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.

Experimental canine leishmaniasis: clinical, parasitological and serological follow-up

  • Autores: Campino L, Cristóvão J, Maia C, Nunes M
  • Ano de Publicação: 2010
  • Journal: Acta Tropica
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Experimental+canine+leishmaniasis%3A+clinical%2C+parasitological+and+serological+follow-up

Canine leishmaniasis (CanL) caused by Leishmania infantum is transmitted by the bite of phlebotomine sand flies and affects millions of dogs in Europe, Asia, North Africa and South America. Canis familiaris is the major host for these parasites, and the main reservoir for human visceral infection. The development of effective molecules for therapy and immunoprophylaxis, […]

Feline Leishmania infection in a canine leishmaniasis endemic region, Portugal

  • Autores: Campino L, Cristóvão J, Gomes J, Maia C, Martins A, Nunes M, Rebêlo E
  • Ano de Publicação: 2010
  • Journal: Veterinary Parasitology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Feline+Leishmania+infection+in+a+canine+leishmaniasis+endemic+region%2C+Portugal

Canine leishmaniasis (CanL) caused by Leishmania infantum is a serious zoonotic public health and veterinary problem in the Mediterranean basin. Leishmania infection in domestic cats (Felis catus domesticus) has been reported in several countries where this zoonosis is endemic, such as Portugal, Spain, Italy, France, Greece, Israel, Palestine and Brazil. The aim of this study […]

Molecular Identification of Borrelia miyamotoi in Ixodes ricinus from Portugal

  • Autores: Campino L, Carreira T, Faria S, Lopes N, Maia C, Nunes M, Parreira R, Sousa C, Vieira ML
  • Ano de Publicação: 2015
  • Journal: Vector-Borne and Zoonotic Diseases
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/26273814

Borrelia miyamotoi, a relapsing fever spirochete, has been found recently in Ixodes ricinus ticks; however, little is known about its spatial distribution and potential local impact on human health.

Bacterial and protozoal agents of feline vector-borne diseases in domestic and stray cats from southern Portugal

  • Autores: Bastos F, Campino L, Cardoso L, Coimbra M, Maia C, Martins A, Nunes M, Pinto P, Ramos C, Vieira ML
  • Ano de Publicação: 2014
  • Journal: Parasites & Vectors
  • Link: http://www.parasitesandvectors.com/content/7/1/115

Feline vector-borne diseases (FVBD) have emerged in recent years, showing a wider geographic distribution and increased global prevalence. In addition to their veterinary importance, domestic cats play a central role in the transmission cycles of some FVBD agents by acting as reservoirs and sentinels, a circumstance that requires a One Health approach. The aim of the present work was to molecularly detect feline vector-borne bacteria and protozoa with veterinary and zoonotic importance, and to assess associated risk factors in cats from southern Portugal.

Molecular detection of bacterial and parasitic pathogens in hard ticks from Portugal

  • Autores: Campino L, Cardoso L, Ferreira A, Maia C, Nunes M, Vieira ML
  • Ano de Publicação: 2014
  • Journal: Ticks and Tick-Borne Diseases
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24745731

Ticks are important vector arthropods of human and animal pathogens. As information about agents of disease circulating in vectors in Portugal is limited, the aim of the present study was to detect bacteria and parasites with veterinary and zoonotic importance in ticks collected from dogs, cats, and field vegetation. A total of 925 ticks, comprising 888 (96.0%) adults, 8 (0.9%) nymphs, and 29 (3.1%) larvae, were collected in 4 geographic areas (districts) of Portugal.

First detection of Borrelia burgdorferi sensu lato DNA in Serum of the Wild Boar (Sus scrofa) in Northern Portugal by Nested-PCR

  • Autores: Cabral JA, Carreira T, Coelho C, Faria AS, Nunes M, Paiva-Cardoso MN, Vale-Gonçalves HM, Veloso O, Vieira ML, Vieira-Pinto M
  • Ano de Publicação: 2014
  • Journal: Ecohealth
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25231138

Lyme borreliosis is the most common tick-borne zoonosis in the northern hemisphere. Several vertebrates are crucial in the epidemiological cycle of Borrelia burgdorferi sensu lato, but the role of wild boar as a reservoir is still unknown. Sera were collected from 90 wild boars shot in the Trás-os-Montes region, Northern Portugal (hunting season 2011/2012).

Genetic diversity evaluation on Portuguese Leishmania infantum strains by multilocus microsatellite typing

  • Autores: Campino L, Cardoso L, Cortes S, Kuhls K, Lopes C, Marcos M, Mauricio IL, Nunes M, Schoenian G
  • Ano de Publicação: 2014
  • Journal: Infection Genetics and Evolution
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24815728

Leishmania infantum is the main etiological agent of zoonotic visceral leishmaniasis in the Mediterranean region, including Portugal, but, given its low isoenzyme diversity in this country, the population structure is poorly known. A set of 14 polymorphic microsatellite markers was studied on 136 Portuguese Leishmania strains isolated from different hosts, geographic regions and different clinical forms. A total of 108 different genotypes were found, which is a degree of genetic diversity comparable to other regions, even within zymodeme MON-1.
