Fine structure of Sarcina maxima and Sarcina ventriculi.
The fine structure of Sarcina maxima and S. ventriculi was studied by electron and phase-contrast microscopy. The two organisms differ mainly with respect to their cell surface. A thick cellulose layer present on the cell wall of S. ventriculi was not observed on the surface of S. maxima. Carbon replication indicated that the outer surface of S. ventriculi is rough in contour, probably as the r...
متن کاملGastric Sarcina ventriculi: incidental or pathologic?
A 65-year-old Caucasian female with a history of lap-band procedure ten years ago presented with generalized weakness. For the past two weeks, the patient had been fatigued, sleeping 12-20 h a day and having minimal strength for her activities of daily living. For three days she had had dark stools and diarrhea and denied having a history of gastroparesis. She denied tobacco, alcohol, or illici...
متن کاملSarcina ventriculi in blood: the first documented report since 1872
BACKGROUND In 1872, in British Medical Journal (BMJ) Dr. David Ferrier published that Sarcina ventriculi (Goodsir) constantly occurred in the blood of man and the lower animals. His observation was based on bleeding experiments, incubation of blood at 100°F (37.8°C) and later examination. He found "immense numbers of beautifully formed sarcinæ". In the next issue of BMJ Dr. Charlton Bastian exp...
متن کاملStudies on Sarcina ventriculi. III. Localization of cellulose.
Suringar (1866) and Smit (1930) reported that cell packets of Sarcina ventriculi exhibited a positive cellulose reaction (stained red to purple) when suspended in an aqueous solution containing ZnC12, 12, and KI. These workers believed that cellulose was localized in the cell wall. On the other hand, Delaporte (1957) could not obtain this color reaction and reported that examination of S. ventr...
متن کاملSarcina ventriculi as an Unknown Culprit for Esophageal Stricturing
A 65-year-old woman with metastatic breast cancer and a history of Schatzki ring presented with 2 months of progressive dysphagia. Imaging with x-ray fluoroscopy revealed an irregularly short segment stricture at the mid to distal esophagus. Esophagogastroduodenoscopy (EGD) showed a benign-appearing stenosis with a single 7-mm nodule at the gastroesophageal junction and non-bleeding gastric ulc...
