" dengue fever is often mild and self - limiting . recovery from an initial infection caused by one serotype provides lifelong immunity against the serotype only . 初次被其中一种类型病毒感染并痊愈后，身体对该类型的病毒会产生终身免疫力。
" this was the first local case caused by serotype 2 dengue virus . all local cases that could be tested for dengue viruses so far were serotype 1 , " he said 他说：这是首宗属第二型病毒的本地登革热个案，其他至今可证实的本地个案中均属第一型。
A indirect enzyme - linked immunosorbent assay ( elisa ) was developed for detection of four serotypes ( serotype 1 , serotype 2 , serotype 4 and serotype 5 ) antibodies against riemerella anatipestifer ( r . a . ) 经交叉试验、阻断试验、重复性试验等证实建立的elisa重复性好、特异性强。
Immunity is gained against that serotype after recovery from its infection . however , no effective protection is conferred against subsequent infection by the other three serotypes 登革热患者康复后，身体会产生免疫能力，可预防同一血清型病毒的感染，却不会对其他三种血清型病毒有防御能力。
" subsequent infection by another serotype of the dengue virus increases the risk of acquiring the more serious disease , dengue haemorrhagic fever . with proper treatment , most patients can recover 假如其后再被另一类型登革热病毒感染，便有较大机会出现更严重的病情，例如：登革出血热。
Methods : in the dopa liquid medium , c . neoformans of all serotype strains including capsule - deficient strain were incubated and the d value were monitored under various conditions with a bausch and lomb spectronic 20 方法：在含左旋多巴的液体培养液中孵育各种血清型新生隐球菌，分光光度计测定不同条件下液体的d值。
There are four serotypes of dengue virus . patients fully recovered from one particular serotype may contract the disease again if bitten by mosquitoes carrying a different serotype of dengue virus 登革热可由四种不同类型的登革热病毒所引致，曾感染其中一种病毒的康复者，如再被带有其他类型登革热病毒的病媒蚊叮咬，便有机会再次染病。
" any subsequent reinfection by another serotype of the dengue virus increases the risk of acquiring the more serious disease , dengue haemorrhagic fever . with treatment , most of the patients can recover , " he said 假如其后再被另一类型登革热病毒感染，会出现更严重的疾病-登革出血热-的危险便会增加，在接受治疗后，大部份病人都可痊愈。
