Table 1 Common pathogens associated with infection in sickle cell anemia with underlying mechanisms for predisposition

Pathogen	Predisposing factors
Encapsulated bacteria (e.g., Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Salmonella spp)	Impaired splenic function
Impaired opsonization
Salmonellae	Recurrent vaso-occlusion with intestinal infarct, necrosis and increased gut permeability
Decreased neutrophil killing
Malaria	Decreased deoxyhemoglobin solubility
Parvovirus	Increased red cell turnover
Hepatitis B, C	Multiple blood transfusion
Chlamydophila	Unknown
Yersinia enterocolitica	Iron overload
Mycoplasma	Unknown
Edwardsiella tarda	Increased intestinal permeability and biliary sludging
