Article Synopsis
  • * A genome-based surveillance study in Hesse, Germany, analyzed 589 CRGNB isolates from 61 hospitals using next-generation sequencing to map the spread and types of resistant bacteria over three years (2017-2019).
  • * The research found that plasmids play a crucial role in spreading carbapenem resistance, with significant horizontal gene transfer leading to local outbreaks and impacting the management of implant-associated infections.

The emergence of antimicrobial-resistant and mastitis-associated is of great concern due to the huge economic losses worldwide. Here, we report draft genome sequences of two strains which were isolated from raw milk samples obtained from mastitis-infected cows in Bangladesh. The strains were isolated and identified using conventional microbiological and molecular polymerase chain reaction (PCR) methods.

Article Synopsis
  • Current infection control protocols for KPC2-CPE assume transmission occurs mainly through carriers, and aim to manage this with containment strategies.
  • A study in Germany (2013-2019) found a unique IncN plasmid in various KPC2-CPE strains, carrying antibiotic resistance genes and indicating its role in the spread of resistance.
  • The research highlights the need to focus on how plasmids contribute to the transmission of KPC2-CPE in healthcare settings for better monitoring and prevention efforts.

The emergence of antimicrobial-resistant, livestock-associated Enterococcus faecalis represents a public health concern. Here, we report the isolation, molecular detection of virulence and antimicrobial resistance determinants, in addition to the phylogenetic analyses of 20 Enterococcus species using whole genome sequencing analysis of 15 Enterococcus faecalis strains including six strains of three novel sequence types, three Enterococcus faecium and two Enterococcus durans. All strains were isolated from food chain animals in South Africa.

The envelope stress response (ESR) of Gram-negative enteric bacteria senses fluctuations in nutrient availability and environmental changes to avert damage and promote survival. It has a protective role toward antimicrobials, but direct interactions between ESR components and antibiotic resistance genes have not been demonstrated. Here, we report interactions between a central regulator of ESR , the two-component signal transduction system CpxRA (onjugative ilus epression), and the recently described mobile colistin resistance protein (MCR-1).

Objectives: Antimicrobial-resistant bacteria of the order Enterobacterales are emerging threats to global public and animal health, leading to morbidity and mortality. The emergence of antimicrobial-resistant, livestock-associated pathogens is a great public health concern. The genera Enterobacter and Lelliottia are ubiquitous, facultatively anaerobic, motile, non-spore-forming, rod-shaped Gram-negative bacteria belonging to the Enterobacteriaceae family and include pathogens of public health importance.

Species within the Enterobacter cloacae complex (ECC) include globally important nosocomial pathogens. A three-year study of ECC in Germany identified Enterobacter xiangfangensis as the most common species (65.5%) detected, a result replicated by examining a global pool of 3246 isolates.

Objectives: Assessment of vancomycin-resistant Enterococcus faecium (VREfm) prevalence upon hospital admission and analysis of risk factors for colonization.

Methods: From 2014 to 2018, patients were recruited within 72 hours of admission to seven participating German university hospitals, screened for VREfm and questioned for potential risk factors (prior multidrug-resistant organism detection, current/prior antibiotic consumption, prior hospital, rehabilitation or long-term care facility stay, international travel, animal contact and proton pump inhibitor [PPI]/antacid therapy). Genotype analysis was done using cgMLST typing.

Antimicrobial resistance (AMR) has become one of the serious global health problems, threatening the effective treatment of a growing number of infections. Machine learning and deep learning show great potential in rapid and accurate AMR predictions. However, a large number of samples for the training of these models is essential.

belonging to the enterohemorrhagic (EHEC), Shiga toxin-producing (STEC) and atypical enteropathogenic (aEPEC) pathotypes are significant foodborne zoonotic pathogens posing serious health risks, with healthy cattle as their main reservoir. A representative sampling of Hungarian cattle farms during 2017-2018 yielded a prevalence of 6.5 and 5.

Extended-spectrum beta-lactamase (ESBL)-producing Escherichia (E.) coli have been widely described as the cause of treatment failures in humans around the world. The origin of human infections with these microorganisms is discussed controversially and in most cases hard to identify.

Shiga-toxin-producing Escherichia coli (STEC) strains of the serogroup O157 are foodborne pathogens associated with severe clinical disease. As antibiotics are counter-indicated for treatment of these infections, they represent prime candidates for targeted application of bacteriophages to reduce infection burden. In this study, we characterised lytic bacteriophages representing three phage genera for activity against E.

Article Synopsis
  • Antimicrobial resistance (AMR) is a significant global health threat, necessitating fast and accurate diagnostic methods, but traditional testing methods are often slow and limited to certain bacteria.
  • This study compared various machine learning techniques (like logistic regression, support vector machine, random forest, and convolutional neural network) to predict AMR using genomic data, revealing that random forests and CNNs generally perform better with high predictive accuracy.
