Nocardioforms can degrade petroleum pollutants and produce the antibiotic vancomycin . An example is Treponema pallidum which causes syphilis. A tick-borne spirochete is responsible for Lyme disease. Typical bacteria are the bacteria which command much attention in this course, and will be discussed fully in the next major section. Ed. III, pp.
Some bacillus are so short that they are described as coccobacilli .
If bacteria are mobile it is because they have one or more flagella. Lower bacteria are submicroscopic in that they cannot be seen by the light microscope but can be seen by the electron microscope. They include mycoplasma, rickettsia, and chlamydia. Common bacterial pneumonia can be caused by Streptococcus pneumonia or Klebsiella pneumonia . These can be tested for relatively easily.
