Bir MSPP düzeni kurulması en kritik adım biyomarkır iyon kimliklerin kesin genetik belirlenmesidir. Hiç şüphesiz bir biyobelirteç tanımlamak mümkün değilse, o zaman düzeni 13 uzak tutulmalıdır. C. jejuni ssp. doylei Şema 14 farklı biyomarker iyonları içerir. Bu 5 daha C&#39;ye göre olan saptanabilir C arasında jejuni ssp. jejuni MSPP şeması 13 hayranlarıyla en önemli fark jejuni ssp....

Son on yılda, matris destekli lazer desorpsiyon iyonizasyon time-of-flight kütle spektrometresi (MALDI-TOF MS) klinik mikrobiyoloji 1, 2 mikrobiyal cins ve türlerin tanımlanması için son derece değerli standart yöntem olarak ilerlemiştir. Türlere tanımlama sağlam hücreler veya hücre lizatları küçük protein parmak izi kayıt dayanır. Rutin klinik mikrobiyoloji kullanılan bir kütle spektrometresi için tipik kütle aralığı 2-20 kDa olduğunu. Buna ek olarak, sonuçta elde edilen spektrumlar aşağıda türlere suşları ve aşağıda alttür seviye 3 ayırmak için kullanılabilir. Ilk öncü çalışmalar, Campylobacter jejuni 4 suşları özel bir alt grubunun, Clostridium difficile, 5, Salmonella enterica SSP için özel biyomarker iyonları belirledik. serovar typhimurium 6, Staphylococcus aureus 7-9 ve E12 - scherichia 10 coli. alel izoformları karşılık gelen birkaç değişken biyobelirteç kitlelerin kombinasyonu derin alttiplendirmesinde için seçenek sunar. Daha önce, başarılı bir C üzerinde kütle spektrometresi tabanlı phyloproteomics (MSPP) olarak adlandırılan anlamlı ve tekrarlanabilir phyloproteomic ilişkiler içine kitle profilleri bu varyasyonları dönüştürmek için bir yöntem uygulamaya jejuni ssp. jejuni izole koleksiyonu 13. MSPP multilokus sekansı yazarak (MLST) gibi bir DNA dizisi esas alt-tiplemesi tekniklerine kütle spektrometrik eşdeğer kullanılabilir. Campylobacter türlerinin bakteriyel gastroenterit önde gelen nedeni, dünya çapında 14, 15 vardır. Campylobacteriosis enfeksiyon sonrası sekel bir sonucu olarak, yani, Guillain Barre sendromu, reaktif artrit ve iltihaplı bağırsak hastalığı 16 ortaya çıkabilir. Enfeksiyonun başlıca kaynaklarıdırtavuk, hindi, domuz, sığır, koyun ve ördekler, süt ve yüzey suyunun 15, 17 kontamine hayvan eti. Bu nedenle, gıda güvenliği bağlamında düzenli epidemiyolojik sürveyans çalışmalara ihtiyaç vardır. MLST Campylobacter türleri 18 için moleküler yazarak &quot;altın standart&quot; dır. MLST yöntemi göre Sanger sekanslama emek yoğun, zaman alıcı ve nispeten pahalı olduğu için, MLST yazarak nispeten küçük izole kohort sınırlıdır. Bu nedenle, daha ucuz ve daha hızlı alt-tiplemesi yöntemlere ihtiyaç vardır. Bu ihtiyaç MSPP gibi kitle spektrometrik yöntemlerle bir araya olabilir. Bu yazıda Campylobacter jejuni ssp bir koleksiyon kullanarak MSPP-yazmak için ayrıntılı bir protokol sunar. Doylei izolatları ve MLST ile potansiyel karşılaştırılması.

subtyping of campylobacter jejuni ssp. doylei isolates using mass spectrometry-based phyloproteomics (mspp)

-TOF MS tür ve alt türlerinin düzeyinde ama daha aşağıda, gerilme seviyesinde değil sadece bazı bakterileri ayırt etmek imkanı sunuyor. saptanabilir Biyomarker iyonlarının Alelık izoformları izole özgü kitle vardiya sonuçlanır. Kütle spektrometresi tabanlı phyloproteomics (MSPP) referans suşu dizisi bir genomu ile karşılaştırıldığında izole özgü kitle vardiya phyloproteomic ilişkilerin kesinti sağlayan bir düzeni kitle spektrometresi saptanabilir Biyomarker kitleleri birleştiren yeni bir tekniktir. çıkarsanan amino asit dizileri daha sonra MSPP tabanlı dendrogramlar hesaplamak için kullanılır. Burada bir Campylobacter jejuni ssp yazarak MSPP iş akışını açıklar. Yedi suşları izole koleksiyonu doylei. Yedi suşları genetik çeşitlilik ortaya insan kaynaklı ve multilokus dizisi yazarak (MLST) vardı. MSPP yazarak yeterince onların rafi yansıtan yedi farklı MSPP dizisi türlerinde sonuçlandılogenetic ilişkiler. C. jejuni ssp. MSPP Şema 2 ile 11 kDa kütle aralığı 14 farklı biyomarker iyonlarını çoğunlukla ribozomal proteinleri içerir doylei. MSPP ilke olarak, uzun bir seri dizi ile kütle spektrometrik platformlara uyarlanabilir. Bu nedenle, bu teknik zorlanma düzeyi mikrobiyal yazmak için kullanışlı bir araç olma potansiyeline sahiptir.

Daha önce, başarılı C için bir MSPP düzeni kurulmuş jejuni ssp. 13 jejuni. Burada, biz kardeş C alttür yöntemi uzatmak amaçlanmıştır jejuni ssp. doylei. Bu özel ortamda, yedi C. jejuni ssp. doylei izolatları / Laboratuvarı Mikrobiyoloji UGent BCCM / LMG Ghent, Belçika mikroorganizmaların Belçika koleksiyonundan elde edilmiştir. Bizim analizler için kullanılan tüm yedi izolatının i...
