Question
Chapter 3, Problem 4TQ
Summary Introduction
To review:
The method used by pathogenic bacteria to avoid being engulfed by phagocytes present in human blood also, mention the role of various aspects of the cell structure for phagocytosis prevention.
Introduction:
Â
Bacteria are prokaryotic cells that could be beneficial or harmful to other organisms. The bacteria that are able to cause disease in human beings are known as pathogenic bacteria. These pathogenic bacteria enter the human body through the genital opening, water, air, and food and can cause a range of harmful effects.
