Exploring resistance pathways for first-generation NS3/4A protease inhibitors boceprevir and telaprevir using Bayesian network learning

  • Authors: Ceccherini-Silberstein F, Cento V, Cuypers L, Di Maio VC, Libin P, Lunar MM, Nevens F, Nowé A, Poljak M, Schrooten Y, Theys K, Van Laethem K, Vandamme AM

Resistance-associated variants (RAVs) have been shown to influence treatment response to direct-acting antivirals (DAAs) and first generation NS3/4A protease inhibitors (PIs) in particular. Interpretation of hepatitis C virus (HCV) genotypic drug resistance remains a challenge, especially in patients who previously failed DAA therapy and need to be retreated with a second DAA based regimen. Bayesian […]

Molecular identification of Borrelia genus in questing hard ticks from Portugal: Phylogenetic characterization of two novel Relapsing Fever-like Borrelia sp.

  • Authors: Fingerle V, Lopes N, Maia C, Nunes M, Parreira R, Vieira ML
  • Publication Year: 2016
  • Journal: Infection Genetics and Evolution
  • Link: https://www.ncbi.nlm.nih.gov/pubmed/26976475

Molecular identification of Borrelia genus Several studies reported pathogenic species of Borrelia related to those that cause Tick-borne Relapsing Fever (RF). However, this studies unexpectedly suggested their transmission by hard ticks rather than by soft ticks. This study aimed to update the presence of B. burgdorferi s.l. species in ticks from several districts of Portugal, […]

Population diversity of Theileria annulata in Portugal

  • Authors: Amaro A, Gomes J, Inácio J, Pereira da Fonseca I, Pinto J, Salgueiro P, Santos-Gomes G, Shiels B, Tait A, Weir W

The tick-borne protozoan parasite Theileria annulata causes tropical theileriosis, a severe disease of cattle that occurs across the Mediterranean littoral, the Middle East and Southern Asia. In the Mediterranean region, the disease has long been perceived as being a constraint to livestock production in North Africa and Turkey but was believed to have minimal impact […]

Genetic diversity and population structure of Plasmodium falciparum over space and time in an African archipelago

  • Authors: Figueiredo RC, Pinto J, Salgueiro P, Vicente JL

The archipelago of São Tomé and Principe (STP), West Africa, has suffered the heavy burden of malaria since the 16th century. Until the last decade, when after a successful control program STP has become a low transmission country and one of the few nations with decreases of more than 90% in malaria admission and death […]

HCV1b genome evolution under selective pressure of the cyclophilin inhibitor alisporivir during the DEB-025-HCV-203 phase II clinical trial

  • Authors: Crabbe R, Cuypers L, Kerremans L, Libin P, Snoeck J, Van Dooren S, Vandamme AM, Vuagniaux G

Major advances have revolutionized the HCV antiviral treatment field, with interferon-free combinations of direct-acting antivirals (DAAs) resulting into success rates of >90% for all HCV genotypes. Nevertheless, viral eradication at a global level stills remains challenging, stimulating the continued search for new affordable pan-genotypic drugs. To overcome selection of drug resistant variants, targeting host proteins […]
