Two bait delivery systems for the oral immunization of dogs against rabies were tested in small scale field trials in a semi-rural area in Tunisia : bait delivery to owned dogs during door to door visits of households (door to door baiting) and distribution of baits on transect lines (transect line baiting).
A prototype bait (DBL2) configured for industrial production and containing either sulfadimethoxine (SDM) as a systemic marker or Rhodamine B as a topical marker was used.
The overall proportion of dogs which took a bait and presented topical marker staining after door to door baiting was 59.1%. The total time and costs spent per bait accepting dog averaged 34 person minutes and US$4, respectively.
Unconsummated baits were readily recovered.
No unprotected human contacts with baits were recorded.
Door to door baiting is a very specific but time-consuming method taht enables a safe administration of vaccine baits to owned dogs.
For transect line baiting, baits were distributed at a density of ca 3000 baits per km2 along double transect lines.
Baits were recovered after 20 h. According to the proportion of SDM positive serum samples, 24.1% of owned dogs in the baiting area had consumed baits.
Of all owned and ownerless dogs, presumably free-roaming during transect line baiting,>40% had consumed baits.
The total time and costs spent per bait accepting dog averaged 48 person minutes and ca US$20, respectively. (...)
