Question

certain pathogens are tissue and organ specific justify the statement with suitable example​

Answer 1

Answer:

Certain pathogens are tissue and organ specific because the nutrients required for them are present only in those organs.  

Explanation:

For example when a plasmodium falciparum that is the malarial parasite enters the hum body through a mosquito it directly invades the red blood corpuscles of the body.

It infects and multiplies in population only in the Red blood corpuscles, after it has reached its complete capacity that is the red blood cells are tightly packed with the parasites, then they burst open and display the infection.  

Answer 2

Pathogens are tissue and organ:

Pathogens belong mainly to five different classes: virus, bacteria, fungi, protozoa and worms. Many of these pathogens occur in specific organs, specific tissue or cell types that are advantageous and required for their survival within the host. The filaria worms stay in the ‘human lymph nodes’ as cause filariasis.  

Streptococcus pneumonia in lungs cause pneumonia, the malarial parasite Plasmodium invades the red blood cells, Salmonella typhii that causes typhoid infects the lining of small intestine, Entamoeba hystolytica infects the large intestine and causes amoebiosis.
