Vagina trichomonad sickness is one kind of most common nature spread disease which causes by the flagella protozoan - - vagina trichomonad.
Mainly encroaches upon the feminine vagina, because may also the sexual intercourse cause the masculine urinary tract infection. The grown woman vagina infusorium infection percentage may reach as high as 95%.??The vagina trichomonad can only parasite in humanity’s vagina. In the animal vaccination experiment, besides the monkey vagina, other animal’s vagina ill is suitable for its growth. In although some women vagina has the vagina trichomonad parasitism, but may not have the clinical symptoms completely, when body’s resistivity decreases, when in the vagina PH each kind of reason turns the alkalinity, the vagina trichomonad may reproduce massively has the clinical symptoms. Moreover, woman after gestation period and menstruation, because in vagina’s bacillus lacticus are few, PH close neutrality, also easy to infect the trichomonad. The trichomonad is mainly through sexual intercourse’s way dissemination. Already confirmed in contracts in the trichomonad vaginitis’s woman, in her husband’s urethra, the urine and the prostate gland fluid the discovery has the trichomonad.
? At present according to the following several aspects:
(1) has natural contact both sides often simultaneously to infect this sickness;
(2) morbidity age often in 16-25 year old of sex life active young people, but other ages also have the occurrence, the child are very few this sickness;
because (3) prostitute the sexual relationship is chaotic, the infection percentage is high, may reach 30%; (4) this sickness often also exists with gonorrhea. Therefore thought that the trichomonad vaginitis is one kind of spread disease. But this sickness may also through the restroom seat, the bathtub, the foot trough, the underwear, the sanitary napkin, the bedding and so on indirect infection. The vagina trichomonad gets sick the pathogen is the vagina wool drop mastigote. The body department assumes the pear, the length 10-30 microns, the width is 5-15 microns. Generally is bigger than 2 times the white blood cell. Front end has 4 flagellas, the flagella approximately has 2/3 insect length of body, uses in creeping along and exploring the way. The polypite thoracic and abdominal area may fluctuate causes the polypite to make the screw type movement. Trichomonad’s expansion ability is also very strong, often can change its physique to pass through in the advance the encumbrance. Polypite first 1/3 has the cell nucleus, static when is an ellipse, has the obvious karyotheca, the nuclein has the distribution even chromatin, and has the columella to stretch out the rear part. The trichomonad only has nourishes the body time not to have the cystic stage, carries on the reproduction by the binary fission or the multi-fission method. In the room temperature external environment, energy is very strong, when low temperature (3-5?) energy decreases obviously, but can also live for 21 days, is dry when easy to die. Besides may parasite in the feminine vagina, the urethra is also one perches the place importantly. Sometimes also resides in the urinary bladder.
??Trichomonad main parasitism in vagina’s squamous epithelium surface, but is not the parasitism in the columnar epithelium surface. Although the cervix also receives the infection, but the infusorium discovery rate is only 13%. Nearby the urethra and the urethra the gland is also the infusorium in the parasitic spot, the infusorium masculine gender rate reaches 90% happily. The vagina trichomonad often sticks in the epithelial cell makes the amoeba movement. Crawling in single-layer cell’s above or, extrapolated that this kind of mechanicalness damage causes the symptom; Moreover the infusorium release toxic material causes the pathological change, in the infusorium cannot arrive under the epidermis organizes to be possible to have the serious cell infiltration; Had the bacterial infection to change the vagina PH value again, and the inflammation caused the organization necrosis, these were also advantageous to infusorium’s invasion.
??In the vagina, the infusorium may cause the acute inflammation to respond that makes the vagina secretion to increase, the content massive coenocytes, the infusorium or sticks in the vagina cavity in the vagina mucous membrane cell surface, but does not enter in the mucous membrane. In the mucous membrane surface common micro small bleeding point, implicates the pellet level and the echinate cell level. The blood capillary has the proliferation phenomenon.
??After the feminine vagina infects the trichomonad, generally must pass through 4-28 day-long incubation period, the main performance massive stink purulent vagina secretion, the secretion assumes the foaming state. The serious time leucorrhea may mix has the blood. The most patients have the vulva pruritus and the scalding hot feeling, the urination difficulty, the ache, frequent micturition, the urgency of urination, even intermittent hematuria and so on. Symptom often around menstruation, pregnancy, weary or sexual intercourse postemphasis. When inspection the detectable vulva inflammation, the erosion, lip of vulva dropsy, the vagina and the cervix of the uterus mucous membrane blush and the urethritis, occasionally see the inguen to scratch and so on rottenly. The serious patient vaginal wall and the cervix have the bleeding point and the erosion, assume the model “the Myrica rubra shape”, the cervix of the uterus to be possible the hyperemia, dropsy.
??The masculine urethra also infects infusorium’s main place. The symptomless occupies 50-90%. Causes the urethritis performance for the urine pain, frequent micturition, 50-60% have the urethra secretion to increase the phenomenon, assumes the purulent or the mucous secretion, the quantity are very few, only in the morningtide has a micro drop in the urethral meatus place, after the urination vanishes, secretion often for discontinual, intermittent. Therefore does not bring to patient’s attention extremely, results in not to the limit the time treatment.
