Infections by Cronobacter spp. are hazardous to infants since they can lead to neonatal meningitis, bacteremia, and necrotizing enterocolitis. Cronobacter spp. are frequently resistant to β-lactam derivatives, macrolides, and aminoglycosides. In addition, multi-resistant strains have also been detected. In China, the isolation rate of Cronobacter spp. from commercial powdered infant formula (PIF) or follow-up formula (FUF) is relatively high. Nevertheless, clinical cases of Cronobacter infection have been ignored to date...

CONTEXT: Potentially inappropriate prescriptions (PIPs) of antibiotics (antibiotic-PIPs) are generally detected by applying implicit definitions based on expert opinion. Explicit definitions are less frequently used, even though this approach would enable the automated detection of antibiotic-PIPs in electronic health records. Here, we systematically reviewed explicit definitions of antibiotic-PIPs used in studies of older adults. METHOD: We searched the MEDLINE(®), Scopus(®) and Web of Science(TM) core collection databases with a combination of three terms and their synonyms: "potentially inappropriate prescription" AND "antibiotic treatment" AND "older patients"...

BACKGROUND: Perioperative antibiotic prophylaxis against gram positive and gram negative infections is considered standard of care in the perioperative management of patients undergoing cranial surgery. The antibiotic regimen which best reduces the risk of surgical site infections (SSIs) remains controversial. OBJECTIVES: A systematic literature review and meta-analysis were conducted to examine the effect of various prophylactic antibiotics on infection incidence among patients undergoing cranial surgeries...

INTRODUCTION: Typhoid fever is an endemic disease in India against which many antibiotics are available. In the recent times, emerging resistance to traditional antibiotics, such as Ampicillin, Chloramphenicol and Trimethoprim/sulfamethoxazole, Azithro-mycin and third generation Cephalosporins are being reported and increasingly being used in the treatment of invasive Salmonella infections. However, the latter two drugs have been reported with occasional clinical failures. Currently, we do not have data regarding their drug resistance levels in the recent isolates of Salmonella enterica subspecies enterica serotype Typhi...

In this study, three novel, sensitive, simple and validated spectrophotometric and spectrofluorimetric methods have been proposed for estimation of some important antimicrobial drugs. The first two methods have been proposed for estimation of two important third-generation cephalosporin antibiotics namely, cefixime and cefdinir. Both methods were based on condensation of the primary amino group of the studied drugs with acetyl acetone and formaldehyde in acidic medium. The resulting products were measured by spectrophotometric (Method I) and spectrofluorimetric (Method II) tools...

Aminoglycosides are used in treating a wide range of infections caused by Gram-positive and Gram-negative bacteria; however, aminoglycoside resistance is common and occurs by several mechanisms. Among these mechanisms is bacterial rRNA methylation by the 16S rRNA methyl transferase (16S-RMTase) enzymes; but data about the spread of this mechanism in Egypt are scarce. Cephalosporins are the most commonly used antimicrobial agents in Egypt; therefore, this study was conducted to determine the frequency of 16S-RMTase among third generation cephalosporin-resistant clinical isolates in Egypt...

Antimicrobial resistance (AMR) is a major threat to human, animal health, and environment worldwide. For human, transmission occurred through a variety of routes both in health-care settings and community. In animals, AMR was reported in livestock, pets, and wildlife; transmission of AMR can be zoonotic with the probably most important route being foodborne transmission. The Indian Ocean Commission (IOC), composed of Comoros, Madagascar, Mauritius, Reunion (France), and Seychelles recognized the surveillance of AMR in both animal and human as a main public health priority for the region...

OBJECTIVES: To assess hospital differences in empirical antibiotic use, bacterial epidemiology, and antimicrobial susceptibility for common antibiotic regimens among young infants with urinary tract infection (UTI), bacteremia, or bacterial meningitis. METHODS: We reviewed medical records from infants <90 days old presenting to 8 US children's hospitals with UTI, bacteremia, or meningitis. We used the Pediatric Health Information System database to identify cases and empirical antibiotic use and medical record review to determine infection, pathogen, and antimicrobial susceptibility patterns...

BACKGROUND: Central nervous system nocardial infection is a rarely reported disease that usually affects patients with predisposing and debilitating conditions but also the immunocompetent population. The most common variant affecting the brain is Nocardia farcinica. Management of brain nocardiosis is troublesome and requires consideration of the severity of the underlying systemic disease, the difficulties in identifying the bacterium and the frequent delay in initiating adequate therapy...

Neisseria meningitidis is a causative agent of community-acquired sepsis and meningitis in humans. These diseases are associated with high mortality and morbidity if treatment is not started promptly. The empiric antibiotic treatment depends on patient factors and local epidemiology. In the past years, an increased number meningococcal strain with reduced susceptibility to penicillin has also been described. We analysed the susceptibility pattern of 11 N. meningitidis strains isolated between 2013 and 2016...

CTX-M-15 type β-lactamase has the ability to hydrolyse cefotaxime, a third generation cephalosporin. The infections caused by multidrug resistant strains, especially CTX-M-15 producing strains are being treated with carbapenem group of β-lactam antibiotics. The objective of the study was to know if cefotaxime in combination with doripenem (carbapemen antibiotic) at very low concentration, inhibits the CTX-M-15 producing bacterial strains. blaCTX-M-15 gene was cloned to express CTX-M-15 enzyme and construct CTX-M-15 producing strain...

BACKGROUND: The use of antimicrobials in food animals and the emergence of antimicrobial resistance are global concerns. Ceftiofur is the only third-generation cephalosporin labeled for veterinary use in the USA, and it is the drug of choice in the majority of dairy farms for the treatment of mastitis. Here, we use next-generation sequencing to describe longitudinal changes that occur in the milk microbiome before, during, and after infection and treatment with ceftiofur. Twelve animals were intramammary challenged with Escherichia coli in one quarter and randomly allocated to receive intramammary treatment with ceftiofur (5d) or untreated controls...

The clinical benefits of an antimicrobial de-escalation strategy were compared with those of a no-switch strategy in bacteremic patients. Adults with community-onset monomicrobial Escherichia coli, Klebsiella species and Proteus mirabilis bacteremia treated empirically using broad-spectrum beta-lactams, including third-generation cephalosporins (GCs), fourth-GC or carbapenems, were treated definitively with first- or second-GCs (de-escalation group), the same regimens as empirical antibiotics (no-switch group), or antibiotics with a broader-spectrum than empirical antibiotics (escalation group)...

Macrolides represent a large family of protein synthesis inhibitors with high clinical interest due to their applicability for human medicine. Macrolides are composed of a macrocyclic lactone of different ring sizes, to which one or more deoxy-sugar or amino-sugar residues are attached. Macrolides act as antibiotics by binding to bacterial 50S ribosomal subunit and interfering with protein synthesis. The high affinity of macrolides for bacterial ribosomes, together with the highly conserved structure of ribosomes across virtually all of the bacterial species, is consistent with their broad-spectrum activity...

Multidrug resistance is a global threat as the clinically available potent antibiotic drugs are becoming exceedingly scarce. For example, increasing drug resistance among gram-positive bacteria is responsible for approximately one-third of nosocomial infections. As ribosomes are a major target for these drugs, they may serve as suitable objects for novel development of next-generation antibiotics. Three-dimensional structures of ribosomal particles from Staphylococcus aureus obtained by X-ray crystallography have shed light on fine details of drug binding sites and have revealed unique structural motifs specific for this pathogenic strain, which may be used for the design of novel degradable pathogen-specific, and hence, environmentally friendly drugs...
