The bacterial contamination of blood and its components was studied in 517 corpses during the first 2-4 hours after sudden death. Investigations were made with the use of anaerobic cultivation techniques, modern identification methods by means of test systems and gas-liquid chromatography. As revealed in this study, in 14.1% of the corpses different bacteria, belonging to the representatives of normal human microflora, were detected in the blood. More than a half of the isolates were represented by Propionibacterium (P. acnes and P. granulosum). The endogenous way of contamination from the lymph of the hepatic duct seems to be most probable.

A dynamic mass balance model was developed to simulate contamination dynamics in the process water of fresh and frozen fruits, vegetables and herbs (ffFVH) during processing and handling operations. The mass balance relates to the flux of water and product in a wash tank and the number of microbial cells released in the water, inactivated by the water disinfectant or transferred from the water back to the product. Critical variables describing microbial dynamics in water are: (i) the chemical oxygen demand (COD), as an indicator of the concentration of organic matter; (ii) free chlorine (FC) and particularly its antimicrobial fraction, hypochlorous acid (HOCl); and (iii) the microbial population levels.

The antimicrobial properties and widespread incorporation of silver nanoparticles (AgNPs) into consumer products have raised concerns about their potential impact on public health and the environment. This study examined citrate-coated and uncoated AgNPs' antimicrobial effects on microbial growth and their potential to induce antimicrobial resistance (AMR) in the natural environment. We isolated Pseudomonas aeruginosa and Salmonella spp.

School of Environment, South China Normal University, University Town, Guangzhou, China. Electronic address:

The extensive use of antibiotics has led to their frequent detection as residues in the environment. However, monitoring of their levels in groundwater and the associated ecological and health risks remains limited, and the impact of river pollution on groundwater is still unclear. This study focused on the highly urbanized Maozhou River and its groundwater.

Hydrophobic organic compounds (HOCs), such as pyrene, pose significant challenges for microbial-based remediation in soil due to limited substrate availability and the sustainability of augmented microbes. Research targets are to investigate the potential of biofilm-forming bacterial cells to enhance pyrene bioavailability and biodegradation in two different hydrocarbon-contaminated soil microcosms, employing microbiological, molecular, and chemical analysis validated through statistical tools. The microcosm augmented with strong biofilm bacterial consortia (A) significantly enhanced pyrene availability by 1-1.

Microbial indicators for water quality in recirculating shower technology.

Recirculating showers save up to 70-80 % of the water and energy use of conventional showers, but water quality in these systems are not studied very well due to the technology's early stages. The aim of this study was to provide an overview of information available on which microorganisms were investigated and at which densities. Based on this platform we further aimed at identifying key microbial indicators and pathogens for monitoring water quality in these systems by integrating data from the top five waterborne outbreaks with findings from studies on (1) microbial investigations in reuse projects involving shower effluents or combined bathroom streams, (2) shower water effluents, and (3) biofilms in conventional showers.
