Abstract
Migratory birds have contributed to the dissemination of multidrug-resistant (MDR) bacteria across the continents. A CTX-M-2-producing Escherichia coli was isolated from a black skimmer (Rynchops niger) in Southeast Brazil. The whole genome was sequenced using the Illumina NextSeq platform and de novo assembled by CLC. Bioinformatic analyses were carried out using tools from the Center for Genomic Epidemiology. The genome size was estimated at 4.9 Mb, with 4790 coding sequences. A wide resistome was detected, with genes encoding resistance to several clinically significant antimicrobials, heavy metals, and biocides. The blaCTX-M-2 gene was inserted in an In229 class 1 integron inside a ∆TnAs3 transposon located in an IncHI2/ST2 plasmid. The strain was assigned to ST5506, CH type fumC19/fimH32, serotype O8:K87, and phylogroup B1. Virulence genes associated with survival in acid conditions, increased serum survival, and adherence were also identified. These data highlight the role of migratory seabirds as reservoirs and carriers of antimicrobial resistance determinants and can help to elucidate the antimicrobial resistance dynamics under a One Health perspective.

Abstract
OBJECTIVES The incidence of multidrug-resistant bacteria in wildlife animals has been investigated to improve our knowledge of the spread of clinically relevant antimicrobial resistance genes. The aim of this study was to report the first draft genome sequence of an extensively drug-resistant (XDR) Pseudomonas aeruginosa ST644 isolate recovered from a Magellanic penguin with a footpad infection (bumblefoot) undergoing rehabilitation process. METHODS The genome was sequenced on an Illumina NextSeq® platform using 150-bp paired-end reads. De novo genome assembly was performed using Velvet v.1.2.10, and the whole genome sequence was evaluated using bioinformatics approaches from the Center of Genomic Epidemiology, whereas an in-house method (mapping of raw whole genome sequence reads) was used to identify chromosomal point mutations. RESULTS The genome size was calculated at 6436450bp, with 6357 protein-coding sequences and the presence of genes conferring resistance to aminoglycosides, β-lactams, phenicols, sulphonamides, tetracyclines, quinolones and fosfomycin; in addition, mutations in the genes gyrA (Thr83Ile), parC (Ser87Leu), phoQ (Arg61His) and pmrB (Tyr345His), conferring resistance to quinolones and polymyxins, respectively, were confirmed. CONCLUSION This draft genome sequence can provide useful information for comparative genomic analysis regarding the dissemination of clinically significant antibiotic resistance genes and XDR bacterial species at the human-animal interface.

Abstract
Magellanic penguins (Spheniscus magellanicus) routinely migrate from their breeding colonies to Southern Brazil often contracting diseases during this migration, notably avian malaria, which has been already reported in Brazil and throughout the world. Detection of Plasmodium spp. in blood smears is the routine diagnostic method of avian malaria, however it has a low sensitivity rate when compared to molecular methods. Considering the negative impact of avian malaria on penguins, the aim of this study was to detect the presence of Plasmodium spp. in Magellanic penguins using Polymerase Chain Reaction (PCR) and by verifying clinical, hematological, and biochemical alterations in blood samples as well as to verify the likely prognosis in response to infection. Blood samples were obtained from 75 penguins to determine packed cell volume (PCV), red blood cell (RBC) and white blood cell (WBC) counts, mean corpuscular volume (MCV), uric acid, total protein, albumin, globulin and aspartate aminotransferase (AST) activity levels. Whole blood samples were used for PCR assays. Plasmodium spp. was detected in 32.0% of the specimens using PCR and in 29.3% using microscopic analyses. Anorexia, diarrhea and neurological disorders were more frequent in penguins with malaria and a significant weight difference between infected and non-infected penguins was detected. PCV and MCV rates showed no significant difference. RBC and WBC counts were lower in animals with avian malaria and leukopenia was present in some penguins. Basophil and lymphocyte counts were lower in infected penguins along with high monocyte counts. There was no significant difference in AST activities between infected and non-infected animals. There was a significant increase in uric acid values, however a decrease in albumin values was observed in infected penguins. Based on this study, we concluded that Plasmodium spp. occurs in Magellanic penguins of rehabilitation centers in Southeastern Brazil, compromising the weight of infected animals with clinical alterations appearing in severe cases of this disease. It was also noted that, although the hematological abnormalities presented by these animals may not have been conclusive, leukopenia, monocytosis and the decrease of basophils and lymphocytes revealed an unfavorable prognosis, and Plasmodium spp. infections may progress with elevated uric acid concentration and low albumin levels.

Abstract
During paediatric dental treatment, non-collaboration and fearful reactions are frequently observed in the child client. The dentistry student must be prepared to cope with these reactions, particularly considering the importance of the relationship between dentists and patients in the promotion of oral health. The present study aimed to assess undergraduate dentistry students' perceptions of their ability to cope with non-collaboration situations in paediatric dentistry. A Likert-style questionnaire was used to analyse students' self-confidence levels, and proposed solutions to 10 problem situations the students would be likely to encounter were recorded. The questionnaire was administered to two undergraduate dentistry student groups from two different Brazilian Public Faculties, comprising 122 respondents. The self-confidence analysis indicated that it varied according to the extent of the child's reaction and the invasiveness of the procedure. Responses to the open-ended questions were categorised by solution proposed, and the analysis indicated that the most frequent responses were categorised as follows: tranquilising, explanation and restriction. Significant differences were found in tranquilising (with higher values for Faculty 2 than 1, and higher values for female students than male students at Faculty 2) and restriction (with higher values for female students compared with male student at both Faculties). The results and discussion focused on the aspects of training dentistry students' social and behavioural management skills.

Abstract
Foi realizado estudo transversal de utilização de serviços de saúde no Distrito Sanitário de Pau da Lima, Salvador, Bahia, Brasil, em 1992, a partir de inquérito domiciliar com recurso à técnica de amostragem por conglomerados. Entre as 1887 pessoas moradoras dos 384 domicílios visitados, 236 haviam utilizado serviços de saúde nos últimos 30 dias, correspondendo à taxa global de utilização de 12,5%. Os serviços públicos do distrito foram responsáveis por 25,9% do total dos atendimentos, tendo ocorrido maior utilização na faixa etária entre 15 e 29 anos (29,8%) e no sexo feminino (73,7%). A escolha do tipo de serviços foi influenciada principalmente por razões relacionadas com a acessibilidade (63,7%). A procura dos serviços decorreu sobretudo de motivos relacionados com a ocorrência de doença e com a busca de serviços curativos (75,7%). Esses achados revelam incipiência no processo de distritalização, expresso tanto em insuficiências quantitativas relacionadas com a cobertura assistencial e a oferta de serviços, quanto em problemas organizacionais que fazem com que a produção ainda não utilize preferencialmente os serviços do Distrito. Os autores discutem esses resultados no atual contexto de expansão do setor privado e de colapso de financiamento setorial.
