Microbial keystone taxa and metabolic signatures in centenarians regulate intestinal homeostasis during aging

iMeta, EarlyView.
Clostridium scindens and its metabolite indole‐3‐acetic acid (IAA) are identified as a keystone taxon and metabolic signature in centenarians. Clostridium scindens enhances microbial network stability and produces IAA via its own amidase (AMIE) and aldehyde dehydrogenase (ALDH), thus promoting intestinal homeostasis by activating the aryl hydrocarbon ...

Comparison of high-level gentamicin resistant (HLGR) Enterococcus faecium isolates from different continents.

, 1993
Eight clinical isolates of Enterococcus faecium highly resistant to gentamicin (MIC, > 1,000 mg/liter) from patients in six hospitals on three continents were investigated for evidence of spread of either a clone of high-level gentamicin-resistant (HLGR)

Cefdinir reprograms Gram‐positive bacteria to synergize with lysozyme against superbugs

mLife, EarlyView.
Abstract Multidrug‐resistant (MDR) bacteria pose a critical global health threat, urgently requiring solutions. Cefdinir, the highest‐selling third‐generation cephalosporin but one now facing clinical obsolescence due to escalating resistance, is conventionally classified as a nascent cell wall synthesis inhibitor.

Betulinic Acid Enema Alleviates Colitis by Targeting Vitamin D Receptor to Protect the Intestinal Mucosal Barrier and Modulate Mucosa‐Associated Microbiota

Phytotherapy Research, EarlyView.
ABSTRACT Ulcerative colitis (UC) is a chronic inflammatory disease of the colon with limited effectiveness and safety of current drug therapies. Betulinic acid (BA) is a naturally occurring pentacyclic triterpenoid present in traditional Chinese medicines used clinically as retention enemas for UC, but its direct effects and mechanisms remain unclear ...

Isolation of carbapenem‐resistant Pseudomonas aeruginosa and other Gram‐negative ESKAPE organisms from samples of raw‐meat diets for dogs in the UK

Veterinary Record, EarlyView.
Abstract Background Gram‐negative ESKAPE organisms are an emerging threat in veterinary medicine that also have zoonotic potential. However, little is known about the prevalence and risks of these organisms in pet food. We present the incidental finding of gram‐negative ESKAPE organisms within samples of raw meat diets for dogs in the United Kingdom ...

Induction of Probiotic Strain Enterococcus faecium EF1 on the Production of Cytokines, Superoxide Anion and Prostaglandin E2 in a Macrophage Cell Line [PDF]

Pakistan Veterinary Journal, 2012
Immunological effects of probiotic strain Enterococcus faecium EF1 was evaluated through the production of cytokines, superoxide anion (O2.-) and prostaglandin E2 (PGE2) in murine macrophage cell line RAW 264.7. In addition, the responses were contrasted
