| characterization of vaginal microbial communities in adult healthy women using cultivation-independent methods. | the normal microbial flora of the vagina plays an important role in preventing genital and urinary tract infections in women. thus an accurate understanding of the composition and ecology of the ecosystem is important to understanding the aetiology of these diseases. common wisdom is that lactobacilli dominate the normal vaginal microflora of post-pubertal women. however, this conclusion is based on methods that require cultivation of microbial populations; an approach that is known to yield a b ... | 2004 | 15289553 |
| identification and sequencing of bacterial rdnas in culture-negative amniotic fluid from women in premature labor. | our objective was to identify bacterial species present in culture-negative but 16s rdna-positive amniotic fluid samples from women in preterm labor. amniotic fluid from 69 women in preterm labor was cultured and examined for the proinflammatory cytokine interleukin-6 (il-6). polymerase chain reaction technology was used to detect highly conserved bacterial ribosomal dna sequences (16s rdnas). as previously reported, 16s rdnas were identified in 15 (94%) of 16 culture-positive amniotic fluid sam ... | 2004 | 15311367 |
| culture-independent analysis of vaginal microflora: the unrecognized association of atopobium vaginae with bacterial vaginosis. | although the pathogenesis of bacterial vaginosis remains elusive, a few microorganisms, such as gardnerella vaginalis, are considered markers on gram stain or culture. culture-independent analysis of vaginal microflora using 16s rdna cloning and sequencing of total bacterial communities reveals the gram-positive atopobium vaginae as a predominant species in disturbed vaginal flora. | 2004 | 15507931 |
| detection of novel organisms associated with salpingitis, by use of 16s rdna polymerase chain reaction. | although chlamydia trachomatis and neisseria gonorrhoeae are established causes of salpingitis, the majority of cases have no known etiology. we used broad-range 16s rdna polymerase chain reaction to identify novel, possibly uncultivable, bacteria associated with salpingitis and identified bacterial 16s sequences in fallopian-tube specimens from 11 (24%) of 45 consecutive women with laparoscopically confirmed acute salpingitis (the case patients) and from 0 of 44 women seeking tubal ligations (t ... | 2004 | 15551209 |
| peripartum bacteremias due to leptotrichia amnionii and sneathia sanguinegens, rare causes of fever during and after delivery. | we report three cases of delivery and postpartum bacteremia due to unusual anaerobic bacteria in healthy young women. leptotrichia amnionii bacteremia occurred during delivery in two mothers and was associated with fetal distress during labor. conversely, sneathia sanguinegens bacteremia occurred postpartum, 2 days after delivery, without consequence for the neonate. | 2004 | 15583348 |
| differences in the subgingival microbiota of swedish and usa subjects who were periodontally healthy or exhibited minimal periodontal disease. | previous studies have shown differences in the mean proportions of subgingival species in samples from periodontitis subjects in different countries, which may relate to differences in diet, genetics, disease susceptibility and manifestation. the purpose of the present investigation was to determine whether there were differences in the subgingival microbiotas of swedish and american subjects who exhibited periodontal health or minimal periodontal disease. | 2005 | 15642056 |
| molecular identification of an invasive gingival bacterial community. | a woman with neutropenia developed gingival hyperplasia. biopsy showed invasion of gingival tissue with mats of filamentous organisms, and molecular analysis by polymerase chain reaction and fluorescence in situ hybridization revealed capnocytophaga sputigena, leptotrichia species, and fusobacterium nucleatum. oral bacterial flora may cause invasive gingival disease with hyperplasia in immunocompromised patients. | 2005 | 15937752 |

| leptotrichia buccalis bacteremia in two patients with acute myelogenous leukemia. | leptotrichia buccalis is rarely implicated in systemic disease. we report two patients with clinically significant l. buccalis bacteremia which developed during the neutropenia secondary to chemotherapy. based upon our experience, l. buccalis bacteremia should be considered in certain high-risk immunocompromised patients with mucositis and/or gingivitis. | 2005 | 16701598 |
| leptotrichia buccalis: a rare cause of bacteraemia in non-neutropenic patients. | the anaerobic bacterium, leptotrichia buccalis (lb), belongs to the normal oral flora of humans and is seldom found in clinically significant specimens. however, on rare occasions, lb has been isolated from blood cultures from patients with lesions of the oral mucosa, in particular from patients with neutropenia. over a period of 6 months, lb was isolated from blood cultures in our laboratory from 2 immunocompetent patients. the identification characteristics of lb are described including the ty ... | 2006 | 16857623 |
| anaerobic bacteria cultured from the tongue dorsum of subjects with oral malodor. | the bacteria on the dorsum of the tongue are the most frequent cause of oral malodor; however, the bacterial flora of the tongue has not been well defined. although recent studies have used dna probes to detect the presence of certain periodontal pathogens, cultural studies have been limited because of the complexity of the flora of the tongue dorsum. the purpose of this study was to grow and to identify maximum numbers of capnophylic gram-negative bacilli and anaerobic micro-organisms by cultur ... | 2003 | 16887710 |
| [prevalence of leptotrichia amnionii sp. nov. in pregnant women]. | leptotrichia bacteria belong to the group of gram-negative anaerobes most frequently colonizing the oral cavity and reproductive organs. leptotrichia sanquigenes constitute one of the bacterial factors in postpartum bacteremia of mothers and newborns, whilst leptotrichia amnionii sp. nov., described for the first time in 2002, has turned out to be the etiopathogenetic factor in missed abortion in the second trimester of pregnancy. | 2006 | 17076202 |
| bacterial diversity in aortic aneurysms determined by 16s ribosomal rna gene analysis. | aortic aneurysms are common vascular conditions that cause considerable morbidity and mortality. understanding of the mechanisms involved in the pathogenesis of the condition remains limited. recently, infection has been suggested as possible contributor in the development of the disease. the aim of the present study was to examine aortic aneurysms for the presence of bacterial dna using polymerase chain reaction (pcr) targeting the 16s ribosomal rna (rrna) gene, followed by cloning and sequenci ... | 2006 | 17098542 |
| bacterial flora of the female genital tract: function and immune regulation. | the use of non-culture gene amplification techniques has improved our understanding of the composition of the vaginal bacterial ecosystem. in most healthy women in the reproductive period the predominant vaginal bacteria are one or more of the following species of lactobacillus: l. crispatus, l. iners and l. gasseri. however, in other apparently healthy women lactobacilli may be deficient or absent, being replaced by other lactic-acid-producing bacteria: atopobium, megasphaera and/or leptotrichi ... | 2007 | 17215167 |
| bacterial arthritis caused by leptotrichia amnionii. | leptotrichia amnionii is an organism that rarely causes female genital tract infection. we describe a case of a male patient with arthritis on the left knee joint due to this organism. | 2007 | 17392444 |
| leptotrichia amnionii found in septic abortion in denmark. | leptotrichia amnionii was first described in 2002 in the usa. only few cases have been reported to date, 3 in pregnant women and 2 in non-pregnant women. we present the first case of l. amnionii in scandinavia, found in a woman with spontaneous second trimester septic abortion. | 2007 | 17454911 |

| leptotrichia bacteremia in patients receiving high dose chemotherapy. | leptotrichia spp. are anaerobic, pencil shaped, gram-negative rods that are part of the normal oral and intestinal human flora. though not typically considered pathogenic, invasive leptotrichia infections have been reported in immunosuppressed patients. a perceived rise in the identification of leptotrichia spp. at our institution prompted a retrospective evaluation of this infection. laboratory and clinical records were reviewed to identify leptotrichia culture positive patients. over a 5 year ... | 2011 | 22205794 |
| metabolism of sugars by genetically diverse species of oral leptotrichia. | leptotrichia buccalis atcc 14201 is a gram-negative, anaerobic rod-shaped bacterium resident in oral biofilm at the tooth surface. the sequenced genome of this organism reveals three contiguous genes at loci: lebu_1525, lebu_1526 and lebu_1527. the translation products of these genes exhibit significant homology with phospho-α-glucosidase (pagl), a regulatory protein (gntr) and a phosphoenol pyruvate-dependent sugar transport protein (eiicb), respectively. in non-oral bacterial species, these ge ... | 2012 | 22230464 |
