Efficacy of orally administered fluralaner (BravectoTM) or topically applied imidacloprid/moxidectin (Advocate®) against generalized demodicosis in dogs
TLDR
Single oral administration of Bravecto™ chewable tablets is highly effective against generalized demodicosis, with no mites detectable at 56 and 84 days following treatment, with the exception of one dog in each treated group.
Transmission of Ehrlichia canis by Rhipicephalus sanguineus ticks feeding on dogs and on artificial membranes.
TLDR
Transmission of E. canis by R. sanguineus ticks starts within a few hours after attachment, which is earlier than previously thought and underpin the need for acaricides to provide either a repellent, an anti-attachment and/or a rapid killing effect against ticks in order to decrease the risk of transmission.
Efficacy of sarolaner, a novel oral isoxazoline, against two common mite infestations in dogs: Demodex spp. and Otodectes cynotis.
TLDR
Sarolaner at an oral dose of 2mg/kg was highly effective in reducing the live mite counts associated with a natural infestation of Demodex spp.
Efficacy of afoxolaner in a clinical field study in dogs naturally infested with Sarcoptes scabiei
The acaricidal efficacy of afoxolaner (NexGard®, Merial) was evaluated against Sarcoptes scabiei var. canis in a field efficacy study, when administered orally at a minimum dose of 2.5 mg/kg to dogs…
Prevention of Babesia canis in dogs: efficacy of a fixed combination of permethrin and fipronil (Effitix®) using an experimental transmission blocking model with infected Dermacentor reticulatus ticks
TLDR
The treatment of dogs with Effitix® applied 2 to 28 days prior to infestation with D. reticulatus harboring B.canis, successfully prevented the transmission of canine babesiosis.
Efficacy of slow-release collar formulations of imidacloprid/flumethrin and deltamethrin and of spot-on formulations of fipronil/(s) - methoprene, dinotefuran/pyriproxyfen/permethrin and (s)…
TLDR
The data suggest that the long-term efficacy provided by a medicated collar that is effective, is a means to overcome the fluctuating efficacy of spot-on treatments resulting from a lack of pet owner re-treatment compliance, and consequently protect animals successfully against ectoparasites and probably vector-borne diseases.
Determination of the effective dose of a novel oral formulation of sarolaner (Simparica™) for the treatment and month-long control of fleas and ticks on dogs.
TLDR
Three laboratory studies were conducted to determine the appropriate dose of sarolaner, a novel isoxazoline, for the treatment and month-long control of infestations of fleas and ticks on dogs, and the lowest dose provided 100% efficacy against fleas from treatment through Day 35 and 98.4% at Day 56.
Efficacy of a topical application of Certifect® (fipronil 6.26% w/v, amitraz 7.48% w/v, (S)-methoprene 5.63% w/v) for the treatment of canine generalized demodicosis
TLDR
Both monthly and bi-weekly treatments with Certifect were effective in treating dogs with generalized demodicosis over a 3-month period, and the skin condition of the dogs improved significantly in all groups.
Evaluation of the efficacy of sarolaner (Simparica®) in the prevention of babesiosis in dogs
TLDR
When given 21 or 28 days before tick infestation, a single treatment with sarolaner at the minimum recommended label dose of 2.0 mg per kg body weight prevented the transmission of B. canis by D. reticulatus to dogs.
Efficacy of orally administered powdered aloe juice (Aloe ferox) against ticks on cattle and ticks and fleas on dogs.
TLDR
Treatment was not effective against ticks or fleas on the dogs, and powdered aloe juice in the game maintenance pellets had no effect on the tick burdens of the calves or on the fertility of the ticks.
