1. Detecção de Mycoplasma pulmonis e Mycoplasma arthritidis no trato respiratório superior de ratos e bioteristas por cultivo e reação em cadeia da polimerase (PCR) / Detection of Mycoplasma pulmonis and Mycoplasma arthritidis in the upper respiratory tract of rats and technicians by culture and polymerase chain reaction (PCR)
Mycoplasma pulmonis and Mycoplasma arthritidis are species usually isolated from laboratory rats, causing losses and modifying results of research that use such animals. Mycoplasma pulmonis inhabit primary the respiratory tract, nasopharynx, and middle ear of murines causing the murine respiratory mycoplasmosis (MRM). In general, aerosols perform the transmi

2. Detecção de Mycoplasma pulmonis em ratos de biotérios
O presente estudo foi desenvolvido em ratos de dois biotérios, um em Niterói e outro no Rio de Janeiro, sendo um classificado como convencional controlado e o outro como convencional. O objetivo foi verificar a presença do Mycoplasma pulmonis em animais que apresentavam sintomas de doença respiratória e baixa produtividade. No biotério convencional con

3. Development of artificial replicative plasmids for transformation of Mycoplasma pulmonis, M. capricolum and M. mycoïdes subsp. mycoïdes, and disruption of the M. pulmonis hemolysin A gene by homologous recombination / Desenvolvimento de plasmídeos replicativos artificiais para transformação de Mycoplasma pulmonis, M. capricolum e M. mycoïdes subsp. mycoïdes, e dirupção do gene da hemolisina A de M. pulmonis por recombinação homóloga
Mycoplasmas are the smallest microorganisms capable of self replication known to date, responsible for many diseases in man and animals, infecting also plants and insects. They constitute a large group of bacteria, classified in different genera in the class Mollicutes, which main common characteristic, besides the small genome, is the absence of a cell wall

4. Imunoeletroforese do soro de ratos naturalmente infectados com Mycoplasma pulmonis e bioteristas expostos a biotérios infectados
Mycoplasma pulmonis foi isolado em aproximadamente 10(5) UFC/mL do lavado traqueal de ratos mantidos em biotérios convencionais da cidade de São Paulo. A transmissão do micoplasma por aerossol pode ocorrer entre os animais em até 120 cm. Esta condição favorece a sua transmissão para os bioteristas que também são expostos a este microrganismo. Como e

5. Identification of cross-reactive antigens between Mycoplasma pulmonis and Mycoplasma arthritidis.
Serological cross-reactivity between Mycoplasma pulmonis and Mycoplasma arthritidis was investigated by enzyme-linked immunosorbent assay, immunoanalysis of electrophoretic blots, and protein A immunoprecipitation reactions. The results demonstrate that one-way cross-reactivity was present in both hyperimmunized and naturally infected rats and that the predo

6. Pneumonia Due to Mycoplasma in Gnotobiotic Mice I. Pathogenicity of Mycoplasma pneumoniae, Mycoplasma salivarium, and Mycoplasma pulmonis for the Lungs of Conventional and Gnotobiotic Mice
Lutsky, Irving I. (Marquette University School of Medicine, Milwaukee, Wis.), and Avrum B. Organick. Pneumonia due to mycoplasma in gnotobiotic mice. I. Pathogenicity of Mycoplasma pneumoniae, Mycoplasma salivarium, and Mycoplasma pulmonis for the lungs of conventional and gnotobiotic mice. J.

7. Detection of Mycoplasma pulmonis in arthritic joints of rats by indirect immunoperoxidase staining.
Neonatal and 8-week-old rats were inoculated with Mycoplasma pulmonis. A portion of the animals developed polyarthritis. Indirect immunoperoxidase staining was used to identify the localization of M. pulmonis within arthritic joints. M. pulmonis antigen was most often observed within cartilage in the neonatal group and in synovial tissue in the 8-week-old gr

8. Construction and Use of Derivatives of Transposon Tn4001 That Function in Mycoplasma pulmonis and Mycoplasma arthritidis
Previous attempts to introduce transposon Tn4001 into Mycoplasma pulmonis and Mycoplasma arthritidis have not been successful, possibly due to functional failure of the transposon's gentamicin resistance determinant. Tn4001C and Tn4001T were constructed, respectively, by insertion of a chloramphenicol acetyltransferase gene and the tetM tetracycline resistan

9. Trypsin-sensitive, bovine serum albumin-dependent hemolysis activity in Mycoplasma pulmonis.
Although Mycoplasma pulmonis did not lyse normal erythrocytes, it rapidly lysed erythrocytes that had cytoskeletal deficiencies which allow increased diffusion of membrane glycophorin or that had been treated with trypsin to remove surface proteins. This hemolysis occurred only in the presence of bovine serum albumin and was eliminated by trypsin treatment o

11. Delayed hypersensitivity to nonviable Mycoplasma pulmonis in mice is enhanced by dextran sulfate.
The enhancing effect of dextran sulfate (DS) on delayed hypersensitivity to nonviable Mycoplasma pulmonis in mice was evaluated by means of delayed footpad swelling. Mice pretreated subcutaneously with nonviable M. pulmonis and DS had significantly increased delayed footpad swelling when the mice were injected subcutaneously in the footpad with the same anti

12. Gender Is a Major Factor in Determining the Severity of Mycoplasma Respiratory Disease in Mice
Gender is a significant factor in determining the susceptibility to and severity of pulmonary diseases in both humans and animals. Murine respiratory mycoplasmosis (MRM), due to Mycoplasma pulmonis infection, is an excellent animal model for evaluation of the role of various host factors on the development of acute or chronic inflammatory lung diseases.
