Abstract: A child-resistant unit does holder includes a blister pack having a plurality of protrusions formed in a sheet and a unit dose disposed in each of the protrusions. The pack is slidably received in a sleeve which covers the protrusions to prevent a unit dose being dispensed from the pack. A releasable detent mechanism prevents slidable removal of the pack from the sleeve, and at least one of the protrusions forms a detent of the detent mechanism.

Abstract: A process of manufacturing test strips of the type comprising a length of porous carrier material capable of acting as a liquid flow path for a sample liquid and having at least zone downstream from a first end of the strip which zone contains an immobilized specific binding agent to act as a capture means during an assay to reveal the presence of an analyte in applied sample liquid, and in which process the specific binding agent is deposited onto a sheet of the porous carrier material which is then blocked and subdivided into a plurality of individual identical test strips, wherein blocking of the porous carrier material is achieved by applying a solution of blocking agent to the sheet upstream from the zone in an amount sufficient to ensure that the solution permeates downstream to beyond the zone.

Abstract: A test for microbial growth is carried out by culturing a microorgnism to be tested in a lliquid culture medium containing an enzymatically hydrolyzable fluorogenic substrate for a period of less than about 7 hours, measuring fluorescence of the culture medium resulting from hydrolysis of the fluorogenic substrate by growth of the microorganism, continuing culturing of the microorganism in the culture medium for an additional period, and measuring microorganism growth by a non-fluorescent method as a confirmatory test of growth determined from fluorescence. Preferably, the additional culture period is overnight and the non-fluorescent method is by visual inspection. The culture medium may be in the wall of a microtitre plate, and the culture medium can contain an antibiotic to test for sensitivity of a microorganism to the antibiotic or to test for minimum inhibitory concentration of the antibiotic.

Abstract: A method of determining the susceptibility of microorganisms to an antimicrobial substance wherein the microorganisms are cultured in the presence of the antimicrobial substance, and growth or lack of growth is assessed by detecting a fluorescent product resulting from the enzymatic hydrolysis of a fluorogenic substrate. The fluorogenic substrates include 7-N-(aminoacyl)-7-amido-4-methylcoumarin, 7-N-(alanyl)-7-amido-4-methylcoumarin, or a combination of 7-N-(alanyl)-7-amido-4-methylcoumarin and 4-methyl umbelliferyl phosphate.
