The present work investigated the in vitro antimicrobial activities of ethanolic, methonolic and hydroalcoholic extracts corresponding to four plants of north easter of Peru; Cassia reticulata (whole plant), Ilex guayusa Loes (leaves), Piper lineatum (leaves), y Terminalia catappa (leaves). The plants were collected in the department of Cajamarca, except Terminalia catappa (Amazonas). The antimicrobial activity was determinated by the method of agar diffusion. The used microorganisms were the bacteria Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, Bacillus subtilis and Escherichia coli; and the fungals Candida albicans, Aspergillus niger and Microsporum canis. Of twelve investigated extracts, eight (67%) presented significant antimicrobial activity against Staphylococcus aureus and Staphylococcus epidermidis and one (8%) against Escherichia coli. Of twelve inv...

Tuberculosis is a public health problem in the world and Peru, aggravated by multidrug (MDR-TB) and extensively resistant (XDR-TB) forms. The objetives were to describe the resistance to tuberculosis drugs and risk factors to acquire MDR-TB in a marginal urban hospital of Lima, since 2006 to 2008. It is a reported cases studyand was undertaken in Huaycán Hospital. The data collected were acquired from the routine reports of the National Control Program and clinical history. A total of 61 cases of MDR-TB, one of XDR-TB and 7 cases of mono resistant tuberculosis were evaluated; 38 were men (55%) and 31 women (45%). The more affected age group were 15 to 34 years with 55 cases (79,6%). The more frecuent risk factors founded to acquire MDR-TB were: suspicion of failure (FS1, 34 cases, 49%) and failure of treatment one scheme (F1, 14 cases, 20%), and to have had contact with MDR-TB patients ...

The present research was aimed to determine qualitatively the chemical constituents and antibacterial, antifungal and antioxidant activity of essential oil from leaves of Tagetes elliptica Smith “chincho”, native of the province of Huaraz, Ancash region, which was obtained by the method of distillation with water vapor. Later physicochemical constants were determined, and then made the determination of chemical composition by Gas Chromatography / Mass Spectrometry (GC/MS). By the methods of agar diffusion and agar dilution were determined antimicrobial activities and minimum inhibitory concentration (MIC), respectively, against the following microorganisms: S. aureus ATCC 25933, S. epidermidis (clinical isolate), B. subtilis (environmental strain), E. coli (clinical isolate), P. aeruginosa ATCC 27853, Klebsiella (clinical isolate) and C. albicans ATCC 10231. In tests, the essential o...
