Analisi biomolecolare di ceppi di Canine Distemper Virus (CDV) in furetti domestici (Mustela putorius furo)
2011
L’agente eziologico del cimurro (CDV) appartiene alla famiglia Paramyxoviridae, genere Morbillivirus ed è causa di una patologia infettiva e contagiosa in canidi, mustelidi e procionidi. Gli Autori, descrivono un caso clinico di cimurro in due furetti domestici vaccinati con un ceppo Onderstepoort avianizzato. e la caratterizzazione biomolecolare del CDV isolato. I furetti presentavano un quadro clinico caratterizzato da dermatite pruriginosa e squamo-purulenta, alla regione del mento, peri-labiale, peri-vulvare ed al condotto uditivo esterno. I soggetti venivano a morte tre settimane dopo l’esordio dei sintomi. I campioni di croste prelevati sono stati sottoposti ad estrazione degli acidi …

Climate change and cyclic predator-prey population dynamics in the high Arctic.
2009
The high Arctic has the world's simplest terrestrial vertebrate predator–prey community, with the collared lemming being the single main prey of four predators, the snowy owl, the Arctic fox, the long-tailed skua, and the stoat. Using a 20-year-long time series of population densities for the five species and a dynamic model that has been previously parameterized for northeast Greenland, we analyzed the population and community level consequences of the ongoing and predicted climate change. Species' responses to climate change are complex, because in addition to the direct effects of climate change, which vary depending on species' life histories, species are also affected indirectly due to…
Secondhand horror: effects of direct and indirect predator cues on behavior and reproduction of the bank vole
2019
Risk recognition by prey is of paramount importance within the evolutionary arms race between predator and prey. Prey species are able to detect direct predator cues like odors and adjust their behavior appropriately. The question arises whether an indirect predation cue, such as the odor of scared individuals, can be detected by conspecifics and subsequently affects recipient behavior. Parents may also transfer their experience with predators to their offspring. In two experiments, we assessed how direct and indirect predation cues affect bank vole (Myodes glareolus) foraging behavior, reproduction, and pup fitness. Weasel (Mustela nivalis) odor served as the direct cue, whereas the odor o…
Comparative genomics and proteomics of Helicobacter mustelae, an ulcerogenic and carcinogenic gastric pathogen
2010
Abstract Background Helicobacter mustelae causes gastritis, ulcers and gastric cancer in ferrets and other mustelids. H. mustelae remains the only helicobacter other than H. pylori that causes gastric ulceration and cancer in its natural host. To improve understanding of H. mustelae pathogenesis, and the ulcerogenic and carcinogenic potential of helicobacters in general, we sequenced the H. mustelae genome, and identified 425 expressed proteins in the envelope and cytosolic proteome. Results The H. mustelae genome lacks orthologs of major H. pylori virulence factors including CagA, VacA, BabA, SabA and OipA. However, it encodes ten autotransporter surface proteins, seven of which were detec…

Update of the distribution and habitat use of the wildcat, pine marten and weasel in Sicily
2020
The wildcat (Felis silvestris), the pine marten (Martes martes) and the weasel (Mustela nivalis) are key members of the mammalian community in Sicily, actually performing the role of top predators and consequently influencing the trophic chain both in natural and agricultural areas. However, despite their protected status, very little information is available regarding their occurrence and ecology. Here, by verifying published studies, collecting personal observations and analyzing novel field data obtained by camera traps, we update their spatial distribution in Sicily, contributing to a better understanding of their habitat use and suggesting future research to improve our knowledge of th…
