Article Synopsis
  • Piscirickettsiosis, caused by the pathogen P. salmonis, significantly impacts the Chilean aquaculture industry, leading to major economic losses, and traditional genotyping methods are limited in cost and expertise requirements.
  • This study introduces Loop-mediated Isothermal Amplification (LAMP) as a faster, cheaper, and simpler alternative for diagnosing P. salmonis, developing specific assays for both species identification and differentiation between its genogroups LF-89 and EM-90.
  • LAMP assays showed sensitivity and specificity on par with traditional methods while being more suitable for field use, indicating potential for improved disease management and surveillance in salmonid aquaculture.

The innate immune response in , mediated by pattern recognition receptors (PRRs), is crucial for defending against pathogens. This study examined DDX41 protein functions as a cytosolic/nuclear sensor for cyclic dinucleotides, RNA, and DNA from invasive intracellular bacteria. The investigation determined the existence, conservation, and functional expression of the gene in .

Renibacterium salmoninarum is one of the oldest known fish bacterial pathogens. This Gram-positive bacterium is the causative agent of Bacterial Kidney Disease (BKD), a chronic infection that primarily infects salmonids at low temperatures. Externally, infected fish may show exophthalmos, skin blisters, ulcerations, and hemorrhages at the base of the fins and along the lateral line.

The aim of the present study was to compare the frequency of consumption, access to purchase, and type of preparations with pulses among people who eat a vegetarian/vegan or non-vegetarian diet during the COVID-19 pandemic. Cross-sectional surveys were distributed using different digital platforms and social networks. We investigated the frequency of consumption, access to purchase any type of preparations.

Given the psychological and financial costs involved with failing a clinical course, especially in developing countries, an alternative educational method was tested with students who had to repeat the year-long endodontic course at the University of Chile Faculty of Dentistry. The objectives of the intervention were to deepen theoretical knowledge and practical experiences, as well as to reinforce personal confidence in an endodontic clinical setting for students who failed the regular endodontic course. The aim of this study was to evaluate the success of this new model of educational intervention.

The aim of this double-blind randomized controlled clinical trial was to evaluate the reduction of dentin sensitivity using an oxalate-based compound, placed under adhesive restorations, during a four-month period. One hundred three preoperatively sensitive teeth, on 36 patients aged 25-66 years (mean, 40.3±7), were included in the study.
