AB HIV-1 positive patients from Tanzanian villages near Shirati were
examined for urinary excretion of the human polyomaviruses JC and BK
using the polymerase chain reaction (PCR). BK virus (BKV) was detected
in 11 of 23 individuals tested. The BKV DNA sequences were all closely
related to prototype Gardner strain and BKV (DUN). In contrast, a new
type of JCV, termed Type 3 [or JCV (Shi)], was identified in seven of
these same 23 individuals by comparison with Type 1 and Type 2 sequences
of the VP1/intergenic/T antigen region of U.S., European and Asian
strains. This suggests that JCV and BKV, although closely related, have
different evolutionary histories within the African population. The six
BKV regulatory regions amplified all showed the archetypal
configuration. However, two of the seven JCV regulatory regions showed
rearrangements: a small deletion and an inverted repeat. JCV causes a
fatal demyelinating disease, progressive multifocal leukoencephalopathy
(PML), in about 5% of AIDS patients in Europe and the U.S.A., but only
one case has been reported in Africa. Our results suggest that this
rarity of PML is not due to the absence of JCV in the African
population.
