Now looking at the human leptospirosis landscape on CCL5/RANTES, low levels of serologic CCL5/RANTES were found in patients with fatal leptospirosis [30] and CCL5/RANTES was the most increased chemokine found in serum of patients diagnosed with non-lethal leptospirosis associated with L. interrogans serovars Copenhageni and Icteroheamorrhagiae [31]. The gene discussed is CCL5; the disease is leptospirosis.
