Molecular epidemiology of Leptospira spp. serogroup Sejroe associated with chronic bovine leptospirosis.

Pathogenic bacteria Leptospira spp. are commonly associated with bovine leptospirosis, characterized chiefly by chronic and subclinical reproductive disorders. Strains from the Sejroe serogroup play a significant role in these chronic genital infections known as Bovine Genital Leptospirosis (BGL), which notably impact cattle health.

Molecular Epidemiology of Pathogenic spp. Infecting Dogs in Latin America.

Canine leptospirosis is a bacterial disease caused by spirochetes of the genus . Infections can vary from asymptomatic and chronic infections to clinical acute diseases. The disease is endemic in tropical areas, such as Latin American countries, but a broad understanding of the dynamics of circulation of strains, based on molecular data, has not yet been performed.

Pinnipeds carriers of pathogenic Leptospira: New data based on molecular characterization.

Leptospirosis is a bacterial disease caused by the infection of pathogenic strains of the genus Leptospira, endemic in tropical and subtropical regions. Although well documented in terrestrial animals and humans, little information is available on its distribution and impact on marine animals. Despite clinical manifestations that may occur, the occurrence of carriers was suggested in some species.

Leptospira spp. strains associated with Bovine Genital Leptospirosis (BGL).

Bovine Genital Leptospirosis (BGL) is an important syndrome that leads to reproductive failures. The present study aimed to perform a molecular analysis of Leptospira spp. identified from genital and urine samples from in vivo naturally infected cows with poor reproductive performance.

Effect of Vaccination against on Shelter Asymptomatic Dogs Following a Long-Term Study.

(1) Background: Vaccination of dogs against leptospirosis is of paramount importance, as they ideally must provide not only long-term protection, but also against the renal carrier state of leptospires. This study assessed the post-vaccine humoral response against Leptospira in naturally exposed dogs and effects on renal carrier status. (2) Methods: A total of 118 dogs were studied for 365 days, separated into Group A (vaccinated, n = 94) and Group B (non-vaccinated, n = 24).

Bovine genital leptospirosis: Evidence of ovarian infection by Leptospira interrogans.

Leptospirosis in ruminants causes reproductive failures leading to important economic losses. This study assessed the occurrence and genetically identified Leptospira spp. in the follicular fluid (FF) of naturally infected live cows.

Persistent High Leptospiral Shedding by Asymptomatic Dogs in Endemic Areas Triggers a Serious Public Health Concern.

(1) Background: Dogs are known as hosts of and can spread this bacterium to the environment. Although Canicola is responsible for determining chronic disease in dogs, when affected by incidental serogroups such as Icterohaemorrhagiae, acute disease may occur with a predominance of clinical signs with hepatic and renal changes. In endemic areas, it is a serious public health problem.
