The African swine fever virus isolate Belgium 2018/1 shows high virulence in European wild boar.
the genotype II ASF virus isolate ‘Belgium 2018/1’ showed a highly virulent phenotype in European wild boar similar to parental viruses like Armenia 2007 and other previously characterized ASFV strains. ...
Infectious Bursal Disease: a complex host-pathogen interaction.
immunosuppression in the field situation. Although satisfactory protection may be provided by the induction of high neutralizing antibody titres, interference from parental antibodies with vaccination has become the ...
What's in a strain? Viral metagenomics identifies genetic variation and contaminating circoviruses in laboratory isolates of pigeon paramyxovirus type 1.
Notably, mutations that were previously associated with pathogenicity in chickens were identified as minor sequence variants in one parent laboratory strain. A phylogenetic analysis of the consensus PPMV-1 ...
Capsid proteins from field strains of foot-and-mouth disease virus confer a pathogenic phenotype in cattle on an attenuated, cell-culture-adapted virus
Volume 92, Issue 5, Number 1151 (2011) Abstract: Chimeric foot-and-mouth disease viruses (FMDV s) have been generated from plasmids containing full-length FMDV cDNAs and characterized. The parental virus ...
Intranasal DNA vaccination induces potent mucosal and systemic immune responses and cross-protective immunity against influenza viruses.
immunization with naked- DNA. Furthermore, intranasal DNA vaccination with HA from a given H5N1 virus elicited full protection against the parental strain and partial cross-protection against a distinct highly ...
The major portal of entry of koi herpesvirus in Cyprinus carpio is the skin.
and the FL BAC 136 LUC TK revertant strain, including a disrupted and a wild-type thymidine kinase (TK) locus, respectively. In vitro, the two recombinant strains replicated comparably to the parental ...
Point mutations in an infectious bovine viral diarrhoea virus type 2 cDNA transcript that yields an attenuated and protective viral progeny.
cells and led to viral multiplication (AvrII+ strain). In vitro, viral titres reached by the parental strain exceed those of the AvrII+ strain by more than one order of magnitude. The latter was clearly ...
Classical swine fever virus is genetically stable in vitro and in vivo.
infected cells was compared with its parental virus, the recombinant virus derived from an infectious cDNA clone of CSFV strain Alfort/187. This low mutation frequency observed both in vitro and in vivo ...
Widespread occurrence of the micro-organism Wolbachia in ants.
determination system would lead to various parent-offspring conflicts over optimal reproduction. A possible weakness of existing theory is that only interests of nuclear genes are properly accounted for. Yet, ...
