Abstract:
... Microbiome research attributes to whole microbiomes a causal role in the occurrence of different health outcomes. I argue, following some distinctions about causal relationships and explanations made within a philosophical account of causation, the “interventionist account,” that such claims need more scrutiny. ...

Abstract:
... Since its discovery, Helicobacter pylori has been identified as the causative agent of various gastric diseases. H. pylori produces myriads of disease-associated virulence factors. These bacterial determinants can be distinguished as cell-binding factors, immunoregulatory components, survival factors, toxins, and effector proteins. For most of these factors there is consensus about their classific ...

Abstract:
... Bacterial osteomyelitis in veterinary patients can be challenging to diagnose and treat, given limited therapeutic options and reported success rates. Osteomyelitis is frequently associated with surgical implant devices, including those required to optimise stability and healing of fractures. However, management of osteomyelitis sometimes necessitates the removal of these surgical implant devices ...
