Previous studies on the differences in gut microbiota between exclusively breastfed (EBF) and non-EBF infants have provided highly variable results. Here we perform a meta-analysis of seven microbiome studies (1825 stool samples from 684 infants) to compare the gut microbiota of non-EBF and EBF infants across populations. In the first 6 months of life, gut bacterial diversity, microbiota age, relative abundances of Bacteroidetes and Firmicutes, and predicted microbial pathways related to carbohydrate metabolism are consistently higher in non-EBF than in EBF infants, whereas relative abundances of pathways related to lipid metabolism, vitamin metabolism, and detoxification are lower...

OBJECTIVE: To delineate the clinical and genetic characteristics of a girl featuring motor retardation, language retardation and regression, and light persisting diarrhea. METHODS: The patient was clinically examined and tested by tandem mass spectrometry and next generation sequencing. RESULTS: The proband could not stand and walk alone, and had light persisting diarrhea. She manifested language development retardation and regression. Laboratory tests were all normal, but the screening of metabolic disorders for urine and blood showed deficiency of short chain coenzyme A dehydrogenase due to elevated ethylmalonic acid and butyryl carnitine...

Clostridium perfringens type F (formerly enterotoxigenic C. perfringens type A) strains produce an enterotoxin (CPE) to cause acute cases of food poisoning and chronic nonfoodborne human gastrointestinal diseases (NFD), e.g. antibiotic-associated diarrhea (AAD). NFD strains produce NanI sialidase, an extracellular enzyme that releases sialic acids from sialyated host macromolecules. Recent in vitro studies suggested that NanI may contribute to NFD strain intestinal colonization by enhancing their adherence to intestinal cells and promoting their bacterial growth using generated sialic acid as an energy source...

Clostridium difficile infection (CDI) causes nosocomial/antibiotic-associated diarrhea and pseudomembranous colitis, with dramatic incidence/mortality worldwide. C. difficile virulence factors are toxin A and toxin B (TcdB) which cause cytopathic/cytotoxic effects and inflammation. Until now studies were focused on molecular effects of C. difficile toxins (Tcds) on different cells while unexplored aspect is the status/fate of cells that survived their cytotoxicity. Recently we demonstrated that enteric glial cells (EGCs) are susceptible to TcdB cytotoxicity, but several EGCs survived and were irreversibly cell-cycle arrested and metabolically active, suggesting that EGCs could became senescent...

BACKGROUND: Pyosalpinx, which is one of the pelvic inflammatory diseases, is usually observed in young women; it is rarely found in older women. Possible causative agents are thought to be Chlamydia trachomatis and Neisseria gonorrhea in addition to some Enterobacteriaceae. On the other hand, type 2 diabetes is a disease with a lot of complications such as hyperglycemia, inflammation, and immune disorders. Therefore, patients with type 2 diabetes mellitus have an increased susceptibility to infection especially when glycemic control is poor...

Gardner's syndrome (GS) is a rare syndrome with autosomal dominant inheritance, which is characterized by multiple intestinal polyps, dental anomalies, desmoid tumors, and soft tissue tumors. All gastrointestinal symptoms seen in GS are associated with the underlying familial adenomatosis polyposis and abdominal desmoid tumors, with the most common symptoms being anemia, lower gastrointestinal bleeding, abdominal pain, diarrhea, obstruction, and mucous defecation. To our best knowledge, no case of GS that has presented with gastrointestinal perforation and bleeding has ever been reported in the English language medical literature...

Biliary dyskinesia (BD) is a motility disorder of the gallbladder that can result in right upper quadrant (RUQ) pain, nausea, vomiting, and diarrhea. Cholecystectomy is considered the standard of care for BD. Up to 23 per cent of pediatric patients who undergo surgery for BD have persistent symptoms postoperatively. We performed a retrospective review to identify preoperative factors significantly associated with symptom resolution after cholecystectomy. We retrospectively reviewed pediatric patients aged 10-17 years diagnosed with BD who underwent cholecystectomy between 2006 and 2016...

Different health-care management guidelines by the World Health Organization exist to help health workers in resource-limited settings treat patients. However, for children with unclassified fever and no danger signs, management guidelines are less clear and follow-up recommendations differ. Both "universal follow-up" for all children, irrespective of health status, and "conditional follow-up" only for children whose fever persists are recommended in different guidelines. It is unclear how feasible and acceptable these two different guidelines are among community health workers and caregivers of the sick child...

Bovine viral diarrhea virus 1, reclassified as Pestivirus A, causes an economically important cattle disease that is distributed worldwide. Pestivirus A may cause persistent infection in that calves excrete the virus throughout their lives, spreading the infection in the herd. Many persistently infected (PI) calves die in the first 2 years of life from mucosal disease (MD) or secondary infections, probably as a consequence of virus-induced immune depression. Here, high-throughput sequencing (HTS) was applied for evaluation of the total virome in sera of (i) PI calves displaying clinically apparent MD (n = 8); (ii) PI calves with no signs of MD (n = 8); and (iii) control, Pestivirus A-free calves (n = 8)...

A 3-month-old female Maltese puppy was hospitalized with persistent diarrhea in a local veterinary clinic. Blood chemistry and hematology profile were analyzed and fecal smear was examined. Diarrheal stools were examined in a diagnostic laboratory, using multiplex real-time polymerase chain reaction (PCR) against 23 diarrheal pathogens. Sequence analysis was performed using nested PCR amplicon of 18S ribosomal RNA. Coccidian oocysts were identified in the fecal smear. Although multiplex real-time PCR was positive for Cyclospora cayetanensis, the final diagnosis was Cystoisospora ohioensis infection, confirmed by phylogenetic analysis of 18S rRNA...

BACKGROUND: MHC class II deficiency leads to defective CD4+ T-cell function that results from impaired antigen presentation. A genetic disorder in 1 of 4 genes results in this syndrome that is associated with the clinical phenotype of combined immunodeficiency. OBJECTIVE: To describe the clinical, immunological, and molecular characteristics of 10 Egyptian patients from 9 different families having presented with MHC class II deficiency between 2012 and 2017. METHODS: An initial diagnosis based on the combination of clinical features and low HLA-DR expression by flow cytometry was confirmed by genetic analyses...
