Abstract:

Between 2015 and the beginning of 2018 (January-March), 30 cetaceans were found 
stranded along
the Ligurian Sea coast of Italy. Necropsies were performed in 22 cases and 
infectious diseases resulted
the most common cause of death. Three striped dolphins, showed a severe 
coinfection involving
the monophasic variant of Salmonella Typhimurium (Salmonella 1,4,[5],12:i:-). 
The isolates were
characterized based on antimicrobial resistance, Multiple-Locus Variable-number 
tandem-repeat
Analysis (MLVA) and whole-genome sequencing (WGS). All isolates demonstrated 
the same multidrug
resistant genotype (ASSuT isolates), showed three different MLVA profiles, two 
of which closely related,
and were identified as Sequence Type 34. Moreover, Single nucleotide 
polymorphisms (SNP) analysis
confirmed strong correlations between two out of the three isolates. To our 
knowledge, S. 1,4,[5],12:i:-,
one of the most common serovars in cases of human infection and food sources 
worldwide, has not
previously been described in marine mammals, and reports of 
Salmonella-associated disease in freeranging
cetaceans are rare. These results highlight the role of cetaceans as sentinel 
species for zoonotic
and terrestrial pathogens in the marine environment, suggest a potential risk 
for cetaceans and public
health along the North Western Italian coastline and indicate cetaceans as a 
novel potential reservoir for
one of the most widespread Salmonella serovars.

attention the publication of our last research published by the scientific 
journal Progress in Oceanography.

ABSTRACT

The impact of commercial fisheries on marine top predators is currently the 
focus of considerable international concern. In spite of the recognition of the 
competition between fisheries and marine predators for the same resources, few 
comprehensive assessments of the level of overlap between marine predators and 
fisheries have been conducted. Data from 273 daily boat surveys over a period 
of 4 years along the northwestern coast of Spain were used to assess the 
environmental, topographic, and anthropogenic correlates of habitat use and 
relative density of short-beaked common dolphins. Moreover, the degree of 
vulnerability of this marine top predator to coastal fisheries was assessed by 
identifying the type of fisheries associated with the presence of common 
dolphins. Our results reported that common dolphin presents a fine-scale 
pattern of habitat use, with an unequal use of available habitat and varying 
relative abundance, which was mostly related to the variation in environmental, 
topographic, and anthropogenic variables. The high occurrence of common 
dolphins in zones characterized by a high bottom trawl fishing pressure was 
indirectly linked to the susceptibility of these marine predators to fishing 
activities. These findings can be used as a relevant indicator of the degree of 
vulnerability of common dolphins to human pressure providing comprehensive 
information on which to base conservation and management strategies.
