Bakteri

Bakteri (dari kato Latin bacterium; jamak: bacteria) adolah kalompok organisme nan indak mampunyoi membran inti sel. Organisme ko tamasuak ka dalam domain prokariota jo baukuran ketek sangaik (mikroskopik), sarato mampunyoi paran gadang dalam kahidupan di bumi. Babarapo kalompok bakteri tanamo sabagai agen panyabab infeksi jo panyakik, samantaro kalompok lainnyo dapek maagiah manpaaik dibidang pangan, ubek, jo industri. Struktur sel bakteri relatif sederhana: tanpa nukleus/inti sel, karangko sel, jo organel-organel lain sarupo mitokondria dan kloroplas. Hal ikolah nan manjadi pambeda antaro sel prokariot jo sel eukariot nan labiah kompleks.Todar K. 2008.

Bakteri dapek ditamukan di ampia sado tampek: di tanah, aia, udaro, dalam simbiosis jo organisme lain ataupun sabagai agen parasit (patogen), bahkan dalam tubuah manusia.Anesti V, McDonald IR, Ramaswamy M, Wade WG, Kelly DP, Wood AP. 2005. Isolation and molecular detection of methylotrophic bacteria occurring in the human mouth. Environ Microbiol 7(8):1227-38.Gallego V, Garcia MT, Ventosa A. 2005.Methylobacteriumvariabile sp. nov., a methylotrophic bacterium isolated froman aquatic environment.

Pado umumnyo, bakteri baukuran 0,5-5 μm, tapi ado bakteri tatantu nan dapek mancapai diameter 700 μm, iyolah Thiomargarita. Umumnyo mampunyoi dindiang sel, sarupo sel tumbuahan jo cindawan, tapi jo bahan pambantuak nan amaik babeda (peptidoglikan). Babarapo jinih bakteri basipaik motil (talok manggarik) jo mobilitasnyo ko dek adonyo flagel.

 Bakteri Gram positif jo negatif 
Dalam maagiah antibiotik musti dikataui jinih bakterinyo apokoh Gram positif atau negatif.
