Patagonia in southern South America is among the few world regions where direct human impact is still limited but progressively increasing, mainly represented by tourism, farming, fishing and mining activities. The sanitary condition of Patagonian wildlife is unknown, in spite of being critical for the assessment of anthropogenic effects there. The aim of this study was the characterization of Salmonella enterica strains isolated from wild colonies of Magellanic penguins (Spheniscus magellanicus) located in Magdalena Island and Otway Sound, in Chilean Patagonia. Eight isolates of Salmonella were found, belonging to Agona and Enteritidis serotypes, with an infection rate of 0·38%. Resistance to ampicillin, cefotaxime, ceftiofur and tetracycline antimicrobials were detected, and some of these strains showed genotypic similarity with Salmonella strains isolated from humans and gulls, suggesting inter-species transmission cycles and strengthening the role of penguins as sanitary sentinels in the Patagonian ecosystem.
Abstract.-We report the mass stranding of 46 false killer whales in the Strait of Magellan in February 2013. We present observation-based information about body size, sex, dental formula and necropsies. Sexual dimorphism in body length was clear, with males being significantly larger than females. Dental formula coincided with previous reports for the species, with asymmetry present in females. Individuals showed normal body conditions without any signs of apparent disease. The cause of the stranding remains unknown, however the coastal morphology hypothesis is a possible explanation.
Este artigo apresenta uma análise dos testemunhos de sobreviventes ao desastre ocorrido em 2011, no Vale do Cuiabá (Petrópolis, RJ), região serrana do Estado do Rio de Janeiro, a partir de uma abordagem psicossocial. Os testemunhos foram coletados sete anos após a tragédia por meio de entrevistas individuais e grupais e mostram que o desastre continua. Dentre os resultados, evidencia-se que as pessoas entrevistadas se percebem como sobreviventes e não como afetados, atingidos ou vítimas; a vivência do abandono permanece com a ausência do Estado; e a precariedade das políticas públicas praticadas fragmentaram as relações comunitárias, gerando comprometimento da comunicação interpessoal. Destaca-se que o desastre permanece enquanto durar o sofrimento social dos envolvidos e que os profissionais que atuam nesse campo necessitam desenvolver uma escuta qualificada.
