In ascending order, the relative activities (% susceptible) were penicillin (51.8%), trimethoprim/sulfamethoxazole (TMP/SMX) (57.6%), erythromycin (59.5%), cefuroxime (62.0%), amoxicillin/clavulanate (85.5%), clindamycin (86.1%), levofloxacin (99.4%), and linezolid (100%; for 2004 and 2005 respiratory seasons, only). Resistance rates over the 5 years remained generally stable, although resistance to amoxicillin/clavulanate nearly doubled (from 6.5% to 12.9%). Forty percent of isolates were resistant to >or=2 agents tested.

We present the case of a 51-y-old male with multiple splenic abscesses that failed to resolve despite antimicrobial therapy targeted at Burkholderia pseudomallei. Elective splenectomy was performed to clarify the diagnosis. Pus from the spleen was subjected to universal bacterial 16S rDNA amplification and sequencing. The sequence obtained was 99% identical to 16S rDNA sequences for Burkholderia pseudomallei. Sequencing of the 16S rDNA is a very promising diagnostic tool allowing quick identification of Burkholderia pseudomallei directly from clinical specimen.

MICs of 10 oral antibiotics were determined for 105 Moraxella catarrhalis and 96 Haemophilus influenzae isolates from adults. A two- to fourfold increase in MICs of oral cephalosporins was seen in the presence of BRO-1 but not with TEM-1 or BRO-2. The MICs of cefixime for 90% of strains of H. influenzae (0.125 microgram/ml) and M. catarrhalis (0.25 microgram/ml) were 8- to 64-fold lower than those of other oral cephalosporins.

This study aimed at making local antibiotic therapy wider in cases of chronic suppurations by administering antibiotics which previously could not be given in this way through the conventional polymethylmetacrylate (PMMA) carrier techniques. Capsules from this material were produced with a pressing machine designed and laid out by us. The characteristics of antibiotic penetration from this novel carrier were compared to those of PMMA beads.

In July 2009, a 53-year-old white woman (weighing 85 kg) affected by psoriasis and psoriatic arthritis was administered infliximab (5 mg/kg IV), based upon clinical appearance and previous unsuccessful treatment with cyclosporine, methotrexate, etanercept, and adalimumab. Three days after the first 3 infusions (at weeks 0, 2, and 6) she complained about the recurrent onset of painful, erythematous, indurated, and pus-draining cutaneous nodules located on her abdomen. The swab always revealed the presence of MSSA, and antibiotic oral therapy with amoxicillin + clavulanic acid (875 + 125 mg BID for 7 days) was established, with complete resolution of the abscesses. Routine laboratory findings were in normal ranges, with the exception of an elevated erythrosedimentation rate and an increased white blood cell count (range, 13,000-15,000/mm(3)) with neutrophilia (range, 75%-80%). HIV infection was ruled out. In agreement with the infectious disease consultant, 1 day before the fourth infusion, a prophylactic antibiotic therapy with amoxicillin + clavulanic acid (875 + 125 mg BID for 5 days) was added to the therapeutic regimen. This treatment schedule was successfully repeated at each following infusion (every 8 weeks), and no recurrence of skin abscesses was observed. The patient provided signed authorization for publication of this case.

In a retrospective study, the clinical and microbiological efficacy of amoxycillin-clavulanic acid and ciprofloxacin were evaluated in outpatients observed within the previous year who were affected by acute purulent exacerbations of chronic bronchitis. Of the 95 patients included in the trial, 50 received amoxycillin 875 mg-clavulanic acid 125 mg 8-hourly for 10 days and 45 received ciprofloxacin 500 mg 12-hourly before meals for 10 days. Of the amoxycillin-clavulanic acid-treated patients, 90% showed clear clinical improvement and in 10% treatment failed. In the ciprofloxacin group, 75.5% of patients showed improvement and in 24.5% treatment failed. All pathogens isolated prior to therapy were susceptible to the antibiotic used for therapy. At the end of treatment, in the amoxycillin-clavulanic acid-treated group, 84% of strains were eradicated and 8% persisted; others were superinfections. In the ciprofloxacin group, 57.7% of strains were eradicated, 26.6% persisted and 15.5% were superinfections. No clinically significant side effects were observed in either group. Overall, amoxycillin-clavulanic acid demonstrated superior clinical and microbiological efficacy to ciprofloxacin, although this might be attributable to the higher proportion of aerobic Gram-negative pathogens in the ciprofloxacin group.
