The BK virus is a member of the polyomavirus family. Past infection with the BK virus is widespread, but significant consequences of infection are uncommon, with the exception of the immunocompromised and the immunosuppressed. BK virus is an abbreviation of the name of the first patient whom the virus was isolated from in 1971 (the patient was

Different JCPyV subtypes differ in the virulence with which t BK Polyomavirus in Solid Organ Transplantation Screening † q1 - 3 months or † if allograft dysfunction † if allograft biopsy negative BKV viremia positive positive † Plasma BKV load >4 log 10 cp/mL or equivalent Reduce Immunosuppression Comments Testing options: † Urine cytology (decoy cells) or †BKV viruria Urine EM (PyV aggregates) or Polyomavirus-associated (BK virus) nephropathy (BKVAN) arises in 1–8% of renal allografts, with an associated risk of graft damage or even graft loss. In the early post-renal transplant months, BKVAN is a key differential diagnostic consideration significantly overlapping with acute rejection.

Fluorescent signal acquisition for each fluorophore was performed consecutively during the same reaction. Figure 1 Polyomavirus-Haufen were counted in 40 urine samples from patients with biopsy-proven definitive PVN. The number of PV-Haufen was correlated with both histologic PVN disease grades 1 to 3 and the number of SV40-T–expressing cells as indicators of intrarenal PV replication in corresponding renal allograft biopsies (manual counts and automated morphometry).

Consequently, urine that is collected for fertilizer production often has high concentrations of polyomavirus genes. Urine cytology is technically the simplest method to monitor polyomavirus infection after transplantation. Transient shedding of virus-infected cells can be seen in acute cellular rejection, tacrolimus nephrotoxicity, and acute tubular necrosis. A morphologic sign of the (re) activation of polyomaviruses is the detection of typical intranuclear viral inclusion bearing epithelial cells, so-called “decoy cells”, in the urine.

Polyoma Virus1– As stated, the BK virus is a member of polyomavirus family. Latent Form- The BK Polyomavirus is not known to cause any significant infection and is usually a latent form of virus. Dormant Virus- The virus inhabits as a dormant virus in the tissue of kidney and urinary tract for the rest of the life of the individual.

Decoy cells often contain polyoma-BK-viruses. The inclusion bearing cells are easily identified and quantifiable in routine Papanicolaou stained urine cytology specimens.
