Mycoplasma species, which can cause upper respiratory tract disease (URTD), are significant pathogens of birds, mammals, fish, and reptiles. Mycoplasmosis is of high concern for chelonian conservation, with the most well-documented cases in gopher and desert tortoises. Mycoplasma sp. infections have been reported in captive and free-living box turtles ( Terrapene spp.). We documented URTD assoc...

Bovine mycoplasmosis due to Mycoplasma bovis causes several important bovine diseases such as pneumonia, mastitis, arthritis, otitis, genital disorders or keratoconjunctivitis. Variable surface lipoproteins, adhesion, invasion of host cells, modulation of the host immune system, biofilm formation and the release of secondary metabolites like hydrogen peroxide, as well as synergistic infections ...

The causes of the deaths or culling of 155 adult pheasants in breeding pens on one site between 1995 and 1997 were investigated. Approximately half the deaths were the result of problems associated with the reproductive tract or trauma, including injuries acquired during fighting or mating. Sinusitis was the commonest infectious cause of mortality or culling, despite medication of the flocks fo...

Mycoplasmas were isolated from chickens with respiratory problems during field investigations of a concentrated respiratory disease outbreak in western Cuba, 1997. A high percentage of mycoplasma cultures from tracheas and air-sac lesions yielded pure cultures of Mycoplasma pullorum. The aim of the present work was to investigate the heterogeneity among M. pullorum isolates from Cuba and strain...

Efforts in the United States to control Mycoplasma gallisepticum (MG) began in the 1960’s, primarily as a response to high condemnations from airsacculitis after the initiation of USDA post mortem inspection of poultry. Somewhat later, M. synoviae (MS) and M. meleagridis (MM) were added to the program. Since then, significant progress has been made in controlling Mycoplasma infections in turkey...
