Jing Yuan, Wei Guo
This study investigated the mechanisms of resistance of 36 quinolone-resistant Salmonella Typhimurium strains isolated from outpatients with infectious diarrhea in Beijing Tian Tan Hospital between 2013 and 2015. We measured the resistance spectrum of the 36 strains using the broth dilution method. The analysis also investigated Class 1 integrons harboring the β-lactamase gene and mutations in quinolone resistance determining regions. All 36 quinolone-resistant Salmonella Typhimurium strains were shown to be multidrug-resistant and the majority of these strains harbored Class 1 integrons...

OBJECTIVE: Antibiotic therapy is a major risk factor for the development of diarrhea and colitis with varying severity. Often the origin of antibiotic-associated gastrointestinal deterioration remains elusive and no specific infectious agents could be discerned. PATIENTS: We represent three cases of intractable high-volume diarrhea associated with combined antibiotic and steroid therapy in critically ill patients not fitting into established disease entities. Cases presented with severe apoptotic enterocolitis resembling acute intestinal graft-versus-host-disease...

Background and Aims: Alteration in intestinal permeability is the main factor underlying the pathogenesis of many diseases affecting the gut, such as inflammatory bowel disease (IBD). Characterization of molecules targeting the restoration of intestinal barrier integrity is therefore vital for the development of alternative therapies. The yeast Saccharomyces boulardii CNCM I-745 (Sb), used to prevent and treat antibiotic-associated infectious and functional diarrhea, may have a beneficial effect in the treatment of IBD...

OBJECTIVE Large-scale studies evaluating risk factors for Clostridium difficile infection (CDI), a leading cause of infectious diarrhea among patients undergoing stem cell transplantation (SCT), are lacking. We have evaluated risk factors for CDI among both autologous SCT (auto-SCT), and allogeneic SCT (allo-SCT) recipients using the National Inpatient Sample (NIS) database provided by the Healthcare Cost and Utilization Project (HCUP). METHODS We used patient data obtained from the NIS database for all adult patients admitted for auto- and allo-SCTs from January 2001 to December 2010...

Worldwide, Shigellosis is a significant public health issue, associated with nearly one million deaths annually. About half a million cases of Shigella infection are reported annually in the United States. Shigella bacteremia is uncommon and generally seen in children and immunocompromised adults. We present a case of a Shigella sonnei bacteremia with marked hepatic derangement in a 27-year-old previously healthy homosexual male with history of Roux-en-Y gastric bypass, who presented to the emergency room with a 4-day history of loose watery stool, abdominal cramps, nausea and vomiting, and yellow skin of 2-day duration...

Diarrhea is considered as an important cause of morbidity and mortality, even though one of the main reasons of death following diarrhea is initiated by dysentery. In recent years, the consumption of probiotics has been proposed for the treatment of infectious diarrhea. Despite most of the studies on probiotics have focused on acute watery diarrhea, few studies in the field of dysentery have found beneficial effects of probiotics. This study is a randomized double-blind clinical trial. The patients were randomly placed into control and case groups...

Shigellosis is an acute infectious disease characterized as severe bloody diarrhea (dysentery) and is accountable for a significant burden of morbidity and mortality especially in children under the age of 5 years. Antimicrobial therapy is required in the cases of severe dysentery associated with Shigella. However, emergence of multidrug resistant (MDR) strains of Shigella spp. over the last two decades has restricted the use of common therapeutic antimicrobials. In MDR strains, the third-generation cephalosporins have been used for the treatment, but, unfortunately, emerging reports of enzyme mediated β-lactam resistance among Shigella isolates from various parts of the world have greatly compromised the therapy of pediatric dysentery...

The rotavirus-induced diarrhea of human and animal neonates is a major public health concern worldwide. Until recently, no effective therapy is available to specifically inactivate the rotavirion particles within the gut. Passive immunotherapy by oral administration of chicken egg yolk antibody (IgY) has emerged of late as a fresh alternative strategy to control infectious diseases of the alimentary tract and has been applied in the treatment of diarrhea due to rotavirus infection. The purpose of this concise review is to evaluate evidence on the properties and performance of anti-rotavirus immunoglobulin Y (IgY) for prevention and treatment of rotavirus diarrhea in human and animal neonates...

The physical growth of young children in low- and middle-income countries is reduced compared to international standards. The deviations in growth in both weight and height are greatest in the first 2 years of life and this has serious consequences for child mortality, development, adult stature, and health. The determinants of these patterns of growth faltering include intergenerational factors, such as maternal height, short birth interval, and conditions in pregnancy, including maternal underweight and anemia...

BACKGROUND: Ruminants, including sheep and goats (small ruminants), are key agricultural animals in many parts of the world. Infectious diseases, including many viral diseases, are significant problems to efficient production of ruminants. Unfortunately, reagents tailored to viruses of ruminants, and especially small ruminants, are lacking compared to other animals more typically used for biomedical research. OBJECTIVE: The purpose of this study was to determine the permissibility of a stably immortalized, sheep microglial cell line to viruses that are reported to infect ruminants: bovine viral diarrhea virus (BVDV), bovine herpesvirus 1 (BoHV-1), small ruminant lentiviruses (SRLV), and bovine respiratory syncytial virus (BRSV)...

Human rotaviruses (HRVs) are the major cause of acute diarrhea in infants and young children. Here, a real-time reverse transcription polymerase chain reaction assay targeting the rotaviral VP4 gene (VP4-RT-qPCR) was established to evaluate the inactivation of HRV upon chlorine disinfection, based on a previous report that damage to the 1227-2354bp region of the VP4 gene was associated with eliminated HRV infectivity by chlorine. In this study, inactivation of HRV by 0.6mg/L free chlorine was assessed in phosphate buffered saline (PBS; pH 7...

Oral probiotic administration has been advocated for treatment and prevention of a diverse range of disorders. This study was undertaken to evaluate the effect of probiotic supplementation on outcome of pediatric post-burn patients. Forty thermally-injured pediatric patients with total body surface burns between 20-50% and depth between 5-10% were randomized in a prospective, double-blind, controlled clinical trial into two even groups: probiotic group (n=20), who received probiotic preparations, and placebo control group (n=20)...

Gastrointestinal illness (GI) has been associated with heavy rainfall. Storm events and periods of heavy rainfall and runoff can result in increased microbiological contaminants in raw water. Surface water supplies are open to the environment and runoff can directly influence the presence of contaminants. A time-stratified bi-directional case-crossover study design was used to estimate associations of heavy rainfall and hospitalizations for GI. Cases of GI were identified as in-patient hospitalization with a primary diagnosis of infectious disease associated diarrhea [ICD-9 codes: specified gastrointestinal infections 001-009...

Shigella spp. causing bacterial diarrhea and dysentery are human enteroinvasive bacterial pathogens that are orally transmitted through contaminated food and water and cause bacillary dysentery. Although natural Shigella infections are restricted to humans and primates, several smaller animal models are used to analyze individual steps in pathogenesis. No animal model fully duplicates the human response and sustaining the models requires expensive animals, costly maintenance of animal facilities, veterinary services and approved animal protocols...

BACKGROUND: A rapid molecular test for identifying cases of infectious diarrhea might be beneficial for patients. METHODS: We established a LightMix modular multiplex PCR assay for rapid detection of Campylobacter, Salmonella, Yersinia, and Shigella species from fecal samples. RESULTS: Unlike Campylobacter sp., direct detection of Salmonella from feces by multiplex PCR was significantly less sensitive than culture. Only 11 out of 21 (52%) Salmonella culture positive specimens were positive for Salmonella in the direct multiplex PCR assay (Campylobacter: 52/53 samples [98%])...

INTRODUCTION: Vaccination against Salmonella Typhi is one of the leading public health interventions reducing the risk of typhoid fever. There are two available licensed vaccines, Vivotif, oral live-attenuated, and Typhim Vi, intramuscular Vi capsular polysaccharide. The US military is a high risk travel population commonly vaccinated for S. Typhi. We describe the use of S. Typhi vaccination in this population and the acute reactogenicity profile of these vaccines. METHODS: Data were obtained from the Defense Medical Surveillance System and vaccination identified between 1998 and 2011 from vaccination codes...

Clostridium difficile infections are the leading cause of health care-associated infectious diarrhea, posing a significant risk for both medical and surgical patients. Because of the significant morbidity and mortality associated with C difficile infections, knowledge of the epidemiology of C difficile in combination with a high index of suspicion and susceptible patient populations (including surgical, postcolectomy, and inflammatory bowel disease patients) is warranted. C difficile infections present with a wide spectrum of disease, ranging from mild diarrhea to fulminant colitis or small bowel enteritis and recurrent C difficile infections...

Malnutrition affects millions of children in developing countries, compromising immunity and contributing to increased rates of death from infectious diseases. Rotavirus is a major etiological agent of childhood diarrhea in developing countries, where malnutrition is prevalent. However, the interactions between the two and their combined effects on immune and intestinal functions are poorly understood. In this study, we used neonatal gnotobiotic (Gn) pigs transplanted with the fecal microbiota of a healthy 2-month-old infant (HIFM) and fed protein-deficient or -sufficient bovine milk diets...

An 84-year-old man was referred to our hospital because of watery diarrhea. Due to cerebral infarction, he had started treatment with a novel oral anticoagulants (NOAC) 1 month prior to admission. The patient underwent blood tests, enhanced computed tomography, and colonoscopy, which indicated infectious or medicinal colitis. The diarrhea persisted and he developed hypokalemia, so a second colonoscopy was performed, which showed edematous mucosa. Colonic mucosal biopsies showed a thick collagen band in the subepithelial region, and collagenous colitis was diagnosed...

Porcine epidemic diarrhea virus (PEDV) infects the intestine of young pigs, but effective measures for prevention and treatment are lacking. N-Acetylcysteine (NAC) has been shown to reduce endotoxin-induced intestinal dysfunction. This study was conducted with the PEDV-infected neonatal piglet model to determine the effect of NAC supplementation on intestinal function. Thirty-two 7-day-old piglets were randomly allocated to one of four treatments in a 2 × 2 factorial design consisting of two liquid diets (0 or 50 mg/kg BW NAC supplementation) and oral administration of 0 or 10(4...
