Presence and characterization of bla-positive carbapenemase-producing Klebsiella pneumoniae from outpatients in Thailand.

Background: Presently, community-associated carbapenemase-producing Enterobacterales (CPE) remains largely unknown and require public attention. This study aimed to investigate the presence of CPE from outpatients in Thailand.

Methods: Non-duplicate stool (n = 886) and urine (n = 289) samples were collected from outpatients with diarrhea and urinary tract infection, respectively.

Research Note: Longitudinal fecal shedding patterns and characterization of Salmonella enterica and mcr-positive Escherichia coli in meat-type ducks raised in an open-house system.

This longitudinal study aimed to determine the fecal shedding pattern and characterize Salmonella enterica and mcr-positive Escherichia coli from meat-type ducks raised in an open-house system in Thailand. Fecal samples (n = 1,475) were collected from ducks over a 6-month period. Overall, the detection rate of S.

Risk Factors for Community-Acquired Urinary Tract Infections Caused by Multidrug-Resistant Enterobacterales in Thailand.

The dissemination of multidrug-resistant Enterobacterales (MDRE) in community settings is becoming a great concern. This study aimed to assess the incidence and risk factors associated with community-acquired urinary tract infections (CA-UTIs) caused by MDRE. A prospective case−control study was undertaken among patients with UTIs visiting an outpatient department in Phitsanulok Province, Thailand.

Acquisition of extended-spectrum β-lactamase-producing Escherichia coli and Klebsiella pneumoniae in intensive care units in Thailand.

This study aimed to assess the prevalence and associated risk factors for extended-spectrum β-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae (ESBL-EK) acquisition among patients staying in medical and surgical Intensive Care Units (ICU) in Northern Thailand. Rectal swabs were collected from 206 ICU patients upon admission and discharge. Overall, the ESBL-EK acquisition rate among patients during ICU stay was 29.

Prevalence of and Emergence of -Carrying in (Diptera: Calliphoridae), Northern Thailand.

This study was undertaken to assess the prevalence of extended-spectrum β-lactamase (ESBL)-producing (ESBL-EC) among blow fly () populations in Northern Thailand. Of 600 blow flies collected from rural ( = 400) and urban ( = 200) areas, 334 blow flies carried ESBL-EC (55.7%).

Risk Factors for Extended-Spectrum β-Lactamase-Producing Enterobacteriaceae Carriage in Patients Admitted to Intensive Care Unit in a Tertiary Care Hospital in Thailand.

Extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE) are important causes of serious infections in intensive care unit (ICU). This study aimed to investigate the risk factors for intestinal carriage of ESBL-PE among patients admitted to ICU, subsequent ESBL-PE infections, and outcomes of these patients. This study prospectively collected rectal swabs from 215 ICU patients in Northern Thailand and ESBL-PE were isolated.

Environmental dissemination of mcr-1 positive Enterobacteriaceae by Chrysomya spp. (common blowfly): An increasing public health risk.

Until recently, the role of insects, and particularly flies, in disseminating antimicrobial resistance (AMR) has been poorly studied. In this study, we screened blowflies (Chrysomya spp.) from different areas near the city of Phitsanulok, Northern Thailand, for the presence of AMR genes and in particular, mcr-1, using whole genome sequencing (WGS).

Risk Factors for Gastrointestinal Colonization and Acquisition of Carbapenem-Resistant Gram-Negative Bacteria among Patients in Intensive Care Units in Thailand.

This study was conducted to investigate the prevalence of and risk factors for colonization and acquisition of carbapenem-resistant (CR) Gram-negative bacteria (GNB) among patients admitted to intensive care units (ICUs) in two tertiary care hospitals in northern Thailand. Screening of rectal swab specimens for CR-GNB was performed on patients at ICU admission and discharge. The phenotypes and genotypes of all isolates were determined.

Occurrence of Extended-Spectrum and AmpC-Type β-Lactamase Genes in Escherichia coli Isolated from Water Environments in Northern Thailand.

Sixty-eight cefotaxime-resistant Escherichia coli isolates were recovered from different water environments in Northern Thailand. Isolates were mostly resistant to ceftazidime and aztreonam (>90%). The most common extended-spectrum β-lactamase-encoding gene was bla (75%) followed by bla (13.
