Outbreak investigations of and frozen raw breaded chicken: the mitigation of a significant public health issue in Canada.

In May 2017, whole-genome sequencing (WGS) became the primary subtyping method for in Canada. As a result of the increased discriminatory power provided by WGS, 16 multi-jurisdictional outbreaks of associated with frozen raw breaded chicken products were identified between 2017 and 2019. The majority (15/16) were associated with , while the remaining outbreak was associated with Heidelberg.

Chemical Kinetics Investigations of Dibutyl Ether Isomers Oxidation in a Laminar Flow Reactor.

The combustion kinetics of three symmetric diesel-boiling-range ether isomers were investigated experimentally using a plug flow reactor. The isomers were di--butyl ether (DNBE), diisobutyl ether (DIBE), and di--butyl ether (DSBE). The flow reactor experiments employed oxygen as the oxidizer and helium as the diluent, with oxidation carried out at atmospheric and elevated pressure conditions and temperatures from 400 to 1000 at 20 K intervals.

Perceived Negative Menstrual Cycle Symptoms, but not Changes in Estrogen or Progesterone, are Associated with Impaired Cycling Race Performance.

Purpose: To examine the relationship between menstrual cycle (MC) phase-dependent fluctuations of estrogen and progesterone and virtual cycling race performance, with a secondary aim of correlating perceived MC-related symptoms with performance.Methods: In a novel observational study design, thirty-seven female cyclists/triathletes not using any hormonal contraception completed one virtual cycling race [19.5 km time trial (TT)] per week across a one-month period (totaling four races).

Epididymo-Orchitis Mimicking Malignancy Resulting From Intravesical Bacillus Calmette-Guerin Immunotherapy for Bladder Cancer: An Attempt to Understand Pathophysiology, Diagnostic Challenges, Patients' Implications and Future Directions.

This case report describes an 85-year-old patient who presented with painless, unilateral right testicular swelling of 2 months' duration. This raised the possibility of testicular cancer, especially given his recent treatment for bladder cancer, which included adjuvant intravesical bacillus Calmette-Guerin (BCG) therapy. This poses a diagnostic dilemma regarding tuberculosis (TB) of the testis, BCG complications or a true testicular malignancy.

Everything but the kitchen sink: The use of multiple hypothesis generation methods to investigate an outbreak of Enteritidis associated with frozen profiteroles and eclairs.

In December 2018, an outbreak of Enteritidis infections was identified in Canada by whole-genome sequencing (WGS). An investigation was initiated to identify the source of the illnesses, which proved challenging and complex. Microbiological hypothesis generation methods included comparisons of isolate sequence data to historical domestic outbreaks and international repositories.
