A total of 100 non-lactating multiparous females (87 healthy and 13 metritic) were examined.

Gene expression analysis showed significant upregulation of\n                      <jats:italic>CARD9, SIGLEC1, VSIG4, BTRC, SLC2A3, ACOD1<\/jats:italic>\n                      , and\n                      <jats:italic>PFKFB3<\/jats:italic>\n                      , alongside downregulation of\n                      <jats:italic>CPT1A, ATF4, GADD45B, SLC7A11<\/jats:italic>\n                      , and\n                      <jats:italic>PRDX3<\/jats:italic>\n                      . Sequencing identified 19 SNPs, with significant differences in genotype distribution between groups, and discriminant analysis achieved complete classification accuracy. Hematological findings included normocytic normochromic anemia, leukocytosis, neutrophilia, lymphopenia, and monocytosis. Biochemically, metritic camels showed hypoglycemia and decreased levels of estrogen, progesterone, FSH, LH, T4, calcium, and antioxidant markers (GSH, CAT, and TAC), while NEFA, BHBA, cortisol, MDA, and pro-inflammatory cytokines (IL1\u03b1, IL1\u03b2, IL6, IL10, and TNF\u03b1) were significantly elevated.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Overall, clinical metritis in dromedary camels was associated with significant hematological, metabolic, hormonal, oxidative, immunological, and genetic alterations. These findings identify a panel of reproductive and molecular biomarkers that may serve as promising candidate biomarkers associated with clinical metritis. However, given the observational nature of the study and the relatively small number of metritic she-camels, these findings should be interpreted with caution and require validation in larger, independent camel populations before their diagnostic, prognostic, or breeding applications can be established.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fvets.2026.1890020","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T04:39:41Z","timestamp":1784695181000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Identification of reproductive and molecular biomarkers associated with clinical metritis in dromedary camels (Camelus dromedarius)"],"prefix":"10.3389","volume":"13","author":[{"given":"Haifa Ali","family":"Alqhtani","sequence":"first","affiliation":[{"name":"Department of Biology, College of Science, Princess Nourah bint Abdulrahman University","place":["Riyadh, Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed A.","family":"Elsayed","sequence":"additional","affiliation":[{"name":"Department of Animal and Poultry Nutrition, Desert Research Center","place":["Cairo, Egypt"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tahani M.
