The cutaneous hypersensitivity reaction in sheep infected with Dictyocaulus filaria was investigated. The saline extract of the worms increased the cutaneous capillary permeability in both the infected and uninfected control animals. Similar increase in the permeability was also observed in uninfected healthy rabbits. The results suggest that the vascular permeability increasing action of the w...
One hypothesis for the decreased rates of atopy observed among helminth-infected individuals is that parasite-induced polyclonal immunoglobulin E (IgE) out-competes allergen-specific IgE for FcepsilonRI binding on basophils and mast cells. In experiments with fresh blood drawn from filaria-infected patients, we found no association between ratios of polyclonal to Brugia malayi antigen (BmAg)-sp...
The distribution of mansonelliases and their relation to various quantitative criteria were determined through the study of 1,057 subjects in 17 localities in ten regions of Amazonas State and Bolívar State. The total prevalence among the blood samples, determined through the Knott technique, was 18.54%. 11.26% were parasited by Mansonella perstans, 9.93% by Mansonella ozzardi, and 2.63% by bot...
Although Japanese parasitologists and physicians have published many papers on the epidemiology, clinical signs and symptoms, treatment, and control of filariasis, they also conducted basic research on filaria or filariasis using materials obtained from patients and animal models. This basic research includes morphology, immunology, physiology and pharmacology. Recently, most papers are written...
common clinical manifestations like acute adenolymphangitis and chronic lymphoedema. But a number of other occult manifestations like asthmatic bronchitis, pulmonary eosinophilia, recurrent URI, pneumonia, pain in abdomen and mono-arthritis of filarial origin in filarial endemic areas remain undiagnosed because of lack of suitable diagnostic tool1. The present study has identified Sd30 (Sd—Seta...
collected from infected houses in Georgetown, British Guiana, to the number of 1,500. Of these, 237 were Stegomyia fasciata, 105 Cellia argyrostris and 1,131 Culex fatigans. Only one Stegomyia was infected, while 7.4 per cent, of all Culex fatigans were found to be infected. No other mosquito was infected, so that it appears that Culex fatigans is the only carrier of Filaria bancrofti of import...
