After this stay abroad his interest was concentrated in "contractile proteins" in flagella and cilia at the Komaba Campus of the University of Tokyo, although he had already described ATPase activity of the flagella isolated from sea urchin spermatozoa in 1958, and in 1968 he discovered "tubulin" as the counterpart of dynein ATPase in
flagellar and ciliary movement.
Antennae 40% longer than head and PN together, 20
flagellar segments, filiform.
Extraction of
flagellar antigen (H): The H antigen was extracted by heating a suspension of S.
Reversible intracellular ATP changes in intact rat spermatozoa and effects on
flagellar sperm movement.
vestitus Beier 1974b from Nepal and Pakistan, possess three
flagellar blades (Beier 1937, 1974b, 1974a; Dashdamirov 2005), the Brazilian species C.
250 and 500 [micro]g/ml, revealed changes of the pear-shaped aspect of the cell (body swollen) and reduction of
flagellar beating frequency in the great part of trophozoites (data not shown).
The starlike,
flagellar transition zone (as seen in cross-section; cf.
If the Enterobacteriaceae Micro-ID system identified an isolate as Salmonella, the isolate was serogrouped with the somatic (O) group agglutination test and serotyped with the Spicer-Edwards
flagellar (H) agglutination test (Bacto-Salmonella Antisera, DIFCO).
Confirming 0157:H7 requires tube titration agglutination of 0157 antisera to the appropriate titer (as indicated by the serum manufacturer) and identification of the H7
flagellar antigen.
Characters shared by this diverse group of organisms are the presence of tubular mitochondrial cristae (Taylor, 1976), tripartite mastigonemes (
flagellar hairs) on the immature flagellum (prymnesiophytes excepted, Bouck, 1972), use of [Beta] -1,3 (or -1,6)-linked glucans as a storage product (Hellebust, 1988) and, in photosynthetic members, chlorophyll a, one or more of the chlorophyll c molecules, and carotenoids (Bjornland and Liaaen-Jensen, 1989; Jeffrey, 1989).
Current knowledge indicates that the toxins, DNAse, hyaluronidase, hemolysin, sialidase, and
flagellar protein seem to play an important role in pathogenicity of C.
This protein may be secreted from the acrosome during the acrosome reaction (24) or be implicated in sperm-egg fusion (26) and it may modulate sperm
flagellar motility (25).
