A Gram-staining-negative, non-motile, aerobic and rod-shaped bacterium, strain Ra1T, was isolated from the gut of a wood-feeding lower termite, Reticulitermes aculabialis. Phylogenetic analysis of 16S rRNA gene sequences showed that the strain was closely related to Chryseobacterium rigui JCM 18078T (96.7%). Growth was observed at 15-45℃ (optimum 30℃), at pH 6.0-9.0 (optimum pH 8.0) and in the presence of 0-2% NaCl (optimum 0%). The DNA G+C content of strain Ra1T was 39.9 mol%. The cells contained MK-6 as the sole respiratory quinone and the major fatty acids were iso-C15:0, iso-C17:0, summed feature 3 (comprising C16:1ω6c and/or C16:1ω7c) and summed feature 9 (comprising C16:0 10-methyl and/or iso-C17:1ω9c)...

INTRODUCTION: Diphtheroids are defined as aerobic, non-sporulating, pleomorphic Gram-positive bacilli which are more uniformly stained than Corynebacterium diphtheriae, lack the metachromatic granules and are arranged in a palisade manner. They are usually commensals of the skin and mucous membranes. They differ from C.diphtheriae in biochemical rea-ctions as well as in toxin production. Since, they are usually found as commensals on the skin, they are often considered as mere contaminants when isolated from clinical samples...

Encephalitozoon cuniculi is an important microsporidian pathogen that is considered an emergent, zoonotic, and opportunistic. It infects both domestic and laboratory rabbits, generating severe chronic interstitial and granulomatous nephritis with fibrosis and granulomatous encephalitis. Encephalitozoonosis is diagnosed in paraffin-embedded sections by examining the spores in the host tissues. The spores are difficult to observe when the samples are stained with hematoxylin and eosin (H&E), particularly when there is an inflammatory reaction and tissue damage...

BACKGROUND: Cell blocks are widely used in human cytopathology. Several techniques have been proposed to convert fluid specimens into solid material, which after embedding in paraffin can be used for histochemistry, immunohistochemistry, or molecular testing. In contrast, only in the last few years, have cell blocks begun to be used in the veterinary field. OBJECTIVES: The purpose of the study was to present the production and features of cell tube blocks (CTB) with veterinary liquid samples...

The entomopathogen "Corynebacterium okanaganae" was described by Lüthy in 1974 but the name was never validly published. Phylogenetic analysis employing 16S rRNA gene sequences demonstrate that "Corynebacterium okanaganae" is not a member of the genus Corynebacterium but related to members of the Microbacteriaceae being most closely related to, but distinct from, members of the genera Rathayibacter, Mycetocola and Curtobacterium. The bacterium is an aerobic, Gram-positive staining, rod-shaped actinobacterium with the cell-wall peptidoglycan based on 2,4, diaminobutyric acid as the diagnostic diamino acid...

Making a prompt and accurate diagnosis of genital tract infections is the key to instituting appropriate treatment and the linchpin of sexually transmitted infection control. We present a brief history, not covering syphilis, of diagnostic events for each of six bacteria and one protozoan from the time of discovery up to the molecular revolution. The latter is touched upon but its impact will form the substance of a further presentation. Here, hindsight is helpful in understanding the way in which progress was made over 135 years, often when microbiology, not even seen as a distinct discipline, had a difficult time in providing what was required in terms of dependable diagnostic techniques...

The essential first step in bacterial colonization is adhesion to the host epithelial cells. The early host-responses post-bacterial adhesions are still poorly understood. Early growth response 1 (EGR1) is an early response transcriptional regulator that can be rapidly induced by various environmental stimuli. Several bacteria can induce EGR1 expression in host cells, but the involved bacterial characteristics and the underlying molecular mechanisms of this response are largely unknown. Here, we show that EGR1 can be induced in host epithelial cells by different species of bacteria independent of the adherence level, Gram-staining type and pathogenicity...

Accurate diagnosis of bacterial meningitis (BM) relies on cerebrospinal fluid (CSF) Gram stain and bacterial culture, which often present high false-negative rates because of the antibiotic abuse. Thus a novel and reliable diagnostic biomarker is highly required. Procalcitonin (PCT) is well demonstrated to be specifically produced from peripheral tissues by bacterial infection, which makes it a potential candidate. Here, we performed a prospective clinical study comprising a total of 143 patients to investigate the diagnostic value of CSF PCT, serum PCT and other conventional biomarkers for BM...

The GID SVF-1 and GID SVF-2 are closed-system, disposable, scalable cellular isolation devices designed for isolating the human adipose-derived stromal vascular fraction (hSVF) from lipoaspirates at the point-of care. The purpose of this study was to characterize the device performance with respect to cell yield and viability of the hSVF, as well as the hSVF purity and cellular composition. Our results demonstrate that adipose-derived SVF can be safely obtained using both devices and standardized methods, yielding cells that are free of bacterial contaminants as measured by endotoxin levels, gram stain and culture...

Perivascular stem cells (PSCs) are the natural ancestors of mesenchymal stem cells (MSCs) and are the stem cells responsible for homeostasis and repair in vivo. Prospectively identified and isolated PSCs have demonstrated increased plasticity and osteogenic potential. Cells from the infrapatellar fat pad (IFP) have demonstrated increased chondrogenic potential compared with those from subcutaneous fat. This research assessed the chondrogenic potential of IFP PSCs compared with MSCs from the IFP and bone marrow...
