Abstract To determine the cause of an unprecedented outbreak encephalitis among horses in New South Wales, Australia, 2011, we performed genomic sequencing viruses isolated from affected and mosquitoes. Results showed that most cases were caused by a variant West Nile virus (WNV) strain, WNVNSW2011, is closely related to WNV Kunjin (WNVKUN), indigenous strain Australia. Studies mouse models for pathogenesis WNVNSW2011 substantially more neuroinvasive than prototype WNVKUN strain. In this...
Abstract During the 2007 equine influenza outbreak in Australia, respiratory disease dogs close contact with infected horses was noted; (H3N8) virus infection confirmed. Nucleotide sequence of from identical to that horses. No evidence dog-to-dog transmission or persistence found.
In mid-February 2015, a large number of deaths were observed in the sole extant population an endangered species freshwater snapping turtle, Myuchelys georgesi, coastal river New South Wales, Australia. Mortalities continued for approximately 7 weeks and affected mostly adult animals. More than 400 dead or dying animals surveys conducted after outbreak had ceased indicated that only very small proportion survived, severely threatening viability wild population. At necropsy, poor body...
During the equine influenza (EI) outbreak, respiratory disease was observed in dogs that were close proximity to infected horses. Investigations undertaken exclude virus infection. Of 23 seropositive tests using A/Sydney/2007 as test antigen, 10 showed clinical signs. EI appeared be readily transmitted held horses, but there no evidence of lateral transmission other did not have contact with or
Hendra virus occasionally causes severe disease in horses and humans. In Australia 2013, infection was detected a dog that had been contact with an infected horse. Abnormalities viral RNA were found the dog's kidney, brain, lymph nodes, spleen, liver. Dogs should be kept away from horses.
Cryptococcosis was diagnosed in seven ferrets (five from Australia; two western Canada) displaying a wide range of clinical signs. Two the lived together. One (5‐years‐old) had cryptococcal rhinitis and presented when infection spread to nasal bridge. Its sibling developed abscessation right retropharyngeal lymph node 12 months later, soon after developing severe skin condition. DNA fingerprinting microsatellite analysis demonstrated that strains isolated these siblings were...
To report the rapid transmission of bovine ephemeral fever (BEF) virus from north-western New South Wales south to Victorian border in January 2008 and present data that suggests an uncommon meteorological event caused this southward dispersal vectors.The locations reported clinical cases, sentinel herds results a survey cattle southern affected area were examined delineate distribution transmission. Synoptic weather charts for conditions may have favoured movement vectors southerly...
During the equine influenza (EI) outbreak, two assays were used in parallel to diagnose disease, demonstrate freedom from infection disease control zones and ultimately that EI virus had been eliminated Australian horse population. A longitudinal study of a population naturally infected horses was established determine performance characteristics these assays.
Objective To report the occurrence of an epizootic bovine ephemeral fever ( BEF ) in N ew S outh W ales NSW and northern V ictoria 2009–10 describe application a real‐time reverse transcription polymerase chain reaction qRT‐PCR assay during outbreak. Procedures Whole‐blood samples from animals exhibiting clinical signs were requested district veterinarians . In addition, submitted private practitioners ictoria. , showing acute tested using assay. Serological testing for diagnosis was...
Infection of bulls with bovine viral diarrhoea virus (BVDV) can result in the development persistence, confined to reproductive tract. These develop a normal immune response high neutralizing antibody titres. However, BVDV be excreted semen for prolonged period. Although relatively rare, this study we describe six separate cases being prepared admission artificial breeding centres. Semen samples were tested pan-Pestivirus-reactive real-time PCR assay and RNA was detected from five three...
BLUETONGUE VIRUS SEROTYPE 16 DETECTION IN NSW: In coastal New South Wales (NSW), bluetongue virus (BTV) serotypes 1 and 21 are endemic transmitted in most years without evidence of disease. However, serotype (BTV-16) infection was detected for the first time NSW November 2016 cattle undergoing testing export. Retrospective blood samples collected from sentinel as part National Arbovirus Monitoring Program (NAMP) established that transmission BTV-16 occurred April on North Coast....
The emergence of Japanese encephalitis virus (JEV) in eastern Australia 2022 caused extensive reproductive disease pigs and is a threat to public health. Groups weaned piglets were experimentally infected with the Australian outbreak strain JEV (genotype 4). All challenged at 5 weeks age after an intradermal injection 1 × 105.5 (n = 4) or 104.5 TCID50/pig 5). Intranasal instillation was less effective this age, infecting 3/4 same higher dose 1/5 lower dose. Intradermal using 105.0 also 9/9...
Objective To determine if postweaning multisystemic wasting syndrome (PMWS) is occurring in the New South Wales pig population and to current past seroprevalence of porcine circovirus 2 (PCV2). Design Pig veterinarians were contacted seeking submission tissues from animals with clinical signs suggestive PMWS. Samples also accepted suspected cases dermatitis nephropathy (PDNS). Serological studies undertaken on archival sera submitted during study. Procedure Histopathological examination was...
