An unusual mortality event involving cetaceans, mainly striped dolphins Stenella coeruleoalba (Meyen, 1833), occurred along the Tyrrhenian Sea coast of Italy during the first 3 mo of 2013. Based on post-mortem analyses carried out according to body condition on 66 dolphins (54% of stranded animals), several hypotheses to explain the causes of this mortality event were proposed. Although no definitive conclusions can be drawn, dolphin morbillivirus was deemed the most likely cause, although other infectious agents (including Photobacterium damselae damselae and herpesvirus) or environmental factors may also have contributed to this recent mortality event.

Meningoencephalitis and Listeria monocytogenes, Toxoplasma gondii and Brucella spp. coinfection in a dolphin in Italy

Listeria monocytogenes, Toxoplasma gondii and Brucella spp. can infect a wide range of species, including humans. In cetaceans, meningoencephalitis has been associated with T. gondii and Brucella spp. infection, whereas to our knowledge, L. monocytogenes infection has not previously been reported. Meningoencephalitis and L. monocytogenes, T. gondii and Brucella spp. were identified by means of both direct and indirect laboratory techniques in an adult female striped dolphin Stenella coeruleoalba found stranded in January 2015 on the Ligurian Sea coast, northwestern Italy. The animal was emaciated, and histopathology disclosed severe meningoencephalitis. The nature of the inflammatory response and intra-lesional protozoa were consistent with a mixed infection by L. monocytogenes, T. gondii and Brucella spp. We believe this is an unprecedented case of infection by 3 zoonotic pathogens and also the first bacteriologically confirmed case report of neurolisteriosis in cetaceans. Cerebral toxoplasmosis and neurobrucellosis may have led to the animal's disorientation and stranding, with L. monocytogenes having likely exacerbated the coinfection leading to the demise of this dolphin.

“…The present study is the first comprehensive review to examine factors that influence the success of collecting biopsy samples from free-ranging cetaceans as well as evaluate factors that influence physiological and behavioral responses for a wide range of cetacean species that have been sampled via biopsy techniques.

Review of cetacean biopsy techniques: Factors contributing to successful sample collection and physiological and behavioral impacts

Biopsy techniques have been developed to collect skin and blubber samples through non-lethal methods. One sample can provide data on genetics, prey preferences, foraging ecology, contaminant loads, and physiological processes. The limited data available suggest that biopsy wounds heal quickly and that there are usually no discernable adverse health effects. Published accounts on factors contributing to the success of collecting biopsy samples and the behavioral impacts to cetaceans following biopsy sampling were standardized to permit statistical analysis. Several factors contribute to the success of acquiring samples; however, sampling rates do not differ significantly between delivery devices. Behavioral responses to biopsy sampling vary by species and other factors. The most predominant response for odontocetes is low, while low and moderate responses are equally prevalent for mysticetes. The use of retrieval lines may increase the occurrence of moderate and strong responses by mysticetes. These findings suggest that biopsy sampling is relatively benign, causing only minor and short-lived responses. However, most researchers do not report sufficient data to assess short-and long-term physiological and behavioral impacts. Finally, limited data suggest that biopsy sampling does not impact cetacean habitat use or distribution patterns. Yet these impacts are rarely investigated, so additional data are needed.
