Abstract

Pesq. Vet. Bras. 34(9):832-836, setembro 2014 832 RESUMO.-O objetivo do trabalho foi avaliar a eficácia da ivermectina administrada por via oral no controle de Psoroptes ovis e Leporacarus gibbus em coelhos naturalmente infestados. Foram selecionados 20 coelhos adultos, distribuídos na mesma proporção de ambos os sexos, em dois grupos experimentais, compondo dez animais por grupo. No grupo controle foi administrado o mesmo volume do tratamento de solução salina, enquanto o grupo tratado recebeu dose única de ivermectina oral (400 µg/Kg). O diagnóstico dos ácaros foi realizado com auxílio de microscópio estereoscópico após a devida coleta de material. Para P. ovis foi realizada através de coleta do cerúmen com auxílio de zaragatoas efetuadas nas orelhas e para por L. gibbus foi realizada coleta de pelos nas regiões do pescoço dorsal, The aim of the study was to evaluate the efficacy of oral ivermectin in the control of Psoroptes ovis and Leporacarus gibbus in naturally infested rabbits. Twenty adult rabbits were selected; they were distributed in two groups with equal proportions of both sexes, containing ten animals per group. In the control group the same volume of the treatment was administered of saline solution, meanwhile the treated group received a single dose of oral ivermectin (400µg/kg). The diagnosis of the mites was made with a stereoscopic microscope, after the proper collection of material. For P. ovis it was performed by collecting of ear wax with swabs and for L. gibbus it was performed by collecting hairs in the dorsal part of the neck, lumbar right, lumbar left, ventral side of the tail and ventral abdomen. The evaluation of the efficiency and the clinical evaluation of the lesions, measured in scores (grade 0 to 4) was made in days 0, +3, +7, +4, +21, +28, and +35, after treatment. An efficiency of 100% was observed for P. ovis following day +7, and for L. gibbus following day +14, remaining negative until the final day of the study. The score of lesions in the ears of the treated group regressed following day +14 and on day +21 all animals reached a score of 0. In the control group, two animals presented an increase in ear lesion score, one rabbit presented an increase from score 1 to 2, and the other rabbit, from score 3 to 4. No adverse reactions were observed in the treated animals. The single dose administration of oral ivermectin was successful in the control of P. ovis and L. gibbus in naturally infested rabbits.

Efficacy of oral doramectin as treatment for Psoroptes ovis and Leporacarus gibbus in naturally infested rabbits

“…Doramectin presented a greater action period when compared to ivermectin (Voyvoda et al 2005), nonetheless the results of its usage do not differ from other reports. Coelho et al (2014) performed a 35 day study evaluating the efficacy of oral ivermectin in the control of Psoroptes ovis and Leporacarus gibbus in naturally infested rabbits. The authors reported 100% for P. ovis in days +7, +21, +28 and +35, with only one positive rabbit on day +14; and 100% efficacy for L. gibbus following day +14.…”

“…Different drugs have been used for the treatment of these ectoparasites with good results, such as ivermectin (Pandey 1989, Stephen et al 1990, Coelho et al 2014, moxidectin (Wagner &Wendlberger 2000), eprinomectin (Pan et al 2006), selamectin (McTier et al 2003, Fisher et al 2007), permethrins (Melo et al 2008), d-phenothrin/pyriproxyfen associations , pyriprole (Batista et al 2013), and phytotherapeutic products (Maske & Kolte 1999, Joshi et al 2000, Fernandes et al 2012, Nong et al 2012, administered topically or systemically.…”

Mange in Rabbits: An Ectoparasitic Disease with a Zoonotic Potential

“…Other species of mites such as Cheyletiella parasitovorax [ 39 ], Notoedres cati cuniculi [ 27 , 44 ], and Psoroptes ovis [ 10 , 11 ] have been also identified in rabbits with skin lesions.…”

“…Moreover, Notoedres cati cuniculi burrowing mite has been detected in rabbits [2,7,8]. However, Psoroptes ovis has been identi ed in rabbits with ear lesions [9][10][11]. In 2017, scabies has been added to the World Health Organization Neglected Tropical Diseases portfolio [12].…”

Eficácia da ivermectina comprimido no tratamento da sarna sarcóptica em cães naturalmente infestados

“…Seu uso em cães e gatos é aprovado para prevenção da dirofilariose (Mueller 2004), mas é muito útil na dermatologia de pequenos animais no tratamento de várias infestações e, no manejo de outras alterações cutâneas relacionadas à ecto e endoparasitos (Paradis 1998). A absorção da ivermectina sistêmica obtém melhor eficá-cia e maior meia vida quando utilizada por via parenteral ou transdérmica (Taylor 2001), sendo a via oral indolor e de maior praticidade, principalmente quando a administração do produto é feita pelo proprietário (Coelho et al 2014). O objetivo do presente estudo foi avaliar a eficácia da ivermectina oral no tratamento de cães naturalmente infestados pela sarna sarcóptica.…”
