Journal ArticleDOI

Compensatory evolution reveals functional interactions between ribosomal proteins S12, L14 and L19.

TL;DR: A novel functional role for the 50 S ribosomal protein L19 during protein synthesis is revealed, supporting published structural data suggesting that the interaction of L14 and L19 with 16 S rRNA could influence function of the 30 S subunit.
Journal ArticleDOI

No evidence for a placental microbiome in human pregnancies at term

TL;DR: No evidence to support the existence of a placental microbiome is found in a cross-sectional study comparing samples from two groups of full-term births using PCR amplification and sequencing techniques and bacterial culture experiments.
Journal ArticleDOI

Evidence of altered mucosa-associated and fecal microbiota composition in patients with Irritable Bowel Syndrome

TL;DR: It is demonstrated that alterations in the bacterial composition of the sigmoid colon of IBS patients were linked to symptoms and immune activation, and breath tests reflected the mucosa-associated bacterial composition, while there was no evidence for high prevalence of SIBO or small intestinal bacterial alterations in IBS.
Journal ArticleDOI

Caenorhabditis elegans as a Model To Determine Fitness of Antibiotic-Resistant Salmonella enterica Serovar Typhimurium

TL;DR: The fitness costs determined in the nematode were similar to those measured in mice, validating its use as a simple host model to evaluate bacterial fitness.
