Proteus Vulgaris
''Proteus vulgaris'' is a rod-shaped, nitrate-reducing, indole-positive and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. It can be found in soil, water, and fecal matter. It is grouped with the Morganellaceae and is an opportunistic pathogen of humans. It is known to cause wound infections and other species of its genera are known to cause urinary tract infections. ''P. vulgaris'' was one of the three species Hauser isolated from putrefied meat and identified (1885). Over the past two decades, the genus ''Proteus'', and in particular ''P. vulgaris'', has undergone a number of major taxonomic revisions. In 1982, ''P. vulgaris'' was separated into three biogroups on the basis of indole production. Biogroup one was indole negative and represented a new species, ''P. penneri'', while biogroups two and three remained together as ''P. vulgaris''.

Gustav Hauser
Gustav Hauser (13 July 1856 in Nördlingen – 30 June 1935 in Erlangen) was a German pathologist and bacteriologist. He studied medicine at the Universities of Munich and Erlangen, where he worked as an assistant in the gynecological clinic under Paul Zweifel and at the pathological institute of Friedrich Albert von Zenker. In 1883 he obtained his habilitation for pathological anatomy and bacteriology, and in 1895 became a full professor and director of the institute of pathology in Erlangen. In 1885, Hauser was the first to isolate the bacillus ''Proteus vulgaris''. He is also credited with developing a formalin for the preservation of bacterial cultures. In Erlangen, the thoroughfare ''Gustav-Hauser-Straße'' is named in his honor. Published works He was the author of works on numerous subjects in medicine. In the field of entomology, he was the author of ''Die Damaster-Coptolabrus-Gruppe der Gattung Carabus'' (The Damaster-Coptolabrus group and the genus ''Carabus'') ...

Dulcitol
Galactitol (dulcitol) is a sugar alcohol, the reduction product of galactose. It has a slightly sweet taste. In people with galactokinase deficiency, a form of galactosemia, excess dulcitol forms in the lens of the eye leading to cataracts. Galactitol is produced from galactose in a reaction catalyzed by aldose reductase. The other common galactose metabolism defect is a defect in galactose-1-phosphate uridylyltransferase Galactose-1-phosphate uridylyltransferase (or GALT, G1PUT) is an enzyme () responsible for converting ingested galactose to glucose. Galactose-1-phosphate uridylyltransferase (GALT) catalyzes the second step of the Leloir pathway of galactose ..., an autosomal recessive disorder, which also causes a buildup of galactitol as a result of increased concentrations of galactose-1-phosphate and galactose. This disorder leads to cataracts caused by galactitol buildup. References External links * {{Fructose and galactose metabolic intermediates Sugar alc ...

Proteus OX19
''Proteus'' OX19 is a strain of the ''Proteus vulgaris'' bacterium. History In 1915, Arthur Felix and Edward Weil discovered that ''Proteus'' OX19 reacted to the same human immune antibodies as typhus. Other ''Proteus'' strains were similarly used to create reagents for other rickettsiae diseases, thus resulting in the commercial Weil-Felix antibody-agglutination test. Use in fake epidemic in Poland Drs. Eugeniusz Lazowski and his medical-school friend Stanisław Matulewicz were practicing in the small town of Rozwadów in Poland during World War II. Dr. Matulewicz realized that since ''Proteus vulgaris'' strain OX19 was used to manufacture the then-common Weil-Felix antibody-agglutination test for typhus, inoculating villagers with dead Proteus would cause a false positive result without causing any disease. When the blood samples of the townspeople were sent to the German authorities for testing, authorities were convinced a typhus epidemic was raging in Rozwadów, ...

Ampicillin/sulbactam
Ampicillin/sulbactam is a fixed-dose combination medication of the common penicillin-derived antibiotic ampicillin and sulbactam, an inhibitor of bacterial beta-lactamase. Two different forms of the drug exist. The first, developed in 1987 and marketed in the United States under the brand name Unasyn, generic only outside the United States, is an intravenous antibiotic. The second, an oral form called sultamicillin, is marketed under the brand name Ampictam outside the United States, and generic only in the United States. Ampicillin/sulbactam is used to treat infections caused by bacteria resistant to beta-lactam antibiotics. Sulbactam blocks the enzyme which breaks down ampicillin and thereby allows ampicillin to attack and kill the bacteria. Medical uses Ampicillin/sulbactam has a wide array of medical use for many different types of infectious disease. It is usually reserved as a second-line therapy in cases where bacteria have become beta-lactamase resistant, rendering trad ...

Cefoperazone
Cefoperazone is a third-generation cephalosporin antibiotic, marketed by Pfizer under the name Cefobid. It is one of few cephalosporin antibiotics effective in treating ''Pseudomonas'' bacterial infections which are otherwise resistant to these antibiotics. It was patented in 1974 and approved for medical use in 1981. Cefoperazone/sulbactam (Sulperazon) is a co-formulation with sulbactam. Spectrum of bacterial susceptibility Cefoperazone has a broad spectrum of activity and has been used to target bacteria responsible for causing infections of the respiratory and urinary tract, skin, and the female genital tract.

Sulbactam
Sulbactam is a β-lactamase inhibitor. This drug is given in combination with β-lactam antibiotics to inhibit β-lactamase, an enzyme produced by bacteria that destroys the antibiotics. It was patented in 1977 and approved for medical use in 1986. Medical uses Sulbactam is able to inhibit the most common forms of β-lactamase but is not able to interact with the AmpC cephalosporinase. Thus, it confers little protection against bacteria such as ''Pseudomonas aeruginosa'', ''Citrobacter'', ''Enterobacter'', and ''Serratia'', which often express this gene. In the United States, sulbactam is combined to form ampicillin/sulbactam. It does possess some antibacterial activity when administered alone, but it is too weak to have any clinical importance. Its use in the UK is restricted to hospitals. The combination cefoperazone/sulbactam (Sulperazon) is available in many countries. Recently, its use in treating ''Acinetobacter'' sepsis is receiving renewed interest. Mechanism Sulbacta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Netilmicin
Netilmicin (1-N-ethylsisomicin) is a semisynthetic aminoglycoside antibiotic, and a derivative of sisomicin, produced by '' Micromonospora inyoensis''. Aminoglycoside antibiotics have the ability to kill a wide variety of bacteria. Netilmicin is not absorbed from the gut and is therefore only given by injection or infusion. It is only used in the treatment of serious infections particularly those resistant to gentamicin. It was patented in 1973 and approved for medical use in 1981. It was approved for medical use in the UK in December 2019, for the treatment of external infections of the eye. It is on the World Health Organization's List of Essential Medicines. Comparison with drugs According to the British National Formulary (BNF), netilmicin has similar activity to gentamicin, but less ototoxicity in those needing treatment for longer than 10 days. Netilmicin is active against a number of gentamicin-resistant Gram-negative bacteria but is less active against ''Pseudomonas ...

Urinary Tract Obstruction
Urinary tract obstruction is a urologic disease consisting of a decrease in the free passage of urine through one or both ureters and/or the urethra. It is a cause of urinary retention. Complete obstruction of the urinary tract requires prompt treatment for renal preservation.Chowdhury SH, Cozma AI, Chowdhury JH. Urinary Tract Obstruction. Essentials for the Canadian Medical Licensing Exam: Review and Prep for MCCQE Part I. 2nd edition. Wolters Kluwer. Hong Kong. 2017. Any sign of infection, such as fever and chills, in the context of obstruction to urine flow constitutes a urologic emergency. Causes Causes of urinary tract obstruction include: * Bladder stone and renal stone * Benign prostatic hyperplasia * Obstruction as a congenital disorder. Congenital urinary tract obstruction Urinary tract obstruction as a congenital disorder results in oligohydramnios which in turn can lead to the Potter sequence of atypical physical appearance. Pulmonary hypoplasia is by far the main cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
