The relationship of two equine mycoplasmas to Mycoplasma mycoides.

Abstract: Two unidentified mycoplasmas, N3 and N11, isolated from the respiratory tract of horses, were found to cross-react with strains of M. mycoides subsp. mycoides in indirect immunofluorescence tests, growth-inhibition tests carried out by the running drop/agar-well method, and in complement-fixation and double immunodiffusion tests. Serologically, the equine mycoplasmas were not completely identical with any of the reference strains of M. mycoides with which they were compared. Their cultural characteristics, ability to digest coagulated serum and casein, and survival at 45 degrees C, however, suggested that they were more closely related to strains of M. mycoides subsp. mycoides, such as Y-goat, which are found in goats, than to strains of that subspecies which are pathogenic for cattle.

The research article explores the relationship between two unidentified mycoplasmas found in horses and the M. mycoides subsp. mycoides strain, which is known to cause diseases in livestock.

Research Subject and Methodology

  • The focus of the study were two unidentified mycoplasmas, referred to as N3 and N11. These microorganisms were isolated from the respiratory tract of horses and were studied for their potential interaction with M. mycoides subsp. mycoides, a bacteria often associated with livestock diseases.
  • The researchers utilized several methods to assess the relationship, including indirect immunofluorescence tests, growth-inhibition tests by the running drop/agar-well method, and double immunodiffusion tests.

Findings and Implications

  • The results revealed that these mycoplasmas cross-reacted with the M. mycoides subsp. mycoides strain. However, the equine mycoplasmas were not completely identical to any of the reference strains of M. mycoides that they were compared to, suggesting a level of differentiation.
  • Interestingly, their cultural characteristics, their ability to digest coagulated serum and casein, along with their survival at 45 degrees Celsius indicated a closer relationship to the M. mycoides subsp. mycoides strains found in goats (like the Y-goat strain), and not with those that are pathogenic for cattle.
  • This discovery has implications for understanding the diversity and behavior of mycoplasmas in different host animals. Insights drawn from this study can contribute to developing effective measures for controlling and preventing mycoplasma-related diseases in livestock, including horses and goats.
