Complement pathway activity in the killing of Pentatrichomonas hominis was investigated in this study. At 10(5) organisms per ml, P. hominis was completely killed by the presence of 1% normal human serum. In contrast, no killing effect on P. hominis was observed when specific antibodies were absorbed or when the complement was destroyed. Moreover, Mg2+-ethylene glycol-bis-(beta-aminoethyl ether...

Previous studies by the authors have shown that the protozoan parasite Blastocystis hominis succumbed to a cytotoxic monoclonal antibody with a number of cellular and biochemical features characteristic of apoptosis in higher eukaryotes. The present study reports that apoptosis-like features are also observed in growing cultures of axenic B. hominis upon exposure to metronidazole, a drug common...

BACKGROUND Mycoplasma hominis and Ureaplasma urealyticum are important causative agents of vaginitis, cervicitis, postpartum sepsis, reproductive infections and infertility in both males and females. OBJECTIVES According to the uncertain prevalence of U. urealyticum and M. hominis in Iranian infertile females, the present study was carried out to determine the prevalence of U. urealyticum and...

background blastocystis is a common protozoan parasite in mammals, birds, amphibians,reptiles, fish, arthropods, and annelids. this parasite has some subtypes, which pathogenicity status of them still remained controversial. some of blastocystis subtypes are potentially pathogenic to human. objectives this study has identified the blastocystis hominis subtypes and their prevalence rates in hama...

BACKGROUND Methicillin resistant Staphylococcus hominis (MRSHo) are important human pathogens in immunocompromised patients. However, little is known regarding its population structure and staphylococcal chromosomal cassette mec (SCCmec) content. METHODOLOGY/PRINCIPAL FINDINGS To assess the population structure and the SCCmec content of S. hominis, 34 MRSHo and 11 methicillin-susceptible S. h...

Blastocystis (B.) hominis was considered to be a member of normal intestinal flora in the past, but in recent years it has been accepted as a very controversial pathogenic protozoan. In this study, 52 individuals whose stool examination revealed B. hominis were evaluated for clinical symptoms. Metronidazole was administered for 2 weeks to the patients infected with B. hominis. After 2 weeks of ...

Mycoplasma hominis infections are easily missed because conventional methods for bacterial detection may fail. Here, 8 cases of septic mediastinitis due to M. hominis are reported and reviewed in the context of previously reported cases of mediastinitis, sternum wound infection, pleuritis, or pericarditis caused by M. hominis. All 8 patients had a predisposing initial condition related to poor ...

Indirect hemagglutinating and immunofluorescent antibody responses to Herpesvirus hominis types 1 and 2 were compared to neutralizing antibody responses in infected humans from whom H. hominis type 1 or 2 was isolated. The indirect immunofluorescent antibody test was shown to be the most sensitive and specific for primary human infections. The sensitivity and specificity of the indirect hemaggl...

Clinical findings in 36 immunosuppressed patients with lower respiratory tract infection or bacteremia with Actinobacillus hominis are described. Animal contact was only recorded for three patients; nine patients died despite appropriate antimicrobial treatment. Although infections with this microorganism seem to be rare, the fact that 37 of 46 strains characterized in this study have been foun...

The protozoan parasite, blastocystis hominis, has been studied by transmission electron microscopy in the stool samples of 320 patients. Various ultrastructural characteristics are noted and the incidence of this parasite infestation studied. The vacuolar form is the most common form. There is a strong correlation between the disease condition and the presence of blastocystis hominis (p<00001)....
