- Lab 12: Isolation and Identification of Enterobacteriaceae and Pseudomonas, Part 1
- Labs 12 and 13 deal with opportunistic and pathogenic fermentative Gram-negative bacilli that are members of the bacterial family Enterobactereaceae, as well as nonfermentative Gram-negative bacilli such as Pseudomonas and Acinetobacter.
- Lab 16: Isolation and Identification of Neisseriae, Mycobacteria, and Obligate Anaerobes
- The neisseriae are a group of Gram-negative diplococci 0.6-1.5 µm in diameter (see Fig. 1A). Two species of Neisseria, N. gonorrhoeae and N. meningitidis, are considered as true human pathogens. Both of these organisms possess pili and adhesins for adherence to host cells, produce endotoxins, and resist destruction within phagocytes. N. meningitidis also produces a capsule to resist phagocytic engulfment.
