The genotype Blastocystis hominis is highly polymorphic. Therefore, a genetic marker would be a powerful tool for the identification or classification of B. hominis subtypes and could be used as a means to resolve the transmission route or origin of the parasite. To this end, 32 B. hominis isolates were collected from patients and/or staff members of two long-term health care facilities (facili...

A gene from Mycoplasma hominis PG21 similar to the tuf gene encoding the elongation factor Tu (EF-Tu) of Escherichia coli was cloned and sequenced. The 1193-bp open reading frame flanked by a putative promoter and a potential stem-and-loop structure encoded a 44-kDa polypeptide. The tuf gene of M. hominis PG21 has the lowest G + C content seen in prokaryotes (38.2%). A gene (mhlmp1) encoding a ...

Mycoplasma hominis is an opportunistic human mycoplasma. Two other pathogenic human species, M. genitalium and Ureaplasma parvum, reside within the same natural niche as M. hominis: the urogenital tract. These three species have overlapping, but distinct, pathogenic roles. They have minimal genomes and, thus, reduced metabolic capabilities characterized by distinct energy-generating pathways. A...

OBJECTIVE To evaluate the role of Mycoplasma hominis as a vaginal pathogen. DESIGN Prospective study comprising detailed history, clinical examination, sexually transmitted infection (STI) and bacterial vaginosis screen, vaginal swabs for mycoplasmas and other organisms, follow up of bacterial vaginosis patients, and analysis of results using SPSS package. SETTING Genitourinary medicine cli...

Although the idea of bacteria causing different types of cancer has exploded about century ago, the potential mechanisms of carcinogenesis is still not well established. Many reports showed the involvement of M. hominis in the development of prostate cancer, however, mechanistic approach for growth and development of prostate cancer has been poorly understood. In the current study, we predicted...

Human cryptosporidiosis is caused primarily by Cryptosporidium hominis, C. parvum and C. meleagridis. To accelerate research on parasites in the genus Cryptosporidium, we generated annotated, draft genome sequences of human C. hominis isolates TU502_2012 and UKH1, C. meleagridis UKMEL1, also isolated from a human patient, and the avian parasite C. baileyi TAMU-09Q1. The annotation of the genome...

BACKGROUND The study of sperm-mycoplasma interaction has been focused on the effects of infection on sperm quality, but few studies have reported the direct interaction of this bacterium with spermatozoa. METHODS Selected populations of viable, motile and infection-free human spermatozoa from three healthy men were incubated with 15-480 multiplicity of infection (MOI) units of DiIC18-labelled...

Blastocystis hominis and Endolimax nana exist as two separate parasitic organisms; however co-infection with the two individual parasites has been well documented. Although often symptomatic in immunocompromised individuals, the pathogenicity of the organisms in immunocompetent subjects causing gastrointestinal symptoms has been debated, with studies revealing mixed results. Clinically, both B....

Mollicutes are the smallest and simplest self-replicating microorganisms. Despite the minimal genome and apparent lack of complexity, mycoplasmas show a high degree of adaptation to the most diverse environments. Mycoplasma hominis is a human sexually transmitted mycoplasma which is able to establish a biological association with Trichomonas vaginalis, a pathogenic flagellated protist. M. homin...

The existence of a symbiotic relationship between Trichomonas vaginalis and Mycoplasma hominis, which is the first reported example of symbiosis between two obligate human pathogens, has been recently reported by our research group. In this work, we examined the cellular location of M. hominis in respect to T. vaginalis. By using gentamicin protection assays, double immunofluorescence, and conf...
