Nasal Carriage of Methicillin-Resistant Coagulase Negative Staphylococci (MR-CoNS) Among Veterinarians and Veterinary Students

Abstract

The aim of this work was to determine the nasal carriage of methicillin resistant coagulase negative staphylococci (MR-CoNS) among veterinarians and veterinary students. In addition, species distribution, antimicrobial susceptibility, resistance genes and staphylococcal chromosomal cassette mec (SCCmec) type of the isolates were also investigated. MR-CoNS were isolated from 43.8% (39/89) of veterinarians and 44.6% (37/83) of students. While all MR-CoNS isolates were susceptible to quinopristin-dalfopristine, 64.5% of the isolates showed multi-resistance. MR-CoNS strains carried single or various combinations of resistance genes. SCCmec type IV and V were the most common in MR-CoNS strains from both veterinarians and students. This study shows that the rate of nasal carriage of multi-resistant MR-CoNS carriage among veterinarians and veterinary students is high.

Veteriner Hekim ve Veteriner Fakültesi Öğrencilerinde Nazal Metisilin Dirençli Stafilokok (MD-KNS) Taşıyıcılığı

Abstract

Bu çalışmada veteriner hekimler (n=89) ve veteriner fakültesi öğrencileri (n=83) arasında nazal metisilin dirençli koagulaz negatif stafilokok (MD-KNS) taşıyıcılığının saptanması amaçlandı. Ayrıca, izolatların tür dağılımı, antimikrobiyal duyarlılıkları, antibiyotik direnç genleri ve stafilokokal kaset kromozom mec (SCCmec) tipleri de araştırıldı. MD-KNS veteriner hekimlerin %43,8’inden (38/89) ve öğrencilerin %44,6’sından (37/83) izole edildi. MD-KNS suşlarının tamamı kinopristin-dalfopristine duyarlı bulunurken; izolatların %64,5’ı çoğul dirençlilik gösterdi. MD-KNS suşları direnç genlerinin tek veya farklı kombinasyonlarını taşıdı. Hem veteriner hekimlerden hem de öğrencilerden izole edilen MD-KNS suşlarında SCCmec tip IV ve V en yaygın tipler olarak belirlendi. Bu çalışma, veteriner hekimler ve veteriner fakültesi öğrenciler arasında nazal çoğul dirençli MD-KNS taşıyıcılık oranının yüksek olduğunu göstermektedir.
