The onset of Alzheimer's disease (AD) is accompanied by a complex and distributed pattern of neuroanatomic change, difficult to distinguish clinically from dynamic alterations in normal aging. Extreme variations in the sulcal patterns of the human cortex have made it difficult to identify diffuse and focal variations in cortical structure in neurodegenerative disease. We report the first compre...

BACKGROUND Petroleum reservoirs have long been known as the hosts of extremophilic microorganisms. Some of these microorganisms are known for their potential biotechnological applications, particularly production of extra and intracellular polymers and enzymes. OBJECTIVES Here, 14 petroleum liquid samples from southern Iranian oil reservoirs were screened for presence of biosurfactant-produci...

Sir, Recently, a new carbapenemase, NDM-1, encoded by blaNDM-1, has become a global concern. Previous work reported the prevalence of blaNDM-1 mainly in animal-associated and human-associated bacteria (e.g. patients and animals – ). Walsh et al. detected blaNDM-1 in seepage samples and drinking water, indicating the dissemination of blaNDM-1 in the environment. Soil, one of the largest natural ...

Thirteen commercial probiotic feed products were examined for microbiological content and the results were compared with the information available on the product labels. Antibiotic resistance of Lactobacillus and Bacillus was investigated. All the products were inaccurately labelled in either numbers or species of bacteria. Misnaming at the species level was the most common flaw. Lactobacillus ...

Xylella fastidiosa (Xf) subsp. Pauca causes citrus variegated chlorosis (CVC) disease in Brazil, resulting in significant production losses in the citrus industry. Xf is mainly transmitted by three species of sharpshooters (Hemiptera: Cicadellidae) in Brazil; Dilobopterus costalimai (Young), Acrogonia citrina Marucci & Cavichioli and Oncometopia facialis (Signoret). We identified bacterial comm...

Although ubiquitous, bacteria of the Weissella genus are not given sufficient attention. Many members of the genus were originally classified as Leuconostoc or Lactobacillus. With the development of molecular methods, these phylogenetically closely related bacteria formed a separate group, the Weissella genus. Due to its heterofermentative metabolism, Weissella spp. may cause considerable damag...
