Definitions
- the present invention relates to an endoparasite control agent containing a carboxamide derivative or a salt thereof as an active ingredient, and an endoparasite control method characterized by administering the control agent orally or parenterally.
- parasitic diseases are caused by parasitic infection of parasites, that is, unicellular protozoa (protozoa), multicellular helminths, arthropods, etc. in animal hosts.
- parasitic diseases are said to have decreased significantly in developed countries due to improvements in environmental sanitation, but from a global standpoint, they are widespread and particularly devastating in developing countries.
- infection sources may be transferred by long / short-term travelers to these foreign countries, as well as infection from intake of imported food, frozen food, raw meat, fish meat, etc.
- Parasitic diseases such as infections are beginning to show a new increasing trend.
- opportunistic infections that cause immunodeficiency due to large doses of immunosuppressants, anticancer agents, AIDS infection, etc., and parasites that have been non-pathogenic or low-pathogenic in the past acquire pathogenicity, have become a problem. Yes.
- Parasitic disease is a universal and serious economic problem in domestic animals such as pigs, horses, cattle, sheep, dogs, cats and poultry.
- parasite infection causes infected animals to cause anemia, malnutrition, weakness, weight loss, serious damage to the intestinal wall and tissues, and organs, contributing to reduced feed efficiency and productivity. Loss is large. Therefore, there has always been a demand for endoparasite control agents such as novel anthelmintic agents or antiprotozoal agents.
