The PL treatments attained greater microbial reductions for higher treatment times and lower initial mould loads. The absence of the UV portion of the radiation spectrum was found to significantly reduce the treatment effectiveness.
The purpose of this study was to determine the etiologic range of the invasive infections and the profiles of resistance to antibiotics in the isolated stems from patients hospitalized in the Sf. Apostol Andrei Emergency Hospital Galati; Sf. Cuv. Parascheva Hospital of Infectious Diseases Galati and Sf. Ioan Hospital for Children of Galati. We analysed 4029 blood cultures in the period 01.01.2014-30.12.2016. Among the bacterial stems frequently isolated were: coagulase-negative staphylococci, S. aureus, E. coli and Klebsiella pneumoniae. The level of resistance to antibiotics increased, expressing resistance phenotypes of clinic and epidemiologic importance, among which we notice the increased incidence of the stems MRSA (28.95%) and MRS (56.07%), and the production of ESBL in E. coli (30%) and Klebsiella pneumoniae (47%).
An industrial cleaning line containing combi-cleaner, indented separator and scourer was evaluated in terms of reducing the microbial and deoxynivalenol (DON) content from wheat grains naturally contaminated with Fusarium spp. The presence of an indented separator in the industrial cleaning line allowed reducing the DON contamination by 30-36% when dealing with grains having 17.71 to 33.34 μg DON/kg, due to the Fusarium contaminated grains removal. In addition, scouring and aspiration succeeded to reduce grain DON contents ranging from 4.31 to 5.89 μg/kg, by 52-54%. The moulds content was reduced by 76.9% and the aerobic mesophilic spore forming bacteria by 81% through separation, classification and aspiration. Despite the fact that the number of microorganisms present on wheat grains increased during tempering, their number are reduced during scouring. This operation succeed to remove most of the impurities and adhering contaminants and as consequence the moulds were reduced in proportion of 70% and the aerobic mesophilic sporeforming bacteria was reduced by 62.5%. These results may allow us considering that the cleaning performed in combi-cleaner associated with indented separator and scourer might be successfully used for reducing the mycotoxins contamination levels of cereals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
