5 mg/kg (0.23 mg/lb) against natural infections of A. braziliense in dogs. We hypothesized that milbemycin oxime would be over 90% efficacious when administered as a single treatment. Naturally infected dogs from South Africa were used as A. braziliense is known to be endemic to this area ( Verster, 1979, Minnaar and Krecek, 2001 and Minnaar et al., 2002). The study design was based INCB018424 mouse on the known life-cycle of A. braziliense and is routinely used to determine the efficacy of anthelmintics in well controlled laboratory

settings. Thirty-six clinically healthy dogs (other than intestinal parasitism) of various breeds and body weights that were a minimum of 10 weeks of age were used and were representative of the general dog population present in South Africa. Statistically, both of the milbemycin oxime treatment groups had significantly (p < 0.0001) fewer A. braziliense isolated at necropsy when compared to the placebo control group with reductions ranging from 94.91% (Sentinel) to 98.02% (Interceptor) from a single administration. Taken together,

these results confirm that all requirements for an adequate test of efficacy were met in this study. No adverse events were reported nor were there any significant reductions in body weight observed indicating milbemycin oxime in these formulations was well tolerated, which is consistent with previous studies that have shown milbemycin oxime is safe when administered orally for control of nematode parasites (Ide et al., 1993). This study demonstrates Selleck Anti-diabetic Compound Library milbemycin oxime, when administered in the commercial formulations of Interceptor® Flavor Tabs® and Sentinel® Flavor Tabs® at a minimum milbemycin oxime dose of 0.5 mg/kg (0.23 mg/lb), is efficacious for the removal and control Thymidine kinase of adult A. braziliense in dogs.

“Fasciola hepatica is a helminth parasite of the bile ducts of various vertebrate hosts, including humans, and is currently considered as an emerging zoonosis ( Mas-Coma et al., 2005). This helminth has a worldwide

distribution and is considered the most important trematode parasite of domestic ruminants, as it is responsible for significant economic losses of cattle and sheep herds. The losses due to parasitism in these animals are attributed primarily to the loss of livers in abattoirs, secondary bacterial infections, loss of production, delayed animal growth, costly anthelminthic treatment and losses due to animal morbidity and mortality ( Bostelmann et al., 2000). The infection persistence and weather conditions may influence parasite epidemiology. Since a natural infection can last for prolonged periods especially in cattle, moving infected animals to unaffected regions associated to favorable environmental conditions may contribute to the emergence of new areas of occurrence of fasciolosis ( Lima et al., 2009).
