Worms and Their Strains

Different strains of Onchocerca volvulus exhibit varying effects on ocular health, particularly in West Africa's savannah regions where higher infection rates correlate with increased blindness. Fascinatingly, the presence of Wolbachia within these strains may influence their impact. Additionally, adult female worms can grow over a foot long, while males travel between nodules to ensure reproduction, highlighting the complex biology of these parasites.
