Two bacterial strains (DY05T and 47666-1) were isolated in Queensland, Australia, from diseased cultured crustaceans Panulirus ornatus Penaeus monodon, respectively. On the basis of 16S rRNA gene sequence identity, shown to belong Harveyi clade genus Vibrio. Multilocus analysis using five housekeeping genes (rpoA, pyrH, topA, ftsZ mreB) showed that form a monophyletic group with 94.4% concatenated identity closest species. DNA–DNA hybridization experiments DY05T 47666-1 had 76% DNA...
The type strain of Vibrio owensii (DY05) was isolated during an epizootic aquaculture-reared larvae (phyllosomas) the ornate spiny lobster (Panulirus ornatus). V. DY05 formally demonstrated to be etiological agent a disease causing rapid and reproducible larval mortality with pathologies similar those seen epizootics. Vectored challenge via aquaculture live feed organism Artemia (brine shrimp) caused consistent cumulative rates 84 89% after 72 h, in contrast variable immersion challenge....
With recent technologies making it possible for commercial scale closed life-cycle aquaculture production of spiny lobster (Panulirus ornatus) comes a strong impetus to further understand aspects health. The gut microbiome plays crucial role in host health, affecting growth, digestion, immune responses and pathogen resistance. Herein we characterise compare microbiomes across different developmental stages (6–7 days post-emergence [dpe], 52 dpe 13 months [mpe]) regions (foregut, midgut...
Vibrio owensii DY05 is a serious pathogen causing epizootics in the larviculture of ornate spiny lobster Panulirus ornatus. In present study multi-tiered probiotic screening strategy was used to identify combination capable protecting P. ornatus larvae (phyllosomas) from experimental V. infection. From pool more than 500 marine bacterial isolates, 91 showed definitive vitro antagonistic activity towards pathogen. Antagonistic candidates were shortlisted based on phylogeny, strength activity,...
Abstract Lobsters have an open circulatory system with haemolymph that contains microorganisms even in the healthy individuals. Understanding role of these becomes increasingly important particularly for diagnosis disease as closed life-cycle aquaculture spiny lobster Panulirus ornatus nears commercial reality. This study aimed to characterise responses cultured P . juveniles at control (28 °C) and elevated (34 temperatures. was assessed by measuring immune parameters (total granulocyte...
Abstract Background Cobia (Rachycentron canadum) is the only member of Rachycentridae family and exhibits considerable sexual dimorphism in growth rate. Sex determination teleosts has been a long-standing basic biological question, molecular mechanisms sex determination/differentiation cobia are completely unknown. Results Here, we reported 2 high-quality, chromosome-level annotated male female genomes with assembly sizes 586.51 Mb (contig/scaffold N50: 86.0 kb/24.3 Mb) 583.88 (79.9 kb/22.5...
Summary The development of efficient probiotic application protocols for use in marine larviculture relies on comprehensive understanding pathogen–probiont–host interactions. probiont combination P seudoalteromonas sp. PP 107 and V ibrio 05 provides additive protection against vectored owensii DY infection larvae (phyllosomas) ornate spiny lobster, anulirus ornatus . Here, fluorescently tagged strains were used to demonstrate niche specialization these probionts both the live feed vector...
Shell (cuticular) disease manifests in various forms and affects many crustaceans, including lobsters. Outbreaks of white leg (WLD) with distinct signs pereiopod tissue whitening death have been observed cultured larvae (phyllosomas) ornate spiny lobster Panulirus ornatus, eastern rock Sagmariasus verreauxi, slipper Thenus australiensis. This study aimed to characterise identify the causative agent WLD through morphological molecular (16S rRNA gene whole genome sequencing) analysis,...
Bdellovibrio and like organisms (BALOs) are Gram-negative obligate predators of other bacteria in a range environments. The recent discovery BALOs the circulatory system cultured spiny lobster P. ornatus warrants more investigation. We used combination co-culture agar broth assays transmission electron microscopy to show Halobacteriovorax sp. strain Hbv preyed upon model prey bacterium Vibrio Vib. haemolymph microbiome juvenile was characterised following injection phosphate buffered saline...
Abstract Background The RAFAU is a five-day rapid-access, multidisciplinary service including Medical, Physiotherapy and Occupational therapy. aim to improve biopsychosocial outcomes ultimately avoid hospital admission. It opened in May 2021 an expansion of provision has occurred since then based on ongoing evaluations. Methods Data was manually recorded each day from existing proforma Excel, allowing for analysis be done the dates 03/01/2023 22/05/2023. Results 202 attendances were...
In this study, genetic sex marker candidates from northern hemisphere Mugil cephalus were tested to see if they could be used a population originating south-east Queensland, Australia. As such, region of the follicle stimulating hormone receptor (fshr) gene was sequenced but did not contain previously published single nucleotide polymorphisms (SNPs). However, further screening fshr revealed promising candidate for Queensland M. cephalus, 1834 G>T, which accurate in 100% fish (excluding...
