  • HPV-based screening therefore provides an opportunity to circumvent this by enabling a community-based, self-sampling approach to screening and reaching more women in the privacy of their homes. (who.int)
  • Of the four total positive stool samples, all yielded Salmonella serotype Montevideo isolates with indistinguishable PFGE DNA patterns. (cdc.gov)
  • We compiled records on macacine herpesvirus 1 (McHV-1) seroprevalence and, during 2015-2016, collected saliva and fecal samples from the free-ranging rhesus macaques of Silver Springs State Park, a popular public park in central Florida, USA, to determine viral DNA shedding and perform sequencing. (cdc.gov)
  • In the laboratory setting, ≈40% of seropositive rhesus macaques had viral DNA in the trigeminal ganglia, indicating these animals were carriers of the virus and capable of reactivation ( 8 ). (cdc.gov)
