Resumen:
Here, we review the human botfly (Dermatobia hominis), which belongs to
a group of Diptera generically known as ``myiasis-causing flies,''
characterized by the ability of their larvae to develop in animal flesh.
In addition to its medical and economic importance, there is an academic
interest in this botfly because of its peculiar biology, particularly
because a phoretic diptera is needed to complete the life cycle. The
larvae penetrate the host's skin, causing furuncle-like lesions that are
pruritic, painful, and resemble subcutaneous nodules, producing
irreversible perforations in the skin. Although D. hominis is
distributed from Mexico to Argentina, a review performed by our working
group from 1999 to 2015 determined that the countries with the highest
infection rates in travelers are Belize, Bolivia, and Brazil.
Interestingly, infected men show a higher variation in the distribution
of the lesions than in women. Many treatment schemes have been
suggested, including the application of highly dense liquids to the
lesion to cause anoxia in the D. hominis larvae. We showed, for the
first time, a Bayesian inference between D. hominis and other
myiasis-causing flies. The flies grouped into two main clusters
according to their capacity to produce facultative and obligatory
myiasis, and D. hominis was phylogenetically close to Cuterebra spp.
