Exposure to norepinephrine enhances Brachyspira pilosicoli growth, attraction to mucin and attachment to Caco-2 cells.
Brachyspira pilosicoli is an anaerobic intestinal spirochaete that colonizes the large intestine of a variety of species of birds and mammals, including human beings. Colonization may result in a mild colitis and diarrhoea in a condition known as 'intestinal spirochaetosis'. The catecholamine norepinephrine (NE), which is known to influence the behaviour of many bacterial species, may be presen...
متن کاملThe Intestinal Spirochete Brachyspira pilosicoli Attaches to Cultured Caco-2 Cells and Induces Pathological Changes
BACKGROUND Brachyspira pilosicoli is an anaerobic spirochete that has received relatively little study, partly due to its specialized culture requirements and slow growth. This bacterium colonizes the large intestine of various species, including humans; typically, a dense layer of spirochete cells may be found intimately attached by one cell end to the surface of colonic enterocytes. Colonized...

Failure to detect Brachyspira pilosicoli in bloodstream of Australian patients.
The isolation of intestinal spirochetes from the blood of a series of six French patients with a range of serious clinical problems was reported recently (3). These organisms and another from the blood of a patient with AIDS in the United States were subsequently identified as Brachyspira (Serpulina) pilosicoli (7). Intestinal carriage of B. pilosicoli occurs in Australia and is particularly co...
متن کاملiranian english learners’ perception and personality: a dual approach to investigating influential factors on willingness to communicate
abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
