Abstract

Avian leukosis virus (ALV) is associated with immune suppression, neoplasia, and reduced performance in chickens. In this study, two strains of ALV were isolated from Luxi gamecocks by DF-1 cell culture and identified by PCR, immunofluorescence assay, and sequencing of the viral genome. These strains were found to be novel recombinant viruses with nucleotide sequence identity of over 93.0% in the LTR and 94.4% in U3 to ALV-J, over 95.0% in the 5’UTR to ALV-C, over 93.4% in gp85 to ALV-B, and over 96.0% in gp37 to ALV-E. These results indicate that these two isolates are recombinants between ALV-J, ALV-C, ALV-E and ALV-B.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
