“…In Europe, a survey reported that several dozen cases were reported each year in Finland and Sweden in the 1990s [13], but globally, the incidence of human diphyllobothriosis has decreased over the last 20 years in northern and eastern Europe [8]. Dibothriocephalus latus, the endemic species in Europe, parasitizes freshwater fish (mainly pikes and perches), and has been detected in as much as 25% of perches in Como Lake (Italy) in a recent study [14]. D. latus infection tends to be considered a re-emerging disease in Switzerland due to the consumption of raw or marinated fish prepared as tartare, carpaccio or gravlax, but there are no signs that it is similar in France or Italy.…”

“…The main species that cause diphyllobothriosis is D. latum. This tapeworm is native to Scandinavia, western Russia, and the Baltics, though it is now also present in North America, especially the Pacific Northwest (Scholz, Garcia, Kuchta & Wicht, 2009) but it also presents in some subalpine lakes in the North of Italy (Gustinelli et al, 2016). Nowadays, Europe imposes strictly controls on aquaculture activities that breed fish for stoking purpose only for certain viral diseases (Council Directive 2006/88/EC) but not for bacterial or parasitic ones (Pastorino et al, 2017).…”

The introduction of fish for stoking purpose is a common operation to manage fisheries. This may cause ecological and sanitary risks to native aquatic biodiversity especially in fishless Alpine lakes. In these ecosystems, fish have been introduced by anglers for ages. Europe imposes strictly controls on aquaculture facilities that breed fish for stoking purpose only for viral disease but not for bacterial or parasitic ones. Moreover, the role of alien fish as carriers of pathogens is poorly studied. For these reasons, we performed two fish sampling campaigns in two Italian Alpine lakes (Dimon Lake and Balma Lake) to have qualitative information about alien fish populations and to perform a bacteriological survey on captured fish. In Dimon Lake we captured individuals of Cottus gobio and of Phoxinus phoxinus, while only individuals of Salvelinus fontinalis were sampled in Balma Lake. We isolated Aeromonas sobria and Plesiomonas shigelloides in Dimon Lake, which are bacteria widespread in aquatic environment. In Balma Lake, one fish was positive for Yersinia ruckeri, a primary pathogen present in aquaculture facilities that reared salmonids. Our study show how alien species may introduce bacteria that could be more virulent for native aquatic fauna or even pathogenic bacteria.

“…The host specificity of Dibothriocephalus species is quite broad, while humans may be the main definitive host, especially for D. latus [ 3 ]. In Europe, the European perch ( Perca fluviatilis ) is the most common host for D. latus , the Northern pike ( Esox lucius ) acts as a paratenic host, and the burbot ( Lota lota ) plays a minor role in human diphyllobothriasis [ 4 ]. P. fluviatilis has a wide distribution throughout the Northern Hemisphere and it is a suitable host for several endohelminth and zoonotic parasites [ 4 , 5 , 6 , 7 , 8 ].…”

“…D. latus is endemic in the subalpine lakes of Italy, Switzerland, and France [ 16 ]. At the beginning of the past century, diphyllobothriasis was widespread in its endemic area, but it apparently disappeared since the early 1980s [ 4 ]. Starting in 2000, it has re-emerged, particularly in the shores of the large subalpine lakes [ 4 , 16 , 17 , 18 , 19 ].…”

Dibothriocephalus latus (Linnaeus, 1758) (Cestoda: Diphyllobothriidea; syn. Diphyllobothrium latum), is a fish-borne zoonotic parasite responsible for diphyllobothriasis in humans. Although D. latus has long been studied, many aspects of its epidemiology and distribution remain unknown. The aim of this study was to investigate the prevalence, mean intensity of infestation, and mean abundance of plerocercoid larvae of D. latus in European perch (Perca fluviatilis) and its spatial distribution in three commercial fishing areas in Lake Iseo (Northern Italy). A total of 598 specimens of P. fluviatilis were caught in 2019. The total prevalence of D. latus was 6.5%. However, there were significant differences between areas (10.2% North; 7.3% Center; 1.5% South) (Chi-square test, p = 0.0018). The mean intensity of infestation ranged from 1 larva in southern area to 1.2 larvae in both the central and northern (Pisogne) areas. In addition, the mean abundance ranged from 0.02 in the southern area to 0.26 in the northern area (Pisogne). The total number of larvae (anterior dorsal—AD = 21; anterior ventral—AV = 1; posterior dorsal—PD = 15; posterior ventral—PV = 5) differed significantly between the four anatomical quadrants (Kruskal–Wallis test; p = 0.0001). The prevalence of D. latus plerocercoid larvae in European perch from Lake Iseo has long been investigated, but without an appropriate sampling design. With the present study, a broader analysis in spatial distribution has been added to the existing literature, revealing new information about D. latus distribution and occurrence in Lake Iseo, with new data that will be useful for health authorities and future studies.
