The map appearance and analysis of corresponding data may both depend on a map projection used to transform the 3-dimensional world onto a 2-dimensional surface. Map projections necessarily introduce bias - an issue that has not received full attention in the literature. This study aims to demonstrate the impact map projections can have on spatial analysis and disease maps for public health. Case studies applied varying map projections, including the Lambert, Mercator and Robinson projections, to Israel, North Carolina and Southern Ontario as study areas. The effect of projections on various measures, estimates, tests and models was assessed. When the map projection was changed: (i) a distance in Israel increased by 30%; (ii) for Southern Ontario an areal size increased by almost 95%; Moran's I test switched from significant to not; and (iii) a single disease cluster in North Carolina converted into three distinct clusters. Visual bias in disease mapping is unavoidable and should be recognized. Disease maps and spatial analytical inferences, including disease clusters should be reported with their geographic projection. Using geographic coordinates can prevent analytical bias.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":"60 4","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142373003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geographic epidemiology is the study of spatial patterns of population health in a study area. Such spatial patterns (trend, cluster and clustering) require clear definition to be meaningful in science communication. However, the term \"disease cluster\" has been defined in the literature in various and rather different ways. When geographic epidemiology is unable to make sense of its own concepts it is questionable how respective research results can benefit one health. The goal of this study was to clarify the disease cluster concept. Examples of disease cluster definitions from the literature were used for illustration. The epidemiological triangle of causation (agent, host and environment) was used to conceptualize geographic epidemiological data analysis. The term disease cluster was distinguished from related concepts (clustering, high-risk area, hot spot and outbreak) additionally the semantics and statistical meaning of expectation and prediction were reviewed to further identify the cluster concept as a statistical outlier. The new paradigm of the geographic epidemiological trillium is proposed here and embedded within the spatial generalized linear mixed model to clarify concepts of spatial patterns and guide epidemiological research and teaching.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":"60 4","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142373002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was designed to evaluate the thermo-stability of a live-attenuated ND virus vaccine containing the Mukteswar strain and to genetically characterize the seed virus. Moreover, the presence of extraneous agents (Fowl adenovirus, Mycoplasma, Salmonella Pullorum, and Salmonella Gallinarum) was assessed using polymerase chain reactions (PCR) optimized for detection in a panel. The vaccine was evaluated for its potency and efficacy after storage at 4°C, 25°C and 37°C for 36, 48, 96 and 144 hours. A total of 100 commercial broiler chickens were randomly divided into six groups and immunized with the vaccine stored at specified temperatures for the given times. Blood samples were collected on days 0, 7, 14, 21 and 28 post-vaccination, sera were separated and antibody titers were assessed using hemagglutination inhibition (HI) assay. The data were analyzed by two-way analysis of variance (ANOVA) and multivariate analysis of variance (MANOVA). Reverse-transcription PCR targeting the F gene of Newcastle disease virus (NDV) and subsequent sequence analysis confirmed the presence of NDV in the vaccine seed (deposited to GenBank Acc. Nos. MK310260 and MK310261). Phylogenetic analysis revealed a close resemblance of the vaccine virus with other Avian Avulaviruses (NDV class II Genotype III viruses and more specifically with NDV Mukteswar vaccine strains), yet it was distinct from NDV class II Pakistani field isolates, which grouped into genotype XIII.2.1. The PCR testing confirmed that the vaccine was free from extraneous agents. The present study's findings propose an alternative rapid PCR-based method to evaluate the purity of NDV live vaccines. Together these data suggest that the tested vaccine is pure, potent and efficacious, yet continuous maintenance of the cold chain for vaccine storage is recommended to maintain its potency and efficacy.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":"59 3","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142296598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One gravid female and three adult males were inoculated with a suspension containing 1×106 CFU/mL (colony-forming units) of B. suis biovar 1 by oral route. In addition, the gravid female and one male received the same suspension by the conjunctival route. A young male and two females not inoculated were kept in contact with the animals inoculated.

Of the three uninoculated animals, one female was seropositive for Brucella infection. Brucella was isolated from the spleen, liver, mesenteric lymph nodes, uterus, testes, and urine. Characteristic histologic lesions were found in the epididymis. These results suggest that armadillos can act as a reservoir for the spread of B. suis infection, and the persistence of Brucella in armadillo tissues constitutes a risk for humans, because of the cultural practice of armadillo meat consumption in rural communities.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":"60 3","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141907729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such a context, a timely, accurate, and reliable flow of information, aimed both at the population and at stakeholders, is crucial for establishing a proper dialogue between institutions and people, driving the empowerment of citizens. To address this crisis, the Italian Government introduced Law 6 of 2014, establishing a multidisciplinary Working Group tasked with identifying and mapping the sites affected by spills and illegal disposal in the territory. The TdF-WG defined a scientific methodology for classifying these sites in terms of prohibition on the cultivation of specific crops, consequently allowing the adoption of appropriate clean up and restoration measures for the impacted sites.

Phylogenetic analysis of the CPV-2c sequences revealed clustering with Singaporean, South Korean, Mongolian and Bangladeshi dog 2c sequences. Phylogenetic analysis of the 2a isolate (MZC 2) was found to be clustered with Indian, Thai and Singaporean dog 2a isolates. Similarly, all the four FPV sequences were ancestrally related to Indian dog and cat FPV sequences hinting towards interspecies transmission between dogs and cats. Both synonymous and non-synonymous mutations were evident in CPV-2c, 2a and FPV sequences indicative of active evolution. In cell culture medium, CPV-2 showed cytopathogenic effects at the third passage level.
