IT is just twenty-nine years since the discovery of penicillin and sixteen years since it w,as first used as a therapeutic substance. Penicillin, the first antibiotic, was the forerunner of some thousands of antibiotic substances, only a small fraction of which have provred to be of therapeutic value. One of the main reasons for this was the toxicity of many of the substances and their tendency...

The rates of post-operative endophthalmitis have been low for many years, but recent reports suggest that this type of ocular infection may be on the rise. Fluctuations in the number of cases appear to correlate with the type of intraocular surgery performed. Post-operative endophthalmitis has been reported as a consequence of nearly every type of ocular surgery, but is most common following ca...

Amoxycillin was significantly more active than ampicillin in the treatment of intraperitoneal mouse infections when administered by oral and parenteral routes, although the causal bacteria were equally susceptible in vitro to the two penicillins. Amoxycillin produced higher antibiotic blood concentrations in mice than ampicillin after oral administration, and this was a possible explanation for...

The biliary elimination of mezlocillin, a new semisynthetic penicillin of the acyl-ureido-penicillin group, was investigated in vitro in rabbit liver preparations and in vivo in humans. Experimentally, mezlocillin recovery in the bile during perfusion of isolted rabbit liver (3 h; n = 5) averaged 20.3% of the administrered dose (10 mg). The mean peak concentration in the bile (758 +/- 129.3 mic...

Multiple-injection affinity capillary electrophoresis (MIACE) was used to determine binding constants (K(b)) between vancomycin, ristocetin, and teicoplanin from Streptomyces orientalis, Nocardia lurida, and Actinoplanes teichomyceticus, respectively, and fluorenylmethoxycarbonyl (Fmoc)-(Gly, Ala, Val, and Phe)-D-Ala-D-Ala peptides. In this technique, separate plugs of sample containing non-int...

BACKGROUND While the importance of fluid dynamical conditions is well recognized in the growth of biofilms, their role during bacteremia is unknown. We examined the impact of physiological fluid shear forces on the development of multicellular aggregates of Klebsiella pneumoniae. METHODS Wild-type and O-antigen or capsular mutants of K. pneumoniae were grown as broth culture in a Taylor-Couet...

Most epidural abscesses are a secondary lesion of pyogenic spondylodiscitis. An epidural abscess associated with pyogenic arthritis of the facet joint is quite rare. To the best of our knowledge, there is no report of the use of antibiotic-cement beads in the surgical treatment of an epidural abscess. This paper reports a 63-year-old male who sustained a 1-week history of radiating pain to both...
