Introduction

Ectoparasites are organisms that live on the skin or external surface of a host, relying on the host for sustenance, maturation, and reproduction. Common ectoparasites include ticks, lice, mites, fleas, and bed bugs. These parasites are widespread and affect a variety of hosts, including humans, livestock, and wildlife [1, 2, 3, 4].

Biology and Behavior Ectoparasites are arthropods that have evolved sophisticated mechanisms to locate, attach to, and feed on their hosts. They may be permanent residents on the host or visit intermittently. Their feeding behavior often involves blood-sucking, which causes direct harm to the host’s skin and underlying tissues. This can lead to irritation, inflammation, blood loss, and secondary infections [5, 6, 7].

Impact on Livestock and Humans In livestock, ectoparasitic infestations pose a significant threat to economic productivity. They cause mechanical damage, anemia, loss of condition, allergic reactions, toxicosis, and sometimes mortality. Ticks, in particular, are notorious for transmitting serious diseases such as babesiosis, theileriosis, and anaplasmosis. Other ectoparasites like lice and mites cause dermatitis, intense itching, and skin lesions that can lead to further complications. Humans are also affected by ectoparasites such as lice, scabies mites, ticks, and fleas. These parasites not only cause discomfort and social stigma but also serve as vectors for infectious diseases including typhus, Lyme disease, plague, and scabies-related complications. Humans have evolved defense mechanisms against ectoparasites, including sensory detection, itch responses, and grooming behaviors to reduce infestation. Epidemiology and Control The prevalence of ectoparasites varies by region, climate, and host species. For example, ticks are particularly prevalent in parts of Pakistan due to favorable climatic conditions and insufficient control measures. Control of ectoparasites is challenging as they are difficult to eradicate permanently and require ongoing management strategies. These include chemical treatments, biological control methods, and improved veterinary and public health practices. Future Directions Research continues to focus on understanding the epidemiology of ectoparasites, their role in disease transmission, and developing effective control strategies. Collaboration between veterinary and medical fields is essential to mitigate the impact of ectoparasites on animal productivity and human health. Alternative management approaches and further studies are needed to enhance control and prevention efforts globally [8, 9, 10].

Conclusion

Ectoparasites are a major concern for both veterinary and human medicine due to their direct harmful effects and their role as vectors of infectious diseases. Effective management requires a comprehensive understanding of their biology, host interactions, and epidemiology to reduce their burden on health and economy.
