestic animals other than dogs and cats has not been described at this moment. This article describes the anti-Leishmania treatment and follow-up of a ferret (Mustela putorius furo) with leishmaniosis. A combined therapeutic protocol established for the patient, not yet approved for ferrets, was a combination of meglumine antimoniate plus allopurinol. A follow-up was established monthly during the first year in order to monitor the health condition of the patient. Six months after commencing allopurinol therapy, xanthine crystalluria was observed in urine sediment with no other urine alterations detected by urine analysis. The ferret worsened progressively with diarrhoea and weight loss after cohabiting with another ferret diagnosed with cryptosporidiosis. Cryptosporidium parvum was isolated in faecal samples from the patient detected by three different methods including Ziehl-Neelsen staining, a qualitative test to detection of C. parvum antigens and finally a specific molecular analysis to characterize the species. To the best of the authors´ knowledge, this is the first report providing information about anti-Leishmania protocol therapy used and follow-up in a domestic ferret with clinical leishmaniosis. Veterinarians practicing in endemic areas should be aware of this infection in ferrets at risk and their susceptibility especially when immunosuppressive conditions are present.

IgG avidity index and complete blood count as biomarkers of clinical disease in naturally infected dogs with Leishmania infantum. Vet Parasitol 2018; 261:96-103.

Abstract
Canine visceral leishmaniosis (CVL), a parasitic disease caused by Leishmania infantum, may evolve to a chronic condition and lead to death. Evaluation of infected dogs is important to establish the clinical and laboratory parameters involved in the evolution of the disease. The objectives of the present study were to discriminate a canine population (n = 52) into sub-clinical and clinically affected dogs based on signs and scores, to evaluate the hematological, biochemical, histopathological and parasitological parameters of the two dog groups, and to analyze the results by multivariate regression analysis with the aim of establishing biomarkers of CVL clinical disease. The most common signs observed in the clinically affected dogs (n = 29) were hyperkeratosis, weight loss, onychogryphosis, pale mucosa and lymphadenomegaly. In the multivariate analysis, animals presenting high IgG avidity index and low red blood, lymphocyte and eosinophil counts, and low serum urea concentration had an increased probability of being classified as clinically affected (p < 0.05). All five parameters were considered to be strong biomarkers for monitoring the clinical disease, while IgG avidity percentage was strongly correlated with the number of clinical signs and could function as an indicator of the duration of infection. This is the first report on the application of IgG avidity and of multivariate regression analysis in establishing associations between the clinical signs of CVL and host biomarkers. Since avidity index (AI) percentages were strongly correlated with the number of clinical signs, it could be useful in clinical practice for auxiliary diagnosis of CVL and monitoring disease progression. A limitation of this study is the lack of information on co-infections by Anaplasma platys, Babesia canis vogeli, Ehrlichia canis and Hepatozoon canis. Therefore future studies should evaluate the influence of such co-infections on the associations studied using multivariate methods with larger samples.

Abstract
The aim of this study was to evaluate the effects of domperidone, a dopamine D2 receptor antagonist, in dogs naturally infected by Leishmania infantum. Ninety-eight dogs were treated with single-agent domperidone at 1mg/kg twice a day orally for 1 month. Clinical, serological, biochemical and immunological examinations were conducted for the following 12 months. Domperidone was effective in controlling and reducing clinical signs and antibody titre. Significant decreases in reciprocal serum antibodies were seen in 74.3% of the dogs with mild clinical signs and 40% of the dogs became seronegative. In dogs with several clinical signs and high antibody titres, clinical improvement occurred in 86% of animals and the reciprocal serum antibody titres decreased in 38% of these dogs. A significant increase was noted in the immune cellular status, as measured by the leishmanin skin test and a lymphocyte proliferation assay.

Abstract
Six healthy beagle dogs were infected with Leishmania infantum (MCAN/ES/92/BCN-83/MON-1) by intravenous inoculation of 5 x 10(7) promastigotes and two others were used as controls. When animals showed clinical signs of disease at 29, 37, 41 and 45 weeks post-infection (p.i.), they were treated with meglumine antimoniate (20.4 mg Sb/kg/12 h) subcutaneously for two periods of 10 days each. Sera were tested periodically for Leishmania antibodies by Dot-ELISA, ELISA and Western blot (WB). Aspirates of popliteal lymph node (PLN), peripheral blood sample (PB) and healthy skin were cultured in NNN and Schneider's medium. PLNs were positive between 8 and 20 weeks p.i. and in one animal PB was positive 6 weeks p.i. Samples of healthy skin, obtained before treatment, were also positive. Dot-ELISA and ELISA detected specific antibodies at an early stage between 4 and 12 weeks p.i and surpassed the cut-off between 16-24 weeks p.i., while the WB was positive between 10-19 weeks p.i. The pattern of bands revealed during the first stages of infection was variable and only in two cases did the positivity start with bands of low molecular weight (12-14 kD); the number of bands increased until 15-24 weeks p.i., after which sera revealed a complete pattern of bands, from 12 to 85 kD, in the antigen of Leishmania. After treatment the clinical improvement of the animals was accompanied by a decrease in antibody titers (Dot-ELISA and ELISA) although the parasites remained in the PLN. This was reflected in the WB by a decrease in the intensity of bands, especially those in the region of 12-30 kD. A new increase in the antibody levels between 3 and 5 months after terminating the therapy was detected in the WB by a restoration of the initial complete pattern of bands.
