Communicable E34: WHO's Fungal Priority Pathogens List
Fungal infections and disease have long been overlooked in terms of healthcare burden, with poor diagnostics and limited options for treatment and management. In 2022, the WHO published its first Fungal Priority Pathogens List as an effort to establish a global prioritised framework that addresses unmet research and development needs in fungal disease and antifungal resistance, as well as
Communicable E33: Ethics in infectious diseases
Ethics in the field of infectious disease can be a delicate interplay between treating the individual patient and protecting the collective health of a society. Sometimes these two mandates go hand in hand; at other times they can appear to be in conflict. In this episode of Communicable, Dr. Angela Huttner invites Drs. Zeb Jamrozik (Melbourne, Australia) and Beenish Syed (Karachi, Pakist
Communicable E32: Fluoroquinolones - to heal or harm?
Fluoroquinolones (FQs) are valuable given their broad-spectrum activity against Gram-positive and Gram-negative bacteria and their high penetration into various tissues. Yet FQs have also caused concern, with some market withdrawals, important and sometimes long-lasting adverse drug events, and substantial collateral effects on the microbiota. In this episode of Communicable, hosts Emily
Communicable E31: Climate change and fungal spread
The adaptability of fungi to warmer temperatures is an obvious consequence of climate change. Perhaps less obvious is the role climate change has played on fungal pathogens emerging as a global health concern. While humans are mostly protected from fungal infections by our immune system and body temperature, a warming global climate could subvert the status quo. Some fungi are already ada
Communicable E30: WHO's first-ever guideline on meningitis
Meningitis remains a major global health threat, with an estimated 2.5 million cases each year; of these, one in six results in death and one in five in long-term disabilities. Although meningitis “can strike anyone, anywhere in the world,” outbreaks disproportionately impact low- and middle-income countries, where diagnostic and treatment resources are limited. In efforts to address this
Communicable E29: Bacterial vaginosis & male partners
Bacterial vaginosis (BV) was long considered not to be a sexually transmitted infection (STI), and treatment was only for women to bear. That was the convention at least until Catriona Bradshaw and her team at the Melbourne Sexual Health Centre published their groundbreaking clinical trial results earlier this year, demonstrating that treating male partners of women with BV prevented recu

Communicable E13 - The Wild West of publishing today: predatory journals and how to deal with them
The market of predatory publishing is as lucrative as it is unethical. Predatory journals are disguised as legitimate entities, and prey on both early-career academics and the naïve. In this episode of Communicable, hosts Angela Huttner and Marc Bonten are joined by Editors-in-chief Ursula Hofer (Lancet Infect Dis) and Leonard Leibovici (CMI) to discuss the various schemes of the ‘Wild We
Communicable E12 - The Nightmare Series, part 3: How to deal with vancomycin-resistant enterococci
Enterococci are commensal microbes, part of the healthy microflora populating the human gut. But they are also opportunistic pathogens and notorious nosocomial agents with intrinsic traits that promote their pathogenesis and make them difficult to kill. In the third instalment of the Nightmare Series, hosts Angela Huttner and Thomas Tängdén are joined by enterococcal experts Kimberly Klin
Communicable E11 - Nightmare series, part 2: How to deal with carbapenemase producers
Carbapenemase producers are a nightmare for clinicians.

Communicable E5 - Beauty is in the 'I' of the beholder: EUCAST updates
The ‘I’ (intermediate susceptibility) in a EUCAST-guided antibiogram never meant impending resistance to your antibiotic. It was never meant to make you find the one ‘S’ (invariably a carbapenem) and use it instead—even if many clinicians did. In this episode of Communicable, hosts Marc Bonten and Angela Huttner welcome Profs. Christian Giske (outgoing chair) and Sören Gatermann (newly el
