Explain how the inducible operon (Lac) is different from the repressible operon (Trp)? With inducible systems, the binding of the effector molecule to the repressor greatly reduces the affinity of the repressor for the operator, the repressor is released and transcription proceeds. The lac operon is an example of an inducible system(induced in the presence of lactose).With repressible systems, the binding of the effector molecule to the repressor greatly increases the affinity of repressor for the operator and the repressor binds and stops transcription.epressible: Repressible genes are those in which the presence of a substance (a co-repressor) in the environment turns off the expression of those genes (structural genes) involved in the metabolism of that substance. e.g., Tryptophan represses the expression of the trp genes.

Deinococcus radiodurans Deinococcus radiodurans. Deinococcus radiodurans is an extremophilic bacterium, one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and is therefore known as a polyextremophile and has been listed as the world's toughest bacterium in The Guinness Book Of World Records.

Chapter 12. Aerobic NonâSpore-Forming Gram-Positive Bacilli: Corynebacterium, Listeria, Erysipelothrix, Actinomycetes, and Related Pathogens Aerobic Non–Spore-Forming Gram-Positive Bacilli: Corynebacterium, Listeria, Erysipelothrix, Actinomycetes, and Related Pathogens. The non–spore-forming gram-positive bacilli are a diverse group of aerobic and anaerobic bacteria. This chapter focuses on the aerobic members of this group. The anaerobic, non–spore-forming gram-positive bacilli such as Propionibacterium species and Actinomyces species are discussed in Chapter 21 on anaerobic infections.

Escherichia coli Escherichia coli is a Gram-negative, facultatively anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms. Most E. coli strains are harmless, but some serotypes can cause serious food poisoning in their hosts, and are occasionally responsible for product recalls due to food contamination. The harmless strains are part of the normal flora of the gut, and can benefit their hosts by producing vitamin K2, and prevent

- Multidrug-resistant organisms are bacteria that have become resistant to certain antibiotics, and these antibiotics can no longer be used to control or kill the bacteria. Antibiotics are important medicines.

Coliform bacteria Coliform bacteria are a commonly used bacterial indicator of sanitary quality of foods and water.They are defined as rod-shaped Gram-negative non-spore forming and motile or non-motile bacteria which can ferment lactose with the production of acid and gas when incubated at 35–37°C.scherichia coli (E. coli) , a rod-shaped member of the coliform group, can be distinguished from most other coliforms by its ability to ferment lactose at 44°C in the fecal coliform test, and by its growth and color reaction on certain types of culture media.

Efficacy of antiseptic treatments Pseudomonas aeruginosa, a Gram-negative bacterium, is a common opportunist pathogen causing respiratory tract infections like pneumonia [5,6,18]. Generally, Gram-negative bacteria like P. aeruginosa are less permeable to QACs than non-sporulating, non-mycobacterial Gram-positive organisms [6,18]. The difference in uptake regulation by Gram-negative bacteria is mediated by structural differences in the outer membrane, porins, and efflux pumps [19,23].

Peptostreptococcus Infection Clinically significant anaerobic cocci include Peptostreptococcus species, Veillonella species (gram-negative cocci), and microaerophilic streptococci (aerotolerant). Anaerobic gram-positive cocci include various clinically significant species of the genus Peptostreptococcus. Peptostreptococcus infections can occur in all body sites, including the CNS, head, neck, chest, abdomen, pelvis, skin, bone, joint, and soft tissues.

- Neisseria gonorrhoeae, also known as gonococci (plural), or gonococcus (singular), is a species of Gram-negative coffee bean-shaped diplococci bacteria responsible for the sexually transmitted infection gonorrhea.o be specific, they grow on chocolate agar with carbon dioxide. These cocci are facultatively intracellular and typically appear in pairs (diplococci), in the shape of coffee beans. Of the eleven species of Neisseria that colonize humans, only two are pathogens.

- Miscellaneous bacterial strains: 1  Gram-variable-staining rod, facultative anaerobic bacteria (actually has a Gram-positive cell wall, but because the cell wall is so thin it can appear either Gram-positive or Gram-negative under the microscope).  Small (1-1.5 µm diameter) non-spore forming, non-motile coccobacilli.

APES Diseases Escherichia coli (E. coli) bacteria normally live in the intestines of people and animals. Most E. coli are harmless and actually are an important part of a healthy human intestinal tract. However, some E. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract.ou might hear these bacteria called verocytotoxic E. coli (VTEC) or enterohemorrhagic E. coli (EHEC); these all refer generally to the same group of bacteria. The strain of Shiga toxin-producing E. coli O104:H4 that caused a large outbreak in Europe in 2011 was frequently referred to as EHEC.

- A paramecium is a small one celled (unicellular) living organism that can move, digest food, and reproduce. They belong to the kingdom of Protista, which is a group (family) of similar living micro-organisms.Micro-organism means they are a very small living cell.hree of them are Paramecium aurelia, Paramecium bursaria, and the Paramecium caudatum. Notice that the first part of the name (Genus) is capitalized and the second (Species) name is not. That is the standard way to write the names. These names are similar to your name-they specify you in particular.

- Pyogenic Cocci. The pyogenic cocci are spherical bacteria that cause various suppurative (pus-producing) infections in animals. Included are the Gram-positive cocci Staphylococcus aureus, Streptococcus pyogenes and Streptococcus pneumoniae, and the Gram-negative cocci, Neisseria gonorrhoeae and N. meningitidis.In terms of their phylogeny, physiology and genetics, these genera of bacteria are unrelated to one another.ifferent strains of S. aureus differ in the range of diseases they can cause, including boils and pimples, wound infections, pneumonia, osteomyelitis, septicemia, food intoxication, and toxic shock syndrome. S. aureus is the leading cause of nosocomial (hospital-acquired) infections by Gram-positive bacteria.

Proteus mirabilis Proteus mirabilis is a Gram-negative, rod-shaped bacterium belonging to the enterobacteriaceae family. It is facultatively anaerobic, not requiring oxygen for survival and reproduction and may even die in the presence of oxygen.Proteus mirabilis are found free-living in moist habitats, such as [water] and soil.t is primarily community-acquired, and most frequent in the urinary tract. Proteus mirabilis is a significant pathogen of the urinary tract. Urinary tract infection is a process following certain steps; it first starts with colonization of the bladder, which causes cystitis.
