The aim of this case report was to describe a patient with large lung abscess who had well responded to antibiotic therapy combined with bronchoscopy drainage. We reported a 55-year-old man with a lung abscess presented with initial symptom of acute productive cough for two weeks...

Klebsiella aerogenes is an important opportunistic pathogen with the potential to develop resistance against last-line antibiotics, such as carbapenems, limiting the treatment options. Here, we investigated the antibiotic resistance profiles of 10 K. aerogenes strains isolated from patient samples in the intensive-care unit of a Brazilian tertiary hospital using conventional PCR and a comprehensive genomic characterization of a specific K. aerogenes strain (CRK317) carrying both the bla KPC-2 and bla NDM-1 genes simultaneously...

BACKGROUND: Prosthetic joint infections (PJI) of the shoulder are a devastating complication of shoulder arthroplasty and are commonly caused by Staphylococcus and Cutibacterium acnes. Absorbable calcium sulfate beads are sometimes used for delivering antibiotics in PJI. This study evaluates the in vitro effect of different combinations of gentamicin, vancomycin, and ertapenem in beads made from calcium sulfate cement on the growth of C. acnes and coagulase-negative Staphylococcus strains...

The bacterial cell wall, being a vital component for cell viability, is regarded as a promising drug target. The L, D-Transpeptidase YcbB enzyme has been implicated for a significant role in cell wall polymers cross linking during typhoid toxin release, β-lactam resistance and outer membrane defect rescue. These observations have been recorded in different bacterial pathogens such as Salmonella Typhimurium , Citrobacter rodentium , and Salmonella typhi . In this work, we have shown structure based virtual screening of diverse natural and synthetic drug libraries against the enzyme and revealed three compounds as LAS_32135590, LAS_34036730 and LAS-51380924...

This study extensively analyzed campylobacteriosis surveillance in Portugal from 2009 to 2021, aiming to investigate demographic shifts, seasonal variations, and antimicrobial resistance (AMR) within Campylobacter isolates. Surveillance network and sentinel laboratory-based system data revealed a substantial under-notification of campylobacteriosis cases, suggesting an underestimated disease burden. Notification rates exhibited a paradigm shift, with a notable prevalence among the pediatric population, particularly in children aged 1-4 years, diverging from European reports...

Among carbapenem-resistant Enterobacterales (CRE) are diverse mechanisms, including those that are resistant to meropenem but susceptible to ertapenem, adding further complexity to the clinical landscape. This study investigates the emergence of ertapenem-resistant, meropenem-susceptible (ErMs) Escherichia coli and Klebsiella pneumoniae CRE across five hospitals in San Antonio, Texas, USA, from 2012 to 2018. The majority of the CRE isolates were non-carbapenemase producers (NCP; 54%; 41/76); 56% of all NCP isolates had an ErMs phenotype...

INTRODUCTION: Gram-negative bacteria (GNB) account for about 70% of infections in the intensive care unit (ICU) setting and are associated with significant morbidity and mortality. In recent years, pan-drug resistant (PDR) strains, strains that are not susceptible to any antibiotic, have been emerged and new treatment strategies are required. RESULTS: Fifty eligible patients were recruited in the three groups. A statistically significant reduction in the Sequential Organ Failure Assessment (SOFA) score was observed in the control group on day 4 in comparison to day 0 of VAP ( p = 0...

Ertapenem is a carbapenem antibiotic that is typically prescribed in cases of moderate-to-severe infections, especially ones involving abscess formation. We describe the case of an 82-year-old gentleman who presented with osteomyelitis and abscess formation who developed delirium after 15 days of ertapenem treatment. The patient experienced delusions, insomnia, agitation, and disorientation. The patient's mental status improved and returned to his baseline within 48 hours of halting ertapenem treatment. A high index of suspicion is required to identify and treat ertapenem-induced delirium...

Carbapenem resistant Enterobacteriaceae (CRE) are major human pathogens because, these cause high number of difficult-to-treat infections. Allogeneic hematopoietic stem cell transplant (AHSCT) recipients are highly exposed to these type of bacteria. The aim of our study was to investigate prevalence of CRE colonization in AHSCT patients and to determine genes encoding carbapenem resistance. A retrospective study conducted between January 2015 and December 2019, involved 55 patients colonized with CRE strains...

In recent years water demand drastically increased which is particularly evident in tourism-burdened mountain regions. In these areas, climate neutral circular economy strategies to minimize human impact on the environment can be successfully applied. Among these strategies, treated wastewater reuse and retaining water in storage reservoirs deserve particular attention. This study aimed to determine if recycled water produced with two circular economy systems, namely membrane bioreactor treatment plant (MBR) with UV-light effluent disinfection and a storage reservoir, is safe enough for further use in green areas irrigation in summer and artificial snow production in winter...

UNLABELLED: Ertapenem, a carbapenem-type beta-lactam antibiotic, demonstrates broad-spectrum efficacy against a wide range of Gram-positive and Gram-negative bacteria, including aerobes and anaerobes. Importantly, it demonstrates resistance to virtually all beta-lactamases, including the extended spectrum beta-lactamases (ESBLs). Haematologic complications such as thrombocytosis, haemolysis, anaemia, and neutropenia are infrequent side effects associated with this drug. In this report, we present a rare case of ertapenem-induced thrombocytosis in a 62-year-old female patient who was admitted for a complicated urinary tract infection caused by Escherichia coli ...

The treatment of infections caused by carbapenem-resistant organisms is challenging. Carbapenems in combination with vaborbactam and relebactam are recommended to treat infections caused by extensively drug-resistant organisms including carbapenemase-producing isolates, while ceftazidime-avibactam plus aztreonam, or cefiderocol is recommended for infections caused by New Delhi metallo beta-lactamase (NDM)-producing Enterobacteriaceae . As, in India, except for ceftazidime-avibactam and aztreonam, the other drugs are not approved for marketing, in this case report, the role of a double carbapenem regimen (ertapenem plus meropenem) in the treatment of carbapenem-resistant Klebsiella pneumoniae infections has been presented...
