Wuchereria bancrofti and Brugia malayi pathogenesis Ans -Mostly asymptomatic in early years of infection. Low grade fever may result from immune reaction to developing worms. -Acute phase of infection is when microfilariae are released. Host responds to dying worms and worm byproducts. Lymph nodes become inflamed. Immune cell activation leads to fevers, chills toxemia ... Lymphatic vessels become swollen, damaged and leaky (lymphedema). Get leakage of protein or fluid to surrounding t...
