Survivorship of Salmonella typhimurium, Streptococcus faecalis, Proteus mirabilis, and Pseudomonas aeruginosa was studied in dibiotic and tribiotic interactions in vitro and in various regions of the digestive tract of the blow fly, Calliphora vicina. In dibiotic interactions, Salmonella typhimurium dominated Streptococcus faecalis and was dominated by P. mirabilis, but in neither case was it e...

Polymicrobial infections involving Staphylococcus aureus exhibit enhanced disease severity and morbidity. We reviewed the nature of polymicrobial interactions between S. aureus and other bacterial, fungal, and viral cocolonizers. Microbes that were frequently recovered from the infection site with S. aureus are Haemophilus influenzae, Enterococcus faecalis, Pseudomonas aeruginosa, Streptococcus...

The HPr proteins of Streptococcus lactis, Streptococcus faecalis, Bacillus subtilis, and Escherichia coli were studied by 1H NMR at 360 MHz. The "active-center" histidines of all HPr proteins are characterized by a low pK value between 5.6 and 6.1 and similar spectral parameters. Phosphorylation of the histidyl residues leads to an increase of the pK value of 2-3 units and spectral changes char...

Streptococci of Lancefield group D were isolated from 52.2% of pharyngeal, 55.5% of urethral, 56.6% of endocervical, and 75.4% of ano-rectal specimens. Seventeen phages isolated from sewage and urogenital specimens were selected for phage typing. Four of these lysed only the strains of Streptococcus faecalis and its variety liquefaciens. Another six phages lysed only the strains of Streptococcu...

The susceptibilities of 12 strains of enterococci and 10 stains of Listeria monocytogenes to N-formimidoyl thienamycin were determined by a standard broth dilution method. Minimal inhibitory concentrations for L. monocytogenes strains were less than 0.25 micrograms/ml. As a group, strains of Streptococcus faecium were less susceptible than Streptococcus faecalis strains, but even for the latter...

Introduction: Enterococci represent the third most common cause of infective endocarditis, after streptococcus and Staphylococcus aureus, and are responsible for 5–20% of all cases of endocarditis. We present a rare case of native valve Enterococcus faecalis (E. faecalis) endocarditis of mitral valve in a breast cancer patient. Case Report: A 56­year­old breast cancer patient presented with com...

Daptomycin is a lipopeptide antibiotic with activity against Gram-positive bacteria. We showed previously that Staphylococcus aureus can survive daptomycin exposure by releasing membrane phospholipids that inactivate the antibiotic. To determine whether other pathogens possess this defence mechanism, phospholipid release and daptomycin activity were measured after incubation of Staphylococcus e...

The reduction of 2, 3, 5 triphenyltetrazolium chloride in the original medium of Barnes (Journal of General Microbiology, 14, 57, 1956), and in a modified medium, was compared with the ability to ferment pyruvate as a means of separating Streptococcus faecalis from all other group D streptococci. The tetrazolium reduction test gave an occasional negative reaction with Str. faecalis strains. In ...
