Anthelmintic Effect of Chitosan‐Encapsulated Bromelain on Gastrointestinal Nematodes in Naturally Infected Goats in Kenya

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
The emergence of anthelmintic resistance calls for the development of alternatives, including medicinal plant extracts. The present study was aimed at assessing the efficacy of chitosan‐encapsulated bromelain (EB) as an oral solution drug against GIN in goats.

Antiparasitic Potential of Bioactive Compounds From Punica granatum: Preventive and Therapeutic Effects

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
Diseases caused by parasites are a global public health problem. Due to their heterogeneity and diversity, they can affect various hosts, and some diseases are considered zoonotic. Therapeutic control in parasitic diseases has lost its effectiveness over the last decades.

Assessment of Anthelmintic Resistance in Major Gastrointestinal Nematodes in Sheep and Goat Farms in Mymensingh, Bangladesh

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
Anthelmintic resistance (AR) is a well concern in livestock production. Hence, the study was designed to assess the status of AR in sheep and goat farms at Mymensingh sadar using fecal egg count reduction test (FECRT) and egg hatch assay (EHA). To do this, 10 farms were selected. For FECRT, 40 animals of each farm having more than 200 EPG of feces were
