BACKGROUND Dolutegravir (DTG, S/GSK1349572) is an integrase inhibitor with low nanomolar potency. Susceptibility to dolutegravir and raltegravir was determined for raltegravir-resistant clinical isolates. METHODS Genotypic and phenotypic susceptibility to integrase inhibitors was examined using 39 clinical isolate samples obtained from 18 adults who had exhibited incomplete viral suppression ...

Geographic variation in drug susceptibility among isolates of Streptococcus pneumoniae has influenced national treatment guidelines for community-acquired pneumonia. Whether individual hospital susceptibility data provide reliable and valid information for providers is unclear. We examined the geographic and temporal variability in hospital-reported rates of pneumococcal susceptibility. We surv...

Mupirocin is used for eradicating methicillin-resistant S. aureus (MRSA) nasal colonisation. A plasmid-borne gene, mupA, is associated with high-level mupirocin resistance. After the prevalence of mupA, encoding high-level mupirocin resistance, among all MRSA from a tertiary care centre in the German state of Saxony was approximately 1% for over 15 years (2000-2015), a sharp increase to nearly ...

Identification of Nocardia to the species level is useful for predicting antimicrobial susceptibility patterns and defining the pathogenicity and geographic distribution of these organisms. We sought to develop an identification method which was accurate, timely, and employed tests which would be readily available in most clinical laboratories. We evaluated the API 20C AUX yeast identification ...

interferon- gamma (ifn- γ) is an important immune regulator and inflammatory cytokine which is implicated in the pathogenesis of multiple sclerosis (ms). a single nucleotide polymorphism, t to a, at position +874 in the first intron has previously been shown. this polymorphism is associated with ifn- γ production level. to study the effect of this polymorphism on susceptibility to multiple scle...

The regulation of oxygen supply and consumption by the brain is a complex and dynamic process. The determination of the oxygen saturation of venous blood is an indirect means to assess local tissue oxygen saturation. Quantitatively measuring oxygen saturation is important to characterize the physiological or pathological state of tissue function. Noninvasive and reliable measurements can help t...

BACKGROUND Clinical results of percutaneous needle fasciotomy (PNF) in Japanese patients with Dupuytren's disease are reported. METHODS In this prospective study, 51 patients (103 fingers: 1 index, 9 middle, 47 ring, and 46 small) underwent PNF at 99 metacarpophalangeal (MCP) and 68 proximal interphalangeal (PIP) joints. Patients were assessed postoperatively after 1 day, at 1, 2, 4, 6, and 8...

We have found that amphotericin B is unstable in two commonly employed fungal culture media. This instability leads to inaccuracies in determining the actual level of susceptibility of slow-growing strains that require prolonged incubation for growth. To help compensate for this problem, we have described two rapid methods of susceptibility testing.

We have identified a potential quality control strain of Mycobacterium tuberculosis to monitor isoniazid susceptibility testing. This strain (strain A) has a stable phenotypic low-level resistance to isoniazid, has a mutation of C (-15) --> T in the inhA promoter region, and gave consistent susceptibility test results in 141 laboratories.

Background and Purpose: The incidence of fungal infection as well as candidemia has increased significantly, contributing to morbidity and mortality in the developed countries. The alarming increase in infections with multidrug resistant bacteria is due to overuse of a broad spectrum antimicrobials, which leads to over growth of Candida spp.; thus, enhancing its opportunity to cause the disease...
