Abstract

SANTOS, Rosella de Oliveira et al. Use of tetraethiltyuram in the treatment of ectoparasites in mice. Rev. Saúde Pública [online]. 1988, vol.22, n.1, pp. 41-45. ISSN 0034-8910.  http://dx.doi.org/10.1590/S0034-89101988000100006.

Colonies of CBA, C57BL/10, BALB/c and Swiss mice housed in conventional systems were found to be infected to different degrees with both Myobia musculi and Myocoptes musculinus. Groups of ten different sister-brother pairs of the isogenic mice and groups of 25 mice separated according to were infected by the parasite and then submitted to 4 different schemes of treatment with Tetmosol. C57BL/10 presented a very low incidence of parasites (1.2%). Every pair of CBA, and every Swiss mice examined, were found to be infected while only 50-90% of the pairs of BALB/c mice were infected. The best results of four different schemes were obtained by dipping the animals in 2.5% Tetmosol, at 3-4 days intervals for 21 days. The incidence of adult parasite forms in CBA, BALB/c and Swiss mice were found to be 0%, 40% and 0%, respectively, while in viable eggs it was found to be 20%, 50% and 0%, respectively.
