摘要:

SUMMARYThe existence of CARRIERS of the pathogenic agents of tinea capitis is discussed, their number and importance in epidemiology are emphasized.The use of Woodlight is advocated in detecting the carriers, in establishing the extent of the infection of the scalp, in the control of the progress and efficiency of treatment and in the final determination of a cure.For the demonstration of fungi on direct microscopic examination the general use of chlorallactophenol formulas are recommended.The taxonomic individuality ofAchorion gypseumBodin, 1907, is upheld in refutation of certain tendencies to make this species synonymous withMicrosporum fulvunmUriburu, Sabouraud, 1910.Finally, the availability of Woodlight for the purpose of identification of fungus growth in giant cultures is taken under scrutiny. The unwarranted statement of Livingood and Pillsbury about the extreme usefulness of this physical agent in identification of fungus species is refuted by the experience of other research workers and by the own experiments of the writer.

摘要:

SUMMARYFive monosporangiate species ofRozella, R. laevisinPythiumsp.,R. CladochytriiinCladochytrim replicatimi, R. RhizophlyctiiinRhizophlyctis roseaandRhizophlyctissp.,R. EndochytriiinEndochytrium operculatum, andR. RhizophydiiinRhizophydium globosum, were found in Brazil.Rozella Rhizophydiihas fairly large zoöspores and is limited in host range toRhizophydium globosum.It is accordingly diagnosed as a new species, although its life cycle is not completely known. In addition to these monosporangiate parasites, one polysporangiate species,R. Achlyae, was found in the sporangia ofAchlya flagellata.

摘要:

SUMMARY(1)Zoösporogenesis in resistant sporangia is not normally initiated until the resistant sporangia have been dried and/or placed in fresh water or nutrient solution.(2)Thenumberof R. S. zoöspores per resistant sporangium is approximately 4 times as great as the number of female gametes produced in the female gametangium, a structure of approximately the same volume.(3)Thevolumeof R. S. zoöspores at cleavage is approximately one-fourth as great as the volume of female gametes at cleavage.(4)Thevolumeof R. S. zoöspores at cleavage is approximately one-fourth as great as their volume when swarming.
