For the first time, the presence of a ferulic acid esterase (FAE) was demonstrated in Streptomyces ambofaciens. This extracellular enzyme was produced on a range of lignocellulosic substrates. The maximal level of activity was detected in the presence of either destarched wheat bran or oat spelt xylan as the sole ...

Organic aggregates (OA) in aquatic ecosystems harbour diverse microbial communities. The colonization and growth of OA-attached bacteria are important processes in the degradation and transformation of the particles. The development of efficient and comparative DNA extraction methods is one of the most critical steps in the study of the composition ...

Naturally competent bacteria such as the plant pathogen Ralstonia solanacearum are characterized by their ability to take up free DNA from their surroundings. In this study, we investigated the efficiency of various DNA types including chromosomal linear DNA and circular or linearized integrative and (or) replicative plasmids to naturally transform ...

In Pseudomonas aeruginosa, flavohemoglobin (Fhp) and its cognate regulator FhpR (PA2665) form a protective regulatory circuit, which responds to reactive nitrogen species and is also capable of protecting cells against nitrosative stress. Recently, it has been shown that the expression of the fhp promoter is regulated not only by FhpR, ...

Lactobacilllus casei CRL 431 has the ability to modulate the local and systemic immune responses, which are significantly involved in liver injury caused by hepatotoxins. This work was conducted to determine whether L. casei has a preventive effect on the hepatic damage undergone during an acute liver injury (ALI). Methods: ...

With PCR-denaturing gradient gel electrophoresis analysis, two bacterial 16S rRNA gene V3 region sequences, 7A and 7B, were detected in association with the crushed spores of the arbuscular mycorrhizal fungus Gigaspora margarita W.N. Becker & I.R. Hall 1976 MAFF520054. DNA sequencing and phylogenetic analysis revealed that 7B was mostly related ...

Enteropathogenic Escherichia coli (EPEC) infections are a leading cause of infantile diarrhea in developing nations. Multilocus sequence typing (MLST) characterizes bacterial strains based on the sequences of internal fragments in housekeeping genes. Little is known about strains of EPEC analyzed by MLST from Brazil. In this study, a diverse collection ...

The objective of the present work was to evaluate the relevance of the 2-methylcitric acid cycle (2MCC) to the catabolism of propionate in Burkholderia sacchari. Two B. sacchari mutants unable to grow on propionate were obtained: one disrupted in acnM, and the other in acnM and prpC deleted. An operative ...

We have previously reported that vaccination with CpG oligodeoxynucleotides delivered concomitantly with live Leishmania major (Lm/CpG) eliminates lesions associated with live vaccination in C57BL/6 mice. The absence of lesions is at least in part a result of the CpG DNA-mediated activation of dermal dendritic cells to produce cytokines such as ...

The global gene expression and biomolecular composition in an Escherichia coli model strain exposed to 10 adverse conditions (sodium chloride, ethanol, glycerol, hydrochloric and acetic acid, sodium hydroxide, heat (46[degrees]C), and cold (15[degrees]C), as well as ethidium bromide and the disinfectant benzalkonium chloride) were determined using DNA microarrays and Fourier ...

The objective of this study was to investigate tetracycline and ampicillin resistance in Escherichia coli isolated from the feces of 50 crossbred steers housed in 5 feedlot pens. The steers were not administered antibiotics over a 246-day feeding period. A total of 216 isolates were selected for further characterization. The ...

Leptospirosis is a widespread zoonotic disease caused by pathogenic leptospires. The identification of outer membrane proteins (OMPs) conserved among pathogenic leptospires, which are exposed on the leptospiral surface and expressed during mammalian infection, has become a major focus of leptospirosis research. pL40, a 40 kDa protein coded by the LA3744 ...

Classical swine fever virus (CSFV) is capable of counteracting innate cellular antiviral responses by inhibiting type I interferon (IFN)-[alpha]/[beta] induction. A function associated with CSFV [N.sup.pro], with respect to the inhibition of IFN-[beta] production, has been clearly elucidated. In this study, we explored the role of CSFV [E.sup.rns] in IFN-[beta] ...

Attachment of enveloped viruses to cells is triggered by the receptor-binding domain (RBD) on envelope glycoproteins (GP) binding to receptors located on the cell surface. To date, recognized receptors and RBD of hantaan virus (HTNV) have not been exactly defined. In this study, one monoclonal antibody (MAb) 3G1 possessing high ...

Bifidobacteria are common in the intestines of humans and other animals. Sorbitol-fermenting Bifidobacteria (SFB) are associated with human faecal pollution. The ratio of total Bifidobacteria (TB) to SFB has been proposed to be a means for determining the source (human or animal) of faecal pollution. In this study, SFB were ...

Campylobacter jejuni is one of the most common causes of gastroenteritis in the world. Given the potential risks to human, animal, and environmental health, the development and optimization of methods to quantify this important pathogen in environmental samples is essential. Two of the most commonly used methods for quantifying C. ...

A new species, Thozetella pinicola, was isolated from leaf litter of Pinus elliottu Engelm. in Hong Kong. This taxon is described and compared with existing species in the genus. It occurs on the substrate as creamy white sporodochia and has short black conidiophores. Morphological characters are typical of Thozetella and ...

Pleural effusion is a rare complication of atypical hepatitis A virus infection. It was proposed that immune complexes or local inflammation within the liver might be the cause of pleural effusion. In this case report, an 8 year-old girl with hepatitis A virus infection and unilateral pleural effusion was presented ...

Haemoptysis may be observed in one third of patients with pulmonary tuberculosis at any time during their disease. Tuberculosis may present with atypical radiological findings in patients with underlying diseases such as Diabetes Mellitus (DM). We presented a 58-year-old male with DM who haemorrhaged from the right bronchial artery although ...

We report a case of an 18 months old boy admitted for respiratory distress and wheezing who did not respond to nebulized salbutamol and budesonid. On chest X ray and computed tomographic investigation, a right paratracheal regular mass was seen. During hospitalization the clinical status of the child deteriorated. An ...

The purpose of this article is to bring up the efficacy of antimicrobials and the therapeutic problems that the antibiotic resistance imposes on clinicians for acute bacterial sinusitis (ABS), acute otitis media (AOM), and outpatient community acquired pneumonia (CAP) in adults in Turkey. The publications associated with respiratory pathogens on ...

Cigarette smoking is the primary cause of world-wide premature death. Therefore, thoracic physicians should try to inform patients of the harm smoking causes to airways and blood vessels. Unfortunately, in pursuing the goal of reducing the impact of chronic obstructive pulmonary disease, simple "global" guidelines were established to identify airway ...

Introduction: The mechanism of carcinogenesis of lung adenocarcinomas arising in smokers and non-smokers is distinct. Distinct tumorigenic mechanisms would imply differences in tumor biology, demographic characteristics, and survival. The aim of this study was to compare the patient characteristics and survival rates of current smokers and non-smokers with lung adenocarcinoma.
