Detection of P1 and P2 Subclades of Leptospira carriage in swine in Sri Lanka
This study demonstrates that swine reared for human consumption in Sri Lanka serve as an important reservoir of Leptospira spp. All pigs sampled were clinically healthy at ante-mortem inspection, confirming their role as asymptomatic carriers of Leptospira spp. The detection of strains identical to those previously reported in human infections suggests a potential zoonotic threat exacerbated by inadequate farm hygiene and environmental contamination. These findings highlight the need for comprehensive research from a One Health perspective to gain a deeper understanding of the epidemiology of leptospirosis in Sri Lanka.
