Abstract
本發明係關於一種新穎的豬第二型環狀病毒(Porcine Circovirus Type 2, PCV2)株。本發明並關於一種含有該新穎的豬第二型環狀病毒(PCV2)之免疫組合物、一種豬第二型環狀病毒(PCV2)檢測套組,以及該新穎的豬第二型環狀病毒(PCV2)之應用。
Description
本發明係關於動物保健領域,特別是關於一種新穎的豬第二型環狀病毒(PCV2)、含有該病毒之免疫組合物、檢驗套組及應用。
豬環狀病毒(porcine circovirus, PCV)最早是在豬腎細胞株(PK-15, ATCC CCL33)中被發現,雖然會持續感染該細胞,但是並不產生細胞病變效應(cytopathic effect, CPE);另外該病毒雖會感染豬隻,但是並不造成豬隻產生任何病變。該病毒為一環狀單股、全長1759 bp的正二十面體(icosahedron)病毒,在1995年被歸類為環狀病毒科(Circoviridae)的一員。
而1991年首度於加拿大發現的仔豬離乳後多系統耗弱症(Postweaning Multisystemic Wasting Syndrome, 以下簡稱PMWS),主要發病的對象為5到12週齡的保育後期及肥育前期仔豬,其臨床症狀包括漸進性的消瘦、呼吸急促、皮膚蒼白及偶爾可見黃疸等,解剖分析可看到間質性肺炎肉芽腫、肝炎、腎炎及淋巴病變等。自從PMWS在加拿大爆發後,北美、歐洲及亞洲等世界各主要國家幾乎都有報導PMWS的發生。近年,從罹患PMWS的病豬身上被分離出另一種新的環狀病毒,該病毒與當初從PK-15細胞分離出的環狀病毒外形非常相似,但是基因組序列的相似度只有68-76%,後來將無致病性的豬環狀病毒稱為豬第一型環狀病毒(porcine circovirus type 1, PCV1),而會造成PMWS的病毒則稱為豬第二型環狀病毒 (porcine circovirus type 2, PCV2)。
豬第二型環狀病毒(PCV2)屬於環狀病毒科(circoviridae),為不具套膜(envelope)的正二十面體(icosahedron)病毒,直徑約17 nm,病毒核酸為單股環狀DNA,在DNA的環狀基因組上有一莖-環狀(stem-loop)的構造為複製起始點,此為環狀病毒共通的特徵。PCV2的基因組有1768或1767個核苷酸,是目前已知最小的動物病毒。PCV2基因組序列經軟體分析後發現順時針加上逆時針共有11個開放閱讀框架(open reading frame, ORF),其中ORF1、ORF2是2個最主要的基因。ORF1可轉錄出Rep及Rep’蛋白,與該病毒的複製有關。而ORF2則是PCV2的外殼蛋白(capsid),是最有可能誘發出中和抗體的抗原。
PCV2在全世界都有很高的感染率。PCV2會造成豬隻育成率及飼料換肉率的降低,而使得養豬業受到極大的衝擊與經濟損失,所以PCV2檢測/診斷試劑及疫苗的開發,可說是刻不容緩且極為重要的事。

實施例一 豬第二型環狀病毒
(PCV2)
之分離與鑑定
1. 種病毒株來源:
受感染的豬隻肺臟及淋巴結檢體係自一養豬場(台灣,新竹)中採集而來。這些受採樣的八週齡豬隻皆具有仔豬離乳後多系統耗弱症(PMWS)的臨床徵狀。肺臟及淋巴結檢體採集後隨即置於-70°C中保存。
為了分離檢體中的病毒,將已均質化之上述檢體0.2ml接種於未受豬環狀病毒(PCV)、豬瘟病毒(classical swine fever virus, CSFV)、豬腺病毒(porcine adenoviruses)、豬小病毒(porcine parvovirus)、豬繁殖與呼吸綜合症(porcine reproductive and respiratory syndrome virus, PRRSV)、豬偽狂犬病(pseudorabies virus, PRV)、豬水泡病病毒(swine vesicular disease virus, SVDV)、黴漿菌及其他細菌污染的豬腎細胞(PK-15)單層細胞或其衍生(derived)之細胞株進行培養,於37°C、5% CO2作用1小時後,以滅菌PBS沖洗3次,置入含2%胎牛血清之新MEM培養液培養4小時,將培養液倒棄,加入300mM之D-glucosamine作用30分鐘,以PBS沖洗3次後,置入約含8%胎牛血清之新MEM培養液中,於37°C、5% CO2培養箱內培養72小時,再以免疫螢光分析法(IFA)進行檢測有無病毒存在。
免疫螢光分析法(IFA)的步驟如下:樣品來自上述接種後之細胞,首先將培養液去除,以1倍PBS洗三次,每次五分鐘。加入75μl的80%丙酮(以蒸餾水配製),於4°C固定三十分鐘,將丙酮去除後,以1倍PBS洗三次,每次五分鐘。接著將PBS去除,再加入75μl以PBS稀釋1500倍之porcine circovirus anti-viral polyclonal antiserum (VMRDO)(一級抗體),於37°C培養箱中培養三十分鐘後,再將一級抗體移除,以1倍PBS洗三次,每次五分鐘。移除PBS後,加入75μl以PBS稀釋1000倍之Rabbit anti-Pig IgG-FITC (whole molecule) (Sigama, F1638)(二級抗體),於37°C培養箱中培養三十分鐘後,將二級抗體去除後,以1倍PBS洗三次,每次五分鐘。最後於96孔盤中加入200μl的1倍PBS,以螢光顯微鏡觀察螢光。
選出IFA結果最佳者之細胞所感染的病毒為種病毒株。並對該病毒株基因組序列進行定序,定序結果如SEQ ID No: 1所示,經序列比對鑑定確認為新病毒株(病毒株鑑定方法與結果如下所述),將之命名為豬第二型環狀病毒H株(PCV2 H strain)。
2. 種病毒株繼代:
將上述選出之豬第二型環狀病毒H株(PCV2 H strain)感染新鮮的PK-15細胞或其衍生之細胞株,得到的病毒稱之為P1代。收集所培養細胞的上清液(P1代)並將之稀釋(比例為1:2)後,再感染新鮮的PK-15細胞或其衍生之細胞株,培養3天後,收集培養細胞的上清液(含P2代病毒株),再次稀釋(比例為1:2)並感染新鮮的PK-15細胞或其衍生之細胞株,培養3天後收集上清液得到P3代。重複上述步驟3次以上,以取得豬第二型環狀病毒H株(PCV2 H strain) P6代。
以PK-15細胞或其衍生之細胞株培養豬第二型環狀病毒H株(PCV2 H strain)的過程中,觀察到該病毒株會造成宿主PK-15細胞或其衍生之細胞株產生細胞病變效應(cytopathic effect, CPE)的現象,CPE現象如圖一B所示;其中圖一A為未感染豬第二型環狀病毒H株(PCV2 H strain)的PK-15細胞,培養4天後細胞生長的形態(100×);圖一B為感染豬第二型環狀病毒H株(PCV2 H strain)的PK-15細胞,培養4天後細胞生長的形態(100×)。其中PK-15衍生之細胞株的CPE現象亦可參閱圖一B所示。
3. 種病毒株鑑定:
本發明所分離得到的豬第二型環狀病毒H株(PCV2 H strain)的基因組序列如SEQ ID No: 1所示,將SEQ ID No: 1所示序列與美國國家生物技術資訊中心(NCBI)基因資料庫(GenBank)進行比對,結果如表一所示,豬第二型環狀病毒H株(PCV2 H strain)的基因序列與豬第二型環狀病毒(PCV2)相似,相似度可達99%,但並無發現GenBank資料庫中有與豬第二型環狀病毒H株(PCV2 H strain)基因序列完全一樣(相似度100%)的豬第二型環狀病毒(PCV2)存在。因此,由比對結果可知,本發明所得到的病毒分離株係屬豬第二型環狀病毒(PCV2)一員,且為一株新穎的病毒株。經親緣關係樹分析結果如圖二所示,由分析結果可知,豬第二型環狀病毒H株(PCV2 H strain)屬於PCV2 2d亞群(subgroup)的一員。
表一 PCV2 H株基因組序列於NCBI比對之結果
分析結果顯示,本發明之豬第二型環狀病毒H株(PCV2 H strain)具有第一開放閱讀框架(ORF 1),其具有如SEQ ID No: 2所示之序列,其係編碼如SEQ ID No: 3所示之胺基酸序列;第二開放閱讀框架(ORF 2),其具有如SEQ ID No: 4所示之序列,其係編碼如SEQ ID No: 5所示之胺基酸序列;以及第三開放閱讀框架(ORF 3),其具有如SEQ ID No: 6所示之序列,其係編碼如SEQ ID No: 7所示之胺基酸序列。
由於豬第二型環狀病毒(PCV2)的ORF2基因序列編碼的外殼蛋白(capsid),是較有可能誘發出中和抗體的抗原,因此,本案發明人將豬第二型環狀病毒H株(PCV2 H strain)的ORF2 DNA序列(如SEQ ID No: 4所示)及胺基酸序列(如SEQ ID No: 5所示)與NCBI的資料庫(GenBank)進行比對。結果顯示,GenBank資料庫內並無與豬第二型環狀病毒H株(PCV2 H strain)的ORF2 DNA序列或胺基酸序列完全一樣(相似度100%)的序列存在,胺基酸序列相似度最高達98%。將胺基酸序列相似度最高的前三名序列與豬第二型環狀病毒H株(PCV2 H strain)的ORF2胺基酸序列進行比對,結果如圖三所示,比對後發現有6個胺基酸不同。而與豬第二型環狀病毒(PCV2) 2d亞群的原型株(prototype)(GenBank編號:ZJ0955b)的ORF2 (GenBank登錄號:ADD25772)胺基酸序列相比,結果如圖四所示,豬第二型環狀病毒H株(PCV2 H strain)與該序列有7個胺基酸相異,相似度為97%。
此外,本案發明人亦將豬第二型環狀病毒H株(PCV2 H strain)之ORF1以及ORF3的DNA序列(如SEQ ID No: 2及6所示)及胺基酸序列(如SEQ ID No: 3及7所示)序列分別與NCBI的GenBank資料庫進行比對,結果發現GenBank資料庫中亦無與本發明豬第二型環狀病毒H株(PCV2 H strain)之ORF1及ORF3的DNA序列及胺基酸序列完全相同者(相似度100%)。
經上述結果證實,本發明所提供之豬第二型環狀病毒H株(PCV2 H strain)係為一新穎的豬第二型環狀病毒株(PCV2),該病毒株已於中華民國99年7月6日寄存於新竹食品工業發展研究所生物資源保存及研究中心,寄存編號為BCRC 970053。

1. 小鼠免疫試驗
用5~6週齡健康雌性清潔級Balb/c小鼠60隻作為試驗動物,所有小鼠的豬第二型環狀病毒(PCV2)酵素結合免疫吸附分析(ELISA)抗體皆呈陰性。將這60隻小鼠隨機分為4組,每組15隻,第1~3組分別以肌肉注射3個批次的豬第二型環狀病毒H株(PCV2 H strain)不活化疫苗,注射劑量為0.2ml/隻,兩週後用相同免疫劑量加強免疫一次;第4組為空白對照組,隔離飼養觀察,首次免疫後第2、3、4、5週分別隨機取出5隻,採血分離血清,測定血清內豬第二型環狀病毒(PCV2)之ELISA抗體力價。
2. 血清抗體之判定 – 以酵素連結免疫分析(ELISA)測定豬第二型環狀病毒(PCV2)抗體力價
可採用實施例三或實施例四所製備之抗原盤作為檢測套組。以含有500 ml/L Tween-20的50 mmol/L PBS (pH 7.2) (即PBST)洗滌抗原盤3次,每次3~5分鐘;再於抗原盤中加入0.15% BSA阻隔液(blocking solution)(200μL/孔),以阻隔(block)抗原盤,並於37°C下作用2小時後,以PBS洗滌。將待檢測之小鼠血清以PBS緩衝液以1:50倍數稀釋,然後再做倍比稀釋;每孔加100μL稀釋之小鼠血清,於37°C下作用1小時後,以PBS洗滌;然後加入酵素(辣根過氧化酵素 (Horseradish peroxidase, HRP)標定之二級抗體(如:兔抗鼠之二級抗體),於37°C下作用1小時後,以PBS洗滌;接著加入3, 3’, 5, 5’-四甲基聯苯胺二鹽酸(3, 3’, 5, 5’-tetramethylbenzidine, TMB)溶液顯色,最後用2mM的H2SO4終止反應後判定結果。判定結果標準為:血清樣本OD450值/陰性血清OD450值(P/N值) ≥ 2.1為陽性。以P/N值 ≥ 2.1的血清最大稀釋度作為該血清樣本的ELISA抗體力價。
除了本實施例所用之辣根過氧化酵素(HPR)與TMB之外,亦可使用其他具有相同功能之顯色試劑、或螢光標記,如:鹼性磷酸酶(alkaline phosphatase, AP)、4-甲基傘形酮磷酸酯(4-Methylumbelliferyl Phosphate, 4-MUP)、螢光異硫氰酸鹽(Fluorescein isothiocyanate, FITC)。
3. 結果
小鼠經不同批次的疫苗首次免疫後,於首次免疫後第二週起均可從小鼠血清中檢測出抗豬第二型環狀病毒H株(PCV2 H strain)之抗體,再經加強免疫後,其ELISA抗體力價於首次免疫後35天可達1800~2000 (圖五);由此可知,本發明所提供之豬第二型環狀病毒H株(PCV2 H strain)不活化疫苗可有效誘發小鼠體內的免疫反應。

2. 血清抗體之判定 –免疫螢光分析法(IFA)法測定豬第二型環狀病毒(PCV2)抗體力價
將實施例三製得之豬第二型環狀病毒(PCV2)抗原盤由-20°C低溫保存環境取出之後,倒置放進37°C培養箱中風乾。將收集的豬隻血清樣本先以 PBS buffer進行50倍稀釋,然後連續以2倍稀釋的方式進行稀釋,再將稀釋之血清樣品分注於豬第二型環狀病毒(PCV2)抗原盤中,每孔分注50 μl。再將抗原盤置於37°C培養30分鐘後以PBS清洗3次,以去除未作用之抗體,每孔再加入50 μl rabbit-anti-pig IgG FITC conjugate (1:100, Sigma),避光培養30分鐘後以PBS清洗3次,於螢光顯微鏡下觀察,並進行豬第二型環狀病毒(PCV2)抗體力價判定。(Rodriguez-Arriojaet al., 2000)
3. 結果
3.1 抗體力價
請參閱表四及圖六所示,仔豬經不同批次的疫苗首次免疫後,於首次免疫後第二週(5週齡)時,其抗體力價已升至約600,而對照組則無變化。再經二次免疫(6週齡)後,發現免疫組之抗體力價皆大幅度提升;於8週齡時,其抗體力價亦較6週齡時更為提升,而對照組仍無變化。

1. 豬體免疫試驗
取14~16日齡豬第二型環狀病毒(PCV2)抗體呈陰性的健康仔豬20頭,隨機分為4組,每組5頭。第1~3組分別以肌肉注射3個批次的豬第二型環狀病毒H株(PCV2 H strain)不活化疫苗,注射劑量為1ml/頭,兩週後用相同免疫劑量加強免疫一次;第4組為空白對照組,隔離飼養;首次免疫後第5週以第二型環狀病毒H株(PCV2 H strain)(強毒株)(106.0TCID50/ml)攻毒,每頭豬滴鼻1ml、肌肉注射2ml,攻毒後第7、11、19和25天採集血清和鼻拭之樣品,以PCR檢測有無病毒。
2. 以PCR偵測豬第二型環狀病毒(PCV2)(病毒血症)
以聚合酶連鎖反應(PCR)檢測豬隻血液樣本內豬第二型環狀病毒(PCV2)。病毒DNA的萃取用DNAzolR試劑,基本步驟為:於200μL血清中加入400μL DNAzol,以12,000 rpm/min離心15min後取上清,並加入2倍體積的無水乙醇沉澱,再以12,000 rpm/min離心15min後棄掉上清液,以75%乙醇洗滌DNA,再以12,000 rpm/min離心5min後棄掉上清液,最後以8mM NaOH溶DNA。
檢測豬隻血液樣本內豬第二型環狀病毒(PCV2)所用的引子序列如下: PCV2-F1: 5’ GTGAAGTGGTATTTTGGTGCC 3’ (SEQ ID No: 8) PCV2-R1: 5’ GTCTTCCAATCACGCTTCTGC 3’ (SEQ ID No: 9) 預期擴增片段在PCV2 ORF1區域,增幅的PCR產物大小為284bp。PCR反應總體積為25μL,含正向引子PCV2-F1 1μL、反向引子PCV2-R1 1μL、25mM Mg2+1.5μL、2.5 mM dNTPs 2.0μL、10×Mg2+free buffer 2.5μL、Taq DNA聚合酶0.2μL、二次蒸餾水11.8μL,以及模板DNA 5μL。PCR反應條件為:95°C反應5分鐘後,進行94°C 30秒、55°C 30秒、72°C 30秒,共38個循環,再以72°C反應5分鐘以進行延伸反應,最後則維持在4°C。PCR產物以1%瓊脂糖凝膠電泳分析。
另,用以檢測豬隻血液樣本內豬第二型環狀病毒(PCV2)之引子序列亦可為: PCV2-F2: 5’ TGTTGGCGAGGAGGGTAATG ’3 (SEQ ID No: 10) PCV2-R2: 5’ TGGGACAGCAGTTGAGGAGT ’3 (SEQ ID No: 11) 利用該引子對可增幅的PCR產物大小為676bp。
3. 病理解剖和病理組織學觀察
豬隻於攻毒後第25天宰殺解剖,以觀察臟器病理變化,並採集淋巴結和肺臟組織,以4%甲醛固定,製備石蠟切片,進行甦木精-伊紅染色(hematoxylin-eosin staining),顯微鏡觀察組織病變。
4. 結果
4.1病毒血症
從PCR檢測病毒血症之結果可知,在攻毒後25天時,免疫組(第1組、第2組、第3組)的病毒血症發生率比未免疫之對照組(第4組)的病毒血症發生率低40~60% (表六),表示本發明之豬第二型環狀病毒H株(PCV2 H strain)不活化疫苗可誘發豬隻產生免疫力、降低病毒血症之嚴重性、縮短病毒血症之感染時間,進而提供豬隻足夠之保護效果以抗豬第二型環狀病毒(PCV2)之感染。

4.2 病理變化
請參閱表七,豬隻攻毒後第25天宰殺解剖,進行病理學觀察,結果顯示:攻毒對照組中2隻仔豬的腹股溝淋巴結、肺門淋巴結和腸系膜淋巴結明顯水腫、切面蒼白,1隻仔豬的肺臟彈性變小、水腫,或腎臟變黃,有少量灰白色點;而免疫組仔豬則皆沒有明顯的病理變化。
表七、豬攻毒後的肉眼病理變化觀察統計結果
a. 分母為剖解豬總頭數,分子為有病變豬頭數; b. 肉眼病理變化:淋巴結水腫,切面蒼白;肺臟水腫、彈性變小,或輕度實變;花斑腎指腎臟變黃,有少量灰白色點;其它病變包括肝膽輕度腫大,腸道鼓氣。
表八係為不同試驗豬隻經攻毒後,其病理變化及豬第二型環狀病毒(PCV2)檢測結果,結果顯示:攻毒對照組中各豬隻之病理變化明顯,如:淋巴結內淋巴細胞缺失(5/5)、巨噬細胞浸潤(4/5)、淋巴結中豬第二型環狀病毒(PCV2) PCR檢測結果均為陽性(5/5);3隻仔豬的肺臟組織有單核細胞浸潤、肺組織中豬第二型環狀病毒(PCV2) PCR檢測結果有2隻仔豬呈陽性;而3個免疫組中只有1隻仔豬的淋巴結出現組織病理變化,淋巴結和肺組織中 豬第二型環狀病毒(PCV2) PCR檢測結果呈陽性(如表八所示)。因此,該三批次的豬第二型環狀病毒H株(PCV2 H strain)滅活疫苗對於豬隻均有明顯保護作用,其保護率約為80%~100%。
表八、不同試驗豬隻經攻毒後,其病理變化及PCV2檢測結果
