Ethical issues facing microbiologists could be considered in two parts. The first relates to the way the ethical issues during their laboratory work. The second pertains to ethical issues on the data/reports they generate for the patients or in research. In both segments, there is pressure to perform, which is exerted by both, the community, as well as peers. It has therefore become increasingly necessary to recognize the facts that unethical actions might be a frequent reality. Since some of these activities generate serious ethical concerns, both in practice and research, it is necessary for microbiologists to be aware and equipped to meet these issues in a prepared and measured way. In an attempt to highlight this requirement, this article outlines the important ethical issues and guidelines relevant to the field of Microbiology.
