Antifungal activities of vineyard-habitat wild yeast for grape gray-mold disease and its effects on spontaneous winemaking.

Microorganisms, including native yeasts, are abundant in vineyard fields. Herein, we studied the possibility of using vineyard-derived wild yeast as a microbial pesticide against Botrytis cinerea, a pathogen that causes grape gray mold disease, to boost the initial alcohol production of spontaneously fermented wine. We identified the Saccharomyces cerevisiae strain KONDO170908, which showed the most effective antifungal activity in an ex vivo yeast dripping experiment on grape berries.

Decreased Immunoreactivity of Hepatitis E Virus Antigen Following Treatment with Sakhalin Spruce (Picea glehnii) Essential Oil.

The hepatitis E virus (HEV) causes a common infectious disease that infects pigs, wild boars, deer, and humans. In most cases, humans are infected by eating raw meat. Some essential oils have been reported to exhibit antiviral activities.

[A CASE OF PULMONARY FLARE-UP TUBERCULOSIS WITH AN ESOPHAGO-BRONCHIAL FISTULAS AFTER CHEMORADIOTHERAPY FOR ESOPHAGEAL CANCER].

We present a case of a 59-year-old man with pulmonary tuberculosis and esophago-bronchial fistulas after chemoradiotherapy (CRT) for esophageal cancer. A lung nodule was detected in the right upper lobe and diagnosed as an inactive old inflammatory tumor by several examinations, including bronchoscopy. He was admitted to our hospital because of dysphagia 3 months later.

Bacterial communities in fish sauce mash using culture-dependent and -independent methods.

In fish sauce production, microorganisms are associated with the fermentation process; however, the sequential changes in the bacterial communities have never been examined throughout the period of fermentation. In this study, we determined the bacterial floras in a fish sauce mash over 8 months, using three different culture media and 16S rRNA gene clone library analysis. During the first 4 weeks, viable counts of non-halophilic and halophilic bacteria decreased and were dominated by Staphylococcus species.
