Emily J Weston, Teodora Wi, John Papp
Monitoring trends in antimicrobial drug-resistant Neisseria gonorrhoeae is a critical public health and global health security activity because the number of antimicrobial drugs available to treat gonorrhea effectively is rapidly diminishing. Current global surveillance methods for antimicrobial drug-resistant N. gonorrhoeae have many limitations, especially in countries with the greatest burden of disease. The Enhanced Gonococcal Antimicrobial Surveillance Program is a collaboration between the World Health Organization and the Centers for Disease Control and Prevention...

Introduction: Extended-spectrum β-lactamases (ESBLs), including the AmpC type, are important mechanisms of resistance among Klebsiella pneumoniae and Escherichia coli isolates. Objective: The aim of the study was to investigate the occurrence of AmpC-type β-lactamase producers isolated from two hospitals in Tripoli, Libya. Methods: All clinical isolates (76 K. pneumoniae and 75 E. coli) collected over two years (2013-2014) were evaluated for susceptibility to a panel of antimicrobials and were analyzed phenotypically for the ESBL and AmpC phenotype using E-test and ESBL and AmpC screen disc test...

INTRODUCTION: Hospital-associated methicillin-resistant S. aureus (HA-MRSA) remains a significant cause of morbidity and mortality worldwide. We conducted a study to determine risk factors for HA-MRSA in order to inform control strategies in South Africa. METHODS: We used surveillance data collected from five tertiary hospitals in Gauteng and Western Cape provinces during 2014 for analysis. A case of HA-MRSA was defined as isolation of MRSA from a blood culture 48 hours after admission and/or if the patient was hospitalised in the six months prior to the current culture...

Global Pharma Health Fund (GPHF) Minilab™, a semi-quantitative thin-layer chromatography (TLC)-based commercially available test kit, is widely used in drug quality surveillance globally, but its diagnostic accuracy is unclear. We investigated the diagnostic accuracy of minilab system for antimicrobials, using high-performance liquid chromatography (HPLC) as reference standard. Following the Minilab protocols and the Pharmacopoeia of the People's Republic of China protocols, Minilab-TLC and HPLC were used to test five common antimicrobials (506 batches) for relative concentration of active pharmaceutical ingredients...

Although antibiotics are too often used inappropriately in Cambodia, few data have been published on antimicrobial resistance in this country. Epidemic dissemination and the transfer of resistance genes to other bacterial species put the population at risk. The aim of this study was to evaluate the frequency and characteristics of extended-spectrum beta-lactamase (ESBL) enterobacteriaceae (ESBL-E) isolated in consecutive samples tested at Institut Pasteur du Cambodge (IPC) over a four-year period (2012-2015)...

We identified a ceftriaxone-resistant Neisseria gonorrhoeae isolate in a patient in Canada. This isolate carried the penA-60 allele, which differs substantially from its closest relative, mosaic penA XXVII (80% nucleotide identity). Epidemiologic and genomic data suggest spread from Asia. Antimicrobial susceptibility surveillance helps prevent spread of highly resistant N. gonorrhoeae strains.

E. fischeriana has long been used as a traditional Chinese medicine. Recent studies reported that some compounds of E. fischeriana exhibited antimicrobial and immune enhance activity. Innate immune system is essential for the immune surveillance of inner and outer threats, initial host defense responses and immune modulation. The role of natural drug compounds, including E. fischeriana, in innate immune regulation is largely unknown. Here we demonstrated that E. fischeriana compound Dpo is involved in antiviral signaling...

Miniaturized and cost-efficient methods aiming at high throughput analysis of microbes are of great importance for the surveillance and control of infectious diseases and the related issue of antimicrobial resistance. Here we demonstrate a miniature nanosensor based on a honeycomb-patterned silicon nanowire field effect transistor (FET) capable of detection of bacterial growth and antibiotic response in microbiologically relevant nutrient media. We determine the growth kinetics and metabolic state of Escherichia coli cells in undiluted media via the quantification of changes in the source-drain current caused by varying pH values...

Antibiotic use in food-producing animals has considerable impact on public health, especially with respect to the development and spread of antibiotic resistance. Pigs represent one of the main species in which antibiotics are frequently used for different purposes. Surveillance of antibiotic consumption and dose appropriateness, through novel approaches based on defined daily doses, is strongly needed to assess farms' antibiotic risk, in terms of spread of antibiotic resistance and possibile presence of residues in meat...

The rapid spreading of polymyxin E (colistin) resistance among bacterial strains through the horizontally transmissible mcr-1 and mcr-2 plasmids has become a serious concern. The emergence of these genes in Shiga toxin-producing Escherichia coli (STEC), a group of human pathogenic bacteria was even more worrisome, urging us to investigate the prevalence of mcr genes among STEC isolates. A total of 1000 STEC isolates, recovered from livestock, wildlife, produce and other environmental sources in a major production region for leafy vegetables in California during 2006-2014, were screened by PCR for the presence of plasmid-borne mcr-1 and mcr-2...

Anaerobic bacteria have pivotal roles in the microbiota of humans and they are significant infectious agents involved in many pathological processes, both in immunocompetent and immunocompromised individuals. Their isolation, cultivation and correct identification differs significantly from the workup of aerobic species, although the use of new technologies (e.g., matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, whole genome sequencing) changed anaerobic diagnostics dramatically...

Antimicrobial resistance (AMR) among bacteria isolated from food-producing animals is a growing concern with implications for public health. AMR surveillance is essential to identify resistance trends and help in the design of effective and efficient control strategies. The aim of the study was to describe the antimicrobial susceptibility of pathogenic Escherichia coli isolated from three livestock productions in France (cattle, swine and poultry). The trend in resistance to the most commonly prescribed antibiotics in animal health was analysed as follows: amoxicillin (penicillin), spectinomycin or streptomycin (aminoglycoside), tetracycline and trimethoprim-sulfamethoxazole/Enrofloxacin and ceftiofur were also taken into account as members of critically important antimicrobial families in human and veterinary medicine, that is fluoroquinolones and third-generation cephalosporins, respectively...

Patients may intermittently require antimicrobial therapy with a QTc-prolonging antibiotic, which presents a challenge for prescribers of patients already taking a QTc-prolonging antiarrhythmic. Manufacturers recommend close monitoring for evidence of QTc-prolongation with the concomitant use of QTc-prolonging medications, but the monitoring parameters are not well-defined. Previous studies recommend a surveillance electrocardiogram (EKG) be completed both before and after the initiation of QTc-prolonging medications, but it is unknown to what degree EKGs displaying the QTc-interval are used to alter physician order entry and pharmacist order verification during concomitant therapy...

OBJECTIVES: This sudy aimed to characterize a blaNDM-1-producing Escherichia coli from a companion dog. METHODS: This strain was isolated from a surveillance study of carbapenem-resistant Gram-negative bacteria and the specie was identified by API 20E system and MALDI-TOF MS. MICs of various antimicrobial agents were determined by agar dilution. Multilocus sequence typing (MLST) and various carbapenemase genes including blaNDM, blaIMP, blaVIM, blaSME, blaIMI, blaKPC, blaGES, blaSPM, blaGIM, blaNMC, blaDIM, blaSIM, blaOXA-23, blaOXA-24, blaOXA-48, blaOXA-51 and blaOXA-58 were screened by PCR...

Antimicrobial resistance poses a growing threat to public health and the provision of health care. Its surveillance should provide up-to-date and relevant information to monitor the appropriateness of therapy guidelines, antibiotic formulary, antibiotic stewardship programmes, public health interventions, infection control policies, and antimicrobial development. In Europe, although the European Antimicrobial Resistance Surveillance Network provides annual reports on monitored resistant bacteria, national surveillance efforts are still fragmented and heterogeneous, and have substantial structural problems and issues with laboratory data...

In the last decade there has been a rapid global spread of methicillin-resistant Staphylococcus pseudintermedius (MRSP) clones displaying multidrug resistance in dogs. We investigated prevalence, antimicrobial susceptibility and clonal distribution of MRSP isolated from clinical canine samples between during 2011-2014. Following species identification by nuc PCR, MRSP were confirmed by the presence of mecA and characterized by antimicrobial susceptibility testing, Pulsed Field Gel Electrophoresis (PFGE), SCCmec typing, and Multi-Locus Sequence Typing (MLST) of a few isolates having distinct PFGE profiles...

INTRODUCTION: Members of the Bacteroides fragilis group are the most important components of the normal human gut microbiota, but these bacteria can cause severe infections as well. Due to the frequent usage of antibiotics, the spreading of the MDR strains is a real threat worldwide. MATERIALS AND METHODS: In a multicentre study 400 Bacteroides isolates from five Hungarian microbiological laboratories were cultured and identified by MALDI TOF-MS. The MIC values of ten antibiotics were determined by the agar dilution method and evaluated by the breakpoints of EUCAST or CLSI...
