In Capillaria pterophylli Heinze, 1933, two lateral bacillary bands extend along the whole body in female and male worms. A ventral bacillary band is present in females only. The bacillary bands consist of glandular and non-glandular cells, and in the region between the nerve ring and the end of the sticliosome, ciliated sense receptors in tight connection with gland cells are present.
The short-time scale spectroscopic variability of some Be stars has been mvestigated with an optical fiber spectrograph and a CCD camera. We have found on time-scale of hours and days: -1) weak changes in the Hα emission line profile of yCas; -2) changes in the structure and the intensity of the Hα emission line core and sometimes in the wings of the Hel λ 6678 of φPer; -3) no table variations in the Hel photospheric line profile λ 6678 and in the core of the Hα absorption line of o And, which do not seem correlated with the photometric period 1.57 days given by Harmanec (1984).
This is a followup report on the viability of pathogenic Acanthamoeba castellami, Naegleria australiensis, and N. fowleri during 5 years of cryopreservation and the virulence of N. fowleri during 30 months of cryostorage, all at -70’C. The greatest decrease in viability occurred during the first year of freezing and was 10-fold greater than the average yearly decrease during years 2-5. At 5 years of cryostorage, viability was 33 % for A. castellana, 38 % for N. fowleri and 51% for N. australiensis. Virulence of N. fowleri did not decrease during 30 months of freezing and what appeared to be an increase in virulence during cryopreservation may be the result of reduced viability of the less virulent amebae in a culture.
