Whether the association with gut microflora modifies the energy metabolism of chickens was investigated by varying the metabolizable energy consumption level from zero to above the maintenance requirement in the germ-free and conventional states. Single comb White Leghorn chicks were either fasted for 3 d (Expt l), or fed for 6 d at a fixed daily meal intake of 2, 5 or 8 g/d (Expt 2), or 5, 10 ...

Enteral tube feeding is common in both the hospital and community environment; however, patients can suffer alterations in faecal output that can have serious clinical sequelae. Problems associated with accurate characterisation of faecal output and definition of diarrhoea impede the comparison of research studies and prevent standardised assessment of therapeutic interventions in clinical prac...

background: campylobacteriosis is one of the most commonbacterial intestinal disorders of humans in many countries.a wide range of domestic and wild bird species have been identifiedas natural reservoirs. objectives: the aim of this studywas to determine the campylobacter spp from pet birds andscreen the determined campylobacters for presence of virulencecytolethal distending toxin (cdt) genes....

Background. The purpose of this study is to assess the effect of clindamycin (150 mg qid for 10 days) and ciprofloxacin (500 mg bd for 10 days) on the skin, nasal, saliva and intestinal microflora of healthy humans for a period of one year In addition, the consequences of the emergence and persistence of clindamycin and ciprofloxacin resistant bacteria in the normal microflora were studied. Met...

Paired caeca are situated at the junction of the small and large intestine and they normally contain a stable population of bacteria of very many different types [1, 6]. The flow rate is low in these regions which would allow for greater microbial multiplication in the lumen [18]. It is impossible to make detail microbial analysis of this heterogenous composite because the estimation of the mos...

Enteric microflora profiles vary considerably between active inflammatory bowel diseases (IBD) and healthy conditions. Intestinal microflora may partake in the pathogenesis of IBD by one or some ways: specific pathogenic infection induces abnormal intestinal mucosal inflammation; aberrant microflora components trigger the onset of IBD; abnormal host immune response loses normal immune tolerance...

The progressive public use of antimicrobial clothes has raised issues concerning skin health. A placebo-controlled side-to-side study was run with antimicrobial clothes versus fabrics of similar structure but minus the antimicrobial activity, to evaluate possible adverse effects on the healthy skin microflora. Sixty volunteers were enrolled. Each participant received a set of form-fitting T-shi...

The folding mechanism of typical proteins has been studied widely, while our understanding of the origin of the high stability of thermophilic proteins is still elusive. Of particular interest is how an atypical thermophilic protein with a novel fold maintains its structure and stability under extreme conditions. Folding-unfolding transitions of MTH1880, a thermophilic protein from Methanobacte...

Two representative thermophilic bacterial strains (T1 and T2) were isolated from a one-stage autothermal thermophilic aerobic digestion pilot-scale reactor. 16S rRNA gene analysis indicated that they were Hydrogenophilaceae and Xanthomonodaceae. These isolated strains were inoculated separately and/or jointly in sewage sludge, to investigate their effects on sludge stabilization under thermophi...
