Has Epizootic Become Enzootic? Evidence for a Fundamental Change in the Infection Dynamics of Highly Pathogenic Avian Influenza in Europe, 2021.
outbreaks that are part of the most recent autumn/winter 2021 epizootic, or (ii) further virus variants were reintroduced by migratory birds, and these two sources of reintroduction have driven the HPAI ...
A liquid bead array for the identification and characterization of fljB-positive and fljB-negative monophasic variants of Salmonella Typhimurium.
required. In addition, identification of the mutations affecting expression of the flagellar gene fljB can be useful to support the monophasic character observed phenotypically. Finally, genetic subtyping of ...
Motif co-regulation and co-operativity are common mechanisms in transcriptional, post-transcriptional and post-translational regulation.
by simple sequence motifs in the regulatory segments of genes and (pre-)mRNAs, and in the intrinsically disordered regions of proteins. Although these regulatory modules are physicochemically distinct, ...
Overexpression of DosR in Mycobacterium tuberculosis does not affect aerobic replication in vitro or in murine macrophages
7H9 culture medium, and for its capacity to replicate in murine macrophages. Under aerobic conditions, hsp60-driven DosR significantly induced the expression of 39 out of 44 DosR regulon genes, as ...
The combination of attenuated Newcastle disease (ND) vaccine with rHVT-ND vaccine at 1 day old is more protective against ND virus challenge than when combined with inactivated ND vaccine.
herpesvirus of turkeys expressing the F gene of ND virus (rHVT- ND) and live ND vaccine at 1-day-old was compared with a classical programme that included a conventional live and an inactivated ND vaccine at ...
