The districution of Staphylococcus and Micrococcus species and associated coryneform bacteria, Acinetobacter, Klebsiella, Enterobacter, Bacillus, and Streptomyces on skin was determined during October 1971 from samples collected on persons living in North Carolina and New Jersey. Persistence of these organisms on skin was estimated in temporal studies conducted during the period from June 1971 ...

The aim of the present study was to evaluate the expression of the Mytilus galloprovincialis lysozyme gene in different in vivo stress situations, including injection of bacteria Vibrio splendidus LGP32, Vibrio anguillarum or Micrococcus lysodeikticus, as well as heat shock at 30 degrees C and cold stress at 5 degrees C. Injection of V. splendidus LGP32 resulted in: (i) a general down-regulatio...

The major carotenoid pigment of a psychrotrophic Micrococcus roseus strain was purified to homogeneity from methanol extracts of dried cells by reverse-phase liquid chromatography and was designated P-3. On the basis of the UV-visible, infrared, mass, and 'H nuclear magnetic resonance spectra of P-3, it was identified as bisdehydro-,-carotene-2-carboxylic acid. The pigment interacted with synth...

Bacterial adhesion to inert surfaces is a complex process influenced by environmental conditions. In this work, the influence of growth medium and temperature on the adhesion of Pseudomonas aeruginosa, Serratia marcescens, Staphylococcus aureus, Micrococcus luteus and Listeria monocytogenes to polystyrene surfaces was studied. Most bacteria demonstrated the highest adhesion when cultured in TSY...

Ippu Padang plant (Ammannia octandra L.f.) belongs to the family of Lythraceae, a hardy that can grow height 50 cm. According previous research, leaves contain glycosides, alkaloids, flavonoids and tannins. The presence alkaloid compounds, tannins is predicted have potential as an antifungal agent against fungi antibacterial agent. This research used experimental method. steps included collecti...

Micrococcus luteus (Schroeter) Cohn 1872 es una de las bacterias que se encuentran en el ambiente, sus colonias presentan pigmentación amarillenta. Este pigmento un carotenoide cuyas propiedades varían según ambiente origen o aislamiento. En la actualidad, importante explorar varias fuentes naturales colorantes grado alimenticio y potenciales efectos industria alimentaria, salud humana veterina...

background: recently the role of platelets in the tissue regeneration, wound healing and prevention and control of infections has been reported. we aimed to assess the antimicrobial effect of human platelet concentrate against six bacteria, commonly found in wound and hospital-acquired infections. methods: in vitro susceptibility to samples of 10 random human platelet concentrates was determine...

Abstract Metals and metal oxide-based nanocomposites play a significant role over the control of microbes. In this study, antibacterial activity iron oxide (Fe 2 O 3 ) based on induction furnace (IF) steel slag has been carried out. IF is an industrial by-product generated from secondary manufacturing process various oxides which includes Al (7.89%), MnO (5.06), CaO (1.49%) specifically Fe (14....

Although enzymatic photoreactivation of cyclobutyl pyrimidine dimers in DNA is present in almost all organisms, its presence in placental mammals is controversial. We tested human white blood cells for photolyase by using three defined DNAs (supercoiled pET-2, nonsupercoiled bacteriophage lambda, and a defined-sequence 287-bp oligonucleotide), two dimer-specific endonucleases (T4 endonuclease V...

In this preliminary report we show that a 29 kDa surface protein of Listeria monocytogenes EGD removed from cells with 4 M LiCl has peptidoglycan (murein) hydrolyzing activity, as revealed by zymographic analysis using Bacillus subtilis murein and heat-killed Micrococcus luteus cells casted in the gel. Following two-dimensional electrophoresis, the protein was electroblotted to PVDF membrane an...
