A method for the continuous culturing of microbes in a plug-flow reactor which comprises the steps of:

Method for continuous culturing of microbes

A method for detecting the presence of Neisseria bacteria in a fluid sample which comprises bringing immobilized antibody specific for the enzyme 1,2-propanediol dehydrogenase which is released from such bacteria upon lysis thereof, into contact with a lysed sample, isolating the immobilized antibody or resulting immobilized antibody-enzyme complex or mixture thereof, and then testing the isolated material for enzymatic activity.

Detecting Neisseria via immobilized antibody-enzyme complex

Bacteria immobilized by adsorption on an inorganic carrier are stabilized by carrying out the adsorption procedure in the presence of from about 1 to about 20% weight per volume of sucrose of nonfat dry milk solids and lyophilizing the adsorbed bacteria.

Stabilization of immobilized bacteria

This invention relates to means for transporting clinical specimens wherein the activity thereof can be retained for relatively long periods of time. The crux of the invention resides in a liquid reagent capable of preserving or stabilizing the activity of a particular specimen. Where the clinical specimen is Neisseria gonorrhoeae, the preferred liquid reagent consists of an aqueous mixture of cysteine and TRIS (Trihydroxymethylaminomethane) buffer. A convenient type of specimen collector comprises a swab. Again, where the clinical specimen is Neisseria gonorrhoeae, the preferred swab consists of calcium alginate. An apparatus particularly useful for transporting specimens comprises a screw-capped container having a liquid reagent sealed into the bottom portion thereof capable of preserving the activity of a particular specimen, and a specimen collector attachable to the inside of said screw cap through a longitudinal element of sufficient length to immerse said collector into said liquid. After a specimen has been obtained, the collector, attached to the screw cap, is forced through the seal into the liquid preservative as the screw cap is fastened tightly onto the container.

Transport system for clinical specimens

Device for simultaneous recognition of group D streptococci and the differentiation of members of that group into enterococci and nonenterococci bacteria. Device comprises an elongated substantially cylindrical transparent tube having upper and lower chambers joined by a conduit having a smallest diameter smaller than either chamber. The upper chamber contains a semi-solid bile-esculin medium capable of indicating the presence of group D streptococci. The lower chamber contains a semi-solid enterococci distinguishing medium having a NaCl content of at least about 6.5%. Media in the two chambers are separated by a gas (e.g., air) within the conduit.

Device for recognition and differentiation of group D streptococci

A microbial growth medium for distinguishing Neisseria gonorrhoeae from Neisseria meningitidis. The medium comprises a gonococci and meningococci specific medium having incorporated therein a quantity of 8-anilino-1-naphthalene-sulfonic acid (ANS) or a salt thereof, at a concentration sufficient to permit the growth of the meningococci and inhibit the growth of the gonococci.
