We proposed in the Basic Microbiology Subject for food science and nutrition students, a “hands-on” activity consisting on sampling student's hands for bacterial presence and identification. This is a project to be implemented in multiple laboratory classes throughout the semester, allowing students to learn, and apply general microbiology techniques in mixed or isolated cultures obtained from their own samples in parallel with those from the laboratory collection proposed in the microbiology syllabus (as aseptic technique, hands sampling, streaking for single-colony isolation, culture medium analysis, bacterial morphology, and biochemical study, employ of dichotomous keys) This activity will allow them to understand the association between humans and microorganisms, to recognize the importance of personal hygiene (for example, hand-washing), and to know how hands can be an important vehicle for bacterial spreading in surrounding environments (for example, kitchen, health-care setting). The fact that the isolates for practical work were not only from laboratory collections, but also from the personal student's hands, keeps them interested in discover and study their own bacteria to know their main characteristics and the potential importance to human health, through spread of hazardous isolates. This project also potentially contributed for student's development of other skills such as autonomy and teamwork, planning and write, communication, and debate.

促进微生物学的参与和学习：学生手中细菌的存在和鉴定

我们在面向食品科学和营养学学生的“基础微生物学”主题中提出了一项“动手实践”活动，该活动包括对学生的手进行采样以了解细菌的存在和鉴定。这是一个在整个学期中将在多个实验室课程中实施的项目，允许学生在从自己的样本中获得的混合或分离培养物中学习并应用常规微生物学技术，并与在微生物课程提纲中提议的实验室收集的那些并行进行无菌技术，手采样，划线进行单菌落分离，培养基分析，细菌形态学和生化研究，使用二分法键）此活动将使他们了解人与微生物之间的联系，认识到个人卫生的重要性（例如洗手），并了解手如何成为细菌在周围环境中传播的重要工具（例如，厨房，医疗场所）。用于实际工作的分离株不仅来自实验室收集物，而且来自私人学生的手，这使他们对发现和研究自己的细菌感兴趣，从而了解它们的主要特征以及通过传播有害物质对人类健康的潜在重要性的兴趣。隔离株。该项目还可能有助于学生发展其他技能，例如自主性和团队合作力，计划和写作，沟通和辩论。用于实际工作的分离株不仅来自实验室收集物，而且来自私人学生的手，这使他们对发现和研究自己的细菌感兴趣，从而了解它们的主要特征以及通过传播有害物质对人类健康的潜在重要性的兴趣。隔离株。该项目还可能有助于学生发展其他技能，例如自主性和团队合作力，计划和写作，沟通和辩论。用于实际工作的分离株不仅来自实验室收集物，而且来自私人学生的手，这使他们对发现和研究自己的细菌感兴趣，从而了解它们的主要特征以及通过传播有害物质对人类健康的潜在重要性的兴趣。隔离株。该项目还可能有助于学生发展其他技能，例如自主性和团队合作力，计划和写作，沟通和辩论。
