Identification of P1 types and variants of Mycoplasma pneumoniae during an epidemic in Chile
(2010)
This study was conducted to determine the types of M. pneumoniae prevalent in adults presenting with community-acquired pneumonia during an epidemic period, and to scrutinize a variable region of the RepMP4 element for the ...
Trimethoprim resistance in enterobacteria isolated in Chile
(1989)
Four hundred strains of enterobacteria, isolated before the introduction of trimethoprim as a single agent in Chile, were studied. One hundred and thirty six strains (34%) were resistant to ≥8 mg/l of trimethoprim and 118 ...
Glucose and ethanol-dependent transcriptional regulation of the astaxanthin biosynthesis pathway in Xanthophyllomyces dendrorhous
(2011)
Background: The yeast Xanthophyllomyces dendrorhous is one of the most promising and economically attractive natural sources of astaxanthin. The biosynthesis of this valuable carotenoid is a complex process for which the ...
Effect of supplementation with an iron-fortified milk on incidence of diarrhea and respiratory infection in urban-resident infants
(Informa Healthcare, 1995)
To address the hypothesis that increased infectious morbidity is associated with iron supplementation, 783 randomly selected infants were provided with a powdered full fat cow's milk (non-fortified group). and 872 with a ...
Multiplex PCR for Diagnosis of Enteric Infections Associated with Diarrheagenic Escherichia coli
(2004)
A multiplex PCR for detection of three categories of diarrheagenic Escherichia coli was developed. With this method, enterohemorrhagic E. coli, enteropathogenic E. coli, and enterotoxigenic E. coli were identified in fecal ...
Nosocomial transmission of rotavirus from patients admitted with diarrhea
(1992)
We studied the transmission of rotavirus (RV) in 950 patients under 2 years of age hospitalized for diarrhea in Santiago, Chile. Stool samples were collected every other day from all patients during their entire hospital ...
Prevalence of astrovirus infection among Chilean children with acute gastroenteritis
(1998)
The frequency of astrovirus infection in 456 Chilean children with diarrhea was determined by enzyme-linked immunosorbent assay, reverse transcriptase PCR, and cell culture. Astrovirus was detected in 16.5% of rotavirus-negative ...
Reactivity patterns and infection status of serum samples with indeterminate Western immunoblot tests for antibody to human immunodeficiency virus type 1
(1992)
Serum samples with indeterminate Western blot (WB) tests from 61 individuals whose sera were positive by enzyme-linked immunosorbent assay (ELISA) were studied in order to characterize their putative reactions with the ...
Diagnostic microbiologic methods in the GEMS-1 case/control study
(2012)
To understand the etiology of moderate-to-severe diarrhea among children in high mortality areas of sub-Saharan Africa and South Asia, we performed a comprehensive case/control study of children aged <5 years at 7 sites. ...
