meadow mouse, wood rat, and the coyote have all been found suscepti- 
ble to tularemia in a fatal form. The extent to which other rodents, 
important fur-bearers, and predacious animals and such valuable game 
birds as grouse are susceptible to the disease is being investigated. 
Domestic rabbits also are susceptible under laboratory conditions, 
but no cases of tularemia have .yet been recognized in conmercial rab- 
bitries. Care should be exercised to avoid its introduction into 
such places. There is no danger of contracting tularemia from eating 
rabbit meat if it is thoroughly cooked, even though the animal may 
have been infected. 
PROTECTIVE MASURES: 
No protective vaccine has thus far been determined nor has 
any treatment with serum or drugs been fd~nd effective against tul- 
aremia, Care should be exercised when in the open to avoid so far as 
possible bites of deer flies, ticks, or other known carriers of the 
infection, particularly in an area where an epizootic of tularemia 
is known to exist. The use of rubber gloves when handling or 
dressing rabbits, or when skinning other animals that may be in- 
fected with the disease, in order to avoid contact with the blood 
or the visceral organs, is the best known protection against human 
infection. This is not an absolute protection, however, as skilled 
laboratory workers who maintain the most careful precautions when 
handling carcasses and entrails frequently become infected. The 
same precautions should be followed in handling fresh skins. It is 
unlikely that skins that have been thoroughly dried over a period 
of three or four weeks will continue to carry the infective organ- 
ism. One attack of tularemia confers immunity to man. Immunes, 
therefore, should be employed where possible in occupations involv- 
ing risk of infection. 
QUARANT INE: 
In many parts of the country there is much interest in liber- 
ating wild rabbits to restock hunting areas, and these animals have 
been obtained from States where tularemia is now known to have been 
prevalent periodically. Where such importation for restocking pur- 
poses appears desirable, it is important that effective quarantine 
be maintained to prevent introduction of diseased animals into lo- 
calities where tularemia is not present or in which there is no mani- 
festation of the disease in epizootic form. Present information in- 
dicates that maintenance of a quarantine of wild rabbits for at least 
ten days is an essential safeguard. Infected wild rabbits are likely 
to die within a period of five or six days, although they may not 
invariably do so. Rabbits that die after capture, during shipment, 
or while held in quarantine should be carefully examined by persons 
capable of recognizing tularemia or other diseases, in order that the 
exact cause of death may be diagnosed.
