Although rare in North America, it can present significant diagnostic and therapeutic challenges. Case Presentation: We report a 36-year-old male from Quebec, Canada, with locally acquired primary pulmonary CE who presented to the emergency department with a two-month history of shortness of breath, cough, and hemoptysis. Laboratory investigations showed mild...

We conducted an integrated analysis that combines electrophysiological and transcriptomic profiling, along with machine learning, of islet cells from T1D donors. The few surviving β-cells exhibit altered electrophysiological properties and transcriptomic signatures indicative of increased antigen presentation, metabolic...

Despite an existing biological rationale for the combination of cefazolin and linezolid for methicillin-susceptible S. aureus (MSSA), this combination has yet to be evaluated for in vitro synergy. We employed the checkerboard and E-test methods of synergy assessment to evaluate cefazolin in combination with...

This study investigated whether seropositivity to C. burnetii or Bartonella could be detected among patients with persistent fever for which an infectious or inflammatory etiological diagnosis had been previously established in three LMICs. Our study tested sera from Cambodian, Nepalese, and Sudanese participants using indirect immunofluorescent antibody assays...

Reports of loss of efficacy (LOE) of the MLs in the early 2000s led to in-depth research which identified the presence of resistant strains of D. immitis in the Southeast United States. Detailed genetic analysis of such parasites identified genetic markers for resistance. In order to evaluate the prevalence of these markers in Ontario...

Resistance to antiparasitic drugs is affecting control of many pathogens in human and veterinary medicine. In veterinary medicine, particular attention has been focused on resistance to parasites of livestock, including helminths, ectoparasites and protozoa, as an effect of intensive treatment regimens that promote economic sustainability of production systems. Less attention has been given to drug...

The results show that the prevalence of viral hepatitis among immigrants is higher than the general Canadian population. However, grouping all immigrants into one category masks important variation, and potentially over-estimates the burden of HBV and HCV among immigrants. Strengthening our understanding of hepatitis prevalence among immigrants can improve our ability to...

Improved awareness of this common dermatosis among physicians and travellers, as well as improved access to effective therapies, will reduce associated morbidity. Wed, 20 Aug 2025 06:00:00 -0400
