''Neisseria elongata''
''Genus species''
 
<i>Neisseria elongata</i>, formerly known as Centers for Disease Control (CDC) group M6, was described by Bovre and Holten in 1970 as a gram-negative, rod-shaped bacterium of the family Neisseriaceae, where it is found in the oral bacterial flora of the human pharynx and throat or in the blood of those infected (2). <i>N. elongata</i> consists of three subspecies, <i>N. elongata</i> subsp. <i>elongata,</i> <i>N. elongata</i> subsp. <i>glycolytica,</i> and <i>N. elongata</i> subsp. <i>nitroreducens,</i> in which are separated based on their biochemical differences (3). Although these subspecies of <i>N. elongata</i> were previously believed to be nonpathogenic to humans, recent case studies from patients suffering from endocarditis, have indicated that all three <i>N. elongata</i> subspecies are associated with human disease, particularly endocarditis and osteomyelitis (2).


Although the <i>N. elongata</i> genome has not yet been sequenced, the importance of sequencing its genome will provide information on the three <i>N. elongata</i> subspecies that could possibly assist in distinguishing their pathogenic roles in endocarditis and osteomyelitis. Before the pathogenic roles of all three <i>N. elongata</i> subspecies discovered, as <i>N. elongata</i> subsp. <i>nitroreducens</i> was the first subspecies to be discovered as pathogenic, <i>N. elongata</i> subsp. <i>elongata</i> and <i>N. elongata</i> subsp. <i>glycolytica</i> were considered just to be transient colonizers of the human upper respiratory tract and urogentical tract (3). Thus, the sequencing of their genomes could possibly provide further insight into the differences and similarities involved in the factors influencing the metabolism and virulent features of the three <i>N. elongata</i> subspecies.
