Non-duplicate cultures of S. pneumoniae were collected from 1 January to 31 December 2002 in the three penicillin-susceptibility categories. Minimum inhibitory concentrations (MICs) of 19 antibacterial agents were determined by agar dilution based on the National Committee for Clinical Laboratory Standards (NCCLS) methodology. Overall for 2002, 687 non-duplicate isolates were obtained, of which 190 (28%) were intermediate or resistant to penicillin. From this set, 183 isolates were selected for study: 88 (48%) in the penicillin-susceptible group (MIC or= 2.0 mg/L).

The effects of yoghurt on the pharmacokinetics of moxitloxacin are considered not clinically relevant. Hence, no special recommendations for administration are required when moxifloxacin is given together with dairy products.
Moxifloxacin significantly reduced time to recovery from AE-COPD in patients with moderate to severe disease by approximately 20% (>1 day) compared with other antimicrobials. Faster recovery should result in earlier return to work or normal activities, and to social and economic savings.

We used 2 types of strains, ie, American Type Culture Collection strains and resistant strains. The former included Staphylococcus aureus, coagulase-negative staphylococci, Pseudomonas aeruginosa, and Serratia marcescens, The latter were methicillin-resistant Staphylococcus aureus; methicillin-resistant, coagulase-negative Staphylococcus sp.; and ciprofloxacin-resistant P. aeruginosa. The HCECs were incubated with each bacterial population for 1 hour and exposed to both antibiotics for 1 hour. The colony-forming units of viable bacteria per well were expressed as base 10 logarithms. To determine corneal epithelial toxicity, we exposed the HCECs to each antibiotic agent, and the viable epithelial cells were quantified by the MTT assay. We also observed the wound healing rate of injured HCECs cultured in each antibiotic agent for 24 hours.

Actinomyces meyeri was predominantly isolated and accounted for 34% of all Actinomyces spp. identified, followed by Actinomyces turicensis with 23%. Actinomyces neuii is considered to be a rare Actinomyces sp., but accounted for 8% of isolates. Antimicrobial susceptibility testing of isolates showed that the Actinomyces spp. were almost uniformly susceptible to β-lactam antimicrobials (with and without β-lactamase inhibitors), carbapenems, tetracyclines and vancomycin. In contrast, Actinomyces spp. isolates were almost uniformly resistant to metronidazole.
avelox generic introduction
Mutations in the DNA gyrase GyrA2GyrB2 complex are associated with resistance to quinolones in Mycobacterium tuberculosis. As fluoroquinolones are being used increasingly in the treatment of tuberculosis, we characterized several multidrug-resistant clinical isolates of M. tuberculosis carrying mutations in the genes encoding the GyrA or GyrB subunits associated with quinolone resistance or hypersusceptibility. In addition to the reported putative quinolone resistance mutations in GyrA, i.e., A90V, D94G, and D94H, we found that the GyrB N510D mutation was also associated with ofloxacin resistance. Surprisingly, several isolates bearing a novel combination of gyrA T80A and A90G changes were hypersusceptible to ofloxacin. M. tuberculosis GyrA and GyrB subunits (wild type [WT] and mutants) were overexpressed in Escherichia coli, purified to homogeneity, and used to reconstitute highly active gyrase complexes. Mutant proteins were produced similarly from engineered gyrA and gyrB alleles by mutagenesis. MICs, enzyme inhibition, and drug-induced DNA cleavage were determined for moxifloxacin, gatifloxacin, ofloxacin, levofloxacin, and enoxacin. Mutant gyrase complexes bearing GyrA A90V, D94G, and D94H and GyrB N510D were resistant to quinolone inhibition (MICs and 50% inhibitory concentrations [IC50s] at least 3.5-fold higher than the concentrations for the WT), and all, except the GyrB mutant, were less efficiently trapped as a quinolone cleavage complex. In marked contrast, gyrase complexes bearing GyrA T80A or A90G were hypersusceptible to the action of many quinolones, an effect that was reinforced for complexes bearing both mutations (MICs and IC50s up to 14-fold lower than the values for the WT). This is the first detailed enzymatic analysis of hypersusceptibility and resistance in M. tuberculosis.

Women from hospitals throughout 13 countries received a 14 day course of either oral moxifloxacin, 400 mg once daily (n = 384), or oral ofloxacin, 400 mg twice daily plus oral metronidazole, 500 mg twice daily (n = 365).
This was a single-dose, randomized, placebo- and active-controlled, 4-way crossover study in healthy subjects. Subjects were randomly allocated to 1 of 4 different administration sequences. Each sequence included 3 double-blind treatments (levetirace-tam 1000 mg, levetiracetam 5000 mg, and placebo) and 1 open-label treatment (moxifloxacin 400 mg). Triplicate electrocardiograms (ECGs) were obtained at baseline and at various time points over 24 hours after each treatment using continuous Holter monitoring. ECGs were read centrally in a blinded manner. Blood samples for the determination of plasma concentrations of levetiracetam and moxifloxacin were collected before dosing and at 0.5, 1, 1.5, 2, 4, 6, 12, and 24 hours after dosing, within 5 minutes after the ECG recordings. The QT interval was corrected for heart rate using a sex- and study-specific correction (QTc(ss)) as the primary outcome measure and Fridericia's correction (QTc(F))as a secondary outcome measure. The primary analysis was performed on the time-matched, baseline-subtracted QTc(ss) (DeltaQTc(ss)). The maximum DeltaQTc(ss) difference between each active treatment and placebo (DeltaDeltaTc(ss)) was derived from a mixed-effect analysis of variance. Clinical laboratory tests, standard 12-lead ECGs, and vital signs were monitored at regular intervals. Spontaneously reported adverse events were recorded throughout the study.

We assess the effect of topical corticosteroids (vs placebo) on 3-month best spectacle-corrected visual acuity in patients who received corticosteroids or placebo earlier vs later. Further analyses were performed for subgroups of patients with non-Nocardia keratitis and those with no topical antibiotic use before enrollment.
The categorical agreement among MIC results for the fluoroquinolones tested (levofloxacin, moxifloxacin, gatifloxacin and gemifloxacin) was high (99.16-99.85%), and error rates were nil or very low when 1 compound was used as a surrogate for predicting susceptibility (not resistance) to another agent in the class. No error was observed when levofloxacin was selected as the group surrogate for pneumococcal testing.

Isolates of S. pneumoniae from three patients were exposed to selected ophthalmic antibiotic products: moxifloxacin 0.5%, tobramycin 0.3%, gentamicin 0.3%, and polymyxin B 10,000 IU-trimethoprim 1.0%. The products were diluted 1:100 and 1:1000 for testing. At 15, 30, 60, 120, and 180 minutes after exposure, aliquots of broth were withdrawn, the cells were separated and cultured, and the viable cell count was determined.

Four-hundred stool specimens were collected from the diarrheic and non-diarrheic pediatrics hospitalized due to the diseases other than diarrhea. Samples were cultured and their positive results were subjected to disk diffusion and PCR-based ribotyping.
The cost-effectiveness ratio for intracameral cefuroxime is $1403 per case of postoperative endophthalmitis prevented. By comparison, the least expensive topical fluoroquinolone in our study, ciprofloxacin, would have to be >8 times more effective than intracameral cefuroxime to achieve cost-effective equivalence. The most expensive topical fluoroquinolones studied, gatifloxacin and moxifloxacin, would have to be > or =19 times more effective than intracameral cefuroxime to achieve cost-effective equivalence. A sensitivity analysis reveals that even in the worst case scenario for intracameral cefuroxime efficacy and with a 50% reduction in the cost of 4th-generation fluoroquinolones, gatifloxacin and moxifloxacin would have to be > or =9 times more effective than intracameral cefuroxime to achieve cost-effective equivalence.

In an open, randomized, six-period crossover study, the pharmacokinetics of ciprofloxacin, gatifloxacin, grepafloxacin, levofloxacin, moxifloxacin, and trovafloxacin were compared after a single oral dose in 12 healthy volunteers (6 men and 6 women). The volunteers received 250 mg of ciprofloxacin, 400 mg of gatifloxacin, 600 mg of grepafloxacin, 500 mg of levofloxacin, 400 mg of moxifloxacin, and 200 mg of trovafloxacin. The concentrations of the six fluoroquinolones in serum and urine were measured by a validated high-performance liquid chromatography method. Blood and urine samples were collected before and at different time points up to 48 h after medication. Levofloxacin had the highest peak concentration (C(max), in micrograms per milliliter) (6.21+/-1.34), followed by moxifloxacin (4.34+/-1.61) and gatifloxacin (3.42+/-0.74). Elimination half-lives ranged from 12.12+/-3.93 h (grepafloxacin) to 5.37+/-0.82 h (ciprofloxacin). The total areas under the curve (AUC(tot), in microgram-hours per milliliter) for levofloxacin (44.8+/-4.4), moxifloxacin (39.3+/-5.35), and gatifloxacin (30+/-3.8) were significantly higher than that for ciprofloxacin (5.75+/-1.25). Calculated from a normalized dose of 200 mg, the highest C(max)s (in micrograms per milliliter) were observed for levofloxacin (2.48 +/-0.53), followed by moxifloxacin (2.17+/-0.81) and trovafloxacin (2.09+/-0.58). The highest AUC(tot) (in microgram-hours per milliliter) for a 200-mg dose were observed for moxifloxacin (19.7+/-2.67) and trovafloxacin (19.5+/-3.1); the lowest was observed for ciprofloxacin (4.6+/-1.0). No serious adverse event was observed during the study period. The five recently developed fluoroquinolones (gatifloxacin, grepafloxacin, levofloxacin, moxifloxacin, and trovafloxacin) showed greater bioavailability, longer half-lives, and higher C(max)s than ciprofloxacin.

The incidence of C. difficile-associated diarrhea peaked at 21 cases per 1,000 patient admissions. Of the C. difficile isolates recovered, 85 (95%) were identical toxin A-negative and toxin B-positive strains, corresponding to toxinotype VIII and PCR ribotype 017. All clonal isolates were resistant to multiple antibiotics, including ofloxacin, ciprofloxacin, levofloxacin, moxifloxacin, and gatifloxacin (minimum inhibitory concentrations [MICs] of greater than 32 micro g/mL) and erythromycin, clarithromycin, and clindamycin (MICs of greater than 256 micro g/mL). Recurrent C. difficile-associated disease occurred in 26 (36%) of the patients. At least 10 (14%) of the patients developed C. difficile colitis. Additional infection control measures introduced included the use of ward memos, a hand-hygiene awareness campaign, increased environmental cleaning, attention to prescribing practices for antibiotics, increased awareness of diarrheal illness, and early isolation of affected patients. Total use of fluoroquinolones did not change throughout the study period. Despite persistence of this toxin-variant strain, the incidence of C. difficile-associated disease in our institution decreased to fewer than 5 cases per 1,000 admissions.

Screening by ofloxacin disk was carried out on 1158 strains of Streptococcus pneumoniae in order to investigate the in vitro bacteriostatic activity of penicillin G, levofloxacin, moxifloxacin, telithromycin, linezolid, pristinamycin and quinupristin-dalfopristin against ofloxacin-intermediate and -resistant S. pneumoniae strains. It was concluded that these new antimicrobial agents could be useful for the treatment of pneumococcal infections caused by penicillin-sensitive and -resistant S. pneumoniae, and would represent a valid therapeutic option for patients allergic to beta-lactams, should they prove to be potent in vivo.

Moxifloxacin release from a CL into ATS is lower when compared to release into PBS. When mechanical rubbing is introduced, the amount of drugs released is increased.
All 3 drugs remained potent at 4°C for up to 14 days. Fortified tobramycin and moxifloxacin also maintained potency for 14 days at 24 and 35°C. In contrast, fortified vancomycin lost its potency by day 14 at 24°C and by day 7 at 35°C. All in-use antibiotic drops tested were sterile. The results indicate that patients should be cautioned to store vancomycin under refrigerator or at least under cool conditions.
