¶ … Microorganisms Through a Microscope
The Gram stain test distinguishes two fundamental cell varieties of bacteria. The latter also determines the presence of bacteria. "Gram-positive" refers to the type that retains the original crystal violet stain. In contrast, the decolorized stain red depicts the "gram-negative" variety. The significance of the staining plays a crucial role in the determination of the appropriate treatment for an infection. Often, the clarity in distinguishing between viral, fungal, and bacterial infections may not be attained (Wojewoda et al. 2073). This requires the application of the gram stain test. Additionally, various bacterial varieties may necessitate the use of different treatments. The use of gram stain technique enables physicians to establish that the infection is because of bacteria. The test also provides fast results that are beneficial for the diagnosis process.
The acid-fast stain can be used to identify microbes in the genera Mycobacterium and Nocardia. A majority of the bacteria emerging from the genera Mycobacterium and Nocardia result in...
prokaryotes consist of millions of genetically distinct unicellular organisms. A procaryotic cell has five essential structural components: a genome (DNA), ribosomes, cell membrane, cell wall, and some sort of surface layer which may or may not be an inherent part of the wall (1). Functional aspects of procaryotic cells are related directly to the structure and organization of the macromolecules in their cell make-up, i.e., DNA, RNA, phospholipids, proteins
