10 hours ago · Escherichia coli, one of the many species of bacteria present in the human gut. Gut microbiota, gut microbiome, or gut flora are the microorganisms, including bacteria, archaea, fungi, and viruses, that live in the digestive tracts of animals. [1] [2] The gastrointestinal metagenome is the aggregate of all the genomes of the gut microbiota.
5 days ago · Among bacteria, E. coli is a particularly powerful model system to study the organization, recognition, and activation mechanism of replication origins. E. coli oriC comprises an approximately ~260 bp region containing four types of initiator binding elements that differ in their affinities for DnaA and their dependencies on the co-factor ATP .
3 days ago · The bacteria on the right are fully resistant to three of seven and partially resistant to two of seven antibiotics tested. [1] Antimicrobial resistance ( AMR) occurs when microbes evolve mechanisms that protect them from the effects of antimicrobials (drugs used to treat infections). [2]
1 day ago · E. coli produces a powerful toxin that infects the lining of the small intestine. It takes only a small amount to cause infection. The symptoms are not pretty: fatigue, slight fever, cramps, pain, tenderness, nausea, vomiting and yes, diarrhea. Most symptoms are mild, but some can be severe. Rare cases cause a life-threatening form of kidney ...
2 days ago · Escherichia coli (E. coli) infections are a significant public health concern worldwide. Understanding the causes, symptoms, and treatment options for this infection is crucial in order to effectively manage and prevent its spread. E. coli is a type of bacteria commonly found in the intestines of humans and animals.
20 hours ago · Water pollution is the contamination of water by an excess amount of a substance that can cause harm to human beings and/or the ecosystem. The level of water pollution depends on the abundance of the pollutant, the ecological impact of the pollutant, and the use of the water. Pollutants are derived from biological, chemical, or physical processes.
5 days ago · The current classification of bacteria is based primarily on morphologic and biochemical characteristics. A scheme that divides the medically important organisms by genus is shown in Table 5–1 . For pedagogic purposes, this classification scheme deviates from those derived from strict taxonomic principles in two ways:
