Amoebic gill disease (AGD), caused by the protozoan parasite Neoparamoeba perurans, is one of the most significant infectious diseases for Atlantic salmon (Salmo salar L.) mariculture. The present study investigated the humoral immune response (both local in gill mucus and systemic in serum) of farmed Atlantic salmon naturally infected with N. perurans in commercial sea pens, at two different stages of the disease and after freshwater treatment. Parameters analysed included activity of immune related enzymes (i...

The Norwegian aquaculture of Atlantic salmon (Salmo salar L.) is hampered by ulcerative disorders associated with bacterial infections. Chronic ulceration may provide microenvironments that disturb the normal microbial biodiversity of external surfaces. Studying the composition of microbial communities in skin ulcers will enhance our understanding of ulcer aetiology. To achieve this, we tested marine farmed Atlantic salmon and sampled the base and edge of ulcers at the end of winter (April) and end of summer (September), in addition to skin mucus of healthy individuals...

This paper provides histological and ultrastructural data on Myxobolus mugchelo (Myxozoa), a parasite of the intestinal wall of thinlip mullet Liza ramada from the Comacchio lagoons (Northern Adriatic Sea, Italy). About 80% of the examined mullets were infected with this myxozoan. In histological sections, the plasmodia appeared rounded to ovoid and spindle shaped, measured 181.61 ± 97 × 122.79 ± 53.16 μm (mean ± standard deviation, SD) in size. Early sporogenic plasmodia were located primarily in the muscle layer where no pronounced inflammatory response was detected...

While recent studies have suggested that fish mucus microbiota play an important role in homeostasis and prevention of infections, very few studies have investigated the bacterial communities of gill mucus. We characterised the gill mucus bacterial communities of four butterflyfish species and although the bacterial diversity of gill mucus varied significantly between species, Shannon diversities were high (H = 3.7-5.7) in all species. Microbiota composition differed between butterflyfishes, with Chaetodon lunulatus and C...

Simon Gingins, Dominique G Roche, Redouan Bshary
Predatory reef fishes regularly visit mutualistic cleaner fish (Labroides dimidiatus) to get their ectoparasites removed but show no interest in eating them. The concept of compensated trait loss posits that characters can be lost if a mutualistic relationship reduces the need for a given trait. Thus, selective pressures on escape performance might have relaxed in L. dimidiatus due to its privileged relationship with predators. However, the cost of failing to escape a predatory strike is extreme even if predation events on cleaners are exceptionally rare...

Chronic Pseudomonas aeruginosa biofilm lung infection in cystic fibrosis patients is the best described biofilm infection in medicine. The initial focus can be the paranasal sinuses and then follows repeated colonization and infection of the lungs by aspiration. The matrix of the biofilms is dominated by alginate and the pathogenesis of tissue damage is immune complex-mediated chronic inflammation dominated by polymorphonuclear leukocytes and their products (DNA, oxygen radicals and proteases). The P. aeruginosa biofilm infection can be diagnosed by microscopy of lung tissue, sputum and mucus from the paranasal sinuses, where aggregates of the bacteria are found surrounded by the abundant alginate matrix...

How parasites recognize their definitive hosts is a mystery; however, parasitism is reportedly initiated by recognition of certain molecules on host surfaces. Fish ectoparasites make initial contact with their hosts at body surfaces, such as skin and gills, which are covered with mucosa that are similar to those of mammalian guts. Fish are among the most primitive vertebrates with immune systems that are equivalent to those in mammals, and they produce and secrete IgM into mucus. In this study, we showed that the monogenean parasite Heterobothrium okamotoi utilizes IgM to recognize its host, fugu Takifugu rubripes Oncomiracidia are infective larvae of H...

Integrated tilapia-pig farming, which uses manure from pigs as fertilizers in fish pond, is a traditional and common production system practised by small-scale farmers in South-east Asia. Although such systems may be environmentally sustainable, they also pose potential food safety hazards including transmission of faecal zoonotic pathogens and accumulation of antimicrobial and other chemical residues. This study aimed to determine differences in occurrence and characteristics of Salmonella spp. isolated from tilapia-pig and non-integrated aquaculture systems in Guangdong province, China...

Chemical communication is better understood in freshwater than marine fish. The Senegalese sole (Solea senegalensis) is a marine flatfish wherein one of the problems in aquaculture is the poor reproductive performance of hatchery-bred males. Is chemical communication involved in the reproduction of this species? Urine, intestinal fluid and mucus samples were taken from adult fish, wild-caught and hatchery-bred, over the spawning season (March to May), and assessed for olfactory potency using the electro-olfactogram (EOG)...

Nonlethal sampling techniques have previously been evaluated for detection of a variety of viral salmonid pathogens. However, many of these studies have used molecular assays in lieu of widely accepted cell culture techniques to evaluate the sampled tissues. Samples were collected from female steelhead Oncorhynchus mykiss broodstock using three potential nonlethal sampling methods (mucus/skin scrape, pectoral fin clip, and gill tissue biopsy) and evaluated for the presence of infectious hematopoietic necrosis virus (IHNV) via cell culture techniques...

A yeast was isolated from hypersaline sediments, grown and phylogenetically characterized as Sterigmatomyces halophilus strainN16. The dietary administration of this yeast was studied for its effect on skin mucosal immune and antioxidant status of gilthead seabream (Sparus aurata L.). Fish were fed a commercial diet (control, non-supplemented diet), or the same commercial diet supplemented with 0.55% or 1.1% of yeast for 15 and 30 days. One month after the end of the trial, fish from all treatments were intraperitoneally injected with pathogenic Vibrio parahaemolyticus and further fed with the same diets for one week, after which fish were also sampled...

Many species engage in mutualistic relationships with other species. The physiological mechanisms that affect the course of such social interactions are little understood. In the cleaning mutualism, cleaner fish Labroides dimidiatus do not always act cooperatively by eating ectoparasites, but sometimes cheat by taking bites of mucus from so-called "client" reef fish. The physiological mechanisms in these interspecific interactions, however, are little studied. Here, we focussed on three neuromodulator systems known to play important roles in intraspecific social behaviour of vertebrates to examine their role in clients' interspecific behaviour...
