Distribuição das espécies de crípticas de Candida em isolados de corrente sanguínea: identificação e perfil de sensibilidade antifúngica
Candidemias caracterizam um grave problema de saúde pública em todo mundo pela alta mortalidade dos casos, onde as espécies apresentam variação epidemiológica e na sensibilidade aos antifúngicos. Objetivou-se demonstrar a frequência de espécies de Candida, enfatizando as espécies crípticas e c...
Caracterização de mutações de resistência primária para as drogas antivirais de ação direta (DAA) para o vírus da Hepatite C
A Hepatite C constitui grave problema de saúde pública em todo mundo. Estima-se que, atualmente, em todo o mundo, cerca de 71 milhões de indivíduos estejam infectados por esse vírus. Na atualidade destacam-se os inibidores de polimerase (NS5B) e de N5A, como classes de medicamentos utilizados no tra...

Absence of mutations associated with resistance to benzimidazole in the beta-tubulin gene of Ascaris suum
Rev. Soc. Bras. Med. Trop; 53 (), 2020
Abstract INTRODUCTION: Benzimidazoles are commonly used for the control of veterinary nematodes. Resistance to benzimidazoles has been associated with three single nucleotide polymorphisms in the β-tubulin gene of common nematodes. However, these mutations are infrequent in the genus Ascaris spp. ...
In vitro-induction of metronidazole-resistant Giardia duodenalis is not associated with nucleotide alterations in the genes involved in pro-drug activation
Mem. Inst. Oswaldo Cruz; 115 (), 2020
Giardiasis is an infectious disease caused by Giardia duodenalis. The pro-drug metronidazole (MTZ) is the first-line treatment for giardiasis. Parasite's proteins as pyruvate:ferredoxin oxidoreductase (PFOR), ferredoxin (Fd), nitroreductase-1 (NR-1) and thioredoxin reductase (TrxR) participate in MTZ act...
Assessment of effectiveness of anakinra and canakinumab in patients with colchicine-resistant/unresponsive familial Mediterranean fever
Adv Rheumatol; 60 (), 2020
Abstract İntroduction: Familial Mediterranean fever (FMF) is a hereditary auto-inflammatory disease characterized by recurrent fever and serosal inflammation. Anti-interleukin-1 (Anti-IL-1) treatments are recommended in colchicine resistant and/or intolerant FMF patients. This study aims to evaluat...
Leishmania infantum induces high phagocytic capacity and intracellular nitric oxide production by human proinflammatory monocyte
Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND The mechanism of resistance to SbIII in Leishmania is complex, multifactorial and involves not only biochemical mechanisms, but also other elements, such as the immune system of the host. OBJECTIVES In this study, putative changes in the immunological profile of human monocytes infected wit...

Acquired antiretroviral drug resistance mutations upon treatment failure in HIV-1 infected pediatric patients in central Brazil
Rev. patol. trop; 49 (2), 2020
Antiretroviral drug-resistance mutations compromise the successful treatment of children and adolescents infected with human immunodeficiency virus type 1 (HIV-1). We describe the clinical, virological, and immunological follow-up of a cohort of children and adolescents perinatally infected w...
Is the efflux pump inhibitor Verapamil a potential booster for isoniazid against Mycobacterium tuberculosis?
Braz. J. Pharm. Sci. (Online); 56 (), 2020
The membrane-based efflux pump systems are recognized to have an important role in pathogenicity and drug resistance in Mycobacterium tuberculosis by the extrusion of toxic substrates and drugs from the inner bacillus. This study aimed to investigate the in vitro interaction of Verapamil (VP), an efflux ...
