EXAMINATION OF BACTERIA

In the examination of bacteria, the shape and the morbidity can be examine with the aid of microscope, without staining reagent introduce into the sample or specimen. But in other to disclose invisible structure of the cells, staining technique are needed. The staining reveals the cluster structure of the bacteria. The same bacteria are stubborn in the sense that even with the staining, their structure still remains invisible. In this type of bacteria, complex technique is needed; i.e. the application of electron microscope. Bacteria organism is group into gram positive and gram negative. The group of the bacteria into gram- positive and negative staining technique is required. the staining will help to identify and assign the bacteria group which they belong to
