| Summary: | Establishment of Babesia sp. in laboratory-reared mice from infections in field rats was attained in two experiments. In the first experiment, Babesia sp. parasitized blood from Rattus tanizumi collected in Cabanatuan City, Nueva Ecija was inoculated into Swiss albino mice. Infection was established in all mice. Percent parasitemia ranged from 0.44 percent to 1.55 percent with the highest parasitemia noted at about 16-22 days post-exposure. In the second experiment, Babesia sp. parasitized blood from R. tanizumi collected in Calamba, Laguna was inoculated into ICR-CRJ mice. Infection was established in four out of 10 mice. Infection was noted about 3-7 days post-exposure with less than 1 percent parasitemia. In the two experiments, the parasites were observed to be unhealthy and degenarate. This is probably because of having been introduced in a new host species. The parasites seem to be of the non-virulent type as the infection did not cause any visible ill/fatal effect on mice. |
