All living things can be divided into two types of cells: prokaryotes and eukaryotes. Eukaryotic cells have a nucleus and other cell structures that are bound by a distinct membrane. Bacteria, as prokaryotic cells, lack these internal membrane-bound structures. This distinction is considered to be...

In so many bacterial experiments, assuming that all the individual cells of Esche-richia coli or other bacterial species in a particular flask are identical in terms of genotype and phenotype is reasonable and usually works well. Indeed, accepting this premise led several generations of microbiolo...
which can cause strep throat and scarlet fever; staphylococcus, specifically Staphylococcus aureus, which can cause food poisoning and toxic shock syndrome; and meningococcus, which can cause a number of meningococcal diseases, including epidemic bacterial meningitis. ...
The treatment for high WBCs depends on what’s causing the levels to be elevated. For example, bacterial infections can cause high white blood cells and can often be treated with antibiotics. Myeloproliferative Disorders Myeloproliferativedisorders are a specific group of conditions that can affect bl...

Their effect on the bacterial content of the streams to which they are discharged may be gauged from the fact that, in the effluent from the small rural sewage works, which was of consistently good quality when judged by chemical criteria, there were on the average about 160,000 cells of ...
or spherical bacteria. When cocci divide or reproduce they create different patterns, depending on the type. Types of coccus bacteria include Diplococcus bacteria, Streptococcus bacteria, Staphylococcus bacteria and Enterococcus bacteria. They are named depending on how their bacterial cells are arranged....
This model relies on spatially-restricted stem, progenitor and differentiated populations in the epithelial and mesenchymal compartments underlying the coordinated expansion of two major branches of pulpal cells and diverse epithelial subtypes. Further comparisons of human and mouse teeth yield both ...
