What type of pathogens are associated with pneumonia in both humans and livestock?

Mycoplasma represents a group of microorganisms that are unique due to their lack of a cell wall, which makes them different from other types of bacteria. In both humans and livestock, Mycoplasma species, particularly Mycoplasma pneumoniae in humans and various Mycoplasma species in animals, can cause pneumonia. In livestock, certain species contribute to respiratory diseases, leading to significant health issues in species like cattle and pigs.

Mycoplasma infections are known for causing atypical pneumonia, which can be more chronic and may not always present with the classic symptoms associated with typical bacterial pneumonia. The ability of Mycoplasma pathogens to affect both humans and livestock illustrates their adaptability and the way they can exploit similar biological pathways in different hosts.

In contrast, while viruses and fungi can also cause pneumonia in humans and animals, they tend to be less commonly associated with pneumonia across both groups compared to Mycoplasma. Specific types of fungi may affect certain animals but are not universally linked with pneumonia in both humans and livestock. Mycobacteria, such as those causing tuberculosis, primarily affect humans and certain animals but are not typically classified under pneumonia caused by common pathogens across both categories. Therefore, Mycoplasma is the most fitting
