Also occur with other agents, including Streptococcus pneumoniae, Haemophilus influenzae, Escherichia coli, group Astreptococci, Serratia marcescens, Klebsiella pneumoniae, adenovirus, and tuberculosis" Pneumatocele formation is associated with hyperimmunoglobulin E (IgE) syndrome (Buckley- Job syndrome).
