Avian reovirus infections.
Avian reoviruses are ubiquitous among poultry flocks. Although infection is usually present without disease, reoviruses may occasionally be involved in several disease syndromes of which viral arthritis/tenosynovitis in chickens is the most important, particularly in broiler breeds. While reoviruses have been isolated from turkeys and several other species of birds with various conditions, the ...
متن کاملProteomics Analysis of the DF-1 Chicken Fibroblasts Infected with Avian Reovirus Strain S1133
BACKGROUND Avian reovirus (ARV) is a member of the Orthoreovirus genus in the Reoviridae family. It is the etiological agent of several diseases, among which viral arthritis and malabsorption syndrome are the most commercially important, causing considerable economic losses in the poultry industry. Although a small but increasing number of reports have characterized some aspects of ARV infectio...
متن کاملApplying conserved peptides of NS1 Protein of avian influenza virus to differentiate infected from vaccinated chickens
Avian influenza (AI) is a highly contagious disease in poultry and outbreaks can have dramatic economic and health implications. For effective disease surveillance, rapid and sensitive assays are needed to detect antibodies against AI virus (AIV) proteins. In order to support eradication efforts of avian influenza (AI) infections in poultry, the implementation of “DIVA” vaccination strategies, ...
متن کاملComparative investigations of infectious runting and stunting syndrome in vaccinated breeder chicks by inactivated reovirus and chicks from non-vaccinated breeders
Reoviruses are important pathogens responsible for poor growth performance and silent losses in the poultry industry. They are associated with many disease and syndromes such as malabsorption (runting and stunting syndrome), respiratory diseases and immunosuppression. Broiler birds are most susceptible to viral infections during the early post hatching period. Therefore, the transfer of materna...

in the egg shells when the eggs were studied in UV-light (Fig. 1). Control eggs did not fluoresce. The concentration of oxytetracycline in the egg shell, albumen, and yolk was measured by UV-absorption spectrofluorometry (Hayes and DuBuy, 1964). Oxytetracycline was deposited mainly in the shell (0.182 ± 0.028 iig./gm., mean ± SD), and albumen (0.190 ± 0.030 !*g./gm.) whereas the yolk contained ...
