  • Monitoring of Hydrogen Emission from Bacteria in Food, Animals and in the Blood of Humans Suffering from Lyme Disease by a Specific Hydrogen Sensor
    antibiotics Case Report Monitoring of Hydrogen Emission from Bacteria in Food, Animals and in the Blood of Humans Suffering from Lyme Disease by A Specific Hydrogen Sensor Bruno Kolb * , Lorina Riesterer, Anna-Maria Widenhorn and Leona Bier Student Research Centre SFZ, D-88662 Überlingen, Germany; [email protected] (L.R.); [email protected] (A.-M.W.); [email protected] (L.B.) * Correspondence: [email protected]; Tel.: +49-7551-63729 Received: 13 April 2020; Accepted: 16 July 2020; Published: 21 July 2020 Abstract: A novel straightforward analytical technique was developed to monitor the emission of hydrogen from anaerobic bacteria cultured in sealed headspace vials using a specific hydrogen sensor. The results were compared with headspace gas chromatography carried out in parallel. This technique was also applied to investigate the efficacy of chemical antibiotics and of natural compounds with antimicrobial properties. Antibiotics added to the sample cultures are apparently effective if the emission of hydrogen is suppressed, or if not, are either ineffective or the related bacteria are even resistant. The sensor approach was applied to prove bacterial contamination in food, animals, medical specimens and in ticks infected by Borrelia bacteria and their transfer to humans, thus causing Lyme disease. It is a unique advantage that the progress of an antibiotic therapy can be examined until the emission of hydrogen is finished. The described technique cannot identify the related bacteria but enables bacterial contamination by hydrogen emitting anaerobes to be recognized. The samples are incubated with the proper culture broth in closed septum vials which remain closed during the whole process.

  • Antibitoic Treatment for Tuberculosis Induces a Profound Dysbiosis of the Gut Microbiome That Persists Long After Therapy Is Completed
    ANTIBITOIC TREATMENT FOR TUBERCULOSIS INDUCES A PROFOUND DYSBIOSIS OF THE GUT MICROBIOME THAT PERSISTS LONG AFTER THERAPY IS COMPLETED A Thesis Presented to the Faculty of the Weill Cornell Graduate School of Medical Sciences in Partial Fulfillment of the Requirements for the Degree of Masters of Science by Matthew F. Wipperman May 2017 © 2017 Matthew F. Wipperman ABSTRACT Mycobacterium tuberculosis, the cause of Tuberculosis (TB), infects one third of the world’s population and causes substantial mortality worldwide. In its shortest format, treatment of drug sensitive TB requires six months of multidrug therapy with a mixture of broad spectrum and mycobacterial specific antibiotics, and treatment of multidrug resistant TB is much longer. The widespread use of this regimen worldwide makes this one the largest exposures of humans to antimicrobials, yet the effects of antimycobacterial agents on intestinal microbiome composition and long term stability are unknown. We compared the microbiome composition, assessed by both 16S rDNA and metagenomic DNA sequencing, of Haitian TB cases during antimycobacterial treatment and following cure by 6 months of TB therapy. TB treatment does not perturb overall diversity, but nonetheless dramatically depletes multiple immunologically significant commensal bacteria. The perturbation by TB therapy lasts at least 1.5 years after completion of treatment, indicating that the effects of TB treatment are long lasting and perhaps permanent. These results demonstrate that TB treatment has dramatic and durable effects on the intestinal microbiome and highlight unexpected extreme consequences of treatment for the world’s most common infection on human ecology.

  • Lesson 20. Mycobacterium
    Mycobacterium MODULE Microbiology 20 MYCOBACTERIUM Notes 20.1 INTRODUCTION Mycobacterium are slender rods that sometimes show branching filamentous forms resembling fungal mycelium. In liquid cultures they form a mould-like pellicle. Hence the name ‘mycobacteria’, meaning fungus like bacteria. They do not stain readily, but once stained, resist decolourisation with dilute mineral acids. Hence they are called ‘Acid fast bacilli’. They are aerobic, nonmotile, noncapsulated and nonsporing. OBJECTIVES After reading this lesson, you will be able to: z describe the morphology of Mycobacterium tuberculosis & M. leprae z describe the characteristics of Mycobacterium tuberculosis & M. leprae z explain about pathogenesis of Mycobacterium tuberculosis & M. leprae z explain the laboratory diagnosis Mycobacterium tuberculosis & M. leprae The first member of this genus to be identified was Lepra bacillus discovered by Hansen. Koch (1882) isolated the mammalian tubercle bacillus and proved its causative role in tuberculosis. In humans tuberculosis is caused by mycobacterium tuberculosis and also by bovine type called Mycobacterium bovis. The second human pathogenic mycobacterium is the lepra bacillus causing Leprosy. The third group of mycobacterium is a mixed group from varied sources like birds, cold-blooded and warm blooded animals, from skin ulcers, soil, water and other environmental sources. They are called as atypical mycobacteria. They are opportunistic pathogens and can cause many types of diseases. MICROBIOLOGY 203 MODULE Mycobacterium Microbiology 20.2 MYCOBACTERIUM TUBERCULOSIS Morphology M tuberculosis is a straight or slightly curved rod, about 3 X 0.3 µm in size, occurring singly, in pairs or as small clumps. M bovis is usually straighter, shorter and stouter. Tubercle bacilli have been described as Gram positive, even though after Notes staining with basic dyes they resist decolourisation by alcohol even without the effect of iodine.

  • An Astrobiological Study of an Alkaline-Saline Hydrothermal Environment, Relevant to Understanding the Habitability of Mars
    An astrobiological study of an alkaline-saline hydrothermal environment, relevant to understanding the habitability of Mars A thesis submitted for the Degree of Doctor of Philosophy By Lottie Elizabeth Davis Department of Earth Sciences University College London March 2012 1 I, Lottie Elizabeth Davis confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 2 Declaration Abstract The on going exploration of planets such as Mars is producing a wealth of data which is being used to shape a better understanding of potentially habitable environments beyond the Earth. On Mars, the relatively recent identification of minerals which indicate the presence of neutral/alkaline aqueous activity has increased the number of potentially habitable environments which require characterisation and exploration. The study of terrestrial analogue environments enables us to develop a better understanding of where life can exist, what types of organisms can exist and what evidence of that life may be preserved. The study of analogue environments is necessary not only in relation to the possibility of identifying extinct/extant indigenous life on Mars, but also for understanding the potential for contamination. As well as gaining an insight into the habitability of an environment, it is also essential to understand how to identify such environments using the instruments available to missions to Mars. It is important to be aware of instrument limitations to ensure that evidence of a particular environment is not overlooked. This work focuses upon studying the bacterial and archaeal diversity of Lake Magadi, a hypersaline and alkaline soda lake, and its associated hydrothermal springs.
