Germs Theory of Disease

Pensando em colocar um pouco de conhecimento nesse blog, decidi publicar aqui um dos meus trabalhos para a classe de Writing. Este e' sobre sobre a teoria de doencas causadas por germes, escolhi esse tema quando nossa professora Kirby nos pediu para escrever sobre uma invencao.

Thinking in put some knowledge in this blog, I decided to publish here one of my Writing Class works. This one is about the Germs Theory of Disease, theme that I chose when our teacher Kirby asked us to write about an invention.

Modestia a parte, achei miha conclusao bastante poetica. Muito boa. Beijos pra todos.

Without modesty, I though my conclusion is pretty poetic. Very good. Kisses to everybody.

Teoria das Doencas Bacterianas

Antes da Teoria das Doencas Bacterianas, nao era de conhecimento geal o quao mortais bacterias poderiam ser. Era comum ver um doutor atender varios pacientes de doencas diferentes sem trocar luvas e vestimenta. Assim como nenhum instrumento medico como agulhas, serras, ou termometros nao eram muito bem desinfetados antes de serem usados em outros pacientes. Estes sao exemplos de habitos mudados pela Teoria de Doencas Bacterianas. Muitos estudiosos estavam envolvidos no desenvolvimento dessa teoria. Antigamente, Geracao Espontanea era considerada valida, significando que as pessoas acreditavam que vida poderia surgir de materias nao-vivos, e microorganismos nao eram conhecidos. Equivalentemente, ninguem imaginava que vida microscopica (bacteria) poderia transmitir doencas. Entao, Ignaz Semmelweis analisou em 1847 que mais mulheres morriam em dar a luz no hospital do que em casa. O motivo era que doutores de um hospital lidam com todo tipo de doencas num mesmo dia, com as mesmas roupas. Sem assepsia, medicos contaminavam as gravidas com as mais diversas doencas. Joseph Lister, entorno de 1860, foi aquele que fez com medicos passassem a usar esterilization em seus trabalhos, desta forma pode prevenir contaminacao de acontecer, mergulhando instumentos medicos em agua fervente. E’ gracas a Louis Pasteur (entorno de 1862) que o habito de beber agua e leite antes de ferver caiu em desuso. Contemporaneamente, seu legado por ser visto no processo de pasteurizacao, vacinacao e outras contribuicoes. Em conclucao, todas as mudancas de habitos causada pela Teoria de Doencas Bacterianas savaram muitas vidas. Prevenir doencas e’ o melhor tratamento, e conhecimento e’ o melhor remedio.

The Germ Theory of Disease

Before the Germ Theory of Disease, people did not know how deathful bacteria could be. It was common to see a doctor attending patients from different diseases without wearing new gloves or clean clothes. Likewise, any medical instruments as needles, saws, or thermometers were not very well disinfected before been used to other patient. These are examples of changing habits because of Germ Theory of Disease. Many studious were involved in the development of this theory. Formerly, Spontaneously Generation was validity as right, meaning that people believed that life could birth from none-living materials, and microorganisms were not known. Similarly, nobody imagined that small life (bacteria) could transmit diseases. Therefore, Ignaz Semmelweis analyzed in 1847 that more women died giving birth in hospitals than at home. The reason was that doctors in a hospital deal with all kind of diseases at the same day, in the same clothes. Without antiseptic doctors contaminated the pregnant woman. Joseph Lister, around 1860, was the one who made doctors start using sterilization in their work, this way could prevent sepsis from happening by submerging medical tools in boiling water. It is thanks to Louis Pasteur (around 1862) that the habit of drink water and milk before boiling began to be in disuse. Contemporary, his legacy is seen in the pasteurization process, vaccination, and other contributions. In summary, all modification of habit caused by the Germ Theory of Disease saved a lot of lives. Preventing a disease is the better treatment, and knowledge is the better medicine.
