The antibacterial effects of 24-h exposures to high-pressure oxygen in relation to environmental CO(2) were studied at 3 atm absolute (ata) and at 1 ata. Eight gram-negative, aerobic and facultatively aerobic, pathogenic enteric bacteria (Salmonella typhosa, Salmonella paratyphi, Salmonella schottmuelleri, Shigella dysenteriae, Shigella flexneri, Proteus vulgaris, Pseudomonas aeruginosa, and Es...

A wide range of parts of the medicinal plant is used for extract as raw drugs and they possess varied medicinal properties. The different parts are used include root, stem, flower, fruit, twigs exudates and modified plant organs. One of the greatest accomplishments of modern medicine has been the development of antimicrobials for the treatment of infectious diseases. Microbial diseases remain a...

Gram-negative rods have assumed a major role in infectious disease, particularly among hospitalized patients. Among the Enterobacteriaceae, members of the genus Proteus may cause infections of the urinary' and respiratory2 tracts, as well as meningitis,8 soft tissue infections,' and septicemia.' However, mere isolation of these bacteria did not necessarily indicate the presence of infection. Th...

The in vitro activity of sparfloxacin, a new quinolone, was compared with those of ciprofloxacin and fleroxacin against gram-positive and gram-negative bacteria, greater than 90% of which were isolated from blood culture specimens of cancer patients. Sparfloxacin was extremely active against Acinetobacter species, Aeromonas hydrophila, Citrobacter diversus, Enterobacter species, Escherichia col...

INTRODUCTION Gram-negative bacteria of genus Proteus are common human intestinal and urinary tract pathogens. In the genus Proteus there are four clinically important named species: P. mirabilis, P. vulgaris, P. penneri, and P. hauseri, and three unnamed Proteus genomospecies: 4, 5, and 6. The clinical significance of P. penneri, described in 1982 as a new species, is poorly documented. The aim...

The in vitro activity and beta-lactamase stability of ceftazidime were evaluated against 700 gram-positive and gram-negative bacteria. Ceftazidime was less active than penicillins or older cephalosporins against Staphylococcus spp. and Streptococcus spp., and it did not inhibit Streptococcus faecalis, Listeria, or anaerobic species. Ceftazidime was as active as ceftizoxime and moxalactam and mo...

BACKGROUND The magnitude of food-borne illnesses in India is unknown because of lack of surveillance networks. Monitoring the prevalence of food-borne pathogens and indicators of contamination in primary production at abattoirs is imperative for creating a data bank and for effective control of such pathogens before they enter the food chain. METHODOLOGY Microorganisms of hygienic interest we...

BACKGROUND Proteus spp. bacilli belong to opportunistic human pathogens, which are primarily responsible for urinary tract and wound infections. An important virulence factor is their ability to form biofilms that greatly reduce the effectiveness of antibiotics in the site of infection. OBJECTIVES The aim of this study was to determine the value of the minimum concentration of ciprofloxacin t...

Phyllanthus wightianus belongs to Euphorbiaceae family having ethnobotanical importance. The present study deals with validating the antimicrobial potential of solvent leaf extracts of P. wightianus. 11 human bacterial pathogens (Bacillus subtilis, Streptococcus pneumoniae, Staphylococcus epidermidis, Proteus vulgaris, Pseudomonas aeruginosa, Klebsiella pneumoniae, Salmonella typhimurium, Esche...

The diversity of some of the culturable microorganisms associated with marine flora and fauna collected off Vizhinjam and Mulloor coast of South India was evaluated and their bioactive production potential determined. From a total of 24 bacteria, 4 actinomycetes and 8 fungi isolated from diverse marine sources, five bacterial species-BLM3, BSP2, BCS1, BCS4 and BMA6 showed inhibitory activity ag...
