Seventy-seven cattle with BLV-antibody (19.25%) and 77 without the antibody were used. No significant difference was found between O.D. of sera of PL + (Persistent Lymphocytosis Positive) and PL-(Negative) cattle. The mean O.D. of urine samples of 77 seropositive cattle was significantly higher than that of 77 seronegative cattle (P < 0.01). There were also differences between urine O.D.s of seropositive (PL +) and seropositive (PL-) groups of cattle with IP (P < 0.05) and SB (P < 0.01) kits. All the results revealed the presence of BLV-antibody in the urine of the cattle without any urinary dysfunction.eninfo:eu-repo/semantics/openAccessBiotechnology & applied microbiologyMicrobiologyDiagnosisInfectionLeukosisSamplesHIV-1MilkAnimalsAntibodies, viralCattleEnzootic bovine leukosisEnzyme-linked immunosorbent assayImmunoglobulin GLeukemia virus, bovineArticle0000809057000022-s2.0-003300051241641828610389255Biotechnology & applied microbiologyMicrobiologyBovine Leukemia Virus; Enzootic Bovine Leukosis; DeltaretrovirusImmunoglobulin g antibodyVirus antibodyArticleBlood analysisBovine leukemia virusEnzyme immunoassayEnzyme linked immunosorbent assayNonhumanUrinalysis
