The microflora associated to furuncular lesions, larvae and
pupae of Dermatobia hominis, as well as the relationships
between parasite, host and microflora associated, as a
comprehensive microsystem, has been studied. One hundred and two
furuncular myiasis due to D. hominis larvae in several
breeds of cattle were studied and the following bacterial species
were significant: Staphylococcus aureus, S. epidermidis, S.
warneri, Bacillus subtilis and Escherichia coli.
Closely related, the microflora associated to 141 samples from
first, second, third instar larva and both external surface and
larval cavities has been studied. The representative associated
microflora to the larvae were: S. aureus, B. subtilis, S.
hycus and Moraxella phenylpiruvica, Moerella
wisconsiensis, Proteus mirabilis and P. vulgaris, M.
phenylpiruvica, M. wisconsiensis, P. mirabilis and P.
rettgeri were the representative microflora associated to 64
pupae of D. hominis.
