¹From the beginning of 2006, identification of the isolates did not include biochemical tests any more. Five M. celatum isolates from the period 2002–2005, on which biochemical tests were performed, displayed uniform biochemical characteristics shown in this table.
²TCH: thiophene 2-carboxylic hydrazide.
