| Five species of edible mushrooms, Lentinula edodes, Pleurotus ostreatus, Pholiota nameko, Macrolepiota bonaerensis and Agaricus blazei, were tested for their potential to inhibit the in vitro growth of the pathogenic yeast Candida albicans. Only L. edodes had a fungistatic effect on this human pathogen. The inhibitory compound was produced intra and extracellularly in submersed L. edodes culture, and was also present in fresh and dehydrated mushroom basidiocarps. The fungistatic compound was heat sensitive and lost activity after 72 hours. |

| While the routine use of antibiotics for infectious diarrhea in children must be avoided, because it brings little benefit in most cases and is associated with the risk of increasing antimicrobial resistance, selected cases may require antimicrobial therapy, and the choice of the antimicrobial agent often has to be made empirically. Physicians prescribing antimicrobials in such a setting have not only to be aware of the most likely pathogens, but also of their characteristic antimicrobial susceptibility pattern and the safety profile of the various drugs. We reviewed the literature on the use of ampicillin, beta-lactamase inhibitors, trimethoprim-sulfamethoxazole, chloramphenicol, tetracyclines, nalidixic acid, fluoroquinolones, third-generation... |

| Streptomyces is a genus of Gram-positive bacteria that grows in various environments, and its shape resembles filamentous fungi. The morphological differentiation of Streptomyces involves the formation of a layer of hyphae that can differentiate into a chain of spores. The most interesting property of Streptomyces is the ability to produce bioactive secondary metabolites, such as antifungals, antivirals, antitumorals, anti-hypertensives, immunosuppressants, and especially antibiotics. The production of most antibiotics is species specific, and these secondary metabolites are important for Streptomyces species in order to compete with other microorganisms that come in contact, even within the same genre. Despite the success of the discovery of antibiotics,... |

| ABSTRACT: Microbial resistance is a serious public health problem, which has led to the search for alternative treatments to replace antibiotics, including studies to evaluate the antimicrobial potential of species in Brazil’s Cerrado. Therefore, the present study aimed to evaluate the antimicrobial activity of hydroalcoholic extracts of genipap, baru, and taruma against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans using disc diffusion tests and microdilution. Results indicated that all genipap extracts showed inhibition zones and minimum inhibitory concentrations (MICs) and minimum microbicidal concentrations (MMCs) ranging between 150μg/mL and 940μg/mL against all microorganisms tested. Baru pulp extracts... |

| Clostridium perfringens is a normal inhabitant of the intestinal tract of chickens as well as a potential pathogen that causes necrotic enteritis and colangio hepatitis. The minimum inhibitory concentration (MIC) of seven different compounds used for therapy, growth promotion or prevention of coccidiosis was determined by agar dilution method for 55 C. perfringens strains isolated from the intestines of broiler chickens. All strains showed high susceptibility to penicillin, avilamycin, monensin and narasin. Only 7.3% of the strains showed an intermediated sensitivity to lincomycin, and 49 (89.1%) were considered susceptible. For tetracycline and bacitracin, 41.8% and 47.3% of strains, respectively, were considered resistant. |

| La Antártica se ha constituido en una región de gran interés científico debido a las condiciones extremas que allí se presentan, en especial, de temperatura y radiación ultravioleta. En el campo de la microbiología, las investigaciones se han enfocado, principalmente, en el estudio de la biodiversidad bacteriana, lo que ha llevado a la descripción de nuevas especies, y también gran interés ha despertado la producción de compuestos con aplicaciones biotecnológicas. Entre éstos se encuentran los que pudieran presentar actividad antibacteriana, de gran importancia debido a que uno de los mayores problemas de los últimos años es la emergencia de patógenos intrahospitalarios con una amplia resistencia a los agentes antibacterianos disponibles, no existiendo... |

| The increasing use of antibiotics has led to the development of drug-resistant microorganisms. The emergence of resistant strains has compromised the treatment and control of infectious diseases. As a result, the search and development of a novel class of antibiotic drugs are required. Actinomycetes have been recognized as a richest source of secondary metabolites including antibiotics. The aim of this study was to investigate the diversity of antibiotic-producing soil Actinomycetes from dry dipterocarp forest in Northeast of Thailand. The soil from this area has been known for its poor in nutrients and highly acidic with pH values around 4.5. In such a harsh condition, soil-inhabiting Actinomycetes elevate their protective mechanisms by inducing the... |

| The NAHMS Cattle on Feed Evaluation (COFE) was designed to provide both participants and the industry with information on the nation's feedlot animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid producer sample (3,214 producers) to provide inferences to the nation's feedlot animal population. Included in the study were 13 states that accounted for 85.8 percent of the U.S. cattle-on-feed inventory as of January 1, 1994. State and Federal Veterinary Medical Officers (VMO's) collected data from feedlots of 1,000 head or more capacity through personal interviews from October 3 through December 21, 1994, for Part II.
