Growth 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 کاملAXENIC CULTURE AND CRYOPRESERVATION OF GIARDIA LAMBLIA ISOLATED IN IRAN
Giardia lamblia cysts were isolated from fecal samples of 55 symptomatic and asymptomatic patients with giardiasis. The cysts were harvested and purified using the sucrose gradient method. IS The excystation of G. lamblia was obtained by treating them with HCI (0.01N)', then they were transferred on to modified TYI-S-33 medium. Out of 55 stool samples 17 cases were excysted with a rate of ...
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 کاملTriassic origin and early radiation of multicellular volvocine algae.
Evolutionary transitions in individuality (ETIs) underlie the watershed events in the history of life on Earth, including the origins of cells, eukaryotes, plants, animals, and fungi. Each of these events constitutes an increase in the level of complexity, as groups of individuals become individuals in their own right. Among the best-studied ETIs is the origin of multicellularity in the green a...
متن کاملComplete developmental cycle of Leishmania mexicana in axenic culture.
A complete developmental sequence of Leishmania mexicana has been produced in axenic culture for the first time. This was achieved by manipulation of media, pH and temperature conditions over a period of 16 days. All experiments were initiated with lesion amastigotes that were transformed to multiplicative promastigotes by culture in HOMEM, 10% foetal calf serum, pH 7.5, at 25 degrees C. Metacy...
