Samples were examined using microscopy (modified Ziehl\u2013Neelsen stain), and all were subsequently analyzed using a nested PCR assay targeting the\n                      <jats:italic>gp60<\/jats:italic>\n                      gene for species and subtype identification.

One case was found in a patient with leukemia (one out of 34; 2.9%), and another in a patient with lymphoma (one out of 21; 4.8%). The difference in prevalence between these groups was not statistically significant.
