Abstract Tilapia culture is an important source of income and nutrition to many rural families. Since 2000, the production tilapia increased reached domestic global markets. Major farmed species Nile ( Oreochromis niloticus ), in earthen ponds cage cultures. Intensification contributed disease outbreaks, with bacterial infections causing mortalities morbidities, threatening sustainable production. At farms, high nutrient concentrations, water temperature fish densities enhance growth...
As aquaculture production and the consumption of products increase, possibility contracting zoonotic infections from either handling or ingesting these also increases. The principal pathogens acquired topically fish shellfish through spine/pincer puncture open wounds are Aeromonas hydrophila, Edwardsiella tarda, Mycobacterium marinum, Streptococcus iniae, Vibrio vulnificus V. damsela. These pathogens, which all indigenous to aquatic environment, have been associated with disease outbreaks in...
Abstract Black soldier fly [BSF; Hermetia illucens L. (Diptera: Stratiomyidae)] larvae are very effective in transforming low‐grade food waste into valuable high‐end proteins and fat, intensive production facilities. The output of this species is growing quickly, but upscaling brings risks to the health status reared insects. Until now, not a single major case disease outbreak caused by pathogen BSF unit has been reported. This contrasts with data on other mass‐produced insects, which have...
Eel herpesvirus or anguillid 1 (AngHV1) frequently causes disease in freshwater eels. The complete genome sequence of AngHV1 and its taxonomic position within the family Alloherpesviridae were determined. Shotgun sequencing revealed a 249 kbp including an 11 terminal direct repeat that contains 7 136 predicted protein-coding open reading frames. Twelve these genes are conserved among other members another 28 have clear homologues cyprinid 3. Phylogenetic analyses based on amino acid...
Three regions of koi herpesvirus (KHV) genomic DNA were compared for 34 samples from Japan, six Indonesia, two Taiwan, one the Philippines, 13 Netherlands, UK, USA and Israel. The analyzed included known PCR-detection targets (SphI-5, 9/5 thymidine kinase gene). KHVs Asian countries very homogeneous, although variants noted based on a single nucleotide polymorphism. In contrast, seven found in outside Asia, closely related to another, they clearly distinct those Asian. results suggest that...
Aeromonas salmonicida is the causative agent of furunculosis, a disease that affects both salmonid and non-salmonid fish. Detection A. can be labour intensive time consuming because difficulties in distinguishing bacterium from other species given wide variety existing biochemical profiles slow growth characteristics which allow organisms to overgrow salmonicida. Herein, we report development specific immunoassay using gold-conjugated polyclonal antibodies for rapid detection fish tissues....
A recently described typing system based on sequence variation in the virulence array protein (vapA) gene, encoding A-layer surface array, allows unambiguous subtyping of Aeromonas salmonicida. In present study, we compile results from a total 675 A. salmonicida isolates, recovered over 59-year period 50 different fish species 26 countries. Nine novel types (15-23) are identified, several which display strong predilection towards certain hosts, including e.g. Cyprinidae and Pleuronectidae...
To support the role of insects as sustainable feed and food ingredients, evaluating their potential microbiological risk safety is crucial. In this study, we investigated presence antimicrobial resistance (AMR) genes in selected live opportunistic pathogenic bacteria isolated during rearing process from clinically healthy farm-reared crickets. Molecular analysis was performed by wholegenome sequencing a total 14 these bacterial strains, 7 house crickets (Acheta domesticus) banded (Gryllodes...
Cyvirus cyprinidallo2 (CyHV-2) is the causative agent of herpesviral hematopoietic necrosis in several economically important farmed freshwater fish species genus Carassius. Despite CyHV-2 strains being isolated and fully sequenced, there a lack detailed characterization consistent information on that exhibit high virulence adult goldfish through viral challenge by immersion, particularly context European host populations. Strains can cause highly virulent disease via this inoculation route...
ABSTRACT Carbapenems are considered last-resort antibiotics in health care. Increasing reports of carbapenemase-producing bacteria food-producing animals and the environment indicate importance this phenomenon public health. Surveillance for carbapenemase genes Dutch animals, environmental freshwater, imported ornamental fish revealed several chromosome-based bla OXA-48 -like variants Shewanella spp., including two new alleles, OXA-514 OXA-515 . Carbapenemase were not associated with mobile...
Dover sole (Solea solea) is an obligate ectotherm with a natural thermal habitat ranging from approximately 5 to 27°C. Thermal optima for growth lie in the range of 20 25°C. More precise information on needed cost-effective aquaculture. The main objective this study was determine optimal temperature juvenile and addition test hypothesis that final preferendum equals temperature. Temperature preference measured circular chamber acclimated 18, 22 28°C. Optimal by rearing at 19, 22, 25...
In a recirculation aquaculture system the drumfilter effluent can be used as substrate for heterotrophic bacterial production, which recycled feed. Because bacteria might contain pathogens, could reduce its suitability feed, it is important to characterize these communities. Bacteria were produced in growth reactors under different conditions: 7 h hydraulic retention time (HRT) vs. 2 h, sodium acetate molasses, and ammonia nitrate. The community of was from those found reactors. However, all...
