Q

babesia lifecycle detailed

A
  • Sporozoites released from tick salivary gland -> Invade erythrocytes -> Become trophozoites -> Pair of merozoites made -> Female tick bloodmeal ingests infected erythrocytes & syngamy in tick gut -> Penetrate gut epithelium & produce merozoites -> Undergo secondary merogony & find their way into ova -> Oviposition constitutes infected eggs -> Replication in gut of infected larva -> Invade salivary glands & sporogony to produce sporozoites
