Human microbiome, June 13

Sjögren’s disease, diabetes, and Clostridium difficile infection. And the importance of a good title.

Oral microbiome

ScienceCodexSjögren’s Syndrome significantly increases risk of heart attack – Science Codex

“A new study presented today at the European League Against Rheumatism Annual Congress (EULAR 2014) showed a significantly increased risk of heart attack in patients with Sjögren’s syndrome (SjS), particularly in the first year following diagnosis.”

Gut microbiome

DiabetologiaStudy shows gut microbe composition different in young children with and without type 1 diabetes [zipped PDF]- Marcus de Goffau and Hermie Hansen – Diabetologia

and in the press:

diabetesStudy shows gut microbe composition different in young children with and without type 1 diabetes – Medical Xpress

“New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) shows that children diagnosed with type 1 diabetes have a less balanced composition of gut bacteria compared with children of the same age without diabetes. “

KefirStaggered and tapered antibiotic withdrawal (STAW) with administration of Kefir for recurrent Clostridium difficile infection – Johan S. Bakken – Clinical Infectious Diseases

“Daily administration of the probiotic Kefir given in combination with a staggered and tapered antibiotic withdrawal regimen may resolve recurrent Clostridium difficile infection as effectively as fecal microbiota transplantation (FMT).”

Animal models of human microbiome and disease

I’m trying hard to wrap my brain around this title:
AACGastrointestinal Colonization With a Cephalosporinase-Producing Bacteroides Species Preserves Colonization Resistance Against Vancomycin-Resistant Enterococcus and Clostridium difficile in Cephalosporin-Treated Mice – Usha Stiefel – Antimicrobial Agents and Chemotherapy

“Stool concentrations of VRE and ceftriaxone were measured, cecal levels of C. difficile 24 hours after incubation were quantified, and denaturing gradient gel electrophoresis (DGGE) of microbial 16S rRNA genes was performed to evaluate antibiotic effect on the microbiota. “

In the press, much better title:

Good bacteria armed with antibiotic resistance protect gut microbiome – Science Codex

“The novel aspect of the research is that the enzyme produced by these bacteria, beta-lactamase, is a major cause of antibiotic resistance, says first author, Usha Stiefel. Interestingly, the enzyme is not only protecting the bacteria that produce it but also the rest of the bacteria making up the intestinal microbiome.”

“Bacterial vaginosis is a common vaginal infection characterized by changes in the vaginal microbiota. The objective of this work was to evaluate the colonization ability and curative effect of Lactobacillus fermentum L23 after vaginal administration in female BALB/c mice infected with Gardnerella vaginalis. “
