DNAJC5 and parasitic infectious disease: The recent analysis of csp sequences and clone multiplicity in 521 parasite isolates from Mozambique children under 5 years who participated in a large Phase II study of the efficacy of RTS,S/AS02A confirmed the previous finding of no significant effect of csp sequences but found a small but significant decrease in the multiplicity of infections in post-vaccination parasitemias among those with asymptomatic infections who had received RTS,S/AS02A[18], [26].
