Almost 5,000 cases of Pillsbury flour bags recalled after testing positive for E. coli

Manufacturers recalled the bags in 10 states on Friday. E. coli tends to fester in moisture. But a recent CDC investigation into E. coli-infected cookie dough found that's not always the case.

Publication date: Available online 20 July 2019Source: PeptidesAuthor(s): Nathalia Rodrigues de Almeida, Jonathan Catazaro, Maddeboina Krishnaiah, Yashpal Singh Chhonker, Daryl J Murry, Robert Powers, Martin Conda SheridanAbstractThe rapid emergence of resistant bacterial strains has made the search for new antibacterial agents an endeavor of paramount importance. Cationic antimicrobial peptides (AMPs) have the ability to kill resistant pathogens while diminishing the development of resistance. Citropin 1.1 (Cit 1.1) is an AMP effective against a broad range of pathogens. 20 analogues of Cit 1.1 were prepared to understand...

ConclusionsWe think that the most appropriate antibiotic to be chosen for the outpatients for empirical treatment in all age groups in our region, is as oral nitrofurantoin and parenteral amikacin. Also the appropriate parenteral antibiotics that should be selected for the empirical treatment of inpatients UTI in all age groups are the TZP, amikacin and carbapenems.

ConclusionsST10 is considered a high-risk clone worldwide. This type of mcr-1-harboring clone is a major concern for human and animal health and must be under close surveillance.In this work we detected the presence of mcr-1 for the first time in our country, albeit in an allodemic manner, associated with different antibiotic resistance genes and from diverse clinical contexts.Considering that colistin is often the last therapeutic option available for multidrug-resistant Gram-Negative Bacilli infections, it is necessary to maximize precautions to avoid the dissemination of isolates carrying mcr-1.

This study was designed to determine the in-vitro antibacterial and ex-vivo immunomodulatory efficacy of garlic (Allium sativum) and ginger (Zingiber officinale) extracts post dietary supplementation for 900-one-day-old Sasso broiler chicks. The in-vivo protective action of these extracts against avian pathogenic MDR Escherichia coli (E. coli) O78 challenge was evaluated after 21 days of extracts supplementation. Garlic extract exhibited broader antimicrobial spectra against MDR E. coli O78 and S. aureus isolates. Through the 21 days of garlic or ginger dietary supplementation, the chicks’ innate immune response was ...

This study aimed to evaluate ETEC detection methods focusing on the major serogroups (O6, O25, O27, O148, O153, O159, and O169) with steps of enrichment, isolation, and real-time PCR targeting genes encoding the heat-labile enterotoxin (LT) and heat-stable enterotoxin (ST). ETEC strains (n = 20) were grown to 7.0–8.9 log CFU/mL in modified E. coli broth (mEC) at 42 °C for 18 h. The strains formed colonies typically representing E. coli on sorbitol MacConkey agar and Shiga toxin-producing E. coli on CHROMagar STEC base agar. The minimum detection levels for real-time PCR assays targeting LT and ST genes we...

In this study, the previously characterized reduction-oxidation sensitive green fluorescent protein (roGFP2) was used to elucidate the redox changes of the genetically engineered Escherichia coli strain, SHuffle. SHuffle cells were demonstrated to be under constitutive oxidative stress and responding transcriptionally in an OxyR-dependent manner. Using roGFP2 fused to either glutathione (GSH)- or hydrogen peroxide (H2O2)- sensitive proteins (glutaredoxin 1 or Orp1), the cytosolic redox state of both wild type and SHuffle cells based on GSH/GSSG and H2O2 pools was measured. These probes open the path to in vivo studies of r...

Publication date: Available online 20 July 2019Source: Journal of Bioscience and BioengineeringAuthor(s): Nisar A. Shakir, Tahira Bibi, Mehwish Aslam, Naeem RashidThe genome sequence of Thermococcus kodakarensis contains an open reading frame, TK0376, annotated as ADP-dependent phosphofructokinase belonging to pfkC family. The encoding gene was expressed in Escherichia coli and the gene product was characterized. The recombinant protein was produced in soluble and active form. Phosphofructokinase activity of TK0376 was metal-ion dependent and the highest activity (5090 μmol min−1 mg−1) was found in...

This study aimed to develop novel multifunctional soy protein-based packaging materials with the incorporation of cellulose nanofibril (CNF), Cedrus deodara pine needle extract (PNE), and lactic acid. The effects of the loaded components on the physical and functional properties of nanocomposites were evaluated. Results indicate that the incorporation of CNF into the composite enhanced its tensile strength due to the filling effects of CNF. The addition of CNF and PNE greatly enhanced the light barrier property of films. Moreover, the films containing PNE displayed strong antioxidant activity and significantly improved ant...

Wei-Zhong Liu Three new γ-hydroxyl butenolides (1–3), a pair of new enantiomeric spiro-butenolides (4a and 4b), a pair of enantiomeric cyclopentenones (5a new and 5b new natural), and six known compounds (6–11), were isolated from Aspergillus sclerotiorum. Their structures were established by spectroscopic data and electronic circular dichroism (ECD) spectra. Two pairs of enantiomers [(+)/(–)-6c and (+)/(–)-6d] obtained from the reaction of 6 with acetyl chloride (AcCl) confirmed that 6 was a mixture of two pairs of enantiomers. In addition, the X-ray data confirmed tha...
