Article Synopsis
  • The study explored the genetic diversity of Bartonella species in 79 cats from Chile, focusing on their blood samples that tested positive for Bartonella spp. using qPCR.
  • DNA sequencing and phylogenetic analysis revealed that most samples matched Bartonella henselae, with a smaller number showing similarities to Bartonella koehlerae.
  • Notably, the research identified multiple haplotypes in individual cats, marking the first report of co-infection by different variants of B. henselae and B. koehlerae in Chilean cats.

As part of a larger study on carried by wild birds in the city of Valdivia (southern Chile), two curved rod-shaped Gram-stain-negative strains (A82 and WB-40) were recovered from faecal samples and subjected to a taxonomic study. Results of a genus-specific PCR showed that these isolates belonged to the genus . Further identification by 16S rRNA and (60 kDa heat-shock protein) gene sequence analysis revealed that they formed a separate phylogenetic clade, different from other known species with '' CNRCH 2005/566H and WBE14 being the most closely related species.

The aim of this study was to demonstrate the noninferiority of a novel teat disinfectant based on copper and zinc (ZkinCu; Copper Andino, Santiago de Chile, Chile) compared with a previously proven glycolic acid active disinfectant (OceanBlu; DeLaval, Kansas City, MO) as a positive control, with respect to the incidence of new intramammary infections under natural challenge conditions on a commercial robotic dairy farm. This study was conducted in 6 robotic pens of approximately 60 milking cows each. The pens were randomly assigned to 1 of the 2 studied disinfectants.

In October 2004, 41 goats > 2 years old from a Saanen dairy goat herd located in Purranque County, 10th Region, Chile, were sampled and tested for paratuberculosis. While collecting samples it was observed that several goats were thin and emaciated. One goat was sufficiently debilitated to warrant humane euthanasia.
