The influence of probiotic bacteria and human gut microorganisms causing opportunistic infections on Blastocystis ST3

ConclusionsThis study has shown the potential of usingL. rhamnosus andL. lactis, as well asE. faecium as a prophylactic treatment againstBlastocystis colonization or as an additional treatment regimen in combination with standard drugs.

Authors: Santacroce L, Charitos IA, Bottalico L Abstract Introduction: Probiotics are living, non-pathogenic microorganisms (bacteria) that enter through diet in the human body, live during their passage through the gastrointestinal (GI) tract and are beneficial to health. They have become popular in recent years as a way of improving human health through nutrition. This review aims to discuss the efficacy of probiotics for the supportive therapy of certain clinical conditions, especially infectious diseases, as reported in a number of studies, even though some concerns about their safety still remain. Areas covere...

The goal of our current study is to understand the growth inhibitory mechanism of biosynthesized CdS nanoparticles on E. coli bacteria.Main methodsCharacterization of Aspergillus foetidus mediated CdS nanoparticles has been confirmed by Zeta potential, AFM and HRTEM analyses. Furthermore, we investigated the contribution of reactive ...

We present the first documented case of candida colitis caused by Candida Glabrata in a 56-year-old man with a personal history of morbid obesity and bariatric surgery. The presenting symptoms were diarrhea, rectal bleeding and septic shock. Diagnosis was obtained by histological and microbiological study of the colonoscopy biopsies. Gastroenterologists should be aware of Candida as a cause of colonic infection. Fungal culture is the key to identify specific Candida species and lead to an appropriate antifungal therapy.

This study identified the processing conditions of these three nonthermal technologies for the pasteurization of strawberry juice based on equivalent inactivation of acid-adapted E. coli. From an industrial point of view, the established processing conditions are useful references for the development of novel berry juices. In addition to microbiological safety, this study on equivalent processing allows direct efficacy and quality comparisons of a given juice pasteurized by the three nonthermal technologies under consideration.

Publication date: Available online 19 July 2019Source: Food ControlAuthor(s): Elizabeth C. Buerman, Randy W. Worobo, Olga I. Padilla-ZakourAbstractHigh Pressure Processing (HPP) is a method used to extend shelf life of foods by subjecting products in their final packaging to extreme pressure. This leads to protein degradation in microbial cells, membrane degradation, and eventual cell death. Survival of spoilage organisms, especially spore-formers, has not been closely considered in regard to the effect of water activity (aw). The purpose of this study was to determine the effect of pH and aw on HPP apple juice to prevent ...

e;ez Grau Gema Jiménez Juan A. Marchal Houria Boulaiz Due to the high prevalence of cancer in recent years, it is necessary to develop new and more effective therapies that produce fewer side effects. Development of gene therapy for cancer based on the use of suicide genes that can damage the tumor cell, without requiring a prodrug for its lethal effect, is one of the recent foci of gene therapy strategies. We evaluated the cytotoxic impact of the LdrB toxin from Escherichia coli k12 as a possible tool for cancer gene therapy. For that, colorectal and breast cancer cells were transfected under the control ...

WilsonAbstractLawsonia intracellularis is an obligate intracellular microorganism and the causative agent of porcine proliferative enteropathy. Due to its obligate intracellular nature, characterization of antigens and proteins involved in host-pathogen interaction and immune recognition have been difficult to achieve using conventional microbiological techniques. In this work, we used 2-dimensional gel electrophoresis coupled with Western-immuno...

Authors: Herman A Abstract In recent years increased interest in the connection of intestinal microflora and the state of human health resulted in a great deal of research on the influence of intestinal microflora in particular on mental health, including works on affective functions of the central nervous system (CNS). Previous studies on animals have revealed the existence of a bi-directional communication system between the gastrointestinal microbiota and the central nervous system, the so-called .gut-brain axis' which modulates functioning of CNS through immunological, endocrine and neuronal mechanisms. Clinica...

The objective of this work is to evaluate the level of pollution of different drinking water sources consumed and its link with health in Pelengana commune, Mali. Samples of water were taken from various sources, namely, hand pumps, boreholes, dug wells, and shallow wells for physical, chemical, heavy metals, and bacteriological analyses, using American Public Health Association (APHA) Standard Techniques. Results revealed that the nitrate-nitrogen (NO3-N) values of the water samples from the different water sources had concentrations exceeding the United States Environmental Protection Agency's (US-EPA) regulation of 10 m...

In this study, the microbiological quality of water from mines and shallow wells was analyzed for human consumption. Genotypic and phenotypic characterization of DEC strains was performed. A total of 210 water samples was analyzed, of which 153 (72.9%) contained total coliforms and 96 (45.7%) E. coli. Of the E. coli isolates, 27 (28.1%) contained DEC genes. The DEC isolates included 48.1% Shiga toxin-producing E. coli (STEC), 29.6% enteroaggregative E. coli (EAEC), 14.9% enteropathogenic E. coli (EPEC), 3.7% enterotoxigenic E. coli (ETEC), and 3.7% enteroinvasive E. coli (EIEC). All the STECs had cytotoxic effects on Vero ...
