Iqembu B le-Streptococcus Nucleic Acid

I-Group B Streptococcus (GBS), eyaziwa nangokuthi i-streptococcus agalcatiae, iyigciwane eliyi-gram-positive elivame ukuhlala endaweni engezansi yokugaya ukudla kanye ne-urogenital tract yomzimba womuntu. Cishe u-10%-30% wabesifazane abakhulelwe banendawo yokuhlala yesitho sangasese se-GBS. Abesifazane abakhulelwe basengozini yokuthola i-GBS ngenxa yezinguquko endaweni yangaphakathi yomgudu wokuzala ezibangelwa izinguquko emazingeni ama-hormone emzimbeni, okungaholela emiphumeleni emibi yokukhulelwa njengokubeletha ngaphambi kwesikhathi, ukuqhekeka kwe-membrane ngaphambi kwesikhathi, kanye nokuzalwa kwengane isishonile, futhi kungaholela nasekuthelelekeni kwabesifazane abakhulelwe. Ngaphezu kwalokho, u-40%-70% wabesifazane abatheleleke nge-GBS bazodlulisela i-GBS ezinganeni zabo ezisanda kuzalwa ngesikhathi sokubeletha ngomsele wokuzalwa, okubangela izifo ezithathelwanayo ezibangelwa yi-neonatal sepsis kanye ne-meningitis. Uma izingane ezisanda kuzalwa zine-GBS, cishe u-1%-3% wazo zizoba nezifo ezihlaselayo ekuqaleni, kanti u-5% uzoholela ekufeni. I-neonatal group B streptococcus ihlotshaniswa nokutheleleka kwe-perinatal futhi iyigciwane elibalulekile lezifo ezithathelwanayo ezinzima njenge-neonatal sepsis kanye ne-meningitis. Le khithi ihlonza ngokunembile ukutheleleka kwe-streptococcus yeqembu B ukuze kuncishiswe izinga lokutheleleka kanye nokulimala kwayo kwabesifazane abakhulelwe kanye nezinsana ezisanda kuzalwa kanye nomthwalo wezomnotho ongadingekile obangelwa ukulimala.
