Mycoplasma mycoides is a bacterium that causes respiratory disease in cattle. The spelling of this word can be challenging due to the presence of the clusters of consonants "plasm" and "coides." The first part of the word, "Mycoplasma," is pronounced /maɪkəˈplæzmə/, with the stress on the second syllable. The second part, "mycoides," is pronounced /maɪˈkɔɪdiːz/, with the stress on the first syllable. The phonetic transcription helps to break down the word into its individual sounds, making it easier to spell and understand.
Mycoplasma mycoides is a species of bacteria belonging to the Mycoplasmataceae family and the Mollicutes class. It is a small, parasitic and pathogenic bacterium that lacks a cell wall, making it unique among prokaryotes. The absence of a cell wall allows Mycoplasma mycoides to be highly pleomorphic, as it can change its shape and size depending on its environment.
Mycoplasma mycoides is primarily associated with pneumonia and other respiratory diseases in animals, especially cattle, goats, and sheep. It can cause significant economic losses in livestock farming due to reduced productivity, high mortality rates, and increased susceptibility to secondary infections. In addition to the respiratory system, this bacterium can also infect various other body parts such as joints, udders, and the genital tract.
Mycoplasma mycoides is primarily transmitted through direct contact between infected and susceptible animals. It can also be spread through respiratory droplets, contaminated equipment, or vertical transmission from mother to offspring. The pathogenicity of this bacterium is dependent on various virulence factors, such as adherence molecules and toxins, which allow it to attach to and invade host cells, causing tissue damage and inflammation.
In recent years, Mycoplasma mycoides has gained significant attention due to its involvement in causing contagious bovine pleuropneumonia, a highly contagious respiratory disease in cattle. Due to its ability to cause severe respiratory diseases in both domesticated and wild animals, Mycoplasma mycoides poses a significant threat to animal health and agricultural economies worldwide.
The word "Mycoplasma" originates from the Greek words "mykes" meaning "fungus" and "plasma" meaning "formed" or "molded". This term was chosen because Mycoplasma bacteria were initially believed to be fungi due to their small size and lack of a cell wall.
The term "mycoides" is derived from the Greek word "mykēs" meaning "fungus" and the Greek suffix "-oides" meaning "resembling" or "like". Together, "mycoides" can be translated as "resembling a fungus".
Therefore, "Mycoplasma mycoides" can be understood as "molded or formed-like bacteria resembling a fungus".
