Infection, Genetics and Evolution 76 (2019) 104040 Contents lists available at ScienceDirect Infection, Genetics and Evolution journal homepage: www.elsevier.com/locate/meegid Short communication Discovery of a novel Mycobacterium asiaticum PRA-hsp65 pattern T ⁎ William Marco Vicente da Silva , Mayara Henrique Duarte, Luciana Distásio de Carvalho, Paulo Cesar de Souza Caldas, Carlos Eduardo Dias Campos, Paulo Redner, Jesus Pais Ramos National Reference Laboratory for Tuberculosis, Centro de Referência Professor Hélio Fraga, Escola Nacional de Saúde Pública, Fiocruz, RJ, Brazil ARTICLE INFO ABSTRACT Keywords: Twenty-one pulmonary sputum samples from nine Brazilian patients were analyzed by the PRA-hsp65 method PRA-hsp65 for identification of Mycobacterium species and the results were compared by sequencing. We reported a mu- Identification tation at the position 381, that generates a suppression cutting site in the BstEII enzyme, thus leading to a new M. asiaticum PRA-hsp65 pattern for M. asiaticum identification. Nontuberculous mycobacteria (NTM) are opportunistic human pa- widely used for identification of Mycobacterium species. The PRA-hsp65 thogens. NTM are widespread in nature and are found in environmental methodology consists of restriction analysis of a 441 bp PCR fragment sources, including water, soil, and aerosols. They are resistant to most of the hsp65 gene with enzymes BstEII and HaeIII (Campos et al., 2012; disinfectants, including those used in treated water. More than 170 Devulder, 2005; Tamura et al., 2011; Verma et al., 2017). Nowadays, NTM species have been described (http://www.bacterio.net/ M. asiaticum has a single pattern described as type 1 in the PRAsite mycobacterium.html), however, the knowledge about NTM infections database (http://app.chuv.ch/prasite/index.html) based on the fol- is still limited (Chin'ombe et al., 2016; Tortoli, 2014). -

Characteristics of Nontuberculous Mycobacteria from a Municipal Water Distribution System and Their Relevance to Human Infections
CHARACTERISTICS OF NONTUBERCULOUS MYCOBACTERIA FROM A MUNICIPAL WATER DISTRIBUTION SYSTEM AND THEIR RELEVANCE TO HUMAN INFECTIONS. Rachel Thomson MBBS FRACP Grad Dip (Clin Epi) A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy School of Biomedical Sciences Faculty of Health Queensland University of Technology 2013 Principal Supervisor: Adjunct Assoc Prof Megan Hargreaves (QUT) Associate Supervisors: Assoc Prof Flavia Huygens (QUT) i ii KEYWORDS Nontuberculous mycobacteria Water Distribution systems Biofilm Aerosols Genotyping Environmental organisms Rep-PCR iii iv ABSTRACT Nontuberculous mycobacteria (NTM) are environmental organisms associated with pulmonary and soft tissue infections in humans, and a variety of diseases in animals. There are over 150 different species of NTM; not all have been associated with disease. In Queensland, M. intracellulare predominates, followed by M. avium, M. abscessus, M. kansasii, and M. fortuitum as the most common species associated with lung disease. M. ulcerans, M. marinum, M. fortuitum and M. abscessus are the most common associated with soft tissue (both community acquired and nosocomial) infections. The environmental source of these pathogens has not been well defined. There is some evidence that water (either naturally occurring water sources or treated water for human consumption) may be a source of pathogenic NTM. The aims of this investigation were to 1) document the species of NTM that are resident in the Brisbane municipal water distribution system, then 2) to compare the strains of NTM found in water, with those found in human clinical samples collected from Queensland patients. This would then help to prove or disprove whether treated water is likely to be a source of pathogenic strains of NTM for at risk patients. -

MICHIO TSUKAMURA, SHOJI MIZUNO, AND SUM10 TSUKAMURA The National Chubu Hospital, Obu, Aichi, Japan 474 We performed numerical analyses of 155 strains of rapidly growing, scotochrom- ogenic mycobacteria by two different methods; in one method we used 104 characters, and in the other we used 84 characters. The following taxa appeared as distinct clusters: Myco bacterium thermoresistibile, Myco bacterium flavescens, Mycobacterium duvalii, Mycobacterium phlei, “Mycobacterium o buense,” My- co bacterium parafortuitum, Mycobacterium vaccae, Mycobacterium sphagni, “Mycobacterium aichiense,” “Mycobacterium rhodesiae,” Mycobacterium neoaurum, “Mycobacterium chubuense,” “Mycobacterium tokaiense,” and My- cobacterzum komossense (names in quotation marks are not on the Approved Lists of Bacterial Names). M. flavescens strains were divided into two subgroups, one consisting of strains isolated in Japan and the other consisting of strains isolated in Rhodesia and strains received from the American Type Culture Collection, including the type strain of M. flavescens (ATCC 14474). We found that there are many species of rapidly growing, scotochromogenic mycobacteria, and we believe that new species should be recognized and named on the basis of at least three strains. The following species appeared to be distinct from all presently named species: “Mycobacteriumgallinarum,” “Mycobacterium armen- tun,” “Mycobacterium pelpallidurn,” and “Mycobacterium taurus.” However, each of these species was proposed on the basis of only one or two strains. -

Role of Immunotherapy in the Treatment of Tuberculosis
ROLE OF IMMUNOTHERAPY IN THE TREATMENT OF TUBERCULOSIS MURTHY, K.J.R. VIJAYA LAKSHMI, V. and Singh, S. Bhagwan Mahavir Medical Research Centre, 10-1-1, Mahavir Marg, Hyderabad - 500 029. India. ABSTRACT Tuberculosis is caused by Mycobacterium tuberculosis, an intracellular pathogen residing in macrophages. Cell mediated immune (CMI) and delayed type of hypersensitive (DTH) responses play a pivotal role in providing protection to the host. The most important cell is the CD4 T lymphocyte, which is divided into TH1 and TH2 subsets depending on the type of cytokines produced. TH1 cells produce the cytokines interferon-gamma and interleukin-2, which are important for activa- tion of antimycobacterial activities and essential for the DTH response. Grange opines that the immune response in an individual with tuberculous infection gets locked in' to one or other pattern of response viz. TH1 or TH2 response, the latter response leading to tissue damage and progression of disease. Stanford and co-workers conducted several studies on the effectiveness of Mycobacterium vaccae, as an immunotherapeutic agent for tuberculosis. It is non-pathogenic in humans and is thought to be a powerful TH1 adjuvant. A series of small studies pointed that M. vaccae has a beneficial effect and there is enough evidence now to show that its use as an immunotherapeutic agent, as an adjunct to chemotherapy in the treatment of tuberculosis especially at a time when drug resistance is rampant, appears promising. KEY WORDS : Tuberculosis, Drug-Resistance, Immunotherapy, T Cell Responses. ROLE OF IMMUNOTHERAPY IN THE cytokines secreted by the TH1 cell are interferon- TREATMENT OF TUBERCULOSIS gamma (IFN-~,) and interleukin-2 (IL-2). -

We used the GenoType MTBC and CM/AS assays (Hain Lifescience) to perform speciation of 1 096 mycobacterial cultures isolated from respiratory specimens, one culture per patient, in Serbia over a 12-month period. The only species of the Mycobacterium tuberculosis complex (MTBC) identified in our study was M. tuberculosis, with an isolation rate of 88.8%. Ten different species of nontuberculous mycobacteria (NTM) were recognized, and the five most frequently isolated spe- cies were, in descending order, M. xenopi, M. peregrinum, M. gordonae, M. avium and M. chelonae. In total, NTM isolates accounted for 11.2% of all isolates of mycobacteria identified in pulmonary specimens. Our results suggest that routine differentiation among members of the MTBC is not necessary, while routine speciation of NTM is required. Key words: Mycobacterium tuberculosis, nontuberculous mycobacteria, identification, GenoType MTBC, GenoType CM/AS INTRODUCTION M. mungi in banded mongooses (Alexander et al., 2010), and M. orygis in animals of the Bovidae family Currently, the genus Mycobacterium encompasses (van Ingen et al., 2012) have recently been described. 163 species and 13 subspecies described in the list of Although all members of the complex are considered bacterial species with approved names (www.bacte- tubercle bacilli, the most important causative agent rio.cict.fr/m/mycobacterium.html). -

Pavlik1 1Veterinary Research Institute, Brno, Czech Republic 2Regional Institute of Public Health, Brno, Czech Republic 3BioPlus, s.r.o., Brno, Czech Republic ABSTRACT: Mycobacterium arupense is a non-tuberculous, potentially pathogenic species rarely isolated from humans. The aim of the study was to ascertain the spectrum of non-tuberculous mycobacteria within 271 sequenced mycobacterial isolates not belonging to M. tuberculosis and M. avium complexes. Isolates were collected between 2004 and 2009 in the Czech Republic and were examined within the framework of ecological studies carried out in animal populations infected with mycobacteria. A total of thirty-three mycobacterial species were identified. This report describes the isolation of M. arupense from the sputum of three human patients and seven different animal and environmental samples collected in the last six years in the Czech Republic: one isolate from leftover refrigerated organic dog food, two isolates from urine and clay collected from an okapi (Okapia johnstoni) and antelope bongo (Tragelaphus eurycerus) enclosure in a zoological garden, one isolate from the soil in an eagle’s nest (Haliaeetus albicilla) band two isolates from two common vole (Microtus arvalis) livers from one cattle farm. All isolates were identified by biochemical tests, morphology and 16S rDNA sequencing. Also, retrospective screening for M. arupense occurrence within the collected isolates is presented.

The aim of this study was to identify Mycobacterium species in milk samples from cows positive to the comparative intradermal test. Milk samples from 142 cows positive to the comparative intradermal test carried out in 4,766 animals were aseptically collected, cultivated on Lowenstein-Jensen and Stonebrink media and incubated for up to 90 days. Colonies compatible with mycobacteria were stained by Ziehl-Neelsen to detect acid-fast bacilli, while to confirm the Mycobacterium genus, conventional PCR was performed. Fourteen mycobacterial strains were isolated from 12 cows (8.4%). The hsp65 gene sequencing identified M. engbaekii (n=5), M. arupense 1Universidade Estadual Paulista, -
