Some sulfate-reducing bacteria (SRB), mainly belonging to the family, have evolved the capability to conserve energy through microbial extracellular electron transfer (EET), suggesting that this process may be more widespread than previously believed. While previous evidence has shown that mobile genetic elements drive the plasticity and evolution of SRB and iron-reducing bacteria (FeRB), few have investigated the shared molecular mechanisms related to EET. To address this, we analyzed the prevalence and abundance of EET elements and how they contributed to their differentiation among 42 members of the family and 23 and 59 members of and , respectively.

Objective: To determine the psychometric properties of the Spanish version of the Jeffries questionnaire to assess perception, satisfaction and learning results in Clinical Simulation (QJSC) for students of Health Science degrees.

Method: For the transcultural adaptation to the Spanish language of the QJSC questionnaire, the inverse method was applied with a back translation. Internal consistency analysis was performed to assess reliability, analysed with Cronbach's alpha, a value between 0.

Sulfate reducing prokaryotes (SRP) are a phylogenetically and physiologically diverse group of microorganisms that use sulfate as an electron acceptor. SRP have long been recognized as key players of the carbon and sulfur cycles, and more recently, they have been identified to play a relevant role as part of syntrophic and symbiotic relations and the human microbiome. Despite their environmental relevance, there is a poor understanding about the prevalence of prophages and CRISPR arrays and how their distribution and dynamic affect the ecological role of SRP.
