Neonatal meningitis is transmitted to the foetus postpartum, and although it is not exceedingly prevalent, and is treatable, it is still considered a serious disease and prevention is preferred over treatment. The strain of E. coli which is responsible for the infection is found naturally in humans and is usually non-virulent. Most neonatal E. coli meningitis infections occur during parturition, so whether the mothers diet will influence the susceptibility of the neonate is uncertain. Infection may also occur in the hospital or at home, and is more likely to occur in an immunocompromised child. Premature and low-birth-weight babies are most susceptible. It should also be noted that in the UK and Ireland, under 20% of neonatal meningitis are the result of E. coli. The majority of cases are the result of group B streptococcal (GBS) meningitis. In less developed countries, however, E. coli is the dominant cause of the disease. If the natural antibiotics used in this investigation are effective, ...

Declining hormone levels with age affect the brain. In the brain, key hormones improve energy metabolism, protect brain cell membranes, and help maintain levels of acetylcholine.

Baby Health: Fattening up your babys brain. Babies need to have a high-fat intake to ensure that they are provided with enough energy to be active and to develop brain cell membranes that protect each of the nerves.

The results of such studies will not only serve future space travel but also provide information for a better life on earth. For example, data from the experiments can provide insights about the radiation risks on earth and help improve radiation therapies for treating cancer.. In the past year a committee of experts, the so-called Topical Team for ESA under the coordination of Prof. Marco Durante (TIFPA) and Dr. Jennifer Ngo-Anh (ESA), initiated the new programme. The IBER (2017) program has then been confirmed by the ESA and GSI management on July 3rd, 2017. The call was released from ESA on 10th of August. As a result of the call, ESA received 21 applications (letters of intent) from research groups all over Europe. The applicants have been invited to an information workshop at GSI.. At the workshop, the participants discussed the various project ideas and their feasibility. The researchers are now prepared to submit detailed proposals, which a committee of experts will decide on by the end ...

The neurotoxic potential of intravenous administered benzylpenicillin (BPC) was studied in rabbits with intact blood-CNS barriers and rabbits with experimental E. coli meningitis. At onset of epileptogenic EEG activity or seizures, serum, CSF and brain tissue were collected for assay of BPC. Based on the fact that, in tissues, BPC seems to remain extracellularly, brain concentrations of BPC were expressed as brain tissue fluid (BTF) levels, calculated as lOx the concentration in whole brain tissue. Neurotoxicity could be precipitated in all rabbits. In normal rabbits BTF levels of BPC were considerably higher than those in CSF indicating a better penetration across the blood-brain barrier (BBB). BPC penetrated better to CSF and BTF in meningitic rabbits than in normal controls, suggesting some degree of damage of the BBB concomitant with meningeal inflammation. E. coli meningitis did not increase the neurotoxicity of BPC. In control rabbits the intracistemal injection of saline resulted in some ...

A research team at BGUs Landau Family Microalgal Biotechnology Lab in the Jacob Blaustein Institutes for Desert Research (BIDR) headed by Prof. Zvi HaCohen, is studying an algal mutant that is capable of accumulating up to 15 percent (of dry weight) of a polyunsaturated fatty acid (PUFA) called DGLA (Dihomo-ã-Linolenic Acid). The new strain, IKG-1, is a freshwater microalga that the researchers believe is the only known plant source capable of producing such significant amounts of DGLA. Omega-6 PUFA are necessary as components of brain cell membranes and have various nutritional uses, explains HaCohen, incumbent of the Maks and Rochelle Etingin Chair in Desert Research and rector-elect at BGU. DGLA is one of these PUFA, but appears in nature only as an intermediate in the biosynthesis of other compounds and does not accumulate to any appreciable concentration. There is no natural source for DGLA and although its beneficial effects are well known, very few clinical studies have been ...

Still not convinced? Fats can also influence brain development and performance, especially at either end of life -- growing infants and elderly people. In fact, there are two windows of time in which the brain is especially sensitive to nutrition: the first two years of life for a growing baby and the last couple decades of life for a senior citizen. Both growing and aging brains need nutritious fats. The most rapid brain growth occurs during the first year of life, with the infants brain tripling in size by the first birthday. During this stage of rapid central nervous system growth, the brain uses sixty percent of the total energy consumed by the infant. Fats are a major component of the brain cell membrane and the myelin sheath around each nerve. So, it makes sense that getting enough fat, and the right kinds of fat, can greatly affect brain development and performance. In fact, during the first year, around fifty percent of an infants daily calories come from fat. Mother Nature knows how ...

Can sinus infection cause meningitis - I keep reading that its rare for sinus infection to cause meningitis, but it happened to me. If its so rare, how did it happen? Rare. Rare conditions mean that they occur, just in a very small amount of patients.

Blood-brain barrier (BBB) disruption and neuroinflammation are considered key mechanisms of pathogenic Escherichia coli invasion of the brain. However, the specific molecules involved in meningitic E. coli-induced BBB breakdown and neuroinflammatory response remain unclear. Our previous RNA-sequencing data from human brain microvascular endothelial cells (hBMECs) revealed two important host factors: platelet-derived growth factor-B (PDGF-B) and intercellular adhesion molecule-1 (ICAM-1), which were significantly upregulated in hBMECs after meningitic E. coli infection. Whether and how PDGF-B and ICAM-1 contribute to the development of E. coli meningitis are still unclear. The western blot, real-time PCR, enzyme-linked immunosorbent assay, immunohistochemistry, and immunofluorescence were applied to verify the significant induction of PDGF-B and ICAM-1 by meningitic E. coli in vivo and in vitro. Evans blue assay and electric cell-substrate impedance sensing assay were combined to identify the effects of

Structures on the surface of pneumococci determine the ability of these bacteria to enter the brain and cause severe infections, according to a paper published in The Journal of Clinical Investigation by researchers at Karolinska Institutet. Their findings suggest that certain pneumococci that are small in size, and which have a special protein on their surface, can more easily pass through the blood-brain barrier and cause meningitis that may be lethal.

Despite the development of effective vaccines, useful tools for rapid identification of pathogens and potent antimicrobial drugs, neonatal meningitis continues to contribute substantially to neurological disability worldwide. The persistence of neonatal meningitis results from increases in the numbers of infants surviving premature delivery ...

When you are looking to feed your brain directly, reach for this superpower fruit. Avocados contain oleic acid, a fatty acid that is a major component of myelin, a fatty material that protects nerve cells and supports the flow of nerve signals throughout the body, according to Brianna Diorio, nutritionist for The Vitamin Shoppe. The monounsaturated fatty acids found in avocados also help keep brain cell membranes flexible and promote healthy blood flow to the brain. Spread it on toast or add it to your smoothie to create a creamy texture or go with the classic take on avocado and whip up your best guacamole mix. ...

The organisms that cause meningitis usually colonize in a persons respiratory tract and may be transmitted by close contact with persons who may be carrying the infection, or by touching contaminated objects, such as doorknobs, hard surfaces, or toys, and then touching the nose, mouth, or eyes. The organisms may also be transmitted through respiratory secretions from a sneeze, close conversation, or by touching infected matter. The infection usually starts in the respiratory tract and then travels into the bloodstream where it can reach the brain and spinal cord. The organism may first cause a cold, sinus infection, or ear infection (more common in children), and then travel through the sinuses into the brain and CSF, although this method of transmission is less common. A child may have no symptoms at all, but may carry the organism in his/her nose and throat.. ...

N2 - We examined the kinetics of tumor necrosis factor (TNF) production induced by Escherichia coli lipopolysaccharide (LPS) in relation to LPS tolerance and endotoxemic lesions of piglets. The plasma of piglets demonstrated cytotoxicity to TNF-sensitive L929 cells between 0.5 and 4 h after inoculation with 200 μg kg -1 of LPS. This cytotoxicity was neutralized by anti-bovine TNF serum. These piglets had disseminated intravascular coagulation (DIC) and meningoencephalitis. However, if piglets were first treated with three doses of 40 μg kg -1 of LPS, both TNF production and the occurrence of DIC were inhibited when 200 μg kg -1 of LPS was ...

The objective of this study was to characterize the changes in various metabolic parameters in blood and milk during IMI challenge with Escherichia coli (E. coli) for dairy cows during early lactation. Thirty, healthy primiparous Holstein cows were infused (h = 0) with ~20-40 cfu of live E. coli into one front mammary quarter at ~4-6 wk in lactation. Daily feed intake and milk yield were recorded. At -12, 0, 3, 6, 12, 18, 24, 36, 48, 60, 72, 96, 108, 120, 132, 144, 156, 168, 180 and 192 h relative to challenge rectal temperatures were recorded and quarter foremilk was collected for analysis of shedding of E. coli. Composite milk samples were collected at -180, -132, -84, -36, -12, 12, 24, 36, 48, 60, 72, 84, 96, 132 and 180 h relative to challenge (h = 0) and analyzed for lactate dehydrogenase (LDH), somatic cell count, fat, protein, lactose, citrate, beta-hydroxybutyrate (BHBA), free glucose (fglu), and glucose-6-phosphate (G6P). Blood was collected at -12, 0, 3, 6, 12, 18, 24, 36, 60, 72, 84, 132 and

Among the microbial flora that naturally inhabit the human gastrointestinal tract, Escherichia coli is the most abundant facultative anaerobe. While members of the family Enterobacteriaceae are natural inhabitants of the gastrointestinal tract and are abundant in the environment, there are particular predisposing factors and circumstances that allow both intestinal and extraintestinal infections to occur in community and nosocomial settings. In developing countries of Asia, Latin America, and Africa, where diarrhea is one of the most lethal threats to children under the age of five, enteropathogenic E. coli (EPEC) is a major cause of infantile diarrhea. A study describing early predictors of adverse outcomes following neonatal bacterial meningitis found that elevated total protein in the initial cerebrospinal fluid (CSF) analysis, as well as a CSF-to-blood glucose ratio of | 0.5, corresponded with an adverse outcome. The current definition of postinfectious irritable bowel syndrome (IBS) according to

Omega-3 fatty acids have many health benefits. They are essential fatty acids that cannot be synthesized by the body. Omega-3s come from plant origins such as hemp and flaxseed and animal origins such as fish oil in salmon, sardines and tuna. However, different forms of Omega-3 fatty acids come from each source. Most of their health benefits are attributed to docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) which are obtained from animal origin. Brain health: Omega-3 fatty acids build the brain cell membranes and are essential to brain health. Those who administer Omega-3 sufficiently have more functional brains and better memory. Omega-3 can protect from age-related brain disorders such as dementia. Depression: Low levels of Omega-3 were found to be associated with depression and even self-harm. Omega-3 supplements were found to help with mood swings and mild to moderate levels of depression. Some studies found that Omega-3 can also be helpful in the cases of depression during ...

How serious is bacterial meningitis?. If it is diagnosed early and treated promptly, the majority of people make a complete recovery. In some cases it can be fatal or a person may be left with a permanent disability, such as deafness, blindness, amputations or brain damage (resulting in mental retardation or paralysis) even with prompt treatment.. How is bacterial meningitis spread?. Fortunately, none of the bacteria that cause meningitis are as contagious as diseases like the common cold or the flu, and they are not spread by casual contact or by simply breathing the air where a person with meningitis has been. The germs live naturally in the back of our noses and throats, but they do not live for long outside the body. They are spread when people exchange saliva (such as by kissing; sharing drinking containers, utensils or cigarettes).. The germ does not cause meningitis in most people. Instead most people become carriers of the germ for days, weeks or even months. Being a carrier helps to ...

Glioblastomas are largely unresponsive to all available treatments and there is therefore an urgent need for novel therapeutics. Here we have probed the antineoplastic effects of a bacterial protein toxin, the cytotoxic necrotizing factor 1 (CNF1), in the syngenic GL261 glioma cell model. CNF1 produces a long-lasting activation of Rho GTPases, with consequent blockade of cytodieresis in proliferating cells and promotion of neuron health and plasticity. We have tested the antiproliferative effects of CNF1 on GL261 cells and human glioma cells obtained from surgical specimens. For the in vivo experiments, we injected GL261 cells into the adult mouse visual cortex, and five days later we administered either a single intracerebral dose of CNF1 or vehicle. To compare CNF1 with a canonical antitumoral drug, we infused temozolomide (TMZ) via minipumps for 1 week in an additional animal group. In culture, CNF1 was very effective in blocking proliferation of GL261 cells, leading them to multinucleation,

Yes, some forms of bacterial meningitis are contagious. The bacteria are spread through the exchange of respiratory and throat secretions (i.e., coughing and kissing). Fortunately, none of the bacteria that cause meningitis are as contagious as things like the common cold or the flu, and they are not spread by casual contact or by simply breathing the air where a person with meningitis has been.. However, sometimes the bacteria that cause meningitis have spread to other people who have had close or prolonged contact with a patient with meningitis caused by Neisseria meningitidis (also called meningococcal meningitis) or Hib. People in the same household or day care center, or anyone with direct contact with a patients oral secretions (such as a boyfriend or girlfriend) would be considered at increased risk of acquiring the infection. People who qualify as close contacts of a person with meningitis caused by N. meningitidis should receive antibiotics to prevent them from getting the disease. ...

Meningitis itself isnt a disease, just a description meaning that the tissues around the brain and spinal cord have become inflamed. In the United States, bacterial infections can cause meningitis, as can enteroviruses, mumps and herpes simplex. But a high proportion of cases have, as doctors say, no known etiology: No one knows why the patients brain and spinal tissues are swelling.. This was the case with the Dhaka outbreak. C.H.R.F. is one of the premier microbiology labs in Southeast Asia and is in charge of tracking meningitis in the country for the World Health Organization. Every meningitis case that comes in, we culture, Saha told me. We do antigen tests for pneumococcus, Neisseria meningitidis, Hemophilus influenzae and G.B.S., or Group B streptococcus - the four infections most likely to cause meningitis. Then we do a much more sensitive and specific test for Streptococcus pneumoniae bacteria, since that causes the highest proportion of cases. And then we also do real-time ...

Meningitis is an inflammation of the fluid that covers the brain and spinal cord. It is an extremely serious condition that can result in death. Although anyone can develop meningitis, those most at risk are children under five and adolescents between 15-19 years old.. There are two main kinds of meningitis:. Bacterial meningitis is the more severe form of the disease and requires treatment in a hospital setting. Viral meningitis is more common, and most people with this form of the illness get better in a couple of weeks. With mild cases, you may only need home treatment, including taking medicine for fever and pain and drinking enough fluids to stay hydrated.. Meningitis isnt as contagious as viruses, such as those that cause the common cold, but it can spread from person to person via coughing, sneezing, kissing, sexual contact, or contact with infected blood or stool. A mother can also pass the germs that cause meningitis to her baby during birth.. Meningitis can be hard to diagnose because ...

We took our first test in Disease, Immunology, and Therapeutics this week. It was one of those tests that I felt confident going into, but coming out I felt fortunate to pass. As it was I scored around average at 83%. Since the test we have been focusing more on individual microorganisms such as Staphylococcus aureus, Streptococcus pyogenes, Neisseria meningitidis, etc. You might recognize the diseases they cause. S. aureus causes staph infection (among other things), S. pyogenes causes strep throat, and N. meningitidis causes meningitis.The idea is to differentiate them from each other and to understand the virulence factors - what it is about each organism that makes them able to not only survive but thrive within a host. ...
