Novel recombinant norovirus causing outbreaks of gastroenteritis in Santiago, Chile (2006)
Vidal, Roberto, Roessler, Patricia, Solari, Verónica, Vollaire, Jimena, Jiang, Xi, Matson, David O., ...
Capsid and polymerase (RdRp) genes of 13 norovirus outbreak strains from Chile were compared. The genes sequences were discordant for five strains, and recombination was confirmed for two of them by...
Vidal, Maricel, Kruger, Eileen, Durán, Claudia, Lagos, Rosanna, Levine, Myron, Prado, Valeria, ...
We designed a multiplex PCR for the detection of all categories of diarrheagenic Escherichia coli. This method proved to be specific and rapid in detecting virulence genes from Shiga toxin-producing...
Levine, Myron, Ferreccio, Catterine, Prado, Valeria
In October, 1986, a randomized, controlled field trial was initiated in Area Sur Oriente and Area Norte, Santiago, Chile, to compare the relative and absolute efficacy of three doses of Ty21a vaccine...

Levine, Myron M., Ferreccio, Catterine, Prado, Valeria
In a randomized, double-blind, controlled field trial in Santiago, Chile, 81,621 school-children, 5-19 years of age, received three doses, within one week, of attenuated Salmonella typhi oral vaccine...
Levine, Myron M., Ferreccio, Catterine, Prado, Valeria, Cayazzo, Marisol, Abrego, Paulina, Martinez, Juan, ...
The incidence of diarrhea due to six categories of diarrheogenic Eschenchia coli was determined in two pediatric cohorts in a low socioeconomic level community in Santiago, Chile, with access to...
Ferreccio, Catterine, Prado, Valeria, Ojeda, Alicia, Cayyazo, Marisol, Abrego, Paulina, Guers, Linda, ...
To prepare a field site for evaluating preventive interventions against endemic shigellosis, the authors followed prospectively a cohort of 360 children (90 each of children aged 0–11,12–23,...
Trimethoprim resistance in enterobacteria isolated in Chile (1989)
Urbina, Rosalba, Prado, Valeria, Canelo, Eliana
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...
Rios, Maritza, Prado, Valeria, Trucksis, Michele, Arellano, Carolina, Borie, Consuelo, Alexandre, Marcela, ...
To determine clonal relationship among Chilean enterohemorrhagic Escherichia coli (EHEC) strains from different sources (clinical infections, animal reservoirs, and food), 54 EHEC isolates (44 of E....
Gherardi, Giovanni, Inostrozo, Jaime S., O'ryan, Miguel, Prado, Valeria, Prieto, Susana, Arellano, Carolina, ...
To assess pneumococcal strain variability among young asymptomatic carriers in Chile, we used serotyping, antibiotic susceptibility testing, and genotyping to analyze 68 multidrug-resistant...
Prevalence of Astrovirus Infection among Chilean Children with Acute Gastroenteritis
Gaggero, Aldo, O’Ryan, Miguel, Noel, Jacqueline S., Glass, Roger I., Monroe, Stephan S., Mamani, Nora, ...
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...
Inostroza, Jaime, Trucco, Olivia, Prado, Valeria, Vinet, Ana Maria, Retamal, Gloria, Ossa, Gonzalo, ...
We compared the incidence of nasopharyngeal colonization by Streptococcus pneumoniae, the serotypes causing mucosal and invasive diseases, and the antibiotic resistance of these strains in patients...
Multiplex PCR for Diagnosis of Enteric Infections Associated with Diarrheagenic Escherichia coli
Vidal, Roberto, Vidal, Maricel, Lagos, Rossana, Levine, Myron, Prado, Valeria
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...
