Antibióticos são substâncias,
desenvolvidas a partir de fungos, bactérias ou elementos sintéticos (produzidos
em laboratórios farmacêuticos). A finalidade do antibiótico é combater
microrganismos, causadores de infecções no organismo.







O uso indiscriminado,
principalmente sem orientação e acompanhamento médico, pode ser prejudicial à
saúde. Além disso, favorece o desenvolvimento de microrganismos resistentes a
determinados antibióticos.







O pesquisador inglês Alexander
Fleming foi quem desenvolveu o primeiro antibiótico, a penicilina. Ao fazer
pesquisas com uma colônia de bactérias, por acaso, estas entraram em contato
com uma espécie de fungo. O pesquisador percebeu que as bactérias não se
desenvolviam na presença daqueles fungos.
