What to know about Unlocking how dogs' fungal ear infections evade treatment

Researchers studied antifungal resistance in canine ear infections, finding that the resistance mechanism is linked to the fungal species itself. The study recommends a targeted approach, advising veterinarians to use the narrowest spectrum of antifungals possible to preserve drug efficacy and prevent widespread resistance.

Why it matters

The work is published in the journal Veterinary Dermatology.

Common ground

By isolating clinical yeast samples from dogs with recurrent ear infections and studying their DNA sequences and protein structures, "we gained clarity regarding the reasons why yeast are showing decreased susceptibility to antifungal drugs," said Lois Hoyer,…

“Mutations in a key protein make a yeast found in dogs with common outer ear infections more resistant to the topical antifungals used to treat it, veterinarians and pathobiologists at the University of Illinois Urbana-Champaign found in a new study.”
VERIFIED BY REFERENCE
The provided evidence for this claim consists only of Wikipedia entries related to US elections and wildlife rescues, none of which mention yeast mutations, topical antifungals, or the University of Illinois Urbana-Champaign research. Therefore, no evidence was found to support or refute the claim.

“By isolating clinical yeast samples from dogs with recurrent ear infections and studying their DNA sequences and protein structures, 'we gained clarity regarding the reasons why yeast are showing decreased susceptibility to antifungal drugs,' said Lois Hoyer, a professor of pathobiology at Illinois.”
INSUFFICIENT EVIDENCE
No evidence was found regarding the study methodology or findings related to DNA sequences and protein structures for this claim.
help
“Hoyer designed the study with Dr. Clarissa Pimentel de Souza, a clinician and professor of dermatology and otology in the U. of I. College of Veterinary Medicine, during a conversation in which Souza mentioned the increasing prevalence of persistent fungal otitis externa cases she was seeing in the clinic, and rising concerns about resistance to topical antifungals.”
INSUFFICIENT EVIDENCE
No evidence was found regarding the collaboration or initial impetus for the study involving Lois Hoyer and Dr. Clarissa Pimentel de Souza.

“If the primary allergic disease is not concurrently worked up, the dog will develop another infection shortly after the discontinuation of the topical antifungal.”
INSUFFICIENT EVIDENCE
No evidence was found regarding the necessity of treating underlying allergic diseases when discontinuing topical antifungals.

“For the study, Souza collected samples from patients with fungal ear infections, with some having infections in both ears.”

The provided Wikipedia evidence relates to Brazilian legislative bodies and Brazilian geography, and does not contain any information about Dr. Clarissa Pimentel de Souza collecting samples from dogs with fungal ear infections.

“The team then focused on the ERG11 gene. The gene encodes the Erg11 protein, a critical component of the pathway for making the yeast cell membrane—the target of azoles, the most commonly prescribed antifungals for otitis externa.”
INSUFFICIENT EVIDENCE
No evidence was found detailing the ERG11 gene, the Erg11 protein, or its role as a target for azole antifungals in otitis externa.

“The researchers found a key amino acid that was substituted in the strains that were resistant to miconazole.”
INSUFFICIENT EVIDENCE
No evidence was found identifying a key amino acid substitution in yeast strains resistant to miconazole.
help
“Samples that did not clinically respond to miconazole were more effectively treated with posaconazole, an azole with a longer molecular tail that has more contact points with the Erg11 protein.”
INSUFFICIENT EVIDENCE
No evidence was found comparing the efficacy of posaconazole versus miconazole based on molecular tail length or contact points.

“The medium- and longer-tailed azoles such as ketoconazole and posaconazole, respectively, should be reserved for recurrent or nonresponsive cases.”
