Background And Aim: is one of the main pathogens responsible for veterinary and human infections, and it is associated with significant economic losses in the livestock, as it causes severe diseases to humans, particularly in children. For that reason, there is a need for introducing new drugs to treat diseases. The Brazilian species richness is a source of potential new antibacterial natural products.

Methods: 24 adult susceptible female BALB/c mice were inoculated with E coli - UPEC O4:K-:H5 by a transurethral catheter. Cantharis 6cH or vehicle (placebo) was offered to mice by free access into the drinking water (1:100), during 24 h after infection.

- * Rectal swabs from 36 wild mammals were collected for bacterial isolation; results indicated higher virulence and antimicrobial resistance in E. coli strains from the more human-influenced Cantareira State Park compared to the more natural Santa Isabel do Rio Negro Region.
- * Two Salmonella enterica strains linked to reptiles were found only in the Amazon region and were susceptible to all tested antimicrobials, suggesting a need for further research on the environmental health implications of these pathogens in wildlife.
Article Synopsis
- The study examined captive wild felids in Brazil, testing 159 neotropic and 51 exotic cats for infectious pathogens using blood tests.
- Frequent antibodies were found for Feline parvovirus, Feline coronavirus, Feline calicivirus, and Bartonella spp., while Felid herpesvirus 1 and hemotropic mycoplasmas were less common.
- Serologic evidence for more serious infections like Feline leukemia virus was rare, highlighting the need for health assessments before relocating these animals.
