ABSTRACT
Dissemination of Acinetobacter baumannii strains in different units of a hospital in Sorocaba, Sao 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 percent) 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 percent and 84.8 percent of the strains isolated in 1993 and in 1994, respectively

As doenças oculares externas agudas constituem parte significativa do atendimento de qualquer serviço oftalmológico. Através de um estudo prospectivo, os autores fizeram um levantamento epidemiológico das patologias oculares externas atendidas no serviço, ressaltando os resultados de cultura e de sensibilidade antibiótica.

Foram estudadas 190 cepas de Acinetobcter (76 isoladas de líquido cefalorraquidiano, 30 de sangue e 84 de outros materiais clínicos), isoladas no período 1986-92, em Säo Paulo, Brasil. As espécies foram identificadas segundo Bouvet and Grimont e Vouvet and Jeanjean. Os sorotipos e biotipos foram determinados para A. baumannii seguindo os métodos descritos por Traub e Bouvet and Grimont, respectivamente. Entre as 10 espécies identificadas, o A.baumannii (60 por cento) e A.genospecies 3 (11.6 por cento) foram as mais frequentes. Verificou-se que os biotipos 2,6, e 9 e os sorotipos 04, 015 e 029 foram predominantes entre as cepas de A.baumannii
