title: Prevalence of parvovirus in Minnesota turkeys.
abstract: Poult enteritis syndrome (PES) is characterized by enteritis and decreased body weight gain in growing turkey poults between one d and 7 wk of age. Another syndrome called light turkey syndrome (LTS) causes a decrease in body weight of adult tom turkeys in Minnesota leading to huge economic losses. Reovirus, rotavirus, and astrovirus have been found in LTS and PES flocks in Minnesota. We tested 80 fecal pools collected from four LTS flocks and 35 fecal pools from non-LTS flocks for the presence of parvovirus. In addition, 116 fecal and meconium samples from turkeys submitted to the Minnesota Veterinary Diagnostic Laboratory (MVDL) also were tested. The samples were tested by PCR using primers for the non-structural 1 (NS1) gene of parvovirus. Of the 80 samples from LTS flocks, 41 were positive for parvovirus while 20 of 35 samples from non-LTS flocks were positive. The prevalence of parvovirus in fecal samples submitted to MVDL was relatively low; only five of the 116 pools were positive. The partial NS1 gene sequences from LTS and non-LTS samples showed 98 to 100% nt identity except for one divergent turkey parvovirus (TuPV) strain that revealed 90% identity and clustered with chicken-like parvoviruses. The presence of this divergent strain suggests circulation of a recombinant strain of TuPV in Minnesota turkeys. Our results indicate that TuPVs are circulating in both LTS and non-LTS flocks of turkeys in Minnesota, and further experimental studies are indicated to study the role of TuPV in LTS.
