Successful cryopreservation of Wuchereria bancrofti microfilariae

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1982
A fast freezing technique developed by James (1981) significantly improved the yield of schistosome larvae that could be stored in liquid nitrogen. This was adapted by Ham et al. (1981) to the freezing of microfilariae of Onchocerca spp. with excellent results. They found 70 to 80% of the cryopreserved larvae remained viable using this method and since

Microfilarial periodicity of Wuchereria bancrofti in Vanuatu

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2003
A study on the relationship between the microfilarial periodicity of Wuchereria bancrofti and vector biting activity was carried out in Penama province, Vanuatu from February to April 1999, to enable the design of a more efficient strategy to control filariasis transmission. The microfilarial periodicities of 22 W. bancrofti antigen-positive volunteers

Experimental Transmission of Wuchereria Bancrofti to Monkeys

The American Journal of Tropical Medicine and Hygiene, 1979
Infective larvae of Wuchereria bancrofti from laboratory-raised Culex pipiens fatigans and Aedes togoi mosquitoes fed on human volunteers in Jakarta, Indonesia (J strain) and Kinmen Island, China (K strain) were introduced into Taiwan monkeys (Macaca cyclopis) by subcutaneous inoculation, by foot puncture, or by permitting infected mosquitoes to feed ...

Epidemiology of Wuchereria bancrofti in Leogane, Haiti

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1988
A survey for Wuchereria bancrofti in Leogane, Haiti, revealed that 140 of 421 individuals (33%) had a patent infection, of which 40% lived in the suburban outskirts of the city. The median microfilaria density was 19.1 per 20 mm3 of blood for suburban dwellers compared with only 8.8 for those living in the city. The vector, Culex quinquefasciatus (Say),

Studies on the Vectors of Wuchereria Bancrofti in Liberia

The American Journal of Tropical Medicine and Hygiene, 1955
Summary From January, 1952, through April, 1953, a series of dissections of wild-caught anthropophilic mosquitoes for larval worms resembling Wuchereria bancrofti was performed in Marshall Territory, Liberia. Advanced-stage infections were found in Anopheles gambiae, A. melas, and A. hancocki.

Susceptibility of aposymbiotic Culex quinquefasciatus to Wuchereria bancrofti

Journal of Invertebrate Pathology, 1983
Abstract Larvae of the mosquito Culex quinquefasciatus originating from Kenya were reared in 0.025 mg/ml tetracycline hydrochloride. Some of the resulting progeny were shown, by electron microscopy and crossing experiments, to have been rendered free of the rickettsia like symbiont Wolbachia pipientis and from these progeny, symbiont-free lines were ...

Transplacental Transmission of Wuchereria bancrofti in Haitian Women

The Journal of Parasitology, 1993
To document the occurrence of transplacental transmission of microfilariae and to determine how frequently it occurred, umbilical cord blood samples and placental tissues were collected from 22 microfilaria-positive women in an area with endemic Wuchereria bancrofti. Microfilaria (mf) counts in the women ranged from 1 to 3,820 mf/ml. Microfilariae were

Lymphatic pathology in Wuchereria bancrofti microfilaraemic infections

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1995
To determine the extent of lymphatic disease in persons infected with Wuchereria bancrofti who were microfilaraemic, we examined the superficial lymphatics of the legs by scintigraphy. In 4 endemic control subjects and in 10 of 14 clinically asymptomatic microfilaraemic individuals, lymphoscintigraphy revealed one major channel of lymphatic drainage in

Ultrastructural characterization of intracellular bacteria of Wuchereria bancrofti

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2001
Ultrastructural observations on the structure and distribution of endosymbiotic bacteria within the tissues of Wuchereria bancrofti are described. In female worms the organisms were observed in the lateral cords of the hypodermis, oocytes, developing eggs and in intrauterine microfilariae.

Microfilaria of Wuchereria Bancrofti in Bone Marrow Smear

The American Journal of Tropical Medicine and Hygiene, 1976
Microfilariae of Wuchereria bancrofti were detected in seven cases of anemia in persons with asymptomatic filariasis. In three cases microfilariae could not be detected in the blood. Their presence in bone marrow may indicate the ability of microfilariae to cross the vessel wall.
