Plain-English summary
A young girl and her mother developed skin rashes after getting a domestic cat five months earlier. About three months after bringing the cat home, both the girl and her mother noticed these skin eruptions. Tests showed that both of them had a fungal infection caused by a type of fungus called Microsporum canis, which they likely caught from their cat. The cat also tested positive for this fungus, and while some tests showed that the fungus was somewhat resistant to certain medications, it was still the same strain as the one affecting the mother and daughter. The findings suggest that testing for how well treatments work is important, especially since there are concerns about drug-resistant infections.
Abstract
The patient was a girl (case 1) and her mother (case 2). The family had purchased a domestic cat five months previously. Three months later, both patients developed eruptions. Mycological examinations were positive in both cases, and the cat tested positive on the hairbrush test. The macroconidia were thick only in the cat strain, and drug susceptibility testing showed mildly low levels of terbinafine and itraconazole. However, a molecular biological analysis of these three strains showed 100% identity with reference strains of Microsporum canis. Since there have been recent reports of drug-resistant dermatophytosis, drug-susceptibility testing is considered necessary.
