Therapy with avermectines and diazinon of psoroptic mange in sheep from Transylvania, Romania
In a study of three acaricides, doramectin (Dectomax ® , Pfizer) used at a single dose of 300 μg/kg b.w. given intramuscularly showed a high efficacy (95%) against Psoroptes ovis, in naturally infected sheep. All doramectin treated animals were clinically normal and all skin scrapings were negative for mites 50 days after treatment. At the end of experiment (70 days) only 5% of the animals showed skin lesions and a low infestation score (1+), compared to 10% for ivermectin (Romavermectine ® , Romvac Company S.A. Bucharest) and 20% for diazinon (Scabizol ® , Romvac Company S.A. Bucharest). The three treatment groups were continually in contact with infested sheep during the study.

The ear mite “Psoroptes cuniculi” is the main cause of ear mange, a highly contagious parasitic skin disease in rabbits all over the world. In the current work, a preliminary therapeutic trial to study the effect of the broad use acaricides doramectin and ivermectin on P. cuniculi was performed on artificially infested rabbits. Twenty five adult New Zealand white rabbits were used in this study. The rabbits were assigned randomly into five groups/ 5 rabbits in each group. Each rabbit was experimentally infested with 100 mites/ ear. The first group was designated the positive control group and was not treated. The second and third groups were treated with doramectin 200 and 400 μg/kg bw, respectively. Groups 4 and 5 were treated by dressing with ivermectin in one dose and 2 doses with a 1 week interval. After the therapy, all rabbits were examined microscopically on the 7th, 14th, and 28th day post treatment and the number of live mites (larvae, nymphs, and adults) on each rabbit was...

In the current report, a preliminary observation to study the adverse effects of the broad use acaricides fipronil (FPN) in rabbits infested with Psoroptes cuniculi. Two separate groups (5 rabbits/each) treated topically (poured on at the base of the neck) with fipronil 5%, 1 vial/ 10 kilogram body weight (kg bw) and 1 vial/ 5 kg bw. After FPN spot on application, rabbits in both groups examined microscopically on the 7th, 14th, and 28th day post treatment and the number of live mites (larvae, nymphs, and adults) on each rabbit counted at the end of the experiment (28th day). The results showed that the number of mites in rabbits topically treated with FPN did not show significant decrease, moreover a decrease in both treated rabbits body weight (bw) and in performance observed clearly, with some attendant mortality. In conclusion, this work showed that FPN was with limited efficacy on P. cuniculi and had some undesirable side effects. Further and in-depth studies on FPN toxicity in...

Background: The present study was conducted to evaluate the therapeutic efficacy of fipronil, ivermectin and clove oil against frequently reported Psoroptes cuniculi mites which are responsible for causing intense pruritus and scab formation on skin, ear pinna and ear canal in domestic rabbits (Oryctolagus cuniculus). Methods: The rabbits were divided into 3 groups viz. A, B and C each having 10 rabbits. These groups were topically treated with fipronil, ivermectin and clove oil on days 0, 7, 14 and 21. Pre and post treatment evaluations were made on the basis of clinical improvement and microscopic examination of skin scrapings in each group. Conclusion: Results revealed that all 3 drugs were effective against P. cuniculi; but ivermectin led recovery was quicker than rest of the two drugs. All three groups were free of lesions and mites on day 21 of treatment.
