Download or read book Current Topics in Salmonella and Salmonellosis written by Mihai Mares and published by BoD – Books on Demand. This book was released on 2017-04-05 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Salmonella comprises an important number of bacterial species able to colonize and infect numerous animal species and humans. Although more than a hundred years passed since its discovery, Salmonella still represents a redoubtable and successful microorganism, difficult to deal with. Whether we discuss about typhoid fever or food poisoning, the public health and financial consequences are practically incalculable. The costs attributable to Salmonella contamination of meat, eggs, and vegetables are also very high worldwide. Antimicrobial resistance in Salmonella isolates is an emerging threat not only in humans, and special measures should be addressed to this global problem. The book Current Topics in Salmonella and Salmonellosis contains a series of reviews about all-important issues concerning these subjects. It comprises 14 chapters grouped in 4 sections emphasizing new insights into pathogenesis, bacterial detection and antibiotic resistance, infections in animals, risk factors, and control strategies. The new genomic data and the exhaustive presentation of molecular pathogenesis bring novelty to the book and can help to improve our knowledge about Salmonella-induced diseases.

Download or read book Biology of Salmonella written by Filipe Cabello and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmonella infections of man and animals continue to be a distressing health problem worldwide. Far from disappearing, the incidence of typhoid fever in developing countries may be far higher than we had imagined. Salmonella food poisoning has increased to one of the major causes of gastroenteritis in the developed world, in itself also an indication that animal salmonellosis is still a major cause for concern. The situation requires a concerted multidisciplinary research effort in order to generate the new information and technology needed to assist in the control of these diseases. This concept was the driving force behind the NATO Advanced Research Workshop on "Biology of Salmonella" held at Portorosa, Messina, Italy, May 11-15, 1992. With additional support from the University of Messina, Medeva Group Research (UK) and the Swiss Serum and Vaccine Research Institute, the meeting brought together epidemiologists, microbiologists, molecular biologists, immunologists and clinicians. All the participants were actively working on different but related aspects of Salmonella and salmonellosis, with most of the leading laboratories worldwide being represented. The workshop provided an excellent opportunity for interdisciplinary consultation; it is not often that the topic of Salmonella and salmonellosis is covered to such breadth and depth in one extended meeting. Keynote addresses by invited speakers were interspersed with offered papers, many by younger members of the scientific community, and this volume presents the collated manuscripts of the lectures and extended summaries of the offered papers.

Download or read book Salmonella written by Maria Teresa Mascellino and published by BoD – Books on Demand. This book was released on 2018-07-18 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the microorganism Salmonella. This bacterium is well known for a long time, being involved in systemic (typhus and paratyphus infections) and nonsystemic diseases such as food poisoning. Major and minor Salmonellae are widespread worldwide in developing countries and industrialized areas, respectively. In 2015, about 3576 Salmonella strains have been isolated from human infections in Italy. S. typhimurium and S. enteritidis are the most prevalent serotypes and represent 80% of cases of infections over the last 10 years. The antibiotic susceptibility decrease over the last decades is a big issue in the management of this bacterium, once considered easy to treat. The use of antibiotic combinations in order to overcome the microorganism resistance should be hoped.

Download or read book Antibiotic Resistance Patterns of Salmonella Enterica Serovar Enteritidis Strains Isolated from Broiler Chickens written by Jessica Linder and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmonella enterica, a group of rod-shaped, Gram-negative bacteria is a leading cause of foodborne illness in humans. Although more than 2,600 serovars of the bacteria exist, Salmonella enterica serovar Enteritidis is one of the most common causes of foodborne salmonellosis in humans primarily spread through contaminated shell eggs, egg products, and other poultry products. Antimicrobial resistance among foodborne bacterial pathogens like Salmonella species has become an ongoing public health issue. In order to assess the degree of antibiotic resistance in Salmonella Enteritidis (SE), this study sought to analyze antibiotic resistance patterns and several genes known to be involved in the expression of antibiotic resistance in SE. A total of eighty nine SE isolates recovered from diseased broiler chickens submitted to The Pennsylvania State University's Animal Diagnostic Laboratory were examined for their susceptibility to 26 antibiotics using Kirby Bauer disc diffusion test and for the presence of the marRAB operon (Multiple Antibiotic Resistance) genes, which are known to regulate resistant gene expression in some bacteria, by polymerase chain reaction. The tested isolates were also subjected to pulsed-field gel electrophoresis (PFGE) to determine if there is any association between PFGE fingerprint patterns and antimicrobial resistance profiles of SE. Although all the isolates contained the marRAB operon genes, only very few isolates (4.49%) showed any resistance to the antibiotics used in the study. Furthermore, no correlation was made between antibiotic resistant profiles and PFGE types. Regardless of the lack of relationships found, the study showed that only a small amount of isolates displayed resistance to antibiotics despite the growing threat of antibiotic resistance. Thus, although antibiotic resistance is a prevalent issue in food animal production, the results obtained showed no significant role of resistance in clinical isolates of SE isolated from broiler chickens.

It provides a candid analysis of the problems with the current system, and outlines the major components of the task at hand: creating workable, streamlined food safety standards and practices.

Download or read book Pathogenomics and Source Dynamics of Salmonella Enterica Serovar Enteritidis written by Matthew Moreau and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmonella enterica serovar Enteritidis (SE) is one of the most frequent common causes of morbidity and mortality in humans due to consumption of contaminated eggs and egg products. The association between egg contamination and foodborne outbreaks of SE suggests egg derived SE might be more adept to cause human illness than SE from other sources. Therefore, there is a need to understand the molecular mechanisms underlying the ability of egg-derived SE to colonize the chicken intestinal and reproductive tracts and cause disease in the human host. To this end, the present study was carried out in three objectives. The first objective was to sequence two egg-derived SE isolates belonging to the PFGE type JEGX01.0004 to identify the genes that might be involved in SE colonization and/or pathogenesis. Both genomes were almost identical (99% identity) being approximately 4.67Mb in size and the GC content was 52%. Both genomes contained about 4,600 open reading frames, of which 600 (or 12.5% of the genome) were related to virulence. Nine genes contained single nucleotide polymorphisms (SNPs) when these virulence-associated genes of egg isolated SE were compared with human isolated SE providing evidence of host-adapted microevolution of SE. Among these SNPs, two resulted in non-conservative changes in a fimbrial usher and a lipopolysaccharide biosynthesis gene, whereas four SNPs were located in promoter regions. The second objective of the study was to identify the host-specific genes (poultry vs. human) by pan-genomic analysis of the newly sequenced genomes and the genomes of Salmonella serovars published in the NCBI database. There were approximately 2, 800 cluster of orthologous genes (COGs) conserved among all serovars tested of which 247 were associated with Salmonella virulence. These core virulence genes may be associated with colonization and/or subsequent infection in all host species whereas the 'host-specific' genes most likely determine the host-specific mechanisms. This analysis identified 10 poultry-specific potential virulence genes, including the genes of two fimbrial operons, lpf- and sti- and four genes with hypothetical functions. Twelve other genes (e. g. iroD, ttrB/C, and sthA) were present only in Salmonella serovars that can infect the human host. The third objective of the study was to elucidate if the source attributes have an effect on SE virulence. Here, the colonization ability and virulence potential of SE grown in Luria broth (LB) medium and egg yolk in the laboratory and SE recovered from feces of mice experimentally infected with SE) were compared using a mouse colitis model of SE infection. The results demonstrated that SE grown in the egg yolk possesses enhanced colonization, shedding, and virulence capabilities as compared to the SE grown in the LB medium or SE recovered from mouse feces as determined by clinical signs, gross pathology, histological lesion scoring, and bacterial enumeration of feces, small and large intestines, and internal organs of the infected mice. These data suggest that egg yolk may condition SE to be better 'primed' for transmission to and infection of a second host by upregulating the expression of certain genes. Future studies should be directed towards understanding the mechanisms involved in microevolution of SE virulence in egg yolk using approaches, such as microarray and RNA sequencing.In conclusion, this study provides new insights into the current understanding of SE virulence and identifies potential targets for rational development of vaccines and antimicrobials to minimize human foodborne illness due to SE.
