Acquisition and transfer of antibiotic resistance genes in association with conjugative plasmid or class 1 integrons of Acinetobacter baumannii.

PLoS One 2018 6;13(12):e0208468. Epub 2018 Dec 6.

Department of Microbiology and Parasitology, Faculty of Medical Science, Naresuan University, Phitsanulok, Thailand.

Conjugation is a type of horizontal gene transfer (HGT) that serves as the primary mechanism responsible for accelerating the spread of antibiotic resistance genes in Gram-negative bacteria. The present study aimed to elucidate the mechanisms underlying the conjugation-mediated gene transfer from the extensively drug-resistant Acinetobacter baumannii (XDR-AB) and New Delhi Metallo-beta-lactamase-1-producing Acinetobacter baumannii (NDM-AB) to environmental isolates of Acinetobacter spp. Conjugation experiments demonstrated that resistance to ticarcillin and kanamycin could be transferred from four donors to two sodium azide-resistant A.

Understanding the microbial basis of body odor in pre-pubescent children and teenagers.

Microbiome 2018 Nov 29;6(1):213. Epub 2018 Nov 29.

Computational and Systems Biology, Genome Institute of Singapore, Singapore, 138672, Singapore.

Background: Even though human sweat is odorless, bacterial growth and decomposition of specific odor precursors in it is believed to give rise to body odor in humans. While mechanisms of odor generation have been widely studied in adults, little is known for teenagers and pre-pubescent children who have distinct sweat composition from immature apocrine and sebaceous glands, but are arguably more susceptible to the social and psychological impact of malodor.

BACKGROUND Antimicrobial resistance of nosocomial pathogens has become a worldwide problem that leads to major healthcare and economic burdens. Regional antimicrobial resistance profiles are needed to inform selection of proper antimicrobial agents. MATERIAL AND METHODS In collaboration with the Hospital Infection Control Office at our hospitals, we analyzed the constitution of nosocomial pathogens and the corresponding drug-resistance profiles.

[Analysis of distribution and drug resistance of pathogens from the wounds of 1 310 thermal burn patients].

Zhonghua Shao Shang Za Zhi 2018 Nov;34(11):802-808

State Key Laboratory of Trauma, Burns and Combined Injury, Institute of Burn Research, the First Affiliated Hospital of Army Medical University (the Third Military Medical University), Chongqing 400038, China.

To analyze the distribution and drug resistance of pathogens from the wounds of thermal burn patients, so as to provide reliable basis for the rational use of antibiotics and the effective control over nosocomial infection. Wound samples of 1 310 thermal burn patients admitted into our burn wards from January 2012 to December 2017 were collected and retrospectively analyzed. API bacteria identification panels and automatical bacteria identification equipment were used to identify pathogens. Read More

iTRAQ-Based Differential Proteomic Analysis Reveals the Pathways Associated with Tigecycline Resistance in Acinetobacter baumannii.

Cell Physiol Biochem 2018 Nov 27;51(3):1327-1339. Epub 2018 Nov 27.

Background/aims: Acinetobacter baumannii is an aerobic and Gram-negative bacterial pathogen with high morbidity and mortality. It remains a serious public health problem arising from its multidrug-resistant and extensive antibiotic resistance spectrum.

Methods: In the present study, iTRAQ coupled with 2D LC-MS/MS was used to evaluate the proteome in standard Acinetobacter baumannii standard strains and tigecycline-resistant strains. Read More

A Cross-Cutting Approach to Surveillance and Laboratory Capacity as a Platform to Improve Health Security in Uganda.

Health Secur 2018 ;16(S1):S76-S86

Kiersten Kugeler, PhD, MPH, is an Epidemiologist, Division of Vector-Borne Diseases, Centers for Disease Control and Prevention, Fort Collins, CO.

Global health security depends on effective surveillance for infectious diseases. In Uganda, resources are inadequate to support collection and reporting of data necessary for an effective and responsive surveillance system. We used a cross-cutting approach to improve surveillance and laboratory capacity in Uganda by leveraging an existing pediatric inpatient malaria sentinel surveillance system to collect data on expanded causes of illness, facilitate development of real-time surveillance, and provide data on antimicrobial resistance.

Investigation of a Carbapenemase-producing outbreak using whole genome sequencing versus a standard epidemiologic investigation.

Antimicrob Resist Infect Control 2018 21;7:140. Epub 2018 Nov 21.

5McGill University, Montreal, QC Canada.

Background: The standard epidemiologic investigation of outbreaks typically relies on spatiotemporal data and pulsed-field gel electrophoresis (PFGE), but whole genome sequencing (WGS) is becoming increasingly used. This investigation aimed to characterize a carbapenemase-producing (CPAb) nosocomial outbreak using WGS compared to a standard outbreak investigation.

Methods: The CPAb outbreak occurred in a single center between 2012 and 2014. Read More

Association between antibiotic consumption and the rate of carbapenem-resistant Gram-negative bacteria from China based on 153 tertiary hospitals data in 2014.

Antimicrob Resist Infect Control 2018 19;7:137. Epub 2018 Nov 19.

2State Key Laboratory for Diagnosis and Treatment of Infectious Diseases, the First Affiliated Hospital of Medicine School, Zhejiang University, 79 Qingchun Road, Hangzhou, China.

Background: This study aimed to investigate the relationship between the rate of carbapenem-resistant Gram-negative bacteria and antibiotic consumption intensity in 153 tertiary hospitals from China in 2014.

Methods: A retrospective study using national surveillance data from 2014 was conducted. Data on the annual consumption of each antibiotic, as well as the rate of carbapenem-resistant Gram-negative bacteria, were collected from each participating hospital, and the correlation between antibiotic consumption and carbapenem- resistant rate was analyzed.

SfnR2 Regulates Dimethylsulfide-Related Utilization in PAO1.

J Bacteriol 2018 Nov 26. Epub 2018 Nov 26.

Department of Chemistry, State University of New York, College of Environmental Science and Forestry, Syracuse, New York, USA

Dimethylsulfide (DMS) is a volatile sulfur compound produced mainly from the degradation of dimethylsulfoniopropionate (DMSP) in marine environments. DMS undergoes oxidation to form dimethylsulfoxide (DMSO), dimethylsulfone (DMSO) and methanesulfonate (MSA), all of which occur in terrestrial environments and are accessible for consumption by various microorganisms. The purpose of the current study was to determine how the enhancer-binding proteins SfnR1 and SfnR2 contribute to the utilization of DMS and its derivatives in PAO1. Read More

Colistin Monotherapy Versus Colistin and Rifampin Combination Therapy in Pneumonia Caused by Colistin-resistant Acinetobacter baumannii: A Randomized Controlled Trial.

J Glob Antimicrob Resist 2018 Nov 23. Epub 2018 Nov 23.

Division of Pulmonology, Department of Internal Medicine, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Korea. Electronic address:

Objectives: We aimed to confirm the synergistic effects of colistin and rifampin combination therapy compared to colistin monotherapy in pneumonia caused by colistin-resistant Acinetobacter baumannii (CoRAB). In addition, we aimed to assess the utility of the Epsilometer-test (E-test).

Methods: We enrolled 9 subjects who had pneumonia caused by CoRAB from July 20, 2016 to June 21, 2018. Read More
