Modulation of posterior intestinal mucosal proteome in rainbow trout ( Oncorhynchus mykiss ) after Yersinia ruckeri infection

This study showed thatY. ruckeri infection can alter protein abundance involved in serine-type carboxypeptidase, cysteine and aspartic-type endopeptidases, metallopeptidases, antioxidant defense, calcium ion binding, glycolytic and carbohydrate metabolic processes in the proteome of the intestinal mucosa of rainbow trout.

This study is aimed at offering an overview of the prevalence of Yersinia enterocolitica and related species in San Luis, Argentina, from samples of diverse origin received in our laboratory between 1984 and 2014, and providing an analysis of the distribution of Yersinia isolates according to their isolation sources, highlighting bioserotypes and potential reservoirs and vehicles of transmission to humans. From a total of 4572 samples of human, animal, food and environmental origins analyzed by traditional culture methods and molecular techniques, 229 (5%) samples were Yersinia positive. The highest frequency of Yersinia i...

Authors: Miletic S, Goessweiner-Mohr N, Marlovits TC Abstract The type III secretion system (T3SS) is an essential virulence factor of many pathogenic bacterial species including Salmonella, Yersinia, Shigella and enteropathogenic Escherichia coli (EPEC). It is an intricate molecular machine that spans the bacterial membranes and injects effector proteins into target host cells, enabling bacterial infection. The T3SS needle complex comprises of proteinaceous rings supporting a needle filament which extends out into the extracellular environment. It serves as the central conduit for translocating effector proteins. ...

To better understand the molecular characteristics of multidrug-resistant and hypervirulent K. pneumoniae of animal origin, fifteen K. pneumoniae strains from the liver, blood of sick pigs and chicken feces were collected. All K. pneumoniae isolates were subjected to antimicrobial susceptibility testing, string test...

Authors: Bănicioiu-Covei S, Vreju AF, Ciurea PL Abstract The purpose of the study was to correlate the infectious patterns (urogenital, enteral) with ocular manifestations, such as conjunctivitis or acute anterior uveitis in reactive arthritis (ReA). The transversal, observational study was conducted in the Clinic of Rheumatology, University of Medicine and Pharmacy of Craiova, Romania, during the period 2012-2015, and included 112 patients. They were divided into three groups, as follows: Group I (52 ReA cases), Group II (30 other spondyloarthritis cases), Group III (40 osteoarthritis cases). Ophthalmologic scree...

Publication date: Available online 28 October 2019Source: Biochimica et Biophysica Acta (BBA) - BiomembranesAuthor(s): Ankit Gupta, Radhakrishnan MahalakshmiAbstractDeducing the molecular details of membrane protein folding has lately become an important area of research in biology. Using Ail, an outer membrane protein (OMP) from Yersina pestis as our model, we explore details of β-barrel folding, stability, and unfolding. Ail displays a simple transmembrane β-barrel topology. Here, we find that Ail follows a simple two-state mechanism in its folding and unfolding thermodynamics. Interestingly, Ail displays multi...

Publication date: December 2019Source: Food Packaging and Shelf Life, Volume 22Author(s): Jiahao Xu, Ru Song, Yubin Dai, Shuyi Yang, Jie Li, Rongbian WeiAbstractEpoxy resin was conjugated with zinc oxide nanoparticles (ZnO NPs) to prepare antibacterial zinc oxide-epoxy resin (ZnO-ER) composite. The property of ZnO-ER was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and SEM-energy dispersive X-ray spectroscopy (SEM-EDS) assays. Results showed the presence of ZnO NPs on the surface and cross-sections of ZnO-ER composite. The average thickness of ZnO-ER was 392.38 μm. The strong antibacte...

AbstractIn acute gastroenteritis (AGE), identification of the infectious agent is important for patient management. Since symptoms do not reliably identify the agent, microbiological diagnostics are important. Conventional methods lack sensitivity and often take days. Multiplex PCR panels offer fast and sensitive alternatives. Our aim was to assess the performance of the new QIAstat Gastrointestinal Panel (GIP) detecting 24 different gastroenteric pathogens from stool in Cary-Blair transport medium (Adenovirus F 40/41, Astrovirus, Norovirus GI/GII, Rotavirus A, Sapovirus,Campylobacter spp.,Clostridium difficile,Plesiomonas...

Abstract BACKGROUND: Whole blood (WB) is held at room temperature for not more than 24 hours before blood component manufacturing. The ability of several culture collection, skin-derived, and transfusion-related bacteria to survive in WB stored at 22 ± 2°C for 24 hours was investigated in this study. STUDY DESIGN AND METHODS: Twenty-one bacteria of the species Staphylococcus epidermidis, Staphylococcus aureus, Staphylococcus capitis, Streptococcus agalactiae, Serratia liquefaciens, Serratia marcescens, Klebsiella pneumoniae, Escherichia coli, and Yersinia enterocolitica ...
