Article

Background RT-PCR has become the primary method to diagnose viral diseases, including SARS-CoV-2. RT-PCR detects RNA, not infectious virus, thus its ability to determine duration of infectivity of patients is limited. Infectivity is a critical determinant in informing public health guidelines/interventions. Our goal was to determine the relationshi...

KEY POINTS Bartonella quintana, the causal agent of trench fever, is transmitted by body lice (Pediculus humanus var. corporis). Although B. quintana is notorious for causing disease in the First World War, outbreaks of trench fever have recently occurred in urban populations experiencing homelessness. B. quintana causes culture-negative endocard...

We describe a case of Bartonella quintana endocarditis in an 11-year-old child from Northern Manitoba, Canada. This case demonstrates the neglected endemicity of B. quintana in Northern Canada and highlights the need for improved case finding and elucidation of specific risk factors for B. quintana infection in the Canadian North. Considering B. qu...

Background: Bartonella are gram-negative bacilli not identified by routine bacterial culture. The objectives of this study were to review the results of all serologic testing for Bartonella ordered in Manitoba, Canada, and to review cases with positive test results among adults to assess species identification, risk factors, clinical manifestation...
Article
Full-text available
Diagnostic capacity is a key part of public and global health preparedness for newly emerging or spreading infections and the recent global spread of monkeypox illustrates the consequences of inadequate diagnostic capacity. Monkeypox has a syndromic diversity, from asymptomatic infection to isolated skin lesions, to fever and disseminated rash.1,2...

Rationale: Lyme disease is a tick-borne disease caused by the spirochete B. burgdorferi, and patients often present with symptoms comparable to a viral-like illness. The diagnosis can be challenging given its wide range of manifestations and diagnostic testing can take days or longer. Here, we present a case of Lyme disease presenting as brachial...

A 41-year-old female presented to a walk-in clinic 1 day after an acute onset of nausea and severe sharp epigastric pain. The patient’s medical history was notable for Helicobacter pylori infection treated 1 year earlier. Her past surgical history included a remote appendectomy and carpel tunnel release. The patient did not take medications regular...
Article

A 63-year-old male with mechanical aortic valve replacement presents with Trichosporon mucoides endocarditis. Eosinophilia was noted, which has recently been described in invasive trichosporonosis. He was treated successfully with combination voriconazole and terbinafine therapy. He was deemed not to be a cardiac surgery candidate, due to excessive...
Article

Introduction In India, the HIV epidemic is concentrated among Key Populations (KPs), such as men who have sex with men (MSM), who bear a disproportionate burden of HIV disease. Conventional targeted interventions (TI) mitigate HIV transmission among MSM by focusing on physical hotspots. As increasingly, there is a shift within India’s MSM community...
Article
Full-text available
Although uncommon, gonococcal endocarditis often causes extensive cardiac destruction and may be fatal without prompt antimicrobial therapy and cardiovascular surgery. Cases of gonococcal endocarditis highlight an abrupt re-emergence of widespread gonococcal disease. As N. gonorrhoeae remains one of the most common causes of arthritis and arthralgi...
Article

Background: Leprosy is uncommon in Canada. However, immigration from leprosy-endemic areas has introduced the infection to a Canadian context, in which most doctors have little knowledge of the disease. Although post-exposure chemoprophylaxis (PEP) is reported to decrease leprosy transmission, no Canadian guidelines advise clinical decision making...
Poster

Trichosporon species are urease-positive, non-encapsulated yeasts commonly associated with benign hair and nail infections. Trichosporon species rarely cause endocarditis among both immunocompetent and immunocompromised hosts. To our knowledge, there is only one other published case of prosthetic valve endocarditis due to Trichosporon mucoides....

Here, we describe a case of nosocomial mucormycosis of the thigh in an immunocompromised patient admitted with COVID-19 acute respiratory distress syndrome.
Article
Full-text available
Infection prevention and control measures are used to contain outbreaks of carbapenemase-producing Enterobacteriaceae. We report the absence of transmission of Klebsiella pneumoniae carrying New Delhi metallo-β-lactamase and oxacillinase-48 genes among 19 screened contacts of an index case after 14 months of routine practices in a long-term care fa...

Tularemia is a zoonotic disease caused by the gram negative coccobacillus Francisella tularensis, a Biosafety Level 3 pathogen and potential agent of bioterrorism. We describe 2 cases of perigenital ulcer disease caused by Francisella tularensis subspecies holarctica in Manitoba, Canada. These cases caused inadvertent exposure among laboratory pers...

Appendix 1 (as submitted by authors): Supplementary information Description of three additional patients diagnosed with Bartonella quintana infection in Winnipeg. 3 of the 4 patients presented here are Indigenous. The authors do not intend, even inadvertently, to perpetuate harmful stereotypes of Indigeneity. Instead, we hope these cases remind re...

The coronavirus disease (COVID-19) pandemic is causing wide-spread interruptions in medical education. With little warning, clinical rotations were cancelled and medical students were sent home. While pre-clinical students transitioned to online curricula, clinical students were left without discreet educational goals. Simultaneously, medical docto...

The ongoing North American epidemic of intravenous opioid and methamphetamine use increases the occurrence of bacteremia from environmental organisms. Here, we report a case of Mycobacterium mucogenicum bacteremia and associated nodular soft tissue infection in a person who uses tap water to inject drugs.

1 La sensibilité d’un test dépend du moment du prélèvement de l’échantillon. Le dépistage du coronavirus du syndrome respiratoire aigu sévère 2 (SRAS-CoV-2) repose sur la RT-PCR, soit l’amplification en chaîne par polymérase couplée à une transcription inverse du matériel génétique du SRAS-CoV-21 . La sensibilité de ce type de tests est optimale lo...

Loiasis is a filarial disease endemic to areas of Central and West Africa. We present a case of Loa loa microfilaremia in a patient with HTLV-1-related adult T-cell lymphoma. This case may suggest the possible role of cellular immunity in controlling microfilaria burden.

Background: TB is the leading cause of death among patients with HIV worldwide. In Northern Uganda, the rates of TB and HIV are high due to recent conflict and resource limitations. A challenge in the management of TB-HIV co-infection involves rifampin’s induction of cytochrome 3A4 and the ensuing reduction of protease inhibitors (PI) to subtherape...

Impoverished communities often turn to illegal extraction of resources from protected areas to alleviate economic pressures or to make monetary gains. Such practices can cause ecological damage and threaten animal populations. These communities also often face a high disease burden and typically do not have access to affordable health care. Here we...

TB is the leading cause of death among patients with HIV worldwide. In Northern Uganda, the rates of TB and HIV are high due to recent conflict and resource limitations. A challenge in the management of TB-HIV co-infection involves rifampin’s induction of cytochrome 3A4 and the ensuing reduction of protease inhibitors (PI) to subtherapeutic concentrations. Our goal is to describe the cohort of TB-HIV co-infected patients on problematic combinations of rifampin and PIs at Gulu Regional Referral Hospital (GRRH).

With the advent of multidrug leprosy therapy in the 1980s, the global prevalence rate of leprosy fell from 5 million to just over 200 000 in 2014. Nevertheless, the incidence rate has remained globally stagnant at 200 000 reported annually, with India and Brazil continuing to demonstrate elevated case numbers despite therapeutic and public health advancement. There is significant controversy regarding the role of chemoprophylaxis of household contacts, a population that is most susceptible to leprosy transmission. Immigration from leprosy endemic areas, notably India, Vietnam and the Philippines, has introduced leprosy to a Canadian context where health care practitioners have little to no knowledge of the disease. Here, we evaluate the practice patterns of Canadian infectious disease and tropical medicine specialists regarding chemoprophylaxis of household contacts of patients with leprosy.
