“…The two large species of freshwater crabs that are consumed by chimpanzees in the Nimba region (Liberonautes latidactylus and L. rubigimanus) are also commonly eaten by humans (Cumberlidge and Huguet, 2003). The former species is a known second intermediate host of Paragonimus uterobilateralis in this part of West Africa (Sachs and Cumberlidge, 1990). The crabs carry an infective stage (metacercaria) of the parasite (Voelker, 1973;Sachs and Voelker, 1982;Monson et al, 1983;Sachs et al, 1986).…”

The significance of aquatic food resources for hominins is poorly understood, despite evidence of consumption as early as 1.95 million years ago (Ma). Here we present the first evidence of a nonhuman ape habitually catching and consuming aquatic crabs. Chimpanzees (Pan troglodytes verus) in the rainforest of the Nimba Mountains (Guinea) consumed freshwater crabs year-round, irrespective of rainfall or ripe fruit availability. Parties of females and offspring fished for crabs more than predicted and for longer durations than adult males. Across months, crab-fishing was negatively correlated with ant-dipping, suggesting a similar nutritional role. These findings contribute to our understanding of aquatic faunivory among hominins. First, aquatic faunivory can occur in closed forests in addition to open wetlands. Second, aquatic fauna could have been a staple part of some hominin diets, rather than merely a fallback food. Third, the habitual consumption of aquatic fauna could have been especially important for females and their immature offspring. In addition to providing small amounts of essential fatty acids, crabs might also be eaten for their micronutrients such as sodium and calcium, especially by females and young individuals who may have limited access to meat.

North American Paragonimiasis (Caused by Paragonimus kellicotti ) in the Context of Global Paragonimiasis

SUMMARY Paragonimus species are highly evolved parasites with a complex life cycle that involves at least three different hosts, i.e., snails, crustaceans, and mammals. The adult forms of Paragonimus species reside and mate in the lungs of a variety of permissive mammalian hosts, including humans. Although human paragonimiasis is uncommonly encountered in North America, both autochthonous and imported disease may be encountered. Paragonimus kellicotti, the species endemic to North America, is a well-known pathogen in wild and domestic animals. Five patients with North American paragonimiasis have been reported in the recent medical literature. The biologic, clinical, radiologic, and laboratory features of paragonimiasis are reviewed, with emphasis on North American paragonimiasis whenever possible.

“…Paragonimus is a highly neglected and poorly known infection acquired through ingestion of undercooked crustacea [ 3 , 4 ], which infects a range of mammals including humans, where symptoms are synonymous with TB infection [ 5 , 6 ]. Diagnostic confusion between TB and paragonimiasis is common in countries such as India [ 6 ] and The Philippines [ 7 ], and has resulted in investment in training and integrated diagnostic procedures for all TB suspects in some areas.…”

Examining human paragonimiasis as a differential diagnosis to tuberculosis in The Gambia

ObjectiveParagonimiasis is a foodborne trematode infection of the lungs caused by Paragonimus spp., presenting clinically with similar symptoms to active tuberculosis (TB). Worldwide, an estimated 20.7 million people are infected with paragonimiasis, but relatively little epidemiological data exists for Africa. Given a recently reported case, we sought to establish whether paragonimiasis should be considered as an important differential diagnosis for human TB in The Gambia, West Africa.ResultsWe developed a novel PCR-based diagnostic test for Paragonimus species known to be found in West Africa, which we used to examine archived TB negative sputum samples from a cross-sectional study of volunteers with tuberculosis-like symptoms from communities in the Western coastal region of The Gambia. Based on a “zero patient” design for detection of rare diseases, 300 anonymised AFB smear negative sputum samples, randomly selected from 25 villages, were screened for active paragonimiasis by molecular detection of Paragonimus spp. DNA. No parasite DNA was found in any of the sputa of our patient group. Despite the recent case report, we found no evidence of active paragonimiasis infection masking as TB in the Western region of The Gambia.Electronic supplementary materialThe online version of this article (10.1186/s13104-018-3134-y) contains supplementary material, which is available to authorized users.
