GRAM-POSITIVE RODS

The Gram-positive rods in this section will be divided into three distinct varieties based upon their ability to produce endospores and their morphological appearance:

ENDOSPORE-FORMING
- BACILLUS
REGULAR, NON-ENDOSPORE-FORMING
- LACTOBACILLUS
- LISTERIA
- ERYSIPELOTHRIX
IRREGULAR, NON-ENDOSPORE-FORMING
- CORYNEBACTERIUM

These bacteria are ubiquitous in nature and most are aerobic or facultatively anaerobic.
