  Diurnal

  Subperiodic
• a type of periodicity that is active at night

  nocturnal
• a type of periodicity that is active during the day

  diurnal
• a type of periodicity that has no specific time

  subperiodic
• a technique using whole blood that lyses the cells followed by concentrating and examining the sample for microfilariae

  knott technique
• enlargement of the skin and subcutaneous tissue

  elephantiasis
• transient swelling of the subcutaneous tissue

  calabar swelling
• also known as Bancrof's filaria

  the posterior or tail end culminates in a point that is free of nucleus is what distinguish it from other filariae
