Motile Aeromonas infections of the foot are caused mostly by post-traumatic incidence, occurring mostly during summer months. Serious complications such as osteomyelitis and amputation can result if the infections go untreated or are inadequately treated. The role of each species of motile Aeromonas in pathogenesis and response to antimicrobial agents is not well understood because of taxonomic uncertainty. As a group, motile Aeromonas respond well to aminoglycosides, second-generation and third-generation cephalosporins, quinolones, and some beta-lactam antibiotics.

Sixty isolates of Enterobacteriaceae resistant to beta-lactam antibiotics were collected over a period of 2 years in Switzerland and screened by hybridization for the carriage of SHV genes. Thirty-four positive strains were found, and their SHV genes were amplified and sequenced. SHV extended-spectrum beta-lactamases (ESBLs) were found: 13 strains contained SHV-2a, 12 harbored SHV-2, and SHV-5 was found twice. Four strains were shown to contain SHV-1. In addition, we report two new SHV variants, termed SHV-11 (non-ESBL) and SHV-12 (ESBL). In spite of the carriage of SHV ESBLs, many strains showed only low resistance to one or more third-generation cephalosporins. In addition, 26 did not transfer the blaSHV gene in mating experiments.

Abstract Background Acute-on-chronic liver failure (ACLF) is characterized by an excessive systemic inflammatory response and organ failure and has high mortality. Bacterial infections (BIs) worsen the clinical course of ACLF and carry a poor prognosis in ACLF patients. The efficacy of third-generation cephalosporins has been challenged in recent years. The aim of this study was to characterize the difference between ACLF patients with and without BIs and to provide a reference for medical intervention. Methods A total of 140 patients with hepatitis B virus-related ACLF (HBV-ACLF) hospitalized at the Department of Infectious Diseases, Huashan Hospital, Fudan University (Shanghai, China) between May 2013 and January 2020 were enrolled. Mann-Whitney U test was used to compare the baseline characteristics of HBV-ACLF patients with and without BIs. Univariate and multivariate analyses were performed to find predictors of BIs. The characteristics of BIs and the role of prophylactic antibiotics were profiled. Results A total of 97 episodes of BIs occurred in patients during the course of HBV-ACLF. Patients with and without BIs differed in clinical characteristics. The incidence of BIs showed a positive correlation with the ACLF grade (P = 0.003) and the clinical course (P = 0.003). The 90-day transplant-free survival of patients with BIs was lower than those without BIs (P < 0.0001). Patients administered prophylactic antibiotics showed a lower incidence of BIs and had a higher transplant-free survival probability than those who did not (P = 0.046). No statistical differences in antibiotic efficacy between third-generation and other antibiotics were observed (P = 0.108). Conclusions BIs affected the clinical course and prognosis of patients with HBV-ACLF. Prophylactic antibiotics were of potential clinical importance in the prevention of BIs and improving the clinical course and prognosis in HBV-ACLF patients. Third-generation cephalosporins were qualified for use in antibiotic prophylaxis.

Objective: The objective of this study was to analyze the pattern of drug utilization in outpatients of orthopedics department from a tertiary care hospital.Material and Methods: In this retrospective study, prescriptions of randomly selected patients attending orthopedics clinic were screened to analyze a number of medicines per prescription. Number and percentages of prescribed medicines were calculated.Results: In this study, 512 patients (male 260 [50.8%] and females 252 [49.2%]) were included in the study. The total number of prescribed medicines was 1562, accounting for 3.1 medicines per patient. A total number of oral, parenteral, and topical medicines were 1375 (88%), 176 (11.3%), and 11 (0.7%), respectively. Nonsteroidal anti-inflammatory agents (NSAIDs), antacid/anti-ulcerants, and antimicrobial agents were 641 (41%), 371 (23.8%), and 102 (6.5%), respectively. A total of 54 (52.9%), 29 (28.4%), 9 (8.8%), 6 (5.9%), 3 (2.9%), and 1 (1%) patients were prescribed fluoroquinolones, beta-lactam antibiotics, metronidazole, trimethoprim plus sulfamethoxazole, macrolides, and doxycycline, respectively. For 371 (23.8%) patients, anti-ulcerant and antiulcer were prescribed, among which ranitidine was the most common prescription [353 (95.1%)]Conclusion: Number of medicines prescribed per patient in orthopedic clinic was 3.1. NSAIDs and antacid/anti-ulcerants were the most commonly prescribed medicines.

Norfloxacin is a quinoline (quinolinecarboxylic acid) that should prove successful in treating infections that currently require hospitalization and intravenous antibiotics. Although a nalidixic acid derivative, it possesses greater antibacterial activity against gram-positive and gram-negative bacteria. Compared with other antimicrobial agents, norfloxacin is more potent than the aminoglycosides, first-, second-, and third-generation cephalosporins, tetracycline, trimethoprim-sulfamethoxazole, carbenicillin, piperacillin, nalidixic acid, oxolinic acid, cinoxacin, and enoxacin. In the clinical studies to date, the side effects of norfloxacin have been minimal, but include nausea, vomiting, anorexia, dizziness, headache, drowsiness, depression, and a bitter taste in the mouth. In studies with more than 4000 patients, the incidence of side effects ranged from 3.9 to 4.7 percent, with most appearing by the second day of therapy.

Objective. Plasmid-mediated quinolone resistance (PMQR) plays an important role in the development of clinical resistance to quinolone. The aim of this study was to investigate PMQR determinants among extended-spectrumβ-lactamases- (ESBL-) producingKlebsiella pneumoniaerecovered from patients with nosocomial urinary tract infection (UTI).Methods. A total of 247 ESBL-producingK. pneumoniaeisolates were collected from 750 patients with UTI. ESBL production was confirmed by double disc synergy test and combined disc diffusion test. The prevalence of PMQR determinants among ESBL-producingK. pneumoniaewas assessed using PCR method.Results. The rates of resistance to antimicrobial agents in present study varied from 14.2% to 98.8%. In comparison with other PMQR genotypes, the frequency ofaac(6′)-Ib(68.8%) was strikingly high. Of the 247 isolates tested,qnrA, qnrB, qnrS,andqepAgenes were present in 3.6%, 1.6%, 1.2, and 2%, respectively.oqxAandoqxBwere detected in 56.7% and 54.6% of isolates. The predominant coexisting ESBL and PMQR profile among our isolates includedblaCTX-Mandaac(6′)-Ib, oqxA, oqxB(28.3%) andblaTEM,blaSHVandaac(6′)-Ib, oqxA,andoqxB(19.4%) profile.  Conclusion. Given the linkage observed between resistance to quinolones and beta lactam antibiotics, therapeutic protocol with fluoroquinolones and beta lactam antibiotics should be seriously revised in Tehran hospitals.
