Despite a Mycobacterium tuberculosis control programme and anti-tuberculosis drugs, drug-resistant tuberculosis (DR-TB) is one of the most serious public health issues worldwide. Rapid laboratory diagnosis of M. tuberculosis is needed for the diagnosis of multidrug-resistant (MDR) TB and to find the optimal treatment protocol. The purpose of this study was to detect resistance to rifampicin in new cases of TB using the GeneXpert MTB/RIF (M. tuberculosis/rifampicin) assay and the standard proportional method in west and northwest Iran...

Currently for bacterial identification and classification the rrs gene encoding 16S rRNA is used as a reference method for the analysis of strains of the genus Nocardia. However, it does not have enough polymorphism to differentiate them at the species level. This fact makes it necessary to search for molecular targets that can provide better identification. The sodA gene (encoding the enzyme superoxide dismutase) has had good results in identifying species of other Actinomycetes. In this study the sodA gene is proposed for the identification and differentiation at the species level of the genus Nocardia...

The association of Comamonas kerstersii with peritonitis resulting from the presence of perforated appendix has previously been described by our research team. In the present study, we describe the isolation of this microorganism from two forms of unusual presentations of C. kerstersii infection not previously described in the literature: localized intra-abdominal infection (psoas abscess) and pelvic peritonitis.

We report here the main characteristics of 'Arabia massiliensis' strain Marseille-P3078(T) gen. nov., sp. nov., 'Gordonibacter massiliensis' Marseille-P2775(T) sp. nov. and 'Bacilliculturomica massiliensis' strain Marseille-P3303 gen. nov., sp. nov. The culturomics approach combined with taxonogenomics was used to characterize these strains, which were all isolated from a faecal specimen of a 50-year-old Saudi Bedouin woman.

Campylobacter rectus is rarely associated with invasive infection. Both the isolation and the identification requirements of C. rectus are fastidious, probably contributing to an underestimation of its burden. We report the case of a 66-year-old man who developed several skull base and intracerebral abscesses after dental intervention. Campylobacter rectus was isolated from the brain biopsy. Within 45 minutes of reading the bacterial plate, the strain was accurately identified by MALDI-TOF MS. This rapid identification avoided the extra costs and delays present with 16S rRNA gene sequencing and allowed for a rapid confirmation of the adequacy of the empirical antibiotic treatment...

We used a bacterial culturomics approach combined with taxonogenomics.

The genus Pontibacter is a recent addition to the family Cytophagaceae, phylum Bacteroidetes. Previous reports of its cultivation and molecular detection are from a variety of environmental sources, including marine and desert habitats. We report the first description of a Pontibacter sp., which was initially identified as Elizabethkingia meningoseptica, isolated from a human clinical specimen. On the basis of 16S rRNA gene sequence, unique mass spectral profile and phenotypic characterization, this isolate represents a novel species within the genus Pontibacter that has been named Pontibacter altruii, sp...

Nickel-resistant bacteria have been isolated so far only in contaminated soils and wastewaters polluted with different industrial sources. The aim of our study was to determine if nickel-resistant bacteria could also be isolated from human samples. In this brief communication, we describe how we were able to isolate human bacterial strains that grew without oxygen and in the presence of high concentrations of nickel. The identification was made by phenotypic and genetic techniques. The bacterial sequences have been deposited in the NCBI database repository...

Tularaemia is a highly contagious infectious zoonosis caused by the bacterial agent Francisella tularensis. The aim of this study was to investigate the presence of antibodies to F. tularensis in febrile patients in northeastern Kenya. During 2014-2015, 730 patients were screened for anti-F. tularensis antibodies using a combination of ELISA and Western blot. Twenty-seven (3.7%) individuals were positive for F. tularensis. Tularaemia was not suspected by the treating clinicians in any of them. Our results suggest that tularaemia may be present in Kenya but remain unreported, and emphasizes the need for local clinicians to broaden their diagnostic repertoire when evaluating patients with undifferentiated febrile illness...

Microbial culturomics, which investigates microbial diversity by combining diversified culture conditions, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rDNA identification, allowed to identify five new species within the Bacillus genus. Bacillus massiliglaciei strain Marseille-P2600(T), Bacillus mediterraneensis strain Marseille-P2384(T), Bacillus massilinigeriensis strain Marseille-P2366(T), Bacillus tuaregi strain Marseille-P2489(T) and Bacillus phocaeensis strain SIT16(T) are each the type strain of the corresponding bacterial species...

We report the genome sequence of Bifidobacterium animalis subspecies lactis BL3, which has preventive properties on acute colitis and colon cancer. The genome of BL3, which was isolated from Korean faeces, consisted of a 1 944 323 bp size single chromosome, and its G+C content was 60.5%. Genome comparison against the closest Bifidobacterium animalis strain revealed that BL3 had particularly different regions of four areas encoding flavin-nucleotide-binding protein, transposase, multidrug ABC transporter and ATP binding protein...

Staphylococcus spp. is a major cause of nosocomial infection and sepsis. However, increasing drug resistance is becoming a challenge to microbiologists. The purpose of this study was to identify and determine antimicrobial resistance phenotypes and drug resistance genes of clinical coagulase-negative staphylococci (CoNS) isolates at Mae Sot Hospital in Tak province, Thailand. A total of 229 CoNS isolates were collected from clinical specimens during two periods in 2014 and in 2015. Staphylococcus haemolyticus was the most prevalent species (37...

One hundred thirty-six isolates, 88 human and 48 environmental, that met the requirements to belong to the genus Paenibacillus were identified using a polyphasic taxonomic approach known as 16S rRNA plus phenotypic traits. Thirty-seven Paenibacillus species were identified; some had not been previously reported from clinical samples. The main species were P. pabuli (13 isolates), P. provencensis (11), P. phoenicis (9) and P. lautus (8). P. pabuli (11/13) and P. provencensis (8/11) were mainly environmental isolates, while P...

ST121/agr-IV methicillin-susceptible Staphylococcus aureus was isolated from a patient of septic arthritis (synovial fluid, blood, skin and nasal cavity). Although the Panton-Valentine leukocidin (PVL) gene was negative, this isolate harboured a gene encoding a variant of bone sialoprotein-binding protein with a shortened SD-repeat region.
