Ultrasonographic detection of living adult Wuchereria bancrofti using a 3.5-MHz transducer.

Animated documentation of the filaria dance sign (FDS) in bancroftian filariasis

BACKGROUND: Ultrasonography is able to detect adult Wuchereria bancrofti worms in scrotal lymphatic vessels of infected men on account of the characteristic pattern of adult worm movements, known as the filarial dance sign. Furthermore, the technique is able to delineate associated pathology, such as hydrocoele and lymphoedema, which can be diagnosed in early stages. Ultrasonography is also use...

Frequent detection of worm movements in onchocercal nodules by ultrasonography

BACKGROUND: Ultrasonography (USG) is known to be a suitable tool for diagnosis in lymphatic filariasis as the adult filarial nematode Wuchereria bancrofti in scrotal lymphatic vessels of infected men can be detected by the characteristic pattern of movement, the Filaria Dance Sign. In onchocerciasis, moving adult worms have not yet been demonstrated by USG. In addition the verification of drug ...

Preliminary observations on fluids incubated with Wuchereria bancrofti using the immunochromatographic test Observações preliminares de fluidos incubados com Wuchereria bancrofti usando o teste imunocromatográfico

To assess the performance of the immunochromatographic test for filariasis, adult Wuchereria bancrofti worms were incubated under different conditions. The tests were strongly positive with incubation fluids from both living and mechanically damaged females. Negative results were observed with incubation fluids from all male worms and from intact dead females. Key-words: Wuchereria bancrofti. A...

Adult Filarial Worm of Unknown Species Removed from the Skin of a Human Subject

worms under the left conjunctiva of a Jewess who had suffered from elephantiasis for four years. An attempt to obtain the worms for examination failed, one disappearing into the tissues during section and the other being lost in the process of extraction in some unaccountable manner. Several members of the patient's family were infected with Wuchereria bancrofti and the presumption is that thes...
