103 Lecture Notes - Lecture 3: Mycoplasma, Saprotrophic Nutrition, Humus
Document Summary
These organisms were first discovered by pasteur in eighteenth century when he studied the causative agent of the. Bovine pleuropneumonia (a pulmonary disease of cattle which appeared in germany and. Due to its resemblance with pneumonia symptoms this disease is called as. He believed that the disease was caused by some microbe but he could neither observe it nor could culture it. However, it was believed that the causal agent was pleuropneumonia like organisms (pplo). This causal agent was first isolated and cultured by e. nocard and e. r. roux in 1898. They established that these causal agents of pleuropneumonia can grow on complex nutrient media which do not contain cells. They also observed that these organisms show different forms, when grown on the culture media. These organisms were named as asterococcus mycoides by borrel et. al (1910). Mycoplasma was given by nowak (1929) due to their fungi like resemblance.
