Oral rabies vaccine-laden baits, with a tetracycline biomarker, were distributed in Pinellas County (Florida, USA) by helicopter drop and from cars from January to April 1997. A total of 130,320 baits was distributed throughout the county, yielding an average bait density of 185 baits per km2. Bait ingestion was estimated by microscopic detection of tetracycline in tooth and bone samples from 244 raccoons (Procyon lotor), 33 opossums (Didelphis virginianus), 31 feral cats, and two gray foxes… 

Evaluation of Bait Station Density for Oral Rabies Vaccination of Raccoons in Urban and Rural Habitats in Florida

The results suggest that, in urban settings, bait stations deployed at densities of >1/km2 are likely to achieve higher seroprevalence as an index of population immunity critical to successful raccoon rabies control.

Taking the bait: species taking oral rabies vaccine baits intended for raccoons

Raccoon rabies in eastern USA is managed by strategically distributing oral rabies vaccine (ORV) baits through investigating/removing fish-meal polymer and coated sachet baits applied to simulate two aerial bait distribution densities, and non-target species visitation was examined.

EVALUATION AND SIGNIFICANCE OF TETRACYCLINE STABILITY IN RABIES VACCINE BAITS

The results of this study suggest that approximately 40% of the target quantity of tetracycline was unavailable for absorption, which could contribute to low biomarker detection rates and suggests that formulation modification should be considered.

Comparison of Suburban Vaccine Distribution Strategies to Control Raccoon Rabies

Bait stations could be used as part of an integrated rabies control strategy and no statistically significant differences existed between baiting strategies and frequencies of biomarker and antibody-positive raccoons across all years combined.

Bait acceptability for delivery of oral rabies vaccine to free-ranging dogs on the Navajo and Hopi Nations.

Evaluated the effectiveness of commercially available baits to deliver oral rabies vaccine to feral and free-ranging dogs on the Navajo and Hopi Nations, finding the fish-meal-crumble coated sachets having the highest acceptance rate of the tested baits.

Management of raccoon roundworm in free‐ranging raccoon populations via anthelmintic baiting

The rapid removal of baits despite repeated bait exposure suggests that habituation did not result in bait aversion and fishmeal baits are a viable delivery system for mitigation of raccoon-borne diseases requiring repeated treatments.

Evaluation of an oral vaccination program to control raccoon rabies in a suburbanized landscape

We evaluated the efficacy of an oral rabies vaccination (ORV) program conducted in Erie County, New York, from July through September, 2002–2005. Ingress of the raccoon (Procyon lotor) rabies variant

ORAL RABIES VACCINE (ORV) BAIT UPTAKE BY CAPTIVE STRIPED SKUNKS

To make baits attractive to skunks and to ensure puncture of the VC, modifications to current baits should consider a smaller size, a meat-flavored matrix, a slightly pressurized VC, and a direct coating of matrix on the VC.

A NEW FLAVOR-COATED SACHET BAIT FOR DELIVERING ORAL RABIES VACCINE TO RACCOONS AND COYOTES

Research was conducted during 1996–2000 to develop baits for delivering an oral rabies vaccine to raccoons and coyotes and found that coyotes preferred poultry, cheese/beef tallow, and fish-flavored sachet baits and that such baits were taken at the same rate as polymer baits.

EFFECT OF HIGH-DENSITY ORAL RABIES VACCINE BAITING ON RABIES VIRUS NEUTRALIZING ANTIBODY RESPONSE IN RACCOONS (PROCYON LOTOR)

Virginia opossums were abundant in the study area and were a potentially important nontarget species that competed for oral rabies vaccine baits, but the ratio of opossum to raccoons in this study did not affect rabies virus neutralizing antibody response of the raccoon populations.

A STUDY OF TECHNIQUES FOR THE DISTRIBUTION OF ORAL RABIES VACCINE TO WILD RACCOON POPULATIONS

This study evaluates a technique for delivering an oral rabies vaccine to wild raccoon (Procyon lotor) populations in two distinct physiographic regions of Virginia (USA), the coastal plain and the Piedmont plateau.

ORAL RABIES VACCINE CONTACT BY RACCOONS AND NONTARGET SPECIES IN A FIELD TRIAL IN FLORIDA

Free-ranging animal contact with baits containing a vaccinia virus recombinant vaccine expressing the rabies glycoprotein gene (V-RG) was monitored in Pinellas County from February through May 1997, and bait contact by all animals was significantly different among the four land use zones.

Prior to a limited field application of an orally-administered vaccinia-rabies glycoprotein (V-RG) recombinant virus vaccine for wildlife, background data were obtained for the proposed site on Parramore Island, Virginia, to assess the effect of proposed oral vaccination with V-RG vaccine.

Compared with uniform bait distribution, targeting raccoon habitats increased vaccination rates, and an approximate vaccination rate of 63% was sufficient to halt the spread of rabies in free-ranging raccoons.

It was unlikely that coyote bait consumption rates were overestimated because of coyotes secondarily marking themselves by ingesting prey items that consumed baits.

It is suggested that a large proportion of a free-ranging island raccoon population can be selectively and safely targeted, marked and monitored utilizing a proposed oral bait delivery system for recombinant or other rabies vaccines.

WILD CARNIVORE ACCEPTANCE OF BAITS FOR DELIVERY OF LIQUID RABIES VACCINE

The rapidity with which foxes picked up their first bait appeared more affected by unknown characteristics of years or study areas than by experimental variables, which has potential for field control of rabies, although higher acceptance will be desirable.

EFFICACY OF AN ORAL VACCINIA-RABIES GLYCOPROTEIN RECOMBINANT VACCINE IN CONTROLLING EPIDEMIC RACCOON RABIES IN NEW JERSEY

The breach of the vaccination area resulted in a resumption of the high rate of epidemic movement and a significant nine-fold increase in rabies prevalence, and insufficient funding and a decision to discontinue the program in 1994 may have contributed to the eventual breached of the barrier.

Results of an oral rabies vaccination program for coyotes.

The number of rabies cases in the target area decreased, and expansion of the epizootic area ceased, and mass distribution of an oral rabies vaccine in a palatable bait is an effective means to halt expansion of a rabies epizootsic involving coyotes.

It is concluded that oral baiting of mongooses is a feasible method for delivery of vaccines for the control of rabies in this species.
