ABSTRACT
El objetivo de este estudio fue identificar las especies de Candida spp. aisladas de secreción vaginal de pacientes embarazadas y no embarazadas y relacionarlas con la microscopía, síntomas y signos característicos de la vaginitis causada por esta levadura. Se estudiaron 743 muestras de secreción vaginal de pacientes que acudieron al Departamento de Bacteriología y Micología del Laboratorio Central en el 2015. Las muestras fueron sembradas en CHROM agar Candida y agar Sabouraud. La identificación se hizo por macro y micromorfología, pruebas bioquímicas, auxonograma y método comercial. En las 522 pacientes embarazadas se aislaron 536 Candida spp.: C. albicans 463 (86,4%), C. glabrata 46 (8,6%), C. krusei 9 (1,7%), C. parapsilosis 9 (1,7%), C. tropicalis 8 (1,5%), C. lusitaniae 1 (0,1%).En las 221 pacientes no embarazadasse aislaron 222 Candida spp.: C. albicans 163 (73,4%), C. glabrata 31 (14%), C. krusei 10 (4,6%), C. parapsilosis 9 (4,1%), C. tropicalis 6 (2,7%), C. guilliermondii 1 (0,4%), C. kefyr 1 (0,4%) y C. novergensis 1 (0,4%). Se observó un mayor porcentaje de aislamiento de Candida no albicansen las no embarazadas (26,6% vs 13,6%). En 15 pacientes (2%) se aislaron dos especies de Candida.Tanto en embarazadas como no embarazadas el prurito, la reacción inflamatoria y la presencia de pseudohifas fueron más frecuentes cuando el aislamiento era C. albicans. Enfatizamos la importancia de la siembra de las muestras en agar cromogénico para identificar y diferenciar especies de Candida para la epidemiología y un tratamiento eficazde la vaginitis causada por esta levadura.
The objective of this study was to identify Candida spp. isolated from vaginal secretion of pregnant and non-pregnant women and relate them with microscopy, symptoms and signs characteristic of vaginitis caused by this yeast. A total of 743 vaginal secretion samples wasstudied from patients consulting at the Department of Bacteriology and Mycology of the Central Laboratory in 2015. All samples were cultured on CHROM agar Candida and Sabouraud agar. The identification was made by macro and micromorphology, biochemical tests, auxonogram and commercial method. In pregnant patients (n = 522), 536 Candida spp. were isolated: C. albicans 463 (86.4%), C. glabrata 46 (8.6%), C. krusei 9 (1,7%), C. parapsilosis 9 (1.7%), C. tropicalis 8 (1.5%), C. lusitaniae 1 (0.1%). In no-pregnant patients (n = 221),222 Candida spp.were isolated: C. albicans 163 (73.4%), C. glabrata 31 (14%), C. krusei 10 (4.6%), C. parapsilosis 9 (4.1%), C. tropicalis 6 (2.7%), C. guilliermondii 1 (0.4%), C. kefyr 1 (0.4%) and C. novergensis 1 (0.4%).In the non-pregnant women, a higher percentage of non-albicans Candida species isolation was observed (26.6% vs 13.6%). Fifteen patients (2%) with two Candida species were detected. In pregnant as well non pregnant women, presence of pruritus, inflammatory reactions and and presence of pseudohifas were more frequent when Candida albicans was isolated.We emphasize the importance of culturing samples in chromogenic agar to identify and differentiate Candida species for epidemiology and an effective treatment of the vaginitis caused by this yeast.

Objective To preliminarily evaluate the performance and species specificity of Candida spp.latex immunochromatography kit for detecting Candida spp.in vaginal secretion.Methods The vaginal secretions in 354 cases of suspected vaginitis and 9 genus of 22 species of common vaginal infecting organisms were by adopting the smear/Gram staining and Candida spp.kit.The results were compared with those detected by smear/Gram staining semi-quantitative method.The detection performance and species specificity of Candida spp.kit for detecting clinical specimens were evaluated.Results Compared with the smear/Gram staining method,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value of Candida sp.kit were 93.81%,99.10%,97.31%,98.14% and 96.90%,respectively;compared the smear/Gram staining semiquantitative method,the Candida spp.kit for detecting Candida spp.in vaginal secretion still had higher specificity and acceptable sensitivity when the Candida spp.concentration was lower in specimens;in the speciese specificity evaluation,6 kinds of Candida spp.were positive and other 16 kinds of common vaginal infecting organisms all were negative.Conclusion The Candida spp.kit for detecting Candida spp.in vaginal secretion has higher clinical and species specificity,sensivity,positive prediction value and negative prediction value.
ABSTRACT
Objective To explore the infection and drug sensitivity of ureaplasma urealyticum(Uu)and mycoplasma hominis (Mh)in vaginal secretion of gynecological outpatients.Methods The infection and drug sensitivity test of Uu and Mh in va-ginal secretion samples of 1 800 patients collected from January 2015 to April 2016 were detected with mycoplasma culture i-dentification and counting drug sensitivity kit produced by Zhengzhou Antu Luke Bioengineering Co.,Ltd.Results The positive rate of Uu(57.27%)was significantly higher than that of Mh(2.78%,χ2=33.69,P<0.001).The positive rate of mycoplasma was highest in the age group of 31~35(77.09%),but that of Uu was highest in the age group of 21~25 (65.83%)and that of Mh in 36~40 years old group(9.09%),in addition that of multiple infection by Uu and Mh was highest in less than 20 years old group(20.51%).There were statistical difference for Un,Mh and co-infection by Un and Mh between age groups(χ2=15.505~36.574,P<0.01).The top three drugs sensitive for mycoplasma were josamycin, minocycline and doxycycline and that last three ones were clindamycin,thiamphenicol and sparfloxacin.The drug sensitive rates for 12 antibiotics against Uu were higher than those against co-infection by Uu and Mh,but those of erythromycin,gat-ifloxacin,azithromycin,clarithromycin and Luo Hongmei against Mh were lower than those against co-infecion of Uu and Mh.Conclusion The detection of mycoplasma and drug sensitivity in vaginal secretions provides the experimental basis for clinical diagnosis and treatment.
ABSTRACT
Objective To investigate the relationship between the bacterial vaginosis and 8 putative periodontal pathogen infection.Methods A total of 48 patients with bacterial vaginosis were collected and 47 healthy female patients were selectedin the control group.Vaginal secretion and subgingival plaque were obtained from the study group and the control group.The presence of Porphyromonasgingivalis (P.g),Tannerella forsythia (T.f),Treponemas denticola (T.d),Prevotell intermedia (P.i),Prevotella nigrescen (P.n),Peptostreptococcus micros (P.m),Fusobacteriumnucleatum (F.n) and Campylobacterrectas (C.r) was detected by DNA extraction and PCR method.Simultaneously,all the patients underwent a clinical periodontal examination of the teeth in community periodontal index,including plaque index (PLI),bleeding on probing (BOP),probing depth (PD) and clinical attachment loss (CAL) Results The prevalence of periodontal disease,PLI,BOP and CAL in the study group was significantly higher than in the control group (P＜0.05) and the PD had no statistically significant difference between the 2 groups (P＞O.05).The 2 groups were both detected 8 putative periodontal pathogens in the vaginal secretion and the subgingival plaque samples.The detection ratio of T.dfrom both the vaginal secretion and subgingival plaque samples was significantly higher in the study group than that in the control group (P ＜0.05),and other 7 pathogens showed no statistically significant difference (P ＞0.05) Conclusion The prevalence of periodontal disease was higher among the bacterial vaginosis patients.The 8 putative periodontal pathogens were normal flora in the subgingival plaque and vaginal secretion.Td might be relevant to the pathogenesis of bacterial vaginosis.
ABSTRACT
OBJECTIVE: Trichomonas vaginalis is the common cause of sexually transmitted diseases. The present study was performed to find the possibility of other transmission mode of T. vaginalis than sexual transmission. METHODS: Survivals of trophozoites suspended in various environmental conditions were measured by haemocytometer after trypan blue staining. Also, drying time of vaginal secretion exposed at different temperatures such as 4 degrees C, 26 degrees C, 30 degrees C were observed. RESULTS: The survival rates of T. vaginalis decreased as the temperatures of tap water increased. The survival rates of trophozoites were less than 10% at 30 min-exposure at 4d degrees C or 15 min-exposure at 26 degrees C water. Hot water above 45 degrees C killed trichomonads in 5 minutes or so. T. vaginalis soaked in water from swimming pool and in cleaning solution deceased in about 5 minutes. When trophozoites were put into urines of six healthy person, the survival rates of T. vaginalis showed less than 10% after 24 hr exposure except KT4. The survival rates of trichomonads were changed according to individual urine on examined day, and isolate of T. vaginalis. The vaginal secretion was put on slide glass and leave alone until complete drying in 4degrees C refrigerator, 26 degrees C and 30 degrees C incubator. For drying of vaginal secretion, it took 70 minutes, 44 minutes and 26 minutes in 4 degrees C refrigerator, 26 degrees C and 30 degrees C incubators, respectively. The survival of trichomonads showed no change until complete dryness of vaginal secretion. T. vaginalis immersed in tap water for 5 minutes, was divided into two or many fragments. Some trichomonads were partially or completely destructed. CONCLUSION: From above results, it is supposed that transmission of T. vaginalis by contaminated fomites such as toilet stool, toilet seats is possible although this type of transmission may not occur frequently.
