Comparative analysis of eight leptospiral genomes shows the existence of a core leptospiral genome comprising 1547 genes and 452 conserved genes restricted to infectious species (including L. licerasiae) that are likely to be pathogenicity-related. Comparisons of the functional content of the genomes suggests that L. licerasiae retains several proteins related to nitrogen, amino acid and carbohydrate metabolism which might help to explain why these Leptospira grow well in artificial media compared with pathogenic species. L. licerasiae strains VAR010T and MMD0835 possess two prophage elements. -
Abstract Pultorak, Elizabeth Lauren
ABSTRACT PULTORAK, ELIZABETH LAUREN. The Epidemiology of Lyme Disease and Bartonellosis in Humans and Animals. (Under the direction of Edward B. Breitschwerdt). The expansion of vector borne diseases in humans, a variety of mammalian hosts, and arthropod vectors draws attention to the need for enhanced diagnostic techniques for documenting infection in hosts, effective vector control, and treatment of individuals with associated diseases. Through improved diagnosis of vector-borne disease in both humans and animals, epidemiological studies to elucidate clinical associations or spatio-temporal relationships can be assessed. Veterinarians, through the use of the C6 peptide in the SNAP DX test kit, may be able to evaluate the changing epidemiology of borreliosis through their canine population. We developed a survey to evaluate the practices and perceptions of veterinarians in North Carolina regarding borreliosis in dogs across different geographic regions of the state. We found that veterinarians’ perception of the risk of borreliosis in North Carolina was consistent with recent scientific reports pertaining to geographic expansion of borreliosis in the state. Veterinarians should promote routine screening of dogs for Borrelia burgdorferi exposure as a simple, inexpensive form of surveillance in this transitional geographic region. We next conducted two separate studies to evaluate Bartonella spp. bacteremia or presence of antibodies against B. henselae, B. koehlerae, or B. vinsonii subsp. berkhoffii in 296 patients examined by a rheumatologist and 192 patients with animal exposure (100%) and recent animal bites and scratches (88.0%). Among 296 patients examined by a rheumatologist, prevalence of antibodies (185 [62%]) and Bartonella spp. bacteremia (122 [41.1%]) was high. -

Spirochete Flagella and Motility
biomolecules Review Spirochete Flagella and Motility Shuichi Nakamura Department of Applied Physics, Graduate School of Engineering, Tohoku University, 6-6-05 Aoba, Aoba-ku, Sendai, Miyagi 980-8579, Japan; [email protected]; Tel.: +81-22-795-5849 Received: 11 March 2020; Accepted: 3 April 2020; Published: 4 April 2020 Abstract: Spirochetes can be distinguished from other flagellated bacteria by their long, thin, spiral (or wavy) cell bodies and endoflagella that reside within the periplasmic space, designated as periplasmic flagella (PFs). Some members of the spirochetes are pathogenic, including the causative agents of syphilis, Lyme disease, swine dysentery, and leptospirosis. Furthermore, their unique morphologies have attracted attention of structural biologists; however, the underlying physics of viscoelasticity-dependent spirochetal motility is a longstanding mystery. Elucidating the molecular basis of spirochetal invasion and interaction with hosts, resulting in the appearance of symptoms or the generation of asymptomatic reservoirs, will lead to a deeper understanding of host–pathogen relationships and the development of antimicrobials. Moreover, the mechanism of propulsion in fluids or on surfaces by the rotation of PFs within the narrow periplasmic space could be a designing base for an autonomously driving micro-robot with high efficiency. This review describes diverse morphology and motility observed among the spirochetes and further summarizes the current knowledge on their mechanisms and relations to pathogenicity, mainly from the standpoint of experimental biophysics. Keywords: spirochetes; periplasmic flagella; motility; chemotaxis; molecular motor 1. Introduction Motility systems of living organisms are currently classified into 18 types [1]. Even when focusing on bacteria only, the motility is diverse when bacterial species are concerned [2]. -

The genus contains both important pathogens of livestock as well as commensals. Two species are known to infect humans: B. aalborgi and B. pilosicoli. There is some evidence suggesting that the veterinary pathogenic B. pilosicoli is a potential zoonotic agent, however, since diagnosis in humans is based on histopathology of colon biopsies, species identification is not routinely performed in human materials. Methods: The study population comprised 57 patients with microscopic evidence of Brachyspira infection and 26 patients with no histopathological evidence of Brachyspira infection. Concomitant faecal samples were available from three infected patients. Based on publically available 16S rDNA gene sequences of all Brachyspira species, species-specific primer sets were designed. -

In the Republic of Korea, the population of Korean water deer (KWD, Hydropotes inermis argyropus) has greatly increased from 1982 to 2011, in part, as a result of reforestation programs established following the Korean War when much of the land was barren of trees. Eighty seven Haemaphysalis flava, 228 Haemaphysalis longicornis, 8 Ixodes nipponensis, and 40 Ixodes persulcatus (21 larvae, 114 nymphs, and 228 adults) were collected from 27 out of 70 KWD. -
Comparative Genomics to Investigate Genome Function and Adaptations in the Newly Sequenced Brachyspira Hyodysenteriae and Brachyspira Pilosicoli
Comparative genomics to investigate genome function and adaptations in the newly sequenced Brachyspira hyodysenteriae and Brachyspira pilosicoli Phatthanaphong Wanchanthuek A Thesis presented for the degree of Doctor of Philosophy Murdoch University Australia March 2009 Dedication I would like to dedicate this dissertation to my family and my fiancée Ratchaneekorn. i Comparative genomics to investigate genome function and adaptations in the newly sequenced Brachyspira hyodysenteriae and Brachyspira pilosicoli Phatthanaphong Wanchanthuek Submitted for the degree of Doctor of Philosophy March 2009 ii ABSTRACT Brachyspira hyodysenteriae and Brachyspira pilosicoli are anaerobic intestinal spirochaetes that are the aetiological agents of swine dysentery and intestinal spirochaetosis, respectively. As part of this PhD study the genome sequence of B. hyodysenteriae strain WA1 and a near complete sequence of B. pilosicoli strain 95/1000 were obtained, and subjected to comparative genomic analysis. The B. hyodysenteriae genome consisted of a circular 3.0 Mb chromosome, and a 35,940 bp circular plasmid that has not previously been described. The incomplete genome of B. pilosicoli contained 4 scaffolds. There were 2,652 and 2,297 predicted ORFs in the B. hyodysenteriae and B. pilosicoli strains, respectively. Of the predicted ORFs, more had similarities to proteins of the enteric Clostridium species than they did to proteins of other spirochaetes. Many of these genes were associated with transport and metabolism, and they may have been gradually acquired through horizontal gene transfer in the environment of the large intestine. A construction of central metabolic pathways of the Brachyspira species identified a complete set of coding sequences for glycolysis, gluconeogenesis, a non‐oxidative pentose phosphate pathway, nucleotide metabolism and a respiratory electron transport chain.
