Deadly fungus in dogs’ ears could infect humans: ‘We need to be vigilant’

Beneath the innocent facade of your beloved canine companion lies a potential threat that could be deadly. Scientists have made a chilling discovery: a drug-resistant fungus called Candida auris, originating from the ear canals of dogs. This fungus is particularly alarming because certain strains are unaffected by common anti-fungal treatments used for other Candida infections. ( The Centers for Disease Control and Prevention warns that C. auris poses a serious health risk, and recent findings in stray dogs from India suggest that dogs could transmit the fungus to humans. Medical experts estimate that over one-third of patients with serious C. auris infections may not survive. ( The World Health Organization has classified C. auris as a “critical priority” fungal disease, further emphasizing the urgency of the situation.

The revelation of C. auris in the ears of four stray dogs is a cause for concern, as it suggests that these animals could serve as carriers, spreading the fungus to other animals and humans. Jianping Xu, a professor at McMaster University in Canada and co-author of the study, stresses the significance of this discovery, given the presence of stray dogs in many parts of the world. The potential for transmission raises alarm bells, demanding enhanced surveillance of dogs, domesticated pets, and wild animals in regions where C. auris is prevalent. ( While the transmission of C. auris from human to human is well-documented, the mode of transmission among animals or from animals to humans remains less clear, requiring further investigation.

This marks the first time C. auris has been isolated from any animal. DNA analysis of the fungus found in the four dogs indicates genetic similarities to strains found in humans, heightening the risk of cross-species transmission. ( The study’s publication in the Journal of Fungi underlines the significance of these findings. The need for vigilance in monitoring animals, including dogs and other pets, is emphasized by Xu, recognizing that regions where C. auris is endemic necessitate particular attention.

The threat posed by C. auris is especially critical in hospital settings, where severe outbreaks can occur. New York State has witnessed a significant number of C. auris cases, with 379 confirmed infections of this dangerous, drug-resistant fungus in 2022. The state joins the ranks of Nevada, California, and Florida as the regions with the highest incidence of C. auris infections. The escalating numbers from the past year indicate the pressing need for proactive measures to combat this resilient and potentially fatal fungal disease.

The emergence of C. auris in dogs raises urgent concerns about the health risks posed to humans. The interplay between animals and humans in the transmission of this drug-resistant fungus demands careful monitoring and further investigation. ( As the World Health Organization designates C. auris a “critical priority” fungal disease, the global community must work together to mitigate its spread and protect public health.
