Coinfection of blacklegged ticks (Acari: Ixodidae) in Dutchess County, New York, with the agents of Lyme disease and human granulocytic ehrlichiosis.

Adult blacklegged ticks, Ixodes scapularis Say, collected from forested sites in Dutchess County, NY, were tested for infection with the etiologic agents of Lyme disease, Borrelia burgdorferi Johnson, Schmid, Hyde, Steigerwalt & Brenner, and human granulocytic ehrlichiosis (HGE). Rates of infection with the 2 pathogens were high and independent of one another, confirming prior findings and suggesting that a variety of hosts may be competent reservoirs of the HGE agent.

Effects of chronic lithium administration on concanavalin A binding to plasma membranes from the corpus striatum of rat brain.

The effects of chronic in vivo lithium administration on mannose-containing components of plasma membranes from rat corpus striatum were examined by a 3H-concanavalin A binding displacement method. No difference on Con A binding was observed between sodium or lithium-treated rats during a 1-month period.
