Surface antigens of Leishmania donovani promastigotes
Surface antigen profiles of Leishmania donovani promastigote isolates have been studied. Surface patterns of Brazilian and African isolates display remarkable similarities and are extremely simple, consisting of three major peptides of 65,000, 25,000, and 23,000 mol wt. Surface iodination and biosynthetic labeling coupled to immunoprecipitation techniques revealed that a single major determinan...

متن کاملGrowth of Pneumocystis Carinii in Axenic Culture
SUMMARY In this research, which was done for two years, we investigated various liquid and solid media without feeder ceells, for the ability to support growth of P. carinii. Data obtained from counting the organisms nuclei showed that, addition of Cycloheximide, penicillin, & streptomycin to neopeptoneN-Acetyle Glucoseamine (N.P.G. medium) can provides growth requirements of organism in its...
متن کاملDictyostelium discoideum during Growth in Axenic Culture
1. The specific activities of fl-N-acetylglucosaminidase, acid phosphatase, ac-mannosidase, P-glucosidase, UDP-glucose pyrophosphorylase and alkaline phosphatase have been determined in myxamoebae of the cellular slime mould Dictyostelium discoideum Ax-2 grown on different media and in different phases of the growth cycle. 2. Variations in enzymic composition occur with changes in growth medium...
متن کاملMetabolic Variation during Development in Culture of Leishmania donovani Promastigotes
The genome sequencing of several Leishmania species has provided immense amounts of data and allowed the prediction of the metabolic pathways potentially operating. Subsequent genetic and proteomic studies have identified stage-specific proteins and putative virulence factors but many aspects of the metabolic adaptations of Leishmania remain to be elucidated. In this study, we have used an unta...
