Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
98 words
As an article of manufacture, a diagnostic kit for the rapid identification of uropathogenic bacteria which comprises a Petri-type dish which is structurally divided and contains in separate compartments culture media consisting of medium (1) comprising peptone, saccharose, lactose, dipotassium phosphate, eosin, methylene blue, agar, distilled water; medium (2) comprising peptone, beef extract, peptonized iron, sodium thiosulfate, DL-phenylalanine, agar, distilled water; medium (3) comprising magnesium sulfate, ammonium dihydrogen phosphate, disodium phosphate, sodium citrate, sodium chloride, Brom thymol blue, agar, distilled water; and medium (4) comprising urea, dextrose, sodium chloride, peptone, monosodium phosphate, phenol red, agar and distilled water.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
An article of manufacture in accordance with claim 1 wherein additional compartments are provided which contain culture media comprising (5) blood brain heart agar medium and (6) eosin methylene blue medium.
Claim 4
Dependent Claim
139 words
A procedure for rapid identification and evaluation and colony count of uropathogenic bacteria which comprises charging a four compartment Petri-type dish separately with medium (1) comprising peptone, saccharose, lactose, dipotassium phosphate, eosin, methylene blue, agar, distilled water; medium (2) comprising peptone, beef extract, peptonized iron, sodium thiosulfate, DL-phenylalanine, agar, distilled water; medium (3) comprising magnesium sulfate, ammonium dihydrogen phosphate, disodium phosphate, sodium citrate, sodium chloride, Brom thymol blue, agar, distilled water; and medium (4) comprising urea, dextrose, sodium chloride, peptone, monosodium phosphate, phenol red, agar and distilled water; charging a two compartment Petri dish separately with (5) blood brain heart agar medium, and (6) eosin methylene blue medium; inoculating all of the media with test urine; culturing the media; identifying uropathogens; counting uropathogen colonies; and determining drug susceptibility of the uropathogens with Mueller-Hinton plates according to the Bauer-Kirby method.
