Mycoplasmas and bovine respiratory disease: studies related to pathogenicity and the immune response--a selective review.
Three species of mycoplasma have been established as being of importance as causes of pneumonia in housed calves, based on pathogenicity studies and frequency of association with the disease. These three species are Mycoplasma bovis, M. dispar, and Ureaplasma diversum. M. bovis is the most pathogenic of these species but the disease outbreaks with which it is associated are sporadic. M. dispar ...
متن کاملMycoplasmas: sophisticated, reemerging, and burdened by their notoriety.
Mycoplasmas are most unusual self-replicating bacteria, possessing very small genomes, lacking cell wall components, requiring cholesterol for membrane function and growth, using UGA codon for tryptophan, passing through "bacterial-retaining" filters, and displaying genetic economy that requires a strict dependence on the host for nutrients and refuge. In addition, many of the mycoplasmas patho...
متن کاملDermatophytes: Their taxonomy, ecology and pathogenicity
structures with typical arrangement on hyphae, chlamydospores, spirals, antler-shaped hyphae (chandeliers), nodular organs, pectinate organs and racquet hyphae [2,4]. In addition, some physiological characteristics based on nutritional requirements [4-8]such as vitamin deficiency can be used to identify some dermatophytes. Most dermatophyte colonies develop forms and pigmentation which can allo...
متن کاملA phylogenetic analysis of the mycoplasmas: basis for their classification.
Small-subunit rRNA sequences were determined for almost 50 species of mycoplasmas and their walled relatives, providing the basis for a phylogenetic systematic analysis of these organisms. Five groups of mycoplasmas per se were recognized (provisional names are given): the hominis group (which included species such as Mycoplasma hominis, Mycoplasma lipophilum, Mycoplasma pulmonis, and Mycoplasm...
متن کاملMycoplasmas and arthritis.
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...
