BACKGROUND Recent outbreaks of avian influenza A (H5N1) in poultry throughout Asia have had major economic and health repercussions. Human infections with this virus were identified in Vietnam in January 2004. METHODS We report the clinical features and preliminary epidemiologic findings among 10 patients with confirmed cases of avian influenza A (H5N1)(More)
Influenza A (H5N1) virus with an amino acid substitution in neuraminidase conferring high-level resistance to oseltamivir was isolated from two of eight Vietnamese patients during oseltamivir treatment. Both patients died of influenza A (H5N1) virus infection, despite early initiation of treatment in one patient. Surviving patients had rapid declines in the(More)
In southern Vietnam, a four-year-old boy presented with severe diarrhea, followed by seizures, coma, and death. The cerebrospinal fluid contained 1 white cell per cubic millimeter, normal glucose levels, and increased levels of protein (0.81 g per liter). The diagnosis of avian influenza A (H5N1) was established by isolation of the virus from cerebrospinal(More)
BACKGROUND The dominant viral etiologies responsible for acute respiratory infections (ARIs) are poorly understood, particularly among hospitalized children in resource-limited tropical countries where morbidity and mortality caused by ARIs are highest. Improved etiological insight is needed to improve clinical management and prevention. OBJECTIVES We(More)
BACKGROUND Southeast Asia has the most resistant malaria parasites in the world, which severely limits treatment options. There is general acceptance that to combat resistance, combinations of antimalarial drugs that include an artemisinin derivative should be used, and, if possible, these should be formulated in a single tablet. METHODS We did a pilot(More)
In an earlier study, biocatalytic carbon oxyfunctionalization with water serving as oxygen donor, e.g., the bioconversion of quinaldine to 4-hydroxyquinaldine, was successfully achieved using resting cells of recombinant Pseudomonas putida, containing the molybdenum-enzyme quinaldine 4-oxidase, in a two-liquid phase (2LP) system (Ütkür et al. J Ind(More)

Detection limits for Campylobacter jejuni strains JH93 and ATCC 29428 in a new blood-free enrichment broth (BFEB) were investigated under aerobic conditions. Cultures of Camp. jejuni were inoculated into 50 ml BFEB containing 10% food homogenate in 50 ml screw-cap tubes. After 24 h enrichment under aerobic conditions, Camp. jejuni were isolated on four(More)
Synopsis The adequacy of preservation of seven previously unopened commercial cosmetic products was tested by individual challenges with Aspergillus niger ATCC 9642, Candida albicans ATCC 10231, Escherichia coli ATCC 8739, Pseudomonas aeruginosa ATCC 15422, and Staphylococcus aureus ATCC 6538, using the Cosmetic, Toiletry, and Fragrance Association (CTFA)(More)
Synopsis A direct contact membrane inoculation technique for yeasts and moulds was used to evaluate the preservation efficacy and antimicrobial activity of Germall 115 and Germall II in pressed eye shadows. Test organisms on membrane filters were placed in direct contact with cosmetics at room temperature under humid conditions. Growth on membranes was(More)

Recovery limits were evaluated for Campylobacter jejuni in an existing Food and Drug Administration (FDA) enrichment broth (EB) formula supplemented with Oxyrase enzyme. Cultures of Camp. jejuni were inoculated into EB or EB containing 10% raw milk, raw oysters, crabmeat or mushrooms. After 24 and 48 h of enrichment, Camp. jejuni was isolated on four(More)
