Opisthorchis felineus, an emerging infection in Italy and its implication for the European Union.

The liver fluke Opisthorchis felineus is one of the few zoonotic trematodes that circulates in the European Union (EU). It is transmitted from freshwater snails to fish and then to fish-eating mammals, including humans, in which it causes opisthorchiasis. In the 20th century, the majority of infections in humans have been reported in Eastern Europe (e.

Cryptic and asymptomatic Opisthorchis felineus infections.

We describe the diagnostic difficulties experienced during an opisthorchiasis outbreak. Of 31 infected individuals, 61.3% were asymptomatic, and in the 12 symptomatic individuals, the duration of non-pathognomonic symptoms was shorter than 4 weeks.

Human illnesses caused by Opisthorchis felineus flukes, Italy.

We report 2 outbreaks of Opisthorchis felineus infection caused by the consumption of tench filets (Tinca tinca) from a lake in Italy. Of the 22 infected persons, 10 (45.4%) were asymptomatic.

Adefovir and lamivudine in combination compared with adefovir monotherapy in HBeAg-negative adults with chronic hepatitis B virus infection and clinical or virologic resistance to lamivudine: a retrospective, multicenter, nonrandomized, open-label study.

Objectives: The aim of this study was to assess the therapeutic effectiveness of adefovir dipivoxil (ADV), administered in combination with lamivudine (LAM) or as monotherapy, and the rate of resistance to ADV, in hepatitis B e antigen (HBeAg)-negative adult patients with chronic hepatitis B virus (HBV) infection and clinical or virologic resistance to LAM. Furthermore, we evaluated in these selected patients the clinical co-variates associated with a sustained virologic response.

Methods: Data from adult outpatients aged >18 years with chronic HBV infection and clinical or virologic resistance to LAM were used in this retrospective, multicenter, nonrandomized, open-label study.

Characterization of denatured proteins by hydrophobic interaction chromatography: a preliminary study.

In this preliminary study hydrophobic interaction chromatography (HIC) is proposed as a good tool in order to detect conformational changes induced by chemical denaturants in two globular proteins, cytochrome C (Cyt C) and myoglobin (MYO). Alterations in protein structure were manifested chromatographically by reproducible changes in peak heights, retention time, and appearance of multiple peaks. The HIC behavior of the two model proteins denatured by guanidinium thyocyanate (GdmSCN) was investigated, keeping constant various concentrations of urea in the mobile phase in a TSK-Gel Phenyl-5PW column (TosoBiosep).
