Abstract

<abstract abstract-type="main" id="jde12575-abs-0001"> <title>Abstract</title> <p> <italic>Trichophyton mentagrophytes</italic> were isolated from 19 of 20 guinea pigs in a children's corner of a zoo. The nucleotide sequence identity of the internal transcribed spacer region among 19 guinea pig isolates was 99%, including the reference strain of animal type 3 of <italic>T. mentagrophytes</italic>. The genomic DNA of all isolates were investigated for the mating (MAT) gene by specific polymerase chain reaction. The alpha‐box gene was detected in all 19 isolates, while the high‐mobility‐group (<italic>HMG</italic>) gene was detected in only one of 19 isolates. Therefore, the guinea pig population harbored at least 2 MAT types of <italic>Arthroderma vanbreuseghemii</italic>. The <italic>T. mentagrophytes</italic> that was prevalent in this population may constitute a constant source of infection for persons coming into contact with guinea pigs.</p> </abstract>
