Anaerobic intestinal spirochaetes of the genus Brachyspira include several important pathogenic species, particularly those infecting pigs and chickens. In this study a multiplex-quantitative polymerase chain reaction (M-qPCR) assay was developed based on amplification of a 198 base pair portion of the NADH oxidase gene, using TaqMan probes for detecting and quantifying the three main pathogeni...
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...
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...
In vitro susceptibility of Brachyspira hyodysenteriae to organic acids and essential oil components.
The antibacterial potential of organic acids and essential oil components against Brachyspira hyodysenteriae, the causative pathogen of swine dysentery, was evaluated. Minimum inhibitory concentrations (MIC) of 15 compounds were determined at pH 7.2 and pH 6.0, using a broth microdilution assay. In addition, possible synergism was determined. MIC values for the three tested strains were similar...
The aim of the present study was to develop a reproducible porcine infection model with Brachyspira hyodysenteriae. The influence of different factors was evaluated, namely, age, a diet containing large quantities of soybean meal, housing and administration of cortisol or antacids. Furthermore, the synergistic effect of additional bacteria (Escherichia coli O141, Bacteroides vulgatus or a mixtu...
