Lifestyle switching -- Bacillus cereus is able to resist certain antibiotic therapies

(University of Veterinary Medicine -- Vienna) The pathogenic bacterium Bacillus cereus causes vomiting and diarrhoea as well as systemic and local infections. A team from the Vetmeduni Vienna has reported for the first time that B. cereus, following contact with certain antibiotics, can switch into a special slowed-down mode. The bacteria then form small colony variants (SVCs) that are difficult to diagnose and almost impossible to treat with certain antibiotics. This discovered mechanism may provide an alternative explanation for antibiotic resistance.

Authors: Večeřa Z, Krejčí T, Krajča J, Kanta M, Lipina R Abstract BACKGROUND: This work aims to determine how antibiotic therapy influences MR spectroscopic findings in patients undergoing treatment for pyogenic brain abscess. METHODS: This prospective, single center study included all patients who received treatment for brain abscesses at the Neurosurgery Department of University Hospital Ostrava between 2012-2017. Pre-operative MR imaging was carried out on all patients including diffusion-weighted imaging and in vivo single-voxel proton spectroscopy with intermediate echo time. The following facto...

Publication date: January 2020Source: Food Control, Volume 107Author(s): Irshaan Syed, Pratik Banerjee, Preetam SarkarAbstractApplication of plant-based essential oils as antimicrobial agents has received considerable attention. However, these antimicrobial compounds undergo quick depletion due to various factors such as volatile nature, low-water solubility, and interactions with lipophilic food components. Therefore, to retain the antimicrobial efficacy of such compounds, the combination with an oil-in-water based emulsion system as a carrier can be a viable option. The current work focuses on the development of geraniol...

AbstractTo investigate long-term health sequelae of cryptosporidiosis, with especial reference to post-infectious irritable bowel syndrome (PI-IBS). A prospective cohort study was carried out. All patients with laboratory-confirmed, genotyped cryptosporidiosis in Wales, UK, aged between 6  months and 45 years of age, over a 2-year period were contacted. Five hundred and five patients agreed to participate and were asked to complete questionnaires (paper or online) at baseline, 3 and 12 months after diagnosis. The presence/absence of IBS was established using the Rome III criteria for different age groups. Tw...

Of the 177 faecal samples, 27.1% were positive for Giardia cysts (immunofluorescence microscopy) and 55.4% for Cryptosporidium oocysts (phase-contrast microscopy). Positive samples were character...

CONCLUSIONS: Incorporation of chitosan hydrogel into honey can substantially enhance its antimicrobial and wound healing effects. Chitosan-hydrogel/honey (1:3) is an optimal wound dressing formulation with ample antimicrobial and healing properties. PMID: 31298661 [PubMed - as supplied by publisher]

Conclusions LTRS can be used to measure uptake and levels of berberine in single cells. High levels of berberine can enter spores of C. difficile and B. cereus soon after germination is initiated, thus inhibiting spore outgrowth and minimizing hazards posed by germinated spores.

Conclusion: This study provided some insight into the bacterial in vitro efficacies of plants traditionally used to treat diarrhoea by the people of Northern Maputaland. Very little connection was observed between frequency of use and efficacy. Plant combinations demonstrated favourable efficacy with mostly synergistic effects noted, lending some credibility to their use in combination.
