Molecular Characterization of Obtained from Blood Cultures of Paediatric Patients Treated in a Tertiary Care Hospital in Mexico.

Purpose: is one of the main causative agents of hospital-acquired (HA) infections. In Mexico, information about the characteristics of clinical isolates is limited. Our aim was to characterize strains obtained from blood cultures of paediatric patients treated in a tertiary care hospital.

Real-Time Polymerase Chain Reaction-Based Detection of Bordetella pertussis in Mexican Infants and Their Contacts: A 3-Year Multicenter Study.

Objectives: To evaluate the usefulness of real-time polymerase chain reaction (RT-PCR) as a diagnostic method for the detection of Bordetella pertussis in hospitalized patients aged <1 year with a clinical diagnosis of whooping cough, as well as to identify the role of household contacts as a source of infection.

Study Design: This was a prospective, multicenter study of infants aged <1 year who were hospitalized with symptoms suggestive of whooping cough. Nasopharyngeal samples were obtained for culture and RT-PCR testing.

First Report of Group CTX-M-9 Extended Spectrum Beta-Lactamases in Escherichia coli Isolates from Pediatric Patients in Mexico.

The aim of this study was to identify the presence of group CTX-M-9 extended spectrum beta-lactamases (ESBL) in clinical Escherichia coli isolates from pediatric patients. A total of 404 non-repeated positive ESBL E. coli isolates were collected from documented clinical infections in pediatric patients over a 2-year period.

Pertussis in Latin America: epidemiology and control strategies.

Pertussis is a serious respiratory disease in infants that can also affect children and adults. Vaccination against pertussis was introduced in the 1950s and in the 1990s a resurgence of pertussis was observed worldwide. The aim of this work is to summarize the recent data concerning pertussis disease in different countries of Latin America.

Surveillance of healthcare associated infections in pediatric cancer patients between 2004 and 2009 in a public pediatric hospital in Mexico city, Mexico.

Pediatric oncology and hematology patients are at increased risk of developing healthcare associated infections (HAIs). We conducted a prospective surveillance study on children with cancer admitted to the pediatric hematology and oncology units at a public pediatric hospital in Mexico from January 2004 to December 2009. The incidence of HAIs and groups at greatest risk for HAIs were analyzed.
