The proportion of positive Leptospira microscopic agglutination tests for 23,005 dogs significantly increased from 2002 to 2004 (p < 0.002) regardless of the positive cutoff titer used and was highest (p < 0.05) for serovars Autumnalis and Grippotyphosa. The strongest positive serologic correlation (r = 0.72) was between serovars Autumnalis and Pomona.

Article Synopsis
- Leptospirosis, a re-emerging disease affecting both humans and dogs, was diagnosed in a study of 210 suspected dogs using MAT and PCR tests.
- The study found that 58.57% of the dogs had anti-leptospiral antibodies, with 23.33% confirmed as acutely infected, primarily influenced by factors like age, seasonal weather, outdoor exposure, and contact with rodents or wet environments.
- The identification of Leptospira interrogans in infected dogs highlights the importance of recognizing these risk factors for timely treatment and recovery strategies in canines.
Article Synopsis
- The study characterized the genome of a Colombian strain of a bacterium to identify its virulence factors.
- The researchers sequenced the strain using advanced technology and utilized bioinformatics tools for genome analysis, including gene count and protein prediction.
- Findings revealed that the isolate has 4,138 proteins, with 141 unique to its genome, and identified possible virulence factors, enhancing the understanding of the bacteria's pathogenic mechanisms.
Acute leptospirosis in horses: A retrospective study of 11 cases (2015-2023).

Article Synopsis
- Limited reports on leptospirosis in horses prompted a study of 11 cases from 2015 to 2023, focusing on clinical signs and diagnostic methods.
- Common symptoms observed included lethargy, anorexia, fever, and acute kidney injury, with several horses also showing signs of pulmonary and liver disease.
- The study emphasizes that leptospirosis should be a key consideration in horses displaying acute systemic inflammation, urging the use of both serology and urine PCR for accurate diagnosis.
