Ukuqubuka kwamuva nje komkhuhlane we-chikungunya kwenzeke eSifundazweni saseGuangdong, ezweni lakithi. Ngesonto eledlule, kubikwe amacala amasha acishe abe ngu-3,000 eGuangdong, athinta amadolobha angaphezu kweshumi. Lokhu kuqubuka komkhuhlane we-chikungunya akuveli ezweni lakithi. Ngokusho kweHhovisi Lezempilo Nokuhlela Umndeni leSifunda saseShunde, eDolobheni laseFoshan, eSifundazweni saseGuangdong, ukuqubuka kwalesi sifo kwavela ecaleni lomkhuhlane we-chikungunya owangeniswa uvela kwamanye amazwe eSifundazweni saseShunde ngomhlaka-8 kuJulayi. Lesi sifo sidluliselwa ngokushesha ngokulunywa umiyane we-Aedes (i-Aedes aegypti noma i-Aedes albopictus).
Kuyini iChikungunya?
Umkhuhlane we-Chikungunya ubangelwa yigciwane le-chikungunya, isifo esithathelwanayo esidluliselwa kakhulu ukulunywa umiyane we-Aedes. Izimpawu zomtholampilo zifaka phakathi umkhuhlane, ukuqubuka, kanye nobuhlungu bamalunga nemisipha. Lesi sifo saqala ukutholakala eTanzania ngo-1952, lapho kuqubuka khona umkhuhlane omkhulu kanye nobuhlungu obukhulu bamalunga phakathi kweqembu lezakhamuzi zendawo esifundeni saseMakonde Plateau eningizimu-mpumalanga ye-Afrika. Ososayensi kamuva bathola leli gciwane elingajwayelekile ngamasampula avela ezigulini kanye nomiyane, baliqamba ngokusemthethweni ngokuthi "Chikungunya" (okusho ukuthi "goba ngenxa yobuhlungu"). Ekuqaleni kwekhulu lama-21, umkhuhlane we-chikungunya waqala ukusabalala emhlabeni wonke. Lapho umiyane we-Aedes, owaziwa kakhulu ngokuthi "umiyane wezimbali," uluma umuntu noma isilwane esinomdlavuza, leli gciwane liyanda emzimbeni bese lifika ezinhlamvini zamathe, lapho lisakazeka khona ngemva kwesikhathi sokufukamela sezinsuku ezimbili kuya kweziyi-10. Ngemva kokutheleleka umiyane we-Aedes onegciwane, izimpawu zomtholampilo ziyavela ngemva kwesikhathi sokufukamela sezinsuku ezi-1 kuya kweziyi-12, ngokuvamile zibonakala njengomkhuhlane ophezulu, ubuhlungu bamalunga, ukuvuvukala kwamalunga, kanye nokuqubuka. Njengamanje, akukho ukwelashwa okuqondile komkhuhlane we-chikungunya, futhi ukunakekelwa okusekelayo kuyindlela eyinhloko emtholampilo. Ngakho-ke, ukuvimbela kusenesikhathi, izinyathelo zokulawula omiyane ezisebenzayo, kanye nokuhlolwa kokungena kwentela kanye nokuqapha ukuvimbela amacala angenisiwe kuyizinyathelo ezibalulekile zokulawula umkhuhlane we-chikungunya.
Ukukhishwa kwe-BigFish Nucleic Acid Kusiza Ukuvimbela Nokulawula Umkhuhlane we-Chikungunya
Ukuhlolwa kwe-Nucleic acid kuyithuluzi elibalulekile lokuvimbela nokulawula umkhuhlane we-chikungunya kusenesikhathi kanye nokulawula ukusabalala kwawo. I-Ultra Viral Nucleic Acid Extraction Reagent (BFMP25R) esanda kwethulwa yi-BigFish ikhipha i-viral nucleic acid kumasampula ngokushesha nangokuphumelelayo. Uma kuqhathaniswa nama-virtual nucleic acid extraction reagents ajwayelekile, i-BFMP25R ikhipha i-virtual nucleic acid ngenani le-Ct elingaphezu kokuphindwe kabili ngaphambili ekuhlolweni kwe-nucleic acid. Le reagent yokukhipha ifanele amasampula afana negazi eliphelele, i-serum, i-tissue homogenates, kanye ne-swab extracts ehlukahlukene. Uma isetshenziswa ne-BigFish fully automated nucleic acid extraction and cleansing instrument, i-nucleic acid extraction ingaqedwa ngamaqoqo amakhulu amasampula cishe ngemizuzu eyi-10, okwenza kube kuhle kakhulu ezimweni ezidinga ukuhlolwa kwe-nucleic acid enkulu, njengokuvimbela nokulawula ubhubhane.
Ukuze usize ekuvimbeleni nasekulawuleni umkhuhlane weChikungunya eSifundazweni saseGuangdong, uma usendaweni enesifo esiwumshayabhuqe futhi udinga ukukhishwa nokuhlolwa kwe-viral nucleic acid, ungaxhumana nathi ngokushayela inombolo engezansi. Sizokunikeza izivivinyo zamahhala ze-I-BigFishithuluzi lokukhipha nokuhlanza i-nucleic acid ngokuzenzakalelayo kanye nemithamo eyi-100 ye-reagent yokukhipha i-nucleic acid (ultra), futhi inikeze izinsizakalo zokufaka nokuqeqesha zamahhala endaweni. I-BigFish izolwa nawe ukuze ivikele impilo yabantu.
