Prevalence and Antimicrobial-Resistant Features of Shigella Species in East Africa from 2015-2022: A Systematic Review and Meta-Analysis
CONCLUSION: The pooled estimate indicates high burden of Shigella infection in East Africa, as well as a high proportion of drug resistance pattern to tetracycline, ampicillin, chloramphenicol, and amoxicillin. Therefore, initiating and scale-up of performing drug susceptibility test for each shigellosis case need to be considered and strengthened.PMID:37692062 | PMC:PMC10492654 | DOI:10.1155/2023/8277976

Investigating the effects of irrigation with indirectly recharged groundwater using recycled water on soil and crops in semi-arid areas
Environ Pollut. 2023 Sep 8:122516. doi: 10.1016/j.envpol.2023.122516. Online ahead of print.ABSTRACTThe utilization of direct wastewater for irrigation poses many environmental problems such as soil quality deterioration due to the accumulation of salts, heavy metals, micro-pollutants, and health risks due to undesirable microorganisms. This hampers its agricultural reuse in arid and semi-arid regions. To address these concerns, the present study introduces a recent approach that involves using indirectly recharged groundwater (GW) with secondary treated municipal wastewater (STW) for irrigation through a Soil Aquifer Trea...

Preparation of polyhydroxyalkanoate-based magnetic microspheres for carbonyl reductase purification and immobilization
Int J Biol Macromol. 2023 Sep 8:126814. doi: 10.1016/j.ijbiomac.2023.126814. Online ahead of print.ABSTRACTA polyhydroxyalkanoate (PHA) magnetic microsphere was designed for one-step purification and immobilization of a novel carbonyl reductase (RLSR5) from recombinant Escherichia coli lysate. The hydrophobic core of this microsphere was composed of a highly biocompatible polymer, poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx), in which magnetic Fe3O4 particles were embedded during solvent evaporation. The hydrophilic shell of the fusion protein formed by PHA particle-binding protein (PhaP) and RLSR5 (PR) was expre...

Investigation of the potential roles of adipose stem cells and substances of natural origin in the healing process of E. coli infected wound model in Rats
Tissue Cell. 2023 Sep 4;85:102214. doi: 10.1016/j.tice.2023.102214. Online ahead of print.ABSTRACTSkin infections by pathogenic microorganisms are a serious problem due to the potential of dissemination through the bloodstream to various organs causing toxic effects that may be up to mortality. Escherichia coli (E. coli) is one of the most predominant Gram-negative bacterial species present globally with great attention for investigation. The current study is designed to investigate the possible role of adipose tissue-derived stem cells (ADSCs), as well as natural products such as Trichoderma viride (T. viride) extract, Sa...

Solar heterogeneous photo-Fenton for complete inactivation of Escherichia coli and Salmonella typhimurium in secondary-treated wastewater effluent
Chemosphere. 2023 Sep 8:140132. doi: 10.1016/j.chemosphere.2023.140132. Online ahead of print.ABSTRACTIn this work, complete elimination of Escherichia coli and Salmonella typhimurium was achieved in 120 min using a heterogeneous photo-Fenton process under sunlight at pH 6.5 in distilled water. A face-centered composite central design 22 with one categoric factor and three replicates at the central point was used to evaluate the effect of iron (III) oxide concentration (0.8-3.4 mg L-1), H2O2 (2-10 mg L-1), and the type of iron oxide phase (maghemite and hematite) on the inactivation of both bacteria. The results showed tha...
