*MST, multispacer sequence typing; Ct, cycle threshold; BAL, bronchoalveolar lavage; NA, not applicable.
†MST genotypes were identified by using the MST database (http://ifr48.timone.univ-mrs.fr/MST_Coxiella/mst).
‡Result obtained by using improved amplification primers for Cox57 (9).
§ –, no result was obtained. The lack of results may be explained by the significantly larger PCR product that is targeted, low quantity of DNA or to overall poor performance of the PCR amplification.
¶This combination of 4 alleles has not been observed and justifies the assignment of a new MST genotype.
