Actinomyces urogenitalis bacteremia and tubo-ovarian abscess after an in vitro fertilization (IVF) procedure.

ABSTRACT: We describe the first case of bacteremia due to Actinomyces urogenitalis. Bacteremia was secondary to a tubo-ovarian abscess following transvaginal oocyte retrieval. Identification was established by matrix-assisted desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and confirmed by 16S rRNA gene sequencing. A. urogenitalis should be considered as a potential causative agent of infection after gynecological procedures.

Project description:BackgroundMelioidosis, the disease caused by Burkholderia pseudomallei is endemic in the Northeastern part of Thailand, South-East Asia, and Northern Australia. The pelvic involvement of disease is rare even in an endemic area. Therefore, we describe in this report the clinical presentation, management, and outcome of the patient with primary tubo-ovarian abscess due to melioidosis.Case presentationA 31-year-old Thai cassava farmer woman presented with fever and abdominal pain at left lower quadrant for one month. She also had pain, swelling, and redness of the genitalia without any ulcer. She had odorless whitish vaginal discharge. The pelvic examination revealed excitation pain on the left side of her cervix. Transvaginal ultrasonography revealed a large left tubo-ovarian abscess size 9.4 × 4.8 cm located at anterior of the uterus. Urgent exploratory laparotomy revealed left hydrosalpinx with a large amount of pus. The pus culture grew Burkholderia pseudomallei. The computer tomography of the abdomen revealed multiple hepatosplenic abscesses. The patient underwent left salpingo-oophorectomy and pus drainage. The pathological examination of excised left adnexa revealed chronic and acute suppurative inflammation with necrotic tissue. She was given intravenous ceftazidime for one month, and her clinical symptom improved. She was diagnosed with type 2 diabetes mellitus at this visit and treated with insulin injection. She continued to take oral co-trimoxazole for 20 weeks. The final diagnosis was disseminated melioidosis with left tubo-ovarian abscess and hepatosplenic abscesses in a newly diagnosed morbidly obese diabetic patient.ConclusionBurkholderia pseudomallei should be considered as the causative organism of gynecologic infection among patient with risk factor resided in an endemic area who do not respond to standard antibiotics. The pus culture from the site of infection is the only diagnostic method of pelvic melioidosis, appropriate antibiotics, and adequate surgical drainage were the components of the successful outcome.

Project description:Background and Objectives: Actinomyces species are part of the normal flora of humans and rarely cause disease. It is an uncommon cause of disease in humans. The clinical features of actinomycosis have been described, and various anatomical sites (such as face, bones and joints, respiratory tract, genitourinary tract, digestive tract, central nervous system, skin, and soft tissue structures) can be affected. It is not easy to identify actinomycosis because it sometimes mimics cancer due to under-recognition. As new diagnostic methods have been applied, Actinomyces can now more easily be identified at the species level. Recent studies have also highlighted differences among Actinomyces species. We report a case of Actinomyces viscosus bacteremia with cutaneous actinomycosis. Materials and Methods: A 66 years old male developed fever for a day with progressive right lower-leg erythematous swelling. Blood culture isolates yielded Actinomyces species, which was identified as Actinomyces viscosus by sequencing of the 16S rRNA gene. In addition, we searched for the term Actinomyces or actinomycosis cross-referenced with bacteremia or "blood culture" or "blood stream" from January 2010 to July 2020. The infectious diseases caused by species of A. viscosus from January 1977 to July 2020 were also reviewed. Results: The patient recovered well after intravenous ampicillin treatment. Poor oral hygiene was confirmed by dental examination. There were no disease relapses during the following period. Most cases of actinomycosis can be treated with penicillin. However, clinical alertness, risk factor evaluation, and identification of Actinomyces species can prevent inappropriate antibiotic or intervention. We also compiled a total of 18 cases of Actinomyces bacteremia after conducting an online database search. Conclusions: In summary, we describe a case of fever and progressive cellulitis. Actinomyces species was isolated from blood culture, which was further identified as Actinomyces viscosus by 16S rRNA sequencing. The cellulitis improved after pathogen-directed antibiotics. Evaluation of risk factors in patients with Actinomyces bacteremia and further identification of the Actinomyces species are recommended for successful treatment.

Project description:BackgroundInfertility is estimated to affect approximately 9-30% of reproductive-aged couples. Several conditions involving one or both partners may contribute to infertility. The aim of this study is to evaluate the role of asymptomatic genital tract infections in the outcome of In Vitro Fertilization (IVF) in couples with infertility.MethodsA total of 285 infertile couples were enrolled in the study. Vaginal/endocervical swabs and semen samples were collected and subjected to microbiological analysis. Spermiograms were carried out on semen specimens, and lactobacilli were quantified in vaginal swabs. Data were associated with IVF results and analysed by using non parametric tests and multivariate analysis.ResultsMicrobiological analysis showed that 46.3% of couples presented with an asymptomatic genital tract infection. Spermiogram results showed a significantly diminished motility of sperm cells in samples positive to microbiological testing compared to negative specimens. Enterococcus faecalis was the most prevalent species (11.6%) in positive semen samples and was found to negatively affect both sperm morphology (p = 0.026) and motility (p = 0.003). Analysis of genital swabs from females showed that the presence of E. faecalis (p<0.0001), Escherichia coli (p = 0.0123), Streptococcus agalactiae (p<0.0001), and Gardnerella vaginalis (p = 0.0003) was significantly associated to reduced levels of vaginal lactobacilli. Association of microbiological data with IVF outcome showed that 85.7% of IVF+ couples was microbiologically negative, while IVF was successful in just 7.5% of couples infected with E. faecalis and/or U. urealyticum and/or M. hominis (p = 0.02).ConclusionsThe results show the negative impact of E. faecalis on sperm quality and the association of definite bacterial pathogens with reduced levels of vaginal lactobacilli. The presence of E. faecalis and/or U. urealyticum and/or M. hominis in genital samples of infertile couples is predictive for a negative outcome of IVF.
