Simple vs. higher bacteria: filamentous: microbacterium, actinomyces, nocardia, simple, unicellular: most bacteria. Obligate intracellular vs free living: obligate intracellular: chlamydia, coxiella, ehrlichia, rickettsia. Coxiella (syphilis treated with mercury, made people crazy ex. Most bacteria are not intracellular they are free living. If you have to put someone on high levels in icu of oxygen end up with adult respiratory distress syndrome therefore pulmonary fibrosis. Inner and outer membranes (multiple: lps (lipopolysaccharides, porin proteins, thin peptidoglycan layer. Shapes of bacteria: cocci (chains vs clusters, rods (bacilli, short rods (coccobacilli, curved, spiral, branched (filamentous) Line like structure= flagella (characteristic of motile aerobic gram negative rods called enteriobacteriogeniceceae)
