Pathogenic bacteria secrete - (1) Antigens (2) Antibodies (3) Hormones (4) Interferons
by

1 Answer

Answer :

(1) Antigens Explanation: Pathogenic bacteria secrete various virulence factors, including toxins, lipases and pro-teases that allow them to infect, breakdown and colonize host tissue. Among various modes of action that the pathogenic bacteria use to damage the host, pore formation (by pore forming toxins (PFTs)) and lipid hydrolysis (by phospholipases) modes are common in damaging the eukaryotic cell membrane. PFTs in their monomeric form are extracellular diffusible and able to form hydrophilic pores in cell membrane while phospholipases cleaves and hydrolyzes the ester bonds of most phospholipids in cell membrane.
