It is motile at temperatures of 22–29°C (72–84°F), but becomes nonmotile at normal human body temperature. [ 1 ] [ 2 ] Y. enterocolitica infection causes the disease yersiniosis , which is an animal-borne disease occurring in humans, as well as in a wide array of animals such as cattle, deer, pigs, and birds.
Reduction of fecal coliform in wastewater may require the use of chlorine and other disinfectant chemicals, or UV disinfection treatment. Such materials may kill the fecal coliform and disease bacteria. They also kill bacteria essential to the proper balance of the aquatic environment, endangering the survival of species dependent on those ...
Coliform bacteria are defined as either motile or non-motile Gram-negative non-spore forming bacilli that possess β-galactosidase to produce acids and gases under their optimal growth temperature of 35–37 °C. [1] They can be aerobes or facultative aerobes, and are a commonly used indicator of low sanitary quality of foods, milk, and water. [2]
