These types of transmission represent how generations or life stages of infected ticks ...
By doing so, R. rickettsii also increases its transmission abilities. Without this process in place, the pathogen may not survive long enough in the vector to properly replicate and infect other hosts.

Furthermore, the percentage of patients hospitalized was lower for R. parkeri than for R. rickettsii (33% vs 78%), and R. parkeri led to no deaths while R. rickettsii led to death in 7% of cases. [7] A 2021 systematic review of 32 confirmed and 45 probable cases of human infection with R. parkeri determined that 94% of the confirmed cases had ...
