Unusual localization of Dirofilaria repens (Spirurida: Onchocercidae) infection in the testicle of a dog     

《Comparative immunology, microbiology and infectious diseases》2019

This report describes an uncommon localization of Dirofilaria repens in the testicle of a nine-year-old dog from southern Italy. The dog underwent neutring and three adult nematodes were found in the tunica vaginalis. At gross anatomy, no pathological changes were observed on the tunica, in the testicle or epididymis. The parasites, one female and two males, were morphologically and molecularly identified as D. repens. This is the first report of D. repens in the canine testicle in Italy. This case report highlights the asymptomatic nature of D. repens infection, suggesting that dogs living in endemic areas may act as silent carriers. Careful screening and an effective chemoprophylaxis should be ensured for all animals potentially exposed to D. repens infection in order to reduce the risk of infection to humans in areas where the parasite is endemic.  相似文献

Leaf necrosis and twig dieback of sweet persimmon (Dyospiros kaki L.) caused by Pseudomonas syringae pv. syringae in Italy     

M. Scortichini  D. D'Ascenzo  Daniela Di Silvestro 《European journal of plant pathology / European Foundation for Plant Pathology》1998,104(6):625-627

In spring 1996, extensive leaf necrosis and twig dieback were observed on young sweet persimmon (Dyospiros kaki L.) trees, cultivars O'Gosho, Hachija, Mercatelli and Kaki-tipo planted in the Abruzzo region (central Italy). Many trees were killed. When the dieback reached the trunk, in many cases, new vegetation was noticed above the graft point. The cultivar Jiro-C was not affected by the disease. During 1997, no symptoms were observed on any plant. The orchard was planted in a clay soil with a very low content of organic matter. Biochemical, nutritional and pathogenicity tests indicated Pseudomonas syringae pv. syringae van Hall as the causal agent of the disease. This is the first report of this bacterium as a pathogen of sweet persimmon in Europe.  相似文献   

Effect of owner experience,living environment,and dog characteristics on owner reports of behavior of Argentine Dogos in Italy     

《Journal of Veterinary Behavior: Clinical Applications and Research》2014,9(4):151-157

Previous research reported contrasting results on the effect of owner experience on dog behaviors. This may be because of dog breed genetic variability, differences in expectations, management choices, and attitude toward their dogs by owners of dogs of different breeds. A study of a single breed may help provide a better insight into this issue. A convenience sample of 94 participants, owners of 181 Argentine Dogos, was recruited to provide information on their dogs' behaviors through a questionnaire. Participants were classified according to their previous general experience or inexperience with dogs and whether they had previously owned an Argentine Dogo (expert vs. naive owners). Reasons for getting a dog (companionship, guarding, hunting, breeding) and attendance at dog-training classes were also explored. Pearson chi-square tests and binary logistic regressions were used to analyze the data. Previous inexperience with dogs was associated with a higher prevalence of dogs that were fearful of children and unknown dogs. Naive Dogo owners perceived that their dogs were more obedient and friendly toward strangers but aggressive toward children, than those belonging to Argentine Dogo experts. It also appeared that living environment and the dog's age are critical predictors of many outcome variables. Kennel living was found to be predictive of car and food protection, owner-directed aggression and aggression toward children, whereas house living was associated with fear of loud noises. Changes related to the dogs' age were probably related to behavioral development in the dogs. Destructiveness, excessive body licking, and protective aggression were more common in younger dogs, whereas aggression to unknown dogs was more common in older ones. Protective aggression was more common in males, and fear of startling noises was more common in females. Intact dogs showed a higher probability of having attention-getting behavior, and neutered dogs were more fearful of traffic. Our findings are correlative. Even if causative links cannot be made, our findings certainly provide direction for further investigation.  相似文献   

Multi‐temporal Digital Photogrammetric Analysis for Quantitative Assessment of Soil Erosion Rates in the Landola Catchment of the Upper Orcia Valley (Tuscany,Italy)     

Pietro P. C. Aucelli  Massimo Conforti  Marta Della Seta  Maurizio Del Monte  Lorenzo D'uva  Carmen M. Rosskopf  Francesca Vergari 《Land Degradation \u0026amp; Development》2016,27(4):1075-1092

This paper focuses on the analysis of the slope and catchment erosion dynamics in a typical Mediterranean context and its sensitivity to recent climatic and socio‐economic changes. The main objective of the present study is to test the reliability of digital photogrammetric analysis to evaluate the time and space evolution of erosion processes mainly triggered by surface running waters and landslides for about the last 60 years. The selected test area is the Landola catchment, a minor tributary of the Upper Orcia River Valley (Southern Tuscany). The Upper Orcia valley is a key site for the comprehension of denudation processes typically acting in Mediterranean badland areas thanks to the following: (i) the availability of long‐lasting erosion monitoring datasets (20 years' long direct measurements at erosion ‘hot spots’); (ii) its representativeness as a sub‐humid Mediterranean badland area; and (iii) the rapidity of development of erosion processes, which makes it suitable as an open‐air laboratory for the study of badland dynamics. The outputs of this work highlight that the application of high‐resolution digital photogrammetric methodologies can represent a powerful and low‐cost tool to evaluate rates and spatial–temporal distribution of denudation processes, as confirmed by the validation through field point monitoring in areas close to the study area. The results obtained for the study area confirm that high erosion rates are a persistent environmental problem for the Upper Orcia Valley, which is not solved up to now, despite various land conservation interventions. The performed multi‐temporal analysis shows a slight decrease in the average water erosion rate during the last 60 years and a parallel increase in the frequency of mass wasting events. These variations are most likely related to a complex interplay between land use changes that have affected the study area during the studied period, revealing a very delicate equilibrium between farming activities and erosion processes.

Genetic Erosion – Examples from Italy<Superscript>1,2</Superscript>     

Karl?Hammer  Gaetano?LaghettiEmail author 《Genetic Resources and Crop Evolution》2005,52(5):629-634

Italy has been used as a country for estimating genetic erosion in crops. It was possible to compare early surveys (from the 1920s to the 1950s), especially on wheats, with results of later missions in the 1980s and 1990s. In the early years, a relatively high genetic erosion was observed (13.2% p.a.). From the 1950s until the 1980s erosion rates between 0.48 and 4% p.a. were estimated. In the little island of Favignana there was an erosion rate of 12.2% p.a. leading to the extinction of the last wheat landraces of this island. There have been no significant differences in erosion rates between field- and garden-crops though there has been the impression that garden crops are better preserved over the long run. Interestingly extinction rates of wild plants (0.13% in the Mediterranean) come close to the average erosion rates of crop plants in the area. ¹Dedicated to Erna Bennett on the occasion of her 80^th birthday ²Lecture presented during the XVII^th Congress of EUCARPIA in Tulln, Austria, 2004  相似文献   

Proposal to make the island of Linosa/Italy as a centre for on-farm conservation of plant genetic resources     

K. Hammer  G. Laghetti  P. Perrino 《Genetic Resources and Crop Evolution》1997,44(2):127-135

In view of the remarkable interest of the flora, vegetation and landscape of Linosa island, a natural reserve should be suggested including protection of the traditional agriculture. Especially for the last aim completely new ways have to be elaborated. An integrated approach of nature protection and on-farm conservation could be the ideal conclusion.  相似文献   

Active circulation of bluetongue vaccine virus serotype-2 among unvaccinated cattle in central Italy

Several seroconversions occurring in 2002 among sentinel cattle during the bluetongue-vaccination campaign in Lazio and Tuscany (central Italy) led to the suspicion of vaccine-virus circulation. Therefore in 2003, 17 seroconverting sentinel herds were investigated for the characteristics of the virus involved. From these farms, 91 unvaccinated animals and 57 Culicoides pools were tested for the presence of the bluetongue vaccine virus (serotype-2) or other strains. The presence of vaccine virus serotype-2 was confirmed by PCR followed by restriction analysis in the whole blood of 17 unvaccinated sentinel cattle and 12 pools of Culicoides imicola or C. obsoletus. Of the 17 herds, five were positive only for vaccine virus serotype-2, four were positive for other strains and two for both the vaccine and other strains; the remaining premises were virologicaly negative. The vaccine virus serotype-2 also was detected in areas not included in the vaccination campaign.  相似文献
