In this study, 210 intestinal Escherichia (E.) coli isolates from enteropathogenic diseased pigs were screened for their virulence factors (F4, F5, F6, F18, STa, STb, LT, STx2e and intimin) by PCR and serogrouped by slide-agglutination (O8:K87, O45, O138:K81, O139:K82, O141:K85, O147:K89, O157 and O149:K91). In total, 24.8% enterotoxigenic E. coli, 7.1% enteropathogenic E. coli and 5.2% oedema ...

INTRODUCTION Hodgkin's disease is highly curable by radiotherapy and/or chemotherapy, but refractory disease or early relapses are rarely cured by conventional salvage therapy. CASE PRESENTATION We report a case of a 20-year-old Caucasian man, with a biopsy-proven intrapulmonary relapse of Hodgkin's disease, for whom salvage chemotherapy was administered. During salvage chemotherapy intense i...

Neurofibromatosis type I (NF1) is an autosomal dominant multisystem disorder. Patients with NF1 are at increased risk for developing both benign and malignant tumours. We report the case of a patient with histologically documented NF1, who underwent F18-FDG-PET/CT for staging purposes. The study revealed intense uptake at multiple masses located at the thighs (the largest presented SUV max of 6...

We compared and analyzed the expression of the BPI gene of Sutai piglets ranging from newborn to post-weaning days 8, 18, 30, and 35 by the real-time PCR method, in order to determine if it is involved in protection against disease caused by ETEC F18. There was a significant difference between 18 and 35-day expression in the jejunum. There were also significant differences between 35-day expres...

Polymerase chain reaction for five fimbriae (K88, K99, 987P, F41, F18), two heatstable enterotoxins (STa, STb), one heatlabile enterotoxin (LT), and Shiga-like toxin type II (SLT) was performed on Escherichia coli isolates to determine their genotype among isolates from weaned pigs with diarrhea and/or edema disease in North Carolina. A total of 175 isolates were tested. All but two isolates po...

inflammatory process improves, FDG uptake should be diminished, at least in the affected vessels. This was confirmed in the two patients for whom we have a follow-up F18-FDG-PET. Nevertheless, this pathophysiological basis can cause some false-positive results, as FDG uptake can occur in atherosclerotic lesions with an accumulation of inflammatory cells. Usually these images are less clearly po...

We analyzed LTβR mRNA expression in piglets from birth to weaning and compared the differential expression between Escherichia coli F18-resistant and sensitive populations to determine whether this gene could be used as a genetic marker for E. coli F18 resistance. Sutai piglets of different age groups (8, 18, 30, and 35 days; N = 4 each) and piglets demonstrating resistance/sensitivity to E. co...

Post-weaning diarrhea and edema disease caused by F18 fimbriated E. coli are important diseases in newly weaned piglets and lead to severe production losses in farming industry. Protective treatments against these infections have thus far limited efficacy. In this study we generated nanobodies directed against the lectin domain of the F18 fimbrial adhesin FedF and showed in an in vitro adherenc...

as a nuclear approach, positron emission tomography (pet) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. there are certain limitations to this technique such as normal tissue uptake. therefore, it has been recommended that patients prepare before scanning. fasting for a short while before pet imaging is an exampl...

Background: Bacteriophages are viruses that infect bacteria and therefore are widespread in nature. Those that lyse the pathogen Salmonella enterica serovar Enteritidis (SE) should be expected in niches in which this bacterium thrives, among others the avian egg. Furthermore, bacteriophages could remain viable in this milieu. Results: Upon artificially infecting hen eggs with the SE bacteriopha...
