Trichomoniasis vaginalis
The trichomoniasis vaginalis is cause by the flagellum protozoa-vagina hair infusoria of one species the most familiar sexually transmitted diseases.
Mainly infringe upon a female vagina, can also make a male urinary tract infection because of the sexual intercourse.Becoming adult women a Tricomonas vaginalis infection a rate can be up to 95%.
In the vagina that can be live on in mankind of the vagina hair infusoria.In the animal the inoculation the indol test, in addition to monkey vagina, the vaginas of other animals are all unwell proper in it of growth.Inside the vagina of some women although have the vagina hair the infusoria parasitism, can completely have no clinical symptom, be a bodily resistibility to turn down, PH inside the vagina because various reason become alkalescence, the vagina hair infusoria can in great quantities breed but appear a clinical symptom.Moreover, women after the trimester of pregnancy and menstruation, mensis, less because of lactic acid rod in the vagina, the PH is close neuter gender, also easily infect hair infusoria.The hair infusoria is mainly the way which passes a sexual intercourse to spread.Discover hairiness infusoria in its husband’s urethra, ketonuria liquid and prostate liquid in the women who have already confirmed to be get a hair trichomonal vaginitis.
Currently basis a few following aspects:
(1)Have both parties of sex contact a coinfection often originally a disease;
(2)Be taken bad age often in the living active young philtrum of 16-25 year olds, but other ages also have occurrence and the child seldom gets this disease;
(3)The prostitute is confusion because of sexual behavior, infection rate Gao, can reach to 30%;(4)This disease often exists in the meantime with gonorrhea.As a result think that the hair trichomonal vaginitis is one species sexually transmitted diseases.But this disease can also pass toilet seat, bathtub, crurs basin, underwear, sanitary napkin, sheet…etc. to indirectly infect.The pathogen of trichomoniasis vaginalis is a vagina hair drop flagellum insect.The body department presents a pear form, grow 10-30 microns and the breadth is 5-15 microns.General bigger than leukocyte, white blood cell, WBC 200%.The anterior extremity contains 4 root flagellums, the flagellum has around 2/3 insect body longus, used for climbing to move and explore the way.The insect body abdomen face can undulate to make the insect body make a spiral type kinematic.The flexible ability of the hair infusoria is also very strong, can often change its body to cut through to go forward a medium baffling thing.Insect body of front 1/3 contain nucleus, there is obvious nuclear membrane for the oval while hold still and the nucleoplasm, karyoplasm has the distribution even chromatin, also the axis cylinder stretch out a coda.The hair infusoria only has already nourished a body period but has no encapsulation period, with two cleavages or much split up method carry on breed.In the outside environment of indoor temperature, the activity ability is very strong, hypothermia(3-5 ? ) the activity ability obviously turn down, but can also live for 21 days and the dry hour easily dies.In addition to living on at the female vagina, the urethra is also an importance to dwell for rest place.It sometimes also is reside in an urinary bladder.
The hair infusoria is mainly live on in the squamous epithelium surface of vagina in, not the parasitism is at the columnar epithelium surface.Although the neck of uterus also is subjected to an infection, the infusoria detection rate is 13%.Urethra and urethra side gland is also the infusoria part more pleased than parasitism and the infusoria masculine gender rate reaches to 90%.The vagina hair infusoria often glues to attach to make amoeba at the epithelial cell kinematic.Crawl along in superior surface, trochlear surface or inferior surface of single stratum, story cell, calculate this kind of machine injury to cause a symptom;Moreover the infusoria releases a toxic material to cause a pathological changes, there can be serious cellular immunity in the infusoria can’t arrive of the top the subcutaneous tissue, subcutis;Thered is bacterial infection again to change vagina PH a value, and the inflammation cause tissue necrosis, these also be advantageous to infusoria of invade.
At the vagina, the infusoria can cause an acute inflammation reaction, make the vagina discharge, secretion increase, contain a great deal of coenocyte, the infusoria is in the vagina antrum or glue at the cell surface of the vagina mucous membrane, mucosa, but don’t get into a mucous membrane, mucosa(?).Often have a little by little small petechia and involve in granular layer, stratum granulosum and Ji cell stratum, story in the mucous membrane, mucosa surface.The blood capillary, capillary contains hyperplasia, proliferation phenomenon.
Generally want through the incubation period for 4-28 days after female vagina infection hair infusoria, cardinal performance vagina discharge, secretion of a great deal of bad smell pus, the discharge, secretion presents a foam form.The serious hour leucorrhea can mix a blood.Most patients have outside scorching hot feeling, dysuria, pain, frequent micturition, urgent micturition of the yin Sao Yang demulcent therapy, reconciliation, even intermittent hematuria etc..Symptom usually in menstruation, mensis in front and back, pregnancy, fatigue or sexual intercourse behind aggravate.Can discover outside yin inflammation, erosion, labium edema, vagina and the temple jugular mucous membrane, mucosa redness and urethritis, accidentally see a groin intertrigo…etc. while check.Serious patient vagina wall and neck of uterus have petechia and erosion and present “red bayberry form”, temple neck of typical model can hyperemia, edema.
The male urethra is also the cardinal place which infects infusoria.Have no symptom to have 50-90%.The performance of cause the urethritis is a pain in urination, frequent micturition, 50-60% contains the increment phenomenon of the urethra discharge, secretion, present pus or mucilage discharge, secretion, measure seldom, disappearance just after having 1 in the urethra mouth in the morning, urine, discharge, secretion often for interrupted sex of, hour sometimes have no.As a result don’t cause the patient’s attention very much, can not get pole of treatment.
