Survey of plasmids in various mycoplasmas.
نویسندگان
چکیده
Thirty-three strains representing 15 distinct Mycoplasma, Acholeplasma, and Spiroplasma species were examined for the presence of plasmid DNA by agarose gel electrophoresis. The electrophoretic patterns of the DNAs of three strains, Mycoplasma sp. strain 747, Spiroplasma mirum strain SMCA, and M. hominis strain 1257, suggested the presence of a plasmid with molecular weights of approximately 70, 10, and 9 megadaltons, respectively. The functions of these plasmids are currently unknown.

Survey on the genital Mycoplasmosis by multiplex PCR
Mycoplasmas hominis, Mycoplasmas genitalium and Ureaplasma urealyticum are associated with infections of the genitourinary tract, reproductive failure, and neonatal morbidity and mortality. A multiplex PCR was developed for simultaneously detection of these Mycoplasmas species in a single amplification reaction. The total number of 104 samples was collected from 104 women’s genital specimens wi...
متن کاملDevelopment of a replicable oriC plasmid for Mycoplasma gallisepticum and Mycoplasma imitans, and gene disruption through homologous recombination in M. gallisepticum.
The genome of Mycoplasma gallisepticum strain R(low) has been sequenced completely, but subsequent genetic studies have been limited by the lack of a replicable vector system. In this study, replicable plasmids were constructed for M. gallisepticum and Mycoplasma imitans using the oriC region upstream from the soj gene. The oriC plasmids of M. gallisepticum (pGTLori) and M. imitans (pMIori) rep...
متن کاملThe prevalence of Mycoplasma hyorhinis contamination in tissues samples from cancer patients: A Brief Report
Infectious agents cause 15-20% of cancers worldwide. The infectious agents and contamination may be caused by a local chronic and advanced local inflammatory response, or by tumorization. Mycoplasma contamination can interfere with biological agents and cause DNA damage which affects gene expression, and disrupts the control of cell cycle inspection and apoptotic responses. Mycoplasmas are wide...
متن کاملHaemotropic Mycoplasmas (Haemoplasmas): A Review
Haemoplasmas contain Eperythrozoon and Haemobartonella species, which are widespread causes of animal and human infections. These obligatory cell parasites were previously known as Hemobartonella; now hemotropic mycoplasmas. These bacteria are identified by the lack of cell wall and their small genome. The usual diameter is between 0.3 and1μm. Mycoplasmasarepolymorphi...
