Abstract:
E. coli are the predominant microorganisms in the human gastrointestinal tract. In most cases, they exist as harmless comensals, and some of them are beneficial to their host in balancing gut flora and absorption of nutrients. However, there are pathogenic strains that cause a broad range of diseases in humans and animals, from diarrhea to bloodstream infections. Among bacterial strains causing these symptoms, seven pathotypes are now recognized: enteropathogenic E. coli (EPEC), shiga toxin-producing E. coli (STEC), enterotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC), enteroaggregati

Abstract:
Zoonoses are currently a public health problem, therefore research on the infectivity of zoonotic pathogens is extremely important. One of the vectors of zoonoses are reptiles, which are a reservoir of many path- ogens, including viruses, bacteria, fungi, protozoa, and parasites. Therefore, both free-living reptiles and those bred as a hobby, illegally transported from exotic countries or belonging to zoo collections may be a source of infectious diseases. The most common reptilerelated zoonoses are salmonellosis. Reptiles may also be a reservoir of other pathogenic intestinal bacteria, such a

Abstract:
Escherichia coli is a representative of the natural normal microflora of humans and animals. At the same time, some variants may acquire pathogenic properties that contribute to the occurrence of intestinal and extraintestinal infections. In the pathogenesis of these diseases, the main role is played by exotoxins. Currently, along with the well-known and well-studied toxins of Escherichia coli, there is information about new toxoid structures detected in this pathogen, which play an important role in pathologies in humans and animals. Authors summarized current data on the toxigenic properties

Abstract:
Foodborne outbreaks of infectious disease caused by enteropathogenic E coli O157 have occurred throughout Japan since 1996. This study was undertaken to check whether commonly used chlorination could effectively inactivate E coli O157 in water. Pathogenic E coli 157 could be as easily inactivated by chlorine as non-pathogenic E coli K12. Although the presence of suspended solids (&amp;lt;5mg/L) reduced the rate of E coli inactivation, waters obtained from properly operated treatment systems, including chlorination, would be safe against pathogenic E coli O157.

Abstract:
Avian Pathogenic Escherichia coli (APEC) is an important pathogen of the poultry industry, responsible for 43% of condemnations of broiler birds at slaughter and annual losses of between 1-8% of a laying flock. APEC is also a public health concern; consumption of poultry meat has been linked with urinary tract infections (UTI) in humans, and also as a reservoir of potential antimicrobial resistance genes. In this study of strain 3770, a reproductive tract associated isolate of APEC, the isolate was characterised for typical APEC virulence phenotypes, and also underwent full-genome sequencing i

Bacterial diarrhoeal diseases have significant influence on global human health, and are a leading cause of preventable death in the developing world. Enterohaemorrhagic Escherichia coli (EHEC), pathogenic strains of E. coli that carry potent toxins, have been associated with a high number of large-scale outbreaks caused by contaminated food and water sources. This pathotype produces diarrhoea and haemorrhagic colitis in infected humans, and in some patients leads to the development of haemolytic uremic syndrome (HUS), which can result in mortality and chronic kidney disease.

Abstract:
Fireblight, a disease of apples and pears, is caused by Erwinia amylovora. Mutants of E. amylovora that do not produce the extreacellular polysaccharide (EPS), amylovoran, are avirulent. A similar EPS, stewartan, is produced by E. stewartii, which caused Stewart's wilt of corn, and which has also been implicated in the virulence of this strain. Both stewartan and amylovoran are type 1 capsular polysaccharides, typified by the colanic acid slime produced by Escherichia coli. Extracellular polysaccharide slime and capsules are important for the virulence of bacterial pathogens of plants and anim

Abstract:
Fungal plant pathogens are responsible for extensive annual crop and revenue losses throughout the world. To better understand why fungi cause diseases, we performed gene-disruption mutagenesis on several pathogenic Colletotrichum species and demonstrated that pathogenic isolates can be converted to symbionts expressing non-pathogenic lifestyles. One group of nonpathogenic mutants confer disease protection against pathogenic species of Col!etotrichum, Fusarium and Phytophthora; drought tolerance; and growth enhancement to host plants. These mutants have been defined as mutualists and disease r

Abstract:
The current Food Standards Agency consumer guidance states that consumers can freeze pre-packed food right up to the “use-by” date and, once food has been defrosted, it should be consumed within 24 hours. This strategic review has collated relevant data to determine whether there is an increased risk in relation to freezing ready-to-eat and non-ready-to-eat foods on the use-by date compared to the day before the use-by date. The review has focused on how the shelf-life of a food is determined and the effects of freezing, thawing and refrigeration on foodborne pathogens, including Bacillus spp.

Role of Proteins Secreted by the Hrp-Pathways of Erwinia stewartii and E. herbicola pv. gypsophilae in Eliciting Water-Soaking Symptoms and Initiating Galls. United States Department of Agriculture, 2001. http://dx.doi.org/10.32747/2001.7580675.bard.

Full text
Abstract:
Many bacterial pathogens of plants can inject pathogenicity proteins into host cells using a specialized type III secretion system encoded by hrpgenes. This system deliver effector proteins, into plant cells that function in both susceptible and resistant interactions. We have found that the virulence of Erwinia stewartii(Es; syn. Pantoea stewartii) and Erwinia herbicola pv. gypsophilae (Ehg, syn. Pantoea agglomerans), which cause Stewart's wilt of corn and galls on Gypsophila, respectively, depends on hrpgenes. The major objectives of this project were: To increase expression of hrpgenes in o

Abstract:
Rapid detection of pathogens and hazardous elements in fresh fruits and vegetables after harvest requires the use of advanced sensor technology at each step in the farm-to-consumer or farm-to-processing sequence. Fourier-transform infrared (FTIR) spectroscopy and the complementary Raman spectroscopy, an advanced optical technique based on light scattering will be investigated for rapid and on-site assessment of produce safety. Paving the way toward the development of this innovative methodology, specific original objectives were to (1) identify and distinguish different serotypes of Escherichi

Full text
Abstract:
Qurbani is a religious practice that takes place during Eid al-Adha. Consumers practicing Qurbani typically wish to collect meat and red offal within a short time after slaughter, which means these products cannot complete normal chilling processes before leaving the slaughterhouse. This could permit greater growth of pathogens and has the potential to increase the risk of consumer illness. The FSA is working with industry and stakeholder groups to ensure that the risk to consumers under these conditions remains at an acceptable level. To help inform these discussions, the FSA commissioned thi
