“…The prevalence of Leptospira Icterohaemorrhagiae varies across different animal species. While the bacteria may be more commonly found in pigs than in cattle or horses in some cases, the situation may be reversed in other regions or rearing conditions (Ellis, 2010;Langoni et al 2004;Yatbantoong et al, 2019).Our findings shown a significance for this serovar, being the more found serovar with prevalence rate of 17.99% present in 26.15% of properties. In certain regions, the prevalence of Leptospira Pomona, among other species, may exceed that of Leptospira Icterohaemorrhagiae, leading to a greater number of leptospirosis cases in pigs, cattle, and horses (Ellis, 2010;Smith et al 2015;Aragão, 2021).…”

Leptospirosis is a zoonotic disease that poses a significant threat to human and animal health worldwide. Among different animal species, pigs are known to play a crucial role in the transmission of the pathogenic Leptospira spp. This study aimed to investigate the prevalence of Leptospira spp. infection and associated risk factors in subsistence pig production in the state of Paraná, Brazil. A total of 1393 serum samples were collected from pigs on 188 subsistence properties in different regions of the state, and tested using the microscopic agglutination test (MAT) to detect antibodies against 24 different Leptospira spp serovars. The results revealed an overall seroprevalence of 68.78% for Leptospira spp. antibodies, with Icterohaemorrhagiae, Butembo, and Pomona being the most commonly detected serovars. Poor housing conditions, lack of rodent control, absence of veterinary assistance, and a history of reproductive problems were identified as significant risk factors associated with Leptospira spp. infection in the subsistence pig population. These findings highlight the urgent need for implementing effective control measures, such as improved housing conditions, rodent control, and veterinary assistance, to prevent the spread of this zoonotic disease in subsistence pig production systems in Paraná, Brazil.

The diagnosis of leptospirosis commonly relies on serology, which has three issues that are referred: the sampling, the antigen panel, and the cutoff point. We propose a systematic review of the bovine leptospirosis in Latin America, in order to provide a better understanding of the evolution of the research and of the seroepidemiology of bovine leptospirosis in that region. Internet databases were consulted over the year of 2014. Inclusion criteria for analysis included serosurvey using microscopic agglutination test (MAT), a relevant number of animals, the presence in the antigen panel of at least one representant of serogroup Sejroe, and a cutoff point of ≥100. A total of 242 articles that referred to cattle, leptospir*, and one region of Latin America was found. Only 105 articles regarding to serosurveys using MAT were found in several countries, and 61 (58.1 %) met all the inclusion criteria. In conclusion, this systematic review demonstrated a high prevalence of the infection (75.0 % at herd level and 44.2 % at animal level), with predominance of strains of serogroup Sejroe (80.3 %). It was evident that there is the necessity of more studies in several countries, as well as the need for greater standardization in studies, especially with regard to the adopted cutoff point at serological tests.
