[QUOTE=歐石南]會
但要大量
用"升"計

你會飲一升口水? [/QUOTE]

但別忘記有 IgA 等, 還有接觸 oral mucose 不會感染, 到胃又有 strong acid...

所以 - infectivity ~0

[QUOTE=Raul]口水除左水仲有咩 [/QUOTE]
mucin, immunoglobulin A, high molecular weight protein, amylase, bicarbonate ion, lysozyme, lactoferrin, potassium ion, calcium ion, phosphate ion, sodium ion

最主要的 component...

[QUOTE=Sol Campbell]我話唔得意思係指正常情況下都唔得姐

點解傷風感冒經口水傳染既機會大過aids咁多呢 [/QUOTE]
HIV 掂 mucosa 不會 infect

順道分清楚先

HIV (Human Immunodeficiency Virus) 係 virus 名
AIDS (Acquired ImmunoDeficiency Syndrome) 係病名

[QUOTE=bobby zamora]...no cell....isn't it.. it is just a liquid which have some salt......lysozome....some lubricating chemicals[/QUOTE]
er...... yea..... or some cells lost from oral mucosa.. the squamous epithelial cells.......

FlyingDonkey

[QUOTE=食脾細路]因為係病毒,因為比病菌少,所以數量也要多
一個細胞最多HIV量比傷風病菌量少好多倍[/QUOTE]
我不會這樣解釋.......

[QUOTE=bobby zamora]ya
lytic vs lysogenic cycle......
thus i am asking..
is  it this difference..make influenza more transmittable by saliva?[/QUOTE]
1. amt of virus for infection of HIV is larger than amt of virus for infection for influenza......

2. saliva has IgA, protein... etc to anti the action of HIV

3. HIV needa be in contact to CD-4 T-helper cells for infection....
