Antibacterial Milk Product
Antibacterial milk, from which various antibacterial milk products can be extracted, can be produced in accordance with the process set forth in U.S. Reissue Pat. No. Re. 33,565, the disclosure of which is hereby incorporated by reference. A synopsis of the process, as described in U.S. Reissue Pat. No. Re. 33,565, is provided below.
Preparation of the Vaccine
The bacteria strains listed in Table One, obtained from the American Type Culture Collection, are individually grown on a blood agar plate to test the viability of the culture and determine if growth pattern is typical or atypical of the bacteria in question. A single colony from each of the test cultures is taken for histological examination to further ensure authenticity and purity of the culture. A single colony of each culture is used to inoculate 500 ml of standard culture broth as recommended by the American Type Culture Collection.

All organisms are incubated as static cultures with the exception of Escherichia coli, Salmonella enteritdis, Pseudomonas aeruginosa and Salmonella typhimurium, which are incubated in a shaker to provide agitation. Identification of bacterial strains and the American Type Culture Collection catalog numbers are shown in Table One. Each culture is cultivated for 48 hours at 37oC. Following incubation, the cultures are killed by heating at 60oC. for two hours. Samples of the killed bacteria are used to inoculate fresh broth, which is then incubated for 24 hours at 37oC. to confirm that the killing process was complete. Only cultures proven sterile by this procedure are used for further processing. Sterile cultures are washed five times in distilled water and the cells recovered by centrifugation. The bacterial cells are frozen by immersion in liquid nitrogen and freeze-dried by lyophilization. The lyophilized cells are stored in sterile vials until used for production of the polyvalent vaccine.
A polyvalent vaccine is prepared by weighing out one gram quantities of each of the bacterial strains. The dry cells were mixed together and this mixture is suspended in sterile physiological saline (20 grams of bacteria per 500 ml saline).
A sample of the concentrated solution is diluted in serial fashion with saline to determine the dilution, which gives a concentration of 4x108 CL per cc. The stock concentrated polyvalent vaccine is dispersed into multiple containers and stored frozen. A sufficient amount of concentrated antigen is included in each individual container to immunize 50 cows. The final dilution of concentrate is made just prior to immunization. The preferred procedure is to remove a sufficient number of vials to immunize the number of cows to be treated. For example, the vials are removed 24 hours prior to the planned time of immunization; a sample of the concentrate is then diluted in a sterile container to a final concentration of 4x108 cells per ml. The maximum response in cows is obtained by injecting 20x108 bacterial cells or 5 cc of the sterile preparation, which is 4x108 cells per ml according to the method on immunization described below.
Preferred Process for Immunization of Cows
Cows are injected with 5 cc of polyvalent antigen containing 20x108 bacterial cells. The injection is made intramuscularly in the gluteus maximus muscle of the hind leg. This procedure is repeated at one-week intervals for four consecutive weeks beginning 2-3 weeks prior to the predicted day of parturition. Following the primary immunization, booster injections using the same concentration of the antigen are given every 14 days. This method of immunization gives the maximum antibody titer.
Collection, Handling and Processing of Milk
The milk is collected from immunized cows in a modern dairy parlor. A fully automated milking system collects and stores the milk under complete sanitary conditions. The milking system consists of automated machines connected directly to refrigerated storage tanks by a closed system of pipes. The complete system is cleaned and sterilized following each milking to ensure maximum sanitary conditions. It is important to take careful steps to prevent the growth of bacteria in the antibacterial milk during processing, since such bacteria can lower the concentration of proteins in the milk.
Milk is transported daily from the refrigerated holding tanks to a dairy processing plant by milk transport trucks. At the dairy plant, a high temperature short-time system is used to pasteurize the antibacterial milk. Specialized dairy machinery provides the flash heating of a continuous flow of milk to 155oF. for a period of not more than 15 seconds. Temperature and time is critical since proteins are susceptible to degradation by heat. Milk proteins are destroyed at temperature above 165oF. if held for periods longer than one minute.
Following pasteurization, the whole milk is immediately cooled, fat is removed by centrifugation to produce skimmed antibacterial milk, and the skimmed antibacterial milk is powdered by a spray-drying process. The spray-drying process consists of a large drying chamber into which hot air (350oF.) is blown at high velocity. The skimmed milk is atomized into the chamber where the finely divided milk particle are instantly dried as they fall to the bottom of the tank. The dried milk is removed automatically by means of mechanical devices and the milk powder is packaged under sanitary conditions. Prior to atomizing, the skimmed milk is condensed by boiling in a chamber under vacuum at a temperature of 100 to 110oF. At each step, it is critical to keep bacteria from contaminating the milk since this reduces the concentration of milk proteins.
Concentration of Milk
A concentrated form of the antibacterial milk in which about 95% of the lactose and salt is removed can be obtained by ultrafiltration of the pasteurized skimmed antibacterial milk through a membrane or molecular sieve that retards molecules with a molecular weight of greater than 100,000 as set forth in U.S. Pat. No. 5,106,618, the disclosure of which is hereby incorporated by reference. Since immunoglobulins have molecular weights well in excess of 100,000 while lactose has a molecular weight well below 100,000, lactose is effectively separated from the immunoglobulin milk proteins. This permits a 10 to 100 fold concentration, typically about a 30 fold concentration, of the milk proteins.
Such concentration of the antibacterial milk reduces the mass to such an extent that capsules containing an effective amount of the milk proteins can be formulated from concentrated antibacterial powdered skimmed milk.
Commercial Availability of Antibacterial Milk Products Concentrated antibacterial powdered skimmed milk, manufactured in accordance with the process described above and useful in the treatment of menorrhagia, hypermenorrhea, dysmenorrhea and menstrual migraines in accordance with the treatment method disclosed herein, is commercially available from AdvantRx Corporation of Chanhassen, Minnesota and Stolle Milk Biologics, Inc. of Cincinnati, Ohio under the mark MicroLactin.TM..
