Pleuropneumonialike organism, also known as Mycoplasma spp., is a group of bacteria that cause respiratory infections in animals and humans. There are various synonyms for this term, such as mycoplasmosis, contagious bovine pleuropneumonia, and walking pneumonia. Mycoplasmosis refers to any disease caused by Mycoplasma spp., not just respiratory infections. Contagious bovine pleuropneumonia primarily affects cattle and is caused by Mycoplasma mycoides subsp. mycoides. Walking pneumonia is a mild form of pneumonia caused by Mycoplasma pneumoniae that doesn't always require bedrest. In summary, there are multiple ways to describe pleuropneumonialike organisms depending on the specific type of infection and the affected species.
