Introduction: Foxes are a reservoir of parasites that are dangerous to humans. The aim of the study was to determine the parameters associated with the occurrence of tapeworms in red foxes in north-western Poland. Material and Methods: Parasitological sections were taken from 620 red foxes using IST and SCT methods in 18 districts of West Pomerania Province. Results: The extensity of fox infection with tapeworms was 61%. Echinococcus multilocularis, Mesocestoides spp., Dipylidium caninum, and specimens of the genus Taenia were identified. E. multilocularis was found in 11 districts. Mesocestoides spp. demonstrated the highest prevalence (41.3%), while E. multilocularis demonstrated the lowest prevalence (2.9%); however, it infected foxes with the greatest mean intensity (235.6 tapeworms per fox). The most common co-occurrence in a single host organism was observed for Mesocestoides spp. and tapeworms of the genus Taenia; however, no examples were found of coinfection by E. multilocularis and D. caninum. Conclusion: The occurrence of tapeworms in foxes was high in West Pomerania Province and was often higher than observed in previous years. For this reason, the risk of parasite transmission to humans and domestic animals is mounting. The risk of infection is also amplifying due to the growth of the fox population.

Afficher plus [+] Moins [-]Dose titration and confirmation tests for determination of cesticidal efficacy of epsiprantel in dogs
1989
Corwin, R.M. | Green, S.P. | Keefe, T.J.
Fifty-five dogs, naturally infected with Taenia sp or Dipylidium caninum or both, were assigned to the following treatment groups for dose titration studies with epsiprantel: nonmedicated control dogs (n = 14), medicated dogs given a dosage of 2.75 mg/kg of body weight (n = 15), medicated dogs given a dosage of 5.5 mg/kg (n = 16), and medicated dogs given a dosage of 8.25 mg/kg (n = 10). Medication was given orally in a tablet formulation. Feces were examined for cestodes passed and the gastrointestinal tract was examined at necropsy for retained cestodes. Efficacy of epsiprantel was 92.9% against Taenia and 44.8% against Dipylidium for a dosage of 2.75 mg/kg, 100% against Taenia and 99.8% against Dipylidium for a dosage of 5.5 mg/kg, and 94.6% against Taenia and 100% against Dipylidium for a dosage of 8.25 mg/kg. For dose confirmation, 36 dogs naturally infected with Taenia sp or D caninum or both were allotted to 2 treatment groups: nomedicated control dogs (n = 16) and dogs medicated with epsiprantel at a dosage of 5.5 mg/kg (n = 20). Efficacy was 100% for both Taenia sp and D caninum.

Twenty-six mixed-breed (14 males, 12 females) dogswere used in a double-blind study to evaluate the effect of milbemycin oxime against naturally acquired infection with Ancylostoma caninum. Dogs were ranked and paired, on the basis of number of hookworm eggs/g of feces, and treatment was randomly assigned. Each dog was given either the study drug or placebo (1 tablet/11.4 kg [0.5 mg/kg] of body weight). Eggs per gram of feces enumeration was done on days 3 and 7 after treatment, and dogs were euthanatized on day 7. On day 3, 5 of the 13 dogs in the milbemycin-treated group had hookworm eggs in the feces (results of the McMaster test). In these dogs, mean number of eggs per gram of feces had decreased markedly (from 5,289 to 452) and, by day 7, was 114. At necropsy, 16 A caninum adults were recovered from 2 of the milbemycin-treated dogs. On day 3, 12 of the 13 dogs in the placebo-treated group had hookworm eggs in the feces. Mean number of eggs per gram of feces in these dogs decreased slightly (from 5,243 to 2,646), but did not decrease further by day 7. A mean number of 54.4 A caninum adults was recovered from 12 of the 13 placebo-treated dogs at necropsy. Milbemycin oxime had 97.8% efficacy against A caninum. Results also indicated that milbemycin oxime may be effective against Trichuris vulpis, but not against Dipylidium caninum.

Craig, T.M. | Mercer, S.H. | Wade, C.G. | Lynn, R.C.
Eighteen dogs with naturally acquired helminth infections were used to evaluate the efficacy of nitroscanate against Ancylostoma caninum, Dipylidium caninum, and Trichuris vulpis. Approximately 15 minutes before treatment, the dogs were given 100 to 200 g of canned dog food. Ten dogs were treated with nitroscanate (50 mg/kg of body weight, PO), and 8 dogs were given placebo tablets PO. The dogs were euthanatized and necropsied 10 days after treatment and helminths were recovered from the small intestine and cecum. On the basis of the number of worms recovered from treated dogs vs the number recovered from control dogs, we determined the efficacy of nitroscanate to be 99.6% against A caninum, 99.8% against D caninum, and 0% against T vulpis.
