Studies on transmissibility of a tissue-culture-modified laryngotracheitis virus.
The spreading characteristic of a tissue-culture-modified laryngotracheitis virus (LTV) was demonstrated in chickens under both laboratory and field conditions. An enzyme-linked immunosorbent assay was used to measure serum antibodies to LTV in experimental chickens. Contact controls developed immunity comparable to that of vaccinates and were able to resist challenge with a virulent LTV inoculated into the infraorbital sinus.
