Clin Diagn Lab Immunol
. 2001 Mar;
8(2):363-9.
PMID: 11238223
Host protection against Streptococcus pneumoniae is mainly mediated by opsonin-dependent phagocytosis. Several techniques for measuring opsonophagocytic activity (OPA) of antibodies to S. pneumoniae have been standardized and used. These include...

. 2001 Jan;
90(1):59-67.
PMID: 11155123
Combinations of lactococcal strains from various origins with divers properties were developed as new starters for new dairy products. Flavour formation by such tailor-made cultures was studied. In some cases,...

PMID: 9871325
Exogenously provided carnitine (beta-hydroxy-L-tau-N-trimethyl aminobutyrate) was found to stimulate aerobic growth of enterohaemorrhagic Escherichia coli O157:H7 in a medium of inhibitory osmotic strength. Its osmoprotective ability is comparable with that...

. 1998 Mar;
64(3):1059-65.
PMID: 9501445
For effective utilization of peptides, Listeria monocytogenes possesses two different peptide transport systems. The first one is the previously described proton motive force (PMF)-driven di- and tripeptide transport system (A....

179(22):6979-85.
PMID: 9371443
The naturally occurring compatible solutes betaine and L-carnitine allow the food-borne pathogen Listeria monocytogenes to adjust to environments of high osmotic strength. Previously, it was demonstrated that L. monocytogenes possesses...

PMID: 9293015
The natural variation in the susceptibilities of gram-positive bacteria towards the bacteriocins nisin and pediocin PA-1 is considerable. This study addresses the factors associated with this variability for closely related...

PMID: 9055431
The inhibitory effect of the cationic peptide protamine on Listeria monocytogenes, Escherichia coli, and Shewanella putrefaciens has been studied in detail. The addition of protamine (10 to 1,000 micrograms/ml) resulted...
