Abstract
Background: Microorganisms were detected in four sites like; nose, skin, ear and umbilicus of normal delivery newborns, at birth. All sites revealed a highest incidence of Enterobacter spp., followed by Escherichia coli, while other isolates like ; Klebsiella, Providencia, Aeromonas spp. and Pseudomonas aeruginosa were lower in incidence in all sites. Bacterial isolates from caesarean section delivery newborns from various sites at different intervals after delivery. Our results revealed that Enterobacter spp. showed the highest isolates in all sites during the first 3 days, started to decrease at 7th day after birth, whereas, other isolates were at variable rates in all sites. Objectives: To determine the microorganisms, that acquires various neonatal sites at different intervals after delivery (at birth, 3days and 7days after birth). Methods: Four hundred and twenty four swabs were collected from various sites at different intervals after birth from 62 newborns admitted to Al-Yermouk Teaching Hospital from August 2008-September2009.All isolates were diagnosed according to well known bacteriological and biochemical standard methods. Confirmatory tests were performed by API 20E system. Results: Gram-negative bacteria were isolated from four sites like; nose, skin , ear and umbilicus of 40 normal delivery newborns , at birth ; All sites, revealed a highest incidence of Enterobacter spp. with a range of (54.8 - 86.3%) , followed by E. coli (25.0-48.3%) ,while other isolates(Klebsiella, Providencia, Aeromonas spp. and Pseudomonas aeruginosa) were lower in incidence in all sites. Bacterial isolates from 22 newborns after caesarean section delivery, showed that Enterobacter spp. had high incidence (27.2-70.2%)at birth, which increased to (44.4-84.6%)at 3rd day, started to decrease to (23.5-56.2%) at 7th day after birth. The Klebsiella and Providencia spp. showed an increase rates in all sites during 7 days after birth, followed by E. coli, while other isolates as Aeromonas spp. and Pseudomonas aeruginosa had a variable rates in all sites. Conclusions: Acquisition pattern, as expressed by incidence and frequency was significantly affected by conditions associated to type of delivery. Pseudomonas aeruginosa among the early acquired and appearance in the skin only, related to the postnatal contamination. Key words: Analysis, Microorganisms, Acquired Newborns
