Migration through host tissues has major costs for parasitic helminths in terms of energy expenditure, risks of attrition and the need to adapt to varying physicochemical environments. Nevertheless, such migratory phases seem to confer a specific survival advantage. One reason for this might be the avoidance of specific host immune-defence mechanisms designed to protect against threats at mucosal surfaces.

Background: (), is a prevalent parasitic worm that infects humans. It is found all over the world, particularly in tropical and subtropical areas. Strongyloidiasis is caused mostly by the parasitic nematode .

Haplorchis taichui is the minute intestinal fluke (MIF), presents a significant public health concern in Thailand. Despite praziquantel (PZQ) being the main treatment, concerns over recurrent use and drug resistance have surfaced. Thus, local herbal alternatives effective against gastrointestinal parasites could be crucial for reducing issues, necessitating exploration of herbal sources for alternative treatments.

Opisthorchis viverrini poses a substantial risk for cholangiocarcinoma (CCA) in Thailand. Despite praziquantel (PZQ) remains the primary treatment for opisthorchiasis, its association with adverse effects and potential CCA development during prolonged treatment, particularly in cases of reinfection and chronic infection, underscores the imperative for alternative herbal interventions with anthelmintic potential. In this context, a prior study suggested the inhibitory effects of Allium sativum L.

Strongyloidiasis is a parasitic nematode infection mainly caused by Strongyloides stercoralis. Immunocompromised conditions, particularly cancer patients treated with chemotherapy and corticosteroids, have a significant risk of developing Strongyloides hyperinfection. The lack of a gold standard laboratory method to rule out this infection and the insensitivity of microscopic stool examination due to low and intermittent larvae output in stool contribute to the low detection rate of this infection.

Background: In infected hosts, immune responses trigger a systemic energy reallocation away from energy storage and growth, to fuel a costly defense program. The exact energy costs of immune defense are however unknown in general. Life history theory predicts that such costs underpin trade-offs between host disease resistance and other fitness related traits, yet this has been seldom assessed.
