Cultures of Staphylococcus supplies which of the following for cultures of Haemophilus?

Cultures of Staphylococcus provide V factor, which is essential for the growth of Haemophilus species. Haemophilus requires specific growth factors that are not found in standard media. The V factor, also known as the nicotinamide adenine dinucleotide (NAD), is crucial for cellular metabolism and energy production in Haemophilus bacteria.

When Staphylococcus is cultured on agar, it releases V factor into the surrounding medium, creating an environment where Haemophilus can thrive. This interaction is important in laboratory settings, particularly in mixed cultures where Haemophilus species may be difficult to isolate or cultivate due to their stringent growth requirements.

Other factors, such as X factor, are related to different nutritional requirements of certain organisms. For instance, X factor (hemin) is important for some other bacteria, but it is not provided by Staphylococcus. Understanding this relationship helps microbiologists effectively culture and study Haemophilus species in clinical and research settings.
