• Gram's stain results consistent with a diagnosis of bacterial vaginosis include (a) markedly reduced or absent Lactobacillus morphology, (b) predominance of Gardnerella morphotype, and (c) absent or few white blood cells. (theodora.com)
  • Generally, this condition is characterized by a shift in microbial composition from an abundance of lactobacilli in healthy women, to an increase of commensal anaerobic bacteria (such as Gardnerella , Atopobium , Prevotella and a panoply of other species). (news-medical.net)
  • Nugent scores that are based on weighted tallies of various cellular morphotypes (most notably lactobacilli, Gardnerella vaginalis , Bacteroides , as well as curved Gram-variable rod-shaped bacteria) are also widely used in the diagnosis of bacterial vaginosis. (news-medical.net)
  • These bacteria were often absent from gram stain smears of patients with other bacterial morphotypes. (cdc.gov)
  • Bacterial Vaginosis BV is a clinical syndrome resulting from replacement of the normal H2O2-producing Lactobacillus spp in the vagina with high concentrations of anaerobic bacteria (e.g. (cdc.gov)
  • When Gram stain is used, determining the relative concentration of the bacterial morphotypes characteristic of the altered flora of BV is an acceptable laboratory method for diagnosing BV. (cdc.gov)
  • It is dominated mainly by Lactobacillus species. (wikipedia.org)
  • We found that each genital condition was characterized by specific morphotypes in terms of microbial growth and colony colour, thus allowing the potential use of artificial intelligence not only to assess the presence of specific microbial genera/species but also to 'categorize' peculiar clinical conditions. (unibo.it)
  • The Mycobacterium bovis complex is a diverse group of species, serovars and morphotypes that cause tuberculosis-like diseases in animals and humans. (up.ac.za)
  • In this proof-of-concept study, we assessed the characteristics of digital plate images of vaginal swabs plated by WASPLab system into different media, in order to detect microbial growth morphotypes specific for each genital disorder. (unibo.it)
  • We first determined whether sensory neurons were present in rat colon by their responses to chemical mucosal stimulation and identified them in terms of physiological phenotype and soma morphotype. (nih.gov)
  • BV is defined by the disequilibrium in the vaginal microbiota, with decline in the number of lactobacilli. (wikipedia.org)
  • As the aforementioned loss of lactobacilli results in reduced lactic acid production, the pH in the vaginal lumen increases. (news-medical.net)
  • A total of 104 vaginal specimens were included: 62 cases of normal lactobacilli-dominated flora, 12 of BV, 16 of VVC, and 14 of AV were analysed. (unibo.it)
  • however, the rough morphotype changed to a nonfibrillar type with a smooth colony morphology after repeated subculturing in broth. (microbiologyresearch.org)
  • In the smooth morphotype these structures were not present. (microbiologyresearch.org)
  • Finally, the amount of Mobiluncus morphotypes present was quantitated. (cdc.gov)
  • Each morphotype was quantitated from 0 to 4+ with regard to the numbers of organisms present per oil immersion field as described in Table 1. (cdc.gov)
  • The relative amounts of each of the three classes of observed morphotypes was reported. (cdc.gov)
  • In xylene-water phase partition studies, the smooth morphotype was found to be hydrophobic, whereas the rough morphotype was found to be relatively hydrophilic. (microbiologyresearch.org)
  • The rough morphotype grew as equally white dry colonies which were hemolytic and had wrinkled edges. (microbiologyresearch.org)
  • In plaque samples from periodontitis patients we observed the presence of a rough morphotype of P. micros in addition to the previously recognized smooth morphotype. (microbiologyresearch.org)
  • Bacterial vaginosis is a condition resulting from replacement of the usual H 2 O 2 lactobacilli in the vagina with anaerobic bacteria such as Mobiluncus sp. (medscape.com)
  • The Nugent score is determined by estimating the relative concentration of bacterial morphotypes that occur in bacterial vaginosis. (medscape.com)
  • Grade 3/bacterial vaginosis: predominantly Gardnerella and/or Mobiluncus with few or absent lactobacilli. (medscape.com)
  • Within each of these groups, the investigators compared results for women with a healthy vaginal environment (dominated by Lactobacillus-morphotypes and free of bacterial vaginosis) to women who had a disturbed vaginal microbioata or an infection from bacteria, fungi or parasites. (news-medical.net)
  • Bacterial Vaginosis BV is a clinical syndrome resulting from replacement of the normal H2O2-producing Lactobacillus spp in the vagina with high concentrations of anaerobic bacteria (e.g. (cdc.gov)

  • When Gram stain is used, determining the relative concentration of the bacterial morphotypes characteristic of the altered flora of BV is an acceptable laboratory method for diagnosing BV. (cdc.gov)
  • Using sample post-contrasting with uranyl acetate and lead citrate, the authors described two morphotypes of bacteria differing in cytoplasmic protein density, which they argued was caused by oxidative stress. (frontiersin.org)
  • Emerged adults were discriminated into morphotypes according to the density of white scales on the first abdominal tergite. (preprints.org)
  • The treatment led to a significant increase in Lactobacilli in the operated mice, with a stronger effect noticed following submandibular gland removal. (frontiersin.org)
