BACKGROUND AND PURPOSE To evaluate the impact of 23-valent polysaccharide pneumococcal vaccine on Streptococcus pneumoniae colonization in the upper airway of patients with human immunodeficiency virus (HIV)-1 in Taiwan. METHODS 302 HIV-infected patients aged 15 years or older underwent swab cultures of the posterior pharynx and tonsils for S. pneumoniae between June 1, 2000 and June 30, 2002...
We have previously reported on the induction, in mice, of a systemic (splenic) immune response with IgA as the dominant antibody, as a result of a short (4 day) intragastric immunization course with foreign erythrocytes. This response was followed by a prolonged period of hyporesponsiveness to similarly administered antigen. Here it is shown that this hyporesponsiveness is also manifested towar...
Background: Fungal infections with high morbidity and mortality in neonatal intensive care unit are usually preceded by colonization. We aimed to investigate the prevalence of fungal colonization, determine the risk factors and health outcome such as any change in the patient's improvement in hospitalized infants of Neonatal Intensive Care Unit (NICU). <e...
Introduction: To date, many vaccines have been developed for anthrax but not yet an ideal vaccine. In this study, chimeric protein containing domain 1 lethal factor and domain 4 protective antigens of Bacillus anthracis in copolymer nanocapsules were used to solve the problems caused by existing vaccines and to increase the efficiency of the proposed vaccine. Materials and Methods: In this expe...
background: enterotoxigenic escherichia coli (etec) strains are the major causes of diarrheal disease in humans and animals. colonization factors and enterotoxins are the major virulence factors in etec pathogenesis. for the broad-spectrum protection against etec, one could focus on colonization factors and non-toxic heat labile as a vaccine candidate. methods: a fusion protein is composed of a...
background: inherited thrombophilic gene polymorphisms have been related to the pathogenesis of venous thromboembolism and its outcomes. considering the scarcity of data on the frequency of the thrombophilic gene polymorphisms in iranian populations, the aim of this study was to assess such polymorphisms in healthy individuals. materials and methods: this cross-sectional study was performed on ...
BACKGROUND Immunoglobulin A (IgA) in maternal milk may protect Gambian infants from early Helicobacter pylori colonization. This study sought evidence that this protection could be due to specific IgA antibodies. METHODS Sixty-five infants were screened from 12 weeks of age with [13C]-urea breath tests. Antibodies in maternal milk were measured to determine total IgA content and to detect spe...
Background and purpose: Invasive candidiasis in infants has high mortality rate and is often associated with colonization on medical devices such as catheters. Candida colonization is considered as a predisposing factor for Candida related infection. The aim of this study was to evaluate the rate of catheters infectivity by Candida species. Materials and methods: In this descriptive cross-sect...
