Candida lusitaniae is a Candida yeast that can be detected in the gastrointestinal tract and on mucosal surfaces. It is usually not one of the Candida yeasts expected to dominate a dog’s gut profile. Higher levels may suggest that the gut environment has shifted in a way that allows a less typical Candida yeast to become more noticeable. This may happen when bacterial competition is reduced, after antibiotic use, during changes in immune resilience, or when the balance between bacteria and fungi is disrupted. Higher levels may be seen together with altered stool quality, gas, recurring digestive changes, or mild mucosal irritation. Candida lusitaniae levels can help show whether less typical Candida species are part of a broader fungal pattern.
