Abstract

In this study, 31 Klebsiella pneumoniae strains obtained from 20 premature newboms were examined for their biochemical properties, siderophore production, siderophore types, resistance to serum and plasmid profiles. It was found that all strains utilized citrate and acetate, but not starch; methyl red reaction was negative in all of the strains whereas fermentation of maltose, lactose and dulcitole was variable. Seventeen (54.8%) of the strains were resistant to KCN, 14 (45.1%) sensitive; nine (29%) strains were resistant to serum, 22 (70.9%) sensitive. All strains produced sidereophore. It was found that 12 of the 18 (66.6%) strains isolated from rectal swabs and nine (65.2%) of 13 strains isolated from nasal swabs carried plasmids of various sizes.

Özet

Bu çalışmada, 20 prematüre yenidoğandan izole edilen 31 Klebsiella pneumoniae susu biyokimyasal özellikleri, siderofor üretimi varlığı ve siderofor tipleri, seruma dirençlilik ve plazmit profil özellikleri açısından incelenmiştir. Suşların tümünün sitratı ve asetatı kullandığı, ancak hiçbirinin nişastaya etkili olmadığı ve tümünde metil kırmızısı reaksiyonunun negatif olduğu belirlenirken; maltoza, laktoza ve dulsitole etki değişken bulunmuştur. Suşlardan 17 tanesi (%54.8) potasyum siyanüre dirençli, 14 tanesi (%45.1) potasyum siyanüre duyarlı, dokuz tanesi (%29.0) seruma dirençli, 22 tanesi (%70.9) seruma duyarlı olarak belirlenirken incelenen suşların tümünün siderofor ürettiği saptanmıştır. Rektal sürüntülerden izole edilen 18 sustan 12'sinin (%66.6), burun sürüntülerinden izole edilen 13 suştan dokuzunun (%69.2) çeşitli boyutlarda plazmit taşıdığı saptanmıştır.
