FORMATION OF OROPHARYNX MICROBIOCENOSIS IN PREMATURE INFANTS WITH LOW AND EXTREMELY LOW BODY MASS AT BIRTH IN CONDITIONS OF A CHILDREN’S HOSPITAL
There has been conducted a bacteriological study of upper air passages secretion in 58 premature children with body weight less than 1 500g on admission and discharge from the Department of Pathologies of Newborns and Premature Children of the Vyzhletsov Arkhangelsk Children's Hospital from October 2009 till June 2011. On admission to the Department, all the children showed poor microfloa of the oropharynx, it was represented by the coccal flora. During the period of hospitalization in the hospital, the oropharynx microecology was formed by obligate representatives, but there was also registered colonization by pathogenic and opportunistic pathogens. The upper air passages microflora formation was affected by the following factors: artificial pulmonary ventilation, type of infant feeding, correction with probiotics and intrauterine contamination. In the premature infants with low and extremely low body mass at birth in conditions of a long-term stay in the hospital, microbiocenosis of the oropharynx mucosa was not formed adequately.
