AI Article Synopsis
- * Over a 12-year study, researchers found 64 cases of T. verrucosum infection among thousands of samples, with more cases observed in children (tinea capitis) versus adults (skin infections), and the infections were related to different exposure types.
- * The study noted a significant rise in infections over the last four years, which correlated with increased rainfall, suggesting that wetter conditions may enhance the spread of the fungus from cattle to humans, raising questions about the impact of climate change on these trends.
Article Abstract
Trichophyton verrucosum is a zoophilic dermatophyte, known as a causative agent of inflammatory mycoses of the skin and the scalp in humans. In this study, we reviewed all cases of T. verrucosum infection diagnosed in our laboratory over a 12-year period, to determine epidemiological and clinical characteristics. Among 18,340 samples analyzed, 5,186 cultured positive with dermatophytes (2674 patients), of which 64 samples (41 patients) were positive for T. verrucosum. Our data show that there was a strong influence of age on the type of lesion, with children and adults presenting more frequently with tinea capitis and skin infections, respectively (P < .0001). Infection of children and adults resulted more frequently from indirect and direct exposure to cattle, respectively (P < .01). We observed a marked increase of cases over the last 4 years, with a correlation of the number of cases and the mean annual rainfall (P < .05), suggesting that increasing humidity favors cattle infection, and thereby, human infection. Whether this increase is the consequence of climate changes remains to be determined but should be considered.
