Two New Cases of Pulmonary Infection by Mycobacterium shigaense, Japan.

ABSTRACT: We report 2 case-patients in Japan with Mycobacterium shigaense pulmonary infections. One patient was given aggressive treatment and the other conservative treatment, according to distinctive radiologic evidence. A close phylogenetic relationship based on whole-genome sequencing was found between strain from the conservatively treated patient and a reference strain of cutaneous origin.

The first case of chronic pulmonary Mycobacterium shigaense infection in an immunocompetent patient.

Project description:Mycobacterium shigaense has recently been recognized as an emerging human pathogen, and is well known as a skin pathogen in immunocompromised individuals. In this report we describe the first case of chronic pulmonary infectious disease caused by M. shigaense in an immunocompetent individual.

Complete Genome Sequence of Mycobacterium shigaense.

Project description:Mycobacterium shigaense is a slowly growing scotochromogenic species and a member of the Mycobacterium simiae complex group. Here, we report the complete sequence of its genome, comprising a 5.2-Mb chromosome. The sequence will represent the essential data for future phylogenetic and comparative genome studies of the Mycobacterium simiae complex group.

Multiple cases of cutaneous Mycobacterium massiliense infection in a "hot spa" in Japan.

Project description:Seven body polishers working in the same "hot spa" presented with multiple red nodules and papules on their hands and forearms. A causative agent was successfully isolated from two of the subjects and from a swab sample collected from the underside of a bed cover in the body-polishing facility. The two cutaneous isolates and the environmental isolate were rapidly growing mycobacteria that formed nonphotochromogenic smooth or smooth/rough colonies on Ogawa egg slants. They were identified as Mycobacterium massiliense by multigenotypic analysis using the 16S rRNA, hsp65, and rpoB genes and the 16S-23S rRNA internal transcribed spacer (ITS) region. However, the use of the 16S rRNA gene sequence and/or DNA-DNA hybridization (DDH Mycobacteria Kit) alone would not distinguish M. massiliense from mycobacteria in the M. chelonae-M. abscessus group. The three isolates were significantly more susceptible to clarithromycin, doxycycline, and minocycline than the M. abscessus and M. bolletii reference strains. One cutaneous isolate and the environmental isolate were in a related cluster by randomly amplified polymorphic DNA PCR (RAPD-PCR). Of the several mycobacterial species found in the day spa, only M. massiliense was isolated from biopsy specimens of the skin lesions, suggesting that this bacterium is a human skin pathogen. This is the first known report of cutaneous M. massiliense infections that could not be attributed to a prior invasive procedure. This is also the first report of M. massiliense infection in Japan.

Report of two fatal cases of Mycobacterium mucogenicum central nervous system infection in immunocompetent patients.

Project description:Neurological infections due to rapidly growing mycobacteria (RGM) have rarely been reported. We recently investigated two unrelated immunocompetent patients, one with community-acquired lymphocytic meningitis and the other with cerebral thrombophlebitis. Mycobacterium mucogenicum was isolated in pure culture and detected by PCR sequencing of cerebrospinal fluid samples. Both patients eventually died. The two isolates exhibited an overlapping antimicrobial susceptibility pattern. They were susceptible in vitro to tetracyclines, macrolides, quinolones, amikacin, imipenem, cefoxitin, and trimethoprim-sulfamethoxazole and resistant to ceftriaxone. They shared 100% 16S rRNA gene sequence similarity with M. mucogenicum ATCC 49650T over 1,482 bp. Their partial rpoB sequences shared 97.8% and 98.1% similarity with M. mucogenicum ATCC 49650T, suggesting that the two isolates were representative of two sequevars of M. mucogenicum species. This case report should make clinicians aware that M. mucogenicum, an RGM frequently isolated from tap water or from respiratory specimens and mostly without clinical significance, can even be encountered in the central nervous system of immunocompetent patients.

Mycobacterium caprae Infection in Captive Borneo Elephant, Japan.

Project description:In 2016, disseminated tuberculosis caused by Mycobacterium caprae was diagnosed in a captive Borneo elephant in Japan. The bacterium was initially identified from clinical isolates. An isolate collected during a relapse showed isoniazid monoresistance and a codon 315 katG mutation.

Landscape of the genome and host cell response of Mycobacterium shigaense reveals pathogenic features.

Project description:A systems approach was used to explore the genome and transcriptome of Mycobacterium shigaense, a new opportunistic pathogen isolated from a patient with a skin infection, and the host response transcriptome was assessed using a macrophage infection model. The M. shigaense genome comprises 5,207,883?bp, with 67.2% G+C content and 5098 predicted coding genes. Evolutionarily, the bacterium belongs to a cluster in the phylogenetic tree along with three target opportunistic pathogenic strains, namely, M. avium, M. triplex and M. simiae. Potential virulence genes are indeed expressed by M. shigaense under culture conditions. Phenotypically, M. shigaense had similar infection and replication capacities in a macrophage model as the opportunistic species compared to M. tuberculosis. M. shigaense activated NF-?B, TNF, cytokines and chemokines in the host innate immune-related signaling pathways and elicited an early response shared with pathogenic bacilli except M. tuberculosis. M. shigaense upregulated specific host response genes such as TLR7, CCL4 and CXCL5. We performed an integrated and comparative analysis of M. shigaense. Multigroup comparison indicated certain differences with typical pathogenic bacilli in terms of gene features and the macrophage response.

Molecular epidemiology of cases of Mycoplasma californicum infection in Japan.

Project description:Bovine mastitis due to Mycoplasma californicum is often accompanied by huge economic losses, and the disease spreads very quickly. An appropriate molecular epidemiological analysis is needed to prevent and control infectious disease, but molecular epidemiological analysis methods for M. californicum have not yet been reported. Here we developed a combination of multiple-locus variable-number tandem repeat analysis (MLVA) and pulsed-field gel electrophoresis (PFGE) methods, which are common genotyping methods for various bacteria, for M. californicum. The MLVA is based on four interspersed repeat units that were found in the M. californicum genome data. The MLVA using these repeat units showed sufficient discriminatory power for a molecular epidemiological analysis; i.e., a Hunter-Gaston diversity index (HGDI) of 0.949, against M. californicum strains in Japan and M. californicum strain ATCC 33461. The PFGE for M. californicum also showed sufficient discriminatory power, with an HGDI of 0.985. Strain ATCC 33461 showed MLVA profiles and pulsotypes that differed greatly from those of strains from Japan. These results indicate that MLVA and PFGE are good tools for identifying M. californicum transmission events more accurately. Our combined MLVA and PFGE analysis suggests the persistence of M. californicum infection among herds in a specific area for a long period of time, as well as the movement of cows and heifers accompanying the expansion of M. californicum infection. Failure to identify asymptomatic infected cows is suspected as one of the central causes of the present M. californicum infection scenario in Japan.
