    Awesome job Rayann!!! You had a great presentation and poster. Ticks are interesting creatures.

    Well done, Rayann. Why do you think the nymphs that were analyzed were so much more likely to be infected? Are infected nymphs more likely to die before becoming adults?

      Im not entirely sure but if I had to guess I suppose that as ticks mature some may lose the bacteria. It could also potentially be due to an immature immune system among nymphs. But this is just speculation.

    Hi Rayann- interesting results! Do you have any ideas or potential explanations as to why rickettsia prevalence is so much higher in tick nymphs than adults? And does carrying the bacteria affect the health and survival of the ticks?

      The bacteria don’t seem to have negative effects on the ticks, they are just carriers.

    Nice job, Rayann! Interesting that the prevalence in nymphs is so much higher than it is in adults. Great job presenting.
