The P97 adhesin and P102 genes of Mycoplasma hyopneumoniae each have six paralogs in the genome. We tested whether these genes were expressed during infection. P102 is associated with the mycoplasma and with swine cilia. Further, most of the paralogs were transcribed in vivo in two gene transcriptional units.

UI	MeSH Term	Description	Entries
D005798	Genes, Bacterial	The functional hereditary units of BACTERIA.	Bacterial Gene,Bacterial Genes,Gene, Bacterial
D005810	Multigene Family	A set of genes descended by duplication and variation from some ancestral gene. Such genes may be clustered together on the same chromosome or dispersed on different chromosomes. Examples of multigene families include those that encode the hemoglobins, immunoglobulins, histocompatibility antigens, actins, tubulins, keratins, collagens, heat shock proteins, salivary glue proteins, chorion proteins, cuticle proteins, yolk proteins, and phaseolins, as well as histones, ribosomal RNA, and transfer RNA genes. The latter three are examples of reiterated genes, where hundreds of identical genes are present in a tandem array.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013552	Swine	Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).

D045705	Mycoplasma hyopneumoniae	A species of gram-negative bacteria that causes MYCOPLASMA PNEUMONIA OF SWINE. The organism damages the CILIA in the airways of the pig, and thus compromises one of the most effective mechanical barriers against invading pathogens. The resulting weakening of the IMMUNE SYSTEM can encourage secondary infections, leading to porcine respiratory disease complex.
D045729	Pneumonia of Swine, Mycoplasmal	A chronic, clinically mild, infectious pneumonia of PIGS caused by MYCOPLASMA HYOPNEUMONIAE. Ninety percent of swine herds worldwide are infected with this economically costly disease that primarily affects animals aged two to six months old. The disease can be associated with porcine respiratory disease complex. PASTEURELLA MULTOCIDA is often found as a secondary infection.

D018829	Adhesins, Bacterial	Cell-surface components or appendages of bacteria that facilitate adhesion (BACTERIAL ADHESION) to other cells or to inanimate surfaces. Most fimbriae (FIMBRIAE, BACTERIAL) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. What is sometimes called polymeric adhesin (BIOFILMS) is distinct from protein adhesin.
