Assessing the Seroprevalence Against Avian Pneumovirus and Ornithobacterium rhinotracheale in Broilers in Uruguay
The objective of this study was to estimate the true prevalence of individual chickens serologically test-positive against avian pneumovirus and Ornithobacterium rhinotracheale in Uruguay. Seventeen different broiler farms existed in three different provinces in Uruguay were recruited and the 1861 broilers were investigated. Individual-chicken sera were analyzed using a commercial enzyme-linked...
متن کاملVaccination of chickens against Ornithobacterium rhinotracheale infection.

متن کاملSeroprevalence and identification of Ornithobacterium rhinotracheale from broiler and broiler breeder flocks in Thailand.
Ornithobacteriosis is an infectious disease of avian species that has been reported in almost all countries around the world, except Thailand. The objectives of this study were to determine the seroprevalence of Ornithobacterium rhinotracheale (ORT) and to isolate and identify ORT in broilers and broiler breeders in Thailand. Chicken antibodies had been randomly checked from 17 farms (19 flocks...
متن کاملCo-infection of broilers with Ornithobacterium rhinotracheale and H9N2 avian influenza virus
BACKGROUND Since 2008, a progressive pneumonia has become prevalent in broilers and laying hens. This disease occurrs the first day after hatching and lasts more than 30 days, resulting in approximately 70% morbidity and 30% mortality in broilers. The objective of this study was to isolate and identify the pathogens that are responsible for the progressive pneumonia and establish an animal mode...
