existence of multiple immunodeterminants in the type-specific capsular substance of group b type ia streptococci.	rabbits immunized with group b, type ia streptococci produce two distinct populations of protective antibodies. evidence is presented indicating that these antibodies are directed against two major immunodeterminants which coexist in the specific type ia antigen. immunochemical data, using purified antibody preparations, indicate that the type substance, a sialic acid polymer consisting of galactose, glucose, glucosamine, and sialic acid, possesses two distinct immunodominant determinants, termi ...	1978	76609

complete versus selective dry cow therapy for mastitis control.	two hundred and thirty-two cows were assigned alternately to complete dry cow therapy (infusion in all quarters on the day of drying off) or selective therapy (infusion in all quarters if a history of mastitis, california mastitis test score of +2 or +3 in any quarter, or if cell counts from bucket milk samples as determined by the membrane filter-deoxyribonucleic acid procedure were above 500,000 cells/ml). a dry cow product containing 10(6) units of procaine penicillin g and 1 g of dihydrostre ...	1978	81843

non-group d streptococcal meningitis misidentified as enterococcal meningitis. diagnostic and therapeutic implications of misdiagnosis by screening microbiology.	two patients had nonhemolytic gram-positive coccal meningitis. both pathogens were initially misidentified as a group d enterococcus by growth in "selective" media, which led to the use of inappropriate and potentially toxic systemic and intrathecal aminoglycosides. careful evaluation of the antibiotic sensitivity data and additional microbiological studies allowed correct identification of the organism. the important diagnostic and therapeutic considerations in differentiating true enterococcal ...	1978	102268
treatment of bacterial endocarditis with vancomycin.	five patients with bacterial endocarditis who were allergic to penicillin were treated successfully with vancomycin. the causative microorganisms were streptococcus bovis, s faecalis, s agalactiae, s intermedius, and staphylococcus aureus. except for the strain of s faecalis, vancomycin was bactericidal against these organisms at easily achievable serum concentrations. to insure a bactericidal serum titer of 1:8 or greater, streptomycin was added in the therapy of the case caused by s faecalis. ...	1978	104623
