Fosfomycin is a broad-spectrum bactericidal antibiotic widely used in pig farms for the treatment of a wide variety of bacterial infections. In this study, the elimination of disodium fosfomycin in colostrum/milk of the sow and the impact of this antibiotic on the microbiota and intestinal morpho-physiology of suckling piglets were analyzed. The average amount of fosfomycin eliminated in colostrum (after administration of 15 mg/kg IM) during the first 10 hr postpartum was 0.85 μg/ml, and the mean residual amount ingested by the piglets was 0...

During the past decades resistance to virtually all antimicrobial agents has been observed in bacteria of animal origin. This chapter describes in detail the mechanisms so far encountered for the various classes of antimicrobial agents. The main mechanisms include enzymatic inactivation by either disintegration or chemical modification of antimicrobial agents, reduced intracellular accumulation by either decreased influx or increased efflux of antimicrobial agents, and modifications at the cellular target sites (i...

Acute pyelonephritis might be complicated by the formation of renal and perirenal abscesses and very rarely by renal vein thrombosis, which is a life-threatening condition. The main causative agents of acute pyelonephritis are enterobacteriaceae with the incidence of extended-spectrum beta-lactamase (ESBL)-producing strains increasing worldwide. We present the case of a 71-year-old Greek man with history of diabetes mellitus and recent hospitalization, who suffered from severe pyelonephritis with renal abscesses formation and associated bacteraemia caused by ESBL-producing Escherichia coli, complicated by extensive thrombosis of the ipsilateral renal vein and its branches, protruding also in the inferior venal cava...

The goal of this study was to examine antimicrobial resistance and characterize the implicated genes in 222 isolates of Escherichia coli from 187 samples of raw milk and the two most popular cheeses in Egypt. E. coli isolates were tested for susceptibility to 12 antimicrobials by a disk diffusion method. Among the 222 E. coli isolates, 66 (29.7%) were resistant to one or more antimicrobials, and half of these resistant isolates showed a multidrug resistance phenotype (resistance to at least three different drug classes)...

PURPOSE: Prolonged and profound neutropenia is common among hematology and hematopoietic stem cell transplant (HSCT) patients as a result of chemotherapy. The National Comprehensive Cancer Network (NCCN) and Infectious Diseases Society of America (IDSA) currently recommend antibacterial prophylaxis in patients who are deemed at intermediate or high risk for infection. Specifically, fluoroquinolone prophylaxis should be considered for high-risk neutropenic patients. However, with prolonged and frequent exposure to fluoroquinolones, these high-risk patients may develop resistance to these agents...

Introduction: Antibiotic treatment of Urinary Tract Infections (UTI) is becoming increasingly difficult due to emergence of multi-drug resistant (ESBLs, AmpC, CRE) uropathogens. Fosfomycin is an old antibiotic that has evoked renewed interest with unique properties of not sharing any structural similarity and lack of cross-resistance with other antimicrobial agents. Our aim is to evaluate in-vitro activity of Fosfomycin against urinary tract Enterobacteriaceae. Material & Methods: The study period was March 2014 to September 2015...

Urinary tract infections (UTI) are the most common outpatient infections, but predicting the probability of UTI through symptoms and test results can be complex. The most diagnostic symptoms of UTI include change in frequency, dysuria, urgency, and presence or absence of vaginal discharge, but UTIs may present differently in older women. Dipstick urinalysis is popular for its availability and usefulness, but results must be interpreted in context of the patient's pretest probability based on symptoms and characteristics...

The objective of this study was to analyse the distribution and antimicrobial resistance of bacterial uropathogens isolated from outpatients at Henan Provincial People's Hospital. A total of 1419 samples from 823 newly diagnosed and 596 recurrent UTI outpatients culture positive. Escherichia coli was the most common uropathogen. Compared with the recurrent group, the newly diagnosed group had a higher isolation rate of E. coli and Enterobacter cloacae but a lower isolation rate of Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter spp...

PURPOSE: Meropenem/vaborbactam is a novel intravenous antibiotic combining the carbapenem, meropenem, with a novel β-lactamase inhibitor, vaborbactam. Meropenem/vaborbactam is administered as a 3-hour infusion given every 8 hours, thereby potentially restricting an intravenous line for 9 h/d. Intravenous medications may be given concurrently via Y-site when compatibility data are available. Herein, physical compatibility was determined for the identification which medications can be coadministered with meropenem/vaborbactam via Y-site...

PURPOSE: To compare efficacy, safety, and cost-effectiveness of fosfomycin tromethamine with other standard-of-care antibiotics in patients undergoing ureteroscopic lithotripsy. METHODS: This study was a prospective, multicenter, randomized, controlled trial. Eligible patients scheduled for ureteroscopic lithotripsy were randomly assigned to receive either fosfomycin (fosfomycin group, N = 101 patients) or standard-of-care antibiotic therapy as prophylaxis (control group, N = 115 patients)...

PURPOSE: To systematically review and meta-analyse available evidence comparing fosfomycin trometamol (FT) to fluoroquinolone (FQ) prophylaxis to prevent transrectal ultrasound-guided prostate biopsy (TRUSPB) related infectious complications. METHODS: Electronic databases were queried for studies comparing FT to FQ-based TRUSPB prophylaxis. Studies were assessed for comparable outcomes and methodological quality (ROBINS-I modification). The primary outcome measure was the relative odds of overall infectious complications following TRUSPB according to FT/FQ treatment, which was evaluated with meta-analysis...

We investigated the prevalence and characteristics of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolates from Japanese pigs. A total of 345 pig fecal specimens were collected from 30 farms in Aichi prefecture, Japan, between June 2015 and April 2016, and 22 unique ESBL-producing E. coli were isolated from 16 samples of eight farms. The ESBL types included CTX-M-15 (54.5%), CTX-M-55 (27.2%), CTX-M-3 (0.9%), and CTX-M-14 (0.9%). The predominant plasmid replicon type was IncN, and they carried blaCTX-M-55...

BACKGROUND: Transrectal ultrasound-guided prostate biopsy (TRUS-Bx) is typically considered a safe procedure. However, infectious complications have been increasing. OBJECTIVE: To determine the contemporary rate of biopsy-related infectious and noninfectious complications after TRUS-Bx, and identify potential risk factors associated with the complications.

In the present study, we screened a collection of 77 Proteus mirabilis clinical isolates for the presence of mutators, using the frequency of both rifampicin and fosfomycin resistance mutants as markers of spontaneous mutagenesis. We found that none of the strains in our collection are mutators for the rifampicin resistance (RifR) marker. Nevertheless, a significant fraction of the isolates (17%) show high frequencies of fosfomycin resistant mutants (FosR). We show that this increased mutability to FosR correlates with a low level of resistance to Fosfomycin (MICs 8-64μg/ml)...

BACKGROUND: Resistant and virulent Staphylococcus aureus is a global public health challenge. Staphylococcal Bi-component leukotoxins are cytolytic to immune cells and evolve to disarm the innate immunity during infections, hence the severity of the disease.

The emergence of colistin-resistant Klebsiella pneumoniae (CoRKp) is a public health concern since this antibiotic has become the last line of treatment for infections caused by multidrug-resistant (MDR) gram-negatives. In this study, we have investigated the molecular basis of colistin-resistance in 13 MDR Kp isolated from 12 patients in a teaching hospital in Sousse, Tunisia. Whole-genome sequencing (WGS) was used to decipher the molecular mechanism of colistin-resistance and to identify the resistome of these CoRKp It revealed a genome of ca...
