Summary
Fish-borne parasitic infections pose risks to pregnant women, causing anemia and altered immunity. Fetal complications include growth restriction and preterm birth, highlighting a critical knowledge gap.
Area of Science:
- Parasitology
- Maternal-Fetal Medicine
- Foodborne Illnesses
Background:
- Intestinal parasitic worms affect over 2 billion globally.
- Increasing popularity of raw fish dishes elevates risk of fish-borne parasitic infections.
- Limited data exists on fish parasites during pregnancy.
Purpose of the Study:
- To review current knowledge on fish-borne parasitic infections in pregnancy.
- To discuss pathophysiology, maternal immune alterations, and fetal effects.
- To identify knowledge gaps and potential treatment considerations.
Main Methods:
- Literature search on PubMed and Web of Science.
- Search terms included "fish parasites," specific parasite genera, and pregnancy-related terms.
- 24 relevant publications were selected for review.
Main Results:
- Fish-borne parasitic infections in pregnant women primarily cause anemia and altered maternal immunity.
- Altered immunity may increase susceptibility to other infections.
- Fetal effects include intrauterine growth restriction and preterm delivery.
Conclusions:
- Fish-borne parasitic infections present significant risks to both maternal health and fetal development.
- Anemia and immune compromise are key maternal impacts.
- Intrauterine growth restriction and preterm birth are primary fetal concerns.

Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
