Which organism is NOT commonly implicated in subpectoral abscess?

Explanation:
Subpectoral abscesses are typically caused by skin and soft-tissue flora invading the chest wall, with Staphylococcus aureus and streptococci being the most common culprits. Escherichia coli is an enteric organism and is not usually involved in chest-wall abscesses; it’s more associated with abdominal, urinary, or GI sources. So, while Staphylococcus aureus and hemolytic streptococci (including Streptococcus pyogenes) are classic organisms in this setting, Escherichia coli is not commonly implicated.
