Those drugs particularly Chemotherapeutic/Antibiotic that are bactericidal (Killing of bacteria) in nature and cause destruction of bacteria. Penicillin and cephelosporins are commonest example of Bactericidal drugs
These are the bactericidal lamps with xenon.
Bactericidal antimicrobial agents kill the microbe, whereas bactericidal agents inhibit the growth of the microbe. Chloehexidine is an agent that kills bacteria, thus, it is considered a bactericidal antimicrobial agent.
it is bactericidal b/c it binds 30s ribosomal subunit &inhibit protein synthesis
Bacteriostatic
Bactericidal
chemical barrier
Fluids derived from some plants have bactericidal properties. Some of the best known ones are lemon juice and onion juice.

Before 1980's you used to treat typhoid fever with Chloramphenicol antibiotic for 10 to 14 days. It is a 'bacteriostatic' antibiotic and there used to be many cases of chronic carrier. Few used to relapse and responded well to chloramphenicol again. Then there was emergence of chloramphenicol resistant typhoid fever. It was a serious threat to health system. Fortunately fluroqunoline group of antibacterials came to the rescue. And most cases can be managed with this antibacterial drug. This being 'bactericidal' drug you do-not have many carriers of typhoid fever. Another drug being ceftriaxone injections is also 'bactericidal' antibiotic. And you do-not have many cases of chronic carrier of typhoid fever. You treat the typhoid carriers with one of the 'bactericidal' drug. But, if you happen to find a person of typhoid fever for 40 years, please do not get surprised. As in biology this can easily happen. ( It is interesting to read the story of 'Typhoid Merry' from USA.)
Pyrazinamide is considered bactericidal against Mycobacterium tuberculosis. It works by disrupting the mycolic acid synthesis in the cell wall, leading to cell death.
Bacteriostatic disinfectants inhibit the growth and reproduction of bacteria without killing them, while bactericidal disinfectants kill bacteria. Bacteriostatic disinfectants may not eliminate all bacteria, but they can prevent their proliferation. On the other hand, bactericidal disinfectants are more effective at completely destroying bacteria.
