Microbial communities in nature are dynamically evolving as member species change their interactions subject to environmental variations. Accounting for such context-dependent dynamic variations in interspecies interactions is critical for predictive ecological modeling. In the absence of generalizable theoretical foundations, we lack a fundamental understanding of how microbial interactions are driven by environmental factors, significantly limiting our capability to predict and engineer community dynamics and function.

Article Synopsis
  • Soil microorganisms play a crucial role in ecological functions, often relying on interactions between different populations in the soil microbiome.
  • A study was conducted using chitin, a key carbon and nitrogen source, to measure how a developed soil consortium (MSC-2) with eight diverse microbial species interacts during its decomposition, revealing distinct roles within the community.
  • The research showed that the most successful species were not necessarily the ones that degrade chitin but those that utilized byproducts of chitin decomposition, highlighting the importance of interspecies interactions and community dynamics over individual metabolic capabilities in nutrient cycling.

Background: Dogs have a species-specific susceptibility for developing mast cell tumours (MCTs). Mutations in the KIT proto-oncogene (KIT) are known to contribute to the neoplastic biology of mast cells. In dogs, the most common KIT mutation is an internal tandem duplication (ITD) in exon 11 which has been considered a useful prognostic supplement to traditional histopathological tumour grading.

: To assess the use of potassium bromide (KBr) as a therapeutic intervention for perennial ryegrass toxicosis (PRGT) in lambs fed ryegrass seed containing lolitrem B. : Male lambs aged 10-12 months (n = 43) were assigned to receive ryegrass seed containing lolitrem B, at a dose of 0.16 mg/kg/day (Groups 2, 3 and 4), or lucerne chaff and molasses (Groups 1 and 5).

This study was a retrospective chart review from January 1, 2015 through June 30, 2017, comparing the incidence of Clostridium difficile-associated diarrhea (CDAD) in patients taking select broad spectrum antibiotics with probiotics versus without probiotics. The purpose was to determine if probiotic use was associated with a reduction in the incidence of CDAD. A total of 5,574 hospital encounters were reviewed, showing a 0.
