Having brought the medium to the required reaction, heat again for half an hour at 100^ C, to complete the precipitation of phosphates. Filter through Swedish filter-paper into sterile tubes (10 c.c m each). Plug the tubes with cotton-wool, and then sterilise these in the steamer on three successive days for twenty minutes. Glucose and Lactose Broth. — ^These are simply the above ordinary broths, containing 1 or ? per cent, of either grape- or milk-sugar. The steps in the preparation are the same as those just described. Nutrient Gelatin.— This is made by adding 10 to 15 per cent, of gold- labelled gelatin, cut into small pieces, to ordinary broth prepared as above, and then melting it by steaming at 100° C. for one hour. Estimate the re- action of the medium mass, as explained for broth, then add sufficient normal soda solution to render the reaction of the calculated bulk of medium + 10. Replace in the steamer, and keep at 100° C. for twentjr minutes to precipitate all phosphates. Allow to cool to 60° C. Add the whites of two eggs for each litre of medium, replace in steamer at 100° C. for half an hour ; then filter through Chardin paper into sterile tubes. Sterilise these at 100° C. for twenty minutes on each of three consecutive days. Glucose and Lactose Gelatin are made in the same way, adding 1 to 2 per cent, of the respective sugars. Nutrient Agar-agar. — ^Add fifteen grammes of agar, cut into very fine fragments, to a litre of ordinary broth, prepared as explained. Dissolve by heating at 100° C. for an hour and a half. Estimate the reaction of the medium mass as explained under the head of " Broth " ; then add sufficient 980 APPENDIX normal soda solution to render the reaction of the calculated bulk of tlie medium + 10. Replace in the steamer for twenty minutes to complete the precipitation of phosphates. Allow the medium to cool to 60° C, add whites of two eggs, replace in steamer, and keep at 100° C. for half an hour. Now filter through Chardin paper, by the aid of a hot-water funnel, into sterile tubes. Sterilise in steamer at 100° C. for half an hour on each of three successive days. Glycerin-agar is made in the same way, 6 per cent, of glyceiin beii^ added after filtration. (glucose and Lactose Agar are made as under ordinary agar, 2 per cent, of the respective sugars being added, as the case may be. If required to be tinted with neutrfil red, 2 per cent, of a half per cent, solution of neutral red is added before filtration. Peptone Solution.— One to two per cent, of Witte's peptone with 0*5 per cent, of common salt are dissolved in distilled water by heating. The fluid is then filtered, placed in tubes, and sterilised. In this medium, cholera vibrios grow with great rapidity. It is also much used for testing the formation of indol by different bacteria. Qlucose-peptone Solution.— Made by dissolving, by means of heat, 1 gramme of glucose, 1 gramme of peptone, and 0*5 gramme of salt in 100 c.c. of distilled water. TUs is filtered, rendered neutral to litmus, placed in steamer at 100^ C. for half an hour, then tubed into test-tubes containing inverted fermentation tubes, and sterilised for twenty minutes at 100° C. on three successive days. Lactose-peptone Solution.— Prepared as the foregoing, substi- tuting lactose for the glucose. Sucrose, Mannite, Dulcite, Bafflnose and other carbo- hydrate or glucoside Peptone Solutions are prepared as the foregoing, substituting the corresponding constituent. Proskauer and Oapaldi's Media.— The No. 1 medium has the following composition : — Asparagin and mannite, of each 0*2 per cent. ; potas- sium mono-phosphate, 0*2 per cent. ; sodium chloride and calcium chloride, of each 002 per cent. ; and of magnesium sulphate, 0*01 per cent. The re- agents are dissolved in distilled water, sterilised for an hour at 100° C. The medium is then rendered neutral to litmus by the addition of sufficient normal caustic soda solution. Sufficent litmus solution is added to give the medium a purple tint. It is now tubed and sterilised in the usual way for twenty minutes at 100° C. on three successive days. The No. 2 medium contains 2 per cent, of Witte's peptone and 0*1 per cent, of mannite dissolved in distilled water. Sterilised at 100° C. for an hour, this will now be found to be alkaline ; it is neict carefully rendered neutral to litmus by the addition of a saturated solution of citric acid. Litmus solution is added to give it a deep red colour. It is -now tubed and sterilised in the usual way for twenty minutes at 100° C. on three successive days. These media are of great value in the differential diagnosis between the B. coU and the B. typhosus. Milk. — ^Fresh milk and free from any preservative is steamed for half an hour at 100°, and then placed in a cool place over night for separation of cream. The milk is then syphoned off from beneath the cream, and placed in sterile tubes ; if necessary, sufficient litmus solution is added to give it a purple tinge. The tubes are plugged, and then sterilised at 100° C. for twenty minutes on each of three successive days. Potato Medium. — ^A large potato is well washed and scrubbed with a brush. A cylinder is then bored from its interior, and cut obliquely. The APPENDIX 981 peel from the ends is cut oB, and the wedges so obtained allowed to soak over ni^ht in cold water to get rid of any excess of starch. Each wedge of potato IS then placed in a test-tube previously fitted with a pad of cotton- wool at the bottom, and filled for about half an inch in depth with distilled water. The tube is now plugged with cotton-wool, and sterilised at 100*^ C. for twenty minutes on three successive days. Drigalski-Oonradi Medium. (1) Agar preparation.— To 3 lb. of finely cut beef add 2 litres of water ; allow the mixture to stand until next day. Boil the expressed meat-juice for one hour and filter ; add 20 grammes of Witte's peptone, 20 grammes of nutrose, 10 grammes of sodium chloride, and boil the whole again for an hour and then filter. Now add 70 grammes of agar, boil for three hours, render slightly alkaline to litmus, filter and boil for half an hour. (2) lAtmus aohUion. — Take 260 c.c. of either Kubel and Tiemann's litmus solution, or of a purified litmus solution, prepared as ex- plained later ; boil for ten minutes ; add 30 grammes of lactose and boil for fifteen minutes. Add this hot litmus-lactose solution to the liquid-agar solution and mix ; render it faintly alkaline ; then add 4 c.c. of a hot sterile solution of 10 per cent, water-free soda and 20 c.c. of a freshly prepared solution of 0-1 gramme crystal violet (Hochst) in 100 c.c. of warm sterile distilled water. The result is a meat- water peptone nutrose agar, containing 13 per cent, litmus and 001 per 1000 crystal violet. Tube, and sterilise in steam for thirty minutes. Eyre ^ has suggested^modified nutrose agar which is equally satisfactory. w Litmus Solution. — ^For bacteriological work a pure solution of the blue dye (azolitmin) should be used. It is freely soluble in water, but in- soluble in alcohol. It can be prepared as follows : — Digest 2 ounces of powdered litmus with fresh quantities of hot water until all the colouring- matter is dissolved out ; allow to settle and decant off the fiuid. Evaporate this solution down from about a litre to 300 c.c. ; add a slight excess of acetic acid ; evaporate further over a water-bath until the liquid becomes pasty. Add 200 c.c. of methylated spirit and mix. The spirit precipitates the azolitmin, leaving the red dye in solution. Filter. Wash out dish and filter with methylated spirit. Now dissolve the pure blue colouring-matter on the filter in warm distilled water and dilute to 500 c.c. This azolitmin solution is far more sensitive than ordinary litmus solution. Neutral-red Bile-salt Agar. — Dissolve 20 grammes of agar in a litre of water in an autoclave ; add 5 grammes of sodium taurocholate and 20 grammes of peptone. Clear by means of white of egg in usual way and filter. Now add 10 grammes of lactose and 5 c.c. of a 1 per cent, solution of neutral red. Tube and sterilise for twenty minutes on two successive days. It is best to have the neutral-red solution freshly prepared. Endo's Fuchsin-agar.— To 1 litre of water add 500 grammes of minced beef, 10 grammes of peptone, 5 grammes of sodium chloride, and 30 grammes of agar. Boil well, filter, and neutralise ; then make alkaline by adding 10 c.c. of a 10 per cent, solution of sodium carbonate. Now add 10 grammes of lactose, and 5 c.c. of a 10 per cent, fuchsin solution in 96 per cent, of alcohol. The medium is now a dark red colour. Twenty-five c.c. of a 10 per cent, sodium sulphite solution are now added. The medium gradually decolorises. Tube and sterilise once for half an hour in steam. On this medium, colonies of B, coli are red, those of B. typhosus are colourless and transparent. The finished medium should be kept in the dark, other- wise it turns red. Gachtgens has suggested a modification of this medium by adding 0*33 per cent, of caffein and giving it an alkalinity equal to • Eyre : Trans, Paiholog. 8oc Ltrndon^ vol. Iv. p. 91. _ 982 APPENDIX 1*5 per cent, normal NaOH solution below the neutral point of phenol- phtnalein. Malachite-g:reen Agar. — ^Macerate 3 lb. of minced beef in 2 litres of water for twenty hours. Express, boil, filter, add 3 per cent, of agar and boil now for three hours. Add 1 per cent, of peptone, 0*5 per cent, of sodium chloride ; neutralise to the litmus neutral point by soda solution with dupli- test paper, boil again for an hour and filter. This finished agar will now be acid. It may now be run into flasks and sterilised in the usual way. Before use and adding the malachite-green, the agar must be melted and made alkaline with sterile soda solution, testing with duplitest paper until the red slip is red-violet. To 100 c.c. of the hot agar add 1 c.c. of a 1 in 60 solu- tion of malachite-green in distilled water. This agar now contains malachite- green 1 in 6000. By this strength, the growth of B, coU is diminished. The B, typhosus colonies are also retarded, but appear as minute glistening points which subsequently colour the agar yellow. Alkaline Litmus-glucose Agar.— Prepare ordinary agar with 2 per cent, glucose as already explained. Render neutral to litmus. Run into test-tubes, putting 10 c.c. into each tube. Sterilise. When required for use, melt in water-bath and when at boiling-point run in 1*5 c.c. of neutral litmus solution and 0*92 c.c. of deci-normal alkali. The medium should now have an alkalinity equal to 8 per cent, of deci-normal alkali. B. coli colonies on plates of this medium show a rose-red colour, while those of B. typhosus are translucent blue points. TABLE OF LOG. r FUNCTIONS. {See page 818.)
