Effect of selected environmental treatments on the incidence of gross Marek's disease lesions in chickens. 1975

R F Lapen, and S G Kenzy

The effects of selected environmental treatments on the incidence of gross Marek's disease (MD) lesions in chickens contact exposed to MD virus were examined. Treatments were high levels of airborne decomposition products from chicken litter in the rearing environment, disinfectants applied to chickens and their environments, and formaldehyde fumigation of eggs and newly hatched chicks. There were no significant differences in the incidence of gross MD lesions when treated and untreated groups were compared.

D003408	Cresols	Any of three isomeric crystalline aromatic methylphenols, also known as hydroxytoluenes.
D004202	Disinfectants	Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed)	Biocide,Disinfectant,Biocides
