The prevalence of mutations at amino acid (aa) position 315 in the katG gene of isoniazid (INH)-resistant Mycobacterium tuberculosis isolates in The Netherlands and the mutation's association with the level of INH resistance, multidrug resistance, and transmission were determined. Of 4288 M. tuberculosis isolates with available laboratory results, 295 (7%)(More)
A homemade enzyme-linked immunosorbent assay (ELISA) (Academic Medical Center ELISA [AMC-ELISA]) and a dipstick assay for the detection of anti-Strongyloides stercoralis antibodies in serum were developed and evaluated together with two commercially available ELISAs (IVD-ELISA [IVD Research, Inc.] and Bordier-ELISA [Bordier Affinity Products SA]) for their(More)
We prospectively studied 3,791 children hospitalized during 2011 during a large outbreak of enterovirus 71-associated hand, foot, and mouth disease in Vietnam. Formal assessment of public health interventions, use of intravenous immunoglobulin and other therapies, and factors predisposing for progression of disease is needed to improve clinical management.
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 Dengue is a major global public health problem with increasing incidence and geographic spread. The epidemiology is complex with long inter-epidemic intervals and endemic with seasonal fluctuations. This study was initiated to investigate dengue transmission dynamics in Binh Thuan province, southern Vietnam. METHODOLOGY Wavelet analyses were(More)
Antimicrobial consumption is one of the major contributing factors facilitating the development and maintenance of bacteria exhibiting antimicrobial resistance. Plasmid-mediated quinolone resistance (PMQR) genes, such as the qnr family, can be horizontally transferred and contribute to reduced susceptibility to fluoroquinolones. We performed an(More)
BACKGROUND Infectious diseases of the central nervous system (CNS) remain common and life-threatening, especially in developing countries. Knowledge of the aetiological agents responsible for these infections is essential to guide empiric therapy and develop a rational public health policy. To date most data has come from patients admitted to tertiary(More)
Patient 1: A 77-y-old male from Ho Chi Minh City (HCMC), Viet Nam, with a history of (compensated) cirrhosis and noninsulin-dependent diabetes, presented to a district hospital with a 3-d history of fever and headaches, followed by uncon-sciousness. A lumbar puncture (LP) was performed (Table 1), and he was diagnosed with clinically suspected bacterial(More)
BACKGROUND Inappropriate antibiotic use for acute respiratory tract infections is common in primary health care, but distinguishing serious from self-limiting infections is difficult, particularly in low-resource settings. We assessed whether C-reactive protein point-of-care testing can safely reduce antibiotic use in patients with non-severe acute(More)
Since their emergence as avian (1996) and zoonotic human pathogens (1997), H5N1 influenza viruses have become endemic among poultry in large parts of Asia, but outbreaks have also been seen in Africa and Europe. Transmission from animals to humans remains sporadic, but mortality of human infection is high (63%). To date, reported cases of human to human(More)
