Schistosomiasis models with two migrating human groups

Human schistosomiasis.

Schistosomiasis or bilharzia is a tropical disease caused by worms of the genus Schistosoma. The transmission cycle requires contamination of surface water by excreta, specific freshwater snails as intermediate hosts, and human water contact. The main disease-causing species are S haematobium, S mansoni, and S japonicum. According to WHO, 200 million people are infected worldwide, leading to th...

Force generation by groups of migrating bacteria.

From colony formation in bacteria to wound healing and embryonic development in multicellular organisms, groups of living cells must often move collectively. Although considerable study has probed the biophysical mechanisms of how eukaryotic cells generate forces during migration, little such study has been devoted to bacteria, in particular with regard to the question of how bacteria generate ...

Human Schistosomiasis

Failure is the word that best describes human effort to master schistosomiasis. In 1000 B.C. schistosomes infected man, proof being recovery of calcified ova from dated Egyptian mummies. Earlier by a thousand years, vesical schistosomiasis was prevalent, to judge from references to hematuria by the local medical profession. By A.D. 1969 the world incidence of schistosomiasis was at least 150 mi...
