National individual identification of horses.

Methods of equine identification including signalment, blood typing tattooing and freeze marking are discussed. A new system of individually identifying horses with an unalterable freeze mark is proposed. Unalterable numerical and alphabetical symbols have been developed to apply a registration number to the animal.

Nonlethal experimental inoculation of Columbia black-tailed deer (Odocoileus hemionus columbianus) with virus of epizootic hemorrhagic deer disease.

Intramuscular or intravenous inoculation of 5 Columbia black-tailed deer (Odocoileus hemionus columbianus) with virus of epizootic hemorrhagic deer disease (EHD) did not produce overt clinical disease. Two white-tailed deer (Odocoileus virginianus) exposed identically died in 5 to 6 days. There were no significant lesions in 1 black-tailed deer euthanatized on postinoculation day 5. The EHd virus was not isolated from the spleen of that deer. Seroconversion occurred in black-tailed deer, from zero EHD virus antibody titer before inoculation to titers of 1:128 to 1:256 after inoculation.

Ataxia, depression, and dermatitis associated with the use of dichlorvos-impregnated collars in the laboratory cat.

Ataxia and depression developed in 21 of 50 (42%) laboratory cats wearing flea collars impregnated with 2,2-dichlorovinyl dimethyl phosphate (dichlorvos or DDVP) in a warm dry environment. Five (10%) of the cats died. Whole blood cholinesterase (ChE) activity was significantly (P smaller than 0.001) reduced in all cats and cervical dermatitis occurred in 37 (74%) of them.
