To identify tick-borne pathogens in blood samples from 68 dogs were examined for Babesia, Anaplasma/Ehrichia, Mycoplasma, and Hepatozoon spp. by using a molecular tool. The detection of DNA was performed using specific primers for partial 16S rRNA or 18S rRNA sequence, and amplicon sequences were analyzed. Our investigation detected Babesia gibsoni (26 dogs) and Anaplasma sp. AnHl446 (2 dogs), ...

The effectiveness of counterimmunoelectrophoresis (CIEP) for detecting human precipitating antibodies to mcyoplasma antigen was compared with the conventional complement fixation (CF) method in a double-blind experiment. Fifty-one sera from patients suspected of having acute mycoplasma infection were tested by both techniques. Dense precipitin lines to mycoplasma antigen developed in 28 sera wi...

Mycoplasma contaminations have a multitude of effects on the cultured cell lines that may influence the results of experiments or pollute bioactive substances used in human medicine. The elimination of mycoplasma contaminations of cell cultures has become a practical alternative to discarding and reestablishing important or irreplaceable cell lines. Different quinolones, tetracyclines, and pleu...

BACKGROUND It has been recognized that infectious agents, such as different bacteria and viruses, may play a role in the developing of rheumatoid arthritis (RA). Recently, the mycoplasma species has been implicated in the pathogenesis of RA. AIM The aim of this study was to design a multiplex PCR for rapid and simultaneous detection of Mycoplasma pneumoniae, Mycoplasma hominis, and Mycoplasma...

We have studied the ability of three different Mycoplasma species to induce proliferation of bone marrow-derived macrophages (BMM). We observed a significant mitogenic effect when BMM cells from BALB/c, DBA/2J, SJL, and C57BL/6 mice were incubated with membranes derived from Mycoplasma arginini or M. arthritidis but not when they were incubated with an equivalent amount of M. pulmonis membrane....

The DNAs of four Mycoplasma and one Acholeplasma species were found to contain methylated bases. All of the five species contained 6-methyladenine (m6Ade), the methylated base characteristic of prokaryotic DNA. The extent of methylation of adenine residues in the mycoplasmal DNA ranged from 0.2% in Mycoplasma capricolum to about 2% in Mycoplasma arginini and Mycoplasma hyorhinis with intermedia...

At least 13 mycoplasma species cause arthritis in animals. In some cases it remains chronic, and in particular Mycoplasma hyorhinis in swine and Mycoplasma synoviae in poultry clinically and histologically resemble rheumatoid arthritis in man. Of patients with serologically verified Mycoplasma pneumoniae infections 0.9% had arthritis. Usually it is mild, but may sometimes be the dominant clinic...

We present here the draft genome sequence of the first "Candidatus Mycoplasma haemobos" strain found in cattle in Mexico. This hemotropic mycoplasma causes acute and chronic disease in animals. This genome is a starting point for studying the role of this mycoplasma in coinfections and synergistic mechanisms associated with the disease.

The complete genome sequence of Mycoplasma hominis LBD-4 has been determined and the gene content ascribed. The 715,165-bp chromosome contains 620 genes, including 14 carried by a strain-variable prophage genome related to Mycoplasma fermentans MFV-1 and Mycoplasma arthritidis MAV-1. Comparative analysis with the genome of M. hominis PG21(T) reveals distinctive arrangements of repeat-containing...

Amplified fragment length polymorphism (AFLP) was used for typing avian mycoplasma species. Forty-four avian mycoplasma strains were successfully typed into eight distinct groups, with each representing a different species. Homology of AFLP patterns of 35% or less was used as a cutoff value to differentiate avian mycoplasma strains into different species.
