Outbreaks of hypervirulent strains of Clostridium difficile began to be reported in healthcare facilities worldwide around 20 years ago. Concurrently, trehalose became a common additive used by the global food industry. A new study provides evidence that these two observations are a linked phenomenon (Collins et al., 2018).

Clostridioides difficile is the main etiological agent of diarrhea associated with health care, it produces toxins and glutamate dehydrogenase (GDH), an enzyme that is highly conserved in this species. Rapid diagnosis and effective treatment produce prompt improvement of the patient and subsequent control of the microorganism spread. There are several techniques whose results are interpreted in the context of algorithms. However, the optimal diagnostic method is yet unknown. The performance of GDH as a screening test for the diagnosis of C...

This report describes a dog infected with Hepatozoon canis, the first canine infection in the Republic of Korea. A 2-year-old intact male Maltese dog presented with anorexia and depression. Physical examinations revealed mild dehydration and hyperthermia (39.8°C), and blood analysis showed pancytopenia. Diff-Quik staining of blood smear specimens showed the presence of ellipsoidal shaped structures (gamonts of H. canis) within a small number of neutrophils. Real-time PCR analysis using whole blood confirmed infection by H...

BACKGROUND: Erythropoietin, as a principal hormone promotes red blood cell production in bone marrow. Varieties of erythropoietin biosimilar are being produced by recombinant DNA technology in cell cultures. The detection or quantifi cation of these molecules are being performed by diff erent methods which some of theme such as Western blot and enzymelinked immunosorbent assay (ELISA) require specifi c antibodies. High cost, inappropriate shipping (cold chain failures), reduced sensitivity and thus poor detection performance are common pitfalls of using commercial kits for performing immunological tests...

The Verigene(®)Clostridium difficile nucleic acid test (Verigene(®) CDF test) is an automatic and rapid detection system for the genes encoding tcdA, tcdB, binary toxin, and the single nucleotide deletion at base pair 117 in the tcdC based on microarray and PCR amplification. We compared the performance of the Verigene(®) CDF test to that of two enzyme immunoassays, C. DIFF QUIK CHEK COMPLETE and X/Pect Toxin A/B, using 118 specimens. We found overall concordance rates of 81.4% and 78.8% between C. DIFF QUIK CHEK COMPLETE and Verigene(®) CDF test, and X/Pect Toxin A/B and Verigene(®) CDF test...

BACKGROUND AND AIM: Clostridium difficile is a major cause of health care-associated infection, but disagreement between diagnostic tests is an ongoing barrier to clinical decision-making. Conventional enzyme immunoassay (EIA) for toxin detection is currently the most frequently used technique for C. difficile infection (CDI) diagnosis, but its low sensitivity makes the development of an alternative strategy necessary for improving the diagnosis in developing countries. METHODS: Between years 2011 and 2015, 154 stool samples from patients with antibiotic-associated diarrhea were examined by toxigenic culture and EIA for the diagnosis of CDI...

PURPOSE OF THE REVIEW: Review tests available for detection of Clostridium difficile (C. Diff) induced disease, including when such tests should be done in children and how they should be interpreted. RECENT FINDINGS: Multiple tests are available for detecting disease due to C. diff. These include colonoscopy and stool analysis. Colonoscopy with biopsy is the most sensitive test for detecting the presence of colitis. The toxins produced by the C. diff. (toxin A, toxin B, and binary toxin) are the agents that cause injury and disease...

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) is a low-grade malignant lymphoma that appears frequently in the stomach, but other sites can also be involved: the intestinal tract, lungs, head, neck, skin, thyroid, breasts and liver. Recently, epidemiological evidences support the idea that there is an association between hepatitis C and B-cell non-Hodgkin lymphomas (that include MALT as a subtype). Primary non-Hodgkin lymphomas confi ned only to the liver are very rare (only 0...

There is no stand-alone Clostridium difficile diagnostic that can sensitively and rapidly detect fecal free toxins. We investigated the performance of the C. difficile PCR cycle threshold (CT ) for predicting free toxin status. Consecutive stool samples (n = 312) positive for toxigenic C. difficile by the GeneXpert C. difficile/Epi tcdB PCR assay were tested with the rapid membrane C. Diff Quik Chek Complete immunoassay (RMEIA). RMEIA toxin-negative samples were tested with the cell cytotoxicity neutralization assay (CCNA) and tgcBIOMICS enzyme-linked immunosorbent assay (ELISA)...
