Parasites in ancient Egypt and Nubia: Malaria, schistosomiasis and the pharaohs
This study explores how their location along the River Nile, agricultural practices, the climate, endemic insects and aquatic snails impacted the type of parasites that were most successful in their populations. A meta-analysis approach finds that up to 65% of mummies were positive for schistosomiasis, 40% for headlice, 22% for falciparum malaria, and 10% for visceral leishmaniasis. Such a disease burden must have had major consequences upon the physical stamina and productivity of a large proportion of the workforce. In contrast, the virtual absence of evidence for whipworm and roundworm (so common in adjacent civilizatio...

Getting around the roundworms: Identifying knowledge gaps and research priorities for the ascarids
Adv Parasitol. 2024;123:51-123. doi: 10.1016/bs.apar.2023.12.002. Epub 2024 Feb 20.ABSTRACTThe ascarids are a large group of parasitic nematodes that infect a wide range of animal species. In humans, they cause neglected diseases of poverty; many animal parasites also cause zoonotic infections in people. Control measures include hygiene and anthelmintic treatments, but they are not always appropriate or effective and this creates a continuing need to search for better ways to reduce the human, welfare and economic costs of these infections. To this end, Le Studium Institute of Advanced Studies organized a two-day conferenc...

Human dirofilariasis - Unforeseen lesion in subcutaneous nodules: Case series from a tertiary care hospital, Wayanad
Indian J Pathol Microbiol. 2024 Jan-Mar;67(1):204-206. doi: 10.4103/ijpm.ijpm_1051_21.ABSTRACTHuman dirofilariasis is a type of zoonotic infection caused by the Dirofilarial species. It is a type of roundworm which is commonly seen in dogs, cats and is transmitted to humans by mosquito bite. Microfilaria is rarely produced in humans. Although clinically they can have varied presentations, it usually presents as ocular or subcutaneous nodules. Definitive diagnosis requires histopathological findings of this worm. We hereby report three cases of Dirofilariasis from a tertiary care hospital in Wayanad.PMID:38358223 | DOI:10.4...

Host gastric corpus microenvironment facilitates < i > Ascaris suum < /i > larval hatching and infection in a murine model
by Yifan Wu, Grace Adeniyi-Ipadeola, Mahliyah Adkins-Threats, Matthew Seasock, Charlie Suarez-Reyes, Ricardo Fujiwara, Maria Elena Bottazzi, Lizhen Song, Jason C. Mills, Jill E. Weatherhead
Ascariasis (roundworm) is the most common parasitic helminth infection globally and can lead to significant morbidity in children including chronic lung disease. Children become infected withAscaris spp. via oral ingestion of eggs. It has long been assumed thatAscaris egg hatching and larval translocation across the gastrointestinal mucosa to initiate infection occurs in the small intestine. Here, we show thatA.suum larvae hatched in t...

Parasitic nematodes: dietary habits and their implications
Trends Parasitol. 2024 Jan 22:S1471-4922(23)00318-5. doi: 10.1016/j.pt.2023.12.013. Online ahead of print.ABSTRACTNematodes, a diverse group of roundworms, exhibit a wide range of dietary habits, including parasitism of animals and plants. These parasites cause substantial economic losses in agriculture and pose significant health challenges to humans and animals. This review explores the unique adaptations of parasitic nematodes, emphasizing their nutritional requirements and metabolic dependencies. Recent research has identified cross-kingdom compartmentalization of vitamin B5 biosynthesis in some parasitic nematodes, sh...

Hepatic pseudotumor associated with < em > Strongyloides < /em > infection: A case report
CONCLUSION: This case highlights the importance of considering parasitic infections, such as Strongyloides, in the differential diagnosis of hepatic masses. Early recognition and appropriate treatment can lead to a favorable outcome and prevent unnecessary invasive procedures. Increased awareness among clinicians is crucial to ensure the timely diagnosis and management of such cases.PMID:38223414 | PMC:PMC10784808 | DOI:10.4254/wjh.v15.i12.1338 (Source: World Journal of Hepatology)
