Which genus is listed together with Veillonella species?

Which genus is listed together with Veillonella species?

• A. Lactobacillus
• B. Veillonella
• C. Streptococcus
• D. Escherichia

Answer: (A)

Veillonella species rely on lactate as their main energy source. In environments like the oral cavity and dental plaque, lactic acid bacteria that produce lactate, especially Lactobacillus, are commonly found nearby. This creates a straightforward metabolic partnership: Lactobacillus generates lactate, and Veillonella consumes it. Because of this close metabolic relationship, Veillonella is often listed together with Lactobacillus in microbiology descriptions and practice questions. While Streptococcus also produces lactate and can be found with Veillonella, the pairing highlighted in this item is Lactobacillus due to the well-known lactate-based interaction.
