Which one among the following is the generic name of the causal organism of Elephantiasis ?

Elephantiasis, also known as lymphatic filariasis, is a parasitic disease primarily caused by the thread-like nematode Wuchereria bancrofti [2]. While other species like Brugia malayi and Brugia timori can also cause the condition, Wuchereria bancrofti is responsible for approximately 90% of all cases globally [2]. The organism belongs to the superfamily Filarioidea, commonly referred to as filariae. The life cycle involves the production of microfilariae by adult worms, which are then ingested by mosquito vectors such as Culex, Anopheles, or Aedes during a blood meal [2]. Wuchereria bancrofti is the specific scientific name of the most prevalent causal organism, whereas 'filaria' is a broader group name and 'microfilaria' refers to the larval stage [2]. Culex pipiens is a common mosquito vector but not the causal organism itself [2].
