Among the microbiological agents that can cause infections in diabetic feet are those from the skin and intestinal flora. This study aimed to "Determine which bacterial agents are most predominant in diabetic feet isolated in the central laboratory of the María Auxiliadora Departmental Hospital in Lima, Peru, during the 2019 period." The methodology used was an observational, cross-sectional, and descriptive study. A total of 181 positive culture data with their respective susceptibility profiles were analyzed, concluding that the predominant bacterial agents were Gram-negative bacteria (63%), with the most frequent being Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, and Morganella morganii. The most sensitive drugs were Carbapenems, Amikacin, Vancomycin, and Teicoplanin, while the most resistant were Ampicillin, Cefuroxime, Penicillin, and Clindamycin.

Enterobacteria most commonly found on smart phone (TI) of the staff of a clinic in San Juan de Miraflores Peru period september, 2022
(Universidad Privada Norbert Wiener, 2023-11-26) Castro Ccoscco, Maria Luisa; Cabello Vílchez, Alfonso Martin
Smartphones are devices with continuous handling, showing a high percentage of contamination on the surfaces of these devices, reflecting a public health problem. They are capable of adhering to and surviving on inert surfaces, transferring pathogens to patients via hands. The objective of the study was to describe the species of Enterobacteria most commonly found on smartphones (SS) of the staff of a clinic. It was observational, descriptive, cross-sectional, and prospective. The representative samples were 36 touchscreen smartphones along with informed consent and selection criteria. For the bacteriological analysis, the Stuart transport medium was used, which preserves the sample until reaching the laboratory. Swabs were taken from the edges and back of the smartphones, followed by microbiological culture to describe bacterial growth on culture media and identify the species using biochemical tests, concluding with the antibiogram. Results were presented in tables using Microsoft Excel. Enterobacteria were found, with Escherichia coli and Klebsiella pneumoniae being the predominant species.

Performance of the Geneexpert MTB/RIF test in the diagnosis of Mycobacterium tuberculosis in respiratory and non-respiratory samples of the Hospital Nacional Hipólito Unanue Lima-Perú 2020.
(Universidad Privada Norbert Wiener, 2022-07-07) Taipe Tuñoque, Geraldine María; Cabello Vílchez, Alfonso Martin
This research used a descriptive, basic methodology with a qualitative approach. The main objective was to determine the performance of the Genexpert MTB/RIF test in diagnosing Mycobacterium tuberculosis in respiratory and non-respiratory samples, as tuberculosis remains a public health issue. Given that the Hipólito Unanue National Hospital is a reference hospital for this pathology, located in areas of high population density requiring rapid and timely diagnosis, the Genexpert MTB/RIF test stands out due to its qualities. The performance of the Genexpert MTB/RIF test was evaluated by comparing it to solid culture as the Gold Standard, assessing diagnostic parameters. It was shown that the Genexpert MTB/RIF test had good performance compared to the Gold Standard in diagnosing Mycobacterium tuberculosis in both respiratory and non-respiratory samples from the Hipólito Unanue National Hospital.

Performance of the Genotype MTBDRplus test for the diagnosis of multidrug resistance in patients affected by tuberculosis at the Piedra Liza Maternal and Child Center from January-June 2020
(Universidad Privada Norbert Wiener, 2023-04-16) Morón Porras, Oscar Arturo; Cabello Vílchez, Alfonso Martin
Tuberculosis caused by Mycobacterium tuberculosis can lead to resistance to first-line drugs due to various factors. Among diagnostic methods, the most common are bacilloscopy and conventional culture. Recently, methods like the GENOTYPE MTBDRplus test have been used to detect multidrug resistance. Objective: To assess the performance of the GENOTYPE MTBDRplus test for diagnosing multidrug resistance in tuberculosis patients at the Piedra Liza Maternal-Child Center during January to June 2020. Methodology: The research method is hypothetical-deductive, qualitative, non-experimental, observational, and cross-sectional. A total of 155 patients were considered for the study. Statistical descriptive tools were used. Results: 55.5% of patients were male, 44.5% were female. The study showed resistance to Isoniazid in 14.2% and to Rifampicin in 4.5%. The GENOTYPE method detected more resistance to Isoniazid. Both methods showed similar sensitivity to Isoniazid. Conclusion: The GENOTYPE test is highly reliable and provides faster results for diagnosing multidrug-resistant tuberculosis, leading to timely treatment.
