假單胞菌屬（學名：Pseudomonas）是一類需氧的革蘭氏陰性細菌，它位於假單胞菌科下，已知物種有191個。該屬微生物具有極其豐富的代謝多樣性，這些多樣性也使得它們能夠在非常廣闊的生態位中生存。[1]假單胞菌屬的微生物在in vitro條件下很容易培養，這使得該屬成為科研的絕佳材料，比較典型的研究對象有人類致病菌綠膿桿菌、植物致病菌丁香假單胞菌、土壤細菌戀臭假單胞菌以及能促進植物生長的熒光假單胞菌。

因為廣泛存在於水體和諸如雙子葉植物等的種子中，假單胞菌屬算是較早發現的一種微生物。假單胞菌屬這個名字最早在1894和1900年由Walter Migula給出，當時只是一個很模糊的名詞，它的意思是指「革蘭氏陰性菌，杆狀以及一端有鞭毛的、能夠形成芽孢的細菌」。[2][3]但是後來這些被認為芽孢的東西被證明只是某些儲存物質的顆粒而已。[4]現在我們已經不用這些比較模糊的描述了，而選用綠膿桿菌作為模式種來研究。[4]
和大部分細菌屬一樣，假單胞菌屬的最後共同祖先生活於大約幾億年前。它最早在19世紀末由Walter Migula定名，但它名字的來源在當時並未給出，而是最早見於第七版的細菌命名法著作《伯傑氏系統細菌學手冊》(Bergey's Manual of Systematic Microbacteriology)：pseudo來源於希臘語的pseudes(ψευδής)，即「假」之義；-monas來源於μονάς/μονάδος，為「單個單元」之義；合起來可以把這個名字理解為「假的單元」之義。但是這個名字沒有任何有價值的含義，它並不是說這種生物可能錯誤地會出現單個細胞的狀態，因為它從來就沒有以多細胞的形式存在過。一種比較可靠的猜測是，Migula這樣起名可能單純是想說這種生物是假的「Monas」，Monas是指金藻綱的一種有着微小鞭毛的原生生物。[4]不久之後，其他符合Migula這一模糊定義的微生物也陸續被發現並被加入到這一屬下，但是它們當中的很多在後來通過檢測保守性大分子等方法又被重新劃分到其他門類下了。[5]
最近，利用16S rRNA測序分析手段，很多細菌都被重新劃分分類。[6]有一些原來屬於單胞菌屬和黃色單胞菌屬的細菌又被劃分到了假單胞菌屬下。[7]原來屬於假單胞菌屬的一些菌株現在被分到了伯克氏菌屬和羅爾斯通氏菌屬。[8][9]
2000年，人們獲得了假單胞菌屬某物種的全基因組序列，其後很多其他菌株的序列也被測出，包括：P. aeruginosa strains PAO1 (2000), P. putida KT2440 (2002), P. protegens Pf-5 (2005), P. syringae pathovar tomato DC3000 (2003), P. syringae pathovar syringae B728a (2005), P. syringae pathovar phaseolica 1448A (2005), P. fluorescens Pf0-1, and P. entomophila L48。[5]

假單胞菌屬的總體特徵如下：[53]
假單胞菌屬的其他特徵還有（部分種例外）在鐵限制條件下分泌一種熒光鐵載體。[54]有些假單胞菌屬物種還可以分泌其他類型的鐵載體，如綠膿桿菌可以分泌綠膿桿菌毒素[55]，熒光假單胞菌可以分泌一種叫做thioquinolobactin的含硫鐵載體。[56]假單胞菌屬細菌氧化酶測試呈陽性，這也是其一個典型特徵。
假單胞菌屬可能是雲中形成冰晶的最重要的成核劑，它們在全世界的雨雪形成過程中都起着十分重要的作用。[57]
人們以前認為，假單胞菌屬中所有的種都屬於專性需氧微生物。近來人們在假單胞菌形成的生物膜中發現了例外。[58]在生物膜形成過程中，許多細胞都能夠產生諸如藻朊酸鹽等胞外多糖，這些多糖可以防止假單胞菌被白細胞吞噬。[59]胞外多糖還可以使假單胞菌在食物表面形成一片片難以去除的生物膜。腐壞食物表面的假單胞菌還會使食物聞起來有水果般的味道。
因為是革蘭氏陰性細菌，大部分假單胞菌對青黴素以及很多相關β-內酰胺類抗生素都有抗性，但也有部分對哌拉西林、亞胺培南、替卡西林以及環丙沙星敏感。[59]臨床治療上的其他選擇是諸如妥布黴素、慶大黴素以及阿米卡星等氨基糖苷類抗生素。
因為擁有含有孔蛋白的堅硬細胞壁，假單胞菌能夠在嚴苛的環境下生存。它們的外排泵能夠在許多抗生素發揮作用之前就把它們排出去。
綠膿桿菌是一種機會致病菌，對抗生素表現出低敏感性，較為棘手。[60]一是因為綠膿桿菌細胞壁滲透性低，二是因為其抗生素抗性基因（如mexAB-oprM、mexXY[61]）可調控多種藥物外排泵協同運作。 除了內生抗性，綠膿桿菌還很容易通過基因組突變或水平基因轉移來產生新的抗性。若要獲得對多種藥物的抗性，就需要發生不同的突變或者接受多個水平基因的轉移。高頻突變傾向於在綠膿桿菌中產生能夠引起慢性感染的抗生素抗性，而在內含子中同時出現多個抗生素抗性基因會使菌株同時具有多種抗性。有些研究發現，有些表型抗性會隨生物膜形成或小的變種菌落而出現。[5]
雖然鎵元素沒有什麼自然的生物學功能，但它能對細胞過程產生類似於三價鐵的影響。當細菌錯誤地將鎵當成鐵吸收後，鎵並不像鐵那樣能夠傳遞電子，這會影響細胞呼吸，最終導致細胞死亡。[62][63]
在二十世紀初，依靠經典分類方法來描述和鑑定這一微生物屬經歷了一段頗為坎坷的過程。當人們將比對核糖體RNA的大分子組分作為一項評判標準引入後，假單胞菌的分類就豁然開朗了：根據核糖體RNA的相似性，假單胞菌屬可以分為五個核糖體RNA同源組。在Migula命名假單胞菌屬數十年後，被劃歸到該屬下的微生物種數目達到了驚人的比例。目前該屬的微生物種類已經縮減到了不到原來的10%，這其中有不少菌是新命名的，而原來屬於假單胞菌屬的微生物，其實已經沒有幾個目前還在該屬下了。依賴除核糖體RNA外的其他保守大分子的分類方法使得我們能夠控制該屬不至於過於龐大。[5]
致病菌包括綠膿桿菌、棲稻假單胞菌棲稻假單胞菌、和變形假單胞菌。綠膿桿菌是醫院裏一個較為頭疼的問題，因為它對病人來說是侵染力排第二位的致病菌（院內感染）[來源請求]。它的致病機理可能和綠膿桿菌分泌的蛋白質有一定關係。該細菌具有種類非常廣泛的分泌系統，它們分泌的許多蛋白質都和臨床株的致病性有關。[64]
丁香假單胞菌是一類植物致病菌。它具有五十多種致病變種，其中許多具有高度的宿主專一性。假單胞菌屬的許多其他物種也能成為植物致病菌，但是丁香假單胞菌是研究最為透徹的一個。
儘管並非嚴格的植物病原體，托拉斯假單胞菌在農業上也是一個頭疼的問題，它可以造成栽培蘑菇的細菌性斑點病。[65]能夠造成栽培蘑菇疾病的還有傘菌假單胞菌。[66]
二十世紀八十年代中期始，假單胞菌屬中的某些物種就開始被用來抑制作物致病菌的生長或定殖。這種應用通常稱作生物防治。熒光假單胞菌和Pseudomonas protegens的菌株（如CHAO或Pf-5）的生物防治特性是目前研究最為透徹的，儘管人們目前還不十分清楚熒光假單胞菌促進植物生長的過程是如何實現的。這其中可能的方式有：假單胞菌促進了宿主植物的系統抗性，使得植物能夠更好地抵抗病原體；打敗其他的土壤（致病）微生物（如分泌鐵載體來獲取鐵元素）；產生對其他土壤微生物有害的化合物，如吩嗪類抗體或氰化氫。上述所有方式均已得到了實驗證實。[67]
其他具有生物防治功能的假單胞菌還有：綠葉假單胞菌，產生吩嗪類抗生素抑制特定真菌病原體生長[68]；桔黃假單胞菌產生一種一直格蘭仕陽性細菌的抗生素類物質di-2,4-diacetylfluoroglucylmethane。[69]
假單胞菌屬的某些物種能夠代謝環境污染物，它們可以用來進行生物修復。相關物種包括：
因為具有多種多樣的代謝特徵，能夠在低溫和特殊環境下生存，很多假單胞菌都能夠導致食物腐敗。典型的例子有：莓實假單胞菌可以引起奶製品腐壞,[78]，腐臭假單胞菌和霉味假單胞菌能夠造成雞蛋腐臭，[79]隆德假單胞菌，能夠造成牛奶、奶酪、肉類和魚類的腐敗。[80]
最近，人們已經通過16s核糖體RNA測序將許多以前曾經屬於假單胞菌屬的微生物進行了重新分類。[6]這些被移出假單胞菌屬的物種如下所示；點擊相應物種原名會出現它們目前的新名字：
