Serendipia en el laboratorio de educación secundaria. La antibiosis

Molecules with antimicrobial activity, especially antibiotics, are studied in Compulsory Secondary Education. In this practical activity we show an act of serendipity, through the observation of antibiotic activity by bacteria on fungi in a sampling of heterotrophic microorganism colonies, as well as its impact and discussion on the teaching of science.Las moléculas con actividad antimicrobiana, en especial los antibióticos, son objeto de estudio en la Educación Secundaria Obligatoria. En esta actividad práctica se pone de manifiesto un hecho de serendipia, en cuanto a la observación de la actividad antibiótica por parte de bacterias sobre hongos en un muestreo de colonias de microorganismos heterótrofos, así como su repercusión y discusión en la enseñanza de las ciencias.Palabras clave: Serendipia; Antimicrobiano; Antibiosis; Antibiótico; Fleming; Laboratorio de Educación Secundaria.Serendipity in compulsory secondary education laboratory.
