Treatment of gonorrhea. The mainstay of treatment is the appropriate use of antibiotics. An increase in antibiotic resistance has led to the decline in use of penicillin for treating gonorrhoea. Nowadays, a third generation cephalosporin such as ceftriaxone is recommended for treating gonorrhoea. Doctors usually prescribe a single dose of one of the following antibiotics to treat gonorrhea: Cefixime Ceftriaxone Ciprofloxacin Ofloxacin Levofloxacin. As coinfection with chlamydial is common, doctors often prescribe a combination of antibiotics, such as ceftriaxone and doxycycline or azithromycin, which will treat both diseases. Follow up treatment is needed to ensure the organism has been eradicated. Sexual contacts should also be screened and treated if necessary. Vertical transmission Pregnant mothers infected with gonorrhea, can transmit the disease to their babies during childbirth. Agrobacterium tumefaciens causes crown-gall disease in plants, the disease is characterised by a tumour like growth on the infected plant at the junction between the root and the shoot. Tumors are induced by the transfer of a transferred DNA (T-DNA) segment form the bacterial tumour-inducing (Ti) plasmid A. rhizogenes induces root tumors, its plasmid is call Ri (root-inducing). The plasmid T-DNA is incorporated into the genome of the host cell by homologous recombination, and the virulence (vir) genes on the T-DNA are expressed, causing the gall to form. The T-DNA carries genes for the biosynthetic enzymes for the production of unusual amino acids octapine and nopaline. It also carries genes for the biosyntheis of plant hormones auxin and cytokinins. By altering the hormone balance in the plant cell, the division of those cells cannot be controlled by the plant, and tumors from.

These photosynthetic bacteria paved the way for today's algae and plants. Cyanobacteria grow in the water, where they produce much of the oxygen that we breathe. Once considered a form of algae, they are also known as blue-green algae. The human body consists of millions of different cells. A bacterium consists of a single cell. A bacterium’s genetic information is contained in a single DNA molecule suspended in a jelly-like substance called cytoplasm. In most cases, this and other cell parts are surrounded by a flexible membrane that is itself surrounded by a tough, rigid cell wall. A few species, such as the mycoplasmas, don’t have cell walls. In 1973, a Dallas resident went out to the backyard only to stumble upon a reddish, jelly-like mass pulsating in the grass. News reports on the discovery claimed that a new life form had been found, and many people couldn’t help recalling the cult classic sci-fi thriller The Blob. Scientists called to the scene, however, put any fears of menacing goo or alien creatures to rest by identifying the mass as an unusually large (46 centimeters or more than 14 inches in diameter) plasmodial slime mold.
