The aerobic and anaerobic intestinal microflora of 60 newborn infants in Addis Ababa was studied. As opposed to earlier published studies from Stockholm, there were no consistent changes of the microflora attributable to antibiotic treatment. The reason why antimicrobial agents caused quantitatively smaller changes of the intestinal microflora in newborn infants in Addis Ababa than in Stockholm is not known, but may be due to antimicrobial inactivation, or marked, continuous ingestion of bacteria. Colonisation by potentially pathogenic gram-negative bacteria was coupled to a low isolation rate of bifidobacterium, but not of lactobacillus. This is consistent with the hypothesis that bifidobacterium might convey some kind of resistance to colonisation by and overgrowth of gram-negative bacteria in newborn infants. Similar results have previously been obtained in Stockholm. In comparison to 45 healthy infants in Stockholm, the Ethiopian infants had more enterococcus and lactobacillus and less staphylococcus and bacteroides during the first 2 weeks of life. After that time, the only difference was more frequent colonisation by lactobacillus in Addis Ababa.

UI MeSH Term Description Entries
D007223 Infant A child between 1 and 23 months of age. Infants
D007231 Infant, Newborn An infant during the first 28 days after birth. Neonate,Newborns,Infants, Newborn,Neonates,Newborn,Newborn Infant,Newborn Infants
D007422 Intestines The section of the alimentary canal from the STOMACH to the ANAL CANAL. It includes the LARGE INTESTINE and SMALL INTESTINE. Intestine
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.
D004755 Enterobacteriaceae A family of gram-negative, facultatively anaerobic, rod-shaped bacteria that do not form endospores. Its organisms are distributed worldwide with some being saprophytes and others being plant and animal parasites. Many species are of considerable economic importance due to their pathogenic effects on agriculture and livestock. Coliform Bacilli,Enterobacteria,Ewingella,Leclercia,Paracolobactrum,Sodalis
D005002 Ethiopia An independent state in eastern Africa. Ethiopia is located in the Horn of Africa and is bordered on the north and northeast by Eritrea, on the east by Djibouti and Somalia, on the south by Kenya, and on the west and southwest by Sudan. Its capital is Addis Ababa. Federal Democratic Republic of Ethiopia
