A recent study published in Ticks and Tick-Borne Diseases compared the efficacy of transmission routes, both horizontal (between life stages of developing ticks) and transovarial (from infected female tick to larvae), of Borrelia miyamotoi from Ixodes scapularis (blacklegged ticks). Results show that although multiple transmission routes contribute to maintenance of B. miyamotoi in the ecosystem, transovarial transmission is likely the primary contributing factor to infected ticks in nature.
Authors suggest that risk assessment and tick control strategies should target adult female ticks.
