Abstract:

Cherry tomatoes, a very popular fruit, are highly susceptible to microbial infestation, which cause significant economic losses. In order to preserve cherry tomatoes better, we treat them with a Chitosan (CTS) and Curdlan (CUR) composite coating. The lowest inhibitory concentration of CTS/CUR composite coating on Serratia marcescens and Pseudomonas syringae, the growth curves, and the changes of the cell lysis rate were determined to explore the inhibitory mechanism of CTS/CUR composite coating on Serratia marcescens and Pseudomonas syringae and the microscopic morphology of Serratia marcescen

Serratia marcescens is a ubiquitous, facultatively anaerobic, gram-negative bacillus that has been cited to cause infection in immunocompromised populations. In the literature, S marcescens infections of the lower extremity have presented as granulomatous ulceration, abscess, bullous cellulitis, and necrotizing fasciitis. Herein we present a series of three cases of lower-extremity infections in which S marcescens was the sole or a contributing pathogen. We discuss the commonalities of these three cases as well as with those previously cited. All three patients presented with some combination

At our institution we have noted emergence of CR strains in clinical isolates including a growing number of Serratia marcescens. CR in Serratia marcescens in the United States is mostly reported to be encoded by the SME family of chromosomally encoded carbapenemases, while in Asia it has been described being mediated by transmissible plasmids such as KPC.

Serratia marcescens is an important pathogen with noteworthy hydrophobicity characteristics as assessed by microbial adhesion to hydrocarbons.

Also, little attention has been paid hitherto to the structural features and chemical composition of the cell surface.

One such pest is the rice stem borer (Scirpophaga innotata), which infests rice stems and poses a significant threat. To combat these pests, various microbial agents have been developed for effective pest control. Among these, the endophytic microbe in biological plant protection plays a key role in the program of sustainable pest management.

Abstract:

Diseases that occur in silkworms include soft rot, hardening disease, digestive diseases, and sepsis. However, research on the causes of bacterial diseases occurring in silkworms and the resulting changes in the microbial community is lacking. Therefore, we examined the morphological characteristics of sepsis and changes in the microbial community between silkworms that exhibit a unique odor and healthy silkworms; thus, we established a relationship between disease-causing microorganisms and sepsis. After producing a 16S rRNA amplicon library for samples showing sepsis, we obtained information

Abstract:

Research on new fibrinolytic agents has been oriented towards the discovery of microbial proteases with plasmin-like activity, as alternative thrombolytic agents for thrombosis treatment. This study reports the characterization of an extracellular serine metalloprotease of approximately 56 kDa, with fibrinolytic and fibrinogenolytic activity, isolated from a S. marcescens strain obtained from the Amazon (CBAM 519). The enzyme showed optimum activity at pH 9 and temperature of 37 °C. Activity was reduced in the presence of Na+, Cu2+ and Fe2+ ions, and increased with Mn2⁺. The enzyme did not sho

Background. It has been known that there are microecology disorders during lung cancer development. Theoretically, intratumoral microbiota (ITM) can impact the lung cancer (LC) survival and treatment efficacy. This study conducted a follow-up investigation of non-small cell lung cancer (NSCLC) patients without lung infection to prove whether ITM indeed impacts the first-line treatment efficacy and survival. Methods. We enrolled all patients diagnosed with NSCLC in our department from 2017 to 2019, whose tumor samples were available (through surgery or biopsy) and sent for pathogen-targeted seq

Gram-negative rods (GNR) carrying the transferable carbapenem resistance gene blaIMP, includingPseudomonas aeruginosa and Serratia marcescens, have been isolated from more than 20 hospitals in Japan.

To address this, a system for the rapid detection of theblaIMP gene with a simple DNA preparation and by enzymatic detection of PCR products was develope

Biosafety laboratory is an important place to study high-risk microbes. In biosafety laboratories, with the outbreak of infectious diseases such as COVID-19, experimental activities have become increasingly frequent, and the risk of exposure to bioaerosols has increased. To explore the exposure risk of biosafety laboratories, the intensity and emission characteristics of laboratory risk factors were investigated. In this study, high-risk microbe samples were substituted with Serratia marcescens as the model bacteria. The resulting concentration and particle size segregation of the bioaerosol p

Oligopeptidase B (OPB), a serine protease with trypsin-like specificity that processes low-molecular-weight peptides and oligopeptides, is present in bacteria and certain parasites but absent in mammals. This unique distribution makes OPB an attractive and selective target for antimicrobial drug development. Methods: Three-dimensional models of OPB
