Cysticercus refers to a tapeworm larva which has a sac filled with fluid that contains scolex which is invaginated. It is normally located within the immediate host tissues, with the capability of developing into mature tapeworm when a desirable host feeds on it ("Cysticercus | Definition of Cysticercus by Merriam-Webster."). Cysticerci are responsible for causing an infection known as cysticercosis. There are several species of cysticerci. The two common species of cysticercus are Tanenia solium whose larva is known as Cysticercus cellulosae. It develops in the swine muscles frequently. The second species is the Taeniarhynchus saginatus. Its larva is known ...

Chapter 4: Prokaryotic Cells and microorganisms

This chapter looks at the morphology, and pathogenic mechanisms of prokaryotic cells and microorganisms respectively. It discusses in detail the structural components, functions of the different organelles of prokaryotic cells as well as feeding and survival mechanisms of prokaryotic microorganisms.

Prokaryotic cells have a specialized cellular structure. Prokaryotes are unicellular and their cells have no cellular organelles, that is, a membrane does not surround their nucleus. These cells contain intricate phospholipids, sterols, and sphingolipids. They are typically 1-5µm in diameter .

Their outer surface is covered by glycocalyx, which is a gel like cellular envelope that provides prokaryotic cells with protection against ...
