Eradication of murine typhus fever in a rural area: preliminary report.

An attempt to eradicate murine typhus fever by control of rats and rat-fleas in rural foci was carried out in Georgia between July 1953 and May 1954. Anticoagulant rat poisons and DDT powder were the principal agents used. Rats were eliminated from 89% of rat-infested premises and satisfactory flea reduction was achieved.Although premises cleared of rats have become reinfested at a rate of 25% 10-18 months after clearance, typhus fever has apparently been eliminated. On the results reported, the authors believe that eradication of murine typhus fever from rural areas is economically and practically feasible, and that plague in commensal rats may also be eliminated by measures similar to those adopted in this experiment.

Rodenticides in bubonic-plague control.

The relatively recent development of more-effective pulicides has been paralleled by the discovery of more-efficient rodenticides. Eight of the latter-namely, warfarin, pival, red squill, alpha-naphthylthiourea (ANTU), zinc phosphide, arsenic trioxide, thallium sulfate, and sodium fluoroacetate (1080)-are discussed with particular reference to the criteria of effectiveness against rodents and relative safety to humans and pets. Although the perfect rodenticide has not yet been found, the authors consider that, at present, warfarin appears the most successful in domestic-rat control campaigns. However, the true value of warfarin has still to be determined, and in the meantime it is necessary to select the rodenticide and bait which appear to be most appropriate in each case. In addition, the authors point out that, if the initial poisoning has been ineffective, follow-up with a second rodenticide and bait can produce good results.
