VIRUS NEUTRALIZING ANTIBODY FOLLOWING ORAL RABIES VACCINATION OF RACCOONS (PROCYON LOTOR) ON SUBURBAN LONG ISLAND, NEW YORK, USA.

Vaccine-laden baits were distributed to interrupt and halt raccoon (Procyon lotor) rabies transmission in suburban Nassau and Suffolk counties on Long Island, New York, US. Fishmeal polymer baits containing the RABORAL V-RG® vaccine were deployed with helicopters, bait stations, and vehicles at a target density of 250 baits/km2 during annual September campaigns (2006-10). Semiannual campaigns (500 baits/km2) were also initiated in a portion of the treatment zone (2007-09) in response to a persistent focus of rabid raccoons.

ORAL RABIES VACCINATION STRATEGIES TOWARD RACCOON (PROCYON LOTOR) RABIES ELIMINATION ON SUBURBAN LONG ISLAND, NEW YORK, USA.

Approximately 1.86 million baits containing a vaccinia-rabies glycoprotein recombinant vaccine were distributed with helicopters, vehicles, and bait stations during 2006-10. A bait density of 250 baits/km2 effectively controlled rabies cases in enzootic and preepizootic areas.

Rapid analytical technique to identify alpha emitting isotopes in water, air-filters, urine, and solid matrices using a Frisch Grid detector.

A 5-inch-diameter Frisch Grid gas-proportional ionization chamber was utilized at Brookhaven National Laboratory (BNL) to rapidly characterize and quantify alpha-emitting actinides in unprocessed water, soil, air-filter, urine, and solid matrices. Instrument calibrations for the various matrices were performed by spiking representative samples with National Institute of Standards and Technology traceable isotopes of 230Th, 232U, 236Pu, and 243Am. Detection efficiencies were typically 15-20% for solid matrices (soil, concrete, filters, dry urine) and 45% for mass-less water samples.
