[Immunochemotherapy of infants in the first year of life with intestinal infections due to opportunistic gram-negative aerobic bacteria]. 
The clinical and microbiological observations of 50 babies of the 1st year of age with intestinal infections due to opportunistic organisms were made.  The babies were treated with antibacterial drugs and an immunoglobulin preparation.  It was shown that the combined use of antibacterial and immunological preparations in the treatment of the babies with the intestinal infections caused by opportunistic organisms provided their earlier clinical recovery and lowered the unfavourable effect of the antibacterial drugs on the intestinal microflora.
