| The action of five acaricides was evaluated on eggs, larvae, nymphs and adults of the ixodid tick Rhipicephalus sanguineus. The acaricides tested were: high cis-cypermethrin (0.01%) + DDVP (0.11%), coumaphos (0.05%), deltamethrin (0.0025%), amitraz (0.025%) and cypermethrin (0.015%). Eggs treated with high cis-cypermethrin and cypermethrin showed eclosion inhibitions of 72.1% and 67.3%, respectively, whereas coumaphos was much less effective (only 11.7%). Except for coumaphos, which resulted in 63.3% and 80.0% mortality of nymphs and unfed females, respectively, all compounds tested killed 100% of all tick stages to which they were exposed. |

| The objective of the present study was to evaluate parasitemia and packed cell volume patterns of dogs experimentally inoculated with two isolates of Babesia canis: one from Belo Horizonte (BH) and the other from Lavras (Lv), Minas Gerais State, Brazil. Both isolates showed similar patterns, with the peak of parasitemia occurring three days post-infection. From the fourth day, parasitemia was detected in low levels (0.01%) with small periodical increases. The packed cell volume decreased after the parasitemia beginning, with oscillations during the experimental period. All dogs remained apparently normal, except one, which had been inoculated with the BH isolate and presented classical clinical signs of babesiosis (weakness, anemia, hemoglobinuria and... |

| The sanitary conditions of 13 animal houses in nine public institutions in Minas Gerais, and the presence of endo and ectoparasites of mice and rats colonies kept in these facilities were evaluated. Data about barriers to prevent the transmission of diseases and a program of sanitary monitoring were obtained through a questionnaire and local visit. Parasitological methods were performed for diagnosing mite, lice, helminthes, and protozoa parasites in 344 mice and 111 rats. Data have shown that the majority of the animal houses had neither proper physical environment nor protection barriers to prevent the transmission of infections. Parasitological results have shown that only one animal house (7.7%) had parasite free animals, whereas the others have... |
