Biofilms are associated with persistence of Staphylococcus aureus infections and therapeutic failures. Our aim was to set up a pharmacodynamic model comparing antibiotic activities against biofilms examining in parallel their effects on viability biofilm mass. S. ATCC 25923 (methicillin-sensitive [MSSA]) or 33591 (methicillin-resistant [MRSA]) were obtained by culture 96-well plates for 6 h/24 h. Antibiotic assessed after 24/48 h exposure concentrations ranging from 0.5 512 times the MIC....
ABSTRACT Piscine orthoreovirus‐1 and 3 (PRV‐1, PRV‐3) cause highly prevalent infection in cultured salmonids can induce heart skeletal muscle inflammation (HSMI) resulting economic losses aquaculture. However, to date, PRV‐1 PRV‐3 have withstood replication continuous cell lines. In this study, we used beating cultures obtained from different developmental stages of rainbow trout ( Oncorhynchus mykiss ) (RTC‐L RTC‐A) tested their ability sustain PRV‐3. Furthermore, compared the pattern...
Vaccination is the best form of protecting fish against viral diseases when pathogen cannot be contained by biosecurity measures. Vaccines based on live attenuated viruses seem to most effective for vaccination challenging pathogens like Cyprinid herpesvirus 3 . However, there are still knowledge gaps how these vaccines effectively protect from deadly disease caused epitheliotropic CyHV-3, and which aspects non-direct protection skin or gill integrity function important in aquatic...
Carp edema virus (CEV) is the causative agent of koi sleepy disease (KSD), a serious gill affecting common carp, Cyprinus carpio, and its ornamental variety, koi. After recent detections in various countries around world, KSD has emerged as new global carp. However, prevalence infection carp populations given geographical region not been studied thoroughly. The present communication reports an investigation into presence CEV Germany. For this purpose, samples collected from suffering...
Abstract Shewanella spp. are Gram‐negative, rod‐shaped, motile bacteria that widely distributed in marine and freshwater environments. The present the physiological microflora of fish from temperate waters known as spoilage species. From clinically healthy with skin ulcerations, is regularly isolated, indicating a possible role pathogen. In this study, 74 isolates were analysed. For species identification, biochemical techniques, 16S rRNA sequencing, MALDI ‐ TOF MS Sherlock Microbial...

Abstract Aeromonas spp. are ubiquitous in the aquatic environment, acting as facultative or obligate pathogens for fish. Identifying is important pathogenesis and prognosis diagnostic cases but can be difficult because of their close relationship. Forty‐four already characterized isolates were analysed by 16S rRNA gene sequencing, gyrase B analysing fatty acid profiles, biochemical reactions MALDI ‐ TOF MS . To determine pathogenicity, cytotoxicity, adhesion to mucus expression 12 virulence...
Abstract Due to their pathogenic potential, identifying Vibrio species from recirculating aquaculture systems ( RAS ) for Pacific white shrimp Litopenaeus vannamei is of great importance determine the risk animal's as well consumer's health. The present study compared identification results a total 93 isolates, including type strains and isolates aquaculture. Results biochemical identifications, 16S rRNA sequencing, sequencing uridylate kinase encoding gene pyrH analysis protein spectra...
Abstract Tropical shrimp, like Litopenaeus vannamei , in land‐based recirculating aquaculture systems (RAS) are often kept at low water salinities to reduce costs for artificial sea salt and the amount of salty wastewater. Although these shrimp tolerant against salinities, innate immunity suppression changes microbial composition can occur. As especially Vibrio spp. relevant health, alterations species community were analysed from six RAS, run 15‰ or 30‰. Additionally, pathogenicity factors...
Abstract Environmental stressors such as micro‐ and nanosized plastic particles (MNPs) or crude oil have a detrimental effect on aquatic animals; however, the impact upon cardiovascular system of fish remains relatively under‐researched. This study presents novel approach for investigating MNPs cardiac fish. We used salmonid larvae cell cultures derived from hearts exposed them to environmental stressors. Following exposure oil, exhibited some variation in contraction rate. In contrast,...
This study outlines a multifactorial disease outbreak in population of the freshwater shrimp Neocaridina davidi, with focus on rarely described parasitic alga. Within this outbreak, low but consistent mortality was observed. During microscopic examination, an infection bacterial and fungal-like agents diagnosed. Furthermore, green alga Cladogonium sp. found pleopodal regions. The compromised body surface shrimp, its rhizoids penetrated chitin shell reached into subcutaneous tissue. might be...
Replacing fishmeal, a finite resource with high market demand, in the diet of carnivorous rainbow trout proteins from alternative sources may be challenge for these fish. Therefore, this study investigated whether replacing fishmeal protein derived Hermetia illucens or Arthrospira platensis could promote disease susceptibility local populations different growth performance. This was assessed vitro by measuring to infection viral haemorrhagic septicaemia virus (VHSV) bacterium Yersinia...
Genetic adaptation to new environmental conditions, such as changing diets, has always played a key role in the evolution of animals. Fish, particular, have great genetic potential for adaptability regional demands. Feeding diets devoid marine resources carnivorous fish species is paramount enable fully sustainable aquaculture and independence capture fisheries. Therefore, novel sources protein substituting fishmeal feed are increasing interest aquaculture. However, use plant-based diet...
