(warble fly) grubs cause myiasis in goats, in mountainous and semi-mountainous areas and different regions in Pakistan, and cause substantial losses to livestock. The palpation method for detecting warble flies generally neglects the infestation intensity; therefore, the development of a reliable and efficient diagnostic technique is extremely necessary. This study compared three indirect enzyme-linked immunosorbent assay (ELISA) methods for detecting anti- antibodies using the hypodermin C (HyC) purified from Hypoderma spp.

Schistosomiasis japonica is a zoonotic parasitic disease causing liver fibrosis. Liver sinusoidal endothelial cells (LSECs) exhibit fenestrations, which promote hepatocyte regeneration and reverses the process of liver fibrosis. To investigate the pathological changes of LSECs in schistosomiasis, we established a Schistosomiasis model.

  • Ticks are ectoparasites that transmit pathogens threatening both animal and human health, particularly in hot and humid regions of Pakistan.
  • A study identified 11 tick species across various livestock and animals, discovering an overall tick prevalence of 14.3% among the 2,846 animals examined, with significant variation by host type and agro-ecological zone.
  • The highest tick infestation rates were observed in camels and donkeys, with specific zones exhibiting notably high infestation rates, highlighting the need for awareness of tick-borne diseases affecting both animals and humans.

A wide range of novelties and significant developments in the field of veterinary science to treat helminth parasites by using natural plant products have been assessed in recent years. To the best of our knowledge, to date, there has not been such a comprehensive review of 19 years of articles on the anthelmintic potential of plants against various types of helminths in different parts of the world. Therefore, the present study reviews the available information on a large number of medicinal plants and their pharmacological effects, which may facilitate the development of an effective management strategy against helminth parasites.
