The fan mussel, Pinna nobilis, represents the largest bivalve endemic to Mediterranean Sea. Since 2016, dramatic mass mortality of this species has been observed in several areas. first surveys suggested that Haplosporidium pinnae (currently considered species-specific) was main etiological agent, but recent studies have indicated a multifactorial disease may be responsible for phenomenon. In study, we performed molecular diagnostic analyses on P. rudis, and heterologous host from island...
The genus Eustrongylides includes nematodes that infect fish species and fish-eating birds inhabiting freshwater ecosystems. Nematodes belonging to the are potentially pathogenic for humans; infection occurs after consumption of raw or undercooked fish. In two-year period 2019-2020, a total 292 eight were examined occurrence spp. from Lake San Michele, small subalpine lake in northwest Italy. prevalence infestation was 18.3% Lepomis gibbosus, 16.7% Micropterus salmoides, 10% Perca...
Clinostomum complanatum, a digenean trematode of the Clinostomidae family, is fish-borne zoonotic parasite responsible for Halzoun syndrome in humans and transmitted through consumption raw or undercooked freshwater fish. Of total 112 specimens European perch (Perca fluviatilis) sampled from subalpine lake (Lake Endine) North Italy 2019, 21 (18.75%) tested positive encysted metacercariae fillet. This study reports first isolation C. complanatum P. fluviatilis highlights possible risk...
Sturgeon farming is rapidly expanding in Europe, where Italy ranks first farmed caviar production. A major threat to sturgeon health captivity infection with Acipenser European Iridovirus (AcIV-E), a viral disease definitively identified 2016. Here we present data on the occurrence of AcIV-E 482 sturgeons (age ≤ 12 months, species genus and Huso huso) collected from farms northern between January 2021 December 2023. The status each specimen was determined by necroscopy virological assay....
Lactococcosis is a fish disease of major concern in Mediterranean countries caused by Lactococcus garvieae. The most susceptible species the rainbow trout (Oncorhynchus mykiss), suffering acute associated with elevated mortalities compared to other species. References reported that salmonids are also disease, but no mortality outbreak has been described date. aim this study was present occurred brook (Salvelinus fontinalis) farmed northwestern Italy during summer 2018. Fish exhibited...
Mycobacterium pseudoshottsii, a slow-growing mycobacterium closely related to M. marinum, has been isolated only in wild fish the United States and Japanese farms date. Here, we report cases of mortality three farmed species (Dicentrarchus labrax, Sparus aurata, Sciaenops ocellatus) caused by pseudoshottsii Italy. Samples underwent necropsy, histology, culture with pathogen identification based on PCR sequencing housekeeping genes (16S rRNA, hsp65, rpoB). Multifocal coalescing granulomatous...
The Mycobacterium fortuitum group (MFG) consists of about 15 species fast-growing nontuberculous mycobacteria (NTM). These globally distributed microorganisms can cause diseases in humans and animals, especially fish. increase the number belonging to MFG diagnostic techniques panel do not allow clarify their real clinical significance. In this study, biomolecular were adopted for determination 130 isolates derived from fish initially identified through biochemical tests as NTM MFG....
Reptile-associated salmonellosis (RAS), Salmonella infection in humans, is acquired through contact with reptiles. Reptiles have become popular pet animals, and RAS likely to be an underestimated but growing problem. No epidemiological data about are routinely collected Italy. In order estimate the occurrence of Italian human population investigate exposure, two studies on patients sporadic were carried out Piedmont region, along evaluation exposure public places displaying reptiles a survey...
Abstract Carnobacteria are common bacteria in cold and temperate environments; they also reported during fish mortality events. In a previous study, carnobacteria were isolated from the eyes of healthy wild salmonids high-mountain lake. To better understand these findings, captured three lakes (Lower Upper Balma Lake, Rouen Lake; northwest Italy) August 2019 subjected to bacteriological histological examination. Although all healthy, 8.7% Lake), 24% (Upper 32.6% (Rouen Lake) positive for...
We report the first case of Acipenser iridovirus European (AcIV-E) infection in starry sturgeon (Acipenserstellatus) and sterlet (A.ruthenus) reared Northern Italy. During 2018, mortality began A.stellatus A.ruthenus specimens co-habitation with Russian positive for AcIV-E. Molecular analyses were done on gills to amplify a fragment major capsid protein (MCP) gene using real-time PCR against DNA samples was further sequenced phylogenetic performed. The MCP sequences highly similar virus...
This study aimed to assess the biological and sanitary conditions of alien fish in a high-mountain lake (Balma Lake) located Cottian Alps. A single sampling session (August 2018) using gillnets collected 90 specimens brook trout (Salvelinus fontinalis). Sex age were determined (59 females 31 males, class 0+ 4+). Regression analysis showed no difference total weight length between males (ANCOVA: F = 0.453; p 0.954). The mean condition factor (Kmean) decreased with increasing for females....
The genus Vibrio currently contains 147 recognized species widely distributed, including pathogens for aquatic organisms. infections in elasmobranchs are poorly reported, often with identifications as sp. and without detailed diagnostic insights. purpose of this paper is the description isolation identification process spp. following a mortality event Scyliorhinus canicula juvenile reared an Italian public aquarium. Following investigations aimed at excluding presence different marine fish...
Oysters are sessile, filter-feeding bivalve molluscs widely distributed in estuarine and coastal habitats worldwide. They constitute a valuable resource for fisheries extensive aquaculture provide essential ecological services. Yet, their genetic diversity distribution remain understudied. The variability shell morphology complicates species classification, which is influenced by environmental factors. Although molecular phylogenetics research has refined oyster taxonomy identified...
The aim of this study was to describe liver alterations observed in a bullhead (Cottus gobio) population from high-mountain lake (Dimon Lake; 1857 m a.s.l.) located Carnic Alps (Northeast Italy). Two fish sampling campaigns (summer and autumn) were performed 2017 explore the possible causes phenomenon. In addition, investigate typical features C. gobio, control specimens captured Degano Creek same seasons. Total length, weight, weight recorded both sites. Fulton’s condition factor (K)...
The gut microbiota has become a topic of increasing importance in various fields, including aquaculture. Several fish species have been the subject investigations concerning intestinal microbiota, which compared different variables, portions, environment, and diet. In this study, farmed wild brook trout (Salvelinus fontinalis) were analyzed, wall content medial portion intestine considered separately. A total 66 (age class 2+) sampled, 46 20 trout, two years. Microbiota data obtained using...
Fish mycobacteriosis is a widespread global problem caused by species of non-tuberculous mycobacteria (NTM). Mycobacterium marinum one the most often involved in disease episodes aquarium and farmed fish. Since there currently no available effective therapy or vaccine, prompt search for routes entry key to limiting damage induced disease. Here we report case follow up European sea bass (Dicentrarchus labrax) farm located Northern Italy, which environmental samples newly added fish batches...
The nematode Eustrongylides excisus is a parasite of freshwater fish- and fish-eating birds, with known differences on prevalence values among fish species. Thus, the present study aims to explore hypothesis that feeding behavior size belonging different trophic levels could explain such differences. For that, 14 sampling sites were selected perform parasitological survey Lake Garda (Italy) during spring-summer 2020. Amplification nuclear ribosomal internal transcribed spacer (ITS) rDNA...
Dibothriocephalus latus (Linnaeus, 1758) (Cestoda: Diphyllobothriidea; syn. Diphyllobothrium latum), is a fish-borne zoonotic parasite responsible for diphyllobothriasis in humans. Although D. has long been studied, many aspects of its epidemiology and distribution remain unknown. The aim this study was to investigate the prevalence, mean intensity infestation, abundance plerocercoid larvae European perch (Perca fluviatilis) spatial three commercial fishing areas Lake Iseo (Northern Italy)....
