Chelates, used to increase the uptake of heavy metals in phytoremediation, can also increase the mobility of metals. If plants fail to uptake or stabilize all the mobilized metals, then subsurface soil or groundwater can be contaminated. Therefore, the type and concentration of chelate used and proper site management are important for chelate-aided phytoremediation. In this study, we evaluated...

In Brazil, safe drinking water is not widely available, and consequently waterborne diseases are still associated with high morbidity and mortality rates. Among waterborne bacteria, diarrheagenic Escherichia coli (DEC) should be highlighted. This study targeted the evaluation of enteropathogenic (EPEC), enterotoxigenic (ETEC), and shiga toxin-producing (STEC)/enterohemorrhagic Escherichia coli in...

Vertebral osteomyelitis, also known as spondylolisthesis and ‘kinky back’ is a disease of commercial broiler chickens and broiler breeders with a worldwide distribution, commonly caused by an infection with Enterococcus spp. or Escherichia coli. A typical symmetrical hindlimb paralysis occurs by compression of the spinal cord due to abscessation of the free thoracic vertebra.

Infectious abortions were diagnosed in 56.25% of cases, of which more than half were caused by Listeria spp. in Latvia (Piginka-Vjaceslavova and Ansonska, 2017). Listeria innocua is a common, non-pathogenic bacterial species; however, a haemolytic L. innocua strain has been detected (Johnson et al., 2004; Moreno et al., 2012). Favaro et al. (2014) reported the first case of L. innocua meningitis...

Vinasse is a waste from the alcohol industry that can support microalgal growth because of its mineral and organic contents. Growing microalgae on waste can be a means of its remediation and decrease culture costs. The physiological knowledge of microalgae on waste can generate subsidies to increase biomass productivity. However, few studies have explored the photosynthetic metabolism of...

Abstract Ampicillin is a widely used β-lactam antibiotic that has been detected in various effluents and can alter biological processes used in wastewater treatment such as nitrification. Physiological and kinetic behaviour of a nitrifying consortium in the presence of ampicillin (AMP) (10, 25, and 50 mg/L) was evaluated in batch cultures. Under the experimental conditions (320 ± 8 mg bacterial...

Staphylococcus aureus strains resistant to the last line antibiotic, vancomycin, have been of clinical concern. These include heterogeneous vancomycin-intermediate S. aureus (hVISA) and VISA. The hVISA phenotype cannot be detected by routine laboratory methods. Characterization of hVISA/VISA by new technologies is necessary to differentiate them rapidly from the vancomycin-susceptible isolates (...

Heavy metal pollution in river sediments is one of the most serious problems in the aquatic environment. In this study, thirty-two surface sediment and overlying water samples were collected to evaluate the nutrient levels and heavy metal contents (Mo, Cu, Zn, Ni, Cd, Pb, and Cr) in the Hai River and its tributaries, which is the largest river flowing into Bohai Bay. The enrichment degree and...

Nuclear production and industrial activities led to widespread contamination of the Department of Energy (DOE) managed Savannah River Site (SRS), located in South Carolina, United States. The H-02 wetland system was constructed in 2007 for the treatment of industrial and storm water runoff from the SRS Tritium Facility. Albeit at low levels, mercury (Hg) has been detected in the soils of the H-02...

Halobacterium salinarum R1 is an extremely halophilic archaeon capable of adhesion and forming biofilms, allowing it to adjust to a range of growth conditions. We have recently shown that living in biofilms facilitates its survival under Cu2+ and Ni2+ stress, with specific rearrangements of the biofilm architecture observed following exposition. In this study, quantitative analyses were performed...

Biofilms provide bacteria with protection from environmental stresses and host immune defenses. The pathogenic marine bacterium Vibrio vulnificus forms biofilms and colonizes environmental niches such as oysters. The cabABC operon encodes an extracellular matrix protein CabA and the corresponding type I secretion system, which are essential for biofilm and rugose colony development of V....

As the most carcinogenic, toxic, and economically costly mycotoxins, aflatoxin B1 (AFB1) is primarily biosynthesized by Aspergillus flavus and Aspergillus parasiticus. Aflatoxin biosynthesis is related to oxidative stress and functions as a second line of defense from excessive reactive oxygen species. Here, we find that ethanol can inhibit fungal growth and AFB1 production by A. flavus in a dose...

Pig manure may contain antibiotic residues, antibiotic-resistant bacteria or pathogens, which may reach the environment upon fertilization. During this study, 69 antibiotic residues belonging to 12 classes were quantified in 89 pig slurry samples. These samples were also studied for the presence of Salmonella and for E. coli resistant to meropenem, colistin, ciprofloxacin, or cefotaxim. The...
