Abstract:
ABSTRACT Interleukin-10 (IL-10) and IL-12 are two cytokines secreted by monocytes/macrophages in response to bacterial products which have largely opposite effects on the immune system. IL-12 activates cytotoxicity and gamma interferon (IFN-γ) secretion by T cells and NK cells, whereas IL-10 inhibits these functions. In the present study, the capacities of gram-positive and gram-negative bacteria to induce IL-10 and IL-12 were compared. Monocytes from blood donors were stimulated with UV-killed bacteria from each of seven gram-positive and seven gram-negative bacterial species representing bot

Tackling antimicrobial resistance (AMR) is a national and global priority. Despite this, much of our understanding of the epidemiology and transmission of AMR outside the hospital, and thus, how we might control it, remains limited. Long term care facilities (LTCFs) play an important role in the care of older people. However, there have been few studies of the epidemiology and transmission of AMR in this setting. LTCF residents present with frequent co-morbidities which increase their risk of hospitalisation and of AMR infection. LTCFs also offer opportunities for transmission of AMR strains d

Many anaerobic bacteria possess virulence factors that facilitate their pathogenicity (e.g. histolytic enzymes and various toxins). A putrid odour of the affected tissue or drainage is highly suggestive of an anaerobic infection, as is the presence of gas in tissues. Aside from supportive care, treatment requires drainage of abscesses and resection of devitalized tissue; and antibiotics—agents that are active against anaerobes include clindamycin, metronidazole, vancomycin, β‎-lactam/β‎-lactamase inhibitor combinations, carbapenems, moxifloxacin, tigecycline, chloramphenicol, and even macrolides.

Tetanus is a nervous system disorder characterized by intense, painful muscle spasm caused by Clostridium tetani. Tetanus is prevalent in developing countries, but it is rare in developed nations owing to universal childhood vaccination. Common modes of acquisition are puncture wounds, gunshot wounds, burns, compound fractures, and contaminated or unsterile injections. Botulism is a neuroparalytic syndrome caused by neurotoxin produced by Clostridium botulinum. The US Food and Drug Administration approved botulinum toxin for treatment of neuromuscular disorders, including blepharospasm, strabismus, and torticollis, and for many cosmetic procedures.

Abstract:
Chromium-like heavy toxic metals seriously influence the metabolism of living organisms and cause permanent threatening of health. Microorganisms can help to detoxify those hazardous heavy metals in the environment by the process of bioremediation. Two bacterial genera were isolated from industrial sludge designated P1 and P2. From the 16srRNA study, it is revealed that P1 is Bacillus cereus and P2 is Enterobacter sp. They are deposited in NCMR and NCBI and received the accession no. MCC 3868 for P1 and MCC 3788 for P2. P1 is gram positive, motile, and P2 is gram negative, motile. Eighteen antibiotics have been taken for antibiotic assay; P1 is resistant to 12; P2 is resistant to 8 antibiotics. For growth pattern analysis in chromium, three parameters have been selected, and they are temperature, pH, and biomass. In LD50 and above parameters, total chromium uptake by those bacteria in stressed conditions have been recorded. The two bacteria are not antagonistic to each other so they are used to bioremediate chromium from their contaminated sites and also treated as consortium.

Abstract:
In this study, the antibacterial behavior of differing sized graphene quantum dots (GQDs) was studied. The gram negative bacteria, Escherichia coli (E. coli), were used as the bacteria mode. Different sized GQDs with tunable fluorescent colors were acquired by a gel-filtration method. The size, surface chemistry, and photoluminescence properties of GQDs were characterized, respectively. The viability of GQDs treated bacteria was determined by the standard plate counting method. Moreover, the reactive oxidative species (ROS) level was detected by the 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltet

Abstract:
The rhizosphere soil of medicinal plants is rich in microorganisms that develop antibiotics as natural mechanism of protection against other microbes that live in their vicinity. The present study aims to explore the production of antibacterial agents from rhizosphere soil bacteria of 11 medicinal plants and determine their activity against Gram-negative (Pseudomonas aeruginosa, Escherichia coli) and Gram-positive (Bacillus cereus, Staphylococcus aureus) bacteria. Soil samples were collected and used to isolate antibiotic producing bacteria (APB). Those isolates (108) were first tested using C

Abstract:
Disseminated intravascular coagulation (DIC) and multiple organ failure (MOF) are critical consequences of septic patients but the pathogenesis has not been fully elucidated yet, because of the complexities of clinical cases. Thereby, attempts were made to establish animal model with DIC &amp; MOF without injecting endotoxin, bacteria or procoagulants into circulation, which may result in misleading conclusions. Twenty four male Japan albino rabbits were divided into the following 4 groups; [A]-ligation of bile duct and instillation of fecal suspension ( appr. 2 X 107 gram negative rods)into t

Abstract:
In 1982, a protein component that inhibits the limulus coagulation cascade was found in the hemocyte lysates from Japanese and American horseshoe crabs and named anti-lipopolysaccharide (LPS) factor. This protein specifically inhibited the LPS-mediated activation of limulus factor C and had a strong anti-bacterial effect on the growth of Gram-negative R-type bacteria. Moreover, it had a hemolytic activity on the red blood cells sensitized with LPS.In the present study, the complete amino acid sequence of anti-LPS factor purified from the Limulus (L) polyphemus hemocytes was determined by chara
