Many different patterns of fission have been observed. Many bacteria and Protozoa simply split into two equal halves during cell division. Each half develops into new individual that can lead an independent life. Thus, cell division can be considered a

The preconjugant cell interactions of a marine species of Blepharisma (Protozoa Ciliata), collected on the Somalian coasts of the Indian Ocean, have been investigated. In freshwater species belonging to the same genus, cell recognition and union during the early phases of sexual reproduction are...
Fat supplements are well known for their multiple beneficial effects on ruminant health, reproduction and productivity, and as a source for certain bioactive compounds in ruminant products. On the other hand, numerous phytochemicals have demonstrated the potential to improve rumen fermentation through modi...
[23].Blastocystisspp., one of the most frequent protozoa infecting humans, was associated with abdominal discomfort, anorexia, diarrhoea and flatulence [23,24]. Other studies have suggested thatBlastocystisis a non-pathogenic protozoan, as it is frequently seen in healthy individuals (e.g. [23]...

Nutrition broths are aliquoted in test tubes and Erlenmeyer flasks. On the other hand, solidified agar is poured into Petri dishes, and to test tubes in slant form. Microbial cultures are inoculated through skillful streaking of culture to the medium. Once inoculated, mediums containing the ...
Type 1 immunity evolved to protect against intracellular pathogens such as bacteria, protozoa, and viruses and is characterized by group 1 innate lymphoid cells (ILC1s), T-helper (Th) 1 cells, and T-cytotoxic (Tc) 1 cells. Intercellular communication facilitates the elimination of infected cells...
