E-mail: vetjulio@ yahoo.com.br Due the fact that considered docile, small and easy to handle, domestic rabbits have been bred as pets. Skin diseases caused by parasitic agents are common. Sometimes asymptomatic, infestation by mites species Psoroptes ovis can cause inflammation of the ear canal, ear drooping, crusting and pruritus. The goal of the study was to evaluate the efficacy of pyrethroid flumethrin applied directly into the auditory canal for treatment of P. ovis in naturally infested rabbits. 12 rabbits divided into two groups were used: Group 1, control group and group 2, treated with 1% flumethrin (1mg/kg) as a single dose. The clinical and parasitological evaluations of the animals were performed on days 0, +3, +7, +14, +21, +28 and +35 after treatment. The effectiveness of P. ovis was 83.33% at day +3; +21; +28 and +35, for 100% only on days +7 and +14. All rabbits in the treated group showed high clinical, except an animal that had four score on day 0. In the control group, all animals showed an increase in the score and worsening of symptoms. The flumethrin 1% pour-on at a dosage of 1 mg / kg administered directly into the ear canal was effective in controlling P. ovis in naturally infested rabbits without causing no adverse reactions in treated animals
Eficácia da ivermectina oral no controle de Psoroptes ovis e Leporacarus gibbus em coelhos naturalmente infestados
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
Efficacy of oral doramectin as treatment for Psoroptes ovis and Leporacarus gibbus in naturally infested rabbits
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
New horizons for fundamental physics with LISA
International audienceThe Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitational interaction is both strong and dynamical. In this white paper, the Fundamental Physics Working Group of the LISA Consortium summarizes the current topics in fundamental physics where LISA observations of gravitational waves can be expected to provide key input. We provide the briefest of reviews to then delineate avenues for future research directions and to discuss connections between this working group, other working groups and the consortium work package teams. These connections must be developed for LISA to live up to its science potential in these areas
