Bacterial infections are a serious problem in aquaculture since they can result in massive mortalities in farmed fish and invertebrates. Vibriosis is one of the most common diseases in marine aquaculture hatcheries and its causative agents are bacteria of the genus Vibrio mostly entering larval rearing water through live feeds, such as Artemia and rotifers. The pathogenic Vibrio alginolyticus strain V1, isolated during a vibriosis outbreak in cultured seabream, Sparus aurata, was used as host to isolate and characterize the two novel bacteriophages φSt2 and φGrn1 for phage therapy application. In vitro cell lysis experiments were performed against the bacterial host V. alginolyticus strain V1 but also against 12 presumptive Vibrio strains originating from live prey Artemia salina cultures indicating the strong lytic efficacy of the 2 phages. In vivo administration of the phage cocktail, φSt2 and φGrn1, at MOI = 100 directly on live prey A. salina cultures, led to a 93% decrease of presumptive Vibrio population after 4 h of treatment. Current study suggests that administration of φSt2 and φGrn1 to live preys could selectively reduce Vibrio load in fish hatcheries. Innovative and environmental friendly solutions against bacterial diseases are more than necessary and phage therapy is one of them.

“…Previous reports of wound infections caused by V. alginolyticus have not reported isolations of this organism from blood [8–11]. In addition, V. alginolyticus has also been implicated in conjunctivitis [4,12,13], middle ear infection [14], chronic otitis media [15], peritonitis [16], intracranial infection [17], sphenoiditis [18], necrotizing fasciitis [5], bacteremia [3], chronic diarrhea, and gastroenteritis [2,19,20].…”

Cellulitis in immunocompetent hosts is usually caused by skin organisms and responds to oral antibiotics. In immunocompromised hosts, such as end-stage renal disease (ESRD) patients, unusual organisms with unpredictable pathogenicity can cause infections. We present two cases with isolates that are usually encountered in coastal waters. The first case describes a 71-year-old African-American ESRD patient who presented with bacteremia secondary to a wound infection after exposure to flood waters in a tropical storm. The second case describes a 70-year-old Caucasian male ESRD patient who developed septic shock after a trivial wound inflicted while on a shrimp boat. Both patients were successfully treated with appropriate antibiotics and supportive measures. The infective agents in both cases belong to the halophilic Vibrio species. The causative agent of cellulitis and bacteremia in the first hemodialysis patient was identified as Vibrio alginolyticus, a non-lactose-fermenting gram-negative bacillus that is rarely isolated from blood. The second patient presented with septic shock owing to Vibrio vulnificus, which is a lactose-fermenting bacillus known to produce severe localized or systemic illness. In both cases, the common features were ESRD-related immunocompromised state and exposure to marine environments. These two cases of life-threatening cellulitis and bacteremia are presented as examples of environmental pathogens common to a marine environment in coastal areas and the imperative need of rapid identification and prompt initiation of treatment in immunocompromised hosts.

“…Among Vibrio species, only some are indeed pathogenic. With the advantage of having accessed the plastisphere through shotgun sequencing, we observed potential animal and human pathogens as the most abundant taxa, for example, V. alginolyticus, commonly found in marine environments and medically important for causing ear, eye, and wound infections in humans [91][92][93]. This species is also present in the bodies of aquatic animals such as pufferfish, where it is responsible for producing toxins like tetrodotoxin (TTX) [94].…”

Plastics in the ocean create the “plastisphere”, a diverse habitat hosting various life forms. Other than the pollution induced by plastics, the co-occurrence of primary producers, symbiotic organisms, decomposers, and pathogens within the plastisphere raises questions about how they influence the dynamics of marine ecosystems. Here, we used a shotgun DNA-sequencing approach to describe the species thriving on floating plastics collected in two Mediterranean sites. Our findings revealed many species of bacteria, eukaryotes, viruses, and archaea on each plastic. Proteobacteria was dominant (70% of reads in the entire dataset), with other groups such as Ascomycota fungi (11%) and Bacteroidetes (9%) also being represented. The community structure was not affected by the polymeric composition or the plastic shape. Notably, pathogenic Vibrio species, including V. campbelli, V. alginolyticus, and V. coralliilyticus, were among the most abundant species. Viruses, despite showing lower relative abundances, occurred in all samples, especially Herpesvirales, Caudovirales, and Poxviridae groups. A significant finding was the presence of the White Spot Syndrome virus (WSSV). This pathogen, responsible for devastating outbreaks in aquaculture systems, had not been previously reported in the marine plastisphere. Our study emphasizes the need for further investigation into the ecological and economic impacts of plastisphere organisms in the ocean.
