Determinants of bacterial pathogenicity and virulence
Number of View :54Determinants of bacterial pathogenicity and virulence Adhesion to host cells (adhesins). Breaching of host anatomical barriers (invasins) and colonization of tissues (aggressins). Strategies to overcome nonspecific defenses, especially antiphagocytic mechanisms (impedins). Strategies to overcome specific immunity, the most important of which is production of IgA proteases (impedins), molecular mimicry, and immunogen [...]

Meningitis – What is Meningitis? Meningitis Explained in Simple Language
Number of View :78 Meningitis is an inflammation of the membranes that cover the brain and spinal cord. The inflammation may be caused by infection with viruses, bacteria, or other microorganisms, and less commonly by certain drugs.

Escherichia coli Diarrhea
Number of View :62Escherichia coli diarrhea may affect infants or adults. Infants worldwide are especially susceptible to Escherichia coli diarrhea, since they usually have not yet developed immunity. Since water lost in the stool is often not adequately replaced, death from Escherichia coli diarrhea is usually due to dehydration. About 5 million children die yearly [...]
Escherichia coli e Coli – What is e coli (Escherichia coli)
Number of View :52E. colie is the abbreviation for Escherichia coli. E. coli is a gram-negative, rod-shaped bacterium that is found in the lower intestine of warm-blooded organisms. Most E. Escherichia coli normally resides in the colon without causing disease. However, there is an amazing amount of DNA being swapped about among the enterics by [...]
