Exploring Fungal Invaders in the Urinary Tracts of Cats and Dogs

Abstract

Lower urinary tract infections (UTIs) are common in cats and dogs, often caused by various infectious agents, including fungi. Candida albicans is the most frequently isolated fungal species in the urine of these animals, while other fungi like Torulopsis spp. and Cryptococcus spp. have also been identified. Fungal UTIs are rare, accounting for less than 1% of cases, partly due to insufficient fungal culture testing following bacterial infections. Factors such as antibiotic use, compromised immune systems, and underlying conditions like diabetes predispose animals to these infections. Diagnosis relies on clinical symptoms, laboratory tests, and culture of pathogens, while treatment typically involves addressing predisposing factors and using antifungal medications like fluconazole, which is effective and safely excreted in urine.
