Three isolates of non-flagellate Pseudomonas aeruginosa obtained from pathological material of human cases are described. Two were found in urinary tract infections and the third in a respiratory infection. They were shown by typing methods to be distinct strains.

A recent phylogenomic investigation shows that the enigmatic flagellate Breviata is a distinct anaerobic lineage within the eukaryote super-group Amoebozoa and challenges the unikont-bikont rooting of the tree of eukaryotes.

The development of phytoplankton communities was studied in floating enclosures. The enclosures were supplied with either surface water or water from 40 m depth. Nutrients with or without silicate were added in some of the experiments, while others recieved no artificial fertilization. It is shown that diatom dominance occurred irrespective of season if silicate concentration exceeded a thresho...

Heterosigma akashiwo is a golden-brown unicellular phytoflagellate with high potential to create harmful algal blooms (HABs) and kill fish in many coastal regions worldwide, resulting significant economic losses. Climate change global warming have been introduced as triggers that impact the frequency severity of H. other bloom-forming species past decades. In this review paper, author tried bri...

Chromera veliais a photosynthetic alga with a secondary plastid that represents the closest known photosynthetic relative of the apicomplexan parasites. The original description of this organism was based on brownish, immotile coccoid cells, which is the predominating stage ofC. veliain the culture. Here we provide a detailed light and electron microscopy description of coccoid cells ofC. velia...

(3) The function of the flagellate stage is one of sexual reproduction. (4) The parasite, after entering the fly's intestine in its infective " spore stage," penetrates the intestinal wall in the upper part of the intestine, and reaches the loose areolar tissue under the lining membrane of the intestine, in which it divides by fission, multiplies, and grows to maturity. (5) The process of growt...
