Only two cases of human infection with the anaerobic Gram-negative bacillus Butyricimonas virosa have been previously reported. We describe the case of a 69-year-old man with B. virosa and diverticulitis, further supporting an association of bacteraemia with this pathogen to bowel disease. We also summarize the characteristics of the previously described cases.
INTRODUCTION AND OBJECTIVE: Calcium oxalate stone formation is due to an interaction between environmental and genetic factors. Metabolic studies are undertaken for the study of both of these domains. These frequently involve placing patients on controlled diets. The appropriate length of lead-in time on these diets has not been adequately defined. We undertook this study to address this issue.METHODS: Eleven healthy, non-stone forming adults (5 men, 6 women, mean age 26.9 years) collected daily 24-hour urine collections while consuming a self-selected diet (SS) for 4 days and a controlled, metabolic diet (CM) for 10 consecutive days. The CM diet consisted of 20% protein, 30% fat, and 50% carbohydrate and contained 250 mg oxalate/2500 kcal and I 002 mg calcium/2500 kcal. The CM diet was adjusted to appropriate caloric requirements for each subject. The following urinary analytes were measured and indexed to urinary creatinine excretion: calcium, citrate, magnesium, oxalate, phosphate, potassium, sodium, urea nitrogen, and uric acid.RESULTS: There are statistically significant differences in oxalate, magnesium, potassium, sodium, and urea nitrogen excretion when comparing the SS diet to the CM diet. The coefficients of variability for calcium (p
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
