Co-existence of Sarcina Organisms and Helicobacter pylori Gastritis/Duodenitis in Pediatric Siblings

Sarcinaventriculi (S. ventriculi) are gram-positive, obligate anaerobic bacteria first documented in the human gastrointestinal tract in 1842 [1-4]. Latin for “package” or “bundle,”Sarcinacocci undergo fission in three planes, perpendicular to one another, resulting in theircharacteristicpacketed morphology, often in tetrads but occasionally in cubes of eight [3,5,6]. In addition, S. ventriculi has a thick (150 to 200 nm) fibrous layer on the outer surface of its cell wall composed mostly of cellulose [1,3]. Given these unique conjoining features—tetrad packets with a thick cellulose-dominant wall—it is not surprising that these organisms were initially thought to be vegetable matter [3].
