Objective: To study the presence in two hospitals of Lima of extended spectrum β-lactamases (BLEE) and to identify TEM and SHV types produced by Escherichia coli and Klebsiella pneumoniae strains. Material and Methods: The selection and confirmation of BLEE producing strains was done by antimicrobial susceptibility tests. The identification of bla TEM and bla SHV genes was achieved by polymerase chain reaction (PCR) and DNA sequencing. Results: One hundred and thirty seven Escherichia coli and 18 Klebsiella pneumoniae strains were isolated from hospitalized patients between July and September 2000. Most showed high resistance to third-generation cephalosporins and aztreonam;2,9% of all E.coli and 44,4% of all K.pneumoniae isolates were confirmed as BLEE producer strains. All BLEE producer strains were multidrug-resistant and most presented coresistance to trimethoprim/sulfamethoxazole, ...

Tuberculosis (TB) is a public health problem, worsed by multidrugs resistant forms (MDR-TB). The control of MDR-TB require a well definition of patient epidemiological situation before start treatment and clarify the rol of different risk factors associated to MDR-TB . The objectives were to determine the associated factors to MDR-TB in urban marginal health public centers from East Lima. This is an observational and analytical case-control study, age and gener matched, undertaken since 2006 to 2008. We defined as case all patients who were diagnosticated and treated to MDR-TB and as control all patients who were recuperated from tuberculosis with primary scheme. The data was acquired from the routine reports of the National Control Program. 252 patients were incorporated, 126 cases and 126 controls. 108 (85,7%) controls and 19 (15%) cases were new. 45 (36%) cases were failures to previo...

Tuberculosis is a public health problem, generated by poverty, with high prevalence and incidence. The objetives of this study were to determine the associated factors to tuberculosis in a marginal urban health center of Lima. This is an observational study of case report undertaken in Chaclacayo since January 1999 to December 2008. The data collected was acquired from the routine reports of the National Control Program. A total of 197 cases were evaluated; 108 were men (55%) and 89 were women (45%). Within these 197 subjects, 151 were new cases (76.6%) and 32 were individuals who had been previously diagnosed with tuberculosis (16.2%). The incidence decreased from 305 x 100 000 in 1999 to 119 x 100 000 inhabitants in 2008. The more affected age groups were 15-29 years with 103 cases (52.3%). 174 patients showed a high prevalence of pulmonary tuberculosis (88%); successful treatment were...
