Rickettsia bellii sp. nov.: a Tick-Borne Rickettsia, Widely Distributed in the United States, That Is Distinct from the Spotted Fever and Typhus Biogroups
During studies to serotype tick-borne rickettsiae from various areas in the United States, particularly those areas associated with the vectors of Rickettsia rickettsii, we obtained 263 isolates of a…
New Blattisociid Mites (Acarina: Mesostigmata) Recovered from Neotropical Flowers and Hummingbirds' Nares
Eleven new species and two new genera of blattisociid mites are described from the nasal passages of tropical hummingbirds, from flowers, or from both and Phoresy, rather than parasitism, is suggested to explain the high incidence of these mites in the birds concerned.

The presence of C. ruminantium in nymphs and adults was confirmed by transmission of heartwater to goats and the DNA sequences of both probes were determined; synthetic oligonucleotides from pCS20 are recommended as DNA probes for C. tournaisianium.

Nine virus strains were recovered from a small group of tissues from the wild rodent Calomys callosus captured in the area of San Joaquin, Bolivia, in 1963 and shown to be serologically related to Machupo virus, the etiologic agent of Bolivian Hemorrhagic Fever.
Pheromone-mediation of host-selection in bont ticks (Amblyomma hebraeum koch).
The use of acaricides is unlikely to reduce bont tick populations in areas where adequate numbers of alternate (wild) hosts are present, and cattle so treated may lose their resistance to heartwater through lessened exposure to infected ticks.
Use of carbon dioxide and natural or synthetic aggregation-attachment pheromone of the bont tick,Amblyomma hebraeum, to attract and trap unfed adults in the field
The response of unfed adults to carbon dioxide and the aggregation-attachment pheromone presents an obvious host-location mechanism and a means for the ticks to discriminate between suitable hosts (those with males already attached) and potentially unsuitable hosts ( those with no males attached).

It is concluded that these important disease vectors respond positively to a variety of volatile chemicals, which may conceivably be used to attract them to traps, animals or acaricides in efforts to control ticks or the diseases they transmit.

Larval activity was restricted to a 9- to 11-week period between mid-June and early September, peaking once in late July or early August, and nymphal activity, already evident when trapping began, remained constant until it declined after mid-August.
