Heterogeneity of Mycoplasma Dispar

Serological heterogeneity of Mycoplasma pulmonis.

Susceptibilities of Mycoplasma bovis, Mycoplasma dispar, and Ureaplasma diversum strains to antimicrobial agents in vitro.

The purpose of this study was to determine the susceptibility of various strains of Mycoplasma bovis, Mycoplasma dispar, and Ureaplasma diversum, which are prevalent causes of pneumonia in calves, to 16 antimicrobial agents in vitro. The MICs of the antimicrobial agents were determined by a serial broth dilution method for 16 field strains and the type strain of M. bovis, for 19 field strains a...

Heterogeneity among strains of Mycoplasma granularum and identification of Mycoplasma hyosynoviae, sp. n.

Twelve filtrable, pleomorphic organisms isolated from swine joints and respiratory tracts had typical colonial and microscopic characteristics of mycoplasmas. They resisted penicillin and did not revert to cell wall-producing bacterial forms in media devoid of bacterial inhibitors. The morphological and growth characteristics of these mycoplasmas were similar to those described previously for M...

EntaMoeba disPar lnfections

Eleitamoeba histolytica is now known to consist of two genetically distinct yet morphologically identical species, the invasive pa・rasite, retaining the name Entamoeba histolvtica Schaudinn, 1903, separating it from the noninvasive parasite, Entamoeba disPar Brumpt, 1925 [1]. In view of.this recent development in amebiasis research, there is a great need to reassess preyiously reported prevalen...

HETEROGENEITY OF MACROPHAGE POPULATIONS: ANTIBODIES DETECTING VARIOUS POPULATIONS OF MACROPHAGES

Two groups of antibodies against mouse resident alveolar and peritoneal macrophages have been raised individually in rabbits by immunization with whole cell suspensions of lavaged alveolar and peritoneal macrophages. The whole antisera reacted positively with neutrophils and lymphocytes. However, upon extensive absorptions with these cells the activity became restricted to macrophages. The...
