ABSTRACT

This work evaluated tick and flea burdens and the efficacy of a single topical application of 10% fipronil + 9% (S)-methoprene spot-on against experimental infestations of Rhipicephalus sanguineus sensu lato and Ctenocephalides felis felis on dogs that were submitted to regular baths for 56-days post-treatment. Four treatments (n = 24) were evaluated: no chemical treatment and no bathing (T01); no chemical treatment + bathing (T02); chemical treatment and no bathing (T03) and chemical treatment + bathing (T04). Dogs were infested with adult ticks and fleas seven days pre-treatment (-7). The ectoparasites were then counted and removed on day -5, followed by a new infestation on day -2 and treatment on day 0. Ticks and fleas were then counted without removal on day 1 and counted with removal on day 2. The dogs were then repeatedly infested with both ectoparasites on days 5, 12, 19, 26, 33, 40, 47 and 54 post-treatment. Baths and ectoparasite counts with removal were performed every 48 h before and after experimental infestation, respectively. Animals of T04 had lower (P ≤ 0.05) tick burden than animals from T01 and T02 from day 2 to day 28. For fleas, the counts varied among days of the study. Dogs from T03 presented lower (P ≤ 0.05) flea burden than dogs from T01 from day 1 until day 56. The same was true for T04 when compared to T01 from day 1 to day 42. Animals of T02 greater (P ≤ 0.05) flea burden than animals of T04 in all dates post treatment. In addition, dogs from T02 presented higher (P ≤ 0.05) flea burden than T01 from day 7 to day 28 and from day 49 to day 56. In sum, the efficacy of the spot-on formulation used declined over the time against both ectoparasites. The efficacy for ticks ranged from 0.0 to 96.5% and 0.0 to 98.52% for T03 and T04, respectively. While for fleas, the efficacy of the formulation ranged from 67.41 to 100% for T03 and 40.18 to 100% for T04. So, bathing dogs that were not treated increased C. f. felis burden but not R. sanguineus s. l. burden. The residual efficacy of the product had a shorter duration against these ectoparasites for dogs that received subsequent bathing.

ABSTRACT

O cervo-do-pantanal (Blastocerus dichotomus) é o maior cervídeo do continente sul-americano e figura na lista de animais ameaçados de extinção. Dentre os principais problemas dessa espécie em ambiente artificial está a puliciose. Essa infestação pode causar anemia expressiva, inapetência e óbito. O controle desses parasitos é realizado de diversas formas, com combate das pulgas nos animais e no ambiente, sendo que o controle conjunto é o mais eficaz. No entanto, o controle das pulgas em cervídeos é bastante restrito, tanto pelo temperamento dos animais, quanto pela inexistência de um produto eficaz e de longa ação. Esse trabalho testou uma coleira à base de imidacloprida e flumetrina, preconizada para uso em cães domésticos, por ser de aplicação única e de longa duração. A coleira se mostrou eficiente por seis meses na eliminação das pulgas, associada à aspersão de deltametrina no recinto; sem ocorrência de efeitos adversos.(AU)


The marsh deer (Blastocerus dichotomus) is the largest deer in the South American continent and is listed in the red list of endangered animals. Among the main problems of this species “ex situ” we have puliciosis. This infestation can cause significant anemia, weariness and even death. The control of these parasites is carried out in several ways, with flea combat in the hosts and in the environment, and joint control is the most effective method. However, the control of fleas in animals is quite restricted, both by the behavior of the animal, and by the nonexistence of an effective and long-acting anti parasitic product. This work tested a collar impregnated with imidacloprid and flumethrin recommended for use in domestic dogs, because it is of single application and long duration. The collar showed to be efficient for six months, in the elimination of fleas, associated with spraying of deltamethrin in the enclosure; without occurrence of adverse effects.(AU)

El control de los parásitos se lleva de varias maneras, con el combate de las pulgas en el huésped y el medio ambiente, en el que el conjunto de control es más eficaz. Sin embargo, el control de pulgas en animales salvajes es muy restringido, por el comportamiento agresivo del animal, como la ausencia de un producto eficaz y de acción prolongada. Este estudio probó un collar impregnado con imidacloprida y flumetrina, com uso recomiendado en perros domésticos, en una sola aplicación y con largo plazo. El producto ha demostrado eficaz durante seis meses en la eliminacion de pulgas, asociado con la pulverizacion de deltametrina en la habitación; sin efectos adversos en los animales salvajes.(AU)

ABSTRACT

As comunidades de felinos que vivem em casas infestadas tornam o controle parasitário particularmente mais difícil do que em cães frente à menor pletora de produtos disponíveis para esta espécie.Este relato avaliou a eficácia de colares de liberação lenta de imidaclopride/flumetrina para tratar felinos altamente infestados de pulgas e para prevenir infestações por 8 meses. Dez felinos receberam coleiras deliberação lenta contendo uma formulação de imidaclopride 10 % /flumetrina 4,5 %, nenhum outro método de controle parasitário foi realizado. A presença de pulgas foi mensurada periodicamente por 8 meses. Dois destes animais apresentavam sintomatologia compatível com alergopatia. No momento do tratamento, todos os felinos apresentavam-se intensamente infestados. Dos animais com sintomatologia dermatológica, os dois animais, apresentaram melhora significativa depois de quatro semanas da aposição da coleira e não voltaram a apresentar pulgas nem lesões dermatológicas por 8 meses (período de duração deste relato). Havia mais de 80 pulgas por felino (após penteados) no início de tratamento, este número foi reduzido a zero após seis semanas e manteve-se em zero parasita após 8 meses de acompanhamento. Com base nas evidências observadas de eficácia e duração, os colares de liberação lenta de imidacloprida/flumetrina podem ser considerados como um meio prático eficaz de controle de pulgas e DAPP em felinos em ambientes fechados infestados.


Feline communities living in infested homes make parasitic control more difficult than in dogs because of the smaller plethora of products available for this species. This report evaluated the efficacy of imidacloprid/flumethrin slow-release collars to treat felines highly infested with fleas and to prevent infestations for 8 months. Ten felines received slow-release collars containing a formulation of 10 % imidacloprid /flumethrin 4.5 %, no other parasitic control method was performed. The presence of fleas was measured periodically for 8 months. Two of these animais presented symptomatology compatible with allergy. At the time of treatment, all cats were intensely infested. Of the animals with dermatological symptomatology, the two animals showed significant improvement after four weeks of application of the collar and did not return to present fleas or dermatological lesions for 8 months (duration of this report). There were more than 80 fleas per feline (after brushing) at the start of treatment, this number was reduced to zero after six weeks and remained at zero parasite after 8 months of follow-up. Based on the observed evidence of efficacy and duration, imidacloprid/flumethrin slow-release collars can be considered as a practical effective means of controlling fleas and FAD in felines in closed environment infested.

ABSTRACT

The study was conducted in order to evaluate the effect of a fipronil/(S)-methoprene formulation against fleas on naturally infested cats. The study involved a population of 89 cats distributed among 24 veterinary practices in 9 regions of Spain. The product was applied according to label instructions on days 0, 30 and 60. Animals underwent parasitological and clinical assessments on day 0 and thereafter in monthly intervals (every 30 days) until day 90. Ctenocephalides felis was the most abundant species (98.9% of all fleas collected), and flea abundance on Day 0 was associated with the hair type, the location of the household, and the time elapsed from the last anti-flea treatment. Fipronil/(S)-methoprene demonstrated high efficacy and induced the reduction of clinical signs related to the presence of fleas. Clinical signs and flea abundance decreased significantly throughout time (P=0.001) with an efficacy rate of 72.6% at Day 30, 88.4% at Day 60 and 93.9% at Day 90. A high level of flea control and a remission of the clinical signs related to presence of fleas were observed on cats following 3 monthly applications a fipronil/(S)-methoprene formulation.(AU)
