It has been recently shown that, during the
adhesion of T. mentagrophytes arthroconidia to the
stratum corneum surface, the formation of elongated
fibrillary structures that appear to anchor and connect
the arthroconidium to the tissue surface occurs. This
may also prevent its removal from the host tissue.
However, during the infection of deeper layers of the
epidermis, the fibrillary structures become finer and
shorter, covering the entire surface of the arthroconidium,
which then shows a flat morphology. This
would increase the contact surface with the tissue
making greater adhesion and acquisition of nutrients
possible. The authors report that, in addition to adhesion
to the stratum corneum, these fibrillary structures
make the connection between adjacent arthroconidia
possible, suggesting the formation of a more
