Mycoplasma hyopneumoniae is a type of bacteria that has a small genome and does not contain a cell wall. It is found throughout respiratory systems in pigs, such as in the cilia of cells in lungs, and causes coughs and more specifically, enzootic pneumonia (EP). EP is known to cause weight loss in pigs, leading to millions of dollars of losses in the livestock industry.
It is important to sequence the genome of Mycoplasma hyopneumoniae in order to analyze how much the bacteria is involved in respiratory diseases in pigs and to also detect antibodies against the bacteria.
The strains of Mycoplasma hyopneumoniae are collected using nasal swabs or lung sections. The organisms are then isolated in cultures. However, growth of Mycoplasma hyopneumoniae is fairly difficult in the laboratory as the bacteria grows very slowly and requires specific nutrients. Enzyme-linked immunosorbent assay (ELISA) and nested PCD (nPCR) are used together for the detection of the bacteria as well as determination of antibodies against the bacteria. After detecting strains, it is important to analyze how much vaccination affected these strains.

Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
The genome reveals factors mediating coaggregation, cell signaling, and stress protection. It has a spiral shape and is arranged in singles. It is a mobile organism but does not contain any endospores. Motility is by rapid rotation around the long axis, flexation of the cell and locomotion along a helical path. The most distinctive property is the presence of periplasmic flagella wound around the helical protoplasmic cylinder and encased in an outer sheath.
