[Development of resistance to antiparasitic agents in parasites pathogenic to animals].

The article discusses the growing concern with the development of drug resistance in parasites that are harmful to various animals, with a focus on the situation in Germany. The study covers the development, prevalence, and management of drug resistance.

Overview of the Research

• This research paper focuses on the rapidly escalating global problem of drug resistance in parasites causing diseases in animals. The authors pay special attention to the situation in Germany.
• The context of this study is vital for animal breeders and veterinarians, as it directly affects animal health, productivity, welfare, and consequently, economic productivity in livestock industries.

Drug Resistance in Parasites

• The authors note that extensive information is available regarding drug resistance development in two particular types of parasites: chicken coccidia and strongyles in horses, sheep, goats, and pigs.
• The birth and growth of drug-resistant strains of these parasites pose pressing challenges for the maintenance of animal health and welfare.

Development of Drug Resistance

• The study discusses how drug resistance develops, recognizing the role of genetic mutations that allow certain parasites to withstand drug treatments, and the subsequent survival and propagative advantage these parasites get in medicated hosts, leading to a propagation of drug-resistant parasite populations.

Incidence of Drug Resistance

• The paper provides a review of the current incidence of drug resistance globally, with a more detailed focus on the situation in Germany.
• The authors emphasize that the problem is increasingly significant and widespread, affecting a wide range of animal species and a variety of parasitic infections.

Management of Drug Resistance

• This section probes strategies to manage the issue of drug resistance. Some approaches can include adopting better dosing techniques, rotating different classes of drugs, and non-drug methods such as implementing sound biosecurity practices to minimize parasite exposure and spread.
• The authors propose the development of newer, more effective drugs and treatment protocols to combat resistant strains as another potential solution, but also recognizes that this could also potentially spur a vicious cycle of drug resistance over time.
