Abstract
Four North Island brown kiwis and six lesser short-tailed bats were inoculated intramuscularly with 300 000 rabbit lethal doses of rabbit haemorrhagic disease (RHD) virus. No clinical abnormalities were observed in the kiwis and bats throughout the study period. Although no viraemia was detected in any of the kiwis, all four birds produced a serological response to RHD virus above the positive cut-off by 14 days after inoculation, and in two of the birds, antibodies persisted for over 5 months. Two kiwis were killed 48 days after inoculation. Their tissues were examined for lesions, and for the presence of persistent virus by both reverse transcription polymerase chain reaction and by inoculation of tissue suspensions into rabbits. No gross or histological lesions suggestive of a viral infection were detected and tests for detection of virus were negative. The serological response in the kiwis was probably due to the birds responding to viral antigen in the inoculum rather than to multiplication of the virus. None of the bats showed a serological response to RHD virus above the positive cut-off by 14 days after inoculation and the results of the pathological and virological examinations were negative.

Abstract
Infection of cells with classical swine fever virus (CSFV) is mediated by the interaction of envelope glycoproteins E2 and Erns with receptor molecules on the cell surface. These proteins are also the major antigens for eliciting neutralizing antibodies and conferring protective immunity. Here we report the identification of multiple neutralizing epitopes on these proteins by screening a phage-displayed random peptide library with CSFV-specific neutralizing monoclonal antibodies. Two different E2-specific neutralizing mAbs (a18 and 24/10) were found to bind to a common motif SPTxL, which is similar to the sequence SPTTL of the E2 protein (aa 289-293), indicating that this is likely to be an immunodominant epitope. Similarly, an immunodominant epitope corresponding to the sequence DKN of Erns (aa 117-119) was identified for two independent Erns-specific neutralizing antibodies, b4-22 and 24/16, respectively. Another binding motif, CxNNxTC, was identified for mAb 24/16, but not for b4-22. Sequencing analysis of the genes coding for the light chain of these mAbs was conducted to ensure that all mAbs were derived from different hybridomas, rather than from different subclones of a common parent line. Inhibition studies using immunofluorescent antibody assay and virus neutralization test demonstrated that the mimotope peptides truly mimicked the antibody binding determinants on the viral proteins. The detailed mapping data for these neutralizing epitopes will be useful for development of improved diagnostic tests and perhaps a peptide-based vaccine for this important swine disease.

Abstract
Nipah virus, family Paramyxoviridae, caused disease in pigs and humans in peninsular Malaysia in 1998-99. Because Nipah virus appears closely related to Hendra virus, wildlife surveillance focused primarily on pteropid bats (suborder Megachiroptera), a natural host of Hendra virus in Australia. We collected 324 bats from 14 species on peninsular Malaysia. Neutralizing antibodies to Nipah virus were demonstrated in five species, suggesting widespread infection in bat populations in peninsular Malaysia.

Abstract
A polymerase chain reaction (PCR) method for the detection of duck virus enteritis (DVE) virus in tissues of infected and affected ducks, and in cell culture was developed. This required us to obtain specific nucleotide sequence information as we could not find any specific data about the genome of the virus. We found the assay to be highly effective in detecting the virus under experimental conditions and to be easily transferred to laboratories in Vietnam where it is being used in studies on the epidemiology of the disease. We have applied this simple and rapid diagnostic method to the detection of DVE isolates grown in cell culture and tissues from infected birds. The assay was also able to differentiate DVE from other avian herpesviruses, such as Marek's disease, infectious laryngotracheitis virus and goose herpesvirus.

Abstract
The complete nucleotide sequence of the Czech strain of rabbit haemorrhagic disease virus (RHDV) was determined to be 7437 nucleotides in length with a 5-terminal non-coding region of 9 nucleotides and a 3'-terminal non-coding region of 59 nucleotides. Two open reading frames (ORFs) were found within this sequence coding for polypeptides of 2344 (nucleotides 10-7044) and 117 amino acids (nucleotides 7025-7378). The sequence of this isolate was approximately 1% different from that reported by Meyers et al., having 78 nucleotide changes which resulted in 30 amino acid differences, the majority of these clustering in the N-terminus of the large ORF and the middle of the viral coat protein. Only a single conservative amino acid change was seen in the smaller 3'-terminal ORF. Since the virus cannot at present be propagated in tissue culture, but isolated only after replication in rabbits, the reported sequence must be considered as a consensus sequence from the viral population. To gain some understanding of the possible sequence diversity within this virus population, 97 clones were sequenced from a polymerase chain reaction (PCR) fragment to determine the sequence diversity of the virus population. Four major classes of variant were described with mutations generally in the third base position of codons. A nested reverse transcriptase (RT) PCR (using sequence derived for the coat protein of RHDV) was used to determine the presence or absence of RHDV inoculated into non-host animal species. No replication of the virus was detected in 28 different vertebrate species other than rabbits. PCR tests on both mosquitoes and fleas feeding on RHDV infected rabbits were positive. The RT-PCR test was more sensitive when compared with an antigen capture ELISA to detect the presence of genomic RNA/or virus in infected rabbits.

Abstract
An antigen-capture ELISA was used to detect hog cholera virus (HCV) antigens in blood and tissues taken from pigs infected with 2 different strains of virus. Specific antigens were demonstrated in peripheral blood leucocytes (PBLs) and a wide range of tissue samples 4-6 days after infection of pigs with a moderate-high virulent HCV strain (Weybridge virus). Strong signal to noise (S/N) ratios were obtained in the ELISA for PBLs and lymphoid tissues such as spleen, tonsil and mesenteric lymph nodes at 5-7 days after infection with the Weybridge virus, S/N ratios varying between 8.1-19.7 for blood samples and 4.3-19.1 for spleen samples. High positive ELISA results were also obtained for duodenum and ileum samples (S/N ratios 10.3-18.6) taken from these pigs, reflecting severe pathological changes observed in the gut at post mortem. In contrast, the antigen-capture ELISA gave strong positive results for PBLs and spleen samples only at 7-9 days after infection of pigs with a low virulent strain of HCV (New South Wales virus). The ELISA S/N ratios averaged 9.5 for PBLs and 8.9 for spleen samples in these animals. Although virus isolation detected infection earlier in the infected pigs, the ELISA returned positive results on PBLs and spleen samples around the time all of the animals first showed typical signs of classical swine fever. The technique does not require tissue culture and takes less than 36 h to return a definitive result.
