ИЗУЧЕНИЕ ПАТОГЕННЫХ СВОЙСТВ ПОЛЕВЫХ ИЗОЛЯТОВ АДЕНОВИРУСОВ КУР, ВЫДЕЛЕННЫХ НА ТЕРРИТОРИИ РОССИЙСКОЙ ФЕДЕРАЦИИ
Abstract
Three day-old SPF chickens were intramuscularly infected with field chicken adenovirus isolates. PA-01,
Tbilissky and Kirovogradsky isolates werw found to be the most pathogenic for chickens. Bashkirsky isolate
was moderately pathogenic and was capable to replicate in SPF chickens without causing their death.
Ravis-Sosnovsky and VD-20 isolates were pathogenic for SPF chicks but their pathogenicity gradually decreased
during the subsequent passaging. However, these isolates did not induce any clinical signs associated
with the disease in Brown Highsex cross chickens i.e. they were nonpathogenic.
