2. PART 1. BACTERIA
 All organisms have a name consisting of two parts: the genus
followed by the species
 Bacteria have been grouped and named primarily on their
morphological and biochemical/metabolic differences.
 bacteria are now also being classified according to their
immunologic and genetic characteristics.

3. GRAM STAIN
Because bacteria are colorless and usually
invisible to light microscopy, colorful stains have
been developed to visualize them.
 Gram stain:
• which separates organisms into 2 groups: gram-
positive bugs and gram-negative bugs.

4. Gram-Positive
 Remember that there are 6 classic gram positive bugs that cause disease in humans
and basically every other organism is gram-negative.
 TWO are cocci
1. Streptococcus forms strips of cocci.
2. Staphylococcus forms clusters of cocci.
 FOUR are rod-shaped (bacilli).
 Two of the 4 gram-positive rods produce spores (spheres that protect a dormant
bacterium from the harsh environment). They are:
1. Bacillus
2. Clostridium
 The last 2 gram-positive rods do not form spores:
1. Corynebacterium
2. Listeria

5. Gram-Negative
Any bacteria doesn’t mentioned in previous slides
