Infectivity of Chordodes nobilii larvae (Gordiida: Nematomorpha)

Rev. biol. trop; 65 (1), 2017
AbstractThe gordiids are freshwater representatives of the parasite phylum Nematomorpha that function as a link between aquatic and terrestrial ecosystems. In recent years, different ecotoxicologic studies have been made with the South-American gordiid species, Chordodes nobilii, that have demonstrated t...

Trypanosoma evansi (Kinetoplastida: Trypanosomatidae) in capybaras ( Hydrochoerus hydrochaeris ): prevalence, effect and sexual selection

Rev. biol. trop; 65 (1), 2017
AbstractParasites play a crucial role in the ecology of animals. They also appear to be important in mechanisms underlying sexual selection processes. In this article we study the prevalence, effect and potential role in sexual selection of the protozoon Trypanosoma evansi in capybaras, Hydrochoerus hydr...

Role of Candida species from HIV infected children in enamel caries lesions: an in vitro study

J. appl. oral sci; 25 (1), 2017
Abstract Objectives This study analyzed the capacity of Candida spp. from dental biofilm of HIV infected (HIV+) children to demineralize primary molar enamel in vitro by Transversal Microhardness (TMH), Polarized Light Microscopy (PLM) and the quantity of calcium ions (Ca2+) released from the enamel. ...

High Clinical Manifestation Rate in an Imported Outbreak of Hepatitis E Genotype 1 Infection in a German Group of Travellers Returning from India

Ann. hepatol; 16 (1), 2017
Abstract: Background. There are only few reports about travel-associated, imported tropical hepatitis E virus (HEV) genotype 1 infections within Western travellers. We describe the clinical course of a single outbreak of hepatitis E in a German travellers group returning from India and compare the resu...

Sofosbuvir and Daclatasvir in Mono-and HIV-coinfected Patients with Recurrent Hepatitis C After Liver Transplant

Ann. hepatol; 16 (1), 2017
Abstract: Background and aims. Pegylated interferon (Peg-INF) and ribavirin (RBV) based therapy is suboptimal and poorly tolerated. We evaluated the safety, tolerability and efficacy of a 24-week course of sofosbuvir plus daclatasvir without ribavirin for the treatment of hepatitis C virus (HCV) recurr...

Candida auris: emergence and epidemiology of a highly pathogenic yeast

Clin. biomed. res; 37 (3), 2017
Candida auris is a multidrug-resistant emerging yeast, which was responsible for healthcare-associated infection outbreaks, and was cataloged as a new species in 2009, after being isolated from a patient’s ear canal secretion in Japan. Since the notification of this first occurrence, numerous cases hav...

Effect of peracetic acid on biofilms formed by Listeria monocytogenes strains isolated from a Brazilian cheese processing plant

ABSTRACT This study aimed to investigate the effect of peracetic acid (PAA, 0.5%) on adherent cells of three strains of Listeria monocytogenes strains belonging to serotypes 4b and 1/2b that had been previously isolated from the environment of a Brazilian cheese plant. The assays were conducted using pol...

Different engagement of TLR2 and TLR4 in Porphyromonas gingivalis vs. ligature-induced periodontal bone loss

Abstract This study was conducted to investigate the roles of different Toll-like receptor (TLR) signaling in Porphyromonas gingivalis (P. gingivalis)-induced and ligature-induced experimental periodontal bone resorption in mice. Wild-type (WT), TLR2 knockout (KO), TLR4KO, and TLR2&4 KO mice with C57...
