Microbial flora of the diseased stomach at resection. 1978

G H Bornside, and R Rees, and B B Bornside, and I Cohn

The relation of microbial flora in stomach contents and stomach wall was examined in paired specimens from 10 surgical patients and in specimens of wall from 10 additional patients. The flora of both contents and wall were similar. Paired specimens from five patients contained the same kinds of bacteria. Paired specimens from these patients were sterile. Contents from two patients contained bacteria, but the wall was sterile. Microorganisms isolated were streptococci, lactobacilli, bifidobacteria, bacteroides, staphylococci yeast, and coliforms. Bacterial counts ranged from 0 to 10(7.5) per ml or g in both contents and tissue. Survey of the literature shows that most specimens from patients with gastric ulcers or gastric malignancies are positive for bacteria, while only about 60% of specimens from patients with duodenal ulcers are positive.

UI	MeSH Term	Description	Entries
D007778	Lactobacillus	A genus of gram-positive, microaerophilic, rod-shaped bacteria occurring widely in nature. Its species are also part of the many normal flora of the mouth, intestinal tract, and vagina of many mammals, including humans. Lactobacillus species are homofermentative and ferment a broad spectrum of carbohydrates often host-adapted but do not ferment PENTOSES. Most members were previously assigned to the Lactobacillus delbrueckii group. Pathogenicity from this genus is rare.
D005743	Gastrectomy	Excision of the whole (total gastrectomy) or part (subtotal gastrectomy, partial gastrectomy, gastric resection) of the stomach. (Dorland, 28th ed)	Gastrectomies
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D001419	Bacteria	One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.	Eubacteria
D013270	Stomach	An organ of digestion situated in the left upper quadrant of the abdomen between the termination of the ESOPHAGUS and the beginning of the DUODENUM.	Stomachs
D013272	Stomach Diseases	Pathological processes involving the STOMACH.	Gastric Diseases,Disease, Gastric,Disease, Stomach,Diseases, Gastric,Diseases, Stomach,Gastric Disease,Stomach Disease
D013291	Streptococcus	A genus of gram-positive, coccoid bacteria whose organisms occur in pairs or chains. No endospores are produced. Many species exist as commensals or parasites on man or animals with some being highly pathogenic. A few species are saprophytes and occur in the natural environment.
