Progress in Taxonomy of the Apicomplexan Protozoa

In 1987, 4516 species and 339 genera of the phylum Apicomplexa had been named. They consisted of the gregarines (subclass Gregarinasida) (1624 named species and 231 named genera), the hemogregarines (family Haemogregarinidae) (399 species and 4 genera), the eimeriorins (order Eimeriorida) (1771 species and 43 genera), the hemospororids (order Haemospororida) (444 species and 9 genera), the piroplasmids (order Piroplasmorida) (173 species and 20 genera), and a few others (105 species and 32 genera). The first apicomplexan protozoon was seen by Antony van Leeuwenhoek; in 1674 he saw oocysts of Eimeria stiedai in the gall bladder of a rabbit. The first member of the phylum to be named (by Dufour in 1828) was Gregarina ovata in earwigs. During the quarter century 1826–1850, 41 species and 6 genera of Apicomplexa were named. These numbers increased progressively. In the quarter century 1951–1975, 1873 new species and 83 new genera were named. Data are given for the numbers of named species and genera of apicomplexan protozoa of each group known in 1850, 1875, 1900, 1925, 1950, 1975, and 1987.

FENESTRATE BRYOZOAN GENERA BASED ON SPECIES FROM IRELAND ORIGINALLY DESCRIBED BY FREDERICK M'COY IN 1844

Abstract:  A large number of fenestrate bryozoan species were named in 'A Synopsis of the Characters of the Carboniferous Limestone Fossils of Ireland' by Frederick M'Coy (1844). At the same time, M'Coy named the bryozoan genera Ichthyorachis , Ptylopora and Polypora , each of which by monotypy or by subsequent designation was based on new species within that work. Subsequently, d' Orbigny (1849) named Fenestrellina with the type species Fenestella crassa M'Coy, 1844 as type species; Miller (1961) named Parafenestella with the type species Fenestella formosa M'Coy, 1844 as type species; and Wyse Jackson (1988) named Baculopora with the type species Vincularia megastoma M'Coy, 1844. We re-describe here in more detail than previously the fenestrate type species originally published in M'Coy (1844), provide diagnoses of the genera, and compare the nineteenth century genera with more recently named genera that have been discriminated specifically from them.     

Isolation of some new sulphur bacteria from activated sludge

E mtiazi , G., H abibi , M.H. & S etareh , M. 1990. Isolation of some new sulphur bacteria from activated sludge. Journal of Applied Bacteriology 69 , 864–870.
During studies on bulking of activated sludge some new sulphur micro-organisms, which were able to grow aerobically and anaerobically on reduced sulphur compounds, were isolated on thiosulphate agar. These were capable of autotrophic and heterotrophic growth on a wide range of substrates. In view of their ability to oxidize reduced sulphur compounds, and because one of them was an oxidase- and catalase-positive, Gram-negative, motile coccus (0.36–0.48 μm) it was named Thiosphaera persica . The second one was an oxidase- and catalase-positive, Gram-negative, motile rod (1.32–1.80 μm) and was named Thiobacillus persica . The third one was oxidase-negative, catalase-positive, motile, Gram-negative and polymorphic and was named Sulphobacter polymorpha .

7a-O-methyldeguelol, a modified rotenoid with an open ring-C, from the roots of Derris trifoliata

From the acetone extract of the roots of Derris trifoliata an isoflavonoid derivative, named 7a-O-methyldeguelol, a modified rotenoid with an open ring-C, representing a new sub-class of isoflavonoids (the sub-class is here named as rotenoloid), was isolated and characterised. In addition, the known rotenoids, rotenone, deguelin and alpha-toxicarol, were identified. The structures were determined on the basis of spectroscopic evidence. Rotenone and deguelin were identified as the larvicidal principles of the acetone extract of the roots of Derris trifoliata.     

The Chemical Constituents of Goniothalamus howii (Ⅱ)

Crystal V, VI and VII were isolated from the seeds of Goniothalamus howii Merr. Et Chun. Based on the analysis of IR, 1H-NMR, 13C-NMR, MS and spectral analysis of their derivatives, they were identified as a new type of annonaceous acetogenins—seco-biste-trahydrofuran annonaceous acetogenins. V and VI were named as howiicin D and howiicin E, respectively. VII is a mixture of two compounds, named howiicins F and C, which have the same plane structure.
