Biotipagem, sorotipagem e ribotipagem na avaliação epidemiológica de A. baumannii em unidades hospitalares, Sorocaba, São Paulo, Brasil

Dissemination of Acinetobacter baumannii strains in different units of a hospital in Sorocaba, São Paulo, Brazil was evaluated over a period of two years. By using biotyping, serotyping and ribotyping, 27 distinct clones were differentiated among 76 strains isolated between 1993-94, from clinical specimens of hospitalized patients. Two clones, 2:O4:A (biotype:serotype:ribotype) and 2:O29:A accounted for the majority of strains widely disseminated in the units during 1993. The introduction in the hospital setting, of a new clone, 6:O13:B, at the end of 1993 and its predominance through 1994 is discussed. Among 15 strains isolated from neonates, 6 (40%) belonged to the same clone, 2:O4:A. Interestingly, this clone was almost all recovered in neonatal intensive care unit, nursery and in pediatric unit. All strains were susceptible to imipenem and polymyxcin B. Multiresistant strains (up to 12 antimicrobial agents) accounted for 66.7% and 84.8% of the strains isolated in 1993 and in 1994, respectively.Foi avaliada a disseminação, durante um período de dois anos, de cepas de Acinetobacter baumannii em diferentes unidades de um hospital de Sorocaba, São Paulo.Usando as técnicas de biotipagem, sorotipagem e ribotipagem, as 76 cepas isoladas no período 1993-94, foram diferenciadas em 27 distintos clones. Dois clones, 2:O4:A (biotipo:sorotipo:ribotipo) e 2:O29:A predominaram, em 1993, entre as cepas disseminadas nas várias unidades. Observou-se no final de 1993, a introdução de um novo clone, 6:O13:B e a sua predominância em 1994. Entre as 15 cepas isoladas de recém nascidos, 6 (40%) pertenciam ao mesmo clone, 2:O4:A . A maioria das cepas desse clone foram isoladas da unidade de terapia intensiva neonatal, de berçário e de unidades pediátricas. Quanto à resistência aos agentes antimicrobianos, todas as cepas foram sensíveis à polimixina B e ao imipenen. Em 1993, 66,7% das cepas eram multi-resistentes (resistentes de 4 a 12 dos 15 antimicrobianos testados), enquanto que, em 1994, 84,8% das 46 cepas isoladas foram multi-resistentes a mais de 4 e até a 12 drogas

Professores e Alunos: o engendramento da violência da escola

The school violence engendering is partially analyzed, considering the violence production in the school environment. This is a bibliographic research with quantitative and qualitative approach. Sources: 77 theses and 15 dissertations carried out in Brazil (2007 to 2012). Data collection and organization: Content Analysis. Main reference: Bernard Charlot and Pierre Bourdieu. Results: the sources showed that Brazilian teachers participate effectively in the school violence engendering, contributing to violence production in the school environment. The students are the main victims. The teacher is less affected by physical and verbal violence. The symbolic power is the most perpetrated by the teacher against the student. The school also plays a major role in it.Analisa-se o engendramento de uma face da violência da escola, tendo em vista a produção da violência em espaço escolar. Pesquisa bibliográfica quanti-qualitativa. Fontes: 77 dissertações e 15 teses produzidas no Brasil (2007 a 2012). Coleta e organização dos dados: Análise de Conteúdo. Fundamentação base: Bernard Charlot e Pierre Bourdieu. Resultados: as fontes apontaram que professores brasileiros são protagonistas na constituição da violência da escola, contribuindo para a produção da violência em espaço escolar. Os alunos são as principais vítimas dessa violência. O professor sofre menos violência física e verbal do que o aluno. A violência simbólica é a mais usada pelo professor contra o aluno. A escola também usa desse expediente
