mycobacterium parascrofulaceum sp. nov., novel slowly growing, scotochromogenic clinical isolates related to mycobacterium simiae.a group of pigmented, slowly growing mycobacteria identified by 16s rrna gene sequencing as 'mcro 33' (genbank accession no. af152559) have been isolated from several clinical specimens in various laboratories across canada. genotypically, the organism is most closely related to mycobacterium simiae. however, it presents with a similar phenotypic profile to mycobacterium scrofulaceum. several reference strains obtained from atcc and tmc culture collections, previously identified as m. scrofulace ...200415388708
infections due to the newly described species mycobacterium parascrofulaceum.we report on four cases of infection by the recently described species mycobacterium parascrofulaceum. in two cases the mycobacterium was isolated from aids patients, while in the others it was responsible for pulmonary disease in elderly men. our findings suggest that m. parascrofulaceum is an opportunistic pathogen, like many other nontuberculous mycobacterial species.200516082003
mycobacterium parascrofulaceum in acidic hot springs in yellowstone national park.mycobacterium parascrofulaceum was found in norris geyser basin, yellowstone national park, in a system composed of two acidic (ph 3.0) springs with temperatures between 56 degrees c at the source and 40 degrees c at the confluence of both springs. growth and survival assays at 56 degrees c for 60 days were performed, confirming the origin of the strain.200717557859
revival and emended description of 'mycobacterium paraffinicum' davis, chase and raymond 1956 as mycobacterium paraffinicum sp. nov., nom. rev.the omission of the name 'mycobacterium paraffinicum' from the approved lists of bacterial names was due to phenotypic confusion surrounding a close relationship with mycobacterium scrofulaceum. correspondingly, 'm. paraffinicum' strains grew slowly in > 7 days, stained acid-alcohol-fast and produced yellow-pigmented, smooth, waxy colonies in the dark at an optimal temperature of 35°c. however, 'm. paraffinicum' strains demonstrated no activity for urease, nicotinamidase or pyrazinamidase and la ...201019915104
pulmonary mycobacterium parascrofulaceum infection as an immune reconstitution inflammatory syndrome in an aids patient.nontuberculous mycobacterial (ntm) infection in hiv (human immunodeficiency virus)-infected patients who have started highly active antiretroviral therapy (haart) is well known to be one scenario of immune reconstitution inflammatory syndrome (iris). we encountered the first case in japan of an hiv-infected patient with pulmonary mycobacterium parascrofulaceum infection as iris. a 34 year-old man with acquired immunodeficiency syndrome (aids) was receiving highly active antiretroviral therapy. l ...201020720366
immunopathological characteristics of immune reconstitution inflammatory syndrome caused by mycobacterium parascrofulaceum infection in a patient with aids.immune reconstitution inflammatory syndrome (iris) caused by mycobacterium in patients with aids is often experienced in clinical practice. there is, however, a paucity of data documenting the histopathological findings and the pathogenesis. we determined the immunopathological characteristics of iris associated with mycobacterium parascrofulaceum infection in an aids patient. a patient presented with pulmonary lymphadenitis and involvement of the pulmonary lingular segment. portions of the invo ...201121377277
chronic pelvic pain due to mycobacterium parascrofulaceum in an iranian patient: first report of isolation and molecular characterization from asia. 201121503412
rapid molecular identification of mycobacterial species in positive culture isolates using the biochip test.patients infected with non-tuberculous mycobacteria usually fail treatment due to erroneous diagnoses. early detection of mycobacterial species is essential for adequate case management.201122118178
drug susceptibility testing and pharmacokinetics question current treatment regimens in mycobacterium simiae complex disease.the mycobacterium simiae complex bacteria can cause opportunistic infections in humans. in the case of definite disease, there are no evidence-based treatment regimens and outcomes are very disappointing. to increase the evidence base underpinning treatment regimens for m. simiae complex disease, drug susceptibility patterns and rifampicin/ethambutol synergy were assessed retrospectively in 69 clinical m. simiae complex isolates from 60 patients (22 patients with m. simiae, 24 with mycobacterium ...201122099521
Cloning and expression of a gene with phospholipase B activity from Pseudomonas fluorescens in Escherichia coli.A gene from Pseudomonasfluorescens BIT-18 encoding a protein with phospholipase B activity (Pf-PLB) was cloned in E. coli BL21 (DE3). The open reading frame consists of 1272bp and potentially encodes a protein of 423 amino acid residues with a calculated molecular mass of 45.8kDa. The nucleotide sequence of Pf-PLB is 45%, 42%, 41%, 40%, 33%, and 31% identical to that of Bifidobacteriumanimals, Mycobacteriumparascrofulaceum, Acidobacteriumcapsulatum, Lactobacillusjohnsonii, Moraxellabovis, and Mo ...201222078969
extraordinary solute-stress tolerance contributes to the environmental tenacity of mycobacteria.mycobacteria are associated with a number of well-characterized diseases, yet we know little about their stress biology in natural ecosystems. this study focuses on the isolation and characterization of strains from yellowstone national park (ynp) and glacier national park (gnp; usa), the majority of those identified were mycobacterium parascrofulaceum, mycobacterium avium (ynp) or mycobacterium gordonae (gnp). generally, their windows for growth spanned a temperature range of > 60 °c; selected ...201526059202
respiratory tract isolation of mycobacterium europaeum following influenza infection in an immunocompromised patient: a case report.mycobacterium europaeum, a slow-growing nontuberculous mycobacteria belonging to the mycobacterium simiae complex, was described after the seminal characterization of five isolates collected from three sputum specimens and a jaw gland biopsy in italy, greece and sweden. five respiratory tract isolates were further reported in iran. here, we report the first isolation of m. europaeum in france, in the respiratory tract of a patient co-infected with human immunodeficiency virus and hepatitis c vir ...201425539638
mycobacterium yongonense sp. nov., a slow-growing non-chromogenic species closely related to mycobacterium intracellulare.a slow-growing non-chromogenic mycobacterium was isolated from a patient with pulmonary disease. phenotypically, strain 05-1390(t) was similar to mycobacterium intracellulare atcc 13950(t). the 16s rrna gene sequence (1385 bp) of strain 05-1390(t) showed a high degree of similarity to those of the m. intracellulare complex, namely mycobacterium marseillense 5351974(t) (100 %), m. intracellulare atcc 13950(t) (99.8 %) and mycobacterium chimaera dsm 44623(t) (99.9 %). phylogenetic analysis based o ...201322427442
molecular evidence of lateral gene transfer in rpob gene of mycobacterium yongonense strains via multilocus sequence analysis.recently, a novel species, mycobacterium yongonense (dsm 45126(t)), was introduced and while it is phylogenetically related to mycobacterium intracellulare, it has a distinct rna polymerase β-subunit gene (rpob) sequence that is identical to that of mycobacterium parascrofulaceum, which is a distantly related scotochromogen, which suggests the acquisition of the rpob gene via a potential lateral gene transfer (lgt) event. the aims of this study are to prove the presence of the lgt event in the r ...201323382812
