Proteus mirabilis

Susceptible Gram-negative organisms such as some Escherichia coli and Proteus mirabilis. 

Bacteria which are almost always sensitive to the sulphonamides include Strep, pneumoniae, /3-haemolytic streptococci, Escherichia coli and Proteus mirabilis those almost always resistant include Enterococcus faecalis, Ps. aeruginosa, indole-positive Proteus and Klebsiella whereas bacteria showing a marked variation in response include Staph, aureus, gonococci, El. influenzae and hospital strains of E. coli and Pr. mirabilis. 

Resistance to quinolones by efflux has been described in Staph, aureus and Proteus mirabilis. This gene has been designated nor A in Staph, aureus and is homologous to membrane transport proteins coupled to the electromotive force. These proteins have the ability to remove small amounts of quinolone from cells normally and nor A may have arisen as a result of mutations under selective pressure from quinolone use, resulting in a transport protein with increased affinity for these agents. 

Urease assay. When Proteus mirabilis grows in a urea-containing medium it hydrolyses the urea to ammonia and consequently raises the pH of the medium. This production of urease is inhibited by aminoglycoside antibiotics (inhibitors of protein synthesis Chapter 8). In practice, it is difficult to obtain reliable results by this method. 

Chlorate can serve as electron acceptor under anaerobic conditions (Thorell et al. 2003 Coates et al. 1999), and chlorate reductase has been found both in organisms such as Proteus mirabilis that can reduce chlorate but is unable to use to couple this to growth, and in true chlorate-respiring organisms. 

Moreover, it has been recognized that protonation of the Fe =0 group induces an increase of the quadrupole splitting with respect to the nonprotonated form. As a typical example, we mention the low-pH and high-pH forms of catalase from Proteus mirabilis [198] in Table 8.4.

Although proteins can be expressed in many heterologous production systems, including bacteria such as Proteus mirabilis [1], fungi such as Pichia pastoris [2, 3] and Aspergillus awamori [4] and insect cells [5, 6], the pharmaceutical industry has narrowed down process development to a small number of platform technologies ...

Acid Orange 7 and many other dyes Bacterial consortium TJ-1 consisting of Aeromonas caviae, Proteus mirabilis, and Rhodococcus globerulus Decolorization of Acid Orange 7 was significantly higher with the consortium as compared to the individual strains. More than 90% decolorization could be achieved even at 200 mg L 1 within 16 h. The consortium also decolorized 15 other azo dyes individually as well as a simulated wastewater containing a mixture of all the 16 azo dyes [58]...

The principal infecting organism is Escherichia coli, but Proteus mirabilis and Klebsiella pneumoniae account for some infections. Untreated bacteri-uria may result in pyelonephritis, preterm labor, preeclampsia, transient renal failure, and low birth weight.

These infections are predominantly caused by E. coli, and antimicrobial therapy should be directed against this organism initially. Other causes include S. saprophyticus and occasionally K. pneumoniae and Proteus mirabilis. 

Standard and the isolated strains of the following bacteria, namely Escherichia coli (ATCC 35218), Pseudomonas aeruginosa (ATCC 10145), Proteus mirabilis (ATCC 7002), Klebsiella pneumoniae (RSKK 574), Acinetobacter baumannii (RSKK 02026), Staphylococcus aureus (ATCC 25923), and Enterococcus faecalis (ATCC 29212) for determination of antibacterial activity, along with standard strains of Candida albicans (ATCC 10231) and C. parapsilosis (ATCC 22019) were used for determination of antifungal activity.
