While herpes infections are most frequently associated with Erythema Multiforme (EM), bacteria can also, although less commonly, cause it.
Here's a breakdown of bacteria and their association with erythema:
-
Mycoplasma pneumoniae: This is a bacterial species frequently associated with atypical pneumonia. It is also recognized as a trigger for Erythema Multiforme (EM), especially in children and young adults.
-
Streptococcus pyogenes: Infections caused by Streptococcus pyogenes (e.g., strep throat, scarlet fever) have been linked to EM in some instances.
-
Other Bacterial Infections: Less frequently, other bacterial infections might trigger EM. These cases often involve a complex interplay of factors, making it difficult to pinpoint a single causative agent.
It's important to note that while bacterial infections can be associated with erythema multiforme, they are not the most common cause. Viral infections, particularly herpes simplex virus (HSV), are the most frequent triggers. Additionally, drug reactions are also a frequent cause.
Therefore, while herpes simplex virus (HSV) is the most common cause of erythema multiforme, some bacteria such as Mycoplasma pneumoniae and Streptococcus pyogenes can also be the cause.
