ABSTRACT
BACKGROUND AND PURPOSE: Near-peer teaching is an innovative approach to teaching the skills of supervising and precepting while benefiting students with different levels of experience and academic training. This study describes near-peer activities in skills-based laboratory courses that provided opportunities for one-on-one teaching to benefit learners in the introductory lab courses while simultaneously training more advanced students for future supervisory and precepting roles. EDUCATIONAL ACTIVITY & SETTING: Three community pharmacy near-peer teaching simulations were designed and implemented: 1) Patient Counseling and Medication Adherence, 2) Dispensing and Patient Counseling, and 3) Drug Utilization Review and Prescriber Calls. These activities took place over two semesters of a pharmacy skills lab with all first- and third-year Doctor of Pharmacy students. FINDINGS: In Autumn 2019, 80% (111/139) of P1s and 67% (80/119) of P3s responded to the course evaluation survey. In Spring 2020, 73% (100/137) of P1s and 68% (80/118) of P3s responded to the course evaluation survey. The P3s reported increased confidence in their ability to provide meaningful feedback, while P1s reported increased confidence in communicating with patients and healthcare providers. Performance data revealed that most P1s and P3s completed dispensing and communication activities accurately using a near-peer approach. Overall, the P1s and P3s felt the activities were valuable learning experiences. SUMMARY: The near-peer activities described in this study fill a gap in the training of pharmacy graduates for future precepting and supervisory roles. Evaluation of these near-peer activities suggest that both junior and senior learners benefit from simulated preceptor-intern interactions, supporting this innovative approach to address supervisory and precepting responsibilities.

Aquaculture is an important tool for solving the growing worldwide food demand, but infectious diseases of farmed animals represent a serious roadblock to continued industry growth. Therefore, it is essential to understand the microbial communities that reside within the built environments of aquaculture facilities to identify reservoirs of bacterial pathogens and potential correlations between commensal species and specific disease agents. Here, we present the results from 3 years of sampling a commercial rainbow trout aquaculture facility. We observed that the microbial communities residing on the abiotic surfaces within the hatchery were distinct from those residing on the surfaces at the facility's water source as well as the production raceways, despite similar communities in the water column at each location. Also, a subset of the water community seeds the biofilm communities. Lastly, we detected a common fish pathogen, Flavobacterium columnare, within the hatchery, including at the source water inlet. Importantly, the relative abundance of this pathogen was correlated with clinical disease. Our results characterized the microbial communities in an aquaculture facility, established that the hatchery environment contains a unique community composition and demonstrated that a specific fish pathogen resides within abiotic surface biofilms and is seeded from the natural water source.

In November 2018, Vagococcus salmoninarum was identified as the causative agent of a chronic coldwater streptococcosis epizootic in broodstock brook trout (Salvelinus fontinalis) at the Iron River National Fish Hatchery in Wisconsin, USA. By February 2019, the epizootic spread to adjacent raceways containing broodstock lake trout (Salvelinus namaycush), whereby fish were found to be coinfected with Carnobacterium maltaromaticum and V. salmoninarum. To differentiate these two pathogens and determine the primary cause of the lake trout morbidity, a quantitative real-time PCR (qPCR) was developed targeting the C. maltaromaticum phenylalanyl-tRNA synthase alpha subunit (pheS) gene. The qPCR was combined with a V. salmoninarum qPCR, creating a duplex qPCR assay that simultaneously quantitates C. maltaromaticum and V. salmoninarum concentrations in individual lake trout tissues, and screens presumptive isolates from hatchery inspections and wild fish from national fish hatchery source waters throughout the Great Lakes basin. Vagococcus salmoninarum and C. maltaromaticum were co-detected in broodstock brook trout from two tribal hatcheries and C. maltaromaticum was present in wild fish in source waters of several national fish hatcheries. This study provides a powerful new tool to differentiate and diagnose two emerging Gram-positive bacterial pathogens.

Diseases caused by the fish pathogens Flavobacterium columnare and Flavobacterium psychrophilum are major contributors of preventable losses in the aquaculture industry. The persistent and difficult-to-control infections caused by these bacteria make timely intervention and prophylactic elimination of pathogen reservoirs important measures to combat these disease-causing agents. In this study, we present two independent assays for detecting these pathogens in a range of environmental samples. Natural water samples were inoculated with F. columnare and F. psychrophilum over 5 orders of magnitude, and pathogen levels were detected using Illumina MiSeq sequencing and droplet digital PCR. Both detection methods accurately identified pathogen-positive samples and showed good agreement in quantifying each pathogen. Additionally, the real-world application of these approaches was demonstrated using environmental samples collected at a rainbow trout (Oncorhynchus mykiss) aquaculture facility. These results show that both methods can serve as useful tools for surveillance efforts in aquaculture facilities, where the early detection of these flavobacterial pathogens may direct preventative measures to reduce disease occurrence. IMPORTANCE Early detection of a deadly disease outbreak in a population can be the difference between mass mortality or mitigated effects. In the present study, we evaluated and compared two molecular techniques for detecting economically impactful aquaculture pathogens. We demonstrate that one of these techniques, 16S rRNA gene sequencing using Illumina MiSeq technology, provides the ability to accurately detect two freshwater fish pathogens, F. columnare and F. psychrophilum, while simultaneously profiling the native microbial community. The second technique, droplet digital PCR, is commonly used for pathogen detection, and the results obtained using the assays we designed with this method served to validate those obtained using the MiSeq method. These two methods offer distinct advantages. The MiSeq method pairs pathogen detection and microbial community profiling to answer immediate and long-term fish health concerns, while the droplet digital PCR method provides fast and highly sensitive detection that is useful for surveillance and rapid clinical responses.

A draft genome sequence of Aeromonas popoffii ID682, isolated from a natural water source in Idaho, is presented here. A. popoffii is a relatively understudied species within a diverse, expanding freshwater genus of bacteria. Here, we describe only the second genome published for this species to date.
ABSTRACT
We present a draft genome sequence of Janthinobacterium lividum strain ID1246, isolated from within a rainbow trout hatchery raceway. Janthinobacterium spp. are well-known producers of antimicrobial compounds. Due to the unique isolation source, this genome may yield novel biosynthetic gene clusters.
ABSTRACT
Objective. To assess the impact of the Patient Voices series on Doctor of Pharmacy (PharmD) students.Methods. A series of patient speakers and integrated simulation activities focused on underserved populations, otherwise known as the Patient Voices series, was embedded into a pharmacy skills laboratory curriculum. First-year PharmD students' self-ratings of confidence were compared on pre- and post-course surveys. Using evaluations from first-year introductory pharmacy practice experiences (IPPEs), student self-evaluation data were compared to preceptor evaluations of student performance. Open-ended responses to course evaluations from first- and second-year PharmD students and student reflections from third-year PharmD students were assessed using conventional content analysis to identify and characterize student perceptions.Results. Significant increases were observed in first-year students' confidence to show empathy (mean, 4.2 to 4.7) and to interact with patients from underserved communities (mean, 2.2 to 4.2). Preceptor ratings of students' empathy were consistent with the students' self-rated abilities, while students' self-ratings on cultural sensitivity were higher than the preceptors' ratings. Qualitative analysis of course evaluation surveys and reflections revealed common themes identified by students, such as understanding different perspectives, increased empathy for patients, and the value of including this content in the curriculum.Conclusion. Student confidence to interact with patients from a variety of underserved populations increased following introduction of the Patient Voices series into the PharmD curriculum. Students perceived the series to be a valuable learning experience.
