There are several enteric bacterial diseases and conditions of pigs that require control to prevent overt disease, to reduce morbidity and mortality, and to improve the efficiency of production. Traditionally, veterinarians, feed manufacturers and producers have relied upon antibiotics and minerals (for example, ZnO, CuSO4) in diets for a large part of this control. However, recent trends, part...

Diagnosis: Intestinal spirochetosis. Results of histopathologic studies were pathognomonic for intestinal spirochetosis, a disorder that was first described in 1967 [1]. There are no distinct symptoms associated with intestinal spirochetosis other than diarrhea. The rate of colonization in humans is variable, but men who have sex with men and HIV-infected individuals appear to be at higher risk...

INTRODUCTION The genus Brachyspira contains well-known enteric pathogens of veterinary significance, suggested agents of colonic disease in humans, and one potentially zoonotic agent. There are recent studies showing that Brachyspira are more widespread in the wildlife community than previously thought. There are no records of this genus in wildlife from the southern Atlantic region and Antarct...

Reported herein is the complete genome sequence of the type strain B-78 (ATCC 27164) of Brachyspira hyodysenteriae, the etiological agent of swine dysentery. The 3.1-Mb genome consists of a 3.056-Mb chromosome and a 45-kb plasmid, with 2,617 protein-coding genes, 39 RNA genes, and 40 pseudogenes.

The prevalence of infection with intestinal spirochaetes in chickens in Western Australia was assessed by selective culture of faecal samples. Colonisation was common, with 35.1% of layer flocks and 53.3% of broiler breeder flocks being positive. Spirochaetes were recovered significantly more frequently from flocks with diarrhoea or reduced production than from clinically normal flocks. The gen...

An eleven month old filly was referred to the Research and Teaching Hospital of the Faculty of Veterinary Medicine at the University of Tehran. The animal presented a three-week history of diarrhea and previous treatments had failed to effect a recovery. Based on the history, clinical findings and results of laboratory investigations, it was assumed that a gastrointestinal disorder was affectin...

The sequence of 1383 nucleotides of the DNA encoding 16S rDNA was determined for strains of human intestinal spirochaetes, comprising an unnamed isolate and "Brachyspira aalborgi" NCTC 11492. A phylogenetic tree was inferred from aligned sequence comparisons between the intestinal spirochaetes, representatives of the Spirochaetales and Escherichia coli. The type strain of Brachyspira aalborgi, ...
