What bacteria requires vitamins or minerals to grow?

Certain bacteria, known as auxotrophs, require specific vitamins or minerals for growth due to their inability to synthesize them. For example, Neisseria gonorrhoeae needs vitamins like niacin and certain amino acids, while Haemophilus influenzae requires factors like hemin (X factor) and nicotinamide adenine dinucleotide (NAD, V factor). These requirements often stem from their evolutionary adaptations to parasitic or symbiotic lifestyles, where they obtain nutrients from their hosts or environments.
