Identification of Pathogenic Leptospira Serogroups in Domestic Dogs

Identification of Pathogenic Leptospira Serogroups in Domestic Dogs

Leptospirosis is an important bacterial zoonosis worldwide. Dogs and other animals can be infected, constituting an important role in the spread of the bacteria to humans. The infection is caused by any of the pathogenic serovars of the 25 serogroups of Leptospira spp. The aim of this study was to identify serogroups of Leptospira spp in dogs that had presumptive diagnosis of leptospirosis. A total of 305 serum samples were obtained from dogs in 31 districts of Lima. The microagglutination test (MAT) was performed, establishing > 1/100 seroreactivity titre as seropositive using reference strains of the 25 serogroups, including the new Iquitos serogroup, Varillal serovar, strain Var10, isolated and reported in human cases in Peru. The frequency of seropositive samples was 58.0% and 10.2% were co-agglutinations. The seropositive reacted against 18 serogroups and the most frequent were: Iquitos (15.1%), Tarassovi (12.1%), Canicola (12.1%), Australis (4.6%), Icterohaemorrhagiae (4.3%), Pomona (3.9%), Mini (3.3%) and Ballum (2.6%). There were no seroreactors to serogroups Bataviae, Celledoni, Hebdomadis, Lousiana, Panama, Ranarum, and Sarmin.

Los perros y otros animales pueden infectarse, constituyendo un factor importante en la diseminación de la bacteria al humano. La infección es causada por cualquiera de los serovares patógenos de los 25 serogrupos de Leptospira spp. El estudio tuvo como objetivo identificar serogrupos de Leptospira spp presentes en perros con diagnóstico clínico presuntivo de leptospirosis de la ciudad de Lima. Se obtuvieron 305 muestras de suero sanguíneo de perros de 31 distritos de Lima Metropolitana. Se realizó la prueba de microaglutinación (MAT), estableciéndose títulos ≥1/100 de serorreactividad como seropositivos. Se utilizaron cepas de referencia de los 25 serogrupos, incluyendo al nuevo serogrupo Iquitos, serovar varillal, cepa VAR10, aislado y reportado en casos humanos en Perú. Se detectaron 177 seropositivos (58.0%), 31 (10.2%) de los cuales fueron coaglutinaciones. Los serogrupos reaccionaron contra 18 serogrupos siendo los de mayor frecuencia: Iquitos (15.1%), Tarassovi (12.1%), Canicola (12.1%), Australis (4.6%), Icterohaemorrhagiae (4.3%), Pomona (3.9%), Mini (3.3%) y Ballum (2.6%). No se identificaron serorreactores en los serugrupos Bataviae, Celledoni, Hebdomadis, Lousiana, Panama, Ranarum y Sarmin.
