1. Molecular analysis of an Integrative Conjugative Element, ICEH, present in the chromosome of different strains of Mycoplasma hyopneumoniae
Diversification of bacterial species and pathotypes is largely caused by lateral gene transfer (LGT) of diverse mobile DNA elements such as plasmids, phages, transposons and genomic islands. Thus, acquisition of new phenotypes by LGT is very important for bacterial evolution and relationship with hosts. This paper reports a 23 kb region containing fourteen C

2. Pesquisa de anticorpos IgG séricos anti-lipoproteínas de Mycoplasma fermentans e Mycoplasma hominis ou anti-MAM (superantígeno de Mycoplasma arthritidis) em pacientes com artrite reumatóide ou lúpus eritematoso sistêmico / Search IgG anti-serum lipoproteins Mycoplasma fermentans and Mycoplasma hominis or anti-MAM (superantigen Mycoplasma arthritidis) in patients with rheumatoid arthritis or lupus erythematosus systemic
Rheumatoid Arthritis (RA) and Systemic Lupus Erythematosus (SLE) are autoimmune diseases of unknown etiology. Some species of mycoplasmas cause arthritis in animals and humans, and their lipid-associated membrane proteins (LAMPs) and Mycoplasma arthritidis mitogen (MAM superantigen) are potent stimulators of the immune system. Thus, it has been proposed that

A artrite reumatóide (AR) e o lúpus eritematoso sistêmico (LES) são doenças autoimunes de etiologia desconhecida. Algumas espécies de micoplasmas causam artrite séptica em seres humanos, sendo estas bactérias fortes candidatos à etiopatogênese destas doenças. O superantígeno MAM é uma proteína secretada por Mycoplasma arthritidis, que juntament

6. Detection of multiple mycoplasma infection in cell cultures by PCR
A total of 301 cell cultures from 15 laboratories were monitored for mycoplasma (Mollicutes) using PCR and culture methodology. The infection was detected in the cell culture collection of 12 laboratories. PCR for Mollicutes detected these bacteria in 93 (30.9%) samples. Although the infection was confirmed by culture for 69 (22.9%) samples, PCR with generic

7. Caracterização de proteinas imunodominantes de Mycoplasma penetrans e Mycoplasma fermentans
Micoplasmas são procariotos diminutos, desprovidos de parede celular e envoltos por uma membrana lipoproteica cujo pequeno genoma sintetiza a maioria das moléculas necessárias para crescimento e replicação. Dentre as dezesseis espécies isoladas do homem, Mycoplasma pneumoniae, agente causador da pneumonia atípica primária, e as espécies do trato uro

8. Detecção de Mycoplasma genitalium, M. fermentans e M. penetrans em pacientes com sintomas de uretrite e em indivíduos infectados pelo HIV-1 no Brasil
Neste trabalho investigamos a prevalência de três espécies de micoplasma recém-identificadas como patógenos humanos, M. genitalium, implicado em casos de uretrite não-gonocócica, e M. fermentans e M. penetrans, isolados de pacientes imunodeprimidos, e das duas espécies mais freqüentes no trato geniturinário, M. hominis e U. urealyticum. Foram estud

9. Complement Activation in Mycoplasma fermentans-Induced Mycoplasma Clearance from Infected Cells: Probing of the Organism with Monoclonal Antibodies against M161Ag
Mycoplasma fermentans, a cell wall-less prokaryote, is capable of infecting humans and has been suggested to serve as a cofactor in AIDS development. Recently, we discovered a novel lipoprotein with a molecular mass of 43 kDa originating from M. fermentans. This protein, named M161Ag, activated human complement via the alternative pathway and efficiently ind

10. Protein and antigen heterogeneity among strains of Mycoplasma fermentans.
The proteins and antigens of three strains of Mycoplasma fermentans were compared with those of a mycoplasma, designated "Mycoplasma incognitus," recently identified in tissues of AIDS patients. Previous studies have shown that "M. incognitus" is most likely not a new species but rather a strain of M. fermentans. In the present study, one- and two-dimensiona

11. Antibiotic susceptibilities of AIDS-associated mycoplasmas.
Because mycoplasmas may be a cofactor in the progression of human immunodeficiency virus infection to AIDS, their susceptibilities to antibiotics need to be known in the event that appropriate therapy is required. The mycoplasmas studied were a stock culture strain of Mycoplasma fermentans, two strains of M. fermentans isolated from patients with AIDS, M. fe

12. Search for the presence of six Mycoplasma species in peripheral blood mononuclear cells of subjects seropositive and seronegative for human immunodeficiency virus.
The prevalence of Mycoplasma fermentans, Mycoplasma pirum, Mycoplasma genitalium, Mycoplasma pneumoniae, Mycoplasma hominis, and Mycoplasma penetrans was investigated by using specific PCR assays with peripheral blood mononuclear cells from subjects infected or not infected with the human immunodeficiency virus (HIV). Only M. fermentans was detected in 5.8%
