Vector-borne diseases (VBDs) are prevalently investigated in dogs. Studies on feline VBDs are scant, though feline leishmaniosis (FeL) is increasingly recognised as a disease of cats in endemic areas. Comprehensive investigations on the distribution of VBDs in populations of cats and dogs living in relatively small geographical areas, such as islands, are currently lacking. In this study the prevalence of Leishmania infantum and other VBD pathogens was assessed in cohorts of cats and dogs living in the Aeolian Islands...

BACKGROUND: A wide spectrum of clinical manifestations and immune responses exist in canine L. infantum infection. Ibizan hounds are more "resistant" to disease than other dog breeds. Recognition of pathogen-associated molecule patterns by toll like receptors (TLRs) rapidly triggers a variety of anti-microbial immune responses through the induction of pro-inflammatory cytokines such as TNF-α and IL-6 which may play an important role in controlling Leishmania infection. The main objective of this study was to investigate and compare the effect of a TLR2 agonist (TLR2a) alone or in combination with L...

BACKGROUND: Normal-looking skin of dogs with leishmaniosis frequently shows microscopic lesions along with the presence of Leishmania amastigotes. However, histological lesions with or without detection of amastigotes might not occur in less severe clinical cases. In addition, comparative studies between paired clinically-lesioned and normal-looking skin samples from dogs with different disease severity are lacking. The objective of this study was to compare histological and parasitological findings by Leishmania immunohistochemistry (IHC) and quantitative PCR (qPCR) on paired clinically-lesioned and normal-looking skin biopsies from 25 dogs with different clinical stages of leishmaniosis, 11 with stage I-mild disease (papular dermatitis) and 14 with stage II-III (ulcerative or exfoliative dermatitis)...

BACKGROUND: Infection and clinical disease associated with Leishmania major and Leishmania tropica, two common agents of human cutaneous leishmaniosis, have rarely been reported in dogs. This study describes dogs infected with these Leishmania spp. prevalent in the Middle East and North Africa, and compares the serological response of dogs infected with Leishmania infantum, L. major or L. tropica to whole promastigote antigen enzyme-linked immunosorbent assay (ELISA) of each species and to rK39 dipstick...

BACKGROUND: Anti-Leishmania antibodies are increasingly investigated in cats for epidemiological studies or for the diagnosis of clinical feline leishmaniosis. The immunofluorescent antibody test (IFAT), the enzyme-linked immunosorbent assay (ELISA) and western blot (WB) are the serological tests more frequently used. The aim of the present study was to assess diagnostic performance of IFAT, ELISA and WB to detect anti-L. infantum antibodies in feline serum samples obtained from endemic (n = 76) and non-endemic (n = 64) areas and from cats affected by feline leishmaniosis (n = 21) by a Bayesian approach without a gold standard...

BACKGROUND: Phlebotomine sand fly-borne diseases such as leishmanioses and phleboviruses are emerging threats to animal and public health. Canine leishmaniosis caused by Leishmania infantum is an endemic zoonosis in Portugal. Antibodies to Toscana virus (TOSV) and sand fly fever Sicilian virus (SFSV) were also reported in dogs from the south of the country. The aim of this work was to evaluate a possible association between exposure to L. infantum, TOSV and SFSV in sheltered dogs from the south of Portugal...

Transmission of canine leishmaniosis (CanL) is described in three consecutive generations of female Boxers living in a non-endemic environment in the Czech Republic. Infection of the first generation female likely occurred during a breeding visit to Italy and the dog died with typical clinical signs of the disease but without definitive laboratory diagnosis. The second and third generation offsprings never left the Czech Republic, suffered from clinical CanL confirmed by polymerase chain reaction and serology, and were apparently infected by transplacental transmission...

Hemophagocytic lymphohistiocytosis (HLH) is a rare and severe syndrome usually associated with a cytotoxicity deficiency, which leads to an excess of immune response driven by activated macrophages and cytotoxic T cells. In children, HLH can be genetic, as part of a familial lymphohistiocytosis, or secondary: the most frequent causes are systemic-onset juvenile idiopathic arthritis, hematological malignancies, and severe infections, especially with Ebstein-Barr virus or leishmaniosis. We report on the case of a 3-year-old girl with no past medical history, who presented inaugural Pseudomonas aeruginosa maxillary osteitis, with secondary HLH...

BACKGROUND: Identification of Leishmania infantum-infected dogs is crucial for control of canine leishmaniosis. In particular, in areas where access to specialized laboratories is limited, the availability of reliable and rapid in-clinic serologic tests may support immediate diagnosis in suspected cases and permit detection of asymptomatic canine carriers of L infantum infection. OBJECTIVE: The purpose of the study was to validate the immunochromatographic test (ICT) Anigen Rapid Leishmania Ab Test kit for detection of L infantum antibodies in naturally exposed dogs in comparison with the immunofluorescence antibody test (IFAT)...

Travel to developing countries is associated with possibility to acquire different, also parasitic, diseases which have become a diagnostic and therapeutic problem. The ENT specialist is one of the medical officers who may make initial contact with a patient with a suspected parasitic disease. One of them is leishmaniosis: a parasitic disease classified as Neglected Tropical Diseases (NTD), which occurs in the tropics, subtropics and southern Europe. While asymptomatic invasion is observed in some cases, three forms of symptomatic leishmaniosis can be distinguished: cutaneous leishmaniosis (CL), visceral leishmaniosis (VL), and mucosal leishmaniosis (ML)...

Knowledge of how canine leishmaniosis (CanL) is being managed clinically and its epidemiology is very important, since dogs are the main reservoir of human leishmaniosis. This study reports the results obtained through a questionnaire-based survey of veterinary practitioners in Girona province, a recognised, but non-documented endemic area in north-eastern Spain. The primary objective was to obtain data on the clinical management of CanL, focusing particularly on new preventive methods and therapeutic tools...

Monitoring of selected serum acute phase proteins like C-reactive protein (CRP) and ferritin could be useful for evaluation of the response to treatment in both naturally-occurring and experimentally-induced leishmaniosis. However studies until date have only been focused on dogs with an adequate response to the treatment and there is a lack of knowledge about the possible associations between the CRP and ferritin and the different clinicopathological conditions that can appear after treatment. Thus, the main objective of this retrospective study was to evaluate and compare the serum concentration of CRP and ferritin between three possible situations that dogs which undergo leishmaniosis treatment could have: responsive with total recovery, responsive with only clinical recovery but persistent abnormalities in biochemical analytes, and unresponsive with clinical and biochemical changes...

The aims of this study were: the identification of proteins differentially represented in the serum proteome of dogs with leishmaniosis after treatment and the verification of one selected protein as a possible biomarker for treatment monitoring. Serum samples from five dogs with leishmaniosis, before and after treatment were pooled into two groups and analysed using 2-dimensional electrophoresis followed by mass spectrometry analysis (MS). The MS analysis allowed the identification of 8 proteins differently expressed...

Leishmaniasis is a disease caused by Leishmania and spread by the bite of certain types of sandflies. Leishmaniasis affects as many as 12 million people worldwide, with 2 million new cases each year. Leishmania infection, and Leishmaniasis, following occupational exposure has been also reported. Three forms of Leishmaniasis are known: a- Cutaneous Leishmaniasis (CL); b-Mucocutaneous Leishmaniasis; c- Visceral Leishmaniasis (VL). The visceral form of Leishmaniasis has an estimated incidence of 500,000 new cases...

BACKGROUND: The current chemotherapy for cutaneous leishmaniosis (CL) has a series of drug limitations such as toxic side effects, long duration, high costs and drug resistance, which requires the development of new drugs or effective alternatives to the CL treatment. Essential oils (EOs) are complex mixtures of secondary metabolites from various plants. It has been shown that several EOs, or their constituents, have inhibitory activity against protozoa. Thus, this study aims to evaluate the biological activity of different essential oils (EOs) on Leishmania (L...
