Background. Since 1993 the Pan American Health Organization has coordinated a surveillance network with National Reference Laboratories of Argentina, Brazil, Chile, Colombia, Mexico and Uruguay aimed at monitoring capsular types antimicrobial susceptibility Streptococcus pneumoniae causing invasive disease in children <6 years age. Methods. The system included 6 age younger caused by S. pneumoniae. identification, typing to penicillin isolates were conducted using common protocol, based on...
Background: For the last 14 years Pan American Health Organization has been promoting surveillance of invasive pneumococcal disease in Latin children for better understanding tendencies regarding capsular types circulation each country and susceptibility to antimicrobials. Methods: Laboratory-based data from 10 countries collected 2000 2005 were analyzed, including serotype distribution beta-lactam antibiotics. Results: Although 61 different identified during 6-year surveillance, 13...
Background: Surveillance of antimicrobial resistance (AMR) requires an international approach with national and local strategies. Our aim was to summarize a retrospective 10-year report antibiotic gram-positive gram-negative bacteria in Mexico. Methods: A total 46 centers from 22 states Mexico participated. Databases AMR January 2009 December 2018 were included for most species. The period divided into five 2-year periods. Results: For Staphylococcus aureus, decrease all specimens observed...
Introduction of pneumococcal conjugate vaccines (PCV) targeted against a limited number serotypes substantially decreased invasive (IPD) and non-invasive diseases (NIPD) but it was accompanied by non-vaccine type replacement disease. After 9 years introduction PCV in Mexico, we analyze the evidence indirect effects on IPD NIPD serotype distribution among groups not to receive vaccine.From January 2000 December 2014, strains isolated from cases patients ≥5 age participant hospitals SIREVA II...
ObjectiveThe aim of this study was to determine the distribution serotypes and antimicrobial susceptibilities Streptococcus pneumoniae clinical isolates causing invasive non-invasive disease in children aged ≤60 days hospitals Mexico.MethodsA 15-year retrospective conducted for period 2000 2014. Pneumococcal were serotyped by Quellung reaction, susceptibility testing performed with broth microdilution method.ResultsA total 126 pneumococcal collected. Pneumonia most frequent diagnosis...
As part of the Sistema Regional de Vacunas (SIREVA) initiative, we conducted a surveillance study to determine relative prevalence capsular types Streptococcus pneumoniae and antimicrobial susceptibility invasive isolates in children less than 5 years old. We collected 220 found 33 90 known types, with type 23F as most common followed by 6A + B, 14, 19F, 19A. High penicillin resistance was 49 strains (22.2%), 31 belonging 23F. Twenty-nine (13.1%) were resistant erythromycin, 95 (43.1%)...
During a surveillance study to determine the relative prevalence of capsular types Streptococcus pneumoniae and antimicrobial susceptibility invasive isolates in children <5 years old Mexico City, 220 were collected. The serotype 23F was most common found, followed by 6A + B, 14, 19F, 19A. Diminished penicillin detected 106 (48.2%), high resistance found 49 strains (22.2%), 31 belonging type 23F. Resistance also observed erythromycin (13.1%), chloramphenicol (43.1%), cefotaxime (10.9%). No...
The aim of this study was to assess the risk factors and clinical microbiological characteristics community-acquired pneumonia (CAP) in adult patients Mexico. Streptococcus pneumoniae classified as causative agent CAP with invasive S. isolates presented three tertiary teaching hospitals during 15-year period were selected. Serotyping susceptibility testing performed for all included isolates. Clinical demographic data recorded. A total 96 infected (71 CAP, 25 disease) included. group...
Objetivo. Conocer la prevalencia de S. pneumoniae serotipo 19A (Spn19A) antes y después introducción vacuna conjugada heptavalente (PCV7) en México. Material métodos. Estudio descriptivo realizado con información sobre vigilancia enfermedades causadas por neumococos, generada red Sireva. Se realizó un análisis regresión lineal proporción cepas Spn19A año, dos periodos. Los datos se analizaron el paquete estadístico SPSS v.18. Resultados. Durante periodo 2000-2012 recuperaron 1 825 causantes...
Antimicrobial resistance is a global concern. Analysis of sterile fluids essential because microorganisms are defined as significant in most cases. Blood, cerebrospinal, and pleural frequently received the microbiology lab they associated with considerable rates morbi-mortality. Knowledge epidemiology these samples needed to choose proper empirical treatments due importance reducing selection pressure.We used retrospective laboratory data blood, CSF, fluid collected from patients Mexico...
Streptococcus pneumoniae expressing serotype 3 has a high virulence and case fatality ratio. Most studies of pneumococci have focused on single lineage, the widespread sequence type 180 (ST180).
Non-typeable Haemophilus influenzae (NTHi) is a common opportunistic bacterial pathogen that primarily infects the respiratory mucosa. This study was conducted to assess clinical and microbiological data related disease severity in patients with lower tract infections caused by NTHi tertiary care hospital Mexico. isolates were subjected serotyping, antimicrobial susceptibility evaluationand analyses of β-lactamase production, genetic relatednessand biofilm formation. Clinical demographic...
To describe the clinical and molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA) strains that were collected in Hospital Regional de Alta Especialidad Veracruz (HRV).A total 107 MRSA from individual patients examined. The between September 2009 2010. demographic analyzed; typing by pulsed-field gel electrophoresis (PFGE), staphylococcal chromosomal cassette mec (SCCmec) multilocus sequence used to characterize isolates.Two PFGE patterns (NY/J IB) identified with 4...

To describe the distribution of pneumococcal serotypes causing infectious diseases in patients with hematological malignancies and solid tumors their antimicrobial susceptibility before after introduction conjugate vaccine (PCV7) Mexico.Consecutive isolates from hospitalized SIREVA-network were serotyped using Quellung reaction was performed broth microdilution method.A total 175 recovered, 105 70 tumors. Serotypes 19A (22.7%), 19F (20.4%), 35B (17.7%) most frequent first group 3 (27.2%)...
Introducción: En México, cuando se inició la aplicación de vacuna PCV13 (neumocócica conjugada), cubría el 70.6% los serotipos causantes enfermedad invasiva por neumococo en menores 5 años.Después varios años, casos causada incluidos han disminuido; sin embargo, ha producido un reemplazo no vacuna.Caso clínico: Se presentan tres pacientes pediátricos que desarrollaron PCV13: uno con meningitis y bacteriemia (serotipo 15C) dos neumonía, ellos complicado derrame 35B).Los fueron atendidos...
