Bacteria are tiny, single-celled, prokaryotic microorganisms belonging to Kingdom Monera. Bacteria cells lack a nucleus and other organelles bound by a membrane and are structured by many different features. Bacteria have a flagella, cell wall, cell …show more content…
Pathogens are infectious organisms, such as a virus, fungus or bacterium, which cause a disease in another organisms. They carry or produce toxins, which act as antigens that can be identified as foreign by the host. The toxins pathogens produce are of two general types; exotoxins and endotoxins. Generally, endotoxins are produced by gram negative bacteria and exotoxins are produced by gram positive bacteria (Conjecture Corporation, 2016). The few pathogenic species of bacteria are highly infectious have they have effective modes of transmission. Pathogens can be spread many ways, such as by coming in contact with bodily fluids, ingesting undercooked food, swimming in contaminated water or personal …show more content…
These substances are common household chemicals which are used to kill bacteria. The two other types of antimicrobials which will be tested are disinfectants and antiseptics. Disinfectants kill nearly all microbials on hard surfaces, with the exception of spores and antiseptics are typically used to inactive or destroy organisms on skin or living tissue (Grainger Incorporation, 2016). Although there is no conclusive research about the effectiveness of different microbial agents, due to the features of bacteria constantly changing, there are theories about how they affect the growth of bacteria. Firstly, bleach is a disinfectant which is effective in killing bacteria due to the active ingredient sodium hypochlorite. There are theories which suggest that sodium hypochlorite has power as an oxidizing agent and when in contact with bacteria, fully oxidizes the cells of the germs and kills them (Sandoval,
