  3. Classifying Bacteria • How do we classify bacteria? • By 3 different shapes • Spherical Usually the simplest ones. These bacteria are called cocci (singular coccus). • Rod shaped These are known as bacilli (singular bacillus). • SpiralThese are known as spirilla(singular spirillus).

  4. Diseases CAUSED BY BACTERIA • Common bacterial diseases • leprosy, tetanus, syphilis, typhoid fever, strep throat, tuberculosis, salmonella, whooping cough

  5. VEctors • What is a vector? • Animal disease spreaders that don’t catch the illness • They carry infectious disease (can be passed from one generation to the next) • Examples… • Rats, ticks, and mosquitoes
