“…iners, both these serotypes having been reported hitherto as occurring only in birds (Edward & Kanarek, 1960;Roberts, 1964;Dierks, Newman & Pomeroy, 1967). The isolation of avian serotypes from pigs raises the question of whether these mycoplasmas were, in fact, laboratory contaminants.…”

SUMMARYSeveral mycoplasmas isolated from pigs and designated B strains were previously found to be different from Mycoplasma hyorhinis and M. granularum, and to comprise four distinct serotypes. In the present study three of these serotypes were identified as M. laidlawii, M. gallinarum and M. iners, respectively. One serotype represented by mycoplasma ~3 could not be identified. The isolation of avian serotypes from pigs is discussed in the light of host specificity of mycoplasmas.

“…Later conclusive evidence has been presented by the development of air sac lesions in experimentally exposed poults (Yoder and Hofstad, 1964;Yamamoto and Bigland, 1965;Dierks et al, 1967;Rhoades, 1971b) and by enbryo in fection (Yamamoto and Bigland, 1966;Rhoades 1971a). …”

“…meleagridis is widely distributed among turkey flocks in the United States (Adler et al, 1958;Kumar et al, 1963;Yoder and Hofstad, 1966;Dierks et al, 1967), Canada (Bigland and Benson, 1968) and Britain (Roberts, 1963). Adler et al (1958) isolated the organism from air sac lesions of poults from 8 of 10 breeding flocks and Kumar et al (1963) observed airsacculitis associated with M. meleagridis in 24% of 1,197 culled poults.…”

“…The agglutina tion (Kleckner, 1960;Kelton and Van Roekel, 1963;Hofstad, 1964 andDierks et al, 1967) antiglobulin (Adler and DaMassa, 1964), fluorescent antibody Sadler, 1964 andRhoades, 1969b), growth inhibition (Kelton and Van Roekel, 1963;Dierks et al, 1967 andOgra and, complement fixation (Frey and Hanson, 1969) and metabolic inhibition (Ogra, 1972) tests have been used to identify M. meleagridis and to differentiate it from other avian mycoplasmas. Polyacrylamide gel electrohporesis has been used for the same purpose (Razin and Rottem, 1967;Razin, 1968;Rhoades et al, 1973).…”

“…They separated them into five groups, I through V, according to morphological, physiological and antigenic characteris tics; N strain was placed in group V. Kleckner (1960), in his conse cutive alphabetical designation of serotypes of avian mycoplasmas, placed the N strain in the H serotype. Further studies on characteri zation of avian mycoplasmas increased the number of reported serotypes to 12 (Yoder and Hofstad, 1964) and later to 19 (Dierks et al, 1967).…”

My.co.plas'ma. Gr. masc. n. myces a fungus; Gr. neut. n. plasma something formed or molded, a form; N.L. neut. n. Mycoplasma fungus form. Tenericutes / Mollicutes / Mycoplasmatales / Mycoplasmataceae / Mycoplasma Pleomorphic cells, 300–800 nm in diameter, varying in shape from spherical, ovoid or flask‐shaped, or twisted rods, to slender branched filaments ranging in length from 50 to 500 nm. Cells lack a cell wall and are bounded by a single plasma membrane. Gram‐stain‐negative due to the absence of a cell wall. Some have a complex internal cytoskeleton. Some have a specific tip structure that mediates attachment to host cells or other surfaces. Usually nonmotile , but gliding motility has been demonstrated in some species. Aerobic or facultatively anaerobic . Optimum growth at 37°C is common, but permissive growth temperatures range from 20 to 45°C. Chemo‐organotrophic , usually using either sugars or arginine as the major energy source. Require cholesterol or related sterols for growth. Colonies are usually less than 1 mm in diameter. The typical colony has a fried‐egg appearance . The genome size of species examined ranges from 580 kbp to about 1350 kbp . The codon UGA encodes tryptophan in all species examined. Commensals or pathogens in a wide range of vertebrate hosts. DNA G + C content ( mol %): 23–40. Type species : Mycoplasma mycoides (Borrel, Dujardin‐Beaumetz, Jeantet and Jouan 1910) Freundt 1955, 73 ( Asterococcus mycoides Borrel, Dujardin‐Beaumetz, Jeantet and Jouan 1910, 179).
