Ureaplasma urealyticum is a urogenital commensal and often associated with localised infection. With the advent of monoclonal immunosuppressive therapy and improved diagnostic methods, reports of non-urogenital infections are accumulating. We report a rare case of U. urealyticum necrotizing soft tissue infection and left hip septic arthritis in a hypogammaglobulinaemic patient. Consideration of this organism as an etiological agent, and potential early use of nucleic-acid diagnostic investigation with empiric therapy including activity against Ureaplasma in this patient population may be warranted...

Urinary tract infections are a major cause of morbidity and hospitalization after renal transplantation. Patients treated with immunosuppressive drugs suffer not only from common uropathogens but also from opportunistic infections caused by unusual uropathogens. Sterile pyuria is associated with numerous infectious agents including viruses, fungi, and atypical or fastidious organisms. The objective of this study was to investigate the pathogens using real-time multiplex polymerase chain reaction (rtMPCR) assay in sterile pyuria of renal transplant recipients...

REVIEW
Michael Solomon, Ralf Henkel
The male factor contributes approximately 50% to infertility-related cases in couples with an estimated 12%-35% of these cases attributable to male genital tract infections. Depending on the nature of the infection, testicular sperm production, sperm transport, and sperm function can be compromised. Yet, infections are potentially treatable causes of infertility. Male genital tract infections are increasingly difficult to detect. Moreover, they often remain asymptomatic ("silent") with the result that they are then passed on to the relevant sexual partner leading to fertilization and pregnancy failure as well as illness of the offspring...

BACKGROUND: Mycoplasmas are frequently isolated from the genital tract. New molecular PCR-based methods for the detection of mycoplasmas can better define the real epidemiology of these microorganisms. The aim of this study was to evaluate the prevalence of mycoplasmas in a population of childbearing age women by means of PCR. METHODS: This 21-month multicentre observational study was conducted at four Italian clinical microbiology laboratories. Women reporting symptoms of vaginitis/cervicitis, or with history of infertility, pregnancy, miscarriage or preterm birth were included...

Objectives: The symbiosis of Trichomonas vaginalis and Mycoplasma hominis is the first described association between two obligate human parasites. Trichomonas is the niche and the vector for the transmission of M. hominis infection. This clinically significant symbiosis may affect T. vaginalis virulence and susceptibility to treatment. The aims of this study were to investigate the intracellularly present Mycoplasma and Ureaplasma species in T. vaginalis strains isolated from the vaginal discharge of infected women as well as to trace the diversity pattern among the species detected in the isolated strains...

BACKGROUND: Chorioamnionitis can induce pulmonary inflammation and promote bronchopulmonary dysplasia development, distinguished by alveolar simplification and impaired vascular growth. Chorioamnionitis is more common during the extremely preterm canalicular lung stage (crucial for vascular development); and increases the risk for subsequent sepsis. We hypothesized that single/combined exposure to chronic and/or acute inflammation induces pulmonary inflammatory responses and vascular changes...

BACKGROUND: Mollicutes detection can be cumbersome due to their slow growth in vitro. For this reason, the use of DNA based on generic molecular tests represents an alternative for rapid, sensitive and specific detection of these microorganism. For this reason, six previously described nucleic acid testing assays were compared to evaluate their ability to detect microorganisms belonging to the class Mollicutes. METHODS: A panel of 61 mollicutes, including representatives from the Mycoplasma, Acholeplasma, Mesoplasma, Spiroplasma and Ureaplasma genus, were selected to evaluate the sensitivity and specificity of these assays...

A deficiency in signal transducer and activator of transcription 3 (STAT3) is responsible for autosomal dominant hyperimmunoglobulin E syndrome, an immunodeficiency syndrome causing Staphylococcus aureus, Streptococcus pneumonia, Haemophilus influenzae, and, rarely, Pseudomonas aeruginosa and Aspergillus sp infections. Currently, intracellular pathogens are not targeted in the management of severe infections. The pathophysiologic mechanism of hyperimmunoglobulin E syndrome immunodeficiency has recently been linked to a disorder in the T helper 17 pathway and disruption of the interleukin -23/interleukin-17 axis...

BACKGROUND: Atypical wound pathogens may be so described because they are uncommon pathogens of soft tissue among human beings, or because they may be fastidious and difficult to recover/isolate in the laboratory. METHODS: A review of pertinent English-language literature was performed. RESULTS: These wound pathogens are a diverse lot, including aerobic and anaerobic gram-positive and gram-negative bacilli, non-tuberculous mycobacteria, and bacteria that cannot be characterized conventionally because they lack a cell wall (the Mycoplasmataceae)...

Ureaplasma spp. are associated with preterm birth. In recent times, it has become apparent that Ureaplasma parvum, but not Ureaplasma urealyticum, is of most relevance. We recently demonstrated this in Australian pregnant women and using high-resolution melt (HRM) PCR, further showed that U. parvum genotype SV6 was of particular significance. However, our assay was unable to identify multiple genotypes in the same sample, required a separate species-level qPCR for low titre samples and was not ideal for diagnostic laboratories due to the nature of HRM PCR result interpretation...
