Xenopsylla cheopis fleas, allowed to feed on laboratory rats injected with iron-59 citrate, retained the isotope tag from 10 to more than 20 days depending on their sex, exposure level, and subsequent blood meals. The loss of the marker from the rats' blood occurred at a predictable rate, and fleas were successfully tagged after exposure to blood containing as little as 0.22 µCi/ml. Female fleas were found to take larger blood meals than males and to lose the tag at a faster rate when starved. Radioactive fleas allowed to feed on a non injected host retained less of the isotope than those which were starved after exposure. |
