Molecular evolution and population genetics of a Gram-negative binding protein gene in the malaria vector Anopheles gambiae (sensu lato)

  • Authors: Arez AP, Charlwood JD, Lopes AS, Mendes C, Pinto J, Salgueiro P, Silveira H
  • Publication Year: 2016
  • Journal: Parasites & Vectors

Background Clarifying the role of the innate immune system of the malaria vector Anopheles gambiae is a potential way to block the development of the Plasmodium parasites. Pathogen recognition is the first step of innate immune response, where pattern recognition proteins like GNBPs play a central role. Results We analysed 70 sequences of the protein coding gene GNBPB2 from two species, Anopheles […]

Tongue nodules in canine leishmaniosis–a case report.

  • Authors: Albuquerque C, Campino L, Cardoso L, Dias I, Machado J, Pires MA, Requicha J, Sargo T, Viegas C
  • Journal: Parasites & Vectors
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/22704596

BACKGROUND:
Canine leishmaniosis (CanL) caused by Leishmania infantum is an endemic zoonosis in southern European countries. Infected dogs can present rare or atypical forms of the disease and diagnosis can be challenging. The present report describes a case of tongue nodules in a 3-year-old neutered female Labrador Retriever dog with leishmaniosis.

Inoculation of Triatoma Virus (Dicistroviridae: Cripavirus) elicits a non-infective immune response in mice

  • Authors: Agirre J, Guérin DMA, Marti GA, Querido JFB, Silva MS
  • Journal: Parasites & Vectors
  • Link: http://www.parasitesandvectors.com/content/6/1/66

Dicistroviridae is a new family of small, non-enveloped, +ssRNA viruses pathogenic to both beneficial arthropods and insect pests. Little is known about the dicistrovirus replication mechanism or gene function, and any knowledge on these subjects comes mainly from comparisons with mammalian viruses from the Picornaviridae family.

Feeding patterns of molestus and pipiens forms of Culex pipiens (Diptera: Culicidae) in a region of high hybridization

  • Authors: Almeida AP, Arez E, Calderón I, Donnelly MJ, Gomes B, Pinho L, Pinto J, Sousa CA, Vicente JL
  • Journal: Parasites & Vectors
  • Link: http://www.parasitesandvectors.com/content/6/1/93

Two biological forms of the mosquito Culex pipiens s.s., denoted pipiens and molestus, display behavioural differences that may affect their role as vectors of arboviruses. In this study, the feeding patterns of molestus and pipiens forms were investigated in Comporta (Portugal), where high levels of inter-form admixture have been recorded.
