Objetivo: identificar Staphylococcus aureus, y luego evaluar el comportamiento de éstas cepas frente a los antibióticos recomendados en clínica, siguiendo las normas técnicas del Instituto Nacional de Salud.  Métodos: El presente estudio observacional, transversal y descriptivo, es parte del programa de formación en el curso de Microbiología, que se imparte a los alumnos de Medicina. Participaron 234 alumnos, correspondientes a tres ciclos académicos, a los que se les tomó una muestra de hisopado de mucosa nasal, con el objetivo de identificar Staphylococcus aureus, y luego evaluar el comportamiento de éstas cepas frente a los antibióticos recomendados en clínica, siguiendo las normas técnicas del Instituto Nacional de Salud. Resultados: La prevalencia de portadores sanos de S. aureus es de 12,8%. El 80% (24/30) de las cepas fueron productoras de beta lactamasa (penicil...

Objective: Compare the values of the blood biomakers: uric acid, creatinine, glucose, cholesterol and triglycerides, in two groups of university professors apparently healthy. Methods: The first group, formed by 58 professors aged 60 to 64, and the second formed by 35 professors aged 75 to 81, in order to evaluate if there is a significant statistic difference in both groups. Results: The values of uric acid in group I were between 2,50 mg/dL. and 8,20 mg/dL; in groups II were between 2,50 mg/dL and 8,63 mg/dL, showing a significant difference (p=0.035). The values of creatinine in group I were between 0,64 mg/dL and 1,56 mg/dL; and in group II were between 0,80 mg/dL and 1,61 mg/dL., showing a significant difference (p=0.004). The values of glucose in group I were between 63 mg/dL and 188 mg/dL; and in group II were between 60 mg/dL y 297 mg/dL, not showing significant differe...

Viruses that parasitize bacteria, called bacteriophages or phages, are returning to scientific news, evidenced by the creation of the Howard Hughs Medical Institute in the United States (USA), or the CRU-MEDI Institute in the United Kingdom; This change of interest is due to the possibility of using them in antibacterial therapy, against multiresistant bacteria. The knowledge of these viruses begins with the studies of Frederick Twort in the year 1915, demonstrating that "there are viruses that infect bacteria and kill them." But it was Felix d'Herelle, who successfully developed therapeutic protocols for digestive infections in animals and humans. Bacteriophages have been the basic laboratory tool for the development of science in virology and molecular biology.

The objective was to know the hand hygiene habits of medical students; as well as the bacterial population resident in the palm of the hands. An observational, descriptive cross-sectional study was carried out. Likewise, a hand hygiene behavior survey was carried out on 100 students, and a microbiological culture of the palmar surface was carried out on 33 other students. Regarding hygiene habits, 74% showed an appropriate attitude. The hygiene attitude was appropriate in 41.3% and 46% in relation to the prevention of contagion. The following pathogenic microorganisms were isolated: S.aureus with 20 cases (60.6%), P. aeruginosa, Enterobacter and S.viridans, one in each case. Therefore, workshops or dissemination campaigns should be organized to raise awareness and modulate hand hygiene habits in students.

El presente trabajo estudia el test del Uroscreen como prueba química para el diagnóstico rápido de las infecciones urinarias. La prueba se basa en que la actividad metabólica de las bacterias es capaz de reducir al cloruro de 2, 3, 5 trifenil tetrazolium (T.T.C.) a un precipitado insoluble y coloreado, visible a simple vista, que se presenta cuando el número de bacterias en el espécimen es superior a 100,000 por c.c., cifra compatible con infección urinaria.

Fourteen patients with unusual type of Salmonellosis (extra.intestinal), are studied, nine of these patients were under two years of age. The date was obtained from 7,500 cultures done on purulent secretions and spinal fluid during a period of seven years (1965-1971) and collected at the Microbiology Service of the Children Hospital of Lima.
