Occurrence of the European Subgroup of Subtype I BK Polyomavirus in Japanese-Americans Suggests Transmission outside the Family
Keyword(s):
ABSTRACT To examine the mode of transmission of BK polyomavirus (BKV), urine samples were collected from Japanese-Americans in Los Angeles and from other southern Californians. Subtype I was the main subtype found in samples from both groups. The subtype I subgroup Ib-2, which is predominant in Europe, was the primary subgroup detected in second-generation Japanese-Americans and in southern Californians; however, the Ic subgroup prevalent in native Japanese was rare in these populations. Since the European subgroup (Ib-2) predominated in the studied geographic area, the findings demonstrate that transmission outside the family is common in the spread of BKV, unlike previous findings for JC polyomavirus.
