Bordetella avium 197N

Names Bordetella avium 197N
Accession numbers NC_010645
Background Bordetella avium is a Gram-negative aerobic bacterium that causes bordetellosis in birds. Bordetella avium (strain 197N) is a spontaneous nalidixic acid-resistant derivative of virulent strain 197. Bordetella avium (strain 197N) was isolated from a diseased turkey in a commercial flock in the early 1980's. It was commonly thought to infect mostly commercially grown turkeys but it is also found in a variety of healthy wild and domesticated birds. Bordetellosis is highly contagious producing an upper respiratory tract infection that most often leads to death in chicks. The bacterium is easily transmitted by aerosols, leading to a rapid spread of the disease in facilities where birds are housed closely together. With 3417 predicted coding sequences, B.avium (strain 197N) has the smallest genome and gene complement of the sequenced bordetellae. Over 1100 genes present in B.avium but not in B.bronchiseptica were identified. It includes a unique fimbrial gene cluster, two hemagglutinins and their cognate secretion accessory proteins, a type II secretion system, an LPS biosynthesis locus, two separate loci potentially involved in the biosynthesis of an LPS O antigen, an operon that seems to encode enzymes for the synthesis of a cellulose-like polysaccharide and three prophages. There are 68 pseudogenes in B.avium. Bordetella avium appears to have a complete and intact set of motility and chemotaxis genes. Motility appears to be completely shut off above 40 degrees Celsius, which is close to the body temperatures of turkeys. (EBI Integr8)
