Abstract:
Bacterial diseases of the gills of commercially reared salmonids in freshwater are common problems. They accounted for 18% of all diagnostic submissions to the Atlantic Veterinary College from commercial fish hatcheries. Definitive diagnosis is difficult because of the growth characteristics of the putative bacteria in culture. Research into the pathogenesis of these diseases has also been similarly limited. Monoclonal antibodies (MAbs) were developed to 2 globally significant gill bacterial pathogens, Flavobacterium branchiophilum, the causative agent of bacterial gill disease, and Cytophaga

Abstract:
Epidemic mortalities of chinook salmon alevins (Oncorhynchus tshawytscha) have occurred annually at a freshwater hatchery at the Chehalis River, British Columbia, Canada, since 1982. Previous work has identified branchial epithelial hyperplasia as the predominant pathological change. Our initial work lead us to test the hypothesis that Chehalis River disease (CRD) was actually a novel form of bacterial gill disease (BGD). Histological and ultrastructural observations indicated that CRD-affected gills harboured a bacterial biofilm apparently complexed with particulate iron prior to and during c

Abstract:
Amoebic gill disease is a parasitic condition that commonly affects marine farmed Atlantic salmon. The causative agent, Neoparamoeba perurans, induces a marked proliferation of the gill mucosa and focal superficial necrosis upon branchial lesions. The effect that amoebic branchialitis has upon gill associated commensal bacteria is unknown. A 16S rRNA sequencing approach was employed to profile changes in bacterial community composition, within amoebic gill disease (AGD)-affected and non-affected gill tissue. The bacterial diversity of biopsies with and without diseased tissue was significantly

Abstract:
Branchial surfaces of finfish species contain a microbial layer rich in commensal bacteria which can provide protection through competitive colonization and production of antimicrobial products. Upon disturbance or compromise, pathogenic microbiota may opportunistically infiltrate this protective barrier and initiate disease. Amoebic gill disease (AGD) is a globally significant health condition affecting salmonid mariculture. The current study examined whether altering the diversity and/or abundance of branchial bacteria could influence the development of experimentally induced AGD. Here, we c

Agaricus bisporus sporocarps exhibiting characteristic 'drippy gill' symptoms from a natural outbreak were examined. Discrete bacterial droplets on the hymenial lamellae often coalesced to form ribbons of bacterial ooze. Longitudinal splits on the stipe were lined with a similar bacterial ooze. Bacteria isolated from both the hymenium and stipe were identified as Pseudomonas agarici, and were confirmed to be the causal organism by satisfying Koch's postulates. By light and transmission electron microscopy, the causal bacteria were found to colonize the extrahyphal spaces and degrade the extrac

Abstract:
The expansion of aquaculture necessitates innovative disease detection methods to ensure sustainable production. Fish diseases caused by bacteria, viruses, fungi, and parasites result in significant economic losses and threaten food security. Traditional detection methods are labor-intensive and time-consuming, emphasizing the need for automated approaches. This study investigates the application of convolutional neural networks (CNNs) for classifying freshwater fish diseases. Such CNNs offer an efficient and automated solution for fish disease detection, reducing the burden on aquatic health

Abstract:
The main priority in the breeding goal of the recently established Tasmanian Atlantic salmon selective breeding program is for resistance to amoebic gill disease (AGD), which is caused by the marine ectoparasite Neoparamoeba perurans and is characterised by hyperplastic changes to the gill tissue. A categorical gross 'gill score' is used to schedule freshwater bath treatments. Bathing and direct production losses to AGD are estimated to add over 20% to the cost of production. The purpose of this thesis was to (i) investigate whether genetic variation of resistance to AGD exists (ii) determine

Amoebic gill disease (AGD) is the single most significant disease affecting Tasmanian marine salmonid farming. The current treatment of AGD is freshwater bathing affected sea-caged fish. However, this current method of treatment is becoming less effective with an apparent increase in bathing frequency over the years fuelling a rise in production costs to the Tasmanian Atlantic salmon industry.

Spiders, scorpions, ticks, and mites are usually mistaken for insects, just as horseshoe crabs are misidentified as crustaceans. The biological and commercial importance of chelicerates cannot be overstated; members represent vectors of devastating animal and plant diseases (acarids), wielders of poisons and venoms (arachnids), and critical for the detection of bacterial contaminants in phar

The unusual behavior of cleaner fish has attracted both popular and scientific curiosity since its discovery early in the 20th century. These fish apparently make their living by removing external parasites from “host” fishes of other species (some also remove bacteria or diseased and injured tissue). When they approach cleaners, hosts assume an unusual motionless posture that allows cleaners to feed from their scales, from their gill cavities, or even inside their mouths. For their trouble, cleaner fish get a meal, and hosts get a good cleaning. The interaction between cleaner fish and their
