3R initiatives for advanced biological safety tests

Earlier in the 19th century, the testing of biological safety in humans was a great challenge for pharmacists. Interestingly, even after being tested on animals, Koch's tuberculin was found to be unsafe for humans due to the patient's death. The first regulation was introduced ...

Microalgal applications in aquaculture and animal husbandry

If the world must attain the sustainable development goals in terms of food security, adequate sustainable sources of food and feed for both humans and animals, respectively, is indis- pensable. Aside from increasing production ...

Bacterial and fungal co-infection in a cohort of 333 patients hospitalized for Covid-19 (Coinfecovid study)

Background: Coinfections in COVID19 appear to worsen hospitalized patients prognosis. ...

An Integrated Evaluation of Mycoparasites from Organic Culture Soils as Biological Control Agents of Sclerotia of Sclerotinia Sclerotiorum in the Laboratory

Sclerotinia sclerotiorum is one of the most harmful phytopathogens in agriculture. They form sclerotia which render them resistant and persistent. Crop protection is necessary and mycoparasites are a friendly and efficient alternative to chemicals, when used as Biological Control Agents (BCAs). In this work, one hundred ninety nine candidate mycoparasites from soils of organic crops in Southwestern Greece were isolated by using ...

Investigation of Bacterial and Methanogen Community Composition and Diversity in full-scale Anaerobic Manure Digesters

Anaerobic digestion of biopolymers into methane is accomplished by complex microbial communities that remain poorly characterized. Their composition tends to vary, likely as a result of many factors such as substrate composition, operating parameters, and microbial succession. In order to gain further insight, we performed a comparative analysis of microbial ...

Prone Positioning in Influenza A Infection Following Lung Transplantation: A Case Report

Since 2009, influenza A infection represents a major concern for the scientific community; in the immediate postoperative of lung transplantation it is a rare event that may cause severe respiratory impairment. In case of refractory hypoxemia due to influenza infection, alternative strategies of oxygenation such as prone positioning have been efficiently used; however, no data exploring this issue were published. Herein, ...

Probiotic, Antimicrobial, Antioxidant and Sensory properties of Fermented donkey milk with Lactobacillus fermentum ME-3 and Lactobacillus acidophilus (ATCC 4356)

The aim of this study was to investigate the ability of the probiotic L.fermentum ME-3 and L.acidophilus (ATCC4356) to ferment pasteurized donkey's milk, keeping it in cold storage for 14 days and testing end products for antimicrobial, antioxidant activities and sensory properties. Fermented donkey milks had pH values of 4.5 - 4.6 just after fermentation...

Scanning Electron Microscopy

A scanning electron microscopy (SEM) is a type of electron microscope that uses a focused beam of high-energy electrons to produce images of a sample by creating a variety of signals at the surface of the sample. The signals are generated by the electron-sample interaction. These signals provide great information about the sample such as external morphology, ...

Gut Microbiota – Our Microbial Self

The gut microbiota (microbial symbionts) and microbiome (their genes, and consequently the corresponding expressed products) are part of us, interfering with our immunity, our capacity to metabolize certain molecules, influencing how we gain body weight and even our mood. The number of microbial cells and metabolites largely exceeds those of human body. ...

Study of Antibiotic Susceptibility Profile of Enterococcus Species

Enterococcus has emerged as one of the common cause of nosocomial infections. Their increasing resistance to commonly used antibiotics poses a great threat for treatment of enterococcal infections. Hence, the present study was undertaken to study the antibiotic susceptibility profile of Enterococcus species and to detect the incidence of Multidrug resistant Enterococcus species. ...

Yeasts Bioproducts Prospection from Different Brazilian Biomes

This research paper is a result of extensive work from a group of researchers participating in the BIOTA-FAPESP Program (FAPESP Research Program on Biodiversity Characterization, Conservation, Restoration and Sustainable Use), aimed at discovering, mapping and analyzing the diversity of the flora and fauna of the State of São Paulo, and also evaluating the possibilities ...

Molecular Affirmation of Aspergillus luchuensis a Niger Group Species as a Non-Ochratoxigenic Fungus

Amongst the various species of Aspergillus section Nigri; Aspergillus luchuensis, associated with food and beverage fermentation in East Asia, is evaluated by multiple researchers as non-ochratoxigenic based on the extrolite analysis. Beyond extrolite analysis, in the present study, A. luchuensis strain was analyzed by a rapid Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) technique. ...

Yeasts from Brazilian Biomes - The Reverse of the Coin

I read the recent research study by Ohara et al. [1] about yeasts bioproducts prospection from Brazilian biomes, including Atlantic Rain Forest, Savannah and transition areas. Diverse yeast isolations were obtained from samples of fruits, flowers and seeds (120), or soil (60), and were further prospected for lipase, biotin and riboflavin production [1]. The strain RP.J1308 was ...

Transcriptional Control of T-Cell Development: A Review

T-lymphocytes are types of lymphocytes that play a central role in cell-mediated immunity and consist of several subtypes with distinct functions. The thymus is a specialized primary lymphoid organ of the immune system, where T-lymphocytes mature. A naïve T-cell is a T-cell that has differentiated in the bone marrow, and successfully undergone the positive and negative process of central selection in the thymus. There are several developmental ...

Recent Update on MRSA

Methicillin-resistant S. aureus (MRSA) isolates are resistant to all available penicillins and other ß-lactam antimicrobial drugs. Staphylococcus aureus is the most commonly isolated human bacterial pathogen and is an important cause of skin and soft tissue infections (SSTIs), endovascular infections, pneumonia, septic arthritis, endocarditis, osteomyelitis, ...

Barley Distillers Dried Grains with Solubles (DDGS) as Feedstock for Production of Acetone, Butanol and Ethanol

Distillers dried grains with solubles (DDGS) represent important co-product from commercial yeast fermentations, including bioethanol, from grains. In view of the current expansion of the bioethanol fermentation process, with the concomitant increase in production of DDGS, alternative applications to their main current use as animal feed are being explored. ...
