Fungal colonisation by Candida spp. affects a high proportion of VLBW neonates in NICU. However, few data are available on the clinical characteristics of colonisation in preterm infants who are colonised at baseline via vertical transmission, compared to preterms who become colonised during their stay in NICU via horizontal transmission.We reviewed the database of a multicentre, randomised trial of prophylactic fluconazole in VLBW neonates conducted in 8 Italian NICUs in the years 2004 and 2005 (Manzoni et al., NEJM 2007;356(24):2483-95). Per the protocol, all enrolled infants underwent weekly surveillance cultures from birth till discharge. We investigated the frequency of the two different modalities of Candida colonisation in this population, as well as the clinical and outcome characteristics possibly related to them.Overall, Candida colonisation affected 54 of 336 infants (16.1%). Baseline (i.e., detected3(rd) day of life) colonisation affected 16 (4.7%), and acquired 38 (11.4%), of the 54 colonised preterms. Infants with baseline colonisation had significantly higher birth weight (1229 ± 28 g vs. 1047 g ± 29, p = 0.01) and gestational age (30.2 wks ± 2.7 vs. 28.5 wks ± 2.6, p = 0.01), and were significantly more likely to limit progression from colonisation to invasive Candida infection when fluconazole prophylaxis was instituted (21.6% vs. 42.7%, p = 0.009). Isolation of C. parapsilosis was significantly more frequent in infants with acquired colonisation.Infants with baseline and acquired colonisation differ for demographics characteristics and for their response to fluconazole prophylaxis. This information may be useful for targeting more accurate management strategies for these two different groups of colonised preterms in NICU.

s for 2nd International Conference on Clinical Neonatology Comparison of conventional blood culture method and BacT/Alert system with respect to yield and time to positivity in neonatal sepsis Arti Maria⁎, Sumitha Phalgun, Charoo Hans, N. Dubey, Deepak Goyal PGIMER & Associated Dr RML Hospital, New Delhi, India ⁎Corresponding author. Efficient and faster ways of diagnosing neonatal sepsis than conventional blood culture are needed in clinical practice. Recently, automated systems have been developed to address this issue. We hypothesized that automated compared to conventional methods of blood culture may give better isolation performances and shorter time to yield in the diagnosis of neonatal sepsis. This was a single-center, prospective, cohort study enrolling neonates with suspected neonatal sepsis in tertiary neonatal referral unit of north India. From May 2008 to April 2009, ninety consecutive neonates with suspected sepsis were enrolled with the objective of comparing the sensitivity and the time needed to yield positivity of conventional vs. BacT/Alert blood culture. Conventional and automated cultureswere collected in standardized manner from each baby, the order being alternate in consecutive babies. Refusal to consent, being ELBW and showing hemodynamical unstability were the only exclusion criteria for the neonates screened for inclusion in the study. Statistical analysis was conducted with the SPSS software version 11.0. The results showed that positivity by BacT/Alert was 38.8% (35/90) compared to 14.4% (13/90)with conventionalmethod (p
