Staphylococcus aureus and Mesophilic Aerobic Bacteria Quantification in Hygienization Process of Milking Equipment

Polysaccharides synthesized by aerobic mesophilic spore-forming bacteria.

In the classification proposed by Smith, Gordon & Clark (1946) the genus Bacillus has been divided into three groups depending principally on morphological differences in the size and shape of the spores and the shape of the sporangia. Their classification and nomenclature has been used throughout this paper. The bacilli of group I are known to synthesize fructosans from sucrose; those obtained...

Effects of combination of magnesium and zinc oxide nanoparticles and heat on Escherichia coli and Staphylococcus aureus bacteria in milk

Objective: The objective of this study was to investigate the antibacterial activities of combination of MgO and ZnO nanoparticles in the presence of heat against Escherichia coli and Staphylococcus aureus. Materials and Methods:Bacteria were grown on either agar or broth media followed by the addition of ZnO and MgO nanoparticles. Then the combined effect of ZnO and MgO nanoparticles was inves...

Aerobic respiratory metabolism of Staphylococcus aureus from an infected animal.

Gellenbeck, S. Mercy (Catholic University, Washington, D. C.). Aerobic respiratory metabolism of Staphylococcus aureus from an infected animal. J. Bacteriol. 83:450-455. 1962.-The separation of Staphylococcus aureus from the tissue fluids of an infected guinea pig has allowed a comparison of cells (GPR) separated in this manner with the same strain (PR847) grown on an artificial medium. In gene...

Peptide signaling in Staphylococcus aureus and other Gram-positive bacteria.

There are two basic types of bacterial communication systems--those in which the signal is directed solely at other organisms and those in which the signal is sensed by the producing organism as well. The former are involved primarily in conjugation; the latter in adaptation to the environment. Gram-positive bacteria use small peptides for both types of signaling, whereas Gram-negative bacteria...
