Ans : A (W.Bancrofti) Hydrocele (genital involvement) is only feature of Bancroftian filariasis (W.Bancrofti) not of (rarely) Brugian fila riasis( B. malayi& B.Timori)"In chronic Bancroftian filariasis. the main clinical features are hydrocele; elephantiasis & chyluria. The Brugian filariasis isgenerally similar to Bancroftian filariasis, but the genitalia are rarely involved, except in areas where Brugian filariasis occurs together with Bancroftian filariasis"-Park 21st/246"Wuchereria bancroftl can affect the legs, arms, vulva, breasts, and scrotum (causing hydrocele formation), while Brugia timori rarely affects the genitals"-en.wikipedia.org.filariaisis"Genital lesions or chyluria (milky colour urine) do not occur in brugian filariasis. Hydrocele is the most common sign of chronic bancroftian filariasis, followed by lymphoedema, elephantiasis and chyluria-nvbdcp.gov.in"The most common presentations of the lymphatic filariases are asymptomatic (or subclinical) microfilaremia, acute adenolymphangitis (ADL), and chronic lymphatic diseases hydrocele. If lymphatic damage progresses, transient lymphedema can develop into lymphatic obstruction and the permanent changes associated with elephantiasis.
