  • Title: Stochastic Chlamydia Dynamics and Optimal Spread.
    Author: Enciso G, Sütterlin C, Tan M, Wan FYM.
    Journal: Bull Math Biol; 2021 Feb 17; 83(4):24. PubMed ID: 33594486.
    Abstract:
    Chlamydia trachomatis is an important bacterial pathogen that has an unusual developmental switch from a dividing form (reticulate body or RB) to an infectious form (elementary body or EB). RBs replicate by binary fission within an infected host cell, but there is a delay before RBs convert into EBs for spread to a new host cell. We developed stochastic optimal control models of the Chlamydia developmental cycle to examine factors that control the number of EBs produced. These factors included the probability and timing of conversion, and the duration of the developmental cycle before the host cell lyses. Our mathematical analysis shows that the observed delay in RB-to-EB conversion is important for maximizing EB production by the end of the intracellular infection.
