Abstract

Cutaneous larva migrans (CLM) is caused by animal hookworm larvae in man. The conventional diagnosis and treatment of CLM will injure the skin of the patients, and the results are not satisfying. Therefore it should be necessary to do the serological test to diagnose CLM.The antigens were prepared by extracting the hookworm larvae in CTAB detergent, and injected into Balb/C mice. Characterization of antigens were done, quantitatively (by spectrophotonieter) and qualitatively (by SDS PAGE electrophoresis).The results showed that the titre rate of hookworm larvae antigens was 145 ug/ml. The antigens consist of 4 protein fractions with molecular weight of 25 KD, 55 KD, 66 KD and above 66 KD. Those antigents apparently generated high immune response in immunized miceKey Words; Ancylostoma spp. - CTAB detergent - SDS PAGE electrophoresis - immunology - parasitology

Abstract

Background: The circulating antigen of filariasis malayi patient is the excretory/secretory (ES) protein. It was used as antigen in monoclonal antibody production. The ES protein can be obtained by in vitro culture of filarial worm Brugia malayi.Objective : The aims of this research was to evaluate in vitro culture media with glucose supplementation of adults B.malayi to obtain the ES protein maximally.Methods: Adult males and females B.malayi were cultivated in vitro in medium with glucose supplementation in different concentrations (1%, 3% and 5%). The culture media were changed daily and analysis of its protein were carried out quantitatively using Bradford method, and gel electrophoresis (SDS PAGE) for qualitative protein analysis. The cuticle of adults B.malayi were extracted by detergent cetyltrimethyl ammonium bromide (CTAB).Results: The effective culture medium was RPMI with 1% glucose supplementation to produce ES protein maximally, and longevity of worms could survive for 6 days. The quantitative protein concentration of female worms culture medium was 0.2-1.85 ug/ml, and the protein molecular weight of female worms cuticle was 26 kDa- 116 kDa. The protein concentration of male culture medium was 0.2-0.5 ug/ml, the molecular weight of adult male cuticle protein was 34 kDa- 56kDa. The peak concentration of protein in both cultivation was observed on the third day.Conclusion: The best medium for in vitro cultivation of adults B.malayi was RPMI with 1% glucose supplementation. The protein concentration of the female culture media was higher than male .Key words: glucose supplementaion - in vitro culture - filarial worms -Brugia malayi - ES protein
