▪ Abstract Most aphids possess intracellular bacteria of the genus Buchnera. The bacteria
are transmitted vertically via the aphid ovary, and the association is obligate for both …

Rickettsial diseases, important causes of illness and death worldwide, exist primarily in
endemic and enzootic foci that occasionally give rise to sporadic or seasonal outbreaks …

Arthopods such as Ixodes scapularis ticks serve as vectors for many human pathogens. The
arthropod gut presents a pivotal microbial entry point and determines pathogen colonization …

The best-known members of the bacterial genus Rickettsia are associates of blood-feeding
arthropods that are pathogenic when transmitted to vertebrates. These species include the …

Abstract The Lyme disease agent Borrelia burgdorferi naturally persists in a cycle that
primarily involves ticks and mammals. We have now identified a tick receptor (TROSPA) that …

Outer surface protein C (OspC) is a differentially expressed major surface lipoprotein of
Borrelia burgdorferi. ospC is swiftly upregulated when spirochetes leave the Ixodes …

▪ Abstract This review summarizes the literature about pathogens and predators of ticks and
their potential use as biocontrol agents published since the beginning of this century. In …

The role of the host plasminogen activation system in transmission of and invasion by
Borrelia burgdorferi, the tick-borne spirochetal agent of Lyme disease, was investigated …

Spotted fever group Rickettsiae are predominantly transmitted by ticks. Rickettsiae have
developed many strategies to adapt to different environmental conditions, including those …

The multifunctional, morphologically complex salivary glands are essential to the biological
success of ticks and are intricately involved in the transmission of pathogens. They are …
