Through a series of steps called the immune response, the immune system attacks organisms and substances that invade body systems and cause disease.The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. The cells involved are white blood cells, or leukocytes, which come in two basic types that combine to seek out and destroy disease-causing organisms or substances. When antigens (foreign substances that invade the body) are detected, several types of cells work together to recognize them and respond. These cells trigger the B lymphocytes to produce antibodies, specialized proteins that lock onto specific antigens. Once produced, these antibodies continue to exist in a person`s body, so that if the same antigen is presented to the immune system again, the antibodies are already there to do their job. So if someone gets sick with a certain disease, like chickenpox, that person typically doesn`t get sick from it again. ····· 10361132927

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Neisseria meningitidis is a facultative microaerophilic bacterium that can utilize oxygen, nitrite, and nitric oxide as terminal electron acceptors for its respiration. Oxygen can cause oxidation of both c-type and b-type cytochromes while nitrite or nitric oxide cause oxidation of b-type cytochrome predominantly. Nitrite as well as nitric oxide can directly inhibits oxidation of c-type cytochromes by oxygen. The meningococcus posseses many periplasmic electron transferring proteins. These proteins include cytochrome c2, cytochrome c4, cytochrome c5, and lipid-modified azurin. The cytochromes c2 and c4 are major electron donors to cytochrome cbb3 oxidase whereas the cytochrome c5 is a major electron donor to copper-containing nitrite reductase. The cytochrome c5 and lipid-modified azurin, to lesser extent, are also able to donate electrons to cytochrome cbb3 oxidase.

The excessive accumulation of these heavy metals can modify essential protein structure or replace an essential element causing chlorosis, growth impairment, browning of roots, and inactivation of photosystems. Also the ingestion of contaminated food or drinking water can expose humans and animals to toxic levels of the heavy metals. Recently, the use of biological materials for effective remediation of heavy metals, often termed bioremediation, from metal contaminated sites has emerged as a potential alternative to conventional treatment techniques. Bioremediation is a process that uses microorganisms or their enzymes to detoxify these contaminants and keep the environment free from these contaminants. Microorganisms and plants are usually used for the removal of these heavy metals.

How to improve phosphorus fertilizer efficiency and utilize the potential nutrient in soil has therefore, long been a major concern for field practitioners. This has led to a search for eco-friendly and economically attractive alternative technology for improving crop production in low or even P deficient soils. In this context, natural soil inhabitants endowed with P-solubilizing activity, often termed phosphate-solubilizing microorganisms [PSM], provides a viable substitute to chemical P fertilizers. Inoculation of phosphate-solubilizing microorganisms, like, bacteria and fungi in soil has been shown to immensely affect the growth of plants by making not only P available to plants but also facilitate the growth of plants by other mechanisms leading to higher crop yields. ····· 10361131808
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Honey is an old remedy recently rediscovered as a possible alternative to modern antibiotics in wound management but its mode of action is not fully understood. The antibacterial activity of honey can be divided into hydrogen peroxide and non-hydrogen peroxide-derived activity. This later type of activity is characteristic of honeys from Australasia (e.g. manuka honey) and preferred for wound management, although historically local honeys have been used. The main aim of this study was to investigate the mechanisms of antibacterial action of manuka honey, but also other local honeys. This work shows that the non-peroxide activity is also found in local honeys and that the antibacterial activity of honey on wound infecting microoganisms is distinct in terms of targets of activity. For Gram negative it seems to act by physically disrupting the cell wall, whilst for Gram positive is appears to have physiological effect on cellular processes such as cytokinesis. By the end it was possible to elucidate some of the aspects that make this natural product atractive for modern medical use. ····· 10361119780

A study of pathogenic Escherichia coli in Sarda sheep at slaughter, on carcasses, fleeces, gut and faeces was performed. Nineteen sampling sessions were carried out in industrial capacity slaughterhouses. The aim of the present study was to evaluate the role of the sheep as STEC reservoir and to detect the prevalent serogroups over the sheep chain production. In order to make a preliminary screening of STEC in collected samples, a simplex PCR was performed on all the specimens. Virulence profile characterization of the isolates showed a significant level of STEC strains (22.6%) and a higher number of EPEC (53.8%). Furthermore, virulence accessory factors are widely detected, assigning an additional pathogenic capacity to the strains, and very complex virulence profiles. Serotyping assays proved that Sarda sheep carried mainly non-O157 E. coli, including O91 serogroup, the role of these pathogroup in Public Health must not be underestimated. ····· 10361119654

The clinical isolates of Mycobacterium tuberculosis (47 ofloxacin- susceptible and 71 ofloxacin-resistant) strains obtained from individual patients from various parts of India were analyzed for gyr A mutation in quinolone resistant determining region (QRDR). Most of the mutations were seen clustered in the codons 90, 94 and 95, which is a hot spot region of QRDR. The types of mutations were correlated with the in vitro susceptibility pattern of the strains to ofloxacin. The resistance to fluoroquinolones was observed predominantly due to gyr A mutations. Gyr A being a gene with house keeping functions, is highly conserved in various mycobacterial species. It was adapted for PCR-RFLP assay using gyr A gene to see the difference in the profile of 23 standard species of mycobacteria.

A virus that preys on bacteria is called a bacteriophage. The main reason to learn about virus is to shield ourselves from being infected by them in the emergence of a viral epidemic or, perhaps, to live with them accommodatingly. We learned about the existence of virus just a little more than a century ago and new facts about them keep turning up all the time. There is still a great deal that we do not know about virus. We cannot produce a vaccine against viral infections such as HIV with the same concept that led to the dicovery of the first vaccine, for Smallpox, by Janner. Whether this drawback is due to the complexity of individual virus or the continued lack of certain basic knowledge of viral nature, no one can say.
