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]
Morganella morganii is a species of Gram-negative bacteria. [2] It has a commensal relationship within the intestinal tracts of humans, mammals, and reptiles as normal flora. [ 2 ] Although M. morganii has a wide distribution, it is considered an uncommon cause of community-acquired infection, and it is most often encountered in postoperative ...
This bacterium can colonize in the respiratory tract, genital tract, stool, and urinary tract. However, P. vulneris is most often associated with wounds and has been known to colonize open wounds of both humans and animals. This association gave the bacterium its species name, vulneris, which is Latin for wound. It has also been infrequently ...
Additionally, bacterial staining or culture of fluid taken from the wound helps identify Clostridium perfringens and other bacteria responsible for the infection. In some cases, a biopsy is performed, where a sample of the affected tissue is analyzed for signs of damage or necrosis.
The genus Enterobacter is a member of the coliform group of bacteria. It does not belong to the fecal coliforms (or thermotolerant coliforms) group of bacteria, unlike Escherichia coli, because it is incapable of growth at 44.5 °C in the presence of bile salts. [citation needed] Some of them show quorum sensing properties. [2] [3]
For pseudomonal wound infections, acetic acid with concentrations from 0.5% to 5% can be an effective bacteriostatic agent in eliminating the bacteria from the wound. Usually a sterile gauze soaked with acetic acid is placed on the wound after irrigation with normal saline. Dressing would be done once per day.
Aeromonas is a genus of Gram-negative, facultative anaerobic, rod-shaped, bacteria that morphologically resemble members of the family Enterobacteriaceae. Most of the 14 described species have been associated with human diseases. The most important pathogens are A. hydrophila, A. caviae, and A. veronii biovar sobria. The organisms are ...
In humans A. veronii can cause diseases ranging from wound infections and diarrhea to sepsis in immunocompromised patients. In leeches, this bacterium is thought to function as a symbiote aiding in the digestion of blood, provision of nutrients, or preventing other bacteria from growing. [3]
