Currently there is a need for new antibiotics with an alternative mode of action and new chemical structures. Bacterial pathogens are gradually becoming more resistant to conventional antibiotics, generating an emergence of infectious diseases and they are becoming a great problem in the field of public health. In this study, seven different isolated bacteria were obtained from offshore seawater and sediment of the Gulf of Mexico from Campeche, Mexico. They were substance producers which inhibit growth of human pathogens like Staphylococcus aureus and Pseudomonas aeruginosa and one of them was a polymer producer on peptone and glucose culture. They were characterized phenotipically by means of morphological techniques and physiologically by conventional tests. Four of them were Gram-positive bacteria and the Scanning Electron Microscope analysis revealed their size between 0.6 - 1.5 µm....

El propósito de la investigación titulada “Aprendizaje cooperativo: ventajas y beneficios en el desarrollo de las habilidades sociales de los estudiantes de Educación Básica Regular”, tuvo como objetivo general explicar el aprendizaje cooperativo como estrategia en el desarrollo de las habilidades sociales de los estudiantes de Educación Básica Regular. Esta investigación de tipo cualitativa básica utilizó el diseño hermenéutico interpretativo para construir una teoría a partir del análisis de la información obtenida de fuentes bibliográficas, una directora y cinco docentes del nivel secundaría de Condorcerro, distrito de Quiches (Ancash) quienes respondieron a una entrevista semiestructurada. Los resultados demuestran que, aprendizaje cooperativo permite a los estudiantes el aprendizaje en forma grupal mediante la interacción motora e interdependencia positiva poten...
