The molecular taxonomy of the M. terrae complex causing tenosynovitis http://jcm.asm.org/ has not been established despite approximately 50 previously reported cases. We evaluated 26 isolates of the M. terrae complex associated with tenosynovitis or osteomyelitis recovered between 1984 and 2014 from 13 states, including 5 isolates reported in 1991 as M. nonchromogenicum by nonmolecular methods. The isolates belonged to three validated species, one new proposed species, and two novel related strains. The majority of isolates (20/26, or 77%) belonged to two recently described species: Myco- bacterium arupense (10 isolates, or 38%) and Mycobacterium heraklionense (10 isolates, or 38%). Three isolates (12%) had 100% sequence identity to each other by 16S rRNA and 99.3 to 100% identity by rpoB gene region V sequencing and represent a previ- ously undescribed species within the M. terrae complex. There were no isolates of M. terrae or M. nonchromogenicum, including among the five isolates reported in 1991.

Svobodova2, A. Ettlova3, I. Slana1, V. Mrlik1, I. 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,

In this study, we investigated the frequency and clinical implication of the rarely isolated NTM from respiratory specimens. Methods: Patients with NTM isolated from their respiratory specimens between July 1, 2010 and June 31, 2012 were screened for inclusion. Rare NTM were defined as those NTM not falling within the group of eight NTM species commonly identified at our institution: Mycobacterium avium, M. intracellulare, M. abscessus, M. massiliense, M. fortuitum, M. kansasii, M. gordonae, and M. peregrinum. Clinical, radiographic and microbiological data from patients with rare NTM were reviewed and analyzed. Results: During the study period, 73 rare NTM were isolated from the respiratory specimens of 68 patients. Among these, M. conceptionense was the most common (nine patients, 12.3%). The median age of the 68 patients with rare NTM was 68 years, while 39 of the patients were male. Rare NTM were isolated only once in majority of patient (64 patients, 94.1%). Among the four patients from whom rare NTM were isolated two or more times, only two showed radiographic aggravation caused by rare NTM during the follow-up period. Conclusions: Most of the rarely identified NTM species were isolated from respiratory specimens only once per patient, without concomitant clinical aggravation.

Although the American Thoracic Society published the guidelines for diagnosis of NTM pulmonary disease (NTM-PD), the diagnosis is still difficult. In the first part of the study, we collected data on NTM isolates in the Mycobacteriology Laboratory of Careggi Hospital (Florence, Italy) and analysed the epidemiological data of NTM isolates. Then, to analyse the risk factors associated to NTM-PD, we studied the presence of ATS/IDSA criteria for NTM-PD in patients who had at least one positive respiratory sample for NTM and were admitted to the Infectious Disease Unit and the Section of Respiratory Medicine.

BMC Public Health 2011, 11:320 http://www.biomedcentral.com/1471-2458/11/320 RESEARCHARTICLE Open Access Isolation of non-tuberculous mycobacteria from pastoral ecosystems of Uganda: Public Health significance Clovice Kankya1,2*, Adrian Muwonge2, Berit Djønne3, Musso Munyeme2,4, John Opuda-Asibo1, Eystein Skjerve2, James Oloya1, Vigdis Edvardsen3 and Tone B Johansen3 Abstract Background: The importance of non-tuberculous mycobacteria (NTM) infections in humans and animals in sub- Saharan Africa at the human-environment-livestock-wildlife interface has recently received increased attention. NTM are environmental opportunistic pathogens of humans and animals. Recent studies in pastoral ecosystems of Uganda detected NTM in humans with cervical lymphadenitis and cattle with lesions compatible with bovine tuberculosis. However, little is known about the source of these mycobacteria in Uganda. The aim of this study was to isolate and identify NTM in the environment of pastoral communities in Uganda, as well as assess the potential risk factors and the public health significance of NTM in these ecosystems. Method: A total of 310 samples (soil, water and faecal from cattle and pigs) were examined for mycobacteria. Isolates were identified by the INNO-Lipa test and by 16S rDNA sequencing. Additionally, a questionnaire survey involving 231 pastoralists was conducted during sample collection. Data were analysed using descriptive statistics followed by a multivariable logistic regression analysis. Results: Forty-eight isolates of NTM were detected; 25.3% of soil samples, 11.8% of water and 9.1% from animal faecal samples contained mycobacteria. Soils around water sources were the most contaminated with NTM (29.8%).

    [Downloaded free from http://www.ijmyco.org on Monday, June 4, 2018, IP: 200.41.178.226] Original Article Utilization of Molecular and Conventional Methods for the Identification of Nontuberculous Mycobacteria Isolated from Different Water Sources Claudia Andrea Tortone1, Martín José Zumárraga2, Andrea Karina Gioffré2, Delia Susana Oriani1 1Laboratory of Mycobacteria, Faculty of Veterinary Sciences, National University of La Pampa, General Pico, La Pampa, 2Biotechnology Institute, National Institute of Agricultural Technology (INTA), Hurlingham, Buenos Aires, Argentina Abstract Background: The environment is the nontuberculous mycobacteria (NTM) reservoir, opportunistic pathogens of great diversity and ubiquity, which is observed in the constant description of new species capable of causing infection. Since its introduction, molecular methods are essential for species identification. Most comparative studies between molecular and conventional methods, have used isolated strains from clinical samples. Methods: The aim of this study was to evaluate the usefulness of molecular methods, especially the hsp65‑PRA (PCR‑Restriction Enzyme Analysis), and biochemical tests in the identification of NTM recovered from water of different origins, using the sequencing of 16S rRNA and hsp65 genes as assessment methods of the previous ones. Species identification was performed for all 56 NTM isolates what were recovered from 32 (42.1%) positive water samples, using conventional phenotypic methods, hsp65‑PRA, partial sequencing of 16S rRNA and sequencing

Host exposure to NTM may impact on cross-reactive immune responsiveness which may affect diagnosis of bovine tuberculosis and may also play a role in the variability of the efficacy of Mycobacterium bovis BCG vaccination against tuberculosis. In this study we characterized 10 NTM isolates originating from water, soil, nasal swabs of cattle and African buffalo as well as bovine tissue samples. These isolates were previously identified during an NTM survey and were all found, using 16S rDNA sequence analysis to be closely-related to Mycobacterium moriokaense.

  • Extra-Pulmonary Nontuberculous Mycobacterial Infections: 16 Year Retrospective Analysis at an Academic Institution in Cincinnati, Ohio
    Extra-pulmonary Nontuberculous Mycobacterial Infections: 16 year retrospective analysis at an academic institution in Cincinnati, Ohio. A thesis submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Master of Science in Clinical & Translational Research In the Department of Environmental Health Division of Epidemiology of the College of Medicine July, 2017 by Kiran Afshan MBBS, University of Karachi, Pakistan, August, 2006 Committee Chair: Erin Haynes, DrPH Abstract Title: Extra-pulmonary Nontuberculous Mycobacterial Infections: 16 year retrospective analysis at an academic institution in Cincinnati, Ohio. Authors: Afshan K, Smulian AG, Jandarov RA, Haglund L. Background: Nontuberculous mycobacterial infections (NTM), once considered a rare cause of human disease, are now increasingly recognized in clinical practice. We have sought to identify clinical and demographic characteristics of the extra-pulmonary NTM infections presenting at our institution during 2000-2015. Methods: Records of patient with culture proven extra-pulmonary NTM infections were reviewed. Demographic information, clinical and microbiologic characteristics and treatment outcomes were captured. Results: 58 cases of extra-pulmonary NTM infections identified were classified into cutaneous 9 (15.52%), soft tissue 38 (65.52%), osteo-articular 9 (15.52%) and disseminated infections 2 (3.45%). 52% of the cases were male. Median age at diagnosis was 52years. All cases were diagnosed based on culture positivity.
