Synthetic T7-driven cDNA minigenomes containing the bacterial chloramphenicol acetyltransferase gene as a reporter were derived from the genome of two salmonid novirhabdoviruses, infectious haematopoietic necrosis virus (IHNV) and viral haemorrhagic septicaemia virus (VHSV). We showed that an exogenous IHNV RNA minigenome transfected into fish cells could be rescued following IHNV infection as ...
A number of viral haemorrhagic septicaemia (VHS) virus isolates of European marine origin were shown to be of low pathogenicity or non-pathogenic to Atlantic salmon parr by water-borne infection. A reference freshwater VHS virus isolate known to be highly pathogenic to rainbow trout was also of low pathogenicity to Atlantic salmon. Virus was detected in some mortalities, however, demonstrating ...
Sequence analysis of a 795 nucleotide region of the fish rhabdovirus viral haemorrhagic septicaemia virus (VHSV) genome revealed one complete and one partial ORF of 369 and 153 nucleotides, respectively. The latter ORF probably encodes the amino-terminal part of the L (polymerase) protein. The former ORF potentially encodes a 122 amino acid protein. The location of this ORF as well as the size ...
Serotype B of Pasteurella multocida is a major agent of haemorrhagic septicaemia (HS), a form of blood poisoning widespread in cattle and buffalo from Southern Asia. The vaccines currently used against the disease are not potent enough, being effective only for a limited duration only. In an attempt to identify immunogenic components of P. multocida for use as live/subunit vaccines, the outer m...
Genome wide host gene expression analysis in mice experimentally infected with Pasteurella multocida
Pasteurella multocida causes acute septicemic and respiratory diseases, including haemorrhagic septicaemia, in cattle and buffalo with case fatality of 100%. In the present study, mice were infected with P. multocida (1.6 × 103 cfu, intraperitoneal) to evaluate host gene expression profile at early and late stages of infection using high throughput microarray transcriptome analyses. Several dif...
Swiss aquaculture farms were assessed according to their risk of acquiring or spreading viral haemorrhagic septicaemia (VHS) and infectious haematopoietic necrosis (IHN). Risk factors for the introduction and spread of VHS and IHN were defined and assessed using published data and expert opinions. Among the 357 aquaculture farms identified in Switzerland, 49.3% were categorised as high risk, 49...
Pasteurella septica is a common pathogen of animals and birds, generally causing a haemorrhagic septicaemia, and it has been described as an upper respiratory tract commensal organism in cats, rats, and dogs. Human infection has been reported on several occasions following the bites of cats, the first recorded case being that of Kapel and Holm (1930), and occasionally from the bites of other an...
To evaluate the genetic diversity of viral haemorrhagic septicaemia virus (VHSV), the sequence of the glycoprotein genes (G) of 11 North American and European isolates were determined. Comparison with the G protein of representative members of the family Rhabdoviridae suggested that VHSV was a different virus species from infectious haemorrhagic necrosis virus (IHNV) and Hirame rhabdovirus (HIR...
