The newly formulated Mycobacterium kansasii AccuProbe was evaluated, and the results obtained with the new version were compared to the results obtained with the old version of this test by using 116 M. kansasii strains, 1 Mycobacterium gastri strain, and 19 strains of several mycobacterial species. The sensitivity of this new formulation was 97.4% and the specificity was 100%. Still, three M. ...

A 4.2-kb PstI fragment harboring the gene cluster of the ribulose monophosphate (RuMP) pathway for formaldehyde fixation was identified in the chromosome of a gram-positive, facultative methylotroph, Mycobacterium gastri MB19, by using the coding region of 3-hexulose-6-phosphate synthase (HPS) as the hybridization probe. The PstI fragment contained three complete open reading frames (ORFs) whic...

Tuberculosis of the genitourinary tract is a well-known cause of male infertility. However, infertility from infection by nontuberculous mycobacterium has not been reported. Herein, we present a case of seminal vesiculitis due to Mycobacterium gastri in a diabetic patient leading to male infertility. Improvement in semen quality was noticed after 6 months of therapy with isoniazid, ethambutol a...

background: opioid peptides and their receptors are present in the majority of body tissues including gastrointestinal tract.  heroin is one of the opioid derivatives that abuse increasingly today.  so far, there is no study on the effect of acute heroin administration on gastric acid and pepsin secretion.   objective:  to define the effect of the acute heroin consumption on basal and vagal-sti...

thyroid hoemones effect gastric acid and pepsin secretion.however exact machanism(s) are not clear.this study was performed to compare the effect of vagal stimulation on acid an pepsin secretion in hypothyroid,hyperthyroid and control rars.each group consisted of 8 male and female rats(N-mari) weighing 246+_9 gr.hypo and hyperthyroid states were induced by administretion of methimazol (50mg/l i...

1. Of the three major human pepsins, pepsin 1 has greater proteolytic activity towards ovalbumin than has pepsin 3. Pepsin 5 has low activity towards this substrate. 2. Proteolytic pH-activity curves show only on pH maximum, about pH 1.4 for pepsin 1, pH 1.4--1.5 for pepsin 3 and pH 1.2--1.4 for pepsin 5. The curve for pepsin 3 has a shoulder between pH 2.4 and 3.4. 3. The rate of digestion of ...

The ability to digest mucus, mucolytic activity of isolated pepsins and samples of human gastric juice has been assayed by measuring the fall in viscosity when incubated with purified pig gastric mucus glycoprotein. Pure human pepsin 1, the peptic ulcer associated pepsin, digested gastric mucus glycoprotein at a faster rate than did pure human pepsin 3 (the principal human pepsin), or the equiv...

OBJECTIVES/HYPOTHESIS To assess if, as previously reported in the literature, bile acids inhibit pepsin activity, resulting in pepsin having a less important role in laryngopharyngeal damage in reflux disease. STUDY DESIGN Prospective translational research study. METHODS A total of 78 patient's fasting gastric juice samples were obtained from routine endoscopy. The total bile acid (TBA) co...
