Symptoms of gonorrhea The incubation period varies from 2 to 14 days with most symptoms occurring between days 2 and 5 after being infected from an infected partner. A small number of people may be asymptomatic for several months. Men In male patients dysuria accompanied by thick, copious, purulent (condensed milk-like) urethral discharge is the most common presentation. Examination show a reddened external urethral meatus. Without effective treatment, ascending infection could extend to the epididymis, testes or prostate causing symptoms such as scrotal pain or swelling. Men and women with rectal gonorrhea may present with anal discharge, perianal pruritus, tenesmus and rectal bleeding. Proctoscopy shows inflamed mucous membrane with little mucous. Corynebacterium diphtheriae is an aerobic Gram positive organism, characterized by non-encapsulated, non-sporulated, immobile, straigtht or curved rods with a lenght of 1-8 µ and width of 0,3-0,8 µ, which form ramified aggregations in culture (looking like 'Chinese characters'). It is a strictly human micro-organism. It produces a proteic exotoxin with 62 kiloDaltons, which is responsible for the signs of diphtheria. The inactivation of this toxin with a antitoxic serum (anatoxin) is the basis of the antidiphtheric vaccination. The bacterium is sensitive to the majority of antibiotics, such as the penicillins, ampicillin, cephalosporin, quinolones, chloramphenicol, tetracyclines, cefuroxime and trimethoprim.

Some have sheaths (Sphaerotilus) while others don’t. Bacteria like mycoplasmas that lack a hard cell wall don’t have any particular shape at all. Just like in animals, where size ranges from the giant blue whale to the tiny gnat, bacteria vary from 1 millimeter in diameter at the largest end of the scale to 20 nanometers in length at the smallest. The largest bacteria found so far can actually be seen without the use of a microscope (Thiomargarita namibiensis and Epulopiscium fischelsoni). The smallest known bacteria are so tiny that they were once thought to be viruses (Mycoplasmas). As long as there is enough food and moisture, the mass thrives. But when food and water are scarce, the mass separates into smaller blobs. The Plasmodium forms stalks topped by sphere-like fruiting bodies that contain spores that are carried by the rain or wind to new locations. Cellular slime molds also produce spores, but these germinate into amoeba-like cells. The cells happily go their individual ways, as long as food and water are available.
