25. PCR Amplification from Fixed Tissue Indicates Frequent Involvement of Brachyspira aalborgi in Human Intestinal Spirochetosis
PCR procedures amplifying portions of the 16S rRNA and NADH oxidase genes of Brachyspira aalborgi and Serpulina pilosicoli were applied to DNA extracted from paraffin-embedded human colonic or rectal tissues from 30 Norwegian, Australian, and U.S. patients, 16 of whom had histologic evidence of intestinal spirochetosis (IS). B. aalborgi-specific sequences we

26. Detection by PCR and Isolation Assays of the Anaerobic Intestinal Spirochete Brachyspira aalborgi from the Feces of Captive Nonhuman Primates
The purpose of this study was to investigate the presence of the anaerobic intestinal spirochetes Brachyspira aalborgi and Brachyspira pilosicoli in the feces of captive nonhuman primates (n = 35) from 19 species housed at the Zoological Gardens, Perth, Western Australia. Both spirochete species are known to infect human beings. DNA was extracted from freshl

27. Characterization of a Periplasmic ATP-Binding Cassette Iron Import System of Brachyspira (Serpulina) hyodysenteriae
The nucleotide sequence of the pathogenic spirochete Brachyspira hyodysenteriae bit (for “Brachyspira iron transport”) genomic region has been determined. The bit region is likely to encode an iron ATP-binding cassette transport system with some homology to those encountered in gram-negative bacteria. Six open reading frames oriented in the same directio

28. Canine Intestinal Spirochetes Consist of Serpulina pilosicoli and a Newly Identified Group Provisionally Designated “Serpulina canis” sp. nov.†
The spirochetes inhabiting the large intestines of humans and animals consist of a diverse group of related organisms. Intestinal spirochetosis caused by Serpulina pilosicoli is a newly recognized enteric disease of human beings and animals with potential public health significance. The purpose of this study was to determine the species identity of canine in

29. Restriction fragment length polymorphism of the periplasmic flagellar flaA1 gene of Serpulina species.
Forty-one reference and field isolates of intestinal spirochetes representing Serpulina hyodysenteriae, Serpulina innocens, Serpulina pilosicoli, Brachyspira aalborgi, and nonclassified weakly beta-hemolytic intestinal spirochetes were compared by restriction fragment length polymorphism (RFLP) of the periplasmic flagellar (PF) flaA1 gene. Six genetically di

30. Cloning of a Beta-Hemolysin Gene of Brachyspira (Serpulina) hyodysenteriae and Its Expression in Escherichia coli
Brachyspira (Serpulina) hyodysenteriae induces a mucohemorrhagic diarrheal disease in pigs. The production of a beta-hemolysin has been considered a major virulence attribute of this organism. Previous reports have failed to correlate a specific cloned gene sequence with a purified beta-hemolytic protein sequence. Thus, questions still remain concerning the
