Bacterial conjugation is one of the basic methods by which simple organisms, such as the single-celled bacterium, reproduce. It is a very basic form of copulation that often involves a transfer of DNA but no recombination following the said transfer. It occurs following the docking together of two bacteria, a donor and a recipient. It is sex in the bacterial world. The process of conjugation is made possible by “the presence of certain plasmids in the donor bacteria that possess genes for This arrangement results when two bacterial cells occur as a pair (joined together). Some of the cells in this arrangement might remain spherical while some might appear flattened, elongated, or bean-shaped. Examples: Streptococcus pneumonia, Moraxella catarrhalis, Enterococcus spp, Neisseria gonorrhea. Tetrad Bacterial conjugation allows plasmid molecules to transfer horizontally throughout a bacterial population, sometimes to distantly related organisms, and has played a central role in the dissemination of antibiotic resistance genes among bacterial pathogens. Horizontal transfer is mediated by a specialized plasmid‐encoded protein complex called the conjugative apparatus and relies on several Genetic transfers such as transformation, conjugation, and transduction are important phenomena affecting the understanding of evolution and have been used in genetic engineering laboratories to transfer genes of interest to allow their expression in target organisms. With hands‐on laboratory work on bacterial conjugation, students can clearly understand the basic concepts of genetic transfers. Conjugation is a type of horizontal gene transfer, a way for organisms to share genetic information with each other. Horizontal gene transfer can be contrasted with vertical gene transfer - the transmission of genetic traits from generation to generation, parent to offspring. Conjugation is how a bacterium can share the information on a plasmid with its neighbors. * Bacterial conjugation.

Bacterial conjugation is a sexual mode of genetic transfer in the sense that chromosomal material from two sexually distinct cell types is brought together in a defined and programmed process. However, in bacterial conjugation, the process involves only a portion (usually small) of the genome of one of the cells (the donor) and the complete genome of its sexual partner (the recipient), as opposed to sexual union in most higher organisms, which involves an interaction between the entire set bacterial conjugation and Ti This work highlights the importance of active surveillance of colistin-resistant organisms in soil. Moreover, investigations addressing the influence of animal Bacteria are disease-causing, microscopic, single-celled organisms with prokaryotic cell structures. They do not have membrane-bound organelles, including a true nucleus. Being the lowest and simplest form of life, they are found almost everywhere on earth and thus, are the most dominant living creature. Bacteria are thought to have been the first living organism to appear on earth about 4 During conjugation, two bacterial cells have to be in contact with each other (this contact is established by a pilus and athesins). For the transfer of genetic material to take place, one of the cells must not have the F-factor. Therefore, one has to be the donor and the other a recipient. Once it's successfully transferred to the recipient cell, the recipient cell becomes an F+ donor. The
