The bacteria grow best at warm temperatures [4] and thrive at water temperatures between 25 and 45 °C (77 and 113 °F), with an optimum temperature of 35 °C (95 °F). [23] Temperatures above 60 °C (140 °F) kill the bacteria. [ 24 ]
The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases. The intrinsic incubation period is the time taken by an organism to complete its development in the definitive host. The extrinsic incubation period is the time taken by an organism to develop in the intermediate host. [citation needed]
The incubation period of about 24 hours is followed by intense watery or bloody diarrhea accompanied by nausea, vomiting, abdominal cramps, and sometimes a fever. Symptoms typically resolve within 72 hours, but can persist for up to 10 days in immunocompromised individuals.
Melioidosis is an infectious disease caused by a gram-negative bacterium called Burkholderia pseudomallei. [1] Most people exposed to B. pseudomallei experience no symptoms; however, those who do experience symptoms have signs and symptoms that range from mild, such as fever and skin changes, to severe with pneumonia, abscesses, and septic shock that could cause death.

The bacteria are spread by airborne droplets and the disease's incubation period is 7–10 days on average (range 6–20 days). [1] [2] Humans are the only known reservoir for B. pertussis. [3] The complete B. pertussis genome of 4,086,186 base pairs was published in 2003. [4]
Although L. monocytogenes has low infectivity, it is hardy and can grow in a refrigerator temperature of 4 °C (39.2 °F) up to the human body temperature of 37 °C (98.6 °F). [5] It is the usual cause of the relatively rare bacterial disease listeriosis, an infection caused by eating food contaminated with the bacteria.
8) Once food has been cooked, all the bacteria have been killed The possibility of bacterial growth actually increases after cooking, because the drop in temperature allows bacteria to thrive. 9 ...
The incubation period of Mycobacterium leprae ranges from 9 months to 20 years. [42] The bacterium replicates intracellularly inside histiocytes and nerve cells and has two forms. One form is "tuberculoid", which induces a cell-mediated response that limits its growth, and has few detectible bacilli (paucibacillary). [ 43 ]
