Abstract
A method of preparing a solution of lactic or colostric immunoglobulins or both by processing milk or colostrum or both accompanied by precipitation of the caseins, characterized in that milk or colostrum or both are acidified to a pH of 4.0-5.5, subjected to cross-flow filtration in a filtration unit with a mean pore size of 0.1-1.2 .mu.m, and the low-molecular components removed by means of further cross-flow filtration in another filtration unit with a limit of separation of 5 000-80 000 daltons, as well as an agent for treating bacterial and viral infections that consists of a solution obtained by means of said method.

In the preparation of a solution of lactic or colostric immunoglobulins by processing a lactic and/or colostric milk and precipitating the caseins, the improvement which comprises acidifying the milk to a pH of 4.0-5.5, subjecting the milk to cross-flow filtration in a filtration unit with a mean pore size of 0.1-1.2 .mu.m, and subjecting the filtrate to a further cross-flow filtration in another filtration unit with a limit of separation of 5,000-80,000 daltons, thereby to separate the low-molecular components therefrom.
