Nosocomial transmission of parainfluenza 3 virus in hematological patients characterized by molecular epidemiology
We report an outbreak of parainfluenza 3 virus involving 17 hematologyâoncology patients on 2 hospital wards. Sequence analysis of clinical samples confirmed homology of strains for 16/17 patients and 1 healthcare worker. Epidemiological analysis of the outbreak supported the molecular data with nosocomial transmission of the same genetic strain as the cause of the outbreak
Microbiota cloacal aerĂłbia de cracĂdeos cativos no Rio Grande do Sul e sua susceptibilidade a antimicrobianos Cloacal microbiota identification and evaluation of the antimicrobial resistance in captive cracids from Rio Grande do Sul, Brazil
Os cracĂdeos sĂŁo aves silvestres que habitam as matas tropicais da AmĂ©rica. Foram coletadas, no ano de 2007, amostras cloacais de 51 aves de dez espĂ©cies diferentes de cracĂdeos mantidos em cativeiros no Estado do Rio Grande do Sul. A partir dos swabs, colhidos assepticamente, foi realizado o isolamento e a caracterização bacteriana e o teste de susceptibilidade antimicrobiana dos isolados. Foram identificadas 93 cepas de bactĂ©rias. As bactĂ©rias mais frequentemente isoladas foram Escherichia coli, Staphylococcus spp. e Streptococcus spp. Todas as amostras foram negativas para o isolamento de Salmonella spp. O resultado do teste de sensibilidade mostrou que dentre as 93 cepas isoladas, todas foram sensĂveis apenas ao imipinem. Adicionalmente, os menores percentuais de resistĂȘncia foram observados frente ao cloranfenicol e ciprofloxacina. Os gĂȘneros e espĂ©cies bacterianas com maior percentual de resistĂȘncia a diferentes antibiĂłticos testados foram Escherichia coli, Serratia marcescens, Staphylococcus aureus e Streptococcus spp. Com os resultados obtidos no presente trabalho, concluĂ-se, que a população de cracĂdeos estudada apresenta sua microbiota cloacal composta por vĂĄrios gĂȘneros e espĂ©cies bacterianas e que a multirresistencia pode ser um problema no futuro, uma vez que algumas cepas isoladas mostraram percentuais elevados de resistĂȘncia a diferente antimicrobianos.<br>Cracids are wildlife Galliformes which inhabits the America's tropical forests. Fifty one cloacal swabs were collected from 10 different species of captive cracids from the Rio Grande do Sul State during 2007. The cloacal swab samples were submitted to bacterial isolation, identification and, subsequently; antimicrobial susceptibility testing. Ninety three bacterial isolates were obtained from the cracid population examined. The most prevalent among the isolates were Escherichia coli, and bacteria from the Staphylococcus and Streptococcus genera. All samples tested in this study were negative for Salmonella spp. The antimicrobial susceptibility tests showed that none of the 93 strains presented resistance to the antimicrobial imipinem. In addition, the lower percentages of resistance were observed against cloranfenicol and ciprofloxacine. The bacteria genus and species with the highest percentage of resistance to the different antimicrobials examined were E. coli, Serratia marcescens, Staphylococcus spp. and Streptococcus spp. In conclusion, the data presented in this article demonstrate that the cloacal microbiota of the reported cracid population is composed of several bacterial genera and species and multi-drug resistance may be a problem for the future, since some strains showed elevated percentage of resistance against several different antimicrobials
