Article
Full-text available
High mortalities of redclaw crayfish (Cherax quadricarinatus) were reported from northern Queensland farms, mainly attributed to two viruses, Chequa iflavirus and Athtab bunyavirus. From a research population of redclaw crayfish with these pre-existing viral infections, five individuals were found uninfected by Chequa iflavirus but infected with At...
Article
Cherax reovirus infects redclaw crayfish (Cherax quadricarinatus) and it may be involved in mortalities between 5-20% and stunting of up to 40% of survivors. The sequence of the RNA-dependent RNA polymerase was used to develop a reverse transcription, quantitative, PCR (RT-qPCR) which was specific against seven other crustacean viruses (Athtab bunyav...
Article
Studies on the prevalence of infection by Dirofilaria immitis in Australian cats are rare. The current study aimed to determine the prevalence of infection with D. immitis in a tropical region of Australia by antigen, antibody and PCR testing. 172 healthy cats over 6 months of age from the Townsville region of Australia were tested for D. immitis s...
Article
The first molecular evidence for natural, in ovo, vertical transmission of Chequa iflavirus and Athtab bunyavirus from farmed female redclaw crayfish (Cherax quadricarinatus) cultured in northern Queensland, Australia is presented. Cherax reovirus was also examined, but evidence that this is spread via in ovo vertically transmission is very limited...
Article
Full-text available
The impact of a range of different threats has resulted in the listing of six out of seven sea turtle species on the IUCN Red List of endangered species. Disease risk analysis (DRA) tools are designed to provide objective, repeatable and documented assessment of the disease risks for a population and measures to reduce these risks through managemen...
Article
Reoviruses have been isolated from many aquatic animals including fish and crustaceans. Viral inclusion bodies of reovirus have been found in the cytoplasm of the hepatopancreatic cells of redclaw crayfish (Cherax quadricarinatus). In the past, reverse transcription polymerase chain reaction (RT-PCR) designed from across other hosts was attempted t...

Objective Dirofilaria immitis commonly infects Australian dogs. Studies on the prevalence of infection by this parasitic helminth in Australia cats are rare and relatively old. Data obtained from other countries would suggest a likely prevalence of 4.7–16%. The current study aimed to determine the prevalence of D. immitis in an endemic region of Au...
Article
A Coxiella sp. closely related to the agent of Q‐fever, Coxiella burnetii, has been associated with mortalities in redclaw crayfish, (Cherax quadricarinatus), in farms and experimental facilities for three decades. Limited sequence data including 16S rRNA have placed the rickettsial species as a new species, candidatus Coxiella cheraxi closely rela...

Article
Chequa iflavirus is associated with mortalites reaching 20–40% after about three weeks following a stress event in farmed redclaw crayfish (Cherax quadricarinatus). Farmers need cost-effective interventions that can reduce the impact of this virus. This study was to identify strategies that would reduce the viral copy number as measured by reverse...
Article
Athtabvirus, a bunya-like virus and chequa iflavirus infect redclaw crayfish (Cherax quadricarinatus) and they may cause mortality reaching 20-40% after about three weeks following transportation stress. Lesions were seen in the muscles of broodstock and juveniles and nerve cords of craylings. Using NextGen sequencing, the whole transcriptomes of a...
Article
Chequa iflavirus (+ve sense ssRNA virus) infects redclaw crayfish (Cherax quadricarinatus) and it may cause mortality reaching 20-40% after about three weeks following stress. The sequence of the RNA-dependent RNA polymerase at nucleotide position 8383-9873 was used for developing and comparing PCR-based detection protocols. The reverse transcripti...
Article
Chequa iflavirus and a bunya-like virus infect redclaw crayfish (Cherax quadricarinatus) and they may cause mortality reaching 20-40% after about three weeks after a stress event. To complete River's postulates for viruses, virus-free animals are needed. Due to a lack of chequa iflavirus and bunya-like virus-free crayfish (testing shows >85% infect...
Article
In 2014, northern Queensland crayfish from farms affected by particularly transportation and translocation stress, started to die with mortality reaching 20–40% after about three weeks and then mortalities subsided. Crayfish from 1 farm had 65% mortalities within 11 weeks. With histological examination of broodstock and juveniles, the muscle fibres...
Article
Mosquito cell lines (C6/36) were reported in the literature to support the propagation of Penaeus monodon hepandensovirus (PmoHDV). We aim to evaluate the susceptibility and viral propagation of P. merguiensis hepandensovirus (PmeHDV) which is ∼22% different to PmoHDV in Aedes albopictus cell line (C6/36). Cellular changes in the infected cell cult...
Chapter
As the first step of bacteriophage infection, understanding the mechanics of adsorption of phages is vital for successful therapeutic phage treatments. It is also important for efficient scale-up of phages for industrial applications. It was understood early on that bacteriophage required divalent cations for successful adsorption. The mechanics of...
Article
In 1999, the causative agent of an epizootic in Cherax quadricarinatus was described, and given the provisional name Cherax quadricarinatus parvovirus-like. Sequencing of the 6334nt genome identified three open-reading frames on the top strand coding NS3 (35.55kDa), NS1 (67.36kDa) and NS2 (35.18kDa) and on the bottom strand a single open reading fr...
Article
Burkholderia pseudomallei is a saprophytic bacterium that causes melioidosis and is often isolated from rice fields in Southeast Asia, where the infection incidence is high among rice field workers. The aim of this study was to investigate the relationship between this bacterium and rice through growth experiments where the effect of colonization o...
Article
Aquatic animals can often undergo substantial physiological responses to salinity; however, associated lipid/fatty acid alterations to their various tissues have received little attention. To investigate this, we measured the growth of mud crab, Scylla serrata, juveniles over two moults (duration of 23-60 days) at salinities of 4, 12, 20, 28, 36 an...

Full-text available
Nine endogenous Brevidensovirus-like elements (EBreVE) were identified in redclaw freshwater crayfish Cherax quadricarinatus from different sources suggesting that these elements are widespread in redclaw in northern Queensland, Australia. These endogenous virus-like elements shared nucleotide identities (70–100%) and amino acid similarities (34–10...

Previously designed endpoint PCR has been adapted for use with real time PCR to detect the presence of Salmonella typhimurium and Salmonella enteritidis in fish. Optimization of a standard curve in the presence of herring sperm DNA as background matrix indicated that the real time PCR highly efficient with the Pearson coefficient of determination (...
Article
Aims: To investigate the presence of prophage in Streptococcus iniae, a highly problematic fish pathogen. Methods and results: Cross-spotting assays and mitomycin C inductions were conducted to screen for prophage in 48 Strep. iniae isolates. Bacteriophages were characterized by plaque assays, transmission electron microscopy and DNA restriction...
Article
The adenine methyltransferase (DAM) gene methylates GATC sequences that have been demonstrated in various bacteria to be a powerful gene regulator functioning as an epigenetic switch, particularly with virulence gene regulation. However, overproduction of DAM can lead to mutations, giving rise to variability that may be important for adaptation to...
Article
Hepatopancreatic parvovirus infection is associated with reduced growth rates of prawns during the juvenile stages and overt mortalities. Hepatopancreatic parvovirus was purified from Penaeus merguiensis from northern Queensland and a partial consensus sequence of 5.9 kb was obtained. Nucleotide comparisons revealed that the Australian isolate of H...
