The resistance of gonococcus to physical and chemical factors is very weak, in 42 ℃ can survive 15 minutes, 52 ℃ to survive 5 minutes, 60 ℃ will die within 1 minute, in a completely dry environment 1-2 hours to die, but in an incompletely dry environment and pus can remain infectious for more than 10 hours, or even days. Very sensitive to general disinfectants, 1:4000 silver nitrate solution can die within 7 minutes, 1% phenol, 1-3 minutes to die, 0.1% mercury solution can also make its rapid death. Gonococcus suitable temperature of 35-36 ℃, PH 7.2-7.5, containing 5%-7% carbon dioxide humid conditions for growth, cocci are generally ovoid or kidney-shaped, no side hairs, spores, often arranged in pairs, contact surface flat or slightly depressed diameter is generally 0.6-0.8 microns, Gram stain is often negative.
