“…The prevention of diseases caused by non-poliovirus enteroviruses such as Coxsackievirus B and Echovirus requires the identification of viral contamination sources and the development of effective intervention strategies and decontamination procedures for shellfish and aquatic ecosystem (Morley, 2010;Esposito et al, 2022).…”

Non-poliovirus enteroviruses (NPEV) are infectious agents which can determine various illness in human such as hand-foot-mouth syndrome, angina, respiratory diseases, acute or chronic heart disease, diarrhea, pancreatitis, acute hemorrhagic and conjunctivitis. These viruses are eliminated in the stool and thus contaminate the marine environment and shellfish. In Morocco, shellfish sanitary quality analysis does not include enteroviruses detection. Therefore, the objective of this study was to detect and to type enteroviruses in 288 mussel samples. These samples (Mytilus galloprovincialis) were collected between February 2014 and February 2015 from three wild populations (Bouregreg estuary, Yacoub Al Mansour, and Harhoura coast). 216 of 288 samples (75%) were revealed positive by the cell culture method, with 204 strains of NPEV (70.8%) and 12 strains of Poliovirus Type 1 (4.2%). The serotype of 204 NPEV strains has been determined a typable strains (64.7%) and non-typable strains (35.3%) in the marine environment. However, the proportion of untypable strains confirms the presence of new serotypes. The diseases caused by NPEV constitute an important public health problem. To fight against this human risk related to viral contamination, it is necessary to have a methodology for the control and virological monitoring of the marine ecosystem.

“…Applying a heating effect in the combined exposure caused the responses to be disrupted, indicating the limited tolerance of bivalve mollusks toward xenobiotics (Esposito et al 2022). The main sign was the absence of CtD and caspase-3 activation, increased e ux of CtD from lysosomes and highest lysosome destabilisation, attesting that the processes were suicidal for cells (Kågedal et al 2001;Pi et al 2017;Turk and Turk 2009).…”

Multistress effects lead to unpredicted consequences in aquatic ecotoxicology and are extremely concerning. The goal of this study was to trace how specific effects of the antibiotic salynomycin (Sal) and microplastics (MP) on the bivalve molluscs are manifested in the combined environmentally relevant exposures. Unio tumidus specimens were treated with Sal (0.6 µg L− 1), MPs (1 mg L− 1, 2 µm size), and both at 18°C (Mix) and 25°C (MixT) for 14 days. The redox stress and apoptotic enzyme responses and the balance of Zn/Cu in the digestive gland were analyzed. The shared signs of stress included a decrease in NAD+/NADH and Zn/Cu ratios and lysosomal integrity, and an increase in Zn-metallothioneins and cholinesterase levels. MP caused a decrease in the glutathione (GSH) concentration and redox state, total antioxidant capacity, and Zn levels. MP and Mix induced coordinated apoptotic/autophagy activities, increasing caspase-3 and cathepsin D (CtD) total and extralysosomal levels. Sal activated caspase-3 only and increased by five times Cu level in tissue. Due to the discriminant analysis, the cumulative effect was evident in the combined exposure at 18°C. However, under heating, the levels of NAD+, NADH, GSH, GSH/GSSG and metallothionein-related thiols were decreased, and coordination of the cytosolic and lysosomal death stimuli was distorted, confirming that heating and pollution could exert unexpected synergistic effects on aquatic life.

“…Since vulnerabilities of aquaculture to CC-OA are currently poorly understood, research based on the prevention and sustainability of shellfish farming under these conditions is more than necessary given that climate change also causes indirect consequences for the marine environment in the form of changing patterns of salinity, frequency of extreme weather conditions and algal blooms, spread of invasive species and diseases (Alleway et al, 2019). Marine species have dealt with CC-OA throughout their evolutionary history, however, the fast climate changes that are occurring may affect the capacity of organisms to adapt to these variations, affecting their survival, physiology and growth (Stavrakidis-Zachou et al, 2021;Esposito et al, 2022). Temperature and pH are two of the most important physical factors affecting intertidal organisms such as shellfish (Kovačić et al, 2023).…”

This study examined the effects of dietary supplementation of queen scallop Aequipecten opercularis with an indigenous strain of lactic acid bacteria (LAB), Lactiplantibacillus plantarum I, previously isolated from its digestive tract, on gut microbial populations and growth rates during cultivation under simulated climate change conditions (pH 7.8, T = 16 ± 2 °C). After one month of feeding, the results showed a noticeable reduction in aquaculture diseases causing pathogens while maintaining sufficient viable Lpb. plantarum I cells. A higher pH and temperature resulted in higher growth rates, measured by the weight and length of scallops, compared to the control group. The results obtained shed light on the influence of the addition of lactic acid bacteria on the growth of bivalve mollusks under normal and climate change conditions, and provide control of pathogenic microorganisms. In the context of climate change, host-pathogen interactions need to be recognized and put under control by applying natural solutions to minimize the environmental footprint.
