| antibody-based detection and inhibition of vaginolysin, the gardnerella vaginalis cytolysin. | bacterial vaginosis (bv) is the most common vaginal infection worldwide and is associated with significant adverse sequelae. we have recently characterized vaginolysin (vly), the human-specific cytotoxin produced by gardnerella vaginalis and believed to play a critical role in the pathogenesis of bv and its associated morbidities. we hypothesize that novel antibody-based strategies may be useful for detection of vly and for inhibition of its toxic effects on human cells. using purified toxin as ... | 2009 | 19370149 |
| oleate lipase activity in gardnerella vaginalis and reconsideration of existing biotype schemes. | gardnerella vaginalis is a facultative gram positive organism that requires subculture every 1-2 days to maintain viability. it has been linked with bacterial vaginosis (bv), a syndrome that has been associated with increased risk for preterm delivery, pelvic inflammatory disease and hiv acquisition. about 10% of the g. vaginalis isolates have been reported to produce sialidase, but there have not been any studies relating sialidase production and biotype. sialidase activity is dramatically incr ... | 2009 | 19386125 |
| microflora of the penile skin-lined neovagina of transsexual women. | the microflora of the penile skin-lined neovagina in male-to-female transsexuals is a recently created microbial niche which thus far has been characterized only to a very limited extent. yet the knowledge of this microflora can be considered as essential to the follow-up of transsexual women. the primary objective of this study was to map the neo-vaginal microflora in a group of 50 transsexual women for whom a neovagina was constructed by means of the inverted penile skin flap technique. second ... | 2009 | 19457233 |
| comparison of oral and vaginal metronidazole for treatment of bacterial vaginosis in pregnancy: impact on fastidious bacteria. | bacterial vaginosis (bv) is a common condition that is associated with preterm birth and acquisition of complex communities of vaginal bacteria that include several fastidious species. treatment of bv in pregnancy has mixed effects on the risk of preterm delivery, which some hypothesize is due to variable antibiotic efficacy for the fastidious bacteria. both oral and intravaginal metronidazole can be used to treat bacterial vaginosis in pregnancy, but little is known about the impact of differen ... | 2009 | 19515236 |
| vertebral osteomyelitis and discitis due to gardnerella vaginalis. | gardnerella vaginalis is a facultative anaerobic gram-variable pleomorphic rod that forms part of the normal vaginal flora. it is most commonly associated with infection of the genital tract in women, but recognition of extravaginal g. vaginalis infection is becoming more frequent. we describe an unusual case of g. vaginalis vertebral osteomyelitis and discitis in a 38-year-old woman with no apparent predisposing factors. | 2009 | 19541786 |
| quantitative variations in the vaginal bacterial population associated with asymptomatic infections: a real-time polymerase chain reaction study. | the real-time polymerase chain reaction (pcr) quantification of several vaginal bacterial groups in healthy women and patients developing asymptomatic bacterial vaginosis (bv) and candidiasis (ca) was performed. statistical analysis revealed that the bv condition is characterised by a great variability among subjects and that it is associated with a significant increase of prevotella, atopobium, veillonella and gardnerella vaginalis, and a drop in lactobacillus. on the contrary, the vaginal micr ... | 2009 | 18762999 |

| utility of reflexive semen cultures for detecting bacterial infections in patients with infertility and leukocytospermia. | this study evaluated the benefit of reflexive semen cultures in peroxidase-positive samples drawn from 17,142 consecutive samples analyzed, in which 4.7% (807/17,142) had leukocytospermia and 12.7% of those (103/807) grew significant bacterial colonies on culture. considering the potential ramifications of the use of samples with bacteriospermia, we conclude that reflexive culture results are cost-effective and prudent. | 2009 | 18980764 |
| preterm labor and bacterial vaginosis-associated bacteria among urban women. | bacterial vaginosis (bv) affects millions of women, is extremely prevalent and is frequently chronic. we recognize numerous microbiologic variations among women with bv and this variability may explain the limited effectiveness of metronidazole in curing bv and/or reducing the risk of spontaneous preterm birth (sptb) among bv-positive pregnant women. we assessed the independent role of seven common bv-associated bacteria on the risk of spontaneous preterm birth (sptb) among urban pregnant women. | 2009 | 18999913 |
| gardnerella vaginalis acute hip arthritis in a renal transplant recipient. | we report the case of an acute hip septic arthritis caused by gardnerella vaginalis in a 48-year-old woman under immunosuppressive therapy for kidney transplantation. after surgical resection of the hip and 6 weeks of combination antibiotic therapy, a total hip prosthesis was successfully implanted with no recurrence after 4 years. | 2009 | 19020054 |
| lactocin 160, a bacteriocin produced by vaginal lactobacillus rhamnosus, targets cytoplasmic membranes of the vaginal pathogen, gardnerella vaginalis. | bacterial vaginosis (bv) is a commonly occurring vaginal infection that is associated with a variety of serious risks related to the reproductive health of women. conventional antibiotic treatment for this condition is frequently ineffective because the antibiotics tend to inhibit healthy vaginal microflora along with the pathogens. lactocin 160, a bacteriocin produced by healthy vaginal lactobacilli, is a promising alternative to antibiotics; this compound specifically inhibits the bv-associate ... | 2009 | 20445810 |
| evaluation of common organisms causing vaginal discharge. | vaginal discharge is very common problem among females. alteration in balance of normal vaginal organisms can cause the overgrowth of the bacteria that creates vaginal discharge. it is common among sexually active women yet there still remain gaps in our knowledge of this infectious disorder. | 2009 | 20524479 |
| bacterial vaginosis: an overview for 2009. | bacterial vaginosis has been appreciated as a unique clinical entity for well over 50 years. its essential manifestations are well established: a loss of the normal bacterial population of the vagina and their replacement by other species. investigations into this condition have led to a better understanding of its prevalence and epidemiology. microbiologic and biochemical studies have exposed the remarkably complex pathophysiologic events that occur with bacterial vaginosis. several major morbi ... | 2009 | 19399292 |
| bacterial vaginosis: a cause of infertility? | bacterial vaginosis (bv) is a common disorder of the genital tract in women characterized by an alteration of the normal acidic lactobacilli-predominant vaginal ecosystem to a vaginal environment dominated by gardnerella vaginalis, mycoplasma species and anaerobes, with an increase in ph. the present study evaluated whether bv is associated with reproductive complications in women. bv was screened with a gram stain of vaginal smear and interpretation was done using the nugent score. wet mount an ... | 2009 | 19833694 |
| natural antimicrobials and their role in vaginal health: a short review. | lactobacillus species maintain the vaginal ecosystem in a healthy condition by production of antimicrobial substances. depletion of lactobacilli in the vagina results in bacterial vaginosis (bv), where the normal flora is replaced by several bacterial pathogens, usually gardnerella vaginalis and obligate anaerobes. bv may cause complications such as premature labor, low birth weight and increased risk of hiv acquisition. the currently recommended antibiotic treatments for bv are not always effec ... | 2008 | 20657710 |
| what's the treatment for bacterial vaginosis? | a 28-weeks-pregnant patient complained of vaginal irritation and a malodorous white discharge that didn't improve after she used an over-the-counter cream indicated for yeast infections. what's a more effective treatment? | 2008 | 19033972 |
| importance of isolation and biotypization of gardnerella vaginalis in diagnosis of bacterial vaginosis. | the natural habitat of gardnerella vaginalis is a vagina since it could be located among 69% of women who have no signs of vaginal infection and in the vagina of as many as 13.5% girls. g. vaginalis is almost certainly identified among women diagnosed with bacterial vaginosis as well as in the urethra of their sexual partner. the increase in prevalence and concentration of g. vaginalis among patients diagnosed with this syndrome confirms that g. vaginalis plays a significant role in its pathogen ... | 2008 | 18816262 |

| [protease and phospholipase activities of candida albicans isolated from vaginal secretions with different ph values]. | even though vulvovaginal candidiasis and bacterial vaginosis are seldom simultaneously found, we have detected this association at an above average frequency. thus, we set out to study the activity of proteinases and phospholipases, virulence factors of candida albicans, to assess their role in the above mentioned association. of a total of 70 candida isolates were retrieved from samples of vaginal secretions analyzed at our diagnostic service, 65 were identified as c. albicans (a group of n=26 ... | 2008 | 18338921 |
| a retrospective analysis of isolates from patients with vaginitis in a private greek obstetric/gynecological hospital (2003-2006). | vaginitis is a common cause of complaints in women in various parts of the world. through our literature search, we identified noteworthy differences in the etiology of vaginitis based on the geographic location. this study was conducted to describe microbial etiology in a population of symptomatic women with vaginitis in greece. | 2008 | 18376352 |
| functional and phylogenetic characterization of vaginolysin, the human-specific cytolysin from gardnerella vaginalis. | pore-forming toxins are essential to the virulence of a wide variety of pathogenic bacteria. gardnerella vaginalis is a bacterial species associated with bacterial vaginosis (bv) and its significant adverse sequelae, including preterm birth and acquisition of human immunodeficiency virus. g. vaginalis makes a protein toxin that generates host immune responses and has been hypothesized to be involved in the pathogenesis of bv. we demonstrate that g. vaginalis produces a toxin (vaginolysin [vly]) ... | 2008 | 18390664 |
| the lower genital tract microbiota in relation to cytokine-, slpi- and endotoxin levels: application of checkerboard dna-dna hybridization (cdh). | in the present study the lower genital tract microbiota in asymptomatic fertile women (n=34) was identified and quantified by culturing vaginal secretions. also, vaginal and cervical samples were analyzed by a semiquantitative checkerboard dna-dna hybridization technique (cdh) based on genomic probes prepared from 13 bacterial species (bacteroides ureolyticus, escherichia coli, fusobacterium nucleatum, gardnerella vaginalis, mobiluncus curtisii ss curtisii, prevotella bivia, prevotella disiens, ... | 2008 | 18397461 |
| the polymicrobial hypothesis of bacterial vaginosis causation: a reassessment. | the cause of bacterial vaginosis remains controversial. the two leading hypotheses are that gardnerella vaginalis is the specific aetiologic agent versus the polymicrobial hypothesis that g. vaginalis acts in concert with other bacteria, principally anaerobes, to produce the disease. here we reassess the prevailing polymicrobial hypothesis, finding it conceptually problematical. no host initiating factors as postulated have been identified, nor is there conclusive evidence that g. vaginalis lack ... | 2008 | 18397551 |
| atopobium vaginae triggers an innate immune response in an in vitro model of bacterial vaginosis. | bacterial vaginosis is the most common vaginal disorder among women of reproductive age. the pathogenesis of bacterial vaginosis is poorly understood, but is defined by a transition in the vaginal flora from the predominant lactobacillus species to other bacterial species such as atopobium vaginae and gardnerella vaginalis. this change is associated with an increase in vaginal cytokine secretion. we hypothesize that vaginal epithelial cells respond to bacterial vaginosis-associated bacteria by t ... | 2008 | 18403235 |
| gardnerella vaginalis and lactobacillus sp in liquid-based cervical samples in healthy and disturbed vaginal flora using cultivation-independent methods. | our objective was to determine the morphotype of the adherent bacteria in liquid-based cytology (lbc) in smears with healthy and disturbed vaginal flora. and to use pcr technology on the same fixed cell sample to establish dna patterns of the 16s rna genes of the bacteria in the sample. thirty samples were randomly selected from a large group of cervical cell samples suspended in a commercial coagulant fixative "(boonfix)." pcr was used to amplify dna of five bacterial species: lactobacillus aci ... | 2008 | 18418885 |
| antibiotic resistance of gardnerella vaginalis in recurrent bacterial vaginosis. | fifty strains of gardnerella vaginalis isolated from 321 high vaginal swabs over a period of five months were tested for their antibiotic sensitivity. sixty eight per cent of all isolates were resistant to metronidazole while 76% were sensitive to clindamycin. all the strains isolated from cases with recurrence of infection were resistant to metronidazole. clindamycin therapy has a better clinical efficacy than metronidazole in cases of recurrent bacterial vaginosis. | 2008 | 18445953 |

| [the bacterial vaginosis--treatment problems]. | the changes in vaginal ecosystem (decreasing number of h2o2 producing lactobacillus spp. and increasing number of mobiluncus spp., gardnerella vaginalis, atopobium vaginae, prevotella spp., mycoplasma hominis, peptostreptococcus spp.) appears to be a major cause of bacterial vaginosis (bv). bacterial vaginosis is associated with infectious complications in pregnant and non-pregnant women and increasing risk of sti. the preventive role of natural vaginal microflora and problems of bv treatment ar ... | 2007 | 17607971 |
| alloscardovia omnicolens gen. nov., sp. nov., from human clinical samples. | the taxonomic position of 12 isolates tentatively assigned to the genus bifidobacterium on the basis of a limited phenotypic characterization was examined. the isolates were collected between 1978 and 2005 in belgium, sweden and norway, and originated from various human clinical samples, including urine, blood, urethra, oral cavity, tonsil, and abscesses of lung and aortic valve. on the basis of band number and clustering analysis, repetitive dna element-based pcr fingerprinting using the boxa1r ... | 2007 | 17625172 |
| probiotics for the treatment of women with bacterial vaginosis. | this review considers whether probiotics are effective agents for the treatment and/or prevention of bacterial vaginosis (bv). there seems to be an association between the absence of, or low concentrations of, vaginal lactobacilli and the development of bv. many studies have suggested that the presence of h2o2-producing vaginal lactobacilli may protect against bv, although some studies do not support this hypothesis. in-vitro studies have suggested that certain specific strains of lactobacilli a ... | 2007 | 17633390 |
| targeted pcr for detection of vaginal bacteria associated with bacterial vaginosis. | several novel bacterial species have been detected in subjects with bacterial vaginosis (bv) by using broad-range pcr assays, but this approach is insensitive for detecting minority species. we developed a series of taxon-directed 16s rrna gene pcr assays for more sensitive detection of key vaginal bacteria. we sought to determine the prevalence of each species in the vagina, its association with bv, and the utility of pcr for the microbiological diagnosis of bv. targeted pcr assays were develop ... | 2007 | 17687006 |
| effect of biofilm phenotype on resistance of gardnerella vaginalis to hydrogen peroxide and lactic acid. | bacterial vaginosis is the most common vaginal disorder worldwide. certain lactobacilli produce h2o2 and lactic acid, which normally suppress growth of anaerobes; however, in bacterial vaginosis, gardnerella vaginalis and other anaerobes proliferate, and the number of lactobacilli decreases. g. vaginalis colonizes the vaginal epithelium as a biofilm, which likely plays a role in colonization and relapsing infection. | 2007 | 17689638 |
| effect of lactobacillus challenge on gardnerella vaginalis biofilms. | bacterial vaginosis (bv) is the most common infectious condition in women. it is caused primarily by anaerobic bacteria which rapidly form biofilms recalcitrant to antibiotic treatment, elevate vaginal ph, induce inflammatory processes and displace indigenous lactobacilli from the vault. gardnerella vaginalis is commonly associated with these infections. microscopy analysis showed that within 72 h, viable g. vaginalis covered a surface area of 567 microm(2), reached a depth of 16 microm and a de ... | 2007 | 17234391 |
| an altered immunity hypothesis for the development of symptomatic bacterial vaginosis. | the hypothesis is advanced that the transition from a lactobacillus-dominated vaginal microflora to a microflora characteristic of bacterial vaginosis (bv), as well as development of the adverse consequences of bv in some women but not in others, are due to alterations in innate immunity. a microbial-induced inhibition of toll-like receptor expression and/or activity may block induction of proinflammatory immunity and lead to the proliferation of atypical vaginal bacteria. a lack of 70-kda heat- ... | 2007 | 17243059 |
