The general treatment of enteric fever
… that: (1) There is no specific treatment for Enteric Fever. (2) No drug will shorten its natural course. (3) A strictly antiseptic treatment gives slighty better results than a purely expectant symptomatic treatment. (4) Antipyretic treatment is undesirable and often dangerous. (5) Eliminative …

Small molecule inhibitors against enteric bacterial glycosyltransferases
Enteric bacterial pathogens are the major sources of foodborne diseases. Infection caused by these pathogens leads to gastroenteritis thus of great threat to public health. Pathogenic bacteria evolved to develop various secretion systems to deliver virulence proteins termed ‘effectors’. These …

Factors That Influence Mammalian Enteric Virus Infection
… In addition, a subset of RNA viruses are also enteric pathogens. In particular, these viruses must navigate several environments for transmission and subsequent infection through the fecal-oral route. In this work, I used poliovirus, an enteric RNA virus from the Picornaviridae family, as a …

Aorto-enteric Fistula Following Abdominal Aorta Surgery
<p>Forty-six aorto-enteric fistuiae following abdominal aorta surgery are here recorded. A number of these have never before been recorded in the literature. For the first time sixteen cases of these aorto-enteric fistulae that were subjected to surgical intervention have been tabulated. Twelve of …

Plant-based Multicomponent Vaccines against Enteric Diseases
<p>To generate a plant-based multicomponent oral vaccine against cholera, rotavirus and enterotoxigenic E.coli (ETEC), we have constructed transgenic potato plants that synthesize the cholera toxin B and A2 subunits, the rotavirus enterotoxin NSP4 22 amino acid epitope and the ETEC fimbrial antigen …

Identification of a Novel Role of BMP Signaling in Enteric Neural Crest Colonization of the Zebrafish Enteric Nervous System
The vertebrate enteric nervous system (ENS) consists of a series of interconnected ganglia within the gastrointestinal (GI) tract, formed during development following the migration of enteric neural crest cells (ENCCs) into the primitive gut tube. Much work has been done to unravel the complex …

Molecular Studies of Restriction Genes in Enteric Bacteria
… genes on the chromosome were examined in three enteric bacteria. <em>Salmonella typhimurium</em> LT2, <em>Klebsiella pneumoniae</em> GM 236, and <em>Klebsiella pneumoniae</em> M5al. The 98 minute region of the <em>Salmonella typhimurium</em> LT2 chromosome comprises at least two R-M systems. …

Nitrogen regulation of theput operon in enteric bacteria
Enteric bacteria can grow on proline as the sole nitrogen and carbon source. Expression of the proline utilization (put) operon in Klebsiella aerogenes and Escherichia coli is responsive to nitrogen regulation, but Salmonella typhimurium can not activate put operon expression when growing in medium …

Innate sensing and regulation during enteric caliciviruses infections
Several decades after the discovery of the human norovirus, with thousands of lives and billions of dollars lost, the lack of a robust cell culture system still severely hampers development of vaccines and therapeutics. This is likely in large part as a result of our limited understanding of the …

Factors that affect horizontal gene transfer in enteric bacteria
… that influence the conjugation frequencies of enteric bacteria including Salmonella, E. coli and Enterococcus. We found that the catecholamine norepinephrine (NE) at physiological concentrations enhanced conjugation efficiencies of a conjugative plasmid from a clinical strain of Salmonella …

Neuronal plasticity in the enteric nervous system motor pathways
… underlying neurotransmission within the enteric nervous system are not yet known. Acetylcholine acting on nicotinic receptors mediates the majority of fast synaptic transmission between enteric neurons, however, recent studies suggest that the peristaltic motor pattern can occur during …

The Inhibitory Effects of Acetic Acid on Enteric Bacteria
The surface of a multicellular organism, exposed to the external environment, either directly or indirectly, is inhabited by a specific microbial flora. This holds true regardless of the species or environment of the multicellular organism's The microbial flora of the multicellular organism, man, …

Genetic Control Of Enteric Nervous System Development And Subtype Specification
… and sometimes, early death. In HSCR, the enteric nervous system (ENS) does not develop completely, resulting in a region of bowel lacking neurons. HSCR can be treated by surgically removing aganglionic bowel, but many children with HSCR have poor motility even after surgery, especially …

A cultivable primate calicivirus causes enteric infections in gnotobiotic piglets
Many enteric caliciviruses cause acute gastroenteritis in humans and animals. Examples of these include human norovirus (NoV), human sapovirus, and the newly discovered recoviruses. It is estimated that human NoV accounts for over 95% of nonbacterial acute gastroenteritis worldwide. However, …

The role of enteric bacteria in the Abalone, Haliotis Midae
… in seaweeds which farmed abalone consume. The enteric bacteria were enumerated using culturable and total (DAPI) counts. The numbers of culturable bacteria fell between 3.5x10⁵ and 2.3x10⁸ cfu/g wet weight tissue. The DAPI counts were between 1.6x10⁹ and 5.1x10⁹ cells per gram of tissue. The …

A Molecular Basis for Macrophage Control of Enteric Nervous System Function
… between intestinal macrophages and the enteric nervous system regulate gastrointestinal motility, yet we have an incomplete understanding of the molecular mediators of this crosstalk. Here we identify complement component 1q (C1q) as a macrophage product that regulates gut motility. …

Interplay Between Tryptophan Metabolites and the Virulence Factors of Enteric Pathogens
… molecules in dictating the infectivity of an enteric pathogen remains unknown. Because the concentrations of these small molecules naturally present in the body are in the range of the drug concentrations that are used to treat certain diseases, it is possible to repurpose the information …

The Molecular Epidemiology of Enteric Fever in South and Southeast Asia
… systemic infection caused by <i>Salmonella enterica</i> sub-species <i>enterica</i> serovars Typhi (<i>S.</i> Typhi) and Paratyphi A (<i>S.</i> Paratyphi A). While the disease is mainly travel-associated in developed countries, it still causes significant burden in the poorest areas in …
