Microbiology begins with the study of bacteria, yeasts, molds, viruses, and parasites - the microbes; how they are isolated, cultivated, and identified. The next level of study considers them as individual living systems, their physiology and genetics. The third level of study, the working level of a modern microbiologist, is concerned with how microbes interact with living and non-living elements and how these interactions may be controlled, modified, or expanded to benefit the environment and humanity. Microbiology majors identifying "unknown pathogens" in Medical Bacteriology lab. Our Bachelor of Arts degree is designed to be flexible, and yet provide disciplinary breadth for pre-professional students and students interested in an entry-level career in microbiology, the life or health sciences, or environmental sciences.

Contributors to Microbiology. Many scientists contributed to the science of Microbiology from the 17 th century to the present day. Some prominent microbiologists who have made significant contribution to the study of microorganisms are given below:. Antony Van Leeuwenhoek of Holland Figure 1. He was a Dutch merchant and a skilled lens maker. He made a variety of lenses with magnifying power X. He was the first person to invent simple microscope.
Microbiology has had a long, rich history, initially centered in the causes of infectious diseases but now including practical applications of the science. Many individuals have made significant contributions to the development of microbiology. Early history of microbiology. He is reputed to have observed strands of fungi among the specimens of cells he viewed. In the s and the decades thereafter, a Dutch merchant named Anton van Leeuwenhoek made careful observations of microscopic organisms, which he called animalcules. Until his death in , van Leeuwenhoek revealed the microscopic world to scientists of the day and is regarded as one of the first to provide accurate descriptions of protozoa, fungi, and bacteria. After van Leeuwenhoek died, the study of microbiology did not develop rapidly because microscopes were rare and the interest in microorganisms was not high.
Microbiology: past, present and future
Pre-microbiology, the possibility that microorganisms existed was discussed for many centuries before their actual discovery in the 17 th century. In his first century book, On Agriculture, Roman scholar Marcus Terentius Varro was the first known to suggest the possibility of disease spreading by yet unseen organisms. In , Girolamo Fracastoro proposed that epidemic diseases were caused by transferable seed-like entities that could transmit infection by direct or indirect contact, or even without contact over long distances. All these early claims about the existence of microorganisms were speculative and were not based on any data or science.
