title: Ovarian intercellular bridges in Dermacentor andersoni stiles (Acari : Ixodidae).
abstract: Intercellular bridges are present between oogonia and between oocytes of nymphs and newly molted and fasting adult Dermacentor andersoni Stiles. During these stages there is synchronous development of oogonia and oocytes. These bridges are unique both in their degree of development and in possessing narrow, elongated invaginations of the plasma membrane around both bases. Dictyosomes are frequently present in close proximity to bridge bases and vesicles are often noted in bridges between oocytes of adults. Bridges between oogonia infrequently contain cisternae of smooth endoplasmic reticulum.
