BACKGROUND Stress alters the oxidant-antioxidant state and immune cell responses which disrupts its function to combat infection. Blastocystis hominis, a common intestinal protozoan has been reported to be opportunistic in immunocompromised patients namely cancer. B. hominis infectivity in other altered immune system conditions especially stress is unknown. We aimed to demonstrate the stress ef...

This study was carried out to elucidate by serological examination the etiological significance of mycoplasmas isolated from the upper urinary tract of patients with pyelonephritis. The occurrence of antibodies in patients with acute pyelonephritis, chronic pyelonephritis with or without exacerbation, or noninfectious urinary tract disease was compared by the indirect hemagglutination method. A...

Both Mycoplasma hominis and Trichomonas vaginalis utilize arginine as an energy source via the arginine dihydrolase (ADH) pathway. It has been previously demonstrated that M. hominis forms a stable intracellular relationship with T. vaginalis; hence, in this study we examined the interaction of two localized ADH pathways by comparing T. vaginalis strain SS22 with the laboratory-generated T. vag...

BACKGROUND Cryptosporidium species are important cause of diarrheal diseases in both developing and developed countries. This study aimed to compare the performance of several molecular methods for identification of Cryptosporidium species, and to detect genetic variation among each of these species isolated from Iran, Malawi, Nigeria, Vietnam and the United Kingdom. METHODS The oocysts DNA s...

OBJECTIVE To describe the frequency and antiparasitic in vitro susceptibility of Blastocystis hominis in patients admitted to theHospital Regional Lambayeque, Peru. MATERIAL AND METHODS A cross-sectional study was conducted from January to August 2015 at 313 patients of all ages. B. hominis detection was performed on serial fecal samples by direct microscopic examination and microculture in m...

The presence of the tetracycline resistance determinant tetM has been reported for Mycoplasma hominis (1, 2) and association with Tn916 genes established (3). To identify the mobile genetic element harboring this gene, genome analysis of M. hominis Sprott (isolated from a nongonococcal urethritis patient before 1978 [4]) and targeted PCR/amplicon sequencing of M. hominis 1630 (1984, arthritis i...

OBJECTIVE To investigate the possible involvement of human trichomonads (Pentatrichomonas hominis and Trichomonas tenax) other than Trichomonas vaginalis in the aetiology of vaginal trichomoniasis. METHODS Vaginal swabs taken from women attending antenatal clinics were tested for Trichomonas vaginalis by traditional assays (wet-mount microscopy and InPouch culture) and nucleic acid amplificat...

The aim of the present study was to investigate the association between Mycoplasma infection and infertility in male outpatients among a Chinese population. Epidemiological data, including prevalence, age distribution and antibiotic resistance profile of patients with an Ureaplasma urealyticum or Mycoplasma hominis infection were collected between 2009 and 2012. Among the 7,374 individuals anal...

BACKGROUND AND PURPOSE Blastocystis hominis has not been reported as an endemic disease in Taiwan, but high prevalence rates have been found among immigrants. Due to the increasing number of immigrants in Taiwan, B. hominis may become a public health problem in Taiwan. This study was performed to determine the prevalence of B. hominis among immigrant populations. METHODS Stool examination dat...
