Organisms Staphylococcus aureus

Primary peritonitis generally is caused by a single organism (.Staphylococcus aureus in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) and Escherichia coli in patients with cirrhosis). 

Fig. 6. Pyrolysis mass spectra of two organisms (Staphylococcus aureus and E.coli). The data from PyMS may be displayed as quantitative pyrolysis mass spectra. The abscissa represents the m/z (mass to electric charge) ratio whilst the ordinate contains information on the ion count for any particular m/z value ranging from 51-200. Below 51 m/z, there is no biologically relevant information in the spectra (from [76])...

Specific micro-organisms Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. 

Test Organism Staphylococcus aureus Klebsiella pneumoniae... 

Alcohols, particularly ethanol [64-17-5] and 2-propanol [67-63-9] are important disinfectants and antiseptics. In the aUphatic series of straight-chain alcohols, the antimicrobial activity increases with increasing molecular weight up to a maximum, depending on the organism tested. For Staphylococcus aureus the maximum activity occurs using amyl alcohol [71-41-0], for Salmonella typhosa, octyl alcohol [111-87-5], CgH gO (43) ioT Mycobacterium tuberculosis... 

Sudol uses fractions of coal tar rich in xylenols and ethylphenols. It is much more active and less corrosive than lysol, and remains more active in the presence of organic matter. The phenol coefficients of sudol against Mycobacterium tuberculosis, Staphylococcus aureus, and Pseudomonas aeruginosa are 6.3, 6, and 4, respectively. It also is slowly sporicidal (97). 

Echinomycin (131) has been shown to be an antitumor agent and to have antiviral and antibacterial properties. Its structure elucidation represents a triumph for and mass spectral studies (75JA2497). It has been demonstrated that echinomycin functions by inhibiting RNA synthesis in organisms such as Staphylococcus aureus. Echinomycin, levomycin and actinoleutin are members of the quinoxaline-peptide antibiotic family and all contain one or more quinoxaline rings (67MI21402). 

Susceptible Gram-positive organisms such as Streptococcus pneumoniae and /3-lactamase-negative Staphylococcus aureus. 

The vast majority of conjunctivitis cases are viral in nature. For acute bacterial conjunctivitis, the cause is primarily grampositive organisms.11 The primary pathogens in acute bacterial conjunctivitis are Streptococcus pneumoniae, Staphylococcus aureus, or Haemophilus influenzae.12... 

Bone infarcts or sickling in the periosteum usually is indicated by pain and swelling over an extremity. Osteomyelitis also should be considered. Salmonella species are the most common cause of osteomyelitis in SCD children, followed by Staphylococcus aureus. 27 Select an appropriate antibiotic to cover the suspected organisms empirically. 

Colonization with resistant gram-positive organisms (e.g., methicillin-resistant Staphylococcus aureus)...
