Classification of Bacteria of Medical Importance that give Gram-negative Reaction This classification was carried out in 1986 and placed spirochetes, spiral and curved, aerobic bacteria and facultatively aerobic rods, obligate anaerobic bacteria, aerobic and anaerobic cocci, sulfate and sulfur-reducing, rickettsias, clamydias, and mycoplasmas in this group. Example: -Pseudomonas. Microscopic organisms, commonly known as microorganisms or microbes, are found all around us and even inside our bodies. In biology, the field of taxonomy is tasked with describing, naming, and classifying organisms; the latter according to some metrics of similarity. Fungi. Classification seeks to describe the diversity of bacterial species by naming and grouping organisms based on similarities. Different from parasites and fungi (eukaryotic) •Prokaryotic organisms –simple unicellular organisms –no nuclear membrane –no mitochondria –no Golgi bodies –no endoplastic reticulum •Complex cell wall –Gram-positive –Gram-negative.
