Abstract
The cheyletid mites that parasitize mammals have been neglected for a long time in Brazil, although they can be common on pets and cause injury to their hosts. Recently, Cheyletiella parasitivorax was found parasitizing a rabbit in Brazil which represents a new host and distribution record for the mite species. An illustrated dichotomous key for the identification of the species in this genus and data from the literature are provided.

Therapeutic use of Bacillus thuringiensis in the treatment of psoroptic mange in naturally infested New Zealand rabbits. Vet Parasitol 2017; 238:24-29. [PMID: 28342673 DOI: 10.1016/j.vetpar.2017.03.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2016] [Revised: 03/07/2017] [Accepted: 03/08/2017] [Indexed: 10/20/2022]
Abstract
Bacillus thuringiensis is a bacteria known for its bioinsecticidal toxins and it has been proposed as an alternative in the treatment of several parasites that infect domestic animals (helminths, ticks, mites). In this work, we evaluated the clinical efficiency of the Bacillus thuringiensis GP532 strain in the treatment of six rabbits naturally infested with the P. cuniculi mite. GP532 extract (10mg/ml) was applied by aspersion in both pinna, with a second application after seven days, and the therapeutic effect was measured in both qualitative and quantitative manner. GP532 application resulted in a decreased infestation rate, which was observed as early as 3days post-treatment. At day 14, a decrease from 4.66±0.61 to 0.50±0.10 in the left pinna and from 1.66±0.21 to 0.66±0.16 (P<0.05) in the right pinna was observed. This response was comparable to the commercial drug Ivermectin, which induced a decreased infestation rate from 4.00±0.51 to 0.16±0.10 in the left pinna and from 4.66±0.80 to 0.25±0.11 in the right pinna (P<0.05). At day 30 post-treatment, GP532 decreased the total infested area by 76.80±16.06%, whereas Ivermectin resulted in a 97.41±0.99% decrease. Neither treatment produced irritation or macroscopic lesions. Our results show that the B. thuringiensis GP532 strain has a therapeutic potential in the treatment of psoroptic mange in rabbits.

Efficacy of oral doramectin as treatment for Psoroptes ovis and Leporacarus gibbus in naturally infested rabbits. PESQUISA VETERINÁRIA BRASILEIRA 2017.

Abstract
ABSTRACT: The present study evaluated the efficacy of a single oral dose of doramectin in the control of Psoroptes ovis and Leporacarus gibbus in naturally infested rabbits. Sixteen adult rabbits were selected and distributed in two experimental groups. The treated group received 200 μg/Kg of oral doramectin and the control group received the same volume of saline solution. The diagnosis of the mites was made with a stereoscopic microscope. Hairs from the dorsal part of the neck, lumbar right, lumbar left, ventral side of the tail and ventral abdomen were evaluated for L. gibbus, and ear wax evaluated for P. ovis. The evaluation of the efficiency and the clinical assessment of the lesions was made in days 0, +3, +7, +14, +21, +28, and +35 after treatment. An efficacy of 75% and 87,5% was observed for L. gibbus in days +3 and +7 after treatment, an efficacy of 100% was observed in days +14, + 21, +28 e +35. An efficacy of 100% for the control of P. ovis was observed following day +7. The clinical lesion score of the control group remained unaltered, except for one animal which conditions worsened during experimentation. In the treated group animals, regression of the lesions was observed following day +3, and on day +21 no signal of infestation by P. ovis was present. None of the animals from the treated group presented secondary collateral effects caused by the doramectin, which proved itself as an optimal alternative for mite control in naturally infested rabbits.

Abstract
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, lombar direita, lombar esquerda, cauda ventral e abdômen ventral. A avaliação da eficácia e a avaliação clínica das lesões, mensuradas em escores (grau 0 a 4) foi realizada nos dias 0, +3, +7, +14, +21, +28 e + 35, após o tratamento. Foi observada a eficácia de 100% no controle de P. ovis a partir do dia +7 e para L. gibbus a partir do dia +14, mantendo-se negativos até o final do período experimental. O escore da lesão das orelhas do grupo tratado regrediu a partir do dia +14 e no dia +21 todos os animais atingiram grau 0. No grupo controle, dois animais apresentaram aumento no escore da lesão das orelhas, um coelho apresentou aumento do escore de grau 1 para 2 e outro coelho de grau 3 para 4. Não foram observadas quaisquer reações adversas nos animais tratados. A ivermectina administrada por via oral em dose única foi eficaz no controle de P. ovis e L. gibbus em coelhos naturalmente infestados.
