OBJECTIVE Reverse cholesterol transport (RCT) involves the removal of cholesterol from peripheral tissue for excretion in the feces. Here, we determined whether red blood cells (RBCs) can contribute to RCT. METHODS AND RESULTS We performed a series of studies in apolipoprotein AI-deficient mice where the high-density lipoprotein-mediated pathway of RCT is greatly diminished. RBCs carried a hi...
BACKGROUND Current screening tests for Rhodococcus equi pneumonia in foals lack adequate accuracy for clinical use. Real-time, quantitative PCR (qPCR) for virulent R. equi in feces has not been systematically evaluated as a screening test. OBJECTIVE The objective of this study was to evaluate the accuracy of qPCR for vapA in serially collected fecal samples as a screening test for R. equi pne...
An Evaluation of Antimicrobial Resistance and Virulence Potential Escherichia coli Obtained from Feces Ornamental Birds in Guilan, Iran
Natural steroids from rat and human feces were fractionated by sequential thin-layer chromatography (TLC) on Florisil, silica gel, and silver nitrate-impregnated silica gel and analyzed by gas--liquid chromatography (GLC). Cholesterol, coprostanol, and coprostanone accounted for more than 95% of the endogenous neutral steroid in human feces, the remainder being predominantly cholestanol. In add...
This study geospatially quantifies the mass of an essential fertilizer element, phosphorus, available from human urine and feces, globally, regionally, and by specific country. The analysis is performed over two population scenarios (2009 and 2050). This important material flow is related to the presence of improved sanitation facilities and also considers the global trend of urbanization. Resu...
Human breast milk is recognized as one of multiple important sources of commensal bacteria for infant gut. Previous studies searched for the bacterial strains shared between breast milk and infant feces by isolating bacteria and performing strain-level bacterial genotyping, but only limited number of milk bacteria were identified to colonize infant gut, including bacteria from Bifidobacterium, ...
Volatile organic compounds from feces and their potential for diagnosis of gastrointestinal disease.
Little is known about the volatile organic compounds (VOCs) in feces and their potential health consequences. Patients and healthcare professionals have observed that feces often smell abnormal during gastrointestinal disease. The aim of this work was to define the volatiles emitted from the feces of healthy donors and patients with gastrointestinal disease. Our hypotheses were that i) VOCs wou...
Five assemblages of Giardia duodenalis were identified from cysts in cattle, dog, cat, sheep, and reindeer feces using ribosomal DNA (rDNA) sequencing. Assemblage A was present in cattle and reindeer feces, Assemblages C and D were present in dog feces, Assemblage E was present in cattle and sheep feces, and Assemblage F was present in cat feces. Giardia virus, originally referred to as Giardia...
Sample preservation and recovery of intact DNA from gut samples may affect the inferred gut microbiota composition in pigs. This study aimed to evaluate the effect of the freezing process and storage temperature prior to DNA extraction on DNA recovery and bacterial community composition in pig feces using quantitative PCR. Fresh fecal samples from six growing pigs were collected and five aliquo...
The near-complete genomes of two picobirnaviruses (PBVs) in diarrheal stool samples, human picobirnaviruses D and E (HuPBV-D and -E), were genetically characterized. Their RNA-dependent RNA polymerase (RdRp) protein sequences had <66% identities to known PBVs. Due to a single nucleotide insertion, the open reading frame 2 (ORF2) in segment 1 of HuPBV-D was interrupted by a stop codon. A small s...
