    Background: Vector-borne zoonotic diseases are a concerning issue in Europe. Lyme disease and tick-borne encephalitis virus (TBEV) have been reported in several countries with a large impact on public health; other emerging pathogens, such as Rickettsiales, and mosquito-borne flaviviruses have been increasingly reported. All these pathogens are linked to wild ungulates playing roles as tick feeders, spreaders, and sentinels for pathogen circulation. This study evaluated the prevalence of TBEV, Borrelia burgdorferi sensu lato, Rickettsia spp., Ehrlichia spp., and Coxiella spp. by biomolecular screening of blood samples and ticks collected from wild ungulates. Ungulates were also screened by ELISA and virus neutralization tests for flaviviral antibody detection. Results: A total of 274 blood samples were collected from several wild ungulate species, as well as 406 Ixodes ricinus, which were feeding on them. Blood samples tested positive for B. burgdorferi s.l. (1.1%; 0-2.3%) and Rickettsia spp. (1.1%; 0-2.3%) and showed an overall flaviviral seroprevalence of 30.6% (22.1-39.2%): 26.1% (17.9-34.3%) for TBEV, 3.6% (0.1-7.1%) for Usutu virus and 0.9% (0-2.7%) for West Nile virus. Ticks were pooled when possible and yielded 331 tick samples that tested positive for B. burgdorferi s.l. (8.8%; 5.8-11.8%), Rickettsia spp. (26.6%; 21.8-31.2%) and Neoehrlichia mikurensis (1.2%; 0-2.4%). TBEV and Coxiella spp. were not detected in either blood or tick samples. Conclusions: This research highlighted a high prevalence of several tick-borne zoonotic pathogens and high seroprevalence for flaviviruses in both hilly and alpine areas. For the first time, an alpine chamois tested positive for anti-TBEV antibodies. Ungulate species are of particular interest due to their sentinel role in flavivirus circulation and their indirect role in tick-borne diseases and maintenance as Ixodes feeders and spreaders

    Toxicity, Tunneling and Feeding Behavior of the Termite, Coptotermes vastator, in Sand Treated with Oil of the Physic Nut, Jatropha curcas

    Oil of the physic nut, Jatropha curcas L. (Malpighiales: Euphorbiaceae), was evaluated in the laboratory for its barrier and repellent activity against the Philippine milk termite Coptotermes vastator Light (Isoptera: Rhinotermitidae). The study showed that J. curcas oil had anti-feeding effect, induced reduction in tunneling activity and increased mortality in C. vastator. Behavior of termites exposed to sand treated with J. curcas oil indicated that it is toxic or repellent to C. vastator. Toxicity and repellent thresholds, were higher than those reported for other naturally occurring compounds tested against the Formosan subterranean termite

    Health sciences define alcoholism as a multifaceted syndrome. Guidelines for treatment include adoption of the harm reduction paradigm and the essential role of Primary Health Care (PHC) towards the wide range of alcohol problems. This research aimed at understanding the social representations of alcoholism constructed by Brazilian PHC professionals, working at Family Health Centers (FHC). We conducted semi-structured interviews with 40 graduated health professionals who worked in 11 different FHC located in a municipality in southeast Brazil. Data were treated with thematic content analysis. We highlight the following results: professionals objectified the alcoholic as a patient who did not search for treatment and/or who threatened the normal functioning of the FHC; professionals considered social and psychological factors as the main causes of alcoholism; they did not mention the concept of harm reduction, nor well-defined treatment protocols. The causal attribution and the representational field inherent to the social representations contributed to anchor alcoholism as a "plague" of poverty. The FHC were perceived simultaneously as important and impotent towards alcoholism. We conclude that the implementation of alcohol-related care strategies must consider the intergroup relations between professionals and patients

    The Internationalization of Psychology Journals in Brazil: A Bibliometric Examination Based on Four Indices

    Abstract: There is considerable variability among psychology journals in Brazil, in terms of presence on the international stage. However, research as to why is very scarce. This study empirically examined the relationship between several indices of internationalization and real-world internationalization, among these journals. 661 articles from the top-17 psychology journals in Brazil were coded for: English-language text, editorial board makeup, lead author institution, and article type. Analyses revealed that successful internationalization was associated with: (i) lead author institution from a native English-speaking country; (ii) empirical articles; and (iii) editorial board members from a native English-speaking country. Use of English-language text was not associated with successful internationalization. These findings suggest that the path to internationalization for psychology journals in Brazil may depend on increased publishing of findings from English-speaking countries; or at the very least: increased collaboration between Brazilian and native English-speaking scholars
