Pathogens

Here comes a brief elucidation about pathogens!

        Pathogens are the foreign infectious microbes that make you sick or cause disease. These are microscopic disease-causing agents from outside of our body which can spread from one person to another. Types of pathogens are,

• Virus
• Bacteria
• Parasite
• Fungi

But some of the above are harmless. Examples for beneficial bacteria are soil decomposers and bacteria in digestive system. Pathogens enter our body through nose, ear, mouth, eyes, any cut and any other openings to the body. Pathogens disrupt the normal functioning by using human body as host to replicate and infect others. Our immune system is designed to attack and abolish them. 

Some diseases caused by the pathogens are

• Viral diseases - flu, common cold, hepatitis, AIDS
• Bacterial diseases - Salmonella food poisoning, Strep throat, Tuberculosis
• Fungal diseases - Fungal nail infection, vaginal infections
• Diseases caused by parasites - malaria, intestinal worms
