Infection Mechanism

S. epidermidis is implicated in many medical implant infections. Mechanical heart valves, shunts, catheters and orthopedic devices are examples of implanted devices... 

Adverse effects of prosthesis insertion include early and late onset infection, mechanical failure, and erosion of the rods through the penis. 

Exploded view of the human immunodeficiency virus. It is an RNA (retrovirus) virus that contains surface proteins composed of a knoblike glycoprotein (gpl20) linked to a transmembrane stalk (gp41). These surface proteins are the infective mechanisms that allow the virus to bind to CD4 proteins of cells, such as T4 lymphocytes and monocytes. 

As an important membrane anchored molecule in Gram-negative bacteria that can activate the immune response, LPS and lipid A are largely needed for research to understand infection mechanism of bacterial pathogens. Methods for extraction and purification of LPS and lipid A still need to be modified to increase the yield and purity, so do the methods for analysis of LPS.

In addition to their dietary importance, the proteins are the most abundant macromolecules in the cell, and they carry out most of the work in a cell. Protection of the body from infection, mechanical support and strength, and catalysis of metabolic reactions— all are functions of proteins that are essential to life.

Recently Ravish and Kirkiacharian 60) have analyzed the effect of a series of natural and synthetic homoisoflavanones on Phytophthora parasitica and on the activity of some of its enzymes. They have found inhibition of in vitro growth and sporogenesis of the microorganism. Enzymatic studies revealed no remarkable inhibition of a polyphenol oxidase or of a- and P-amylases, whereas P-glucosidase and five pectinolytic enzymes (endo PTE/PATE and endo PMG/PG) which are directly involved in the infection mechanism are inhibited to a varying extent. No structure-dependent effects were readily perceptible except that fully methylated compounds seemed to be relatively ineffective. 

Biofilm formation is believed to play a crucial role in infection mechanisms. This is the case, for example, of Staphylocoaus epidermidis and P. aeruginosa, and for the genera Escherichia, Legionella, Staphylococcus, Streptococcus, and Vibrio involved in clinical chronic infections. Their biofilms ensure protection firom antibiotics preventing penetration of different agents. i...
