Foi realizado um levantamento sobre uso de psicotrópicos entre estudantes da Faculdade Ciências Saúde Universidade Federal do Amazonas, Manaus, Brasil, em uma amostra 521 alunos. O "uso na vida" álcool foi relatado por 87,7% dos (IC95%: 85,34-90,06) e o tabaco 30,7% (IC 95%: 27,39-34,01), sendo último maior sexo masculino (39,7%; IC95%: 33,33-46,01). As substâncias ilegais mais usadas foram: solventes (11,9%; 9,57-14,23), maconha (9,4%; 7,30-11,50), anfetamínicos ansiolíticos (ambos com...
Enterobacter cloacae and E. aerogenes have been increasingly reported as important opportunistic pathogens. In this study, a high prevalence of multi-drug resistant isolates from Brazil, harboring several β-lactamase encoding genes was found. Several virulence were observed in aerogenes, contrasting with the which presented none.
Typing methods to evaluate isolates in relation their phenotypical and molecular characteristics are essential epidemiological studies. In this study, Candida albicans biotypes were determined before after storage order verify stability. Twenty C. typed by Randomly Amplified Polymorphic DNA (RAPD), production of phospholipase proteinase exoenzymes (enzymotyping) morphotyping 180 days Sabouraud dextrose agar (SDA) sterilised distilled water. Before the storage, 19 RAPD patterns, two...
A capacidade de Cryptococcus spp produzir melanina em meios contendo compostos fenólicos é amplamente utilizada na identificação destas espécies no laboratório. O objetivo do presente trabalho foi comparar a produção desse pigmento quatro cultura por sp. Foram testadas 16 cepas neoformans, 17 albidus, 13 laurentii, e 2 uniguttulatus nos meios: ágar batata cenoura, alpiste, semente girassol L-dopa. avaliada com base pigmentação das colônias, demonstrada 5 dias incubação 93,8% neoformans Dos...
Summary The wide spectrum of candidiasis and its clinical importance encourage the research with purpose clarifying mechanisms pathogenicity identification virulence factors Candida sp . Therefore, aim this study was to verify adhesion capacity, protease activity genotypic diversity oral C. albicans tropicalis isolates. ability extracellular matrix glycoproteins laminin fibronectin evaluated using ELISA technique. proteases carried out in agar plate containing bovine albumin through a...
ABSTRACT The extracts and fractions of leaves branches Protium hebetatum D. C. Daly (Burseraceae) were investigated for their antibacterial activity chemical composition. methanol extract (EMG) was considered active against the Escherichia coli Proteus vulgaris, showing an inhibition zone 13 mm, selected bioassay-guided phytochemical fractionation. From technique broth microdilution, a moderate inhibitor Staphylococcus aureus, Pseudomonas aeruginosa Enterococcus faecalis, with minimum...
Various organisms have been characterized by molecular methods, including fungi of the genus Cryptococcus. The purposes this study were: to determine discriminatory potential RAPD (Random Amplified Polymorphic DNA) primers, pattern similarity Cryptococcus species, and discuss their useful application in epidemiological studies. We analyzed 10 isolates each specie/group: C. albidus, laurentii complex, neoformans var. grubii, all from environmental source, two ATCC strains, grubii 90112, 28957...
Abstract Klebsiella pneumoniae is an opportunistic pathogen that can cause several infections, mainly in hospitalised or immunocompromised individuals. The spread of K. emerging virulent and multidrug-resistant clones a worldwide concern its identification crucial to control these strains especially hospitals. This article reports data related multi-resistant strains, isolated from inpatients the city Manaus, Brazil, harbouring virulence antimicrobial resistance genes, including high-risk...
Este trabalho visou o desenvolvimento de sistemas microfluídicos para complexação eletrostática entre nanopartículas lipídica sólidas (SLNs) e DNA aplicações em terapia gênica. As SLNs possuem um núcleo hidrofóbico composto por lipídeos sólidos a temperatura ambiente, que são estabilizados tensoativos. A eficiência incorporação das células é afetada pelo tamanho polidispersidade dos complexos catiônicas. Técnicas convencionais frequentemente geram não adequados biologicamente. Por outro...
Cryptococcus laurentii is a rare human pathogen ubiquitous in nature. This study aims to evaluate the disk diffusion method for testing fluconazole susceptibility of C. laurentii, and moreover, assess minimal fungicidal concentration (MFC) by broth microdilution method. Eleven isolates environmental complex were employed determine methods according CLSI (Clinical Laboratory Standards Institute) guidelines MFC technique. Thedisk indicated four susceptible, three susceptible-dose dependent...
