有關犬心絲蟲的問題,希望專業人士回答 (請簡答,勿貼網頁)

1.生活史?

2.宿主?

3.傳染途徑?

4.病人感染後的臨床表徵?

5.如何診斷? (人,不是狗哦)

Update:

請問micky:

1.那它是否有最終宿主呢?

2.感染人類的機率有多高呢?

感謝!

Update 2:

請問micky:

1.就病史而言,病人在感染犬心絲蟲之後會有什麼樣的症狀表現呢? (如:咳嗽、胸痛、咳血等…)

感謝…

Update 3:

請問micky:

若用犬心絲蟲抗原測試,測得血清抗體陽性,是否就能診斷犬心絲蟲症呢?

Update 4:

請問micky:

dead-end host指的是什麼宿主?

那狗為其最終宿主,其餘(如:貓)是中間宿主嗎?

Update 5:

請問micky:

我的問題是被人該蚊叮咬之後,發病的機率高不高?

抱歉問題好像有點,不過您答的都還不錯

真是專業啊,感謝!!!

Update 6:

請問micky:

血液抹片看到微絲蟲的機率高嗎,而需要在特定的時間嗎 (如:晚上)?

Update 7:

可以給我你找到資料的網頁嗎? (micky)

感激不盡!!!

    1.生活史

    圖片參考:http://www.stopworms.com/img/hw_lifecycle.jpg

    2. 宿主:    狗 貓 狼 狐狸 雪貂 海獅 土狼    dead-end host: 人 浣熊 熊 海狸3.傳染途徑:   藉由蚊子吸血而傳播4.the heartworm dies shortly after arriving in the human lung, and a nodule, known as a granuloma, forms around the dead worm as it is being killed and absorbed. If an infected person happens to have a chest X-ray at that time, the granuloma may resemble lung cancer on the X-ray and require a biopsy to rule out the life threatening condition. This may well be the most significant medical consequence of human infection by the dog heartworm.5 如4所說 人可由照超音波或x-ray或切片診斷

    1.就是狗那一行裡寫的,是它的自然宿主2.感染人的機率? 這個問題我有點不太懂..看蚊子高興吧XD 還是你是想問在人的流行率?我查到歐洲的Italy is the European country with the highest prevalence of human dirofilariasis (66%), followed by France (22%), Greece (8%), and Spain (4%).

    症狀Most patients are asymptomatic (approximately 56-62% of cases).Symptoms of HPD, when present, include localized retrosternal chest pain, cough, hemoptysis, wheezing, low-grade fever, chills, and malaise.One patient also reported loss of consciousness following chest pain.

    2006-05-14 19:04:02 補充:

    Another patient experienced acute bilateral knee pain and swelling with fever.Aberrant cutaneous sites may be involved (eg, conjunctiva), and the most common symptom is eye pain.

    dead end host-是說,這個環境不適合此虫生長, 所以它無法在這個宿主內"長大", 完成一整個life cycle, 所以就算某人得了心絲虫, 蚊子咬了這個人再去咬下一個人, 下一個人也不會被傳染..也就是這隻虫到了"人"身上, 就無法再傳給下一個宿主..故叫"dead end host"

    人得到後大部分沒症狀(在"症狀"的下一行有寫)~~:)你提到的血清抗體陽性, 我想這個方法應該是滿準確的,不過應該是還要配上其它的診斷方法, 如臨床症狀血液抹片等等來確診~

    差不多是從這兩個來的~~~~

    還有一些是忘記從哪來

    其實google超多的

    用dirofilaria搜尋!!
