Antiplasmodial activity of tick defensins in a mouse model of malaria

  • Authors: Couto J, Tonk M, Ferrolho J, Antunes S, Vilcinskas A, de la Fuente J, Domingos A, Cabezas-Cruz A
  • Publication Year: 2018
  • Journal: Ticks and Tick-Borne Diseases

Malaria is a mosquito-borne disease affecting millions of people mainly in Sub-Saharan Africa, Asia and some South American countries. Drug resistance to first-line antimalarial drugs (e.g. chloroquine, sulfadoxine–pyrimethamine and artemisinin) is a major constrain in malaria control. Antimicrobial peptides (AMPs) have shown promising results in controlling Plasmodium spp. parasitemia in in vitro and in vivo […]

The role of regulatory CD4+CD25+ T cell subset in host homeostasis during protozoan infection

  • Authors: Domingos A, Domingues N, Ferrolho J, Santos-Gomes G
  • Publication Year: 2015
  • Journal: International Trends in Immunity
  • Link: https://www.researchgate.net/publication/275021971_The_Role_of_Regulatory_CD4CD25_T_Cell_Subset_in_Host_Homeostasis_during_Protozoan_Infection_An_Overview%20

Human diseases caused by protozoan parasites are renowned for their high rates of morbidity and mortality worldwide. Some examples include African trypanosomiasis or sleeping sickness, American trypanosomiasis or Chagas disease, leishmaniases, malaria and babesiosis. These infections tend to follow a chronic rather than an acute course with lifelong persistence of parasites. Regulatory T cells (Treg), in […]

Rotation of the external genitalia in male Phlebotomine sand flies (Diptera, Psychodidae) in laboratory conditions and in captured specimens in Algarve, Portugal

  • Authors: Afonso MO, Alves-Pires C, Campino L, Cristóvão JM, Ferrolho J, Gomes J, Maia C
  • Publication Year: 2015
  • Journal: Acta Tropica

Protozoal parasites are the causative agents of many insect-borne infectious diseases worldwide with impact on human and animal health. Leishmaniasis is caused by Leishmania spp. and transmitted by female Phlebotomine sand flies. In Portugal, two species of Phlebotomus (Larroussius), namely Phlebotomus perniciosus and Phlebotomus ariasi are the proven vectors of Leishmania infantum. Phlebotomine females and […]

Growth of Ehrlichia canis, the causative agent of canine monocytic ehrlichiosis, in vector and non-vector ixodid tick cell lines

  • Authors: Bell-Sakyi L, Ferrolho J, Hawes P, Simpson J, Zweygarth E
  • Publication Year: 2016
  • Journal: Ticks and Tick-Borne Diseases
  • Link: https://www.sciencedirect.com/science/article/pii/S1877959X16300127?via%3Dihub

Canine monocytic ehrlichiosis is caused by Ehrlichia canis, a small gram-negative coccoid bacterium that infects circulating monocytes. The disease is transmitted by the brown dog tick Rhipicephalus sanguineus s.l. and is acknowledged as an important infectious disease of dogs and other members of the family Canidae worldwide. E. canis is routinely cultured in vitro in […]

Cattle Specific Immune Mechanisms used against the Protozoan Theileria annulata

  • Authors: Campino L, Domingos A, Ferrolho J
  • Publication Year: 2016
  • Journal: International Trends in Immunity
  • Link: http://researchpub.org/journal/iti/number/vol4-no2/vol4-no2-2.pdf

Theileria annulata, the causative agent of tropical theileriosis, is an intracellular protozoan parasite transmitted by ticks of the genus Hyalomma. This tick-borne disease (TBD) exerts a high impact on livestock production in many developing tropical and subtropical countries. With an intricate life cycle and wide distribution around the world, many advances were made to restrict […]
