Characterization of extended-spectrum beta-lactamase-producing from recreational water in Athens, GA, using an undergraduate laboratory module.

We present a laboratory module that uses isolation of antibiotic-resistant bacteria from locally collected stream water samples to introduce undergraduate students to basic microbiological culture-based and molecular techniques. This module also educates them on the global public health threat of antibiotic-resistant organisms. Through eight laboratory sessions, students are involved in quality testing of water sources from their neighborhoods, followed by isolation of extended-spectrum beta-lactamase-producing .

Striving Towards National Lower-Risk Gambling Guidelines: An Empirical Investigation Among a Sample of Swedish Gamblers.

Several countries, including Canada and Australia, have developed public health-based lower-risk gambling limits to differentiate lower-risk from higher-risk gambling. This study aimed to identify a preliminary set of lower-risk gambling limits (gambling frequency, duration, expenditure, expenditure as a proportion of personal net income, and diversity), and investigate if gambling types are linked to additional harms, in a Swedish context. The study involved secondary analyses of two online survey studies using the Gambling Disorder Identification Test (GDIT).

Hospital-level variation in cardiac rehabilitation metrics.

Background: To inform the delivery of cardiac rehabilitation (CR) care nationwide at the hospital level, we described hospital-level variation in CR metrics, overall and stratified by the hospital's tier of cardiac care provided.

Methods: This retrospective cohort analysis used Medicare fee-for-service (FFS) data (2018-2020), Parts A and B, and American Hospital Association (AHA) data (2018). We included beneficiaries with an acute myocardial infarction (AMI), percutaneous coronary intervention (PCI), or coronary artery bypass graft (CABG) in 2018, aged ≥65 years, and continuously enrolled in a FFS plan.

Subcutaneous inoculation of Escherichia coli in broiler chickens causes cellulitis and elicits innate and specific immune responses.

Background: Cellulitis caused by Escherichia coli is a common cause of condemnation of broiler chickens at slaughter worldwide and is associated with economic losses and a possible negative impact on animal welfare. The study objective was to monitor clinical signs and immune responses after subcutaneous E. coli inoculation (1.

Microbial transcriptional responses to host diet maintain gut microbiome homeostasis in the American cockroach.

Diet is considered a key determinant of gut microbiome composition and function. However, studies in the American cockroach have revealed surprising stability in hindgut microbiome taxonomic composition following shifts in host diet. To discover microbial activities underlying this stability, we analyzed microbial community transcriptomes from hindguts of cockroaches fed diverse diets.
