BACKGROUND The diagnosis of aortitis is often delayed as symptoms are largely non-specific. We report a case of Staphylococcal thoracic aortitis in a 73-year-old Chinese woman complicated by aortic dissection. METHODS The patient presented with pyrexia of unknown origin, and a contrast enhanced computed tomography aortogram revealed a large thrombus at the anterior aspect of the ascending aor...

More than 500 clinical isolates were screened for resistance to a number of antibiotics, including imipemide (N-formimidoyl thienamycin [MK0787]). Of the 25 coagulase-negative staphylococcal isolates present in the screening sample, almost one-third showed one of two patterns of imipemide resistance. One pattern apparently involves constitutive expression of drug resistance, whereas the other p...

The clinical and laboratory characteristics of 38 staphylococcal adult bacterial meningitis (ABM) cases (19 Staphylococcus aureus infections and 19 coagulase-negative staphylococcal [CoNS] infections), collected over a period of 6.5 years (July 1999-December 2005; total ABM cases=181) were analyzed. The results were compared with those of our previous study (January 1986-June 1999; total ABM ca...

Production of staphylococcal alpha- or alpha-beta-toxins correlated well with production of coagulase or thermonuclease (or both) in 203 Staphylococcus aureus isolates from milk and should be reliable indicators of S. aureus in the absence of Staphylococcus intermedius. Failures to produce toxin, tube coagulase, or thermonuclease occurred in only 1 to 2% of S. aureus. Evidence of beta- or alpha...

Skalka B.: Antagonistic Effect of Staphylococcus hyicus and Staphylococcus chromogenes Exhibited on Staphylococcal Delta Hemolysin. Acta vet. Bmo, 60,1991: 61-69. Staphylococcus hyicus and Staphylococcus chromo genes are able to inhibit hemolytic effect of the staphylococcal delta hemolysin on agar media supplemented with human or sheep erythrocytes. This inhibition takes place even when the ef...

The Staphylococcus aureus bacteriophage phi11 endolysin has two peptidoglycan hydrolase domains (endopeptidase and amidase) and an SH3b cell wall-binding domain. In turbidity reduction assays, the purified protein can lyse untreated staphylococcal mastitis pathogens, Staphylococcus aureus and coagulase-negative staphylococci (Staphylococcus chronogenes, Staphylococcus epidermidis, Staphylococcu...

Staphylococcal food poisoning (SFP) caused by enterotoxigenic staphylococci is one of the main food-borne diseases. In contrast to Staphylococcus aureus, a systematic screening for the enterotoxins has not yet been performed on the genomic level for the coagulase-positive species S. intermedius. Therefore, the enterotoxigenic potential of 281 different veterinary (canine, n = 247; equine, n = 2...

important staphylococcal characteristics such as hemolysin and coagulase production will become available for analysis, either directly through selection or by means of linkage to other selectable markers. More details of the above and the results of further experiments will be reported elsewhere. Summary.-Genetic transduction by staphylococcal bacteriophage has been demonstrated. About one pha...
