The members of this family are part of the normal flora and commonly found in the digestive tracts of humans and animals. C. koseri may act as an opportunistic pathogen in individuals who are immunocompromised. [3] It rarely is community-acquired and mainly occurs as hospital-acquired infections. Infections caused by C. koseri can lead to ...
Deadliest animals as of 2016 [1] This is a list of the deadliest animals to humans worldwide, measured by the number of humans killed per year. Different lists have varying criteria and definitions, so lists from different sources disagree and can be contentious.
Typical genera include: [3] Citrobacter are peritrichous facultative anaerobic bacilli between 0.6–6 μm in length. [4] Citrobacter species inhabit intestinal flora without causing harm, but can lead to urinary tract infections, bacteremia, brain abscesses, pneumonia, intra abdominal sepsis, meningitis, and joint infections if they are given the opportunity.

The most extreme hyperthermophiles live on the superheated walls of deep-sea hydrothermal vents, requiring temperatures of at least 90 °C for survival. An extraordinary heat-tolerant hyperthermophile is Geogemma barossii (Strain 121) , [ 5 ] which has been able to double its population during 24 hours in an autoclave at 121 °C (hence its name).
C. rodentium is a non-motile, facultative aerobe that lives in the intestinal tract of mice. The indole production test is negative, and it cannot grow on citrate or KCN.It is negative for arginine dihydrolase (meaning it cannot utilize arginine as a carbon and energy source) and is negative for H 2 S production.
C. freundii is also a nitrogen-fixing bacteria, a process demonstrated in the living tissues of sassafras trees. This process provides evidence that they are partly responsible for reducing nitrate to nitrite in the environment. [8] C. freundii can also be found in the intestinal tracts of humans and other animals from diverse environmental ...
Some animals living in cold environments maintain their body temperature by preventing heat loss. Their fur grows more densely to increase the amount of insulation . Some animals are regionally heterothermic and are able to allow their less insulated extremities to cool to temperatures much lower than their core temperature—nearly to 0 °C ...
Enterobacteriaceae is a large family of Gram-negative bacteria.It includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in the phylum Pseudomonadota.
