Babesiosis is an emerging tick-borne disease transmitted by the hard tick Ixodes scapularis, which also transmits Lyme disease. Better gradation of prognostic indicators are needed to determine which patients may develop serious complications requiring hospitalization, and to provide early guidance on appropriate therapy. In this study, we evaluated 128 patients with smear or real time polymerase chain reaction-confirmed Babesia microti infections over a period of 16 years. Patients with asplenia or immunocompromising conditions were more likely to have severe infection (P < 0...

Porcine epidemic diarrhea virus emerged in the US is known to suppress the type I interferons response during infection. In the present study using porcine epithelial cells, we showed that PEDV inhibited both NF-κB and proinflammatory cytokines. PEDV blocked the p65 activation in infected cells and suppressed the PRD II-mediated NF-κB activity. Of the total of 22 viral proteins, nine proteins were identified as NF-κB antagonists, and nsp1 was the most potent suppressor of proinflammatory cytokines. Nsp1 interfered the phosphorylation and degradation of IκBα, and thus blocked the p65 activation...

Neuroendocrine tumors (NETs) consist of a diverse family of malignancies, which are derived from neuroendocrine cells, most commonly originating from the gastroenteropancreatic (GEP) tract or the bronchopulmonary system. In general, NETs are more indolent than epithelial tumors, with median survival rates of longer than 30 months. The upregulation of mTOR pathway has been shown to play a pivotal role in NET pathogenesis. Inhibition of mTOR protein with everolimus represents a progress in the treatment of advanced NETs...

Porcine epidemic diarrhea (PED) is an emerging disease of pigs in several countries. In the present study, individual sow productivity of Berkshire sows exposed to PED virus at different stages of production was compared. On a commercial farrow-to-finish farm in Kagoshima Prefecture, Japan, the clinical presence of PED was observed in the farrowing barn on January 6, 2014, and all gilts and sows were immunized on January 9, except those in the farrowing barn. The sows were categorized into six groups based on the period in which they were exposed to PED virus: between days 0-30 (G1), 31-60 (G2), 61-90 (G3), or after 91 days of pregnancy (G4), during lactation (L), and after weaning (W)...

Colon ischemia following aortic reconstruction is a severe complication with an incidence of 1% to 2% of the operated patients; this infrequent complication will be lethal for nearly half of these patients. Commonly, colon ischemia may be an intraoperative observation or an early postoperative finding. However, in the case presented here, sigmoid rupture and small and large intestine communication was revealed 3 months following repair of the abdominal aorta. A 71-year-old man, following open repair of an abdominal aortic aneurysm, went home on the fifth postoperative day...

Clostridium difficile is the number one cause of nosocomial antibiotic-associated diarrhea in developed countries. Historically, pathogenesis was attributed two homologous glucosylating toxins, toxin-A (TcdA) and toxin-B (TcdB). Over the past decade, however, highly virulent epidemic strains of C. difficile (B1/NAP1/027) have emerged and are linked to an increase in morbidity and mortality. Increased virulence is attributed to multiple factors including: increased production of A- and B-toxins; production of binary toxin (CDT); and the emergence of more toxic TcdB variants (TcdB(027))...

Bovine viral diarrhea virus (BVDV) is a rapidly evolving, single-stranded RNA virus and a production limiting pathogen of cattle worldwide. 79 viral isolates collected between 1997 and 2013 in Canada were subjected to next-generation sequencing. Bayesian phylogenetics was used to assess the evolution of this virus. A mean substitution rate of 1.4×10(-3) substitutions/site/year was found across both BVDV1 and BVDV2. Evolutionary rates in the E2 gene were slightly faster than other regions. We also identified population structures below the sub-genotype level that likely have phenotypic implications...

Intestinal capillariasis, a fish-borne nematodiasis, is an important emerging zoonotic disease. Patients present clinical symptoms of borborygmus chronic diarrhea, intermittent abdominal pain, weight loss, and several degrees of painless lower-leg edema. Death may occur in cases of misdiagnosis and improper treatment. Diagnosis is difficult because of the atypical clinical symptoms and diagnostic confusion with diarrhea caused by gastrointestinal cancer, opportunistic infections in human immunodeficiency virus patients, and hyperthyroidism...

Apicomplexan parasites cause a variety of important infectious diseases, including malaria, toxoplasma encephalitis, and severe diarrhea due to Cryptosporidium Most apicomplexans depend on an organelle called the apicoplast which is derived from a red algal endosymbiont. The apicoplast is essential for the parasite as the compartment of fatty acid, heme, and isoprenoid biosynthesis. The majority of the approximate 500 apicoplast proteins are nucleus encoded and have to be imported across the four membranes that surround the apicoplast...

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare malignancies that originate in the gastrointestinal system. GEP-NETs are typically indolent, but tumors known as "functional" secrete hormones that can lead to a complex of symptoms, including flushing, diarrhea, bronchospasm, and valvular heart disease. Management of patients with GEP-NETs requires a multidisciplinary approach, as treatment modalities include surgery, radiology, and pharmacotherapy. The available pharmacologic agents have increased in recently, and now include cytotoxic chemotherapies, somatostatin analogues, multitargeted tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors, and radioisotopic radiotherapies...

In the past decade, Clostridium difficile has emerged as an important gut pathogen. This anaerobic, Gram-positive bacterium is the main cause of infectious nosocomial diarrhea. Whereas much is known about the mechanism through which the C. difficile toxins cause diarrhea, relatively little is known about the dynamics of adhesion and motility, which is mediated by cell surface proteins. This review will discuss the recent advances in our understanding of the sortase-mediated covalent attachment of cell surface (adhesion) proteins to the peptidoglycan layer of C...

Human anaplasmosis (HA) is an emerging tick-borne disease that may present as a mild flu-like illness or a life threatening, sepsis-like condition. Although disease severity is hypothesized to relate to immunopathology and immune dysfunction in humans, studies to directly measure immune responses in infected humans have been very limited. We quantified cytokines in 80 confirmed HA patients using a multiplex chemiluminescence immunoassay system and compared similarly measured responses in 1000 control subjects...
