Leptospirosis is a zoonosis with a worldwide distribution, which is transmitted through direct contact with infected animals or by contact with contaminated water or soil. Objectives was to examine the presence of antibodies against 23 serogroups of Leptospira in Lagostomus maximus and Chaetopractus villosus in La Pampa province, Argentina. Ninety-four serum samples from L.

Article Synopsis
- The study focuses on cloning and sequencing a gene related to a protein that is preserved across different pathogenic serovars during infections.
- 23 pathogenic and 2 non-pathogenic serovars were analyzed, sourced from a microbiology lab in Iran, with three serovars also used in a trivalent vaccine.
- The results showed that the gene was present in all pathogenic serovars but absent in non-pathogenic ones, highlighting its potential for creating an effective recombinant vaccine due to its high conservation (95.5% to 100% similarity).

Article Synopsis
- Leptospirosis is a re-emerging infectious disease affecting humans and dogs, with the seroprevalence in pets in Italy being largely unknown.
- A study conducted in a Milan shelter evaluated 106 dogs and 51 cats for leptospiral antibodies using the microscopic agglutination test, revealing 21.7% of dogs tested positive, while no cats showed antibodies.
- Seropositivity was significantly higher in spring/summer (32.7%) compared to autumn/winter (11.1%), emphasizing the need for ongoing surveillance in shelters to address the zoonotic risks associated with this disease.

Article Synopsis
- * A study conducted from 2007 to 2021 in Spain found that 28.3% of 258 tested NHPs had antibodies indicating exposure to Leptospira spp., with the highest seropositivity observed in Hominidae species and certain wildlife centers.
- * This research represents the largest survey of Leptospira spp. in European NHPs, identifying exposure in nine species for the first time and underscoring the importance of monitoring these animals in captivity for conservation and health reasons.
