Resumo
There is little information about the presence of
human adenovirus (HAdV) in drinking water in Neotropical
regions. Thus, the present study sought to conduct
quantification and molecular characterization of HAdVs
detected in treated water samples from an area of the
Cerrado ecoregion of Brazil. Between August and
November 2012, samples were collected from four treated
water reservoirs and their respective sites along the water
distribution network of the city of Goiaˆnia, for a total of 80
samples. All samples were concentrated and analyzed by
qPCR, and selected samples were sequenced. Overall, 76.6
(100–109 GC mL-1) and 37.5 % (101–108 GC mL-1) of samples drawn from reservoirs and their distribution sites,
respectively, were positive for virus by qPCR. All samples
selected for sequencing were characterized as species C
human adenovirus. Such high HAdV counts have in treated
water samples. This finding merits special attention, particularly
from the sanitation authorities, because the high
number of GC mL-1 may be an indicative of risk to human
health.
