A fatal case of community acquired pneumonia due to Lactobacillus casei ss rhamnosus is reported. Clinicians should be aware of this type of pneumonia.

1 The binding of a series of amide derivatives of methotrexate to Lactobacillus casei dihydrofolate reductase has been studied by inhibition constant measurements and by 'H n.m.r. spectroscopy. 2 Amide modification of the a-carboxylate of methotrexate was found to prevent interaction of the y-carboxylate with the imidazole of His 28. 3 Estimates of the contributions to the binding energy from t...

The adhesion of Lactobacillus rhamnosus GG to human enterocyte-like Caco-2 cells was not inhibited by eight carbohydrates tested, namely N-acetyl-glucosamine, galactose, glucose, fructose, fucose, mannose, methyl-alpha-D-mannopyranoside and sucrose. The degree of hydrophobicity predicted the adhesion of L. rhamnosus GG to Caco-2 cells. L. rhamnosus GG, however, was able to compete with Escheric...

Pharmaceutical probiotics have been used as alternative treatments or preventative therapies for a variety of clinical diseases. The overuse of antibiotics and emergence of multiple-antibiotic resistant pathogens has refocused clinical attention on the field of probiotics. Anaerobic infections which seem to respond well to probiotics are infections which involve the disruption of normal microbi...

The elucidation of the structure of pteroylglutamic acid (PGA) (Lactobacillus casei factor, vitamin B,) has shown that p-aminobenzoic acid (PABA) is a component of the PGA molecule (1). Since earlier work has treated PABA and PGA as distinct growth factors for bacteria (2), it is now necessary to study the relationship in the utilization of these substances by bacteria. It has been shown that m...

Strains of the Lactobacillus casei group have been extensively studied because some are used as probiotics in foods. Conversely, their phages have received much less attention. We analyzed the complete genome sequences of five L. paracasei temperate phages: CL1, CL2, iLp84, iLp1308, and iA2. Only phage iA2 could not replicate in an indicator strain. The genome lengths ranged from 34,155 bp (iA2...

The hypocholesterolemic effects of Lactobacillus acidophilus 43121 (43121) and a mixture of Lactobacillus casei and Bifidobacterium longum (MIX) were studied in hypercholesterolemia-induced pigs. Serum total cholesterol was decreased by supplementation of either 43121 or MIX, although, high-density lipoprotein cholesterol was not changed. The hypocholesterolemic effect of 43121 and MIX was main...
