A modified 1-min iodometric paper strip test for penicillinase activity was developed for detection of beta-lactamase-producing isolates of Haemophilus influenzae and Neisseria gonorrhoeae. The test is simple to perform and uses reagent-impregnated strips that may be stored for 1 year or more prior to use.

1. Describe the principle and procedure. 2. Compare and contrast reagent strip characteristics among manufacturers. 3. Interpret results. 4. Define expected normal values. 5. Suggest causes for abnormal findings. 6. Identify sources of error. 7. Suggest appropriate confirmatory tests. 8. Correlate results of chemical tests with those of physical examination. 9. Predict findings of microscopic e...

We describe a method for determining free and total cholesterol in extracts of rat-liver lipids by use of a cholesterol esterase/cholesterol oxidase enzymatic kit (Boehringer Mannheim Corp). The lipids are solubilized (as micelles) directly into the aqueous reagent mixture. Results of the enzymatic method correlate well with those obtained by an acid/ferric chloride assay of digitonin precipita...

The sensitivity of a reagent strip test for the diagnosis of schistosomiasis by detecting circulating cathodic antigen (CCA) in urine was evaluated under field conditions using 251 stool and urine samples collected from a Schistosoma mansoni-endemic area of Ethiopia. The specificity of the test was evaluated in an area where schistosomiasis is not endemic. Stool samples were examined microscopi...

background: ascitic fluid infection is presumptively diagnosed when the fluid polymorph nuclear (pmn) concentration equals or exceeds 250 cells /mic,l. the leukocyte esterase (le) test has been shown to be a good predictor of the presence of pmns in urine and other body fluids. this study examines of value of multistix 8sg dipstick test for rapid diagnosis of infected ascitic fluid. materials a...

Background: One of the worst sequelae cirrhosis and ascites is spontaneous bacterial peritonitis (SBP). Early detection treatment SBP are therefore essential for survival because this complication linked to a high death risk if antibiotics not administered promptly. Leukocyte esterase dipstick testing can identify quickly. Objective: To evaluate diagnostic accuracy leucocyte test taking ascitic...

Asymptomatic bacteriuria (ASB) is the existence of bacteria in a patient's properly gathered urine who has no obvious symptoms urinary tract infection, which common females, with prevalence rate 2-11%, ASB during pregnancy influenced by range factors including; mechanical compression, changes immune and renal systems, if untreated, it can lead to cystitis pyelonephritis. Our aim evaluate sensit...

BACKGROUND Moringa stenopetala has been used in traditional health systems to treat diabetes mellitus. One of the successful methods to prevent of the onset of diabetes is to control postprandial hyperglycemia by the inhibition of α-glucosidase and pancreatic α-amylase activities, resulting in the aggressive delay of the carbohydrate digestion of absorbable monosaccharides. The aim of the prese...
