RESUMEN
Objective@#To investigate the prevalence of urogenital tract infections with Ureaplasma urealyticum (UU) and human papilloma virus (HPV) in males of reproductive age and the associated factors.@*METHODS@#Using the multi-stage cluster sampling method and a structured questionnaire, we conducted an investigation among 18－50 years old males in Songjiang District, Shanghai, from August 2016 to July 2018. We collected secretory specimens from the urogenital tract of the subjects and detected the infections of UU and HPV by laboratory examination.@*RESULTS@#Among the 621 males included in this study, 279 (44.93%) were found infected with UU, 18 (2.90%) with HPV, and 15 (2.42%) with both UU and HPV. Univariate analysis showed that smokers had a higher rate of UU infection (50.54% ［140/277］) than non-smokers (40.41 ［139/344］), and those with senior high school or secondary technical school education had a higher rate of HPV infection (4.84% ［12/248］) than others (1.61% ［6/373］). Binary stepwise logistic regression analysis revealed a higher risk of UU infection in the subjects with junior high school or lower education than in others (OR = 0.61, 95% CI: 0.39－0.96) as well as in smokers than in non-smokers (OR = 1.46, 95% CI: 1.01－2.01).@*CONCLUSIONS@#The prevalence of UU infection is high, while that of HPV is low among men of reproductive age in Songjiang, Shanghai. The screening of UU infection should be enhanced among men of reproductive age, especially among smokers and those with lower education.
RESUMEN
Abstract] Objective To study the roles of IL-12 and IL-23 in the development of protective im-munity and pathological changes during chlamydial urogenital infection.Methods C57BL/6J wild type (wt) mice and mice deficient in IL-12p35 (IL-12p35 KO) or IL-12p40 (IL-12p40 KO)were inoculated in-travaginally with 1×104 IFU of live Chlamydia muridarum ( C.muridarum) organisms.Half mice of each group were reinfected on day 114 after primary infection.Vaginal swabs were taken every 3 or 4 days to mo-nitor live organism shedding.The mice were sacrificed after 114 or 143 days of primary infection and the va-ginal tract and kidney samples were collected for pathological analysis.The numbers of chlamydial inclusion bodies and bacteria in kidney homogenates were titrated after 100 days of primary infection.Results The infection time courses of mice deficient in either IL-12p35 or IL-12p40 were similar after primary infection, but were prolonged as compared with the wild type mice.All mice regardless of genotypes developed severe pathological damages in upper genital tracts with no significant difference among different groups.Almost all IL-12p40 KO mice and some IL-12p35 KO mice showed pathological changes in kidney samples.No obvious abnormality was observed in any of the kidneys from wild type mice.Neither the age-matched IL-12p35 KO nor IL-12p40 KO mice developed any gross pathological changes in kidney in the absence of chlamydial in-fection.C.muridarum inclusions were detected in kidney samples with gross pathological damages from IL-12p35 KO mice and IL-12p40 KO mice.No inclusions were ever detected in kidneys from the wild type mice.The numbers of chlamydial inclusions in the IL-12p40 KO mice were much higher than those of the IL-12p35 KO mice.Live bacteria were detected in mice deficient in either IL-12p35 or IL-12p40, but not in the wild type mice.No significant difference with the number of live bacteria was found between IL-12p35 KO mice and IL-12p40 KO mice.Conclusion IL-12 and IL-23 could inhibit the spread of C.muridarum in-fection from genital tract to kidney.The deficiency of IL-12 or IL-23 might relate to the renal lesions induced by Chlamydia infection.
RESUMEN
Objective To investigate the situation of urogenital Ureaplasma urealyticum (Uu) and Mycoplasma hominis(Mh) in-fection and the drug sensitivity of the mycoplasmas ,and provide references for clinic treatment of urogenital-tract mycoplasmas in-fection .Methods Culture ,identification and drug-sensitivity test of mycoplasmas were performed on 677 specimens collected from suspected mycoplasma-infection patients by using Biomerieux mycoplasma kit .Results In the 677 patients ,the detection rates of Uu single infection was 49 .3% (334/677) ,Uu and Mh double infection was 13 .9% (94/677) ,Mh single infection was 1 .1% (8/677) .The detection rate in men and women were 22 .2% and 65 .6% respectively .The sensitivity tests indicated that the total sensi-tive rates of mycoplasmas to pristinamycin ,josamycin ,doxycycline ,tetracycline ,and erythromycin were 97 .4% ,91 .7% ,81 .9% , 73 .4% ,65 .1% ,respectively .Conclusion The incidence of urogenital mycoplasma infection in women is higher than that in men . Uu is the predominant mycoplasma in urogenital tract infection in the study .Pristinamycin ,josamycin ,doxycycline ,tetracycline ,and erythromycin can be chosen as the fist-line drugs for the treatment of urogenital Uu infection .
RESUMEN
OBJECTIVE To realize the situation of the infection of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) and the drug resistance among the female patients with urogenital tract infection.METHODS Totally 813 specimens in the female patients with urogenital tract infection were collected,cultured and tested for drug sensitivity with mycoplasma test drug sensitivity kit.RESULTS From the specimens of 813 cases the infection of Uu was in 296 cases(36.4%),the infection of Mh in 13 cases(1.6%),and the mixed was in 71(8.7%) cases,totally 380 cases(46.7%) were infected.The results of drug sensitivity showed that the sensitivities of Uu and Mh to josamycin,doxycycline and minocyclin were remarkable and the drug resistance of Uu and Mh to ofloxacin was the most prominent.CONCLUSIONS The infection of Uu and Mh is high among the femalepatients with urogenital tract infection.Especially the infection of Uu is usual.Uu and Mh have high drug resistance to many antibiotics,especially to ofloxacin.There is some difference between the drug resistances of Uu,Mh and Uu+Mh.To treat the infection of Mycoplasma some antibiotics are good choices,such as josamycin,doxycycline and minocyclin.
