Final answer:
The skin infections impetigo and Lyme disease are examples that can cause bullae. Impetigo leads to fluid-filled blisters, while Lyme disease can cause a bullseye rash.
Step-by-step explanation:
Examples of something that can cause bullae include the skin infections impetigo and Lyme disease. Impetigo, particularly the bullous type, leads to the formation of large, fluid-filled blisters around the nose and mouth that may rupture and become encrusted sores. The disease is commonly caused by bacteria like Staphylococcus aureus and S. pyogenes. Lyme disease can also cause a bullseye-shaped rash and it is caused by the Gram-negative spirochete bacterium of the genus Borrelia, which, untreated, can result in chronic disorders.
