[Efficiency of bacteriological culture and the immunofluorescent assay to detect Campylobacter fetus in bovine genital fluids]. / Eficiencia del cultivo bacteriológico y de la inmunofluorescencia en la detección de Campylobacter fetus en fluidos genitales bovinos.

Bovine genital campylobacteriosis is a reproductive disease that affects cattle production. It is caused by Campylobacter fetus subspecies, C. fetus fetus (Cff) and C. fetus venerealis (Cfv). The aim of this study was to identify the presence of C. fetus in genital fluids by bacteriological culture and direct immunofluorescence (DIF) and to compare the results. Two groups of 6 heifers and 5 bulls, one infected with Cff (Cff group) and the other with Cfv (Cfv group) were formed. Two heifers and 2 bulls, all of them uninfected, made up the control group. Samples of cervicovaginal mucus and preputial fluid were processed by culture and DIF. In the Cff group, 100% of the heifers and 80% of the bulls were infected, while in the Cfv group, 50% of the heifers and 60% of the bulls were infected. The degree of agreement (Kappa values) from benchmarking diagnostic techniques were 0.57 for heifers in the Cff group and 0.52 for heifers in the Cfv group, whereas the values for bulls were 0.17 and 0.27, respectively. Heifers yielded more positive results in the DIF assay than in the culture, exhibiting 5.6% increase in the Cff group and 7.4% in the Cfv group. The lowest percentage of positive results for DIF in bulls, 40% less for the Cff group and 5.2% for the Cfv group, could be due to improper sampling. Kappa values showed moderate agreement for the heifers and low for the bulls.

Infecciones bacterianas del tracto reproductivo masculino y su papel en la fertilidad / Bacterial infections of the male reproductive tract and their role in fertility

Antecedentes: El espermatozoide es una célula altamente especializada encargada de llevar el material genético paterno hasta el tracto reproductivo femenino en búsqueda del oocito, no obstante durante su desplazamiento puede interactuar con sustancias, otras células e incluso microorganismos que puede transportar desencadenando procesos infecciosos que alteran el éxito reproductivo. Objetivo: Describir las bacterias involucradas en la alteración de la función reproductiva y sus efectos sobre calidad espermática, así como la capacidad de los espermatozoides para transportar infecciones y diseminarlas al tracto reproductivo femenino. Resultados: Las infecciones bacterianas que afectan el tracto reproductivo masculino se clasifican en infecciones de transmisión sexual, del tracto urinario y las asociadas a la microbiota bacteriana, donde están implicadas una gran variedad de agentes etiológicos como Chlamydia trachomatis, Ureoplasma urealyticum, Mycoplasma hominis, Escherichia coli y los Staphyloccoccus coagulasa negativos. Aún es controversial el efecto de estos gérmenes sobre los parámetros seminales así como la presencia de microbiota en el semen; su diagnóstico depende de la calidad de la muestra, de la sensibilidad de la técnica de detección y de los factores de riesgo que presente el individuo. Conclusión: Los procesos inflamatorios e infecciosos en el trato reproductivo masculino influyen en la fertilidad, por lo que se requiere profundizar en el estudio de estos procesos, establecer más y mejores métodos diagnósticos y pautas para el autocuidado que disminuyan la propagación de estos agentes patógenos.

Introduction: Spermatozoon is a highly specialized cell responsible for carrying the paternal genetic material toward the oocyte. During its journey in the female reproductive tract, the sperm cell interacts with substances, cells and also microorganisms that can be transported, thus triggering infectious processes that could alter reproductive success. Objective: Describe the species of bacteria involved in the alteration of sperm cells reproductive function and their effect on the sperm quality. In addition, evaluate the ability of the sperm cell to carry infections and disseminate them in the female reproductive tract. Results: Bacterial infections that affect the male reproductive tract are classified as sexually transmitted infections, urinary tract infections, and infections associated with bacterial microbiome. Chlamydia trachomatis, Ureoplasma urealyticum, Mycoplasma hominis, Escherichia coli and coagulase-negative Staphylococcus are the main etiologic agents of these infections. The presence of bacteria in semen and their effect of in semen parameters are still controversial. To probe that bacteria are present in semen depends on the quality of the sample, the sensitivity and specificity of the detection technique and the patient risk factors. Conclusion: Inflammatory and infectious processes in the male reproductive treatment affect fertility; therefore, further study of the role of thoseprocesses, establishment of more and better diagnostic methods and guidelines for self-care to decrease the spread of these pathogens will be necessary.

Impact of infection on the secretory capacity of the male accessory glands.

INTRODUCTION: Studies that compare the impact of different infectious entities of the male reproductive tract (MRT) on the male accessory gland function are controversial. MATERIALS AND METHODS: Semen analyses of 71 patients with proven infections of the MRT were compared with the results of 40 healthy non-infected volunteers. Patients were divided into 3 groups according to their diagnosis: chronic prostatitis NIH type II (n = 38), chronic epididymitis (n = 12), and chronic urethritis (n = 21). RESULTS: The bacteriological analysis revealed 9 different types of microorganisms, considered to be the etiological agents, isolated in different secretions, including: urine, expressed prostatic secretions, semen and urethral smears: E. Coli (n = 20), Klebsiella (n = 2), Proteus spp. (n = 1), Enterococcus (n = 20), Staphylococcus spp. (n = 1), M. tuberculosis (n = 2), N. gonorrhea (n = 8), Chlamydia tr. (n = 16) and, Ureaplasma urealyticum (n = 1). The infection group had significantly (p < 0.05) lower: semen volume, alpha-glucosidase, fructose, and zinc in seminal plasma and, higher pH than the control group. None of these parameters was sufficiently accurate in the ROC analysis to discriminate between infected and non-infected men. CONCLUSION: Proven bacterial infections of the MRT impact negatively on all the accessory gland function parameters evaluated in semen, suggesting impairment of the secretory capacity of the epididymis, seminal vesicles and prostate. These findings were associated with an infectious related significant increase of semen pH. None of the semen parameters evaluated can be suggested as a diagnostic tool for infection.

Aplicación de método molecular en la detección de Mycoplasma genitalium en hombres y en mujeres embarazadas / Molecular detection of Mycoplasma genitalium in men and pregnant women

Mycoplasma genitalium es un patógeno oportunista del tracto genital. En el hombre es causa de uretritis, en tanto que en mujeres ha sido implicado en la etiología de cervicitis y de enfermedad inflamatoria pelviana (EIP). El objetivo de este estudio fue determinar la prevalencia de M. genitalium en pacientes masculinos con uretritis y en muestras vaginales de mujeres embarazadas. Se obtuvo muestras de secreción uretral en 37 pacientes con uretritis y de muestras vaginales de 50 consecutivas mujeres embarazadas, determinándose la presencia de M. genitalium mediante reacción de polimerasa en cadena (RPC). Las muestras de secreción uretral fueron también evaluadas en busca de Chlamydia trachomatis, Neisseria gonorrhoeae y Ureaplasma sp en tanto que en las de origen vaginal se investigó la microbiota y presencia de micoplasmas de tipo genital. Veintitrés casos fueron clasificados como uretritis no gonocóccica (UNG) y 14 como enfermedad gonocóccica. M. genitalium fue detectado en 3 de 23 (13,04 por ciento) varones con UNG; en dos casos asociado a Ureaplasma sp, y en un paciente como agente único. C. trachomatis fue detectado en 7 pacientes con UNG y en uno con gonorrea. Ureaplasma sp fue aislado en 13 (35,1 por ciento) pacientes, 8 casos de UNG y en 5 con gonorrea. El microorganismo fue detectado también en 6 (15 por ciento) de 40 mujeres; en 5 casos en presencia de microbiota normal (score de Nugent 0-3), y en un caso en presencia de vaginosis bacteriana. Ureaplasma spp fue aislado en las seis muestras positivas. En conclusión, este estudio demuestra que M. genitalium debe ser también considerado en la etiología de la UNG así como en el tracto genital inferior en la mujer embarazada, en presencia de una microbiota vaginal normal.

Scutular tinea of the scrotum: report of two cases.

Infections caused by dermathophytes in the scrotal skin are uncommon especially due to Microsporum gypseum, which may form scutular or favus-like lesions. We report two patients with this type of tinea: one immune suppressed by HIV infection and another immunocompetent without comorbidity. In the literature we found only two reports in immunocompetent patients and some in immune suppressed with similar symptoms.

Ultrasound of tropical and infectious diseases that affect the scrotum.

Ultrasonography of the scrotum permits assessment of testicular and extratesticular masses with high sensitivity. It can differentiate a variety of conditions involving the scrotum, testicles, and epididymis with similar clinical manifestations, including infectious and tropical diseases. The authors performed conventional and color Doppler ultrasonographic examinations in 76 patients who presented with scrotal pain, swelling, and/or tenderness. Their diagnoses included sexually transmitted disease (eg, gonorrhea, syphilis, chlamydial infection), tuberculosis, mumps, and various tropical diseases (eg, filariasis, leishmaniasis, schistosomiasis, paracoccidioidomycosis). The most common imaging findings were enlarged hypoechoic testes, hypervascularity, small hydroceles, and cutaneous edema. This report reviews these and other possible presentations of tropical and infectious diseases affecting the scrotum, emphasizing ultrasound findings that facilitate diagnosis.

Experience in management of Fournier's gangrene.

We report our experience and results in the management of Fournier's gangrene. Fournier's gangrene is a synergistic infective necrotizing fasciitis, which involves perianal, perineal and genital regions, originated mostly from colorectal and genitourinary sources. Charts and records from 28 patients with Fournier's gangrene diagnosed between 1993 and 1997 were reviewed. The mean patients age was 57.8 years (range, 22-82 years); mean hospital stay was 19 days. Eighteen patients (64.3%) were diabetic. The most common source of gangrene was ischiorectal abscess in 22 patients (78.6%). Colostomy was performed on 14 patients (50%) and cystostomy on 7 patients (25%). Ten patients (35.7%) died because of sepsis. In conclusion, medical and surgical treatment should be aggressive. Colostomy should only be performed if sphincter complex is damaged. Multidisciplinary management is mandatory, because of high morbidity and mortality.

Assessment in the diagnosis of male chronic genital tract infection.

Different methodologies have been proposed to interpret the microbiological findings associated with contaminating, indigenous microbiota of the anterior urethra. In order to solve the controversy related to the diagnosis of chronic seminal infections in asymptomatic young adults, the results applying Stamey and Meares' criteria were compared with those obtained when semen cultures were studied for significant bacteriospermia. A total of 218 consecutive asymptomatic male partners of infertile couples were evaluated by the four-specimen technique described by Stamey and Meares' with the addition of semen (SM). Infection was detected in 46% by SM, while semen cultures (SC) showed a prevalence of infection of 41%; 73 patients were positive by both criteria and 102 negative; 27 patients were positive by SM technique in prostate fluid while their semen cultures were negative; 16 patients had positive semen cultures and were considered negative by SM. The kappa statistic indicated a good degree of agreement between both methodologies (kappa = 0.61, z = 8.68, p < 0.001). The estimated risk of being considered negative attributable to the semen culture (27 patients) was 25% (attributable risk = gamma ac- = 0.2550), and of being considered positive attributable to the semen culture (16 patients) was 26% (gamma ac+ = 0.2579). The 95% confidence limits were estimated in 12 to 39%, and in 13 to 31%, respectively. In view of these results, to establish the diagnosis of chronic prostatitis, the addition of prostatic fluid or voided urine cultures after prostatic massage, must be performed. Semen culture confronted with first-voided urine avoid overestimating seminal infection.

Paracoccidioidomycosis of the male genital tract. Report of eleven cases and a review of Brazilian literature.

Eleven cases of involvement of the genital tract in paracoccidioidomycosis were collected in a retrospective study of the clinical records of 683 patients seen in Porto Alegre, Rio Grande do Sul, Brazil. These cases are herein summarily reported. Eighteen similar cases were gathered in review of the Brazilian literature. Obtained data are discussed.

Genital ulcers: etiology, clinical diagnosis, and associated human immunodeficiency virus infection in Kingston, Jamaica.

Individuals presenting consecutively with genital ulcers in Kingston, Jamaica, underwent serological testing for human immunodeficiency virus (HIV) infection, chlamydial infection, and syphilis. Ulcer material was analyzed by multiplex polymerase chain reaction (M-PCR) analysis. DNA from herpes simplex virus (HSV), Haemophilus ducreyi, and Treponema pallidum was detected in 158 (52.0%), 72 (23.7%), and 31 (10.2%) of 304 ulcer specimens. Of the 304 subjects, 67 (22%) were HIV-seropositive and 64 (21%) were T. pallidum-seroreactive. Granuloma inguinale was clinically diagnosed in nine (13.4%) of 67 ulcers negative by M-PCR analysis and in 12 (5.1%) of 237 ulcers positive by M-PCR analysis (P = .03). Lymphogranuloma venereum was clinically diagnosed in eight patients. Compared with M-PCR analysis, the sensitivity and specificity of a clinical diagnosis of syphilis, herpes, and chancroid were 67.7%, 53.8%, and 75% and 91.2%, 83.6%, and 75.4%, respectively. Reactive syphilis serology was 74% sensitive and 85% specific compared with M-PCR analysis. Reported contact with a prostitute in the preceding 3 months was associated with chancroid (P = .009), reactive syphilis serology (P = .011), and HIV infection (P = .007). The relatively poor accuracy of clinical and locally available laboratory diagnoses pleads for syndromic management of genital ulcers in Jamaica. Prevention efforts should be intensified.

Prostatodynia in United Nations peacekeeping forces in Haiti.

Prostatodynia is a clinical entity associated with voiding symptoms and pelvic pain suggestive of prostatitis but with a normal prostate examination and without evidence of inflammation or infection in expressed prostatic secretions. The problem tends to be chronic and is vexing in its management. Although thought to be a common condition, prevalence data are generally lacking. From June to October 1995, the U.S. Army's 86th Combat Support Hospital provided medical support to a multinational United Nations peacekeeping force in Haiti. Patients diagnosed with prostatodynia were more common (13 cases) than men with other urologic problems (urolithiasis, 6 cases; urinary tract infection, 6 cases; scrotal abscess/mass, 2 cases; epididymitis, 1 case). Patients tended to be young (mean age 29.8), had multiple visits, failed to respond to multiple courses of antibiotics for presumed "prostatitis," and denied recent sexual relations. Some patients reported having had similar symptoms on prolonged separation from their spouses in the past that resolved with resumption of normal intercourse. Masturbation, however, had no impact on symptoms and was painful in some individuals. Terazosin, an alpha-antagonist, and stress-reduction therapy led to improvement in some patients' symptoms. A discussion of these retrospective findings in light of what is known about the possible etiologies and treatment of prostatodynia is presented. Prostatodynia appears to be a common problem in deployed troops and can lead to frequent use of medical services. Physicians supporting long deployments need to be aware of this entity.

Identificación de DNA de papilomavirus humano en condilomas anogenitales de una población masculina / DNA identification of human papillomavirus in anogenital condyloma of a male population

Human Papillomaviruses (HPV) are the cause of benign human anogenital lesions where HPV 6 and HPV 11 are most commonly found. Conversely, HPV 16, 18, 31 and 33 are frequently detected in genital carcinomas and are thus considered as oncogenic types. In order to analyze the prevalence of specific HPV types in an Argentine male population, 43 anogenital lesions from different patients with diagnosis of condyloma acuminata were analyzed. These lesions were localized in different regions of the male genitalia comprising the corona glandis, urethral meatus, skin of the penis, scrotum and anus. The biopsies were screened for the presence of HPV 6, 11, 16, 18, 30, 31 and 33 by Southern blot at different stringent conditions of hybridization (Tm -48 degrees C and Tm -20 degrees C). HPV DNA was found in 41 examined cases (95.3) with a clear prevalence of HPV 6 and HPV 11 types (51.2 and 23.3 respectively). Six samples (14.0) were positive only under nonstringent conditions of hybridization. Mixed infections between HPV 16, 18, 30, 31, 33 or a HPV 30 related type with HPV 6 or HPV 11 were detected in 8 specimens (18.6). Only one case was between HPV 16 and HPV 30. Two additional samples were only positive for HPV 30. Experiments in progress about the prevalence of HPV types in female lesions as well as in normal subjects will contribute to complete the description of the epidemiology of these infections in Argentina.
