Streptococcus pneumoniae was the most common bacteria found in<unk>  before the development of antibiotics.  More recently, however, anaerobes have become the predominant organism in culture positive<unk>  (and therefore careful anaerobic cultures should always be sent when working up parapneumonic effusions).  Mixed aerobic and anaerobic infections are also common. In general any bacteria can cause an<unk> , however different bacteria are associated with different rates of<unk>  formation. Some of the common bacteria causes include; bacteroides, fusobacterium, haemophilus influenzae, pneumococcal infections, staphylococcus aureus, streptococcus, and TB.
