13. Th1-like antifilarial immune responses predominate in antigen-negative persons.
To characterize immune responses associated with the putatively immune state in bancroftian filariasis (that is, both microfilaria and antigen free), humoral and cellular responses were compared among antigen- and microfilaria-negative, antigen-positive and microfilaria-negative, and microfilaria-positive individuals. Antifilarial isotype levels were measure

17. Microfilaria malayi in uveitis: case report.
A case of uveitis with microfilariae in the anterior chamber is reported. The organism was recovered from the aqueous and identified as Brugia malayi.

18. Chlamydia trachomatis in hydrocele fluid.
OBJECTIVE: To determine the presence of Chlamydia trachomatis in hydrocele fluid. METHODS: 90 male patients with hydrocele of tunica vaginalis from an endemic area for bancroftian filariasis were investigated for the presence of Chlamydia trachomatis in their hydrocele fluids. C trachomatis antigen detection tests-a direct immunofluorescence assay and an enz

19. Zoonotic Filariasis
Filariae of animals, especially those of mammals, often infect humans and typically produce cryptic infections. These “zoonotic” infections have been reported from virtually all parts of the world including temperate zones. Infections may be symptomatic or not, and the parasites are found in surgical tissue biopsy specimens or, more rarely, are removed i

20. Activation of lymphocytes
The technique involved in studying the activation of lymphocytes in the resting form, and their recognition as dividing and functional cells was studied, using phase contrast and agar as well as fluid culture. Standardization of technical methods was found to be essential, and the effect of variables was studied. Lymphocytes from human umbilical cord vein bl

21. Immune reactions in human filariasis.
Sera from cases of elephantiasis due to Wuchereria bancrofti infection promoted an intense adhesion of peripheral blood leukocytes to W. bancrofti microfilariae in vitro. A similar adhesion was also seen using sera from some normal persons living for several years in areas where filariasis is endemic. No such adhesion was evident with sera from microfilaria

22. Transmission-blocking antibodies recognize microfilarial chitinase in brugian lymphatic filariasis.
Brugia malayi is a parasitic nematode that causes lymphatic filariasis in humans. The monoclonal antibody MF1, which mediates clearance of peripheral microfilaremia in a gerbil infection model, recognizes two stage-specific proteins, p70 and p75, in B. malayi microfilariae. cDNA coding for the MF1 antigen was sequenced, and the predicted protein sequence sho

23. The Immunodominant Brugia malayi Paramyosin as a Marker of Current Infection with Wuchereria bancrofti Adult Worms
The full-length cDNA sequence encoding Brugia malayi L3 paramyosin has been isolated by immunoscreening a cDNA library with a mouse antiserum raised against Wuchereria bancrofti L3 infective larvae. A recombinant truncated form of paramyosin was expressed as a glutathione S-transferase fusion protein and used to evaluate humoral responses of adults from a W.

24. Relation of severe eosinophilia and microfilariasis to chronic African endomyocardial fibrosis.
Over a two-year period, 44 patients had an eosinophil count above the 97th centile. Thirteen of these 44 had heart disease presenting within six months of the onset of symptoms. Microfilariasis was the most likely cause of the raised total eosinophil in these 13 patients. In all, the raised eosinophil count we returned to normal by the use of diethylcarbamaz
