The putrefactive gases evolved cause the skin to become emphysematous and crepitant and produce an offensive odour.

Traube also made an important contribution to the study of the etiology of disease. Together with Gscheidlen, an assistant of Rudolf Heidenhain he was the first to demonstrate via animal experiments that the organism has the ability to eliminate putrefactive bacteria. In evaluating the results, he distinguished chemical poisoning from infection with microorganisms on the one hand, and pathogenic from putrefactive bacteria on the other. Further, he was the first to propose a relation between immune system to infections and active oxygen in the blood cells.

On the other hand, there may be some beneficial effects to ingesting oligosaccharides such as raffinose and stachyose, namely, encouraging indigenous bifidobacteria in the colon against putrefactive bacteria. The insoluble carbohydrates in soybeans consist of the complex polysaccharides cellulose, hemicellulose, and pectin. The majority of soybean carbohydrates can be classed as belonging to dietary fiber.

Edwardsiella tarda is a member of the family Hafniaceae. The bacterium is a facultatively anaerobic, small, motile, gram negative, straight rod with flagella. Infection causes Edwardsiella septicemia (also known as ES, edwardsiellosis, emphysematous putrefactive disease of catfish, fish gangrene, and red disease) in channel catfish, eels, and flounder. Edwardsiella tarda is also found in largemouth bass and freshwater species such as rainbow trout.

Lactobacillus delbrueckii subsp. bulgaricus was first identified in 1905 by Stamen Grigorov, who named it Bacillus bulgaricus. Ilya Metchnikoff, a professor at the Pasteur Institute in Paris, researched the relationship between the longevity of Bulgarians and their consumption of yogurt. He had the idea that aging is caused by putrefactive activity, or proteolysis, by microbes that produce toxic substances in the intestine.

He was also the earliest American pioneer in the related field of disinfection in which he began with experiments (1878) with putrefactive bacteria. This work was continued in Washington and in the laboratories of Johns Hopkins Hospital in Baltimore, under the auspices of the American Public Health Association. For his essay "Disinfection and Individual Prophylaxis against Infectious Diseases" (1886), later translated into several languages, he was awarded the Lomb Prize. He oversaw creation the US Army enlisted hospital corps ("medics") in 1887.

Metchnikoff, at that time a professor at the Pasteur Institute in Paris, proposed the hypothesis that the aging process results from the activity of putrefactive (proteolytic) microbes producing toxic substances in the large bowel. Proteolytic bacteria such as clostridia, which are part of the normal gut microbiota, produce toxic substances including phenols, indols, and ammonia from the digestion of proteins. According to Metchnikoff, these compounds were responsible for what he called "intestinal autointoxication", which would cause the physical changes associated with old age.Arteriosclerosis and intestinal poisons.

Antiseptics (from Greek ἀντί anti, "against" and σηπτικός sēptikos, "putrefactive") are antimicrobial substances that are applied to living tissue/skin to reduce the possibility of infection, sepsis, or putrefaction. Antiseptics are generally distinguished from antibiotics by the latter's ability to safely destroy bacteria within the body, and from disinfectants, which destroy microorganisms found on non-living objects. Some antiseptics are true germicides, capable of destroying microbes (bacteriocidal), while others are bacteriostatic and only prevent or inhibit their growth. This source provides a summary of antiseptic techniques as understood at the time.

Carcasses have been soaked in formaldehyde to kill spores, though this has environmental contamination issues. Block burning of vegetation in large areas enclosing an anthrax outbreak has been tried; this, while environmentally destructive, causes healthy animals to move away from an area with carcasses in search of fresh grass. Some wildlife workers have experimented with covering fresh anthrax carcasses with shadecloth and heavy objects. This prevents some scavengers from opening the carcasses, thus allowing the putrefactive bacteria within the carcass to kill the vegetative B. anthracis cells and preventing sporulation.

Thus, the seeming division between innate immunity and acquired immunity is more practical than natural. Immunology's early feuds over whether immunity is innate or is acquired reflected limited perspectives. Sharing Pasteur's view of science as a means to suppress the problems plaguing humankind, Metchnikoff brought into France its first cultures of yogurt for probiotic microorganisms to foster health and longevity by suppressing the colon's putrefactive microorganisms alleged to foster the colon's toxic seepage, autointoxication. As the 20th century opened, British surgeons were still knife-happy, and called for "surgical bacteriology".

Human botulism is caused mainly by types A, B, E, and (rarely) F. Types C and D cause toxicity only in other animals. In October 2013, scientists released news of the discovery of type H, the first new botulism neurotoxin found in forty years. However, further studies showed type H to be a chimeric toxin composed of parts of types F and A (FA). Some types produce a characteristic putrefactive smell and digest meat (types A and some of B and F); these are said to be proteolytic; type E and some types of B, C, D and F are nonproteolytic and can go undetected because there is no strong odor associated with them.

The name came from the Greek words for "cheese" and "poison", and he considered them to be a kind of ptomaine, then thought to be a type of chemical that caused food poisoning. An ice cream poisoning incident the following year confirmed his suspicions. An ad for Vaughan's nuclein solution Vaughan and Novy published a book in 1886, Ptomaines and Leucomaines, or the Putrefactive and Physiological Alkaloids, which grew to 604 pages by its third printing in 1896; this and numerous journal articles led to national attention for the university and recognition for Vaughan as a leading researcher on bacteriology. There were skeptics of the tyrotoxicon theory at the time, and the ptomaine theory itself began to lose credibility by the early 20th century, leading Vaughan to conclude in 1909 that, "practically nothing is known about the precise chemical nature of these bacterial poisons".

He makes mention of a "queer hooting" sound, but attributes it to the exhalation of air prior to fatally transfusing blood from their human victims. Some evidence of audible communication is associated with the Martian Fighting-Machine, which are described emitting siren-like calls, and the repeated "Ulla, ulla" call (similar to a distress signal) that echoes throughout London after the mass death from bacterial infection of the Martians. Despite their advancement, the Martians' technology lacks the wheel, and it is implied they are ignorant of disease and decomposition. It is theorized that their advanced technology eliminated whatever indigenous diseases were present on Mars, and so they no longer remembered their effects. Ultimately, their lack of knowledge or preparation against any bacteria indigenous to Earth, causes their destruction here (though the epilogue states they may have successfully invaded Venus) by what Wells described as “putrefactive bacteria,” which digests organic materials upon death.
