The isolation of pleuropneumonia-like organisms (PPLO) from the urethral secretions of patients with non-gonococcal urethritis has been reported by many workers and has led to the suggestion that they may be a possible cause of this condition, although they have also been found in the genital tract of apparently healthy males. Other organisms of the pleuropneumonia group are known to be associa...

The interaction, between mycoplasma (PPLO) and human or rabbit leukocytes was examined in vitro. Upon incubation of M. hominis or M. arthritidis for 2 hr with rabbit peritoneal exudate granulocytes or leukocytes from human peripheral blood, no killing of mycoplasma was observed either in the presence or absence of type-specific antiserum. However, (14)CO(2) production from glucose-1-(14)C was s...

mycoplasma synoviae (m. synoviae) is a major worldwide poultry pathogen that causes serious economic losses in the poultry industry. this study was designed to detect m. synoviae through culture isolation and polymerase chain reaction (pcr) assay to demonstrated the involvement of m. synoviae infection in trachea and the lung/air sac samples taken from commercial broiler chicken farms in 3 m...

Controversy exists concerning the relation or distinction of pleuropneumonia-like organisms (PPLO) and L-type erganisms (Smith, Bacteriol. Rev. 28:97, 1964). While some feel that PPLO and L organisms may be identical, i.e., that PPLO are stabilized forms derived from bacteria (Barile et al., Oral Surg. Oral Med. Oral Pathol. 16:1395, 1963), others recognize sufficient differences to warrant pla...

Mycoplasma synoviae (M. synoviae) is a major worldwide poultry pathogen that causes serious economic losses in the poultry industry. This study was designed to detect M. synoviae through culture isolation and polymerase chain reaction (PCR) assay to demonstrated the involvement of M. synoviae infection in trachea and the lung/air sac samples taken from commercial broiler chicken farms in 3 m...

Mycoplasma bovine mastitis is a highly contagious disease, usually associated with clinical cases refractory to antibiotic treatment. The aim of this study was the isolation species in cattle milk samples from dairy herds Chile. Bulk tank selected by convenience 91 Holstein Friesian located Los Rios (66) and Lagos (25), two most important Regions country, were collected. Additionally, 100 indiv...

Pleuropneumonia-like organisms (PPLO) are the crabgrass of tissue culture. Many reports exist in the literature of successful attempts to eliminate these organisms from tissue cultures, but usually such reports were stimulated by the failure of some previously described method to be successful in the hands of the investigator. Although our cultures exhibited no overt manifestations of contamina...

The pleuropneumonia-like organisms (PPLO) are recognized as a group of rather fastidious microorganisms. Various peptones, infusions, and serum supplements have been examined by many investigators relating to the development of a medium satisfactory for the in vitro cultivation of these organisms (Morton et al., 1951; Edward, 1947; and others). However, few reports of examinations of the agar i...

Acute oophoritis and salpingitis were commonly observed in weanling mice injected intraperitoneally with murine pleuropneumonia-like organisms of the catarrhal type (4 strains). Organisms of the injected strain were regularly recovered in cultures from the ovary or uterus during the 3rd to the 5th week but not after the 12th week. They were also obtained from the vagina through the 5th week and...
