Alcaligenaceae De Ley et al. 1986
General information
Description and emendation
Rods or coccobacilli 0.2 to 1.0 μm in diameter and 0.5 to 2.6 μm long, occurring singly, in pairs, or rarely in chains. Gram-negative. No resting stages are known. Motile by peritrichous flagella or nonmotile (Bordetella parapertussis and Bordetella pertussis). Aerobic, having a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor. Some strains can use nitrate or nitrite as an alternative electron acceptor, allowing growth to occur anaerobically. Optimum temperature, 30 to 37°C. Colonies are usually non-pigmented. Most species are oxidase and catalase positive. Alkaline reaction in litmus milk. Gelatin not hydrolyzed. Chemoorganotrophic. Most species utilize a variety of organic acids and amino acids as carbon sources. Carbohydrates are usually not utilized. Some strains produce acid from D-glucose and D-xylose and utilize both of these carbohydrates as carbon sources. Some species require nicotinamide, organic sulfur (e.g., cysteine), and organic nitrogen (amino acids). Species of the genus Alcaligenes occur in soil, water, the hospital environment, and human clinical material. Species of the genus Bordetella localize and multiply among the epithelial cilia of the respiratory tract and are pathogenic for warm-blooded animals. DNA-rRNA hybridization studies have shown that all of the species of the family are closely related, because they link at an average Tm(e) value of at least 75.5°C. The G+C content of the DNA is 56 to 70 mol%.
