Fully developed teleosts possess a highly immune system comprising both innate and adaptive elements, but when hatching from the egg, yolksac larva is still at an ontogenetically incomplete stage with regard to physiological, including immunological, functions. The in these young fish stages far less compared youngs appearing reptile avian eggs most mammals parturition. In those vertebrate groups early ontogenetic development of fetus protected. lack fully larvae critical, because this...
ABSTRACT In the past couple of decades, applications environmental nucleic acids (eDNA and eRNA) analysis methods have expanded rapidly into various research fields. Recently, World Organisation for Animal Health presented guidelines use eDNA as a biomonitoring tool disease surveillance in aquaculture. this paper, profile Yersinia ruckeri was monitored over course experimentally induced red mouth rainbow trout. Before after mortality started, fish pathogen burden, clinical signs, immune...
Abstract Background Digenean trematodes are parasitic platyhelminths that use several hosts in their life cycles and thereby embedded various ecosystems affected by local environmental conditions. Their presence a habitat will reflect the of different host species and, as such, they can serve ecological indicators. Only limited information on occurrence link to other trophic levels Danish freshwater is currently available.Therefore, main aim present study was increase our knowledge this...
As an environmental and industrial pollutant, cadmium (Cd) can cause a broad spectrum of toxicological effects. Multiple organs, especially the liver, are considerably affected by Cd in both humans animals. We investigated protective effects metallothionein (MT) vitamin E (VE) supplementation on Cd‐induced apoptosis grass carp ( Ctenopharyngodon idellus ) liver. Grass were divided into four groups: control group, + phosphate‐buffered saline (PBS) VE MT group. All fish injected with CdCl 2...
Single nucleotide polymorphisms (SNPs) on rainbow trout chromosomes Omy16 and Omy17 are associated with a lower parasitic load delayed-time-to-death following exposure to the ciliate Ichthyophthirius multifiliis causing white spot disease (WSD). We have evaluated application of two quantitative trait loci (QTL) represented by these SNPs for practical breeding purposes. Homozygous males served as parent fish securing offspring at least one allele (heterozygous homozygous fish) higher...
Flavobacterium psychrophilum is the causative agent of Bacterial Cold Water Disease (BCWD)/ Rainbow Trout Fry Syndrome (RTFS) in rainbow trout Oncorhynchus mykiss. The disease associated with significant mortality farms and thereby responsible for severe economical losses this part aquaculture industry. Vaccination very young life cycle stages not successful due to immature development adaptive immunity yolksac larvae early fry. This explains extensive usage antibiotics control BCWD/RTFS....
Abstract Aquaculture industries face challenges in fish production, primarily due to disease occurrence. Clinical manifestations of these diseases often indicate a considerable advancement the pathological process. Infected experience morbidity, leading compromised welfare and substantial economic losses for production facilities. Therefore, prophylaxis early detection pathogens could allow facility managers intervene or treat before clinical signs occur. For first time, environmental...
Cadmium (Cd) causes a broad spectrum of toxicological effects to animals. Aquatic animals were more likely accumulate Cd than terrestrial because the living environment. Clearance in aquatic has become an important part food safety. The present study was focused on oxidative damage induced by liver grass carp Ctenopharyngodon idellus and protective effect vitamin E (VE) metallothionein (MT). Grass divided into four groups: control group, Cd+phosphate-buffered saline (PBS) Cd+VE Cd+MT group....
The host-pathogen interactions are tripartite and include the host, pathogen, environment. For a long time, attention has mainly been addressed to host's immune mechanisms pathogen's virulence factors while environmental factor received less interest. About decade ago, studies on DNA (eDNA) started emerge as this approach is versatile for numerous research fields interest persistently growing. In present study, relationship between disease progression pathogen water level was investigated....
Eye flukes in fish are common freshwater lakes. Fish become infected by the penetration of cercariae released from snails, and high infection pressures may be associated with mortalities a Danish lake. Examination two other lakes, combined laboratory study, supported notion. We investigated 77 lakes level suggested occurrence cercarial pressure Dominant genera were Tylodelphys Diplostomum covering range species identified PCR sequencing 18S (partial)-ITS1-5.8S-ITS2-28S (partial) rDNA....
A parasitological investigation of Danish farmed freshwater (180 fish) and marine rainbow trout (170 fish), Oncorhynchus mykiss, was performed with an emphasis on the occurrence zoonotic parasites. Reliability methods applied assessed by examining fish from a stock wild Atlantic cod Gadus morhua caught in Sound (Øresund). While carried number parasites, we found that fish, both fresh environment, were free these Non-zoonotic parasites eye-flukes Diplostomum paracaudum, D. pseudospathaceum...
Marker-assisted selective breeding of fish with higher levels resistance towards specific pathogens may improve health, but the impact host genotype on susceptibility to multiple pathogen infections is still poorly investigated. This study examined in rainbow trout Oncorhynchus mykiss infection eye fluke Diplostomum pseudospathaceum. We used genetically selected trout, carrying SNPs associated parasitic ciliate Ichthyophthirius multifiliis, and exposed cercariae. showed that partly resistant...
When diseases in fish are discovered, the show either clinical signs or behavioural changes. At this timepoint morbid and decreased welfare economic loss may be a consequence for production facilities. Therefore, prophylaxis early detection of pathogens before disease occur could present facility managers with possibility to intervene treat outcome. For first time, environmental DNA/RNA (collectively eNA) has been used detect salmonid pathogen Aeromonas salmonicida subsp. water hosting...
A study was made to observe the effect of cobalt-60 irradiation on viability Paragonimus westermani metacercariae in Sinopotamon chekiangense crabs. The crabs were collected mountain regions Zhejiang Province China which paragonimiasis is endemic. Adult cats and albino mice infected with irradiated at different doses. Dissection host animals conducted 90 or 30 days, respectively, after infection for recovery lung flukes. Anti-metacercariae antibody measured by enzyme-linked immunosorbent...
