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 Cryptococcosis due to Cryptococcus gattii is endemic in various parts of the world, affecting mostly immunocompetent patients. A national surveillance study cryptococcosis, including demographical, clinical and microbiological data, has been ongoing since 1997 Colombia, provide insights into epidemiology this mycosis. Methodology/Principal Findings From 1,209 surveys analyzed between 1997–2011, 45 cases caused by C. were reported (prevalence 3.7%; annual incidence 0.07...
Introduction. A national survey on cryptococcosis has been conducted in Colombia since 1997. The data recorded over a 9-year period, 1997 to 2005, was summarized.Materials and methods. format provided by the European Confederation of Medical Mycology adapted with correspondent permission.Results. Over 9 year 931 surveys were received from 76 centers. associated disease syndromes as follows: 891 (95.7%) neurocryptococosis cases, 27 (2.9%) pulmonary disease, 5 (0.5%) cutaneous lesions, 2...
Introduction. Histoplasmosis, a fungal disorder characterized by wide spectrum of manifestations that range from subclinical infections to disseminated processes, affects both immunocompetent and immunosuppressed individuals. Histoplasmosis is not reportable disease in Colombia consequently, survey was designed collect histoplasmosis cases diagnosed the country.Objective. The aim this work analyze data collected 1992 2008.Materials methods. included demographic data, risk factors, clinical...
OBJETIVOS: Analizar las características fenotípicas y la susceptibilidad a antibióticos de cepas circulantes Streptococcus pneumoniae, Haemophilus influenzae Neisseria meningitidis en América Latina el Caribe entre 2000 2005. Se evaluó cobertura potencial vacunas conjugadas. MÉTODOS: estudió por métodos convencionales distribución los serotipos o serogrupos 17 303 S. 2 782 H. 6 955 N. aisladas casos neumonía, meningitis, sepsis, bacteriemias otros procesos invasivos. estudiadas.

The passive and voluntary surveillance of cryptococcosis in Colombia since 1997 has seen an increasing participating rate, revealing its importance to both immunosuppressed immunocompetent people. present work details the national data gathered 1997-2016, through a retrospective analysis information collected survey. From total 1974 cases reported, overall incidence 0.23 per 100,000 people was found. This rose 1.1 1000 Acquired Immunodeficiency Syndrome (AIDS) population. Cryptococcosis most...
Introduction. A survey on cryptococcosis is being conducted regularly in Colombia since 1997. Wepresent hereby the results corresponding to patients diagnosed from 2006 2010.Objective. To analyze data obtained during this period.Materials and methods. Retrospective analysis of surveys.Results. total 526 surveys originating 72% Colombian political divisions were receivedduring 5-year period. Most (76.6%) males 74.9% 21-50 years old. Themost prevalent risk factor was HIV infection (83.5%) with...
A previous study carried out in a tertiary care hospital Colombia demonstrated the usefulness of Cryptococcus capsular antigen detection by latex (CrAg Latex) early diagnosis cryptococcosis HIV-infected patients with low CD4 + levels. The aim this was to establish performance new rapid lateral flow assay LFA) preserved sera those collected between 2001 and 2006. total 421 from 297 confirmed HIV were tested CrAg LFA results compared obtained Latex. All provided informed consent for specimen...
: The objective of this study was to ascertain the antimicrobial susceptibility Neisseria gonorrhoeae isolates from 6 South American and 13 Caribbean countries participating in Gonococcal Antimicrobial Surveillance Program (GASP) 1990 1999.: A GASP network laboratories launched Americas during 1990s. Standardized methods interpretative criteria were established for isolation N. gonorrhoeae, strain identification, determination, quality control susceptibility.: Two (Argentina Uruguay)...
En 1998, el Ministerio de Salud Colombia inició la vacunación contra Haemophilus influenzae b (Hib) en menores 1 año. 1999 se evaluó impacto esta intervención incidencia meningitis bacteriana aguda (MBA) utilizando los datos del sistema vigilancia por laboratorio que coordina desde 1994 Grupo Microbiología Instituto Nacional Salud. análisis comparó número anual casos Hib niños año diagnosticaron vigilancia, antes introducirse vacuna, con registrados durante primer después iniciada...
The impact of invasive pneumococcal disease is increased by the emergence antibiotic resistance. We report regional and temporal variations in resistance for 4,105 Streptococcus pneumoniae isolates collected from Latin American children <5 years, between 1993 1999. Reduced susceptibility to penicillin was detected 1,182 (28.8%); 36% these were resistant (> or = 2 microg/ml), including 12.6% with MIC > 4 microg/ml, occurring primarily serotypes 14 23F. third-generation cephalosporins 12.1%...
Streptococcus pneumoniae is an important cause of morbidity and mortality in children adults the world.Analysis data from laboratory surveillance S. pneumoniae, invasive isolates recovered 1994 to 2004.Database sent Microbiology Group through national network acute bacterial meningitis respiratory infections, 2004. The had epidemiological data, serotyping, antimicrobial susceptibility patterns some them molecular typing.The 2,022 120 hospitals different regions country were analyzed. mainly...
To examine the development of resistance to erythromycin, chloramphenicol, trimethoprim-sulfamethoxazole (TMP-SMZ), and vancomycin invasive isolates Streptococcus pneumoniae obtained from children in 10 Latin American/Caribbean countries during six years surveillance.Analysis 8 993 S. recovered 2000-2005 with infections, who were less than 6 age, Argentina, Brazil, Chile, Colombia, Cuba, Dominican Republic, Mexico, Paraguay, Uruguay, or Venezuela. Antibiotic susceptibility was determined...
In 1993 the Pan American Health Organization initiated a laboratory-based surveillance system, called SIREVA project, to learn about Streptococcus pneumoniae invasive disease in Latin children. 1994, National Laboratories six countries were trained perform serotyping and antibiotic susceptibility testing using broth microdilution determine MIC for specified antibiotics. An international External Quality Assurance (EQA) program was developed monitor support ongoing laboratory performance. The...
La neumonía adquirida en la comunidad es una de las principales causas morbilidad y mortalidad infancia. Estudios realizados países desarrollo indican que los cuadros más graves se asocian a bacterianas, con predominio Streptococcus pneumoniae, seguido por Haemophilus influenzae tipo b. El manejo esas infecciones menores 2 años ve dificultado carencia vacunas apropiadas disminución susceptibilidad S. pneumoniae penicilina otros antibióticos. En 1993, iniciativa del Sistema Regional Vacunas...
Salmonella Typhi is the etiological agent of typhoid fever with 16 million annual cases estimated worldwide. In Colombia and Argentina it a notifiable disease but many have only clinical diagnosis. Molecular subtyping S. necessary to complement epidemiologic analysis fever.
