Gonococcal ophthalmia develop within 7 days of birth of a baby to an affected mother and is usually bilateral with intense conjunctivitis, copious purulent secretion and lid edema. Without proper urgent treatment, ulceration of the cornea leading to scarring will seriously affect vision. Complications In men, epididymitis, prostatitis and urethral stricture can result from untreated gonorrhoea. In women, Bartholinitis and abscess formation (causing trouble walking), pelvic inflammatory disease (PID) and Fitz-Hugh-Curtis Syndrome can occur. The most common result of untreated gonorrhea is PID, a serious infection of the female reproductive tract. PID causes scarring of the fallopian tubes which leads to increased risks of causing an ectopic pregnancy as a fertilized egg may not be able to pass through the narrowed, scarred fallopian tube. Ectopic pregnancies are serious conditions which are potentially life-threatening to the mother. There are several different genera of rhizobia. All of them belong to the Rhizobiales, a probably-monophyletic group of proteobacteria. Within that group, however, they are scattered among several different families: Agrobacterium is a closer relative of Rhizobium than the rhizobia that nodulate soybean (and may not really be a separate genus). The genes responsible for the symbiosis with plants, however, may be closer than the organisms themselves, acquired by horizontal transfer rather than from a common ancestor. The legume-rhizobium symbiosis is a classic example of mutualism, but its evolutionary persistence is actually somewhat surprising. Because several unrelated strains infect each individual plant, any one strain could redirect resources from nitrogen fixation to its own reproduction without killing the host plant upon which they all depend. But this form of cheating should be equally tempting for all strains, a classic tragedy of the commons.

S. typhi is a serovar of Salmonella. It causes the disease typhoid fever. The organism can be transmitted by the fecal-oral route -- it is excreted by humans in feces and may be transmitted by contaminated water, food, or by person to person contact (with inadequate attention to personal hygiene). Caulobacter crescentus is a gram-negative, oligotrophic bacterium widely distributed in aquatic environments. It plays an importante role in the carbon cycle. It is an important model to cellular differentiation and one of its most perceptible characteristics is that its two child-cells are very different from each other, one being mobile and the other fixed. The mobile one has a flagellum and swims until it finds a favorable environment, at which point it loses its flagellum and develops a new structure that lets the cell fix itself to a substrate. Bdellovibrio species are found in river water or soil and live an intraperiplasmic existence. To enrich for Bdellovibrio use NB/500 (nutrient broth at 1:500 dilution) and mix with hot soft agar with E. coli at 30°C for one week. Under the microscope, a Bdellovibrio appears as a comma-shaped motile rod that is about 0.3-0.5 by 0.5-1.4 µm in size with a barely discernible flagellum. Colonies of Bdellovibrio show up as a growing clear plaque in an E. coli lawn. Another notable feature of Bdellovibrio is the sheath that covers its flagellum. This is a rare characteristic among bacteria. This flagellum is lost when Bdellovibrio penetrates its prey.
