An enzyme-linked immunosorbent assay (ELISA) based on the recombinant p23 of Cryptosporidium parvum was established for the detection of antibodies against C. parvum in cattle. The sensitivity and specificity of the ELISA were evaluated with the standard indirect fluorescent antibody test (IFAT) using sporozoites as antigens. Of 77 bovine sera collected from China, 20 (26.0%) were identified as positive by the IFAT. The same samples were tested with the ELISA. The optical densities at 415 nm were compared to the IFAT results and statistically analyzed to designate a provisional cut-off point. As a result, the cut-off point was concluded to be 0.08, which was considered to be the best condition in the light of its sensitivity (80%) and specificity (73.7%)....

From previous cDNA subtraction studies analyzing gene expression in equine endometrium, high lipocalin 2 (LCN2) mRNA expression was found in the gravid endometrium. In the uterus, LCN2 may transport hydrophobic molecules and siderophores with iron, or may form a complex with another protein, however, the expression of uterine LCN2 beyond day 20 of equine pregnancy and its receptor has not been characterized. To study the expression and potential roles of uterine LCN2 from pre-implantation to mid-gestation period, stage-specific endometrial samples were obtained from day 13 (day 0 = ovulation) cyclic and days 13, 19, 25, and 60 to 131 pregnant mares. Expression of LCN2 mRNA increased in day 19 gravid endometrium and was abundant from day 60 onward. The...
