Bacteria associated with hospital infections are found in raw meat

(Barcelona Institute for Global Health (ISGlobal)) Bacteria of the Acinetobacter ACB complex, which are frequently acquired in hospital settings, can also be found in beef meat, according to a study led by ISGlobal, an institution supported by ‘la Caixa’ and performed with meat samples from markets in Lima, Peru. Although the isolates were susceptible to most antibiotics, these results suggest that raw meat can act as a reservoir for these pathogenic bacteria.

In this research, alginate was used as supporting material of immobilized beads to maintain high degradation efficiency. Applying CaCl2 freeze drying and acidic solutions led to the reusability of the beads. Ca-alginate beads can be reused for more than 21 cycles of repeated CaCl2 freeze drying and 16 cycles of t…

Tigecycline is a reserve antibiotic increasingly used for the treatment of multidrug-resistant bacteria, especially Klebsiella pneumoniae and Acinetobacter baumannii. At present, there are concerns regarding the testing and interpretation of tigecycline susceptibility to bugs such as K. pneumoniae and A. baumannii, which limit clinicians in appropriate usage. Use of appropriate method for testing such as broth microdilution is essential. In addition, tigecycline susceptibility testing is a c…

Empiric antibiotic therapy with a betalactam is standard of care in febrile neutropenia (FN), and is given to prevent early death. The addition of vancomycin is recommended in certain circumstances but the quality of evidence is low, reflecting the lack of clinical data. In order to characterize the epidemiology of early death and shock in FN, we reviewed all episodes of FN from 2003 to 2017 at University Hospital, Federal University of Rio de Janeiro, and looked at factors associated with shock at first fever and early death (within 3 days from first fever) by univariate and multivariate analyses. …

We evaluated the toxicity of surfactants against different predatory bacteria. Tests with Bdellovibrio bacteriovorus HD100 and SDS, an anionic surfactant, showed the predator was very sensitive; 0.02% SDS completely killed the predatory population (7-log loss;

A common strategy to prevent HAI is bathing patients with chlorhexidine gluconate (CHG). However, the effectiveness of CHG bathing against multidrug-resistant Acinetobacter baumannii (MDRAB) is still controversial.AimTo perform a syste…

The goal of this study was to isolate, screen, and characterize Arctic microbial isolates from Expedition Fjord, Axel Heiberg Island, Nunavut, Canada capable of inhibiting the growth of foodborne and clinically relevant pathogens. Arctic bacteria were isolated from twelve different high Arctic habitats pertaining to active layer permafrost soil, saline spring sediments, lake sediments, and endoliths. This was achieved using (1) the cryo-iPlate, an innovative in situ cultivation device within active layer permafrost soil and (2) bulk plating of Arctic samples by undergraduate students that applied standard culturing. To mit…

CONCLUSIONS: The photolytic curcumin treatment could be a potential alternative to antibiotics for bacterial infection. In this study, the shotgun proteomic strategy allows us to explore the possible bactericidal mechanisms under this oxidative stress. The result provides a reference for future studies on the enhancement of the action of photolytic curcumin.

Novel alginate hydrogels with silver nanoparticles (AgNPs) and honey components were produced with the aim to target multidrug-resistant bacterial strains causing nosocomial wound infections. AgNP synthesis was optimized in highly concentrated honey solutions so that a 5-month stable, colloid solution with 50% of honey and ~ 8 nm AgNPs at neutral pH was obtained. The colloid solution was further used to produce nano-composite Ag/alginate hydrogels in different forms (microbeads, microfibers and discs) that retained all AgNPs and high fractions of honey components (40-60%) as determined by the phenol-sulfu…

However, the effects of UV treatment on microbial control and disinfection by-products (DBPs) formation in real municipal drinking water systems are poorly understood. Here, we collected water samples from three real drinking water systems in Beijing and Tianjin to…
