Summary: Studies confirm the presence of potentially pathogenic microorganisms in leaf snuff. These could be reached by drag through the smoke to the airways and trigger a number of lung diseases. Therefore, the cigarettes could be considered a direct source of microorganisms that come to colonize the respiratory tract of active smokers, especially in immunosuppressed. The objective was to determine if bacteria and fungi in leaf snuff are drawn by aspirating smoke cigarettes. transversal and prospective study of non-experimental design. It was held in the Augustinian where 10 cigarette packets of two different brands (two groups of 5 packs) using a mechanical suction consisting of a flask Kitazato, graduated pipette, syringe 60ml, ducts and caps processed jebe. 10 packs analyzed brand A (5 packs), bacterial growth was obtained in 80% and the mark B (5 packs), 60% both corresponding to Ba...

Objective: To evaluate the diagnostic performance of blood agar with filter (BSA) in comparison with Karmali agar (AK) for the diagnosis of Campylobacter spp in stool culture. Material and methods: A cross-sectional prospective experimental research was carried out at the Hospital Nacional Docente Madre-Niño "San Bartolomé", where stool samples with functional stool examination reactive for inflammation were evaluated. The samples were seeded in ASF and AK and incubated up to 72 hours in microaerophilia. Species differentiation was performed with hippurate hydrolysis. Results: A total of 287 positive samples were collected. The isolation of Campylobacter in ASF and AK was 78.3% and 21.7%, respectively. Sensitivity was 90.9% for ASF. Mean growth time was 32.7 ± 11 hours (p<0.59) and contamination of culture media from positive patients was 61.7% for AK. 74.8% of non-jejuni Campyloba...

Introduction. Given the appearance of reports of the presence of the mcr-1 gene and its possible dissemination by plasmids in the countries of the region and given that this gene confers resistance to colistin, the drug that is the last line of treatment against multiresistant bacteria, it is important to know its presence in our country in microorganisms that express it. Methods. Descriptive and cross-sectional study was carried out. Microorganisms isolated from urine culture of outpatients from a private health center in Lima, Peru, were included in august 2017. Out of 326 positive urine cultures, 10 isolates were selected between strains of Escherichia coli and Klebsiella pneumoniae that had a minimum inhibitory concentration ≥4μg/mL (interpreted as resistant for colistín) by the automated system Microscan Walkaway 96 plus. The following methods were used: colistin agar spot, pred...
