Which transport media is selective for Neisseria?

Transport media that is selective for Neisseria is specifically designed to support the growth of these organisms while inhibiting the proliferation of other bacteria. The correct choice, TM CO2, refers to Thayer-Martin media, which is enriched with nutrients and antibiotics that selectively allow for the growth of Neisseria species, particularly Neisseria gonorrhoeae and Neisseria meningitidis.

This media contains a combination of antibiotics that suppress the growth of competing flora, which is essential given that Neisseria are fastidious organisms and can be easily outgrown by other skin and mucosal flora. The carbon dioxide (CO2) atmosphere enhances the growth of Neisseria, as these bacteria thrive in such conditions.

Other types of media mentioned, such as CAP (Chocolate Agar Plate) and BAP (Blood Agar Plate), while supportive of overall bacterial growth, are not specifically selective for Neisseria. Additionally, MAC (MacConkey Agar) is designed to grow gram-negative bacteria and differentiate those that can ferment lactose, which does not cater to the selective growth needs of Neisseria species. Using TM CO2 provides an ideal environment for the recovery and identification of Neisseria in clinical specimens.
