PCR amplification from fixed tissue indicates frequent involvement of Brachyspira aalborgi in human intestinal spirochetosis. (1/91)

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 were identified by PCR in 10 of the IS patients (62.5%) but none of the others, while S. pilosicoli sequences were not detected in tissues from any patient. Direct sequencing of products from three of the positive samples provided further confirmation of the presence of B. aalborgi. B. aalborgi may be a more common cause of intestinal spirochetosis than has been previously thought.  (+info)

Lipo-oligosaccharide profiles of Serpulina pilosicoli strains and their serological cross-reactivities. (2/91)

The purpose of this study was to determine the presence of lipopolysaccharide-like material in the intestinal spirochaete Serpulina pilosicoli and the extent of antigenic cross-reactivity of this material in different strains of the species. Hot water-phenol, aqueous-phase extracts from five porcine and three human strains of S. pilosicoli, and from seven strains of four other Serpulina spp., were separated by SDS-PAGE and silver-stained profiles were obtained. All S. pilosicoli strains had a predominant band at c. 16 kDa. Some also had a partial ladder-like profile, consistent with the presence of semi-rough lipo-oligosaccharide (LOS); this was more obvious in Western immunoblot analysis. LOS from each S. pilosicoli strain was serologically distinct in immunoblot analysis and there was no cross-reactivity with other Serpulina spp. The serological diversity found amongst the LOS of S. pilosicoli strains may help to explain why individual people and animals can suffer repeated infections with different strains of the organism.  (+info)

Scanning electron microscopy and fluorescent in situ hybridization of experimental Brachyspira (Serpulina) pilosicoli infection in growing pigs. (3/91)

Two groups of six 8-week-old pigs were challenged with 1x10(9) cfu Brachyspira (Serpulina) pilosicoli or Serpulina intermedia daily for 3 consecutive days to study the pathology of porcine colonic spirochetosis by scanning electron microscopy (SEM) and fluorescent in situ hybridization (FISH) with oligonucleotide probes targeting ribosomal RNA specific for B. pilosicoli and the genus Brachyspira/Serpulina. Six pigs served as noninoculated controls. The animals were euthanatized successively between postinoculation days 14 and 24. B. pilosicoli was reisolated in feces from all of the inoculated pigs; however, only two pigs developed transient watery diarrhea. S. intermedia was reisolated from four of the inoculated pigs, but clinical signs were not observed. Gross examination of the B. pilosicoli-infected pigs revealed dilated large intestines with a hyperemic mucosa, whereas the large intestines of the S. intermedia-inoculated pigs and the control pigs appeared normal. SEM examination of B. pilosicoli-infected pigs revealed degenerated epithelial cells and spirochetal colonization of the colonic mucosa in four pigs. By FISH, B. pilosicoli cells were found colonizing and invading the surface epithelium and the crypts in all the pigs. Spirochetal crypt colonization markedly exceeded the occurrence of spirochetes on the mucosal surface. SEM examination of S. intermedia-inoculated pigs revealed no abnormalities, and Serpulina cells were detected only sporadically in the otherwise normal-appearing mucosa of four pigs by FISH. The results provide further evidence that B. pilosicoli is associated with colitis in pigs, although the gross lesions are mild. The spirochete is capable of colonizing the large intestine, inducing mucosal damage, invasion of the crypt and surface epithelium, and focal infiltration of the lamina propria. In addition, the study shows the applicability of FISH for specific identification of B. pilosicoli in formalin-fixed tissue.  (+info)

Cloning and DNA sequence analysis of an immunogenic glucose-galactose MglB lipoprotein homologue from Brachyspira pilosicoli, the agent of colonic spirochetosis. (4/91)

Colonic spirochetosis (CS) is a newly emerging infectious disease of humans and animals caused by the pathogenic spirochete Brachyspira (formerly Serpulina) pilosicoli. The purpose of this study was to characterize an antigen that was recognized by antibodies present in sera of challenge-exposed pigs. The gene encoding the antigen was identified by screening a plasmid library of human B. pilosicoli strain SP16 (ATCC 49776) genomic DNA with hyperimmune and convalescent swine sera. The predicted amino acid sequence encoded by the cloned B. pilosicoli gene had a high degree of similarity and identity to glucose-galactose MglB lipoprotein. Located 106 bp downstream of the putative mglB gene was a 3'-truncated open reading frame with 73.8% similarity and 66.3% identity to mglA of Escherichia coli, suggesting a gene arrangement within an operon which is similar to those of other bacteria. A single copy of the gene was present in B. pilosicoli, and homologous sequences were widely conserved among porcine intestinal spirochetes Serpulina intermedia, Brachyspira innocens, Brachyspira murdochii, and the avian Brachyspira alvinipulli, but not in porcine Brachyspira hyodysenteriae, human Brachyspira aalborgi, and porcine Treponema succinifaciens. The deduced molecular weight of the mature MglB lipoprotein was consistent with expression by the cloned gene of a polypeptide with an apparent molecular weight of 36,000, as determined by Western blot analysis and [(3)H]palmitate labeling. Because mucin is the principal constituent of the colonic mucus gel and consists of glycoproteins that can serve as the substrate for growth and chemotaxis of B. pilosicoli in vitro, a role for MglB in mucosal localization of the spirochete appears consistent with the pathogenesis of CS. However, the presence of homologous sequences in closely related but nonpathogenic commensal spirochetes suggests that other virulence determinants may be required for pathogenesis.  (+info)

Evaluation of blood culture systems for detection of the intestinal spirochaete Brachyspira (Serpulina) pilosicoli in human blood. (5/91)

The anaerobic intestinal spirochaete Brachyspira (Serpulina) pilosicoli has been isolated from the bloodstream of French patients by manual blood culture systems. The purpose of this study was to determine whether the automated and manual blood culture systems used in Australia are suitable for growth and detection of this organism. Strains of B. pilosicoli were added to human blood to give concentrations ranging from 1 x 10(4) to 1 x 10(1) spirochaetes/ml and 10-ml volumes were inoculated into the media. Three strains of B. pilosicoli grew slowly in all manual Hemoline and BBL Septi-Chek formulations tested. Subcultures taken between 2 and 10 days after inoculation yielded growth only after incubation for a further 5-8 days. Growth and automated detection were achieved in the BACTEC system with Anaerobic/F medium with or without Fastidious Organism Supplement. Minimum time to signal for nine strains varied between 5.6 and 14.9 days, with a minimum concentration of 10(1) spirochaetes/ml of blood being detected. None of nine strains gave a positive signal in the BacT/Alert system when FAN Anaerobic culture bottles were used; however, four strains were detected by subculture taken at 7 or 14 days after inoculation. When Anaerobic medium was used in the BacT/Alert system, two of three strains gave a signal and the other strain grew and was detected by subculture. Spirochaetaemias caused by B. pilosicoli may be unrecognised because detection time by the signal or subculture exceeds 5 days.  (+info)

Comparative prevalences of Brachyspira aalborgi and Brachyspira (Serpulina) pilosicoli as etiologic agents of histologically identified intestinal spirochetosis in Australia. (6/91)

DNA from gastrointestinal biopsy specimens from 28 Australian patients with histologic evidence of intestinal spirochetosis (IS) was subjected to PCRs to amplify segments of the 16S rRNA and NADH oxidase genes of Brachyspira aalborgi and Brachyspira (Serpulina) pilosicoli. B. aalborgi was identified in specimens from 24 (85.7%) patients and B. pilosicoli in those from 4 (14.3%) patients (2 of whom were also positive for B. aalborgi). For two patients, no product was amplified. This study demonstrates that B. aalborgi is much more commonly involved in histologically identified IS in Australian patients than is B. pilosicoli. This is the first report of amplification of B. pilosicoli DNA from humans with IS.  (+info)

Diagnostic examination of human intestinal spirochetosis by fluorescent in situ hybridization for Brachyspira aalborgi, Brachyspira pilosicoli, and other species of the genus Brachyspira (Serpulina). (7/91)

Human intestinal spirochetosis, characterized by end-on attachment of densely packed spirochetes to the epithelial surface of the large intestines as a fringe has been associated with the weakly beta-hemolytic spirochetes Brachyspira aalborgi and Brachyspira (Serpulina) pilosicoli. In this study, fluorescent in situ hybridization with oligonucleotide probes targeting 16S or 23S rRNA of B. aalborgi, B. pilosicoli, and the genus Brachyspira was applied to 40 sections of formalin-fixed, paraffin-embedded intestinal biopsy specimens from 23 Danish and 15 Norwegian patients with histologic evidence of intestinal spirochetosis. Five biopsy specimens from patients without intestinal spirochetosis and three samples from pigs with experimental B. pilosicoli colitis were examined as well. In addition, the 16S ribosomal DNAs of two clinical isolates of B. aalborgi were sequenced, and a PCR procedure was developed for the identification of B. aalborgi in cultures. The genotypic characteristics of the two clinical isolates showed very high (99.5%) similarity with two existing isolates, the type strain of B. aalborgi and a Swedish isolate. Hybridization with the Brachyspira genus-specific probe revealed a brightly fluorescing fringe of spirochetes on the epithelia of 39 biopsy specimens, whereas 1 biopsy specimen was hybridization negative. The spirochetes in biopsy specimens from 13 Danish and 8 Norwegian patients (55.3%) were identified as B. aalborgi. The spirochetes in the biopsy specimens from the other 17 patients hybridized only with the Brachyspira probe, possibly demonstrating the involvement of as-yet-uncharacterized Brachyspira spirochetes in human intestinal spirochetosis.  (+info)

Antimicrobial susceptibility testing of porcine Brachyspira (Serpulina) species isolates. (8/91)

No standardized method for susceptibility testing of Brachyspira spp. is currently available. A broth dilution procedure was evaluated and used to test the activities of six antimicrobial agents for 108 isolates of Swedish porcine Brachyspira spp. representing biochemical groups I, II, and III. Group I corresponds to Brachyspira hyodysenteriae, group II corresponds to B. intermedia, and group III corresponds to B. murdochii and B. innocens. A panel was designed with the antimicrobial agents dried in tissue culture trays with wells that allowed a liquid volume of 0.5 ml in each and agitation of the broth when incubated on a shaker. The MICs were determined by using brain heart infusion broth with 10% fetal calf serum. For 10 isolates, the results obtained in broth were compared to the MICs obtained on two different types of agar. Different inoculum densities and incubation times were also compared. The concentrations at which 90% of the B. hyodysenteriae isolates (n = 72) were inhibited in the broth dilution test by tiamulin (0.25 micro g/ml), tylosin (>256 micro g/ml), erythromycin (>256 micro g/ml), clindamycin (>4 micro g/ml), virginiamycin (4 micro g/ml), and carbadox (0.06 micro g/ml) were determined. The MICs tended to be lower in broth than on agar. Differences in inoculum densities and incubation times had little influence on the MICs. The evaluated broth dilution test was simple to perform, the end points were easily read, and the results were reproducible and reliable. No isolates with decreased susceptibility to tiamulin were found among the Swedish isolates tested.  (+info)

Porcine intestinal spirochaetes are fastidious anaerobic organisms and, as a consequence, it has been necessary to develop various protocols to enhance their isolation from or detection in faeces. Immunomagnetic separation (IMS) is a method developed recently to improve separation of target cells from mixed cell suspensions. The purpose of the present study was to compare the relative sensitivity of IMS for isolation of Brachyspira pilosicoli and Brachyspira hyodysenteriae with current routine diagnostic methods (culture on selective media and PCR) for detection of these micro-organisms in pig faeces. Neither direct nor indirect IMS methods enhanced the sensitivity of detection of either organism when performed with the recommended washings during sample processing. Performance of the IMS procedure without washing gave sensitivity at levels similar to direct culture onto selective medium. Further development of IMS techniques is required to improve isolation rates of Brachyspira species from faecal
Strain 56-150T (= DSM 12563 = ATCC 51284 = CIP 105832) is the type strain of the species Brachyspira murdochii. This strain was first described as Serpulina murdochii [1,2], and later transferred to the genus Brachyspira [3]. The genus Brachyspira currently consists of seven species, with Brachyspira aalborgi as the type species [4,5]. The genus Brachyspira is the only genus in the not yet formally described family Brachyspiraceae [6,7]. The generic name derives from brachys, Greek for short, and spira, Latin for a coil, a helix, to mean a short helix [5]. The species name for B. murdochii derives from the city of Murdoch, in recognition of work conducted at Murdoch University in Western Australia, where the type strain was identified [1]. Some species of the genus Brachyspira cause swine dysentery and porcine intestinal spirochetosis. Swine dysentery is a severe, mucohemorrhagic disease that sometimes leads to death of the animals [1]. B. murdochii is generally not considered to be a ...
The anaerobic intestinal spirochaete Brachyspira pilosicoli colonizes the large intestine of various species, including humans. In the colon this spirochaete can penetrate the overlying mucus layer, attach by one cell end to the underlying enterocytes, and initiate localized colitis and diarrhoea. The aim of this study was to investigate whether, as part of the colonization process, B. pilosicoli is attracted to mucin. Fifteen B. pilosicoli strains isolated from humans, pigs, chickens and dogs, and a control strain of Brachyspira hyodysenteriae, were analysed for their ability to enter solutions of hog gastric mucin in an in vitro capillary tube assay. No significant attraction was detected with 1 % mucin, but some strains started to enter a 2 % solution, and attraction then increased with increasing concentrations to peak at around 6-8 % mucin. A similar increase was seen with B. hyodysenteriae, although this activity peaked at 6 % mucin and then declined, suggesting that the two species have different
Brachyspira species have been implicated as a potential cause of gastroenteritis in humans; this is, however, controversial. In 733 gastroenteritis cases and 464 controls, we found 29 samples positive for Brachyspira species (2.3% of cases and 2.6% of controls; P = 0.77). Brachyspira species were not associated with gastroenteritis in ... read more humans. show less ...
Serpulina pilosicoli is an anaerobic spirochete which has been isolated from the colons of pigs with enteric disease. The clinical and pathologic features of experimental infections of conventional pigs (born by normal farrowing with a naturally acquired intestinal flora) with three strains of S. pilosicoli were determined in order to confirm the enteropathogenicity of this species. Strains were derived from the colons of British pigs with colitis and passaged 8 to 10 times during expansion and purification in vitro. Eighteen ten-week-old Large White-Landrace cross pigs were each inoculated once orally with 0.7 x 10(9) to 1.6 x 10(9) of one of three strains of S. pilosicoli. Six pigs were challenged with each strain. Control pigs were dosed with uninfected broth medium or with 1.8 x 10(7) cells of the nonpathogenic Serpulina innocens. Eight pigs (two to four per S. pilosicoli challenge group) developed soft or diarrheic feces (fecal dry matter | 24%) between 3 and 8 days after challenge, which persisted
The increased incidence of IBS after a gastroenteritis episode suggests microbial perturbation as an underlying factor.1 However, studies of faecal microbiota in IBS have not demonstrated reproducible alterations.2 In this investigation, potentially pathogenic Brachyspira species were identified in the colonic mucosa of 31% of patients with IBS but not in any healthy individual. Brachyspira attachment to the epithelial brush border was observed in every fifth patient with IBS and associated with diarrhoea, accelerated oro-anal transit, mild mucosal inflammation and mast cell activation. Hence, Brachyspira colonisation defines a sizeable and distinctive subgroup of patients with IBS that might be responsive to antibiotic therapy. However, metronidazole treatment paradoxically resulted in spirochaete invasion into crypts and goblet cells. Thus, our observations suggest a role for Brachyspira in IBS-D pathogenesis but also urge caution with regard to antibiotic therapy in IBS.. While Brachyspira ...

The term intestinal spirochetosis (IS) was coined in 1967 for an infection of the large bowel in which uncharacterized spirochetes were found attached by one end to the colonic epithelium to form a dense false brush border (11). Subsequently, there has been considerable controversy over the pathologic and epidemiologic significance of this colonization. Some investigators have reported symptoms such as rectal bleeding and/or diarrhea in patients with IS (6, 7, 9, 20, 30, 42), and in some cases clinical improvement has occurred after treatment with antibiotics which eliminated the spirochetes (7, 14, 29). Other investigators have been unable to relate the presence of intestinal spirochetes to gastrointestinal symptoms (3, 26, 31, 32).. Most studies of IS have involved histologic examination of biopsy material, without concurrent bacterial culture (17, 21, 24, 31, 42); a smaller number of studies have involved only fecal culture for spirochetes (3, 13, 18, 30, 33). One exception was a study by ...
For swine dysentery, which is caused by Brachyspira hyodysenteriae infection and is an economically important disease in intensive pig production systems worldwide, a perfect or error-free diagnostic test (gold standard) is not available. In the absence of a gold standard, Bayesian latent class modelling is a well-established methodology for robust diagnostic test evaluation. In contrast to risk factor studies in food animals, where adjustment for within group correlations is both usual and required for good statistical practice, diagnostic test evaluation studies rarely take such clustering aspects into account, which can result in misleading results. The aim of the present study was to estimate test accuracies of a PCR originally designed for use as a confirmatory test, displaying a high diagnostic specificity, and cultural examination for B. hyodysenteriae. This estimation was conducted based on results of 239 samples from 103 herds originating from routine diagnostic sampling. Using ...

A fluorescent-labelledin situ hybridization method targeting rRNA was devised to facilitate specific identification and diagnosis of diarrhoea and colitis in pigs caused by the genus Serpulina, as well as to distinguish the species Serpulina hyodysenteriae and Serpulina pilosicoli in formalin-fixed colon tissue sections. A genus-specific oligonucleotide probe SER1410 targeting the five species of porcine Serpulina was thus designed. Furthermore, species specific oligonucleotide probes (Hyo1210, Pilosi209 and Pilosi1405) were also designed to detect, identify and differentiate S. hyodysenteriae and S. pilosicoli. These probes clearly demonstrated and possessed the desired specificity, when evaluated by whole cell hybridization on five reference strains and 20 isolates covering the five species of porcine Serpulina. Furthermore, the oligonucleotide probes were specific when used both, for the detection of Serpulina isolates at genus level as well as for specific detection of S. hyodysenteriae and ...

This chapter consists of short notes, diagrams, and tables to summarize infections caused by spirochaetes. The chapter begins with a classification system to divide these organisms into Treponema, Borrelia, Leptospira, and Brachyspira. Separate sections then follow on the infections of most clinical significance for the tropics and subtropics, including leptospirosis, syphilis, non-venereal treponemes, and relapsing fevers. For ease of reference, each topic is broken down into sections, including classification, epidemiology, microbiology, pathophysiology, clinical syndromes, diagnosis, treatment and prevention.

Methane is metabolized principally by methanotrophs and methanogens in the global carbon cycle. Methanotrophs consume methane as the only source of carbon, while methanogens produce methane as a metabolic byproduct. Methylotrophs, which are microorganisms that can obtain energy for growth by oxidizing one-carbon compounds, such as methanol and methane, are situated between methanotrophs and methanogens. Methanogens can obtain energy for growth by converting a limited number of substrates to methane under anaerobic conditions. Three types of methanogenic pathways are known: CO2 to methane [MD:M00567], methanol to methane [MD:M00356], and acetate to methane [MD:M00357]. Methanogens use 2-mercaptoethanesulfonate (CoM; coenzyme M) as the terminal methyl carrier in methanogenesis and have four enzymes for CoM biosynthesis [MD:M00358]. Coenzyme B-Coenzyme M heterodisulfide reductase (Hdr), requiring for the final reaction steps of methanogenic pathway, is divided into two types: cytoplasmic HdrABC in ...
Swine dysentery (SD) is an economically important diarrheal disease in pigs caused by different strongly hemolytic Brachyspira (B.) species, such as B. hyodysenteriae, B. suanatina and B. hampsonii. Possible associations of epidemiologic data, such as multilocus sequence types (STs) to virulence gene profiles and antimicrobial susceptibility are rather scarce, particularly for B. hyodysenteriae isolates from Germany. In this study, B. hyodysenteriae (n = 116) isolated from diarrheic pigs between 1990 and 2016 in Germany were investigated for their STs, susceptibility to the major drugs used for treatment of SD (tiamulin and valnemulin) and genes that were previously linked with virulence and encode for hemolysins (tlyA, tlyB, tlyC, hlyA, BHWA1_RS02885, BHWA1_RS09085, BHWA1_RS04705, and BHWA1_RS02195), outer membrane proteins (OMPs) (bhlp16, bhlp17 ...
General Information: Brachyspira hyodysenteriae is the causative agent of swine dysentery, which is a severe mucohemorrhagic diarrheal disease of pigs that has economic significance for pork-producing countries. The bacterium can survive for several weeks in cold moist conditions but not under warm dry conditions. It spreads slowly, building up in numbers as the dose rate of the causal agent builds up in the environment. Pigs that recover develop a low immunity and rarely suffer from the disease again. It can be spread by other organisms (flies, mice, birds and dogs) or external mechanical factors; its main habitat is the porcine cecum and colon. It is chemotactically attracted to mucin which it penetrates with a corkscrew-like motility. ...

Multilocus enzyme electrophoresis was used to determine genetic relationships amongst 32 intestinal spirochaetes (Serpulina spp.) isolated from rats (17), rheas (7), chickens, (4), ducks (2), a swan (1) and a flamingo (1). The strains were divided into 20 electrophoretic types (ETs), with a mean genetic diversity per locus of 0.62. The results were compared with those previously published for porcine intestinal spirochaetes. One strain from a healthy rat, and three rhea strains which were recovered from cases of necrotizing typhlitis, were grouped in the same ETs as certain porcine strains of Serpulina hyodysenteriae. The rhea strains could be differentiated from these by pulsed-field gel electrophoresis. Fifteen of the rat strains were genetically and phenotypically closely related. In contrast the avian strains were genetically more heterogeneous, with pathogenic isolates located in three different genetic groups.. ...

This report describes postweaning diarrhea in a group of nursery pigs in which Lawsonia intracellularis, Brachyspira pilosicoli, and several strains of enterotoxigenic Escherichia coli were identified. Affected pigs were anorexic and gaunt, and feces were light brown, loose to watery, and contained pieces of feed and mucus. Associated risk factors that may have played a role in occurrence of diarrhea include diet, pig movement, sanitation, environment, and rodent control. Clinical management strategies that were instituted addressed some of these risk factors. Keywords: nursery pigs, diarrhea, multiple pathogens. ...

Losses associated with gastric ulceration might warrant an ongoing monitoring program.The first step of a monitoring program is to ensure that the herdsmen are familiar with the clinical signs of gastric ulceration. Blood loss into the gastrointestinal tract, the main clinical event in this condition, may cause anemia and melena. Anemia may be severe, resulting in a very pale, weak pig with rapid breathing. The feces are generally scant, black, and tarry. A number of infectious agents (eg, Lawsonia intracellularis, Salmonella serovars, and Brachyspira hyodysenteriae) may induce lesions resulting in blood loss into the intestines, but these conditions are associated with diarrhea, which is not the case with gastric ulcers. Pigs with extensive and severe erosive lesions of the pars oesophagea may continue to appear healthy if blood loss is minimal. Damaged tissue heals rapidly. If the opening of the oesophagus into the stomach is restricted because of scar tissue formation, pigs may be observed to ...
