  • BD™ Gardnerella Selective Agar with 5% Human Blood
    INSTRUCTIONS FOR USE – READY-TO-USE PLATED MEDIA PA-254094.06 Rev.: July 2014 BD Gardnerella Selective Agar with 5% Human Blood INTENDED USE BD Gardnerella Selective Agar with 5% Human Blood is a partially selective and differential medium for the isolation of Gardnerella vaginalis from clinical specimens. PRINCIPLES AND EXPLANATION OF THE PROCEDURE Microbiological method. Gardnerella vaginalis is considered to be one of the organisms causing vaginitis.1-4 Although the organism may be present in a high percentage of normal women in the vaginal flora, its importance as a cause of non-specific vaginitis (also called bacterial vaginosis) has never been questioned. In symptomatic women, G. vaginalis frequently is associated with anaerobes such as Prevotella bivia, P. disiens, Mobiluncus, Peptostreptococcus, and/or others which are a regular part of the urethral or intestinal, but not vaginal flora. In non-specific vaginitis, normal Lactobacillus flora is reduced or absent. Gardnerella vaginalis is considered to be the indicator organism for non-specific vaginitis which, in fact, is a polymicrobial infection.3,4 Although non- culture methods such as a direct Gram stain have been recommended in recent years for genital specimens, culture is still preferred by many laboratories.1,5 G. vaginalis may also be responsible for a variety of other diseases such as preterm birth, chorioamnionitis, urinary tract infections, newborn infections, and septicemia.6 The detection of the organism on routinely used media is difficult since Gardnerella and other

Abstract: The human body is host to a large number of microorganisms which conform the human microbiota, that is known to play an important role in health and disease. Although most of the microorganisms that coexist with us are located in the gut, microbial cells present in other locations (like skin, respiratory tract, genitourinary tract, and the vaginal zone in women) also play a significant role regulating host health. The fact that there are different kinds of microbiota in different body areas does not mean they are independent. It is plausible that connection exist, and different studies have shown that the microbiota present in different zones of the human body has the capability of communicating through secondary metabolites. In this sense, dysbiosis in one body compartment Citation: Martínez, J.E.; Vargas, A.; may negatively affect distal areas and contribute to the development of diseases.

Department of Neurosurgery, Essex Neurosciences Centre, Queens Hospital, Romford, RM7 0AG, UK 2. Department of Microbiology, Queens Hospital, Romford, RM7 0AG, UK Corresponding author: Sebastian M Toescu, Department of Neurosurgery, Essex Neurosciences Centre, Queens Hospital, Romford, RM7 0AG, UK, [email protected] Abstract: A 49 year old female underwent multiple craniotomies for resection of aggressive meningeal tumours (WHO Grade III). She re-presented to hospital with sepsis due to ventriculitis. The craniotomy wound was urgently debrided and isolates of the Gram negative rod Weeksella virosa identified on 16S PCR. This species is most commonly found as a genitourinary commensal and here we report the first documented case of intracranial infection with this species and its successful treatment with a 6-week course of oral -lactam antibiotics. Keywords: Weeksella virosa; central nervous system infection; ventriculitis; anaplastic meningioma 1 Clinical details A 49-year old, right handed female presented with early morning headaches and vomiting. Her past medical history was unremarkable. On examination, the only focal deficit elicited was a dense left homonymous hemianopia. Magnetic resonance imaging (MRI) of the brain revealed a lesion occupying the trigone and occipital horn of the right lateral ventricle (Figure 1A). No other intracranial lesions were seen, and computed tomography scans of the chest, abdomen and pelvis did not show any abnormalities. A complete macroscopic excision of the tumour was effected without problems. The postoperative MRI scan did not show any residual enhancing tumour tissue.

  • Bacterial Diversity and Functional Analysis of Severe Early Childhood
    www.nature.com/scientificreports OPEN Bacterial diversity and functional analysis of severe early childhood caries and recurrence in India Balakrishnan Kalpana1,3, Puniethaa Prabhu3, Ashaq Hussain Bhat3, Arunsaikiran Senthilkumar3, Raj Pranap Arun1, Sharath Asokan4, Sachin S. Gunthe2 & Rama S. Verma1,5* Dental caries is the most prevalent oral disease afecting nearly 70% of children in India and elsewhere. Micro-ecological niche based acidifcation due to dysbiosis in oral microbiome are crucial for caries onset and progression. Here we report the tooth bacteriome diversity compared in Indian children with caries free (CF), severe early childhood caries (SC) and recurrent caries (RC). High quality V3–V4 amplicon sequencing revealed that SC exhibited high bacterial diversity with unique combination and interrelationship. Gracillibacteria_GN02 and TM7 were unique in CF and SC respectively, while Bacteroidetes, Fusobacteria were signifcantly high in RC. Interestingly, we found Streptococcus oralis subsp. tigurinus clade 071 in all groups with signifcant abundance in SC and RC. Positive correlation between low and high abundant bacteria as well as with TCS, PTS and ABC transporters were seen from co-occurrence network analysis. This could lead to persistence of SC niche resulting in RC. Comparative in vitro assessment of bioflm formation showed that the standard culture of S. oralis and its phylogenetically similar clinical isolates showed profound bioflm formation and augmented the growth and enhanced bioflm formation in S. mutans in both dual and multispecies cultures. Interaction among more than 700 species of microbiota under diferent micro-ecological niches of the human oral cavity1,2 acts as a primary defense against various pathogens. Tis has been observed to play a signifcant role in child’s oral and general health.

    Inuence of Host Plants on the Diversity of Gut Microbiota Communities of Fall Armyworm Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) Juliana Amaka Ugwu ( [email protected] ) Forestry Research Institute of Nigeria https://orcid.org/0000-0003-1862-6864 Fred Asiegbu Department of Forest sciences, University of Helsinki, P.O Box 27, FIN-00014 Helsinki, Finland. Research Article Keywords: host plants, microbial variability, fall armyworm, larvae, bacteria Posted Date: June 30th, 2021 DOI: https://doi.org/10.21203/rs.3.rs-657579/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/19 Abstract The gut bacteria of insects inuence their host physiology positively, although their mechanism is not yet understood. This study characterized the microbiome of the gut of Spodoptera frugiperda larvae fed with nine different host plants; sugar cane (M1), maize (M2), onion (M3), cucumber (R1), tomato (R2), sweet potato (R3), cabbage L1), green amaranth (L2), and celocia (L3) by sequencing the theV3-V4 hypervariable region of the 16S rRNA gene using Illumina PE250 NovaSeq system. The results revealed that gut bacterial composition varied among larvae samples fed on different host plants. Three alpha diversity indices revealed highly signicant differences on the gut bacterial diversity of S. frugiperda fed with different host plants.. Analysis of Molecular Variance (AMOVA) and Analysis of Similarity (ANOSIM) also revealed signicant variations on the bacterial communities among the various host plants. Five bacteria phyla (Firmicutes, Proteobacteria, Cyanobacteria, Actinobacteria and Bacteroidetes) were prevalent across the larvae samples. Firmicutes (44.1%) was the most dominant phylum followed by Proteobacteria (28.5%).
