A very complex science, Microbiology deals with the study of microscopic organisms, usually focusing on the immune system and the viruses and bacteria that attack it. This branch encompasses many smaller areas of study, including virology, parasitology, bacteriology, mycology and immunology where a microbiologist can specialise in. A lot of time spent using microscopes in the lab, this branch doesn't require the same amount of field work as say geology or other life sciences. As research into these areas is increasing, it is believed that microbiologists will be in high demand very soon. Not only do they work on finding the causes for illnesses, but they also work on developing antibiotics and vaccines.
In non-medically related work, microbes also effect climate change, such as methane production contributing to global warming. Microbiologists work to harness this, turning it into alternative fuels to save the atmosphere. Microbes have also been used to clean up man made disasters such as oil spills.
Clinical microbiologists work on preventing and treating bacterial, fungal, viral and parasitic disease in labs or pathology department in both universities and hospitals. The Health Protection Agency is also another big employer as well as companies hiring microbiologists to conduct research on agricultural or environmental impacts of business.
In addition to holding a bachelor's degree in a similar science, specialised training through the Clinical Scientist Training Scheme is required to work in the field. Though if lab work doesn't appeal, many microbiologists bring their degrees and training into other areas such as law, communications industry and education.
