First time isolation of Pseudomonas argentinensis from human skin infection

Abstract

This reported the first isolation of Pseudomonas argentinensis from a human infection, since the discovery of P. argentinensis in 2005. A Palestinian 63-year male practicing gardening on sunny days with exposed arms and legs had experienced recurrent skin infections of forearms and legs. The skin infection progressed from small itchy red rash into fluid-filled vesicles within three days. One type of bacteria was recovered from culture samples of these vesicles. The infection was treated successfully with 2% fucidine. Using the Universal Method, the isolate (labeled as QUBC88) was identified as Pseudomonas argentinensis. The patient\'s son had suffered a similar skin infection while gardening in a different continent. The inability of the isolate QUBC88 to grow at 37°C may explain its inability to cause systemic infection. Future skin infections of the patients will be followed up to determine if the infectious agent is the same, related, or not related to P. argentinensis.

First time isolation of Pseudomonas argentinensis from human skin infection

Öz

Bu 2005 yılında Pseudomonas argentinensis’in tanımlanmasından sonra insan kaynaklı tekrarlayan cilt enfeksiyonundan izole edilen ilk P. argentinensis olgusu bildirimidir. Filistinli 63 yaşındaki erkek bir hastada güneşli günlerde bahçede çalışırken ön kollarda ve bacaklarda tekrarlayan cilt enfeksiyonları gelişti. Üç gün içinde, cilt enfeksiyonu küçük kaşıntılı kırmızı raş lezyonlardan içi sıvı dolu veziküllere dönüştü. Bu veziküllerden alınan kültürde bir tip bakteri izole edildi. Bu lezyonlar %2 fusidin ile düzeldi. Üniversal Metot kullanılarak izolat (QUBC88 olarak etiketlendi) Pseudomonas argentinensis olarak belirlendi. Hastanın başka bir kıtada yaşayan oğlunda da bahçede çalışırken benzer cilt lezyonları gelişti. İzolat QUBC88’in 37°C’de üreyememesi sistemik enfeksiyon oluşturmama nedenini açıklayabilir. Hastalarda daha sonra gelişecek cilt enfeksiyonları izole edilecek mikroorganizmanın yanı bakteri ya da P. argentinensis ile bağlantılı olup olmadığını belirlemek üzere takip edilecektir
