Abstract:
The carriage of pathogenic Leptospira was investigated by PCR in 51 wild carnivores, 20 domestic dogs with outdoor access, and 27 free-roaming domestic cats sampled in periurban Barcelona (NE Spain). Overall prevalence was 7.7%, with DNA confirmed in 3/30 common genets (Genetta genetta) (serovars Icterohaemorraghiae and Sejröe), 1/9 red foxes (Vulpes vulpes) (Canicola) and 2/27 cats (Icterohaemorraghiae). Though most of the dogs were vaccinated against Leptospira, DNA of the serovar Canicola was detected in the urine of 25% of the vaccinated animals, and the serovar Icterohaemorraghiae in one non-vaccinated dog.

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
