Ezubere iji
Listeria monocytogenes bụ microbacterium nwere gram nke nwere ike itolite n'etiti 4 ℃ na 45 ℃.Ọ bụ otu n'ime ihe ndị na-akpata ọrịa na-eyi ahụike mmadụ egwu na nri friji.Isi ngosipụta nke ọrịa bụ septicemia, meningitis na mononucleosis.Ngwa a dabara adaba maka nchọpụta qualitative nke Listeria monocytogenes na nri, ihe nlele mmiri, feces, vomit, mmiri mmiri na-eme ka nje bacteria na ihe atụ ndị ọzọ na-eji ụkpụrụ nke ezigbo oge fluorescence PCR. The kit bụ PCR-PRDY SYSTEM (Lyophilized) , nke nwere DNA amplification enzyme, reverse transcriptase, nzaghachi mmeghachi omume, kpọmkwem primers na nyocha achọrọ maka nchọpụta PCR fluorescent.
