Phylogenetic insights on Leishmania detected in cats as revealed by nucleotide sequence analysis of multiple genetic markers

  • Autores: Pereira A, Parreira R, Cristovao JM, Castelli G, Bruno F, Vitale F, Campino L, Maia C
  • Ano de Publicação: 2020
  • Journal: Infection Genetics and Evolution
  • Link: https://www.sciencedirect.com/science/article/pii/S1567134819302953?via%3Dihub

Cats have been found infected by the same Leishmania species that also infect dogs and humans in both the New and Old Worlds, and their role as additional reservoir hosts of L. infantum has been previously suggested. Currently, the genetic diversity of Leishmania spp. detected in cats is poorly understood. In this cross-sectional study, the […]

Vaccination against canine leishmaniasis in Brazil

Prevention of canine Leishmania infantum infection is critical to management of visceral leishmaniasis in people living in endemic areas of Brazil. A bill (PL 1738/11), currently under consideration, proposes to establish a national vaccination policy against canine leishmaniasis in Brazil. However, there is no solid scientific evidence supporting the idea that this could reduce transmission […]

Experimental Infection of Dogs with Toscana Virus and Sandfly Fever Sicilian Virus to Determine Their Potential as Possible Vertebrate Hosts

  • Autores: Muñoz C, Ayhan N, Ortuño M, Ortiz J, Gould E, Maia C, Berriatua E, Charrel R
  • Ano de Publicação: 2020
  • Journal: Microorganisms
  • Link: https://www.mdpi.com/2076-2607/8/4/596

The sandfly-borne Toscana phlebovirus (TOSV), a close relative of the sandfly fever Sicilian phlebovirus (SFSV), is one of the most common causes of acute meningitis or meningoencephalitis in humans in the Mediterranean Basin. However, most of human phlebovirus infections in endemic areas either are asymptomatic or cause mild influenza-like illness. To date, a vertebrate reservoir […]

Identification of trypanosomatids and blood feeding preferences of phlebotomine sand fly species common in Sicily, Southern Italy

  • Autores: Abbate JM, Maia C, Pereira A, Arfuso F, Gaglio G, Rizzo M, Caracappa G, Marino G, Pollmeier M, Giannetto S, Brianti E

In this study, the presence of Leishmania DNA and blood feeding sources in phlebotomine sand fly species commonly present in Sicily were investigated. A total of 1,866 female sand flies including 176 blood fed specimens were sampled over two seasons in five selected sites in Sicily (southern Italy). Sergentomyia minuta (n = 1,264) and Phlebotomus […]

In vitro and in vivo behaviour of sympatric Leishmania (V.) braziliensis, L. (V.) peruviana and their hybrids.

Leishmania (Viannia) braziliensis is the main cause of highly disfiguring mucocutaneous leishmaniasis (MCL) in South America. The related species L. (V.) peruviana has only been identified in simple cutaneous lesions (CL). Hybrids between L. braziliensis and L. peruviana have been reported although genetic exchange in Leishmania is considered to be rare. Here we compared growth in vitro, adaptive capacity under thermal and oxidative stress and behaviour in a hamster model, of L. braziliensis, L. peruviana, and their putative hybrids. At 24°C, the optimal temperature for in vitro growth, L. braziliensis had the highest growth rate.

Cytokine and Phenotypic Cell Profiles of Leishmania infantum Infection in the Dog.

Leishmaniasis has reemerged in recent years showing a wider geographic distribution and increased global incidence of human and canine disease than previously known. Dogs are the main domestic/peridomestic reservoir hosts of zoonotic visceral leishmaniasis caused by Leishmania infantum.

EPIDEMIOLOGY OF LEISHMANIASES IN PORTUGAL

  • Ano de Publicação: 2010

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.

In vitro drug susceptibility of Leishmania infantum isolated from humans and dogs

  • Autores: Campino L, Henriques S, Maia C, Marques M, Nunes M, Rolão N
  • Ano de Publicação: 2013
  • Journal: Experimental Parasitology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/23747751

Visceral leishmaniasis (VL) caused by parasites of Leishmania donovani complex is a severe human disease which often leads to death if left untreated. Domestic dogs are the main reservoir hosts for zoonotic human visceral infection caused by Leishmania infantum. In the absence of effective human and dog vaccines, the only feasible way to treat and control leishmaniasis is through the use of suitable medications.

Antimony resistance and environment: Elusive links to explore during Leishmania life cycle.

  • Autores: Ait-Oudhia K, Maia C, Sereno D
  • Ano de Publicação: 2012
  • Journal: International Journal for Parasitology: Drugs and Drug Resistance
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Antimony+resistance+and+environment%3A+elusive+links+to+explore+during+Leishmania+life+cycle.

Leishmania drug resistance and particularly antimony resistance still continues to emerge in different part of the world. Because visceral and cutaneous leishmaniasis are transmitted in foci with zoonotic or anthroponotic life-cycles, the link between chemotherapeutic resistance and the selection for drug resistance, through drug consumption, cannot be as obvious for all forms of leishmaniasis.

Leishmania infection and host-blood feeding preferences of phlebotomine sandflies and canine leishmaniasis in an endemic European area, the Algarve Region in Portugal

  • Autores: Afonso MO, Campino L, Cristovao JM, Dionísio L, Maia C, Neto L
  • Ano de Publicação: 2013
  • Journal: Memorias do Instituto Oswaldo Cruz
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/23827997

The Algarve Region (AR) in southern Portugal, which is an international tourist destination, has been considered an endemic region of zoonotic leishmaniasis caused by Leishmania infantum since the 1980s. In the present study, phlebotomine and canine surveys were conducted to identify sandfly blood meal sources and to update the occurrence of Leishmania infection in vectors and dogs.
