Resumo: | Stained preparations are the most commonly microscopic exam used in microbiology, as they provide a better view of microorganisms. Bearing in mind that Gram and Wirtz-Conklin staining techniques are commonly used in the routine of microbiology laboratories and in practical classes, this project aimed to compare the standard staining technique on slide surfaces, with the technique by immersion, which in turn can avoid waste of dyes, environmental impact and reduce laboratory and teaching costs. Thus, bacterial smears (Escherichia coli; Staphylococcus aureus; Alicyclobacillus acidoterrestris and Bacillus subtilis) were made on glass slides, followed by flame fixation. After, the slides were submitted to staining using the surface technique and the immersion technique. Subsequently, the slides were viewed under a standard optical microscope and the resolution of the images and tinting characteristics were evaluated and recorded. The staining by immersion, both for Gram stain and Wirtz-Conklin, avoided the waste of the dyes used in the techniques, as well as, the saturation of the solutions after many slide passes. Thus, the immersion staining technique is favorable for use in classes or microbiology laboratories. The application of this technique has shown significant results for the reduction of waste and, consequently, the impacts on the environment and the economy of educational institutions. |

Teniendo en cuenta que las técnicas de tinción de Gram y Wirtz-Conklin se utilizan comúnmente en la rutina de los laboratorios de microbiología y en las clases de microscopía teñida, este proyecto tuvo como objetivo comparar la técnica de tinción estándar en superficies de portaobjetos, con la técnica de inmersión, que a su vez puede evitar el desperdicio de tintes, el impacto ambiental y reducir los costos de laboratorio y enseñanza. Por lo tanto, se hicieron frotis bacterianos (Escherichia coli; Staphylococcus aureus; Alicyclobacillus acidoterrestris y Bacillus subtilis) en portaobjetos, seguidos de fijación con llama. Después de este procedimiento, los portaobjetos se sometieron a tinción mediante la técnica de superficie y la técnica de inmersión. Posteriormente, los portaobjetos se visualizaron bajo un microscopio óptico estándar y se evaluó y registró la resolución de las imágenes y las características de tinción. La técnica de tinción por inmersión, tanto para la tinción de Gram como para Wirtz-Conklin, evitó el desperdicio de los colorantes utilizados en las técnicas, así como la saturación de las soluciones tras muchas pasadas de portaobjetos. Por tanto, la técnica de tinción por inmersión es favorable para su uso en clases o en laboratorios de microbiología. La aplicación de esta técnica ha mostrado resultados significativos para la reducción de residuos y, en consecuencia, los impactos sobre el medio ambiente y la economía de las instituciones educativas.As preparações coradas são os exames microscópicos mais comumente empregados em microbiologia, pois proporcionam uma melhor visualização dos microrganismos. Tendo em vista que as técnicas de coloração de Gram e Wirtz-Conklin são comumente utilizadas na rotina de laboratórios de microbiologia e nas aulas de microscopias coradas, este projeto teve como objetivo comparar a técnica padrão de coloração em superfície das lâminas, com a técnica por imersão, que por sua vez pode evitar o desperdício de corantes, impacto ambiental e diminuir custos laboratoriais e no ensino. Dessa forma, foram feitos esfregaços bacterianos (Escherichia coli; Staphylococcus aureus; Alicyclobacillus acidoterrestris e Bacillus subtilis) em lâmina, seguidos de fixação em chama. Após esse procedimento as lâminas foram submetidas à coloração pela técnica de superfície e pela técnica de imersão. Posteriormente as lâminas foram visualizadas em microscópio óptico comum e a resolução das imagens e características tintoriais foram avaliadas e registradas. A técnica de coloração por imersão, tanto para a coloração de Gram quanto para Wirtz-Conklin, evitou desperdício dos corantes utilizados nas técnicas, bem como, a saturação das soluções após muitas passagens de lâminas. Assim, a técnica de coloração por imersão é favorável para o uso nas aulas ou nos laboratórios de microbiologia. A aplicação dessa técnica mostrou resultados significativos para a diminuição do desperdício e, consequentemente, os impactos ao meio ambiente e à economia das instituições de ensino.Research, Society and Development2021-07-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1758510.33448/rsd-v10i9.17585Research, Society and Development; Vol. 10 No. 9; e9510917585Research, Society and Development; Vol. 10 Núm. 9; e9510917585Research, Society and Development; v. 10 n. 9; e95109175852525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/17585/16034Copyright (c) 2021 Fabricio Ueda Reine; Lorena Aparecida Bianchi de Souza; Jéssica Lima de Menezes; Rosana Ferreira Carli Cangussu Gomes; Aline Campos Reis de Souza; Camila Alves Mota; Benício Alves de Abreu Filhohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessReine, Fabricio UedaSouza, Lorena Aparecida Bianchi de Menezes, Jéssica Lima de Gomes, Rosana Ferreira Carli Cangussu Souza, Aline Campos Reis de Mota, Camila Alves Abreu Filho, Benício Alves de2021-09-12T14:28:06Zoai:ojs.pkp.sfu.ca:article/17585Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:54.087360Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
